Abstract

The invention relates to a lubricating grease pressure-resistant additive which is basically characterized by consisting of the following components in percentage by weight: 29-33% of all polyolefin fluoride, 20-22% of dialkyl two glucosinolate and carbamate antimony, 3-5% of phenothiazine, 3-5% of fatty amine, 3-5% of di-salicyl propane diamine, 5-7% of dialkyl group dithiocarbamicacid metal salt, 3-5% of polyisobutene, 3-5% of alkyl succinimide and the balance of base oil. The preparation of the lubricating grease pressure-resistant additive is simple, convenient, feasible, economical and practical, and the lubricating grease pressure-resistant additive can maintain good long-time grease consistence, ensures stabile pressure-resistant performance of gears, bearings and mechanical parts under heavy load and impact load, improves comprehensive maintenance of various devices using the lubricating grease, comprehensively improves the performances of the lubricating grease and prolongs the service life of the lubricating grease.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation scheme and a preparation method of a lubricating grease anti-extreme pressure additive. (two) background technology: [0002] Because the semi-solid state of the grease makes it easier to seal the grease into the bearing, the grease also acts as a seal against contamination in wet and dusty environments. Therefore, the use of lubricating grease is in great demand. With the progress of society and the development of human science, all kinds of mechanical equipment are constantly developing, so it is required to improve the working performance of various lubricants. Grease should improve various performances because of its working characteristics. In applications where shock loading occurs, such as in large excavator bearings and some conveyor belt bearings, the rapid loading of the load can cause galling of the metal before the dissolved extreme pressure additive...
