Problems solved by technology

With the rapid development of modern industry and the increasingly prominent environmental problems, the requirements for lubricant performance, operational reliability and service life, high temperature stability, low or non-toxicity, etc. are getting higher and higher. Traditional minerals are made of Base oils have been difficult to meet these stringent requirements
Due to the small molecular weight of synthetic ester compounds, the high temperature resistance is average, and it is easy to degrade and generate carbon deposits under high temperature.

Abstract

The invention discloses a high-temperature-resistant polyester lubricating oil base oil and a preparation method thereof, belonging to the field of fine chemicals. The base oil is composed of 1,3,5-cyclohexanetrimethanol, diethyl fluoromalonate, 12-benzoyl stearic acid, 2,2-difluoropropionic acid, 3-fluoro-4- Hydroxybenzoic acid, perfluoroheptanoic acid, and tris(trimethylsilyl) phosphate are the main raw materials. Using fluorine-containing carboxylic acid and 1,3,5-cyclohexanetrimethanol with excellent heat resistance as the main raw materials, introducing 12-benzoyl stearic acid and 3-fluoro-4-hydroxybenzoic acid to adjust the base oil The viscosity index, tris(trimethylsilyl) phosphate is used as a high temperature resistant antioxidant. The use of fluorinated compounds in the raw materials ensures the high temperature resistance and carbon deposition resistance of the product. The preparation method has easy-to-obtain raw materials and simple operation. The prepared lubricating oil base oil has excellent high temperature resistance, moderate viscosity index, good lubricating performance and wear resistance. It can be applied to the lubrication of most vehicle engines, especially suitable for high temperature environments.

Description

Technical field [0001] The present invention relates to a lubricating oil base oil and a preparation method thereof, specifically, a high temperature-resistant polyester lubricating oil base oil and a preparation method thereof, belonging to the field of fine chemical. Background technique [0002] Lubricants are indispensable chemicals in mechanical operation, and are widely used in various fields of national economy. With the further promotion of economic globalization, especially the rapid development of automotive industries, and strengthening environmental, energy-saving requirements, although the total demand for lubricants has not increased significantly, the demand for high-end lubricants has gradually increased. [0003] Lubricants are mainly composed of two parts: base oil and additives, where the base oil is the main component of lubricants, accounting for more than 85%, and plays an important role in the basis of lubricants. Therefore, the performance of lubricants ma...
