Thereafter, lithium hydroxide and calcium hydroxide are added to the mixture, and the mixture is then neutralized by heating it to a temperature of from about 360 to about 450 degrees Fahrenheit. The saponified mixture is then comminuted so that at least about 90 weight percent of the particles in it are smaller than 1 micron. To this comminuted mixture is then added another portion of the specified paraffinic bright stock oil.

A kind of heavy duty high/low temperature preparation of greases method

本发明公开了一种重载高低温润滑脂的制备方法，具体步骤为：将60‑65重量份的基础油和5‑10重量份的脂肪酸于80℃混合1小时，升温至80‑100℃加入3‑5重量份的烷氧基钛并皂化1小时，再加入1‑3重量份的水并升温至100‑210℃稠化4‑6小时，待水完全蒸发后加入10‑15重量份的基础油和0.5‑1.5重量份的抗氧剂，搅拌降温至90℃以下，进行冷却、研磨得到重载高低温润滑脂。本发明有效解决了当前重载设备润滑脂寿命有限的技术难题，并且该润滑脂和其它润滑脂的相容性较好，是一种多功能多效润滑脂，具有生物降解性能，对环境保护有很大的作用。
