Metal antirust paint and preparation method thereof

Abstract

The invention relates to metal antirust paint and a preparation method thereof and belongs to the technical field of paint. The metal antirust paint comprises raw materials in parts by weight as follows: 5-10 parts of iron oxide red, 10-20 parts of polystyrene resin, 30-40 parts of methylbenzene, 10-20 parts of xylene, 5-10 parts of dibutyl phthalate, 10-20 parts of ethyl acetate, 1-5 parts of lead naphthenate, 8-15 parts of petroleum calcium sulfonate, 5-12 parts of gasoline, 3-5 parts of rosin, 3-5 parts of a flatting agent, 1-3 parts of a drier and 5-8 parts of an anti-precipitation agent. According to the preparation method, polystyrene is taken as a raw material, iron oxide red is taken as pigment, methylbenzene, xylene and ethyl acetate serve as a mixed solvent, the materials cooperate with lead naphthenate and petroleum calcium sulfonate, rosin, the anti-precipitation agent, the flatting agent and the drier are added, and accordingly, the multifunctional antirust paint is prepared; the multifunctional antirust paint has more excellent antirust performance than other iron oxide red antirust paint adopting a polystyrene material and can replace iron oxide red antirust paint.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof. More specifically, the invention relates to a metal antirust coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] The protective effect of coatings on metal is very important. At present, there are many materials for anti-rust coatings, especially iron red anti-rust coatings. Because the production cost of this kind of antirust paint is low, and the production process is simple. With the rapid development of my country's electrical industry, polystyrene foam is widely used as packaging materials, which become waste products after one-time use. Due to the high chemical stability of polystyrene, it neither rots nor decomposes after flowing into nature, thus Cause serious environmental pollution, this kind of pollution is getting worse day by day.
