特种复合锂基润滑脂及其制备方法
摘要：
本发明公开了一种特种复合锂基润滑脂及其制备方法，属于石油油脂技术领域。本发明的技术方案要点为：特种复合锂基润滑脂，是由以下重量份的原料制备而成的：十二羟基硬脂酸6.7%～10.7%；氢氧化锂0.5%～5.5%；氢氧化钙0.05%～0.5%；硼酸0.1%～0.5%；酯类物质0.5%～3.5%；余量为基础油。本发明还具体公开了该特种复合锂基润滑脂的制备方法。本发明制得的特种复合锂基润滑脂在复合锂润滑脂中成本较低，皂纤维结构复杂，具有较高的抗极压性能，同时抗氧化性能和耐高温性能均较好。
摘要（英）：

The invention discloses a special compound lithium-base lubricant and a preparing method thereof, and belongs to the technical field of petroleum grease. According to the technical scheme, the specialcompound lithium-base lubricant is characterized by being prepared from, by weight, 6.7-10.7% of 12-hydroxystearic acid, 0.5-5.5% of lithium hydrate, 0.05-0.5% of calcium hydroxide, 0.1-0.5% of boricacid, 0.5-3.5% of ester and the balance base oil. The invention further specifically discloses the preparing method of the special compound lithium-base lubricant. The prepared special compound lithium-base lubricant is low in cost, complex in soap fiber structure and high in extreme pressure resistance in compound lithium lubricants, and meanwhile oxidization resistance and high temperature resistance are good.
