技术领域
本发明涉及轮胎装配技术领域,具体涉及一种用于轮胎装配的润滑剂及其制备方法。
背景技术
轮胎是汽车行驶系中的重要部件,能起到支承车身、缓冲外界冲击的作用,实现与路面的接触并保证车辆的行驶性能。轮胎的装配过程,就是将各种车辆上的接地滚动圆环形弹性橡胶制品,在一定的压力和润滑条件下,安装在金属轮辋上。无论是原配轮胎或替换轮胎,虽然装配的操作简单,但是,装配质量对轮胎的寿命和车辆操纵性能影响很大,已经引起汽车企业的重视。
实心轮胎是与充气轮胎(空心轮胎)对应的一种轮胎,其胎体是实心的,不用帘线作骨架,不必充气,故不需内胎或气密层。为保证实心轮胎能顺利安装到位,减少与轮辋间的摩擦,安装时,轮胎的毂内和轮辋的外表面需喷、涂润滑剂,润滑剂通常用肥皂水、洗衣粉水等,但是肥皂水和洗衣粉水的针对性不强,因此需要一种实心轮胎的专用润滑剂。
