Background

With the continuous improvement of the performance of modern mechanical equipment and the requirement of the modern environment-friendly era, the traditional lubricating oil additive containing high zinc, sulfur and phosphorus becomes the elimination trend, and the search for a substitute is urgent.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, provides a super anti-wear composite additive, belongs to the technical field of functional materials, and particularly relates to a lubricating oil super anti-wear composite additive with super adsorption, super anti-wear, dynamic restoration and metal surface hardening functions and a preparation method thereof.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention selects the alkyl arylamine group dithiophosphate oxysulfide (WDATP), the alkyl arylamine group dithiophosphate oxysulfide (MoDTP) and the dialkyl diarylbenzylamine group zinc phosphate with better extreme pressure abrasion resistance and oil solubility, and the synergistic action generated by alkyl, aryl and amino is assisted by auxiliary materials to show excellent oxidation resistance, corrosion resistance, antifriction and cleaning dispersion performance; polar atoms such as sulfur, phosphorus and the like in organic tungsten, molybdenum and zinc rapidly generate a series of complex chemical reactions under the catalysis in a high-pressure and high-temperature friction environment in which a friction pair breaks through an adsorption layer to form a reinforced covering layer of substances such as WS2, MoS2 and FeS, the covering layer can reconstruct a high-hardness metal surface on the basis of filling a friction wound surface, not only can be dynamically repaired, but also can improve the clearance of the friction pair to enable the clearance to tend to be reasonable, and the coating has good extreme pressure wear resistance as a lubricating oil additive.

The selected copper cyclohexyloxy borate (CuCHOB) can generate a friction degradation reaction in the friction process to generate reactants of Cu2O, B2O3 and the like to be deposited on the friction surface, thereby playing the roles of friction reduction and wear resistance.

The preparation method of the lubricating oil super-antiwear composite additive comprises the following steps: the components are mixed evenly according to different temperature steps.

The invention has the advantages of improving friction environment, reducing friction coefficient, improving sealing performance, improving transmission efficiency and improving bearing capacity. The lubricating oil super anti-wear compound additive has good compatibility and can be dissolved in various basic lubricating oils, such as: mineral oil, polyalphaolefin, polyether oil and vegetable oil.
