Preparation method of abrasion-resistant and corrosion-resistant non-sticky coating

Abstract

The invention relates to a preparation method of an abrasion-resistant and corrosion-resistant non-sticky coating and belongs to the field of coatings. Aiming at the problems that organic fluorine resin in a current traditional non-sticky coating fluoro coating is high in fusion temperature and is not dissolved in common solvents, an organosilicone non-sticky coating can achieve a good non-sticky effect but is poor in hardness and cannot meet shovel test requirements, a nano-ceramic coating is high in hardness, but a film is crispy, and paint easily falls off after the film encounters hard objects, kieselguhr is subjected to high-temperature activation and acid modification, the kieselguhr is loaded with silicon carbide, the hardness of the kieselguhr is improved, the kieselguhr and polybutadiene are mixed, wrapped and fixed, and then the mixture is mixed with alkyd resin easily dissolved in the common solvents; the mixture, oil-soluble silicone wax, paraffin and the like generate a mixed reaction, finally through a maleic anhydride modification reaction, corrosion resistance is improved, and therefore the abrasion-resistant and corrosion-resistant non-sticky coating is prepared.

Description

technical field [0001] The invention relates to a preparation method of a wear-resistant, corrosion-resistant and non-stick coating, which belongs to the field of coatings. Background technique [0002] Non-stick coating is a special coating whose coating surface is not easily adhered by other sticky substances or easily removed after adhesion. This kind of coating is widely used in household appliances, cooking utensils, automobiles, machinery, chemical industry and other industries due to its anti-adhesive properties such as extremely low surface energy, small friction coefficient and easy sliding. As a kind of environmentally friendly special coating with strong practicability and high technical content, non-stick coating has attracted more and more attention from coating research and development workers. [0003] The fluorine coatings that dominate the market are not suitable for iron substrates. 1. The sintering temperature of fluorine coatings is high, higher than 380...

Problems solved by technology

[0005] The technical problem to be solved by the present invention: In view of the high melting temperature of the organic fluorine resin in the current traditional non-stick coating fluorine coating and the insolubility in common solvents, while the organic silicon non-stick coating can achieve a good non-stick effect, but the hardness is poor, Unable to meet the requirements of the shovel test, the hardness of the nano-ceramic coating is high, but the coating film is brittle and the paint is easy to fall off when encountering hard objects. The present invention activates diatomite at high temperature, modifies it with acid, and then loads it with silicon carbide to improve its performance. Hardness, and then mix it with polybutadiene to wrap and fix it, then mix it with alkyd resin that is easily soluble in common solvents, react with oil-soluble silicone wax, paraffin wax, etc., and finally pass maleic anhydride modification reaction, Improves corrosion resistance, resulting in wear-resistant, corrosion-resistant, non-stick coatings
