Description
技术领域
本发明涉及管材生产技术领域,特别涉及一种碳纤维增强聚丙烯电缆保护管的制备方法。
背景技术
电缆保护管是电缆结构中的重要组成,是电缆的最外层,电缆保护管是为了防止电缆受到损伤,电缆保护管主要安装在通讯电缆与电力线交叉的地段,防止电力线发生断线造成短路事故。电缆在输电过程中,会产生热量,导致电缆线温度升高,影响电的正常输送,但是,在聚丙烯电缆保护管材料中,为了提高电缆线的导热性能,通常会加入金属材料,金属材料具有优秀的导热性能,但也具有一定的导电性,虽然电缆保护管的内部还设有绝缘层,但绝缘层若受到局部破坏,具有导电性的电缆保护管则起不到绝缘防护的作用,因此亟需研发一种绝缘导热的电缆保护管。
发明内容
本发明所要解决的技术问题是:提供一种同时具备优良导热性、绝缘性的碳纤维增强聚丙烯电缆保护管的制备方法。
为了解决上述技术问题,本发明采用的技术方案为:
一种碳纤维增强聚丙烯电缆保护管的制备方法,包括以下步骤:
步骤1:将2-3份碳纤维投入过氧化氢溶液中,进行氧化处理,将经过氧化处理的碳纤维与0.1-0.2份笼型聚倍半硅氧烷、0.1-0.2份过氧化物交联剂和溶剂混合,得到导热助剂;
步骤2:将步骤1制得的导热助剂与80-90份聚合度为2000-2500的聚丙烯、3-5份甲基丙烯酸、3-4份增韧剂、10-15份丙烯酸缩水甘油酯和15-17份填料共混,于双螺杆挤出机挤出造粒;
步骤3:将步骤2制得的粒料与20-30份聚合度为3000-3500的聚丙烯共混,与管材挤出机中,通过管材挤出机挤出制得电缆保护管。
本发明的有益效果在于:
1、导热助剂的形态和添加量一定程度上影响了聚丙烯的结晶性能和其他助剂的作用效果,碳纤维的改性中,通过将笼型聚倍半硅氧烷结合在碳纤维皮层上,从而改变碳纤维皮层的空间形态,使碳纤维皮层绝缘化,提高碳纤维电阻率,降低碳纤维的介电常数,从而降低其导电能力,通过在碳纤维外表面上引入和聚丙烯相匹配的单一官能团,碳纤维自身的强度不变,但表面的粗糙度增大,大大提高其与聚丙烯的界面粘接性能,通过在配方中加入丙烯酸缩水甘油酯和甲基丙烯酸,使聚丙烯进行接枝改性,使改性碳纤维与聚合度为2000-2500的聚丙烯具有更好的相容性;
