specific Embodiment approach

[0024] As a specific embodiment, it includes the following components by mass percentage, nitrogen-containing borate 5%, polyol ester 70%, rare earth solution 3%, graphene 1%, silane coupling agent 1%, anti-settling 1% agent, 1% dispersant and 18% base oil.

[0025] Nitrogen-containing borates include fatty acid diethanolamide or triethanolamine borates. Polyol esters include trimethylolpropane or pentaerythritol esters of C5-C9 fatty acids. Silane coupling agents include titanate coupling agents. The dispersant is a nonionic dispersant. The base oil is mineral oil.

[0026] Rare earth and graphene without sulfur and phosphorus can effectively improve the anti-wear and anti-friction performance of automobile engines, increase engine power, reduce engine noise, improve engine internal cleaning ability and prolong engine life, save gasoline and diesel energy, and reduce carbon monoxide and carbon monoxide in automobiles. The emission of toxic gases such as sulfur dioxide pro...

Abstract

The invention discloses a lubricant additive and a preparation method thereof. The lubricant additive is prepared from, by mass, 5%-8% of nitrogenous boric acid ester, 65%-75% of polyol ester, 3%-5% of rare earth solution, 1%-2% of graphene, 1%-2% of a silane coupling agent, 1%-2% of an anti-settling agent, 1%-2% of a dispersing agent and 13%-25% of base oil. The lubricant additive and the preparation method thereof have advantages that temperature resistance, lubricity and abrasion resistance of lubricants are improved, the service life of an internal combustion engine is effectively prolonged, and poisonous gas emission is reduced.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil additive and a preparation method thereof. Background technique [0002] Zinc dialkyldithiophosphate (English abbreviation ZDDP) has a good anti-wear and anti-oxidation mechanism, low cost and high performance. In the automotive internal combustion engine oil industry, this basic additive is usually added to engine oil or lubricating oil. However, because ZDDP contains sulfur and phosphorus, fuel or lubricating oil contains sulfur, phosphorus and other toxic and harmful substances, which is one of the reasons for the aggravation of air pollution, and sulfur, phosphorus and other toxic and harmful substances will shorten the service life of the catalyst of the exhaust gas purification device. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Contents of the invention [0003] The purpose of the pre...
