Problems solved by technology

[0002] The light stability of lubricating oil base oil has always been a problem that affects the appearance of base oil. Specifically, when the base oil is exposed to light, its appearance color will become darker. The color is getting darker and darker, resulting in darker color of the product blended with base oil, which affects the user's perception of the appearance of the lubricant, and thus doubts the quality of the product

Abstract

The invention relates to a lubricating oil base oil light stabilizer composition and its preparation method and application, comprising the following components in parts by weight: 10-30 parts of antioxidant, 20-50 parts of detergent, 20-50 parts of dispersant, 10-20 parts of ultraviolet absorber. The invention forms a new mixture by optimizing the combination of several lubricating oil additives, and the new composition can greatly improve the light stability of the base oil.

Description

technical field [0001] The invention relates to a lubricating oil base oil light stabilizer composition, a preparation method and application thereof. Background technique [0002] The light stability of lubricating oil base oil has always been a problem that affects the appearance of base oil. Specifically, when the base oil is exposed to light, its appearance color will become darker. The color is getting darker, which leads to the darker color of the products blended with base oil, which affects the lubricating oil users' perception of the appearance of the lubricating oil, and thus creates doubts about the product quality. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a lubricating oil base oil light stabilizer composition, by optimizing the combination of several lubricating oil additives and adding them to the base oil in a certain proportion, the light stabilizer composition of the base oi...
