Description

一种润滑液的制备方法
技术领域
本发明属于润滑领域，特别涉及一种润滑液的制备方法。
背景技术
一般地，润滑液用在各种加工过程中，以降低接触表面的摩擦阻力、减缓其磨损，主要起润滑、冷却、防锈、清洁等作用。特别地，在汽车轮胎的装配过程中，当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，安装在金属轮辋上时，需要在轮胎胎圈部位涂抹一层润滑液，以减少装胎阻力、初装充气压力及对轮胎的损坏，不影响轮胎的动平衡和气密性。由于使用的润滑液同时与铝合金轮辋和橡胶轮胎接触，这就要求润滑液在起到润滑减磨作用的基础上，还应具备较好的铝合金防锈性和橡胶相容性。在汽车运行过程中，对于不同温度下润滑液发挥稳定的作用是较为关键的考察指标。目前现有的润滑液中，在温差相差较大的使用条件下，润滑液的润滑性能也会随之发生较为明显的变化，这样就导致了润滑液在使用过程中的不稳定性。
发明内容
本发明的目的在于为了克服以上现有技术的不足而提供一种润滑液的制备方法，提升润滑液的润滑效果以及不同温度下的使用稳定性。
本发明的技术方案如下：
一种润滑液的制备方法，包括以下步骤：

步骤2，将聚乙烯吡咯烷酮0.5-0.8份，三乙醇胺柠檬酸酯1-3份，硼酸酯1-2份，脂肪醇聚氧乙烯醚2-4份，卵磷脂3-6份，单甘脂1-3份加入到20-30份基础油中，搅拌混合，得到混合液二；
步骤3，将混合液一和混合液二混合，加热搅拌混合，然后于高压均质机中进行均质，得到润滑液。
所述的润滑液的制备方法，步骤1中聚乙二醇为聚乙二醇800。
所述的润滑液的制备方法，步骤1中消泡剂为硅油消泡剂。
所述的润滑液的制备方法，步骤1中表面活性剂为十二烷基苯磺酸钠。
所述的润滑液的制备方法，步骤2中的基础油为酯类基础油。
所述的润滑液的制备方法，步骤3中加热搅拌混合的加热温度为40-50℃。
所述的润滑液的制备方法，步骤3中均质压力为30-40MPa。
本发明结合了水性润滑液与油性润滑液的特点，采取了乳化的方式，使得乳化液的性能更优。本发明提供的润滑液具有良好的润滑性能，其中运动粘度在不同温度下的变化不明显，具有良好的温差范围内的稳定性，同时具有良好的粘度系数以及较低的挥发物含量。
