Rubber and plastic blending composition for air gun projectile and preparation method of rubber and plastic projectile

The invention discloses a rubber and plastic blending composition for an air gun pill. The composition comprises 100 parts of a rubber and plastic blending material, 5-50 parts of a plasticizer, 0.5-5 parts of paraffin, 10-60 parts of an inorganic filler and 0.5-3 parts of an antioxidant, and 0.1-0.3 part of a vulcanizing agent. The air gun projectile adopting the rubber and plastic blending composition comprises a shell and an internal filler, the shell consists of an upper part and a lower part and is made of a rubber and plastic blended composition; and the internal filler is barium sulfate powder or calcium carbonate powder. The air gun projectile prepared through the method has low lethality, and the flight stability and hit accuracy of the projectile are improved. 本发明公开了一种用于气枪弹丸的橡塑共混组合物。该组合物包括橡塑共混料100份、增塑剂5-50份、石蜡0.5-5份、无机填料10-60份、抗氧剂0.5-3份；硫化剂0.1-0.3份。采用该橡塑共混组合物的气枪弹丸包括壳体和内部填充物；所述壳体由上、下两部分组成，材料为橡塑共混组合物；所述内部填充物为硫酸钡粉料或碳酸钙粉料。本发明所制备的气枪弹丸具有较低的杀伤力，提高了弹丸的飞行稳定性和命中精准性。
