PTFE, 20-35 pts. wt. coal, 15-30 pts. wt. modified graphene, 5-10 pts. wt. alumina, 2-6 pts. wt. magnesium stearate, 2-6 pts. wt. zinc methacrylate, 1.5-3 pts. wt. zinc oxide, 2-5 pts. wt. stearic acid, 0.2-0.6 pt. wt. sulfur, 1-2.5 pts. wt. phenolic resin, 1-2 pts. wt. benzoyl peroxide, 2-5 pts. wt. rosin, 2-7 pts. wt. dioctyl phosphate, 3-6 pts. wt. anti-aging agent, and 3-5 pts. wt. accelerating agent. USE - Heat-resistant chemical medicine laboratory table pad. ADVANTAGE - The pad has high strength, heat resistance, good performance and good wear resisting property. DETAILED DESCRIPTION - Heat-resistant chemical medicine laboratory table pad comprises 50-70 pts. wt. brominated butyl rubber, 10-30 pts. wt. epoxidized natural rubber, 10-25 pts. wt. PTFE, 20-35 pts. wt. coal, 15-30 pts. wt. modified graphene, 5-10 pts. wt. alumina, 2-6 pts. wt. magnesium stearate, 2-6 pts. wt. zinc methacrylate, 1.5-3 pts. wt. zinc oxide, 2-5 pts. wt. stearic acid, 0.2-0.6 pt. wt. sulfur, 1-2.5 pts. wt. phenolic resin, 1-2 pts. wt. benzoyl peroxide, 2-5 pts. wt. rosin, 2-7 pts. wt. dioctyl phosphate, 3-6 pts. wt. anti-aging agent, and 3-5 pts. wt. accelerating agent. The modified graphene is prepared by taking tetraisopropyl titanate, N,N-diethyl hydroxylamine, dioctyl phosphate, methacrylic acid and alpha -hydroxy acid, mixing under nitrogen protection, heating and reacting, washing and distilling to get modifier; and adding ethanol to reaction vessel, adjusting pH, adding modifying agent, stirring uniformly, adding graphene oxide, stirring uniformly, heating, adding acetone, suction filtering, washing, and drying.
