Further, the feed comprises the following raw materials in parts by weight: 25-35 parts of polyester resin, 10-14 parts of industrial gelatin, 5-8 parts of filler, 4-5 parts of anti-fouling agent, 2-3 parts of tall oil fatty acid calcium, 2-4 parts of colloidal calcium carbonate, 15-25 parts of diluent, 3-6 parts of pigment, 4-7 parts of emulsifier, 2-5 parts of defoaming agent, 3-5 parts of flatting agent, 4-6 parts of curing agent and 1-2 parts of antioxidant.
Further, the feed comprises the following raw materials in parts by weight: 30 parts of polyester resin, 12 parts of industrial gelatin, 6 parts of filler, 4 parts of anti-fouling agent, 2 parts of tall oil fatty acid calcium, 4 parts of colloidal calcium carbonate, 20 parts of diluent, 4 parts of pigment, 5 parts of emulsifier, 4 parts of defoaming agent, 4 parts of leveling agent, 5 parts of curing agent and 1 part of antioxidant.
Further, the filler comprises kaolin, mica powder, calcium carbonate and aluminum hydroxide, and the mixing ratio of the kaolin, the mica powder, the calcium carbonate and the aluminum hydroxide is 2:2:1: 1.
Further, the anti-pollution agent comprises sodium alkyl sulfonate, sodium fatty alcohol ether sulfate, a solubilizer, water and sorbic acid, wherein the mixing ratio of the sodium alkyl sulfonate, the sodium fatty alcohol ether sulfate, the solubilizer, the water and the sorbic acid is 2:6:2:4: 1.
Further, the tall oil fatty acid calcium comprises a mixture of oleic acid, linoleic acid and isomers thereof.
Step 1: 30 parts of polyester resin, 20 parts of diluent, 4 parts of anti-fouling agent and 6 parts of filler are put into a stirring container, the polyester resin main body can have an anti-fouling effect through sodium alkylsulfonate and fatty alcohol ether sodium sulfate contained in the anti-fouling agent, the polyester resin main body can be prevented from having an anti-corrosion effect through sorbic acid contained in the anti-fouling agent, the surface of the coating is prevented from being polluted, the shrinkage characteristic of the polyester resin can be well solved through light alumina contained in the filler, the polyester resin is prevented from shrinking to form cracks after being coated, and the first coating is obtained.
Step 2: and then 12 parts of industrial gelatin, 4 parts of colloidal calcium carbonate and 2 parts of tall oil fatty acid calcium are added into the first coating, the mixture is fully stirred in a stirring container to obtain a second coating, the second coating has the characteristic of viscosity through the industrial gelatin, the second coating can be coated on a wall, the second coating can obtain a further anti-fouling effect through the tall oil fatty acid calcium, a layer of fatty acid soap can be adsorbed on the surface of the second coating through the colloidal calcium carbonate contained in the second coating, CaCO3 has colloid activation performance, the colloidal calcium carbonate is insoluble in water, and the outer wall of the coating can be isolated from liquid.
And step 3: then add 4 parts of pigment into the second coating, 5 parts of emulsifier, 4 parts of defoaming agent, 4 parts of flatting agent, 5 parts of curing agent and 1 part of antioxidant and fully stir and obtain the third coating, can make the third coating possess the colour that needs through adding pigment in the second coating, can make the third coating emulsification thick through the emulsifier, be convenient for the third coating to paint on the wall body, can avoid forming a large amount of bubbles in the third coating stirring process through the defoaming agent, can make the third coating paint in-process even level and smooth through the flatting agent, can make the coating paint after scribbling fast solidification through the curing agent, can avoid the third coating oxidation yellowing through the antioxidant, improve the stability of third coating main part simultaneously, the anti-soil effect of third coating has further been improved.
