Abstract
本发明公开了一种含胆甾醇润滑油的制备方法。在润滑油中加入重量比为0.05%～4.0%的胆甾醇作为添加剂，加热至80℃～90℃搅拌均匀，然后冷却到常温使用。胆甾醇添加剂不仅可以减摩耐磨、提高摩擦副的抗胶合能力；而且在润滑油中均匀添加胆甾醇很方便，无污染。胆甾醇添加剂可以显著改善齿轮、蜗杆、滚动轴承、滑动轴承等机械零部件的减摩耐磨性能，并能显著提高摩擦副的抗胶合能力。
Description
技术领域
本发明涉及润滑油，特别是涉及一种含胆甾醇润滑油的制备方法。
背景技术
现有机械油的抗胶合能力较低，为了提高润滑油、润滑脂的耐磨减摩性能、提高抗胶合能力，以前人们采用添加纳米金刚石粉、纳米碳酸钙等来提高摩擦副的抗胶合能力。由于纳米粉末容易凝聚、分散困难，需通过对纳米粒子进行表面修饰才能达到较好的分散性。
发明内容
本发明的目的在于提供一种含胆甾醇润滑油的制备方法。
本发明采用的技术方案是：在润滑油中加入重量比为0.05％～4.0％的胆甾醇作为添加剂，加热至80℃～90℃搅拌均匀，然后冷却到常温使用。
所述的润滑油为机械油。
本发明具有的有益效果是：胆甾醇添加剂不仅可以减摩耐磨、提高摩擦副的抗胶合能力；而且在润滑油中均匀添加胆甾醇很方便，无污染。胆甾醇添加剂可以显著改善齿轮、蜗杆、滚动轴承、滑动轴承等机械零部件的减摩耐磨性能，并能显著提高摩擦副的抗胶合能力。

具体实施方式
本发明在润滑油中加入重量比为0.05％～4.0％的胆甾醇作为添加剂，加热至80℃～90℃搅拌均匀，然后冷却到常温使用。所述的润滑油为机械油。
胆甾醇的分子式如图1所示，胆甾醇的结构特点是C-3上有一个β-构型的羟基，C-5和C-6之间有一个双键，C-17上有一个含8个碳原子的烃基侧链。
在润滑油中添加0.05％～4.0％(重量)的胆甾醇，然后加热润滑油、并搅拌润滑油，胆甾醇在润滑油中就均匀分散。待润滑油冷却后，就可以使用。
图2、图3、图4、图5是本发明的典型案例实验结果，用MMW-1型立式万能摩擦磨损试验机的四球试验来评价润滑油的摩擦学机械性能。
图2是N15号机械油在26℃时的摩擦系数变化，在载荷400牛顿、转速1200转/分情况下，以摩擦力矩900牛顿·毫米判断胶合失效，以N15号机械油润滑的四球摩擦副11分钟后发生胶合失效。
图3是添加了4.0％(重量比)胆甾醇添加剂后的摩擦系数变化，载荷400牛顿、转速1200转/分情况下，以摩擦力矩900牛顿·毫米判断胶合失效，四球摩擦副22分钟后发生胶合失效。
图4是添加了1.92％(重量比)胆甾醇添加剂后的摩擦系数变化，四球摩擦副120分钟内没有发生胶合失效。
图5是添加了0.05％(重量比)胆甾醇添加剂后的摩擦系数变化，四球摩擦副120分钟内没有发生胶合失效。
试验案例表明，在N15号机械油中添加少量胆甾醇后，润滑油经加热、冷却后使用，以胆甾醇作为添加剂的润滑油显著提高摩擦副的抗胶合能力，摩擦力矩也下降，提高了摩擦副的减摩耐磨能力。
上述具体实施方式用来解释说明本发明，而不是对本发明进行限制，在本发明的精神和权利要求的保护范围内，对本发明作出的任何修改和改变，都落入本发明的保护范围。
