Abstract
The invention provides a lubricating oil additive. The lubricating oil additive consists of the following components in parts by weight: 0.2-0.5 part of a pour point depressant, 0.3-0.8 part of an antioxidant, 0.01-0.05 part of an antifoaming agent, 3-8 parts of a viscosity improver and 0.2-0.3 part of an anti-wear agent. The pour point depressant is olefin or acrylic ester; the antifoaming agent is a compound antifoaming agent; the anti-wear agent is sulfurized grease, phosphate or metal dithiophosphate; and the viscosity improver is polyisobutene. The lubricating oil additive has the beneficial effects of high compatibility with base oil, stable performance and long service life, and the driving safety is enhanced.
Description
Technical field
The present invention relates to lubricating oil field, especially a kind of lubricating oil additive.
Background technology
Lubricating oil additive concept is one or more compounds added in lubricant, obtains certain new characteristic or improve more existing characteristics in lubricant to make lubricant.Additive divides by function types such as mainly containing antioxidant, anti-wear agent, friction modifier (having another name called oiliness improver), extreme-pressure additive, purification agent, dispersion agent, froth suppressor, corrosion prevention rust preventer, flow point activator, viscosity index improver.
Along with the fast development of automobile industry, automobile energy consumption and environmental issue cause everybody concern.In automobilism situation, lubricated sliding wear situation on the energy consumption of automobile and environmental protection impact the most remarkable, therefore, the lubricity of lubricating oil, stability are had higher requirement.
Summary of the invention
The invention provides a kind of lubricating oil additive, significantly can improve the indices of lubricating oil.
For realizing above-mentioned goal of the invention, the embodiment that the present invention takes is as follows:
A kind of lubricating oil additive, it is composed of the following components, according to weight parts: pour point depressant: 0.2-0.5 part; Oxidation inhibitor: 0.3-0.8 part; Kilfoam: 0.01-0.05 part; Viscosity modifier: 3-8 part; Anti-wear agent 0.2-0.3 part.
Preferably, pour point depressant: 0.2-0.4 part; Oxidation inhibitor: 0.3-0.5 part; Kilfoam: 0.01-0.03 part; Viscosity modifier: 4-8 part; Anti-wear agent 0.2-0.3 part.
Preferably, described pour point depressant is alkene or acrylate, and kilfoam is composite anti-foam agent, and anti-wear agent is sulfuration grease, phosphoric acid ester or metal dithiophosphate, viscosity modifier polyisobutene.
The invention has the beneficial effects as follows: 1, good with base oil consistency, stable performance; 2, long service life, adds travel safety.
