▎ 摘  要

NOVELTY - Rubber coating comprises 14-20 pts. wt. rubber, 70-75 pts. wt. solvent, 1-2 pts. wt. epoxy monomer, 1-2 pts. wt. isocyanate monomer, 1-2 pts. wt. polyol monomer, 1-2 pts. wt. curing agent, 3-5 pts. wt. reinforcing agent and 0.6 pt. wt. other additive agents. USE - As rubber coating. ADVANTAGE - The rubber coating has high weather resistance, protects the rubber to achieve high temperature resistance, UV resistance and other weather resistance, prolongs the service life, and has stable storage properties, low viscosity and simple operation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the rubber coating involving (i) adding rubber particles to dry solvent in batches, adding the reinforcing agent, heating to a slight boiling of the solvent, and stirring to dissolve the rubber, filtering through 100 mesh sieve, and cooling to normal temperature, (ii) sequentially adding epoxy monomer, isocyanate monomer, polyol monomer, curing agent and other additives under the protection of nitrogen to the rubber solution, and stirring at 200-300 rpm for 30-40 minutes and (iii) adding the product obtained into the packaging tank, evacuating and replacing with nitrogen, replacing with argon, and sealing to obtain the finished product.
