1.本发明矿用电缆橡皮护套材料及其制备工艺，其采用氯化聚乙烯20～30份和氯丁橡胶5～15份组合作基料，通过添加氧化镁2～4份、氧化锌0.3～0.8份、二盐基硫酸铅0.3～1.5份、三盐基硫酸铅0.2～1.2份、70#氯化石蜡2～7份、炭黑10～18份、三氧化二锑2～5份、沉淀法白炭黑3～6份、改性煅烧纳米陶土4～9份、γ-巯丙基三乙氧基硅烷0.2～0.4份、三羟甲 基丙烷三甲基丙烯酸酯0.8～1.2份、环氧大豆油1～3份、三烯丙基异三聚氰酸酯0.7～1.2份协同作用来提高橡胶护套料的拉伸强度、断裂伸长率和耐磨性能，从而使得拉伸强度大于12Mpa，断裂伸长率大于350％；三羟甲基丙烷三甲基丙烯酸酯和三烯丙基异三聚氰酸酯共同使用可以明显提高抗撕强度，护套材料具有较佳的物理机械性能，制备工艺简单，可操作性强；其次，氯化聚乙烯和氯丁橡胶并用同时采用偏苯三酸三辛酯和环氧大豆油进行复配，护套材料有着良好的耐油性能。
2.本发明矿用电缆橡皮护套材料及其制备工艺，其进一步添加N，N-二甲基苯胺0.2～0.4份、4,4’-二辛基二苯胺0.2～0.5份配合偏苯三酸三辛酯3～6份、N-N-苯基对苯二胺0.3～0.8份、RD0.2～0.4份与组合基料氯化聚乙烯、氯丁橡胶，组合协同作用改善了护套的老化性能和耐磨性能，老化温度可以到达135℃，具有良好的耐候性能，也改善了材料的体积电阻率(大于1011Ω.m)。
3.本发明矿用电缆橡皮护套材料及其制备工艺，其进一步添加水滑石10～20份、聚磷酸铵11～15份配合70#氯化石蜡、炭黑、三氧化二锑，无机阻燃剂水滑石、聚磷酸铵和炭黑复配，燃烧时相互作用，降低发烟量；70#氯化石蜡和三氧化二锑复配，氧指数可以显著提高，此种电缆橡皮护套材料氧指数可以达到42％以上，且降低了燃烧时发烟量。
