Abstract
The invention belongs to the technical field of lubricant additive materials, and in particular relates to a lubricant additive with extreme pressure resistance as well as preparation and application methods of the lubricant additive. The lubricant additive is composed of base oil, a metallic sulfur-containing compound and a dispersing agent, wherein the metallic sulfur-containing compound is of an atomic-scale single layer structure. The lubricant additive is simple in preparation method, convenient and easy to implement, economical and practical, and stable in performance. As the lubricant additive is used, a layer of protective film composed of nanoscale solid particles and organic matters together is formed on the surface of a friction pair and is tightly bonded on the surface of the friction pair, i.e., the protective film has small possibility of shedding and can prevent direct contact of the friction pairs so as to reduce friction and avoid abrasion. Thus, the extreme pressure resistance of a lubricant is greatly improved.
Description
Technical field
The invention belongs to lubricating oil additive field of material technology, particularly a kind of lubricating oil additive and preparation and application method thereof with anti-extreme pressure property.
Background technology
Reasonable employment lubricating oil additive effectively can improve the lubricity of lubricating oil, improves the friction environment of friction pair, thus realizes protection friction pair, reduces friction, the objects such as save energy.The mechanical means run under high temperature heavy load environment, its lubrication mode often belongs to boundary lubrication category, uses rational lubricating oil additive in this case, and especially extreme-pressure additive just seems particularly important.And use nanoscale solids particle as lubricating oil additive, good anti-extreme pressure property can be obtained.
Nanoscale solids particle is used to have more bibliographical information as lubricating oil additive, but, have no precedent the report of sulfur-bearing metallic compound as lubricating oil additive about using atomic monolayer.
Summary of the invention
Not enough for prior art, the invention provides a kind of lubricating oil additive and the preparation and application method thereof with anti-extreme pressure property.
There is a lubricating oil additive for anti-extreme pressure property, each component of described lubricating oil additive and massfraction as follows: base oil 50% ~ 90%, sulfur-bearing metallic compound 1% ~ 20%, dispersion agent 1% ~ 30%; The structure of described sulfur-bearing metallic compound is atomic monolayer structure.
Described base oil is one or more in the I class oil, II class oil, III class oil, IV class oil and the V class oil that belong to API (American Petroleum Institute) and specify.
Described base oil is one or more in whiteruss (white oil), polyalphaolefin (PAO), Esters oil and vegetables oil.
The granularity of described sulfur-bearing metallic compound is 1 nanometer to 100 nanometer.
Described sulfur-bearing metallic compound is one or more in moly-sulfide, tungsten sulfide, lead sulfide and selenium sulfide.
Described dispersion agent is the long-chain organism containing amino or hydroxyl.
Described dispersion agent is one or more in oleyl amine and derivative, stearylamine and derivative thereof and oleic acid and derivative thereof.
Have a preparation method for the lubricating oil additive of anti-extreme pressure property, joined by dispersion agent in base oil, heated and stirred makes it be dissolved into uniform liquid; Then sulfur-bearing metallic compound is added in above-mentioned mixing liquid; Carry out supersound process again, sulfur-bearing metallic compound is uniformly dispersed.Wherein base oil and dispersion agent are on sale on the market, sulfur-bearing metallic compound can to chemically (as Altavilla, C., M.Sarno and P.Ciambelli, A Novel Wet Chemistry Approach for the Synthesis of Hybrid 2D Free-Floating Single or Multilayer Nanosheets of MS2@oleylamine (M=Mo, W) .CHEMISTRY OF MATERIALS, 2011.23 (17): p.3879-3885. described method) or mechanical means (as Coleman, J.N., et al., Two-Dimensional Nanosheets Produced by Liquid Exfoliation of Layered Materials.Science, 2011.331 (6017): p.568-571. described method) prepare.
There is an application method for the lubricating oil additive of anti-extreme pressure property, by described lubricating oil additive with account for lubricating oil capacity or quality 1% ~ 30% ratio join in lubricating oil, stir use.
