Abstract

The invention relates to a multi-effect lubricating oil additive, which is prepared from the following raw materials by weight: 6-10 parts of triethanolamine, 5-9 parts of ditert-butyl paracresol, 5-7 parts of sodium dodecyl benzene sulfonate, 3-6 parts of polyvinyl alcohol, 4-8 parts of nanometer silica, 3-6 parts of succinate, 1-5 parts of oleic acid, 4-10 parts of methyl acrylate, 5-10 parts of polyisobutylene succinimide, 3-6 parts of isopropanol, 1-4 parts of ethylene, 6-8 parts of zinc butyl octyl dithiophosphate, and 3-7 parts of molybdenum dibutyl dithiocarbamate. The multi-effect lubricating oil additive has the following beneficial effects that: the extreme pressure resistance of the lubricating oil can be improved, the good cleaning property and the good chemical stability are provided, and the service life of the lubricating oil can be prolonged.

Description

technical field [0001] The invention relates to a multi-effect 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 ...
