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 lubricant composition for an explosion-proof motor, and is characterized in that the composition contains: on a weight basis, 20-60 parts of a lower polyol, 0.001-2 parts of glycerophosphate, 0.001-3 parts of boride, 0.02-0.1 parts of a stabilizer, and 25-80 parts of water, wherein the glycerophosphate is at least one of ammonium glycerophosphate, sodium glycerophosphate, potassium glycerophosphate, calcium glycerophosphate and magnesium glycerophosphate; the boride is at least one of ammonium pentaborate, borax, boric acid and stannous fluoborate; and the lower polyol is at least one of ethylene glycol, propylene glycol, glycerin, butanediol and pentanediol.

Description

technical field [0001] The invention relates to a lubricant composition 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...
