Novel low-temperature resistant lubricant formulation

Abstract

The invention provides a novel low-temperature resistant lubricant formulation. Raw materials in the formulation include, by weight, 5%-15% of base oil, 1%-5% of lubricant additive, 1%-10% of graphite, 5%-15% of bentonite, 3%-9% coupling agent, 2%-3% of nonylphenol polyoxyethylene ether, 1%-5% of hexachlorocyclopentadiene, 11%-19% of ethanedithiol, 5%-7% of propolis extract, and 3%-5% of seaweed extract. Novel low-temperature resistant lubricant prepared by the formulation has strong low temperature resistance.

Description

technical field [0001] The invention is a new formula of low temperature resistant lubricating oil. Background technique [0002] At low temperatures in existing lubricating oils, the crystals in the lubricating base oil crystallize out. Form a three-dimensional network structure and lose fluidity. In order to maintain the low-temperature fluidity of the oil, there are two ways. One is to deeply dewax the base oil to obtain lubricating oil with a low pour point, but it will damage the quality of the oil; Second, adding a small amount of pour point depressant to lubricating oil can significantly improve the shape and structure of wax crystals in the oil, thereby lowering the freezing point; generally, the alkyl side chains of pour point depressants use monomers with different carbon numbers Copolymerization, adjust the average side chain carbon number to adapt to different lubricating oil base oils, however, most of these pour point depressants use monoester or polyester wit...
