Description

A kind of anti-oxidant lubricating oil additive of improvement

Technical field

The present invention relates to a kind of anti-oxidant lubricating oil additive of improvement.

Background technology

The guarantee of quality of lubrication oil be unable to do without additive product, and additive is the main path improving quality of lubrication oil, expand lubricating oil kind, is also to improve lubricants performance, energy-conservation and reduce the important means of environmental pollution.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.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; a kind of anti-oxidant lubricating oil additive of improvement is provided; can be conducive to removing the metal-powder and other settling that are deposited on friction surface; there is splendid antioxidant effect and antirust, anti-corrosive function; improve effect and the quality of lubricating oil, can play a good protection to machine.

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

Calcium hydroxide 2-6 part, calcium chloride 0.3-0.5 part, magnesium alkylbenzene sulfonate 2-6 part, paraffin 3-4 part, methyl acrylate 20-40 part, calcium sulfenyl phenolate 4-12 part, tetramethylolmethane 5-6 part, alkyl benzene calcium sulfonate 3-7 part, sulphur phosphorus brothers alkyl zinc salt 12-18 part, glycerol acrylate 8-13 part, methyl acrylate 7-21 part, two salicylidene propylene diamine 4-8 part, polyisobutenyl succinic anhydride 3-6 part, triphenylphosphorothionate 0.8-1.6 part, purification agent 1-2 part, rust-preventive agent 0.5-1 part, viscosity index improver 2-6 part, oxidation inhibitor 0.8-1.2 part.

The invention has the beneficial effects as follows: the anti-oxidant lubricating oil additive of improvement of the present invention; can be conducive to removing the metal-powder and other settling that are deposited on friction surface; there is splendid antioxidant effect and antirust, anti-corrosive function; improve effect and the quality of lubricating oil, can play a good protection to machine.
