技术领域
本发明涉及润滑油脂制备技术领域，尤其是涉及一种精密仪器用抗磨耐热老化的润滑油及其制备方法。
背景技术
随着科技和社会的不断发展，各种各样的精密仪器得到了广泛的关注和发展，同时人们对各种精密金属零部件装配得到各种产品的使用环境、耐用强度、抗压强度等方面提出了更高的要求。精密仪器在运行过程中许多零部件之间需要使用润滑油脂润滑，以降低零部件之间的运行摩擦/磨损和/或接触不良，或者降低暴露在空气环境下/与空气接触的金属电镀层的氧化。受精密仪器本身的运行特性的影响，其内部核心控制部件在运行过程中容易产生较多的热量，现有的用于精密仪器的润滑油容易在受温状态下吸热软化、流失、挥发，或者产生热老化现象，严重降低润滑性能；而且许多精密仪器需要在短时/长时间低温环境下运行，例如冬季北方户外环境，要求使用的润滑油脂应该具有良好的耐低温性；同时，使用于精密仪器的润滑油脂应该具有良好的抗氧化性/抗热氧化性、防水性以及防腐性。
发明内容

进一步地，所述的复合基础油为氢化蓖麻油、聚α烯烃和石蜡油，其质量份比为2~4:1~3:1。
进一步地，所述的减摩润滑添加剂为苯三唑脂肪酸铵盐与甘油单油酸酯和/或甘油二油酸酯，其中苯三唑脂肪酸铵盐占质量比为20~40%。
进一步地，所述的改性添加剂为气相二氧化钛和氮化硅微粉，其质量份比为2~4:1。
所述的一种精密仪器用抗磨耐热老化的润滑油的制备方法，其包括以下步骤：将改性添加剂和二乙烯基苯偶联剂混合后，加入一半体积的复合基础油，于60~80℃下超声震动分散1~2h，然后置于均质机中于30~50MPa下高压均质一次；在得到的混合物中加入剩余其他原料，充分搅拌均匀，并在40~60MPa下高压均质一次，获得本发明的润滑油。
与现有技术相比，本发明具备的有益效果为：本发明采用高质量、高性能化的复合基础油与其他改性原料复合，经简单、有效的制备方法制得了润滑性好、防腐防锈抗磨、耐高低温稳定性良好、耐热老化性优良、可持续性好的润滑油；本发明得到的润滑油为粘稠细润液体，加工方法简单，使用方便，适用于高精密度的精密仪器。
