Abstract

The invention discloses a kind of thermostable lubricant basic oil, which comprises the following substances in parts by weight: 10 to 30 parts of n-hexanol, 15 to 35 parts of plant oil, 10 to 20 parts of poly(alpha-alkene) synthetic oil, 1 to 7 parts of potassium sodium tartrate, 0.5 to 1 part of 2,6-ditertbutyl p-cresol, 1.5 to 4 parts of polyvinylpyrrolidone, 0.1 to 0.35 part of amino-alcohol complex titanate, 1 to 3 parts of polymethacrylate, 0.1 to 0.4 part of hydrophobic silica, 5 to 17 parts of n-pentanol, and 10 to 28 parts of n-octanol. The thermostable lubricant basic oil has the advantages that: the source of the raw materials and reagents is abundant, environmental pollution is small; the method can solve the shortage of petroleum resource at present, and meets the environment protection requirements at the same time; the prepared biological lubricant basic oil has an excellent viscosity-temperature characteristic and thermostability, and effectively solves the problem of bad viscosity-temperature characteristic and thermostability when the plant oil is solely used as the lubricant.

Description

technical field [0001] The invention relates to a thermally stable lubricating base oil. Background technique [0002] The development of high technology and the strengthening of environmental protection regulations put forward higher requirements on the performance and environmental compatibility of lubricants. Traditional petroleum-based lubricants are not only facing the huge threat of resource scarcity, but also difficult to meet environmental compatibility requirements. Therefore, replacing mineral oil with resource-rich natural vegetable oils and developing high-performance bio-lubricating oil base oils are crucial to high-tech innovation and sustainable development. Development strategies play an extremely important role. Vegetable oil is a triglyceride formed by the combination of glycerin and fatty acid. Its structure contains a large number of unsaturated double bonds, which makes vegetable oil have good viscosity-temperature characteristics, and thus has outstand...
