Embodiment 1
[0018] A solar water tank anti-corrosion paint raw material includes, in parts by weight: 5 parts of high-chlorinated polyethylene, 10 parts of polyvinyl acetate resin, 3 parts of silica sol, 4 parts of iron powder, 1 part of aluminum tripolyphosphate, 1 part of zinc phosphate, 7 parts of n-butanol, 3 parts of ethanol, 6 parts of tributyl phosphate, 4 parts of polyester modified polysiloxane, 3 parts of mica powder, 4 parts of precipitated barium sulfate, and 8 parts of concrete.
[0019] Further, the preparation method of the solar water tank anticorrosion coating comprises the following steps:
[0020] (1) Stir high-chlorinated polyethylene, polyvinyl acetate resin, and n-butanol at 350 rpm for 25 minutes to obtain a mixed solution;
[0021] (2) Add silica sol, concrete, iron powder, tributyl phosphate, and polyester-modified polysiloxane to the mixture obtained in step (1), stir at 350rpm for 25min, grind until the fineness is 150 mesh, and then Vacuum dehydration for 2.5 ...

Abstract
The invention relates to the field of coating, in particular to an anti-corrosive coating of a solar water tank and a preparation method of the anti-corrosive coating. An important part, namely the water tank, of a solar water heater is generally made of color steel plates, and the economic and attractive effects are realized; however, surface paint of the color steel plate of the solar water tank easily falls off, thereby influencing the durability and attractiveness of the water tank; coating can protect an outer casing of the water tank, however most of coating on existing market contains benzene, and the benzene is volatile and poisonous, and is hazardous to people and animals; therefore, the research and development of coating without poison and with strong adhesion force and anti-corrosive property to the color steel plate is urgent. The anti-corrosive coating is prepared from the following raw materials in parts by weight: high-chlorinated polyethylene, polyvinyl acetate resin, silicon sol, iron powder, aluminium triphosphate, zinc phosphate, n-butyl alcohol, ethyl alcohol, tributyl phosphate, polyester modified polysiloxane, mica powder, precipitated barium sulphate and concrete. The anti-corrosive coating has the advantages that the anti-corrosive property is good, the adhesion force is strong, a coating film is dense and harder, the anti-pollution ability is strong, and the benzene is not contained.
Description
technical field [0001] The invention relates to the field of coatings, in particular to a solar water tank anticorrosion coating and a manufacturing method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, people have paid more and more attention to environmental protection issues, and solar water heaters have also been promoted. An important part of solar energy—the water tank is generally made of color steel plate, which is economical and beautiful, but the surface paint of the color steel plate of the solar water tank is easy to fall off, which affects the durability and appearance of the water tank. And most of the paints on the market now contain benzene. According to the "List of Dangerous Goods" (GB12268-90) of the People's Republic of China, benzene belongs to the medium flash point liquid in the third category of dangerous goods flammable liquids. And because of its volatility, it may cause local accumulation...
