Description

一种高粘度指数润滑油的制备方法
技术领域
本发明属于润滑油技术领域，特别涉及一种高粘度指数润滑油的制备方法。
背景技术
为了减少两个彼此接触、相对运动的物体之间的摩擦损耗，人们往往通过使用润滑油来实现这一目的。正如发动机在运转时，如果一些摩擦部位得不到适当的润滑，就会产生干摩擦。实践证明，干摩擦在短时间内产生的热量足以使金属熔化，造成机件的损坏甚至卡死，许多漏水或漏油的汽车出现拉缸、抱轴等故障，主要原因就在于此。因此必须对发动机中的摩擦部位给予良好的润滑。
润滑油往往成液体或者半固体状，润滑油的构成一般为基础油加添加剂。润滑油主要起到减少摩擦、辅助冷却、防锈、清洁、密封和缓冲的作用。润滑油的基础油决定着润滑油的基本性质，其他改进的性能则主要通过加入添加剂得以实现。
粘度是反映润滑油流动性的重要质量指标。不同的使用条件具有不同的粘度要求。重负荷和低速度的机械要选用高粘度润滑油。粘度指数则指油品粘度随温度变化的程度，粘度指数的高低是润滑油性能的重要指标。粘度指数越高，表示油品粘度受温度的影响变化越小，其粘温性能越好；当粘度指数越低时，表示油品粘度受温度的影响变化较大，其粘温性能越差。
发明内容
针对上述缺陷，本发明的目的是提供一种高粘度指数润滑油的制备方法，在原有基础油中通过添加亚磷酸酯二正丙脂、乙氧酰胺苯甲酯等物质，使得制备得到的润滑油的粘度指数高，使用时润滑效果好。

（3）向步骤（2）中加入滑石粉3-7份，并将聚丙烯酰胺4-9份和聚乙烯吡咯烷酮3-5份的混合液滴加入步骤（2）中，边滴加边升高温度直至140-150℃，继续搅拌反应2-3h，待反应冷却后即可得到所述高粘度指数润滑油。
