中文摘要:
      本研究耐辐射无卤阻燃绝缘EPDM电缆胶料的主要配合为:生胶为乙烯含量较高的1,4-己二烯型电绝缘级EPDM(100份);阻燃剂为氢氧化铝/氢氧化镁/三氧化二锑并用体系(95~100份),其中氢氧化铝和氢氧化镁用硬脂酸锌进行表面处理;补强填充剂为煅烧陶土、LEE白滑粉、PY-Ⅱ型水白云母粉和钛白粉并用体系(105~115份);硫化剂为2,5-二甲基-2,5-二(叔丁基过氧化)己烷(4~5份),共硫化剂为三羟甲基丙烷三甲基丙烯酸酯和N,N′-间亚苯基双马来酰亚胺并用体系(1.6~1.8份)。胶料和成品的物理机械性能、介电性能、阻燃性能和耐环境性能(耐热性、耐蒸汽性和耐辐射性)达到IEC502(1994)和IEC18A(1981)(CO)标准。
英文摘要:
      A radiation resistant,halogenfree flame retardant EPDM insulating compound for cable has been developed. The formula is as follows:electric insulating grade EPDM with high ethylene and with 1,4-hexadiene as the third monomer 100 phr;aluminium hydroxide(treated with zinc stearate on its surface)/magnesium hydroxide(treated with zinc stearate on its surface)/antimony trioxide flame retardant agent 90~100 phr;calcined clay/LEE white slippery powder/PY-Ⅱ water-white mica powder/titanium white powder 105~115 phr;2,5-dimethyl-2,5-di(tert-butyl peroxy)hexane 4~5 phr;trimethylol propane trimethacrylate/N,N′-m-phelylene bismaleimide 1.6~1.8 phr. The physical properties,dielectric property,flame retardance,heat resistance,steam resistance and radiation resistance of the compound and the finished product are in accordance with the IEC 502(1994)and IEC 18A(1981)standards.
