Abstract
The invention relates to a preparation method of a multifunctional water-borne woodenware close primer. A basic recipe of the primer is as follow: 40 percent-70 percent of emulsion, 2 percent-10 percent of coalescing agents, 0.1 percent-0.5 percent of antifoaming agents, 0.2 percent-1 percent of flatting agents, 0.1 percent-1 percent of base material moistening agent, 0.2 percent-1.5 percent of thickening rheological agents, 0.1 percent-0.3 percent of bacteriacide, 0.1 percent-1 percent of PH regulation agents, and 25 percent-40 percent of deionized water. The water-borne woodenware close primer has strong permeability, and excellent water resistance and closure, gallotannic acid in woods can be prevented from seeping to cause floating of colored paint, the adhesion between a base material and a coating is increased, and moisture in putty can be also prevented from being absorbed by the woods untimely to cause difficulty in coating the putty. The water-borne woodenware close primer is suitable for closed coating of surfaces of various dyeing plates, medium-fibrousness plates, artificial lagging boards, woods containing vegetable oil or gallotannic acid and the like.
Description
Technical field
The present invention relates to a kind of preparation method of water-borne wood coating priming paint, relate in particular to a kind of multifunctional aqueous wooden ware sealing priming paint that is applicable to various materials.
Background technology
Water-borne wood coating is because the advantage of its environmental protection aspect receives coating material production merchant and human consumer's concern always; But some problems that the solvent-borne type woodwork coating seldom runs into have also appearred in promoting the use of process; Water colour paint for example; Especially white or tinted paint, variable color immediately behind the dried coating film, cause with desired color not～cause.Though some solvent-borne type woodwork coating also has discoloration problem, speed can be so not fast, and the process of a gradual change is arranged, and therefore, the variable color of water-borne coatings and the variable color of solvent based coating are distinguished to some extent.Solving one of water-borne coatings bleeding simple effective method is exactly the application seal coat.
Existing phenylpropyl alcohol seal coat, sealing acrylic priming paint generally all are that the modulation of anionic emulsion forms, but have poor adhesive force, the shortcoming that alkali resistance is weak; Particle size of emulsion is bigger, and surface tension is also very big, generally is difficult to be penetrated in the inner tiny pore of ground, so can only rely on the effect that density that substrate surface films realizes back cover.
In water-borne coatings, polymkeric substance is scattered in the water with spheroidal particle, and each particle is made up of the high molecular polymer of different quantities.It is a nonhomogeneous system, and spheroidal particle has passed through a series of physical and chemical processes when water evaporation back, is broadly divided into that particulate is piled up, particulate melts and tie and the diffusion of the polymkeric substance end of the chain etc. could form a continuous thin film.Solvent based coating has directly formed continuous thin film after solvent evaporates, like nitro paint, acrylic coating etc.Or, form firmer film, like polyurethane coating, alkydpaints etc. through certain crosslinked.Therefore, the film forming initial stage of water-borne coatings films not fine and close, and after timber absorbed the moisture in the coating, in moisture evaporation exsiccant process, the trend of colored component in the timber being taken to the surface is arranged.In a word, the variable color of water-borne wood coating is that coating is done solid work the back horse back and just can be seen because due to the colored component in the timber was dissolved in the water of coating, physical process was the result of timber and coating dual function more than chemical process.And the variable color of solvent based coating is since in the coating molecular structure of film forming matter carried out resetting and produced, chemical process is more than physical process, and is little with the cognation of timber, just can observe after for some time.In aqueous woodware paint construction, the seal coat matched coating that is absolutely necessary.
Summary of the invention
The present invention selects self-crosslinking uncle acrylic emulsion for use, utilizes on the monomeric alpha-carbon atom of tertiary carbon to have abundant alkyl, has formed great space steric effect and shielding effect, not only also plays a protective role to self but also to unit on every side; Simultaneously because alkyl nonpolar, its homopolymer or have good weathering resistance, alkali resistance and water tolerance with other monomeric multipolymers can strengthen pigment wettability and dispersiveness, increases ADHESION OF PAINTS power and elasticity.Tertiary ethylene carbonate has the characteristics of alkali resistant, sealing excellence, oleophilic drainage in addition.Uncle's acrylic emulsion that the present invention selects for use has more tiny particle diameter, to the good penetrability of base material, and self-crosslinking is arranged, and can improve polymerization crosslinking density, improves closure.
So the aqueous wooden ware seal coat perviousness that the present invention processes is strong; Good water tolerance and closure prevent that Weibull in the timber from oozing out and cause colored paint to grow dim, and increase the sticking power between base material and the coating; Can prevent that also the moisture in the putty from being absorbed by timber prematurely, causes putty to be coated with and scrape difficulty.
In order to solve technical problem recited above; The present invention takes following technical scheme: the present invention relates to a kind of multifunctional aqueous wooden ware sealing priming paint, its basic recipe is: emulsion 40%～70%, film coalescence aid 2%～10%, skimmer 0.1%～0.5%, flow agent 0.2%～1%, base material wetting agent 0.1%～1%, thickener rheology agent 0.2%～1.5%, sterilant 0.1%～0.3%, PH regulator 0.1%～1%, deionized water 25%～40%.
Wherein, emulsion is selected self-crosslinking uncle acrylic emulsion for use.
Film coalescence aid is selected one or more combination of glycol ether, propylene glycol and alcohol ester-12 for use.
Skimmer is for containing the polyether-modified ZGK 5 of aerosil hydrophobic particulate.
Flow agent gathers the dimethoxy silane polymer for what do not influence recoat.
The base material wetting agent is the polyoxy silane polymer.
Thickener rheology agent is the hydrophobic association type polyurethane thickener.
The preparation method preparation technology that the present invention proposes a kind of multifunctional aqueous wooden ware sealing priming paint is following: stir deionized water, sterilant, the emulsion speed with 500r/min in high speed dispersor by the formulation weight ratio; Add film coalescence aid, skimmer then; Add base material wetting agent, flow agent successively after stirring 10min; Behind the restir 15min, mix up viscosity and pH value, cross and filter multifunctional aqueous wooden ware sealing priming paint.
The multifunctional aqueous wooden ware sealing priming paint perviousness that the present invention processes is strong; Good water tolerance and closure; Preventing that Weibull in the timber from oozing out causes colored paint to grow dim; Increase the sticking power between base material and the coating, can prevent that also the moisture in the putty from being absorbed by timber prematurely, cause putty to be coated with and scrape difficulty.Be applicable to various dyeing sheet materials, middle fibrousness plate, artificial lagging sheet material, contain the sealing application on the first-class surface of timber of vegetables oil or Weibull.
