Abstract

The invention relates to lubricating oil for an automobile. The lubricating oil is prepared from the following raw materials in parts by weight: 6-10 parts of naphthenic oil, 3-8 parts of iso-tridecanol polyoxyethylene ether, 4-7 parts of n-butyl acetate, 4-8 parts of sodium sebacate, 1-5 parts of zinc butyl octyl dithiophosphate, 2-6 parts of polyalkoxy polyol, 5-10 parts of sulfurized calcium alkyl phenolate, 5-8 parts of trilinolein, 2-7 parts of trimethyl octane, 3-9 parts of polytetrafluoroethylene, 1-4 parts of almond oil and 4-8 parts of long chain polyamides. The lubricating oil provided by the invention has the beneficial effects that the lubricating oil has the characteristics of high-temperature resistance and strong bearing capacity, is used for effectively reducing machinery friction and also can be used for preventing rust and corrosion and reducing vibration.

Description

A kind of lubricating oil for automobile

Technical field

The present invention relates to a kind of lubricating oil for automobile.

Background technology

Motor oil is divided into mineral lubricating oils, ucon oil, a few class of semi-synthetic lubrication wet goods.Its effect mainly contains: 1) lubricate anti-attrition: between piston and cylinder, all there is relatively sliding fast between main shaft and bearing shell, prevent the wearing and tearing that part is too fast, then need to set up oil film between two sliding surfaces.There is the oil film of adequate thickness to be separated by the piece surface of relatively sliding, thus reach the object reduced wear.2) cool: heat can be taken back sump and be distributed in air again and help water tank cooled engine by machine oil.3) cleaning is clean: the carbide on engine part, greasy filth, wear metal particle can be led to circulation by good machine oil takes back sump, foul part time job face produced by the flow wash of lubricating oil.4) sealing and anti-leakage: machine oil can form a sealing-ring between piston ring and piston, reduces the leakage of gas and prevents extraneous pollutent from entering.5) antirust corrosion protection: the absorption of lubricating oil energy is in the contact of the anti-sealing of piece surface, air, acidic substance and obnoxious flavour and part.6) damping, buffering: when engine cylinder mouth pressure sharply rises, the load aggravated suddenly on piston, piston bits, connecting rod and crankbearing is very large, and this load makes the impact load born play the effect of buffering through the transmission lubrication of bearing.

Summary of the invention

For the deficiencies in the prior art, technical problem to be solved by this invention is, provides a kind of lubricating oil, has high temperature resistant, that supporting capacity is strong feature, effectively reduces friction mechanically, simultaneously can antirust corrosion protection, reduces vibrations.

For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of lubricating oil for automobile is made up of the raw material of following parts by weight:

Naphthene base crude oil 6-10 part, isomerous tridecanol polyoxyethylene ether 3-8 part, n-butyl acetate 4-7 part, sebacic acid sodium 4-8 part, sulphur phosphorus Ding Xinjixin salt 1-5 part, poly-alkoxyl group many alcohol 2-6 part, alkyl monosulfide powder calcium 5-10 part, Trilinoleyl glyceride 5-8 part, trimethylammonium octane 2-7 part, tetrafluoroethylene 3-9 part, Prunus amygdalus oil 1-4 part, long-chain polynary acid amides 4-8 part.

The invention has the beneficial effects as follows, lubricating oil of the present invention to there is high temperature resistant, that supporting capacity is strong feature, effectively reduce friction mechanically, simultaneously can antirust corrosion protection, reduce vibrations.
