Problems solved by technology

Most of the existing dry film lubricant products are based on molybdenum disulfide, and often contain heavy metal lead, and these lubricants have poor wear resistance under high load-carrying capacity and high-speed operation. The wear resistance of the product applied to the swash plate parts of the automotive air-conditioning compressor is not satisfactory

Abstract

The invention relates to a tungsten disulfide based high-temperature dry-film lubricant which comprises the following components according to the weight percent: 20-70 of caking agent, 5-30 of tungsten disulfide, 5-30 of polyfluortetraethylene, 0.2-20 of wear resistant filling material, 10-40 of component solvent and the balance of addition agent. Compared with the prior art, the invention has the characteristics of high loading capacity, better wear resistance under the condition of high rotating speed, wide processing temperature range and the like.

Description

technical field [0001] The invention relates to a lubricant, in particular to a tungsten disulfide-based high temperature resistant dry film lubricant. Background technique [0002] In order to reduce the wear and power consumption caused by the mechanical movement of equipment and components, people usually reduce friction and reduce wear by coating or adding lubricating grease. Most of the existing dry film lubricant products are based on molybdenum disulfide, and often contain heavy metal lead, and these lubricants have poor wear resistance under high load-carrying capacity and high-speed operation. The wear resistance of this product applied to the swash plate parts of the automobile air-conditioning compressor is not satisfactory. Contents of the invention [0003] The purpose of the present invention is to provide a tungsten disulfide-based high-temperature-resistant dry film lubricant with high load-bearing capacity, better wear resistance under high-speed conditio...
