Corrosion resistant transparent physical and chemical resin

Abstract

This invention relates to an anticorrosive transparent physicochemical resin, which is composed of: vinyl resin 50-1500 parts peroxide 5-50 parts, two crosslinkers both 50-400 parts, and thickener 50-500 parts. The resin has such advantages as adequate curing, high corrosion resistance, the same properties as epoxy resin, acrylic resin, unsaturated polyester resin, polyurethane and melamine formaldehyde resin, and high surface contamination resistance.

Description

[technical field] [0001] The invention relates to the technical field of polymer chemistry, in particular to a corrosion-resistant transparent physical and chemical resin (special coating). [Background technique] [0002] At present, the vinyl resin used for decorative surface treatment at home and abroad, such as laboratory countertops, food cabinets, disinfection cabinets, etc., is an addition reaction product of an epoxy resin and an unsaturated monobasic acid containing double bonds. It retains the high mechanical strength, heat resistance and chemical resistance of epoxy resin. Its unsaturated polyester is simple and convenient in process, but its chemical resistance is not very high. For strong acids such as 98% sulfuric acid and 65% nitric acid The erosion of the decorative countertops has obvious variations in the gloss and color, which cannot meet the higher requirements of consumers for the corrosion resistance and color of the decorative countertops.
