Description

A kind of commonly-used internal combustion engine oil composition
The present invention relates to a kind of commonly-used internal combustion engine oil composition, especially a kind ofly can satisfy the lubricating oil compositions that medium-to-high grade vehicle vapour bavin is general, the summer in winter is general such as the car that uses in most of area and high-power supercharged diesel car.And performance with excellent especially inhibition oil product high temperature retrogradation.
As everyone knows, a kind of internal combustion (IC) engine oil composition is provided, make engine avoid causing accident such as can't run well because of machine oil retrogradation, serious wear, piston deposit too much are directed at sticking ring etc., and prolong engine work-ing life simultaneously, reducing maintenance cost is to improve a big task of oil product.
U.S. Pat 3243370 relates to a kind of internal combustion (IC) engine oil composition that can improve performances such as extreme pressure, wear-resistant, antioxygen.The feature of said composition is the material that contains following structure:

N=0-2 wherein, m=0-100; Y contains the functional group of one of array structure down :=P-, ≡ P=, ≡ P=S; R and R contain the functional group of array structure down: alkyl, halo alkyl, oxygen-containing hydrocarbon base, sulfur-bearing alkyl, sulfur-bearing halo alkyl; R and R " are to contain the down group of array structure: alkyl, haloalkyl, aryl, halogenated aryl, contain oxyalkyl, contain the oxygen haloalkyl; Z contains the down group of array structure: hydrogen and alkyl, and it is a unsaturated hydrocarbon radical, contains 1-17 carbon atom when n=2, contains 1-10 carbon atom when n<2; Z ' contains the group of array structure down: saturated hydrocarbyl, and when Z was the alkyl of 1-2 carbon atom, Z ' was a methyl, Z and Z ' are combined on the ring of hexanaphthene together by carbon atom when n=2.
Chinese patent CN 87 1 00331 A relate to a kind of internal combustion (IC) engine oil composition that contains transition metal that is used to control viscosity.Be characterised in that the oil soluble that used a kind of trace or the metal composites of oil-dispersing property in the said composition, its consumption is to be enough to block the speed that is caused by cigarette ash, its viscosity increases when oil is used for diesel engine, and metallide wherein contains a kind of metal that is selected from manganese, titanium, cobalt, chromium, vanadium, nickel, tungsten, copper and composition thereof.This patent has used aniline, phenylenediamine, thiazine, aniline-beta-naphthylamine, amino dodecane etc. as " promotor " of sneaking into excess metal.
Chinese patent CN 85 1 01591 A relate to and a kind ofly concoct the IC engine oil additive component that forms by a certain percentage by alkyl sodium salicylate, polyisobutene sulphur barium phosphate, polyisobutene succinimide and four kinds of additives of zinc dialkyl dithiophosphate.This component adds in the mineral oil of deep refining by a certain percentage can produce gasoline engine oil and pressurized diesel engine oil, but can not modulate the multi-grade oil that meets international norm.
As seen, the internal combustion (IC) engine oil composition of prior art, its high temperature oxidation resistance is dissatisfactory.And prescription is complicated, the inconvenience modulation.
Purpose of the present invention be intended to overcome the deficiencies in the prior art and provide a kind of high temperature oxidation resistance good, suppress the strong commonly-used internal combustion engine oil composition of high temperature retrogradation ability.
The object of the present invention is achieved like this: add an amount of dinonyldiphenylamine in base oil, can improve high-temperature oxidation resistance, strengthen the ability that suppresses the high temperature retrogradation.
What said base oil was a viscosity index at the paraffin base mineral oil of 80-100 and an amount of pour point depressant, kilfoam, viscosity index improver is compound.
The structure of dinonyldiphenylamine used in the present invention is:
Figure C9610906100041
It is the product by the reaction of pentanoic and nonene, wherein 4,4 '-content of dinonyldiphenylamine is not less than 70%.
Add the dinonyldiphenylamine of different amounts in HVI 200 base oils, the data that obtain are as shown in table 1.As seen the high-temperature oxidation resistance of the add-on of dinonyldiphenylamine and internal combustion (IC) engine oil composition has definite relation.Oxidation induction period is long more, shows that the oil oxidation performance is good more, and the ability that suppresses the retrogradation of oil product high temperature is strong more.

Dinonyldiphenylamine is a Lanzhou oil-refining chemical head factory product, and its add-on is the 0.1-2.0m% of internal combustion (IC) engine oil composition, the surplus base oil.
After adding dinonyldiphenylamine oxidation inhibitor, the oxide thin layer of oil product is significantly increased inductive phase, thereby satisfied of the requirement of III D testing of engine the high temperature oxidation polishing machine.
Further purpose of the present invention is when continuing raising high temperature oxidation polishing machine, to improve performances such as high temperature detergency, dispersiveness, provides a kind of and can satisfy the commonly-used internal combustion engine oil composition that diesel motor can satisfy the lubricated needs of petrol engine again.For this reason, in base oil, add following an amount of additive:
(A) dinonyldiphenylamine;
(B) the ester class is ashless;
(C) sulfonate;
(D) calcium sulfenyl phenolate;
(E) polyisobutene succinimide;
(F) zinc dialkyl dithiophosphate.
The high temperature oxidation polishing machine of the add-on of dinonyldiphenylamine and commonly-used internal combustion engine oil composition has definite relation; The adding that the ester class is ashless not only makes the dispersiveness of said composition improve, and the high-temperature behavior of said composition also is further improved; The adding of sulfonate and calcium sulfenyl phenolate is to have enough detergency, alkali retentivity and certain rustless property in order to ensure composition; The adding of polyisobutene succinimide is to have enough antioxygens, anticorrosive and abrasion resistance in order to ensure composition.
Zinc dialkyl dithiophosphate in the composition is the carrying out that stops oxidation by its degradation production, dinonyldiphenylamine then be with oxidation reaction process in the chain carrier reaction of transfer chain, make it become the torpescence material, play the effect that stops oxidizing reaction.Therefore dinonyldiphenylamine cooperatively interacts with the different mechanism of action with zinc dialkyl dithiophosphate and has stoped the high temperature oxidation of lubricating oil jointly, has given the high-temperature oxidation resistance of composition excellence.
The ester class that the present invention uses is ashless to be the mixture that polyisobutene dicarboxylic anhydride and tetramethylolmethane reaction generate.The structure of primary product is as follows: The I dibasic acid esters
