Abstract

The invention discloses a method for preparing organic silicon modified plant oil. The method comprises the following steps of: by taking colza oil as a raw material, preparing a colza oil alcohol orderly through methanol ester exchange, peracetic acid epoxidation and acetic acid ring opening; and then reacting organic silicon with the hydroxyl in the colza oil alcohol, thereby obtaining the organic silicon modified plant oil. The organic silicon modified plant oil produced by the method has good lubrication effect; and in addition, the oxidation stability of the organic silicon modified plant oil is also greatly improved.

Description

1. Technical field

[0001] The invention relates to a method for preparing modified lubricating oil, in particular to a method for preparing organosilicon-modified vegetable oil. 2. Background technology

[0002] The increase in world oil consumption and the decrease in reserves have prompted people to look for energy alternatives. In recent years, since various lubricant products will enter the natural environment through steam, leakage or spillage, the pollution of lubricants and environmental health issues have gradually attracted attention, and the development of environmentally friendly lubricants has become a global consensus. As the base oil of industrial lubricants, vegetable oil exhibits good lubricating performance, good corrosion resistance, good viscosity-temperature performance and low evaporation loss. In addition, compared to mineral oil, vegetable oil has better biodegradability and is a green and environmentally friendly lubricant. However, vegetable oil it...
