Lubricating oil additive

Abstract

The invention relates to a lubricating oil additive, which is prepared from the following raw materials by weight: 8-14 parts of sulfur phosphorus primary-secondary alkyl zinc salt, 3-10 parts of sulfurized isobutylene, 4-8 parts of glycerol acrylate, 3-7 parts of isooctyl phosphate, 2-7 parts of methyl silicone oil, 3-5 parts of calcium stearate, 6-8 parts of a butene adhesion agent, 3-9 parts of a dibenzyl disulfide, 1-5 parts of dibutyl phosphite, 4-7 parts of dodecylbenzene, 1-5 parts of diethanolamine, and 6-8 parts of carbon tetrachloride. The lubricating oil additive of the present invention has following beneficial effects of improvement of the lubricating effect and the washing effect of the lubricating oil, anti-oxidation and wide use.

Description

technical field [0001] The invention relates to a lubricating oil additive. Background technique [0002] Lubricating oil is a liquid lubricant used on various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the role of reducing friction, cooling, sealing, buffering, rust prevention, cleaning and neutralization. However, with the enlargement and automation of equipment, the requirements for machining accuracy of workpieces are getting higher and higher, so the performance requirements for lubricating oil are also getting higher and higher. Lubricating oil additives can improve the performance of lubricating oil, so that the lubricating oil has better oxidation resistance, anti-wear properties, friction improvement properties, extreme pressure properties, detergency, dispersibility, foam suppression and so on. However, the existing additives generally have insufficient performance and cannot meet the requirements of use. Con...
