Description

A kind of high hydrophobicity, high thermal conductivity and high-adhesiveness interface coating
Technical field
The present invention relates to a kind of metallic surface functional paint, the composition of the functional paint that particularly a kind of evaporator surface of compressed air conditioner device is used with high hydrophobicity, high thermal conductivity and high-adhesiveness.
Background technology
In the prior art, Chinese invention patent ZL 001 10559.0 disclose a kind of high hydrophobicity, high thermal conductivity and high-adhesiveness interface coating (hereinafter to be referred as: three property interface coatings).There are three problems in this three property interface coatings, and used dispersion medium is an industrial toluene in problem one, the three property interface coating, and by the infringement classification to HUMAN HEALTH, toluene belongs to second class, promptly harmful to a certain extent or virulent slightly solvent; By the classification of the hazardness under factory's working conditions, toluene belongs to second class, i.e. the toxic solvent.According to the TJ36-79 (industry hygiene standard) of China's promulgation in 1980, (maximum allowable-concentration MAC) is 100mg/m to toluene vapor maximum permitted concentration in the air 3It is dispersion medium that three property interface coatings adopt industrial toluene, and its reason is that toluene is the good solvent of film forming base-material, and low price.Solia particle in problem two, the three property interface coatings is divided into two classes: a class is reinforced heat conduction * 00 colloidal graphite powder, and its initial median size is 1.5 microns (μ m), or universal aluminium powder, the aluminium powder particulate is small flaky texture, and thickness is 0.1~2.0 μ m, and diameter is 1~200 μ m; Another kind of is the R202 of morphology effect, and it is the aerosil of handling through silicone oil, and initial median size is 12 nanometers (nm), is hydrophobic fully.The initial median size of this two classes solia particle differs greatly, and is example with * 00 colloidal graphite powder and R202, and the ratio of the initial median size of the former with the latter is 1500/12=125.So the poor stability of this three property interface coatings, the precipitation of generation solia particle.Problem three, film forming base-material and advantages such as wherein the solia particle compatibility is good, and snappiness and adhesive power are stronger relatively though film in former three property interfaces, its face hardness is relatively poor, and hydrophobicity is not very high.
Summary of the invention
A kind of high hydrophobicity, high thermal conductivity and high-adhesiveness interface coating are the succession and the development of former three property interface coatings.Therefore, the objective of the invention is the harm of the pollution of HUMAN HEALTH and environment is reduced to alap limit; Adopt the best collocation of solia particle, make morphology effect and reinforced heat conduction combination; Solve the stability of coating; Improve the hydrophobicity and the hardness of film coated surface, a kind of good stability is proposed, environmental pollution is little, hardness is higher, a kind of preferably high hydrophobicity of hydrophobic performance, high thermal conductivity and high-adhesiveness interface coating (hereinafter to be referred as: three property interface coating modified versions).
The present invention is achieved using the following method.
The follow-on composition of three property interface coatings includes film forming base-material, dispersion medium, solia particle and auxiliary agent.
1. the film forming base-material selects for use, film forming base-material in the former three property interface coatings is a PSI, the compatibleness of PSI and solia particle is good, sticking power and hydrophobicity are better, the follow-on film forming base-material of these three property interface coatings is still selected the W33-15 (toluene solution of PSI for use, in the solution, the mass ratio of PSI and toluene is 1: 1, the R/Si=1.47 of PSI, R C6H5/ R CH3=0.48).
2. selecting for use of dispersion medium selected environmental pollution low and the solvent that can mix with film forming base-material (PSI) or their mixed solvent for use.
In coatings industry, solvent be general reference those be used for dissolving the film forming base-material, form and be convenient to the liquid of constructing and in the process that formation is filmed, vaporing away.
Solvency power, as one of main characteristic of solvent, relatively scientific methods is to quantize with " principle that solubility parameter is close ".Definition according to Hull De Bulande (hildbrand):
δ=(ΔE/V) 1/2
In the formula: δ is a solubility parameter, (the J/m of unit 3) 1/2, Δ E is the internal cohesive energy of every mole of material, V is a molecular volume.From physical significance, δ is an Intermolecular Forces in the unit volume: when the δ of two kinds of liquid is identical, these two kinds of liquid can dissolve each other; When liquid identical with the δ of solid particulate; then solid particulate can lyolysis in solution; from the thermodynamics viewpoint; liquid mixes with solid particulate with liquid and liquid, and in constant temperature constant volume condition, spontaneous direction of carrying out is the reduction of system's free energy; according to this principle; can derive, when the absolute value of the difference of two kinds of materials (liquid and liquid, liquid and solid particulate) solubility parameter | Δ δ |<2.660 * 10 3~3.683 * 10 3(J/m 3) 1/2The time, can think and can dissolve each other, certainly | Δ δ | more little mutual solubility is just good more.Because the solubility parameter of PSI fails to find definite data, the approximate here solubility parameter Δ δ that gets its good solvent toluene Toluene=18.21 * 10 3(J/m 3) 1/2Be its reference value.
1 (hereinafter to be referred as trichloroethane), rational formula are CCl 3CH 3, it is one of minimum material of toxicity in aliphatic halogenated hydrocarbon.At working space maximum acceptable concentration (MAC), be defined as 1900mg/m in the U.S. 3, be defined as 1100mg/m in Japan 3, than toluene 100mg/m 3, exceed more than ten times.Its solubility parameter δ Cl=19.64 * 10 3(J/m 3) 1/2, δ ClToluene=19.64 * 10 3-18.21 * 10 3=1.43 * 10 3<2.66 * 10 3, as seen, trichloroethane can dissolve the film forming base-material.
2-butanone (claiming methyl ethyl ketone, methylethylketone again, hereinafter to be referred as butanone), molecular formula is CH 3COC 2H 5, it belongs to the lower toxicity material, and in the working space, maximum acceptable concentration is 590mg/m 3, than toluene 100mg/m 3, exceed nearly five times.Butanone is contaminate environment not too, because its volatility is good, is decomposed into other material easily in air.Its solubility parameter is δ b=19.03 * 10 3(J/m 3) 1/2, δ bToluene=0.82 * 10 3<2.66 * 10 3, visible butanone can dissolve the film forming base-material.
Viscosity is divided into kinetic viscosity μ and kinematic viscosity υ=μ/ρ, and ρ is a density in the formula, and the unit of kinetic viscosity and kinematic viscosity is respectively Pas and m 2/ s.Viscosity also is one of main characteristic of solvent.Press the big minispread of power viscosity number value, trichloroethane, toluene, butanone are respectively 0.903mPas, 0.5866mPas, 0.423mPas.With volume ratio, two parts of butanone, the kinetic viscosity μ of a mixed solvent of forming of trichloroethane Mix=2 * 0.423/3+0.903/3=0.583mPas is close with toluene.
Evaporation rate is that benchmark promptly is taken as 1 with the n-butyl acetate rate of volatilization, presses the rate of volatilization speed and arranges, and butanone, toluene, trichloroethane are respectively 4.65,1.95,1.5.
Surface tension, is respectively 28.53mN/m, 25.56mN/m, 24.60mN/m at toluene, trichloroethane, butanone, and the three is more or less the same.
In sum, because the butanone volatilization is very fast, should not make the follow-on dispersion medium of three property interface coatings separately.Therefore, two kinds of solvents can be selected one for use: trichloroethane; Its two: the mixed solvent of trichloroethane and butanone.
3. solia particle selects for use, in the former three property interface coatings for strengthen the thermal conductivity of filming select for use median size be micron (μ m) level, general aluminium powder or * 00 colloidal graphite powder that thermal conductivity is very high, thereby caused the deposited phenomenon of three property interface coating solia particles, masking liquid stable bad.For addressing this problem, select for use nano level ordinary carbon black pigment to replace them, nano level ordinary carbon black pigment initial particle is 26~37nm, specific surface area is 80~200m 2/ g has kept the aerosil R202 that handles through silicone oil in the former three property interface coatings.The initial median size of ordinary carbon black pigment is 26~37nm, and it and silicone oil are handled particle diameter ratio 26/12~37/12=2.17~3.08 of aerosil, has howed for a short time than 125.In the system that forms by solia particle and liquid, as not having chemical affinity between particulate and the liquid, i.e. both solubility parameter Δ δ>3.680 * 10 3(J/m 3) 1/2, then this system is unsettled on thermodynamics, solia particle will precipitate; But learn from colloid chemistry, when the particle diameter of particulate during less than 100nm, when this particulate is subjected to the bump of surrounding liquid molecule, produce unbalanced force owing to stressed area is very little, these particulates just produce Blang (R.Brown) motion, it is a kind of irregular thermal motion, and these particulates are evenly distributed in the liquid, thereby has dynamic (dynamical) stability.It has been generally acknowledged that particle diameter is called nanoparticle less than the particle of 100nm.So aerosil and ordinary carbon black pigment belong to nano level.But as black pigment, at coatings industry, it is the most difficult that sooty disperses.This is because carbon black is a kind of high dispersive, porous lyophobic dust, but various active functional group (carboxyl, hydroxyl, carbonyl) is arranged on its surface, thereby has formed also possess hydrophilic property of carbon black.Like this, carbon black has the spontaneous trend that forms unsettled suspended particle in coating, in the storage process of coating, regroup to wadding aggressiveness (the initiating particle group of joining with face) and agglomerate (the initiating particle group of joining with point, angle), thick retrogradation and deposited phenomenon appear returning.For solve the problems referred to above that carbon black produces in coating, adopting silicone oil that carbon black is carried out hydrophobization handles, make active function groups absorption silicone oil on the carbon blacksurface, and for preventing silicone oil and the solvent competitive adsorption to active function groups, used silicone oil does not add any solvent that makes it to dilute.China's common pigments dispersing apparatus as triple-roller mill, sand mill, high speed dispersor and colloidal mill etc., all can not make the particle size dispersion of solia particle to nano level.With the thinnest colloidal mill of dispersion, more than the dispersion particle diameter 1000nm of its minimum.Ultrasonic homogenizer (ultrasonic wave assimilator Supersonichomogenizen), its oscillator produces ultrasonic vibration under external force (alternating-current) effect.This vibration meeting is outwards propagated in the medium around.In fluent meterial, propagate, in a vibrational period, have half period compression half period to expand.Because vibration is very fast, as 2.5 ten thousand hertz (Hz), expanding the semi-period, liquid has little time to expand and bubble occurs.Be compressed at compression semi-period bubble, then the anxious collapse of bubble, and produce cavitation.The moment that disappears in the hole, the pressure of this moment can reach hundreds of MPas (MPa), thereby plays very complexity and the intense mechanical stirring action, makes solia particle in the liquid be distributed to the scope (1~100nm) of colloidal solid gradually.There is wadding to gather to ordinary carbon black pigment and forms the dissemination of oarse-grained carbon black, grain diameter is recovered can accomplish near initial particle 26~37nm by ultrasonic homogenizer with agglomeration.Active group absorption silicone oil on the carbon black forms complete hydrophobic nanoparticle like this.
In sum, the solia particle carbon black that adopts R202 (aerosil of handling through silicone oil) and handle through silicone oil.
4. auxiliary agent adopts vinyl three tertiary butyl peroxy-silanes to make coupling agent in the former three property interface coatings, solves the high-adhesiveness of filming in three property interfaces.These three property interface coating modified versions have kept YGO-1401 in the former three property interface coatings (concentration is 40% vinyl three tertiary butyl peroxy-silane toluene solutions) and have made coupling agent, though the PSI among the film forming base-material W33-15 of former three property interface coatings has the good relative advantage preferably with sticking power of compatibleness with solia particle, but hydrophobicity is poorer than pure methyl silicon resin, and the film coated surface difference of hardness.In order to overcome these shortcomings, add auxiliary agent slip(ping)agent-polyester modification dimethyl siloxane BYK--310 at three property interface coating modified versions, it is the matured product of German BYK company, very stable under common storing temperature, only degraded just appears in polyester chain when surpassing 200 ℃, its addition is decided on purposes, and consumption is less.Forming thickness on face only is several low molecular solid matter methyl thin layers, and its true contact angle is 103 °.
In sum, auxiliary agent adopts YGO-1401 (concentration is 40% vinyl three tertiary butyl peroxy-silane toluene solutions) and BYK-310 (polyester modification dimethyl siloxane).The silicone oil that the above-mentioned carbon black of handling through silicone oil is used can be silicone oil 201-1000, is dimethyl silicone oil, and viscosity is 1000mm 2/ s (medical sanitary level, Shanghai Resin Factory produces).
According to above-mentioned selection for the coating composition, the follow-on composition of three property interface coatings of the present invention includes film forming base-material, dispersion medium, solia particle and auxiliary agent.
The film forming base-material is that (toluene solution of PSI, in the solution, the mass ratio of PSI and toluene is 1: 1 to W33-15, the R/Si=1.47 of PSI, R C6H5/ R CH3=0.48), dispersion medium is the mixed solvent of trichloroethane or trichloroethane and butanone, solia particle is R202 (aerosil of handling through silicone oil) and the carbon black handled through silicone oil, auxiliary agent is YGO-1401 (concentration is 40% vinyl three tertiary butyl peroxy-silane toluene solutions) and BYK-310 (polyester modification dimethyl siloxane), the parts by volume of follow-on each composition of three property interface coatings is: W33-15:100, trichloroethane: 100~300, butanone: 0~200, R202:200~350, carbon black: 200~400, YGO-1401:8~12, BYK-310:4~6, silicone oil 201-1000:1~2.
Owing to comprehensively adopted the very low organic solvent of toxicity to make dispersion medium, the solia particle in the coating is a nano level, and ultrasonic technology and face are the methyl of solid matter, and three property interface coating modified versions have obvious improvement than former three property interface coatings, show:
1. owing to adopt ultrasonic technology that the solia particle in the coating is disperseed, ultrasonic wave produces the hole, surrounding fluid is easy to make solia particle to be dispersed to initial median size to hole strong wallop [hundreds of MPas (MPa)], the median size of aerosil is bordering on 12nm, and the ordinary carbon black pigment median size is bordering on 26~37nm.The more important thing is that ultrasonic dispersing is to carry out in airtight container, therefore the follow-on manufacturer of three property interface coatings can realize the zero release of organic solvent; For the follow-on use of three property interface coatings producer, as there is not the equipment of the recycling use of machine solvent, because it is the organic solvent of selecting for use is a hypotoxicity, healthy and atmospheric pollution also greatly reduced to the staff of working space.
2. because carbon black is carried out hydrophobicity processing and ultrasonic dispersing subsequently with silicone oil, solved the sedimentation problem in the former three property interface coatings.
3. owing to adopt the polyester modification dimethyl siloxane of trace, forming the face hydrophobicity of filming at three property interface coating modified versions has had improvement and face hardness stronger.
4. be applied to coatings industry about ultrasonic technology, its advantage can be summarized as follows:
(1) ultrasonic homogenizer can produce the combined effect of colloidal mill and high-shear homogenizer.Coating do not heat up, non-volatile, do not suck air.
(2) energy consumption is low, and unit consumption of energy is 1.5KWh/t only.
(3) structure is little, invests seldom, and some months can reclaim, and keeps in repair, cleans extremely easy.[referring to S.E.Booth.Ultrasonicass as a Method of Mixing, Dispersion and Homogenisation.Paint﹠amp; Resin, 1986,56 (6): 17~18.Translation: S.E. cloth grace.Stir the supersonic method of dispersion and homogeneous.Coating and resin, 1986,56 (6): 17~18]
