Abstract

The invention discloses a heat-resistant lubricating oil which is composed of the following raw materials in parts by weight: 7-9 parts of bisphenol A, 4-5 parts of tributyl borate, 0.01-0.03 part ofa catalyst, 20-30 parts of wood creosote, 70-90 parts of base oil, 1-2 parts of trithiocyanuric acid, 0.5-1 part of diphenyl imidazoline, 3-5 part of diacetone alcohol, 1-2 parts of sucrose acetate isobutyrate, 0.8-1 part of calcium acetylacetonate and 0.6-1 part of zinc acetylacetonate. The heat-resistant lubricating oil not only has good heat-resistant stability, but also has good dispersity with the base oil, and can effectively improve the heat-resistant stability of the finished product oil.

Description

technical field [0001] The invention belongs to the oil field, and in particular relates to a heat-resistant lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in large quantities, but in some applications, products formulated with synthetic base oils and bio-oil base oils must be used, which has led to rapid development of these two base oils; however, due to the relatively single functionality of traditional lubricants , so it is particularly necessary to impr...
