Abstract

The invention relates to an oil film bearing lubricating oil with high water separation performance. The invention is characterized in that the oil film bearing lubricating oil comprises the following materials of: bi-polyisobutene succimide, phytic acid, 6-tert-butyl-3-methyl phenol, triphenyl thiophosphate, dialkyl pentasulfide, triazole octadecylamine salt, di(2, 4-ditert-butyl phenyl) pentaerythritol biphosphite ester, butyl isooctylphosphate laurylamine salt, dodecene hydrocarbon butane diacid, oxozone trimethylene derivates of amine, petroleum acid polyether ester, polyacrylic ester, oil-soluble polyether macromolecular compound, bisphenyl propyl dimethyl siloxane and base oil. The product has excellent water separation performance and good extreme-pressure abrasion resistance, and can meet the special requirements of working conditions of humidity and wateriness.

Description

technical field [0001] The invention relates to an oil-film bearing lubricating oil with high water-separation performance, which is suitable for lubricating oil-film bearings at support rolls of rolling mills such as high-speed bars, high-speed plates and high-speed wires in the metallurgical industry, and belongs to the field of chemical industry. Background technique [0002] With the continuous development of industry and cities, the demand for steel in the automobile, construction, aviation and other industries has increased sharply, prompting the development of various rolling mills to high speed. The essential difference between the high-speed rolling mill and the traditional rolling mill is that it eliminates the twisting process of the traditional rolling mill from ellipse to round, and greatly increases the rolling speed, the highest rolling speed can reach 130m / s. The finishing unit of the high-speed rolling mill is composed of main components such as speed-up gea...
