Description
Technical field
The invention belongs to the dry powder paint field, relate in particular to a kind of green powdered paint and preparation method thereof.
Background technology
Along with science and technology development, people are more and more deep to the understanding of environment protection and Sustainable development.In coatings industry, replacing with serious pollution solvent based coating with water-borne coatings, powder coating is trend of the times, and water-borne coatings has obtained using widely.But the building water emulsion coating that uses is made up of polymer emulsion, color stuffing, various auxiliary agent and water now, and wherein auxiliary agent and water are used in order to produce with accumulating coating, account for the over half of coating weight and price.Major part is water (accounting for 60%) in the aqueous architectural latex coating, and solid content only accounts for 40%, and storage and use liquid latex coating need be used a large amount of storage tanks, and the recycling of these plastics or irony storage tank also needs lot of manpower and material resources.So not only increased cost, and caused the waste of resource, also contaminate environment.
Summary of the invention
The object of the present invention is to provide a kind of green powdered paint, add the water stirring during use and can be made into traditional emulsion paint now, have existing with the same performance of coating, solved a traditional emulsion paint stability and the high difficult problem of carrying cost, made emulsion paint be able to stablely pack and sell with form low carrying cost with a kind of.
Another object of the present invention is to provide the preparation method of this green powdered paint.
Green powdered paint of the present invention is made up of the material of following weight percent:
Redispersible polymer latex powder 5～20%
White cement 20～40%
Lime carbonate 20～45%
Titanium dioxide 5～25%
Diatomite 2～8%
Wilkinite 1～2%
Ether of cellulose 0.2～0.5%
Defoamer 0.2～0.5%
Tinting pigment 0～4%
In the above-mentioned prescription redispersible polymer latex powder be a kind of second-order transition temperature for-10～10 ℃, form, contain by vinylformic acid (ester) monomer and methacrylic acid (ester) monomer copolymerization crosslinking functionality spatial stability contain spray-dried being prepared from of siloxanes water-soluble polymers emulsion.It is the film forming base-material of dry powder paint, and its consumption is directly connected to the performance of dry powder paint, and its consumption is crossed the low intensity and the adhesive property that can influence coating, and too high meeting influence rate of drying and increase cost, and its preferable amount ranges is 5～20%.
White cement mainly plays enhancement, but its consumption can not be excessive, otherwise can influence the coating application performance, and its preferable amount ranges is 20～40%.
Lime carbonate be widely used, inexpensive filler, the flowability that can promote coating can make the delustring of filming, and the opacifying power that improves coating is had contribution, can also reduce the cost of coating, its preferable amount ranges is 20～45%.
Titanium dioxide has alkali resistance, acid resistance, refractive index height, good, the good chemical stability of opacifying power, according to the difference that interior exterior wall requires, can select anatase thpe white powder or Rutile type Titanium Dioxide for use, and its preferable amount ranges is 5～25%.
Diatomite has unique porous particle structure can make that slick to be coated with floor height coarse, produces the matting effect, can also the adjustment coating and the cohesive force of basal plane.In addition, because diatomaceous porousness and the just very fast drying of the coating of viscosity, its preferable amount ranges is 2～8%.
Wilkinite is a time white powder, has good cohesiveness, adsorptivity, thixotropy, suspension, plasticity-and lubricity, and its preferable amount ranges is 1～2%.
Ether of cellulose is a kind of effective thickening material and auxiliary rheological agents, can adopt in methylcellulose gum, carboxymethyl cellulose, ethyl cellulose, Natvosol, the hydroxypropylcellulose any one or more than one mixture, it adds the rheological property that affiliation improves dry powder paint, if but consumption is crossed the water resistance that conference reduces dry powder paint, its preferable consumption is 0.2～0.5%.
The adding of defoamer mainly is to produce bubble in order to prevent in construction process, and its preferable amount ranges is 0.2～0.5%.
The adding of tinting pigment is in order to increase the ornamental of coating, and consumption is 0～4%, can require to add color dye or do not add tinting pigment according to different decorations.
The preparation method of green powdered paint of the present invention is as follows:
With above-mentioned each component by weight percentage ratio drop into stirrer, after mixing, packing can make the finished product green powdered paint.
During construction, green powdered paint is added water, the back spraying that stirs gets final product, wherein coating: water=5: 3～5: 4.
The present invention compared with prior art has following advantage and beneficial effect:
(1) green powdered paint of the present invention is a solid, can be as the cement paper bag packing, do not need metal bucket or plastic tank packing, solved an emulsion paint stability and the high difficult problem of carrying cost, make emulsion paint be able to pack and sell with a kind of prescription form stable and low carrying cost; Add the water stirring during use and can be made into traditional emulsion paint now, have existing with the same performance of coating;
(2) need not add various chemical assistants in traditional emulsion paint in the green powdered paint process for preparation of the present invention, there is not any volatilization pungent, some used industrial chemicals of existing emulsion paint had both been saved, the volatile organic compounds (VOC) that causes environmental pollution can be reduced again, real zero VOC building coating can be made;
(3) green powdered paint of the present invention have save time, economize operation, water-proof, advantage such as paint film is smooth, hardness is high, intensity is big, ageing-resistant, cracking resistance, be the decorative product that replaces traditional glue putty, the two-in-one novel wall surface of emulsion paint, can be widely used in the decoration of exterior wall in the buildings.
