Description

一种轮胎防刺割层用芳纶织物的生产方法
技术领域
本发明属于轮胎防护技术领域,具体涉及一种轮胎防刺割层用芳纶织物的生产方法。
背景技术
对位芳纶最突出的性能是其高强度、高模量和出色的耐热性,同时,它还具有适当的韧性可供纺织加工。标准PPTA芳纶的重量比拉伸强度是钢丝的6倍,玻纤的3倍,高强尼龙工业丝的2倍;其拉伸模量是钢丝的3倍,玻纤的2倍,高强尼龙工业丝的10倍;在200℃下经历100hr,仍能保持原强度的75%,在160℃下经历500hr,仍能保持原强度的95%。据此,对位芳纶大多被用作轻质、耐热的纺织结构材料或复合结构增强材料。
CN 200410035689.8公开一种混捻芳纶浸胶帘子布的生产方法,其选用高性能纤维—芳纶丝和耐温性能好、强度较高的涤纶工业长丝或锦纶66工业长丝作为经向材料,采用棉纱为纬向材料,生产的浸胶混捻芳纶帘子布,表面摩擦系数大、粘合性能突出,该芳纶帘子布虽可作为轮胎增强材料使用,但只有单向的增强作用,不能实现多轴向耐切割防护。
目前通过对位芳纶纤维进行织布、浸胶处理,制成轮胎用芳纶机织布,使芳纶机织布具有一定的耐切割功能,但由于织物孔隙较小,橡胶原料不能穿透该空隙,与橡胶粘合力差;芳纶机织布其面密度较大,应力集中,是适合用作子午胎骨架材料,不适合用作轮胎防刺割层。
