NOVELTY - An engineering retreaded tire tread comprises 80-120 pts. wt. base rubber, 4-7 pts. wt. white carbon black, 30-40 pts. wt. carbon black, 3.5-18.9 pts. wt. modified graphene oxide, 1-3 pts. wt. accelerating agent, 1-3 pts. wt. vulcanizing agent, 2-4 pts. wt. antioxidant, 1-2 pts. wt. additive, 1-3 pts. wt. stearic acid, 3-5 pts. wt. zinc oxide, 1-3 pts. wt. aromatic hydrocarbon oil, 0.4-0.6 pt. wt. anti-ozone wax and 2-4 pts. wt. tackifier. USE - Engineering retreaded tire tread. ADVANTAGE - The engineering retreaded tire tread has excellent crack resistance, puncture resistance, and adhesiveness of graphene oxide-containing tread layer and old carcass layer, and reduced delamination of tread and carcass of retreaded tire, and can be prepared by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of tread, which involves mixing base rubber and binder, adding carbon black, modified graphene oxide, white carbon black and antioxidant, mixing, adding remaining raw materials, mixing, vulcanizing, and cooling.
