Technical Field
The invention belongs to the field of coatings, and particularly relates to an anti-fouling self-cleaning full-effect all-in-one wall paint.
Background
Emulsion paints are a large class of synthetic resin emulsion paints represented by acrylic ester copolymer emulsions. The latex paint is water-dispersive paint, which is prepared by using synthetic resin emulsion as base material, grinding and dispersing filler and adding various assistants. The emulsion paint has the advantages different from the traditional wall paint, such as easy brushing, quick drying, water resistance of paint film, good scrubbing resistance and the like.
In the prior art, the interior wall latex paint has the defects of easy bulging and peeling and poor dirt resistance of finish paint. Especially in the scenes with anti-pollution requirements of schools, hospitals, homes and the like, the anti-pollution self-cleaning application requirements are difficult to meet.
Disclosure of Invention
In view of the above, the invention provides an anti-fouling self-cleaning full-effect wall paint, which aims to solve the problems that the paint is easy to bulge and peel off during over-inflation and the paint is not anti-fouling after being coated.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
an anti-fouling self-cleaning full-effect all-in-one wall paint comprises the following components in parts by weight:
30-50 parts of organic silicon modified acrylate;
1-2 parts of a pH regulator;
4-5 parts of propylene glycol;
20-30 parts of pigment;
3-5 parts of a film-forming assistant;
0.2-1 part of defoaming agent;
1-3 parts of microcrystalline wax emulsion;
1-3 parts of a sterilization preservative;
2-5 parts of a thickening agent;
4-6 parts of a wetting dispersant;
30-40 parts of a filler;
30-40 parts of deionized water.
The film-forming additive is an alcohol ester dodecafilm-forming additive;
the pH regulator is AMP-95;
the defoaming agent is one of pure silicone oil, a silicone oil solution and silicon paste; the defoaming agent can remove foam components in the coating. If the bubbles do not disappear during film formation, the paint may shrink or become pin holes.
The sterilization preservative is methyl chloroisothiazolinone, and the correct use of the sterilization preservative can ensure that the paint is not damaged by bacteria and algae, thereby ensuring the quality of the paint in the guarantee period. The sterilization mechanism of most of the sterilization and disinfection preservatives is that proteins of microorganisms are denatured through the contact of the bactericides and the microorganisms, the cell activity of the microorganisms is reduced, bacteria are promoted to die, and the service life of finish paint is further prolonged.
The thickener is a mixture of polyurethane and inorganic cellulose, and the ratio of the polyurethane to the inorganic cellulose is 0.5-2.5. The polyurethane and the inorganic cellulose form a thickening system, so that the stability and the excellent mechanical property of the finish paint can be enhanced, and the polyurethane and the inorganic cellulose can enhance the water resistance of the wall surface.
The wetting dispersant is alkylphenol polyoxyethylene.
The filler is wollastonite powder, the wollastonite powder has low surface tension, and the hydrophobicity of the finish paint can be improved.
The content of the organic silicon in the organic silicon modified acrylate is 10-12%, and the PH value is controlled to be 6-8 by the PH regulator. The pH regulator controls the pH value of the finish paint to be 6-8, so that the decomposition of the organic silicon modified acrylate can be reduced, and the components of the organic silicon modified acrylate are improved.
The propylene glycol can enhance the dissolving amount of the organic silicon modified acrylate in the finish paint and inhibit the decomposition of the organic silicon modified acrylate, the propylene glycol can improve the content of the organic silicon modified acrylate in the finish paint, and the propylene glycol can degrade the freezing point of water, thereby playing a role in preventing freezing.
The organic silicon modified acrylate is used as a coating base material, the weather resistance and the pollution resistance are excellent, the content of the organic silicon modified acrylate is limited, when the content of organic silicon is too high, the formed finish emulsion is unstable, when the content of the organic silicon is higher than 12%, the finish is easy to gel, the cost of the organic silicon is high, and the cost of the finish can be controlled by controlling the content of the organic silicon in the organic silicon modified acrylate.
The ratio of the organic silicon modified acrylate to the microcrystalline wax solution is 15-23:1, and the ratio of the organic silicon modified acrylate to the filler is 1: 1-1.2.
The preparation of the microcrystalline wax emulsion comprises the following steps:
s1: cutting microcrystalline wax to less than 1cm3Heating the fragments in a water bath with constant temperature of 80-85 ℃ until the fragments are completely melted;
s2: then adding methyl hydrogen-containing silicone oil, uniformly stirring, and then adding an emulsifier, wherein the emulsifier is formed by compounding emulsifier Span-80 and emulsifier Tween-80 in equal weight ratio;
S3: adding 8-10 parts of hot water with the temperature of 80-90 ℃ while stirring, continuously stirring and reacting for 15-20min to obtain the microcrystalline wax emulsion.
The ratio of the microcrystalline wax to the methyl hydrogen-containing silicone oil to the emulsifier is 10: 3: 2.
the addition of the microcrystalline wax can enable a plurality of tiny wax crystals to be formed on the surface of the film layer, so that liquid is difficult to stand on the surface of the film layer, the hydrophobicity of the microcrystalline wax is improved, the waterproof performance of the microcrystalline wax is improved again after the microcrystalline wax is modified by methyl hydrogen-containing silicone oil and an emulsifier, and the film can be easily formed at low temperature.
The self-cleaning capability and the waterproof capability of the finish paint can be enhanced under the compounding action of the microcrystalline wax and the organic silicon modified acrylate.
A preparation method of an anti-fouling self-cleaning full-effect all-in-one wall paint comprises the following steps:
b1: weighing the materials according to the proportion of the components;
b2: adding deionized water and adding a pH regulator under stirring at 200-300 r/min;
b3: under the stirring of 300-350r/min, the temperature is controlled to be 80-85 ℃, and the wetting dispersant, the sterilization preservative, the defoamer, the thickener, the organic silicon modified acrylate, the pigment and the filler are added, stirred for 5-10min and then stirred for 30-40mim under the stirring of 3000-4000 r/min;
b4: under the stirring of 400-500r/min, adding propylene glycol, film forming assistant and microcrystalline wax emulsion, and stirring for 30-40 min.

As can be seen from examples 1-2 and comparisons 1-4, the combination of the microcrystalline wax of the finish paint and the organosilicon modified acrylate can enhance the self-cleaning ability and the waterproof ability of the finish paint. The addition of the microcrystalline wax can enable a plurality of tiny wax crystals to be formed on the surface of the film layer, so that liquid is difficult to stand on the surface of the film layer, the hydrophobicity of the film layer is improved, the water resistance of the microcrystalline wax is improved again after the microcrystalline wax is modified by methyl hydrogen-containing silicone oil and an emulsifier, and the film can be easily formed at low temperature. The adhesiveness and the ductility of the organic silicon modified acrylate are greatly improved, and the organic silicon modified acrylate and the wollastonite powder can be more compact in the using process under the matching condition, so that the situations of swelling and falling of the finish paint are greatly reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
