Composite calcium sulphonate lubricating grease

Abstract

A composite lubricating oil with high-temp performance, shearing stability, water-proofing nature, extreme-pressure performance and viscosity is prepared through proportionally mixing high-viscosity mineral oil with calcium sulfonate, glacial acetic acid, boric acid and calcium hydroxide, convension and saponifying reaction, adding fatty acid, high-temp (180 deg.C) reaction, cooling to 110 deg.C, adding antioxidizing agent, extreme-pressure agent and oily agent, homogenizing and filter.

Description

technical field

[0001] The invention relates to a kind of lubricating grease which takes high-viscosity mineral oil as base oil and uses synthetic calcium sulfonate with high alkali value, fatty acid, boric acid, glacial acetic acid and calcium hydroxide as thickeners, and the compound calcium sulfonate lubricating grease. Background technique

[0002] With the rapid development of the metallurgical industry, the working conditions of equipment in rolling mills are becoming more and more harsh. Most of the equipment bearings in medium-sized factories, bar factories, medium plate factories, and hot-rolled strip mills operate under high temperature, high speed, heavy load, water, Running in a dusty environment puts forward higher requirements on the performance of the grease used in the rolling equipment bearings.

[0003] At present, the lubricating grease used for bearings of steel rolling equipment is mainly based on extreme pressure lithium base grease or extreme pressure ...
