Abstract

The invention relates to a wear-resistant additive for lubricating oil. The additive comprises the following components in parts by mass: 1-5 parts of nano calcium carbonate, 2-4 parts of nano boron nitride, 3-6 parts of nano molybdenum disulfide, 2-8 parts of expanded graphite, 3-6 parts of nano cerium borate, 1-5 parts of nano zirconium oxide, 2-8 parts of nano aluminum oxide, 1-6 parts of nanotitanium dioxide, 1-8 parts of nano silicon dioxide, 3-5 parts of N,N'-di-sec-butyl-p-phenylenediamine, 4-6 parts of di-tert-butyl-p-cresol, 2-5 parts of polyvinyl alcohol, 2-8 parts of methyl acrylate, 1-5 parts of pentaerythritol, and 2-8 parts of nano zinc oxide. The ceramic-like layer formed by the additive for the lubricating oil provided by the invention has ultra-high hardness and super wear resistance, and the overhaul period of an engine is prolonged; and the additive has the advantages of having good lubricating performance, saving oil, reducing jitter, reducing engine noise, promoting power, alleviating or thoroughly treating the phenomenon of burning engine oil, and reducing harmful gases in tail gases.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to a wear-resistant lubricating oil additive and a preparation method thereof. Background technique [0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to the lubricating oil. The traditional lubricating oil additives are sulfur, phosphorus or chlorine type anti-wear agents, which are corrosive to friction pair materials. Selectivity, especially lubricating oil additives containing elements such as sulfur, phosphorus or chlorine, will emit exhaust gas and pollutants during use, thus causing pollution to the environment. Contents of the invention [0003] The invention provides a wear-resistant lubricating oil additive and a preparation method thereof to solve the problems of corrosion and selectivity in traditional lubricating oil additives, and is convenient for industrial popularizatio...
