Description
技术领域
本发明涉及一种冷缩户外椎体料及其制备工艺。
背景技术
冷缩式电缆附件是利用弹性体材料(常用的有硅橡胶和乙丙橡胶)在工厂内注射硫化成型,衬以塑料螺旋支撑物构成各种电缆附件的部件。现场安装时,将这些预扩张件套在经过处理后的电缆末端或接头处,抽出内部支撑的塑料螺旋条(支撑物),压紧在电缆绝缘上而构成的电缆附件。因为它是在常温下靠弹性回缩力,而不是像热收缩电缆附件要用火加热收缩,故俗称冷收缩电缆附件。早期的冷收缩电缆终端头只是附加绝缘采用硅橡胶冷缩部件,电场处理仍采用应力锥型式或应力带绕包式。冷收缩式电缆附件具有体积小、操作方便、迅速、无需专用工具、适用范围宽和产品规格少等优点。与热收缩式电缆附件相比,不需用火加热,且在安装以后挪动或弯曲不会像热收缩式电缆附件那样出现附件内部层间脱开的危险(因为冷收缩式电缆附件靠弹性压紧力)。与预制式电缆附件相比,虽然都是靠弹性压紧力来保证内部界面特性,但是它不像预制式电缆附件那样与电缆截面一一对应,规格多。
但是,经研究发现,冷缩户外椎体料的优势特点很多,但还是存在一些欠缺,比如抗拉强度较低,塑性和韧性很差。能否研制抗拉强度强,塑性和韧性高,其使用范围更为广泛的冷缩户外椎体料,为本发明的技术要点。
