[0031] The preparation method of viscosity reducing active agent is:

[0032] S1. Take zirconium n-butoxide at a mass ratio of 1~3:2~5 and add cage-type octapoly(trimethylsiloxy)silsesquioxane to mix to obtain a mixture. Take the mixture at a mass ratio of 2~5:10 Add absolute ethanol at ~15 minutes, stir and mix for 20-30 minutes to obtain a mixed solution, take the mixed solution and add it dropwise to deionized water at a mass ratio of 1~3:3~5, control the dropping time for 30~60 minutes, and stir and mix for 2~4 hours , centrifuged, the precipitate was taken and dried, ground and pulverized through an 80-mesh sieve, and the sieved particles were collected;

[0033] S2. Take the sieved particles and add tetraethyl silicate according to the mass ratio of 1~5:10~15, add a catalytic active agent with a quality of 90~95% of tetraethyl silicate, stir and mix for 20~30min to obtain mixture a, take Add deionized water to mixture a according to the mass ratio of 10~15:5~9, stir and...

Abstract

The invention discloses an extreme-pressure-resistant anti-wear agent and a preparation method thereof, and belongs to the field of lubricating oil additives. Tetraethyl silicate and the like are added into the prepared viscosity reducing active agent to form the viscosity reducing active agent with an acidic catalytic center, and the viscosity reducing active agent is modified by ammonium persulfate, so that the catalytic effect is enhanced, the viscosity of an oil base is reduced, the flowability is improved, and the wear resistance is improved; the nano additive prepared by the invention isoxidized by adding hydrogen peroxide and then is acidified, and soft metal is used for forming wear self-repairing on a friction interface, so that the nano additive has relatively high wear resistance; the interfacial polarity regulator prepared by the invention is matched with hexadecyl trimethyl ammonium bromide and isooctane to increase the solubility and reduce the surface tension, so that the anti-wear agent can well permeate into an interface, and the anti-wear efficiency is improved; the oil base viscosity is reduced through the viscosity reducing active agent, combustion is promoted,carbon deposition is reduced, and the effects of reducing energy consumption and prolonging the service life of the anti-wear agent are achieved. The anti-wear agent solves the problem that the existing anti-wear agent cannot reduce friction loss and oil consumption.

Description

technical field [0001] The invention belongs to the field of lubricating oil additives, and in particular relates to an extreme pressure and antiwear agent and a preparation method thereof. Background technique [0002] In the prior art, when the metal surface bears a high load, a large number of metal surfaces are in direct contact, generating a large amount of heat, and the additive can chemically react with the metal surface to form a chemical reaction film, which acts as a lubricant and prevents the metal surface from being scratched. Even welding. This most severe boundary lubrication is usually called extreme pressure lubrication, and this additive is called extreme pressure antiwear agent. When the industrial hydraulic oil, gear oil, and turbine oil in the domestic and foreign markets are used, the lubrication effect is not good, the parts wear heavily, the temperature rises, the accumulation of sludge is formed quickly, and the service life of the oil is short and t...
