▎ 摘  要

NOVELTY - A graphene-modified rubber comprises 55-65 pts. wt. No. 3 smoked rubber, 35-45 pts. wt. styrene-butadiene rubber (SBR1502), 2.5-3.5 pts. wt. nano zinc oxide, 1.3-1.8 pts. wt. stearic acid, 1-1.5 pts. wt. N-isopropyl-N'-phenyl-P-phenylenediamine as antioxidant, 2-2.5 pts. wt. 1,2-dihydro-2,2,4-trimethylquinoline homopolymer, 1-2 pts. wt. 2-mercaptobenzimidazole (antioxidant MB), 45-55 pts. wt. Corax N220 (RTM: carbon black), 8-10 pts. wt. petroleum resin, 4-5 pts. wt. pine tar, 1.5-2 pts. wt. sulfur, 2-2.5 pts. wt. N-cyclohexyl-2-benzothiazole sulfonamide (accelerator CBS), 1-1.5 pts. wt. tetramethylthiuram disulfide, 1-1.5 pts. wt. 4,4'-dithiodimorpholine, 4-8 pts. wt. graphene predispersed emulsion butylbenzene rubber masterbatch, and 5-10 pts. wt. graphene predispersed natural rubber masterbatch. USE - Graphene-modified rubber for forming cover rubber of burning-resistant conveyor belt (claimed). ADVANTAGE - The graphene-modified rubber has excellent mechanical characteristics, and provides conveying belt having excellent burning resistance and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene-modified rubber.
