Problems solved by technology

In recent years, there have been substitutes for chlorinated paraffin, but the price of the substitute is high, the extreme pressure activity is not too high, and chlorinated paraffin is still inseparable from metals that are difficult to process.
Chlorinated paraffins produced in my country are poorer in thermal stability, hydrolytic stability and corrosion inhibition than similar foreign products

Abstract

The invention belongs to the field of lubricating oil and in particular relates to a lubricating oil antifriction additive and a preparation method thereof, wherein the lubricating oil antifriction additive comprises an antifriction agent, a clean dispersing agent and an antioxidant preservative. The preparation method of the lubricating oil antifriction additive comprises the following steps: evenly mixing diglycolamide oleate borate, dibutyl phosphite and cyclohexyloxy cupric borate in advance at normal temperature and normal pressure to prepare the antifriction agent for later use; evenly mixing amine polybutylene, polyisobutylene carbamate and diaminopyridin to prepare the clean dispersing agent for later use; and adding the clean dispersing agent into the antifriction agent, and then adding the preservative boride butadiene imide, and quickly stirring to prepare the lubricating oil antifriction additive. The preparation method is simple and easy to operate; and the additive is good in antifriction effect, long in service life, small in adding amount in the lubricating oil and economical.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a preparation method of an antiwear additive for lubricating oil. [0002] Background technique [0003] Lubricating oil is a liquid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. It is mainly used to reduce the friction between the surfaces of moving parts, and at the same time, it has the functions of cooling, sealing, anti-corrosion, anti-rust, insulation, power transmission, and cleaning impurities for machinery and equipment. It mainly uses lubricating oil fraction and residual oil fraction from crude oil distillation unit as raw material. The most important properties of lubricating oil are viscosity, oxidation stability and lubricity, which are closely related to the compositio...
