摘　　要：欧盟标准EN 50264对护套严苛的要求成为国内电缆企业进入机车电缆市场的技术门槛,为此研发了耐双油耐超低温低烟无卤橡胶护套料。配方生胶体系选择了朗盛EVM,随着VA含量的升高,EVM耐油性能也越来越好,耐低温性能变差;增塑剂TP-95对耐低温性能的改善最好,其次是DOS,DOA效果最差;增塑剂对提高耐低温性能有一定限度。The stringent requirements of the EU standard EN 50264 for jackets have become the technical threshold for domestic cable companies to enter the railway rolling stock cable market,for example the research and develop⁃ment of dual⁃oil resistant,ultra⁃low temperature,low⁃smoke and halogen⁃free rubber jacket materials.The formula chooses LANXESS EVM as the formula matrix resin.With the increase of VA content,EVM oil resistance is getting better,and the low temperature resistance becomes worse.TP-95 has the best improvement of low temperature resist⁃ance,followed by DOS and DOA with the worst effects,plasticizers have certain limits for improving low temperature resistance.
