Problems solved by technology

There is also a lubricant in the prior art, which uses liquid (such as alcohol) to make boron nitride into suspended lubricant particles, and then sprays or brushes it on the friction surface of the mold or mechanical parts, but this lubricant is loosely located in the mold Or on the surface of mechanical parts, and is very easy to be wiped off

Abstract

The invention relates to a quick drying type high-temperature dry-film lubricant. The lubricant is prepared from the following components in percentage by weight: 8%-12% of nano-boron nitride powder, 0.8%-1.2% of cellulose nitrate, 0.2%-0.3% of polyurethane, 75%-85% of acetone and 5%-12% of ethyl acetate. The dry-film lubricant is mainly used for lubrication protection and service life prolonging of a mold; the dry-film lubricant can be air-dried after covering the mold for 1-2 minutes; by the aid of the nano-boron nitride powder, the dry-film lubricant can have good oxidation resistance and high-temperature resistance and quite high economic use value, and the high-temperature resistance reaches 1000 DEG C.

Description

technical field [0001] The invention relates to a dry film lubricant, in particular to a quick-drying high temperature dry film lubricant. Background technique [0002] Lubricants are widely used on the friction surfaces of molds and mechanical parts to reduce friction and wear of materials. Compared with conventional grease lubrication, dry film lubricants can be effectively used under environmental conditions such as high temperature, high load, and high vacuum. [0003] In the prior art, the solid lubricant (molybdenum disulfide, graphite powder, etc.) is dispersed in an organic or inorganic bond, coated on the friction surface with the mold and mechanical parts, and dried to obtain a dry film lubricant coating , the film lubricant can reduce the friction and wear of materials, but its working temperature usually does not exceed 450°C. There is also a lubricant in the prior art, which uses liquid (such as alcohol) to make boron nitride into suspended lubricant particles...
