Abstract

The invention discloses a multifunctional modified crylic acid polyurethane rubber coating and a preparation method thereof. The coating comprises two components, wherein organic silane modified acrylic resin and polyester modified acrylic resin are taken as film formation components, and polyether modified diisocyanate prepolymer and aliphatic series isocyanate polymer are taken as curing agent. The coating has excellent combination properties, such as adhesive force, gloss, richness, distinctness of image, weather resistance, abrasive resistance, high low temperature resistance, flexibility, solvent resistance, and stain resistance. According to the coating, the bottom and the surface are combined, so that a primer does not need to be sprayed, the technology is simple, the energy for construction is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to a rubber paint and a preparation method, in particular to a multifunctional modified acrylic polyurethane rubber paint and a preparation method. Background technique [0002] Rubber is an elastomeric material. With the development of the national economy and the development of the rubber industry, the application of rubber and rubber products continues to expand. At the same time, people have higher and higher requirements for the comprehensive performance of rubber and rubber products, such as performance, protection performance, decoration performance and various special functions. In order to achieve the high-demand comprehensive performance of rubber and rubber products, it is necessary to apply a layer of coating to rubber and rubber products. At present, some rubber coating products have been reported in China. However, the comprehensive properties of domestic rubber coating products such as gloss, fullness, distin...
