Abstract

The invention discloses a high pressure hydrogenation naphthenic lubricating oil light stabilizer composition. The composition comprises, by mass, 80-90% of an ultraviolet light absorbent and a hindered amine light stabilizer 3,5-bis(1,1-dimethylethyl)-4-octadecyl hydroxybenzene phenylpropionate, and 10-20% of a tri[2,4-di-t-butylphenyl]phenyl phosphite chelating agent. The light stability of high pressure hydrogenation naphthenic lubricating oil can be obviously improved by adding 0.5-1% of the high pressure hydrogenation naphthenic lubricating oil light stabilizer composition to base oil ofa high pressure hydrogenation naphthenic lubricating oil composition.

Description

technical field [0001] The invention relates to a high-pressure hydrogenation naphthenic lubricating oil light stabilizer composition and its application in high-pressure hydrogenation naphthenic lubricating base oil. Background technique [0002] High-pressure hydrotreated naphthenic base oils have incomparable advantages over traditional base oils, such as high saturated hydrocarbon content, high viscosity index, low volatility, low sulfur and nitrogen content, light color, etc. The most obvious disadvantage of hydronaphthenic lube base oils is their poor light stability. Moreover, the poor light stability of high-pressure hydrogenated base oils is a common problem at home and abroad. It has been generally recognized that the main reason for the poor light stability of high-pressure hydrogenated naphthenic lubricating oil base oils is polycyclic aromatic hydrocarbons. For the problem of poor light stability of high-pressure hydrotreated naphthenic lubricating oil base oil...
