Problems solved by technology

For this purpose, lubricating oil compositions based on perfluoropolyether oils are used, but such base oils also have such a large surface area that they can coexist in contact with various metals or solid lubricants, so even perfluoropolyether Ether oils also cannot maintain stable high-temperature properties that depend on their structure

Abstract

The invention discloses a solid lubricant used for an explosion-proof motor. The lubricant is characterized by comprising, by volume, 1 to 5% of polyethylene resin, 30 to 50% of hydrocarbon waxes, 20 to 60% of melamine cyanurate, 5 to 20% of polyamide resin and 4 to 8% of modified polyethylene resin, wherein the modified polyethylene resin is graft modified polyethylene resin prepared from grafting monomer and polyethylene resin by grafting and polymerization, and the grafting monomer is one or a mixture of two or more selected from the group consisting of alpha,beta-unsaturated carboxylic acid, alpha,beta-unsaturated carboxylic acid anhydride and alpha,beta-unsaturated carboxylic acid derivatives.

Description

technical field [0001] The invention relates to a solid lubricant for an explosion-proof motor. Background technique [0002] Sintered oil-impregnated bearings are composed of porous bodies formed by compressing various solid powders. The solid powders are obtained by adding solid lubricants such as graphite, molybdenum disulfide, and carbon black to metal powders such as iron, copper, tin, and zinc. Sintered oil-impregnated bearings can be used without adding oil due to the self-lubricating effect of a small amount of lubricating oil impregnated in the initial stage. Therefore, a sufficient amount of lubricant can be kept in the bearing for a long period of time, and it can be used stably, which is very important for the life of the bearing. [0003] As automobile bearings, the use of sintered oil-impregnated bearings, which are cheaper than ball-roller bearings, is increasing, and the lubricants used in such sintered oil-impregnated bearings are inevitably placed in a pos...
