Description

A kind of lubricating oil additive with antioxidant effect

Technical field

The present invention relates to a kind of lubricating oil additive with antioxidant effect.

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.The quality of lubricating oil additive to lubricating oil has a great impact, and such as must make with lubricator (as paraffin base lubricating oil) to lubricate their moving parts as the engine of fuel with oil fuel, kerosene, gasoline, Sweet natural gas or artificial gas, liquefied gas etc.Lubricating oil in use will contact with air, various mechanical means also can produce heat, friction spot temperature in running is raised, in addition, various metal materials in equipment, as copper, iron etc. all can play the deterioration by oxidation that oil product is accelerated in katalysis, are finally that lubricating oil viscosity increases, generate acidic substance corroding metals material, also can generate various charcoal shape or pitch shape sedimentable matter as blocking pipelines such as paint films.All these changes all normally run the continuation use of oil product and equipment and bring disadvantageous effect.Therefore require that oil product has good antioxygen and anti-corruption effect.In oil product, add antioxygen and anticorrosion additive, its objective is the oxidising process suppressing oil product, passive metal, to the katalysis of oxidation, plays and extends the object that oil product used and protected machine.But lubricating oil additive is all generally the combination product of single additive in the market, its character is unstable, easily reduces the result of use of lubricating oil, and can not play the effect in the work-ing life extending oil product, awaits further raising.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provide a kind of lubricating oil additive with antioxidant effect, antioxygenation is splendid, effectively prevents oil product aging, ensures that lubricating oil is long-lasting, stable in properties.

For solving prior art problem, technical scheme provided by the invention is, a kind of lubricating oil additive with antioxidant effect, and it is made up of the raw material of following parts by weight:

Sulphur phosphorus brothers alkyl zinc salt 10-24 part, polyisobutylene succinamide 2-4 part, polyisobutylene succinamide 0.5-1.2 part, dialkyl benzene sulfonic acids calcium 3-6 part, TriMethylolPropane(TMP) 1-4 part, calcium sulfenyl phenolate 5-10 part, dialkyl benzene sulfonic acids calcium 2-4 part, alkylbenzene calcium alkylbenzenesulfonate 5-8 part, thiodiphenylamine 2-4 part, calcium phosphate 2-5 part, tetramethylolmethane 4-7 part, base oil 14-23 part, olein 2-5 part, tung oil 3-4 part, 124 Triazole amine 2-5 part, alpha-olefin copolymer pour point depressant 1.4-2 part, dispersion agent 1.5-2.3 part, emulsion splitter 0.15-0.3 part, oxidation and corrosion inhibitor 0.7-1 part.

The invention has the beneficial effects as follows: the lubricating oil additive with antioxidant effect of the present invention, antioxygenation is splendid, effectively prevents oil product aging, ensures that lubricating oil is long-lasting, stable in properties.
