Anti-corrosive coating

Abstract

The invention discloses an anti-corrosive coating and relates to the technical field of coatings. The anti-corrosive coating is composed of the following raw materials in parts by mass: 15 parts of a titanium nano polymer, 8 parts of kaolin, 7 parts of feldspar, 30 parts of cerium oxide, 16 parts of petroleum resin, 12 parts of high chlorinated polyethylene resin, 25 parts of vinyl resin, 8 parts of hydroxyethyl cellulose, 5 parts of talc powder, 7 parts of precipitated barium sulphate, 7 parts of ethidene diamine, 12 parts of cyclohexanone, 2 parts of a coalescing agent, 1 part of an adhesive, 5 parts of pigments, 0.3 part of a defoamer, 0.5 part of a thickener and 4 parts of red lead. The anti-corrosive coating processed by the petroleum resin can accelerate the drying speed of the film, and the acid resistance, alkali resistance and weather resistance of the film are improved. By selecting phenolic resin and rosin as an adhesive, the phenolic resin is strong in constant temperature adhesive force, and the defect that a conventional coating is likely to crack is overcome. According to the coating, the cost of manufacturing raw materials is lowered, and the coating has antirust and anti-corrosive functions.

Description

technical field [0001] The invention relates to an anti-corrosion coating, which belongs to the technical field of coatings. Background technique [0002] For some substrates, when they are exposed, they are easily vulcanized due to the erosion of substances in the air, which affects the mechanics, heat resistance, weather resistance, wear resistance and corrosion resistance of the substrate. In response to this technical problem, many people are now studying how to reduce the vulcanization of the substrate. One of the methods is to spray paint on the substrate. The existing paint has a single function and cannot meet the needs of traditional paints. The cost of raw materials for making paints is relatively high, and the manufacturing process is relatively complicated. Generally, paints do not have multiple functions such as anti-rust and anti-corrosion. This is the defect of traditional coatings. Contents of the invention [0003] In view of the above problems, the tech...
