NOVELTY - Peelable semi-conductive shielding rubber comprises 80-95 pts. wt. ethylene vinyl acetate rubber, 5-20 pts. wt. ethylene propylene rubber, 0.5-2 pts. wt. graphene, 10-30 pts. wt. conductive carbon black, 5-10 pts. wt. plasticizer, 1-2 pts. wt. anti-aging agent and 2-4 pts. wt. vulcanizing agent. USE - The peelable semi-conductive shielding rubber is useful for rubber cable (claimed). ADVANTAGE - The shielding rubber has stable and conductive performance, and it is easy to process and easy to peel. DETAILED DESCRIPTION - Preparing strippable semiconductive shielding rubber for rubber cable comprises (1) weighing the related material, adding ethylene vinyl acetate rubber dividing into two times for low temperature plastication, (2) plasticating the ethylene propylene rubber on the open mill, uniformly adding the graphene, adding graphene and the whole material mixed glue the open mill keeps a cutting direction, adjusting the open mill thickness to not greater than 0.1mm, thinning for many times to obtain graphene ethylene propylene rubber mixture, the temperature of the whole mixing process is not greater than 120 degrees C, (3) mixing by adding conductive carbon black to the ethylene vinyl acetate rubber obtained in step (1), adding plasticizer at the same time, adding antioxidant and vulcanizing agent in sequence after mixing, add the product obtained in step (2) after mixing graphene ethylene propylene rubber mixture, the shear direction of the graphene ethylene propylene rubber mixture is the same as that in step (2), adding graphene ethylene propylene rubber mixture, the mixed rubber is on the open mill with a thickness of not greater than 0.1 mm along the same and performing thin passes in the shear direction many times, and finally discharge the film in the same direction and the temperature during the entire mixing process does not exceed 100 degrees C.
