Abstract

The invention relates to a lubricant. The lubricant is composed of the following components in parts by weight: 79-86 parts of polyamide-imide resin, 17-21 parts of butyl acetate, 16-19 parts of an abrasion-resistant additive, 7-9 parts of boric acid, 11-15 parts of a zirconium-manganese powder mixture and 30-40 parts of a mixed solvent, wherein the mixed solvent is a liquid mixture of N-methyl pyrrolidone, dimethyl formamide, methyl isobuthyl ketone, glycol and ethanol having a mass ratio of 1-2: 2-3: 4-6: 1-2: 7-9. The lubricant disclosed by the invention not only has very high abrasion performance at a room-temperature atmosphere, but also has goodish effects at a high temperature.

Description

technical field [0001] The present invention relates to a lubricant. Background technique [0002] Lubricants are usually composed of resin binders, solid lubricants, wear-resistant additives, and pigments. Lubricants are different from oils and greases that are commonly used. They cannot be replenished. Under dry friction conditions, their lubricating effect mainly depends on a thin film with a thickness of several microns to tens of microns adhered to the substrate. Once the film is worn through, the lubrication is lost. Therefore, improving the service life of the dry film is the main research direction of developing dry film lubricants. [0003] The existing lubricants are characterized by high load bearing capacity, low coefficient of friction, and can be used under high load conditions. Molybdenum disulfide type lubrication has good application characteristics in vacuum environment. However, when used under medium and light load conditions, its service life is not ...
