Abstract

The invention discloses a lube base oil and a preparation method thereof. The lube base oil comprises the following components in percentage by weight: 20-27% of rapeseed oil, 13-20% of olive oil, 21-33% of benzene tricarboxylate, 15-35% of tetraoctyl pyromellitate and 5-7% of polyglycol ether. Compared with the prior art, the lube base oil disclosed by the invention has lower condensation point and higher viscosity index, and is suitable for producing high-grade lube products. Meanwhile, the lube base oil has the advantages of favorable biodegradability, lower ecological toxicity and small environmental hazard.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a lubricating oil base oil and a preparation method thereof. Background technique [0002] Lubricating oil is one of the four major petroleum products. It is an important commodity related to the national economy and the people's livelihood. It is also an important symbol for various refining and chemical enterprises to display their own image, technical level and overall strength. After the lubricating oil market was liberalized in 1992, a large number of foreign lubricating oils poured in, and the competition with PetroChina, Sinopec, and many private, township, and collective enterprises in the domestic lubricating oil market became increasingly fierce. At present, the production situation of my country's lubricating oil is that the output exceeds the demand, but there is a big gap between the quality and the international level, and the level of base oil is not at t...
