Description

一种光伏电缆用无卤阻燃护套料
技术领域
本发明涉及一种电缆材料,尤其是一种光伏电缆用无卤阻燃护套料,属于电缆技术领域。
背景技术
随着电线电缆工业的发展，人们对线缆产品提出了更高更严格的性能要求。电缆用绝缘料一般要求必须具有优良的耐长期热老化性能、耐辐照、电气性能稳定、阻燃性能及绝缘性能优等特点。目前常用的电缆用绝缘料的基料为聚乙烯、聚氯乙烯、乙丙橡胶等材料，但是，这些基料的主要缺点是容易着火燃烧引起火灾。而采用含卤素的阻燃聚氯乙烯，虽然具有一定的阻燃作用，但是，与采用聚烯烃等无卤基料相比，采用聚氯乙烯基料在燃烧时会产生有毒的氯化氢气体及大量烟雾，使人中毒和窒息，妨碍人们从火灾中撤离和灭火工作的进行，造成了生命和财产的损失。
核电站用电缆要求电缆护套料必须具有优良的电气性能、耐辐照性、无卤低烟低毒及阻燃性能好和使用寿命长的特性。目前常用的核电站用电缆护套料为EVA、氯丁胶、氯磺化聚乙烯等材料。然而，现有核电站电缆护套料基本上是按照第二代核电站电缆的性能要求设计，其耐热寿命为90℃/40年和耐60Co-γ射线累积剂量850kGy/70℃；同时，电缆护套材料还具有良好的物理机械性能、无卤低烟低毒性、高阻燃性、绝缘性等性能。
然而，随着核电领域的技术发展，目前已经出现了第三代核电站电缆用护套料，其要求电缆护套料的热寿命要求达到90℃/60年以上和耐6 0 Co-γ射线累积剂量要达到2600kGy/70℃以上，比第二代核电站电缆用护套料的要求明显提高。因此，怎样改进材料配方，使护套料的热寿命和耐辐照性能达到第三代核电站电缆的要求，是亟待解决的技术问题。
发明内容
本发明的目的是针对上述现有技术的不足，提供一种光伏电缆用无卤阻燃护套料，该材料具有耐热、耐油、耐化学腐蚀性能，可延长电缆的使用寿命，大量节省导体材料和绝缘材料，使电缆轻便柔软。
本发明的目的是通过以下技术方案实现的：一种光伏电缆用无卤阻燃护套料，其特征是，包括以下重量份的各组份制备而成：硅橡胶230-250 份、氯磺化聚乙烯橡胶120-135份、氧化镁11-56份、二氯化铁15-38份、有乳聚丁苯橡胶30-45 份、炭黑28-32 份、硫化剂13-17 份、防老剂12-25份、促进剂12-18份、低分子聚乙烯石蜡22-39份、硬脂酸14-18份、氧化锌14-27份、硅烷偶联剂11-23份、无水乙醇15-25份、硫化剂12-18份。
所述促进剂为N- 叔丁基-2- 苯并噻唑次磺酰胺、二硫化四苄基秋兰姆中的一种或者两种的组合。
所述硫化剂为过氧化二异丙苯、双（叔丁过氧基）二异丙苯。
本发明材料耐紫外线辐射性能优异，柔软性好，且具有优良的物理机械性能和阻燃性能，经久耐用，为耐紫外辐射电源线护套的开发奠定了原料基础，且符合UL和欧盟ROHS要求，环保完全，解决了耐紫外辐射性能、物理机械性能、环保性能等难以全面达到要求的技术难题，具有巨大的社会效益和经济效益。
本发明能够实现较好的阻燃效果，且通过各成分之间的协同作用，降低了绝缘料的吸水性能，实现高阻燃效果的同时实现高电绝缘效果且在浸湿条件下绝缘料仍具有较好的电绝缘稳定性，，提高了绝缘料的综合性能，且还具有消烟的作用，实现低烟的效果,实现降低生产成本的作用，有利于工业化生产的目的。
