Abstract

The invention belongs to the technical field of lubricating oil processing, and concretely relates to a preparation method of lubricating rust-preventive oil. The preparation method comprises the following steps: phospho-tungstic acid and benzothiazoles ionic liquid are grafted to prepare an immobilized ionic liquid catalyst which is used for catalyzing a catalytic reaction of rosin borate, the lubrication anticorrosion performance of the cutting fluid is effectively increased, tallol is used as a raw material, liquid SO3 is taken as the catalyst, the material and monoethanolamine are subjected to a reaction to generate tall oil acid monoethanolamine, finally, rosin borate, tall oil acid monoethanolamine, butyl stearate, white oil, tung oil, sodium hexametaphosphate, phenoxy-1-propanol , fatty alcohol polyoxyethylene ether, sodium dodecyl benzene sulfonate, an anti-oxidant, and a bactericide are used as the raw materials to prepare the lubricating rust-preventive oil.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil processing, in particular to a preparation method of lubricating antirust oil. Background technique [0002] After metal workpieces are cut or processed, they will rust due to the influence of temperature, humidity, oxygen content and other corrosive gases in the environment, which greatly reduces the value of metal products. In order to prevent metal products from rusting, various protective measures can be adopted for metal products to separate the metal products from the surrounding environment, thereby protecting the metal products from corrosion. Reasonable selection of anti-rust oil can have an ideal anti-rust effect on metal products. [0003] Lubricating and antirust oil can not only prevent rust on metal products, prevent air and moisture from contacting them to prevent metal products from rusting, but also have a lubricating effect on metal products, reduce wear and tear of meta...
