Abstract

The invention relates to modified composite titanium-based grease of micron-nano particles and a preparation method thereof. In order to solve the problem of low antiwear and friction reduction properties of existing composite titanium-based grease, the preparation method comprises the following steps of firstly, mixing fatty acid and a part of base oil and then adding tetraisopropyl titanate, aromatic acid and distilled water; pre-heating the residual base oil and then adding the residual base oil to a reaction system, adding diphenylamine and a micron-nano additive, and grinding after the reaction is finished to obtain the modified composite titanium-based grease of the micron-nano particles. Compared with the composite titanium-based grease, the friction coefficient is reduced by 16.9-29.3%; the diameter of a wear spot is reduced by 21.4-32.7%; the antiwear and friction reduction properties are improved; the prepared composite titanium-based grease has good self-repairing performance by adding hydroxyl magnesium silicate powder with the self-repairing performance; and the modified composite titanium-based grease can be applied to various mechanized equipments and devices.

Description

technical field [0001] The invention relates to a lubricating grease modified by micronano particles and a preparation method thereof. Background technique [0002] Friction and wear is a ubiquitous phenomenon in nature. According to statistics, friction consumes 1 / 3 to 1 / 2 of the world's energy, and wear is one of the main forms of failure and destruction of equipment and materials. About 80% of parts are damaged due to Wear and tear, and the use of lubricating grease can effectively reduce friction and wear. Although the output of lubricating grease only accounts for about 5% of lubricating oil output, it is widely used in rolling, rotating, sliding and other parts that cannot be lubricated by lubricating oil, such as bearings and gears, and occupies a very important position in the national economy. As heavy load, high speed, high temperature and other equipment are more and more widely used in modern industry, various departments of industrial production have put forwar...
