Abstract

本发明提供一种用于制造热缩套管的热缩纤维 增强复合材料的成型工艺，采用层压方法，在一定温 度和压力下将增强纤维织物层压复合于聚乙烯中，制 成热缩纤维增强复合材料，用该材料制成的热缩套管 适于气压维护电缆接头密封。

Description

本发明提供一种用于制造热缩套管的纤维增强复合材料的成型工艺。用该种工艺加工复合材料制成的热缩套管具有很好的机械性能和密封性能，适用于气压维护型电缆接头的密封。
用于通讯电缆接头密封的热缩套管是利用聚合物的“记忆效应”加热使其径向尺寸收缩于电缆接头上达到密封目的。目前该种热缩套管增均为单纯的聚乙烯制成，其机械性能、耐候性乃至密封性均较差，不能用于气压维护电缆接头的密封。国外于八十年代中期在该种热缩套管中加入增强纤维，制成强力纤维热缩套管，用于电缆气压维护，达到密封保气目的。但其产品中的纤维层和外层材料复合不牢，加热收缩时易分层。
本发明提出了一种新的成型工艺方法，用该方法生产的热缩纤维增强材料为一体化结构，强度性能大为提高。
本发明采用的是将纤维层置于两层塑料之间用层压方法成型的工艺：将增强纤维置两层聚乙烯薄片之间，织物的厚度为0.3～0.6毫米，聚烯烃层厚度为0.3～0.8毫米，层压时温度为120℃～200℃，压力为30～60kg/cm2，时间40～60分钟。冷却后取出层压产品。
实际证明采用该工艺制成的热缩纤维增强材料，上、下两层聚烯烃已连成一体无法分开，即增强纤维织物已完全复合于聚烯烃中，形成一体化结构。用此种材料制成的热收缩套管，强度非常好，特别适于大对数充气电缆的接头密封，能长期耐压密封。
