▎ 摘  要

NOVELTY - Composite rubber based on paper-like graphene microspheres, comprises 100 pts. wt. rubber, 0.1-10 pts. wt. spitball graphene microsphere, 0.5-5 pts. wt. vulcanizing agent, 3-10 pts. wt. vulcanization accelerator and 5-20 pts. wt. other auxiliary agent. The paper-like graphene microspheres are wrinkled to obtain single layer of graphene sheets, where diameter of microsphere is 500nanometer-5 microns, density is 0.2-0.4 grama/cubic centimeter. The carbon/oxygen ratio is 20-60 and specific surface area is less than 200 square meter/gram. USE - Graphene-modified based on spitball composite rubber. ADVANTAGE - The graphene-modified based on spitball composite rubber has excellent mechanical strength, wear resistance, elasticity and flame retardancy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite rubber based on paper-like graphene microspheres, which involves: (A) paper-like graphene microspheres, vulcanizing agent and other auxiliary agent; (B) adding reaction mixture into mixer and stirring for 10 to 30 minutes at 40-90 degrees C; (C) allowing to stand for 5 to 8 hours; (D) placing standing mixture and vulcanizing agent at 40-9 degrees C; and (E) vulcanizing reaction mixture in plate vulcanizing machine at 150-180 degrees C for 10-40 minutes.
