辐射交联150℃阻燃聚烯烃热收缩材料的研制

摘要

The composition，preparing technology and properties of radiation crosslinked，heat resistant and flame resistant polyolefin heat shrinkable material were studied，and the polyolefin heat shrinkable material with heat resistance up to 150℃，the OI of which was 30，was prepared．The prepared material could be used at 150℃ for a long time，and was characterized by high temperature resistance，good mechanical and elecrical properties and flame resistance，and could be widely applied to aircrafts，architecture，atuomobiles，military wehicle and cable insulation．%本文介绍了一种辐射交联150℃阻燃聚烯烃热收缩材料的配方研究，制备工艺及性能，通过确定聚烯烃热收缩材料制备工艺，挤出温度、辐照剂量等，制备出耐温达150℃，氧指数达30的热收缩材料，此材料可在150℃温度下长期使用，具有耐高温、机械、电性能优异、阻燃性能好，可广泛使用在航天、航空、汽车、军工等线缆的绝缘保护。
