Butyronitrile rubber-based composite material for cushion pad of pneumatic nailing gun and preparation method of butyronitrile rubber-based composite material

The invention discloses a butyronitrile rubber-based composite material for a pneumatic nailing gun buffer pad and a preparation method thereof, and belongs to the field of rubber matching and vulcanization. The composite material comprises the following raw materials: nitrile rubber, carbon black, a carbon nanotube pre-dispersion, a reactive plasticizer, zinc oxide, a vulcanizing agent, an anti-aging agent, stearic acid, microcrystalline wax and dioctyl sebacate. The specific method comprises the following steps: mixing nitrile rubber, carbon black, a carbon nanotube pre-dispersion, a reactive plasticizer, zinc oxide, an anti-aging agent, stearic acid, microcrystalline wax and dioctyl sebacate, banburying, and then adding a vulcanizing agent for open milling to obtain a rubber compound; and performing, and finally vulcanizing to obtain the butyronitrile rubber-based composite material. The material prepared by the invention has relatively high modulus, definite elongation, tearing strength and high temperatu
