▎ 摘　　要

NOVELTY - High wear-resistant and impact-resistant composite rubber comprises 100 pts. wt. nitrile rubber, 3-8 pts. wt. zinc oxide, 0.5-1 pts. wt. stearic acid, 1-2 pts. wt. sulfur, 0.5-1 pts. wt. accelerator, 15-25 pts. wt. carbon black, 5-10 pts. wt. biomass carbon microspheres and 1-5 pts. wt. modified biomass graphene oxide. The biomass carbon microspheres are carbon microspheres prepared from natural biological materials as carbon source. The modified biomass graphene oxide is prepared by modifying p-phenylenediamine using graphene oxide obtained from natural biological materials as carbon source. USE - Used as high wear-resistant and impact-resistant composite rubber. ADVANTAGE - The rubber: makes full use of crop straw; turns waste into treasure; and reduces environmental pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high wear-resistant and impact-resistant composite rubber, comprising preparing biomass carbon microspheres and modified biomass graphene oxide, adding modified biomass graphene oxide to deionized water, and ultrasonically dispersing for 0.5-1 hours, adding carbon black, biomass carbon microspheres and stearic acid, and ultrasonically dispersing for 0.5-1 hours, adding zinc oxide, sulfur and accelerator, and ultrasonically dispersing for 0.5-1 hours to obtain mixed solution, mixing the mixed solution with nitrile rubber, and ultrasonically dispersing for 0.5-1 hours to obtain stable composite emulsion, spray-drying and atomizing the composite emulsion to obtain composite liquid droplets, and removing moisture in the drying medium to obtain high-wear and impact-resistant composite rubber.
