Abstract

The invention belongs to the technical field of lubricating oil. The invention relates to bio-based lubricant base oil, which is prepared by taking hexagonal boron nitride, 3-(2-bromophenyl)propionic acid, dimethylchlorosilane and vegetable oil as raw materials through multiple reactions such as hydrolysis, esterification, substitution, hydrosilylation and the like. The problems that existing bio-based lubricating oil is poor in oxidation resistance, lubrication and abrasion resistance are effectively solved, meanwhile, the bio-based lubricating oil has excellent high and low temperature resistance, and synthetic raw materials are wide and environmentally friendly. It can be foreseen that the product has huge market potential.

Description

technical field [0001] The invention relates to a bio-based lubricant base oil. The invention belongs to the technical field of lubricating oil. Background technique [0002] Mineral oil-based lubricants have poor biodegradability and some are even ecotoxic. With the continuous strengthening of human environmental protection awareness and environmental protection legislation, the environmental pollution caused by mineral oil-based lubricating oil has attracted more and more attention, and the voice of environmental protection of lubricating oil has become increasingly loud. [0003] Vegetable oil is non-toxic and has good biodegradability, and can become the mainstream of environmentally friendly lubricants. Many developed countries have formulated strict laws to control the use and discharge of lubricating oils. For example, the German "Blue Angel" organization stipulates that environmentally friendly lubricants must be free of carcinogens, mutagenic substances, chlorine,...
