摘要

用硅橡胶、三元乙丙橡胶、高密度聚乙烯的共混物加入低卤阻燃剂制备耐高温的绝缘材料。该体系经γ射线辐射后，由于辐射交联，其耐高温性能提高，可在135℃下长期使用，而且力学强度改善，阻然性好，氧指数达到32。研究了不同体系的阻燃性能及耐高温性能都大幅度提高的原因，表明阻燃剂的加入，不仅能阻燃，而且改善了材料的热老化性能。硅橡胶对材料的热老化和复合阻燃效应都有很大的贡献。辐射使HDPE与硅橡胶的界面粘结有明显的增强。

Abstract

Radiation-crosslinking improves a number of essential properties of polymers, so the high -temperature-resistance of polyethylene(PE) was increased by irradiation. The national products of High -density-polyethylene (HDPE), crosslinking promoters, flame-retardant, antioxidants, Si rubber, and Ethylene-propylene-monomer(EPDM) were used as cable insulation. After -irradiation, thermal-endurance can get above 135, and high flame retardacy was firmed, Oxygen index can get above 32 by crosslinking.
