一种耐甲醇燃料和汽油的塑胶组合物及其制备方法
摘要：
本发明提供了一种耐甲醇燃料和汽油的塑胶组合物，涉及车辆材料组合物及生产技术领域。本发明包括基础胶种、添加剂和防老剂，其重量配比为丁腈橡胶50～80份，聚氯乙烯(PVC)20～40份，氧化锌3～6份，硬脂酸1～3份，硫磺0.5～2份，抗臭氧蜡1～3份，邻苯二甲酸二仲辛酯0.5份，碳黑N774(N774)30～50份，碳黑N330(N330)20～30份，硫酸钡20份，液体丁腈5～7份，防老剂3～8份。本发明还提供了塑胶组合物的制备方法。本发明通过丁腈橡胶和聚氯乙烯共混制备塑胶组合物，具有优良的耐老化性能、耐油性、耐溶剂性和耐化学腐蚀性，且其中添加了氧化锌和防老剂等添加剂，在材料成型后能够形成对甲醇和汽油的耐腐蚀性。
摘要（英）：

The invention provides a plastic composition resistant to a methanol fuel and gasoline, and relates to the technical fields of vehicle material compositions and production. The composition includes abasic rubber variety, an additive and an anti-aging agent; and the composition concretely comprises the following materials in parts by weight: 50-80 parts of acrylonitrile-butadiene rubber, 20-40 parts of polyvinyl chloride (PVC), 3-6 parts of zinc oxide, 1-3 parts of stearic acid, 0.5-2 parts of sulphur, 1-3 parts of anti-ozone wax, 0.5 part of di-sec-octyl phthalate, 30-50 parts of carbon blackN774 (N774), 20-30 parts of carbon black N330 (N330), 20 parts of barium sulfate, 5-7 parts of liquid butyronitrile, and 3-8 parts of the anti-aging agent. The invention also provides a preparation method of the plastic composition. According to the method provided by the invention, the plastic composition is prepared by co-mixing of the acrylonitrile-butadiene rubber and the polyvinyl chloride,and has the advantages of excellent aging resistance, oil resistance, solvent resistance and chemical corrosion resistance, and additives such as the zinc oxide and the anti-aging agent are added, sothat the material can have corrosion resistance to methanol and gasoline after being shaped.
