▎ 摘  要

NOVELTY - Modified rubber graphene comprises 80-100 pts. wt. natural rubber, 0-20 pts. wt. synthetic rubber, 0.1-6 pts. wt. graphene dispersion, 10-60 pts. wt. reinforcing agent, 0.5-6 pts. wt. coupling agent, 1-8 pts. wt. active agent, 1-8 pts. wt. anti-aging agent, 0.5-3 pts. wt. sulfur, 0.5-5 pts. wt. accelerator, 0.5-2 pts. wt. anti-reversion agent, and 0.1-0.3 pts. wt. scorch retarder. The graphene dispersion comprises graphene and a dispersant in a weight ratio of 1:0.05-1. USE - The graphene modified rubber composition is useful for manufacturing graphene tread rubber, which is used for loading tire, engineering tire, and airplane tire. ADVANTAGE - The rubber composition has excellent graphene characteristics, overcomes the problem that the existing graphene/rubber composite material is graphene to disperse in the rubber matrix, the problem of bad interface effect, providing a graphene tread rubber graphene dispersion property, high strength, high abrasion resistance and preparation method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a graphene tread rubber; method for manufacturing the graphene tread rubber.
