Description
技术领域
本发明涉及绝缘材料技术领域，具体为耐核环境电缆绝缘材料。
背景技术
核电站核岛电缆要求电缆护套材料必须具有优异的耐热老化性能、耐辐射老化性能、阻燃性能、耐湿热性能等。目前常用的绝缘材料为聚乙烯、交联聚烯烃与乙丙材料。在核环境下，正常运行的电缆须要经受γ、β射线的辐照，并且具备在事故情况下的保持电缆正常运行的要求。由于一般聚合物在辐照作用下产生电高或激发等反应后，进一步发生以下化学反应：大分子间出辐照引发的交联反应、辐照引发的降解反应、氧化反应、产生气体产物、其他如异构化等，这些反应在不同的反应速率下发生的程度不同，最终的结果是聚合物材料的分子量愈来愈小，甚至失去聚合物的性质。因此，对于在核环境中运行的电缆料，需要具有优异耐核辐射的性能。
发明内容
为了解决上述问题，本发明提供了耐核环境电缆绝缘材料。
本发明是通过以下技术方案实现的：
耐核环境电缆绝缘材料，其原料构成为：
所述阻燃剂为硅橡胶阻燃剂。
