NOVELTY - Rubber comprises 100 pts. wt. raw rubber, 1-4 pts. wt. stearic acid, 2-6 pts. wt. accelerator, 0.5-3 pts. wt. antioxidant, 15-60 of carbon black, 5-20 pts. wt. nano-silicon dioxide, 10-40 pts. wt. graphene, 1-5 pts. wt. silane-coupling agent, 1-5 pts. wt. super-tackifying resin, 0.5-3 pts. wt. scorch retarder PVI, 1-5 pts. wt. flame retardant and 0.5-3 pts. wt. light stabilizer. USE - Rubber used for high-speed crawler belt. ADVANTAGE - The rubber meets the requirements of different users for comprehensive performance of rubber crawlers at high speeds. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the rubber, involving (a) crushing, drying, sieving and uniformly stirring accelerator, stearic acid and scorching agent, (b) weighing raw rubber and nano-silicon dioxide, and sequentially adding raw rubber and nano-silicon dioxide to open mill for plastication, (c) weighing to-be-used ingredients, and adding ingredients in open mill for secondary plastication, (d) adding graphene, silane coupling agent, flame retardant and light stabilizer, and sequentially adding graphene, silane coupling agent, flame retardant and light stabilizer to open mill for uniformly mixing, (e) adding carbon black and antioxidant, and sequentially adding carbon black and anti-aging agent to open mill for secondary mixing, (f) adding super-tackifying resin to open mill for final mixing, (g) packaging rubber material in open mill for multiple times, uniformly mixing the raw materials, (h) placing rubber material in mold for molding, (g) placing rubber material on vulcanizing machine to be vulcanized to obtain vulcanized rubber.
