Abstract

A high temperature and oxidation resistant lubricating oil is prepared from, by weight, 2-3 parts of lanolin, 5-8 parts of phosphotriester, 3-5 parts of an extreme pressure anti-wear agent, 3-4 parts of trimethyl octane, 4-6 parts of polyethylene glycol, 4-5 parts of lupenyl palmitate, 23-46 parts of fatty alcohol polyoxyethylene ether, 2-4 parts of sulfurized calcium alkyl phenate, 3-13 parts of xylene, 6-7 parts of hydrophobically modified nanometer silicon oxide, 4-6 parts of polymethacrylate, 2-5 parts of dimethylaniline, 6-8 parts of sodium citrate, 3-7 parts of diatomite and 1-3 parts of phosphite. The high temperature and oxidation resistant lubricating oil has the advantages of normal work in high temperature environment, difficult oxidation and excellent oxidation resistance.

Description

A kind of resistant to elevated temperatures anti-oxidant lubricating oil

Technical field

The present invention relates to a kind of resistant to elevated temperatures anti-oxidant lubricating oil.

Background technology

Lubricating oil is used in all kinds mechanically to reduce friction, protection machinery and the liquid lubricant of workpiece, mainly play lubrication, cooling, antirust, clean, seal and the effect such as buffering.But lubricating oil is in storage and use procedure, it is inevitable for contacting with air and be oxidized, the time of contact is longer, temperature is higher, the degree of oxidation is darker, make some character of lubricating oil that irreversible change occur, as acid number increase, viscosity increases, throw out increases, darkens etc., these changes substantially reduce the work-ing life of oil product.So while the good lubricating properties ensureing lubricating oil, also more and more higher to the oxidation resistant requirement improving lubricating oil.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of resistant to elevated temperatures anti-oxidant lubricating oil, can normally work in high temperature environments, and not oxidizable, and has excellent antioxidant property.

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

Lanolin 2-3 part, phosphotriester 5-8 part, extreme pressure anti-wear additives 3-5 part, trimethylammonium octane 3-4 part, polyoxyethylene glycol 4-6 part, Lupenyl palmitate 4-5 part, fatty alcohol-polyoxyethylene ether 23-46 part, calcium sulfenyl phenolate 2-4 part, dimethylbenzene 3-13 part, nanoscale silicon 6-7 part of hydrophobically modified, polymethacrylate 4-6 part, xylidine 2-5 part, Trisodium Citrate 6-8 part, diatomite 3-7 part, phosphorous acid ester 1-3 part.

The invention has the beneficial effects as follows: resistant to elevated temperatures anti-oxidant lubricating oil of the present invention, can normally work in high temperature environments, and not oxidizable, and there is excellent antioxidant property.
