Green environmental-protection total synthesis high-temperature-resistant chain oil and preparation method thereof

Abstract

The present invention relates to the field of chemical industry, more particularly to a green environmental-protection total synthesis high-temperature-resistant chain oil and a preparation method thereof. The green environmental-protection total synthesis high-temperature-resistant chain oil comprises a 1-ethyl-3-hexylimidazolium diethylphosphonate ion liquid, sulfurized calcium alkyl phenolate, polyisobutylene succinimide, a benzotriazole octadecylammonium salt, an alkylated diphenylamine antioxidant, a pour point depressant, and an antifoaming agent. The preparation method comprises two steps such as synthesis of a 1-ethyl-3-hexylimidazolium diethylphosphonate ion liquid and mixing of raw materials. According to the present invention, the volatilization loss of the 1-ethyl-3-hexylimidazolium diethylphosphonate ion liquid adopted as the base is low, the coking is less, the formed coke can be dissolved in the new oil, the blended high temperature chain oil product quality achieves the international leading level, and after the product is produced, the high quality high temperature chain oil can be provided for the production of the domestic lubricating oil, and the road can be developed for the practical application of the ion liquid as the base oil in the lubricating oil.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a green and environment-friendly fully synthetic high-temperature-resistant chain oil and a preparation method thereof. Background technique [0002] Since the 19th century, chains have been used as transmission equipment in various fields of industry. With the development of modern industrial technology, the operating conditions of the chain are becoming more and more harsh, with the highest operating temperature reaching 260°C and the fastest speed reaching 400m / min. The corresponding high-temperature chain oil is required to have excellent high-temperature stability, less coking and the formed coke can be dissolved into the new oil, thereby prolonging the coke cleaning cycle, low volatilization loss, reducing oil consumption and avoiding oil dripping pollution; if the lubricating performance is excellent , which can ensure the smooth operation of the chain on the slide rail; ...

AI Technical Summary

Problems solved by technology

Although polyether chain oil decomposes at high temperature, it is not easy to form coking and hard residues, but the gas formed by decomposition or volatilization at high temperature permeates the factory building, affecting the physical and mental health of workers. At the same time, the residual oil on the chain cannot ensure sufficient lubrication of the chain, shortening the chain life

Therefore, it is not suitable to use polyether type high temperature chain oil in the working condition higher than 220°C
