Waterproof and impervious water-based cast steel coating

Abstract

The invention discloses a waterproof and impervious water-based cast steel coating. The waterproof and impervious water-based cast steel coating is prepared from, by weight, 20-30 parts of zircon powder, 15-20 parts of electro-fused mullite powder, 15-20 parts of quartz powder, 2-3 parts of lithium-based bentonite, 20-30 parts of glycerol trioleate, 5-15 parts of monobasic acid, 25-35 parts of isophthalic acid, 15-25 parts of vinyl acetate, 5-25 parts of trimellitic anhydride, 5-10 parts of flake graphite, 0.5-1 part of sodium carboxymethyl cellulose, 1-2 parts of sodium alkyl benzene sulfonate, 3-5 parts of a wetting agent, 1-10 parts of a defoaming agent and 10-18 parts of a drier. Compared with the prior art, the zircon powder, the electro-fused mullite powder and the quartz powder are added in the preparing process of the water-based cast steel coating, and therefore the waterproof and impervious performance of the coating can be increased; and meanwhile, magnesium chloride and barium chloride are further included in the water-based cast steel coating, and therefore the difficulty of sand removal and high-temperature cracks can be avoided, a coating is thin and uniform, it is guaranteed that the surface of a casting is smooth, the quality of the casting is effectively guaranteed, and the yield is effectively increased.

Description

technical field [0001] The invention relates to the field of paint preparation, in particular to a waterproof and anti-seepage water-based cast steel paint. Background technique [0002] In recent years, with the development of China's industry, the requirements for steel materials are getting higher and higher. Traditional cast steel materials use expensive zircon powder or graphite powder as the main raw material, and the graphite powder used is heavy in color, easy to dye, and mostly radioactive. Furthermore, after the high-temperature treatment of the traditional quartz sand coating, the coating is prone to sand sticking and cracking, the surface roughness of the casting is relatively high, it is difficult to meet the quality standard, and the amount of residual waste remains high. [0003] The object of the present invention is to overcome above-mentioned defect, make the novel water-based cast steel paint of waterproof and seepage resistance. The object of the presen...
