NOVELTY - A battery cover comprises 120-160 pts. wt. natural rubber, 20-30 pts. wt. butadiene rubber raw rubber, 3-5 pts. wt. mica powder, 10-15 pts. wt. clay, 1-3 pts. wt. bis(pentamethylene)thiuram tetrasulfide, 0.5-1.5 pts. wt. dicumyl peroxide, 2-10 pts. wt. accelerator, 5-10 pts. wt. softener, 5-8 pts. wt. graphene, 5-8 pts. wt. dioctyl phthalate, 3-8 pts. wt. glass fiber, 5-7 pts. wt. alumina hollow microspheres, 3-10 pts. wt. magnesium oxide, 1-3 pts. wt. plasticizer, 2-4 pts. wt. coupling agent, 1-3 pts. wt. surfactant, 1-1.5 pts. wt. antioxidant, 3-5 pts. wt. initiator, 1-3 pts. wt. paraffin oil, and 1-3 pts. wt. stearic acid. USE - Battery cover of car. ADVANTAGE - The battery cover has simple preparation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of battery cover of car, which involves (1) adding corresponding weight of natural rubber to a cutting machine for cutting, heating the temperature of the plasticizer to 190-220 degrees C, adding the cut natural rubber to the temperature after the temperature is reached in the plastic mixer, adding the butadiene rubber raw rubber to the plasticizer, and masticating for 3-7 minutes to obtain a rubber glue A, adding the rubberized rubber glue A to the mixer, sequentially adding mica powder, clay, bis(pentamethylene)thiuram tetrasulfide, dicumyl peroxide, accelerator, softener, plasticizer, coupling agent, surfactant, antioxidant , initiator, paraffin oil, stearic acid, high speed mixing for 2-6 minutes, adding graphene, dioctyl phthalate, glass fiber, alumina hollow microspheres and magnesium oxide to continue high-speed mixing 2-4 minutes to obtain rubber material B, (3) pouring rubber material B into the production mold of the automobile battery cover, and holding to stand for 1-3 hours to obtain a semi-finished product C, (4) trimming the semi-finished product C and checking into the warehouse.
