Example Embodiment
[0031] Example 1
[0032] 100 parts of ethylene propylene rubber and 15 parts of polyethylene powder are banned. And put in nano-scale zinc oxide, stearic acid, anti-hydrophobic agent red lead powder (coating grade), paraffin oil 2280, alkane coupling agent A-172, silane modified calcined clay, and peroxide vulcanizing agent for mixing. After mixing, move the mixed rubber to an open mill for reprocessing. After the rubber is smelted, it is filtered. After filtering the glue, move to the forming machine for rolling and slicing.
