环保型耐高低温耐油耐磨阻燃橡塑组合物
摘要：
本发明涉及一种橡塑组合物，其由丁腈橡胶粉40～50份，预塑聚氯乙烯粉30～40份，三元共聚尼龙5～15份，氢氧化镁5～15份，三氧化二锑5～15份以及加工助剂0.5～1.5份组成，其中：丁腈橡胶粉由丁腈橡胶90%～98%、硫化剂0.15%～1%、防老剂0.5%～3%、活化剂0.5%～3%、硫化促进剂0.3%～3%以及隔离剂0.5%～1.2%组成；预塑聚氯乙烯粉由聚氯乙烯树脂75%～90%，抗氧剂0.2%～1%，钙锌稳定剂1%～8%以及增塑剂邻苯二甲酸二异十三酯8%～18%组成。本发明组合物具有优良的耐高低温、耐油、耐磨以及阻燃性能，且未使用不环保的原料，特别适于用作电线电缆用护套料。
摘要（英）：

The invention relates to a rubber plastic composition, which is made from the following components of: by weight, 40-50 parts of an acrylonitrile butadiene rubber powder, 30-40 parts of a preplastic polrvinyl chloride powder, 5-15 parts of ternary copolymerized polyamide, 5-15 parts of magnesium hydroxide, 5-15 parts of antimonous oxide and 0.5-1.5 parts of a processing aid. The acrylonitrile butadiene rubber powder is made from components of: by weight, 90-98% of nitrile rubber, 0.15-1% of a vulcanizator, 0.5-3% of an anti-aging agent, 0.5-3% of an activating agent, 0.3-3% of a vulcanizationaccelerator and 0.5-1.2% of an isolating agent. The preplastic polrvinyl chloride powder is made from components of: by weight, 75-90% of a PVC resin, 0.2-1% of an antioxidant, 1-8% of a calcium zincstabilizer and 8-18% of a plasticizer DITDP diisotridecyl phthalate. The composition provided by the invention has excellent high and low temperature resistance, oil resistance, wear resistant and fire retardant performance. In addition, raw materials which are not environmentally friendly are not used. Therefore, the invention is especially applicable to be used as a sheathing compound for wire and cable.
