Polyolefin elastomer modified silicon rubber composite material used for anti-sticking nontoxic packing washer of glass mouth cup cover and preparation method

The invention discloses a polyolefin elastomer modified silicon rubber composite material used for the anti-sticking nontoxic packing washer of a glass mouth cup cover and a preparation method. The polyolefin elastomer modified silicon rubber composite material comprises the following raw material ingredients in parts by weight: 50-90 parts of methyl vinylsiloxane rubber, 10-50 parts of polyolefin elastomer, 5-20 parts of filler, 5-10 parts of compatibilizer, 0.5-2 parts of surfactant, 0.5-2 parts of antioxidant and 0.5-2 parts of crosslinking agent. The polyolefin elastomer modified silicon rubber composite material disclosed by the invention has the characteristics of low surface polarity, high elastic recovery, non sticking with glass, simple preparation method and the like, and can be used for manufacturing a sealing element between metal and glass, a glassware packing washer, a glass buffer gasket and a rubber plug. The prepared packing washer has the advantages of good sealing performance, good conforma
