Abstract

An engine lubricating oil is prepared from, by weight, 3-5 parts of synthetic calcium alkylbenzene sulfonate, 4-9 parts of sorbitol, 3-6 parts of zinc butyloctyl primary alkyl thiophosphate, 4-8 parts of p-methoxystyrene, 1-5 parts of methyl silicone oil, 1-3 parts of sodium benzoate, 6-10 parts of pentaerythritol, 22-30 parts of base oil, 7-9 parts of zinc dialkyl dithiophosphate, 4-8 parts of sorbitan monoleate, 3-6 parts of sucrose ester, 3-5 parts of polydimethylsiloxane, 7-11 parts of glyceryl monostearate, 4-6 parts of triethanolamine and 1-3 parts of a surfactant. The engine lubricating oil has the advantages of very good lubricity, good toughness and strength of an oil film, and realization of normal use in high temperature and high pressure severe environment.

Description

A kind of engine oil

Technical field

The present invention relates to a kind of engine 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.Especially engine in the running, can not get suitable lubrication, will produce metal to-metal contact.Facts have proved, the heat that metal to-metal contact produces at short notice is enough to make melting of metal, causes the damage of parts even stuck.Therefore good lubrication must be given to the friction position in engine.When lubricating oil forms one deck oil film, reduce the resistance between friction parts, and oily film strength and toughness are the keys playing its lubrication.But existing lubricating oil toughness and insufficient strength, can not use under rugged environment, sometimes even can cause security incident.

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 engine oil, has good oilness, and the toughness of oil film and intensity are better, can High Temperature High Pressure etc. normally use under severe environment.

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

Alkylbenzene calcium alkylbenzenesulfonate 3-5 part, sorbyl alcohol 4-9 part, sulphur phosphorus fourth pungent primary alkyl zinc salt 3-6 part, p-methoxystyrene 4-8 part, methyl-silicone oil 1-5 part, Sodium Benzoate 1-3 part, tetramethylolmethane 6-10 part, base oil 22-30 part, zinc dialkyl dithiophosphate 7-9 part, sorbitan monooleates 4-8 part, sucrose ester 3-6 part, polydimethylsiloxane 3-5 part, single stearic acid glycerine lipoprotein 7-11 part, trolamine 4-6 part, tensio-active agent 1-3 part.

The invention has the beneficial effects as follows: engine oil of the present invention, have good oilness, the toughness of oil film and intensity are better, can High Temperature High Pressure etc. normally use under severe environment.
