The invention provides a kind of lubricating oil additive that is used to burn pure and mild alcohol fuel oil engine, this additive comprises that main amount is the organic amine component that is selected from primary aromatic amine, aromatic amine, Armeen, secondary aliphatic amine, alicyclic primary amine and their mixtures, and a spot of phosphoric acid ester.Composition comprises about 68.75 weight % this phosphoric acid ester to this amine component and about 25.0 to the 31.25 weight % of 75.0 weight % preferably.Lubricating oil is formed and is comprised internal combustion (IC) engine lubricating oil and this lubricating oil additive.The present invention also provides and has prepared the method that this lubricating oil is formed, and uses this lubricating oil to form the method for inhibition corrosion and excessive engine wearing and tearing.
Description
The invention provides the high-content that is applicable to ordinary internal combustion engine lubricating oil peace and quiet/disperse lubricating oil additive, thereby make lubricating oil can be used to burn alcohol or alcohol fuel, methyl alcohol for example, the oil engine of alcohol fuel.The present invention also provides the lubricating oil component that contains this lubricating oil additive, prepares the method for this lubricating oil component, and uses this emollient component to suppress engine corrosion and over worn method.
Because excessive engine wearing and tearing and lubrication oil consumption speed constantly increase, the lubricating oil that general engine uses is invalid in burning pure engine.One of reason is that the chemical reactivity of gasoline and the products of combustion of alcohol in engine fuel system has bigger difference.In pure fuel system, a large amount of lubricating oil generation DeRs, and this phenomenon can not occur in the Fuel Petroleum system.These chemical reactions cause increasing the corrosion of pure fuel system, and for example methyl alcohol is oxidized to formaldehyde and formic acid easily, and this reaction is represented with formula 1:
The vehicle of many use methanol fuels is because the formic acid that the methyl alcohol burning produces makes the piston Ministry of worker be subjected to excessive corrosion and bearing wear.Organic amine additive in formic acid and the engine oil commonly used reacts, and this additive plays antioxidant, the effect of corrosion inhibitor and anti-wear agent.In the amine additive and formic acid.Yet general additive it seems can not be fully in and the formic acid that generated of methyl alcohol burning.These reactions are represented with formula 2 formulas 3:
Easy and the amine additive reaction of formaldehyde.
Formaldehyde with as antioxygen, the reaction of the amine of antiacid and ashless dispersant.The formaldehyde reaction of formula 4 expressions is facilitated the degraded of oil in the methanol fuel system greatly.
Additive is owing to be consumed easily with formaldehyde and formic acid reaction, the lubricating oil additive that needs a kind of minimizing as far as possible and formaldehyde and formic acid reaction for the life-span that prolongs lubricating oil additive, equally, require lubricating oil additive can reduce the overreaction that oxidation of ethanol becomes acetaldehyde and Yi Suan And and reduces these components as far as possible as far as possible.
In pure fuel system, another major issue is a zinc dialkyl dithiophosphate, and it is a kind of main multifunction additive in most of all-purpose engine oils, and it easily transesterification takes place and loses its antiwear characteristics morely.Ester group reaction relates to the alkyl of alcohol, for example methyl alcohol or ethanol, and at ester, dialkyl group thiophosphoric acid zinc for example exchanges and generates new ester with former.React with formula 5 expression ester groups:
Transesterification is an acid catalyzed reaction, thus can occur in the aldehyde that produces in alkaline additive amine in lubricated and the combustion processes or Suan anti-Ying And depleted after.Transesterification is not the main course of oily DeR in the hydrocarbon fuel system, but transesterification is the main course of oil degraded in methyl alcohol and other fuel system.For example when methyl alcohol or ethanol and gasoline fusion, the amount of transesterification is proportional to the amount of alcohol in mixture.
Another factor that causes the corrosion aggravation in burning pure engine is that the solubleness of carbonic acid gas in alcohol becomes big.For example carbonic acid gas is dissolved in the methyl alcohol than water is easier.Water and methyl alcohol usually are to be present in part cold in the crankcase as products of combustion.Water and fuel combustion product, for example SO
3, NO
2And CO
2Reaction generates corresponding acid, sulfuric acid, and nitric acid and carbonic acid, with formula 6,7,8 expressions.
It is to cause oil engine corrosive one of the main reasons that acid is reacted with full genus in engine.The alkaline additive that is usually used in lubricating oil in the hydrocarbon fuel system, for example organic amine and alkali metal compound these acid that neutralized effectively.But because the solubleness of carbonic acid in alcohols is big, thereby the content ratio of carbonic acid is high in petrol system in methyl alcohol or other pure fuel system.From products of combustion NO
2The nitric acid that is generated also may be like this.The absorption of carbonic acid gas is the unexpected high major reason of pure fuel corrosion.
Lubricating oil analysis shows that the wear-resistant component that contains sulfonate, naphthenate or other alkaline metal salt generates insoluble alkaline carbonate precipitation owing to fallen by mass consumption with the carbonic acid reaction.Formula 9 and 10 expression precipitin reaction.
Compete with the reacting phase of carbonic acid in precipitin reaction and the organic amine.Though the faster and easier generation of neutralization reaction, the reaction of an alkali metal salt is consumed along with organic amine and accelerates.Therefore require not carry out too soon with the reaction of formic acid or acetate and carbonic acid in the organic amine in the lubricating oil additive, thereby be reduced in the possibility that alkaline metal salt is consumed in formula 9 and 10 precipitin reaction of representing.
General objective of the present invention provides a kind of lubricating oil additive be used to burn oil engine , And of pure fuel and can protect because engine corrosion and the wearing and tearing that pure fuel causes.

Above-mentioned all compounds can have been bought on market.Lubricating oil additive of the present invention is by the more a spot of lubricating oil additive of fusion, and this additive mainly contains organic amine, can be selected from Armeen, secondary aliphatic amine, alicyclic primary amine, primary aromatic amine, aromatic amine and their mixture and more a spot of phosphoric acid ester and relatively large lubricating oil adulterant and be made into.This lubricating oil adulterant should meet Apl to the minimum requirements of SF/CO level oil or meet the oil of CCMC2.2 service rating or be selected from single or many its SAE of viscosity grade and be about mineral oil or any other lubricating oil adulterant of synthetic wet goods of 5 to 50.The present invention's lubricating oil additive preferably is an above-mentioned amine by about 1.0 to the 8.0 weight % of fusion, and the above-mentioned lubricating oil adulterant of the above-mentioned phosphoric acid ester of about 0.25 to 2.5 weight % and about 89.5 to 98.75 weight % is made into.
Lubricating oil additive of the present invention can be by adding the middle use of more changing oil of similar 1 quart of additive to 5 quart.Lubricating oil additive of the present invention can effectively prevent owing to engine corrosion and the wearing and tearing of using methyl alcohol, ethanol or other alcohol and alcohol fuel to cause.Changing oil to travel at every turn surpasses 4,000 miles, can reach 6,000 miles in some cases.
Phosphoric acid ester is right-tricresyl alkaliine preferably, or the mixture of tricresyl alkaliine isomers, it can as methyl alcohol or alcoholic acid add Rong Ji And to the methyl alcohol in the lubricating oil and ethanol alcohol dripped ashless peace and quiet/effect of dispersion agent, such solubilizing agent need be used to dissolve or disperse phase is worked as a large amount of alcohol, for example methyl alcohol or ethanol.These alcohol are in the engine of the pure fuel of burning, are directed in the lubricating oil in combustion processes.Phosphoric acid ester Jia Rong And disperses methyl alcohol or alcoholic acid alcohol to drip therefore, can prevent to occur on the moving parts of oil engine the dry friction point.When lacking phosphoric acid ester, methyl alcohol or ethanol are insoluble in the hydro carbons lubricating oil, may dry friction point occur and cause excessive engine wearing and tearing.
Phosphoric acid ester plays anti-wear agent , And equally and when using methyl alcohol or alcohol fuel, it is better than general zinc dialkyl dithiophosphate anti-wear agent.Zinc dialkyl dithiophosphate almost is general general in petrol engine.But in combustion methanol or ethanol oil engine, lose its antiwear characteristics owing to transesterification takes place rapidly for it and alcohol.
Amine component plays a part alkaline additive, and neutralization is because methyl alcohol, formic acid, acetate and the carbonic acid gas of alcoholic acid oxidation and corresponding generation and the carbonic acid of water reaction generation.Amine component also plays a part oxidation inhibitor, reduces methyl alcohol or oxidation of ethanol as far as possible and becomes their corresponding aldehyde or acid.
In lubricating oil additive of the present invention, contain the larger amt organic amine of (being about 68.75 to 75.0 weight %), can prepare the lubricating oil that contains 1.0 to the 8.0 weight % organic amines of having an appointment, therefore and the lubricating oil that contains the plain oil additive by contrast only contains about 0.25% organic amine, can reduce for example consumption of naphthenate and sulfonate of alkaline metal salt as far as possible.During the reaction of alkaline metal salt and carbonic acid, generate insoluble carbonate and consume this reaction and the competition of neutralizing acid reacting phase.Faster And of neutralization reaction and easier generation, but after organic amine was consumed, precipitin reaction had just become a problem that will solve.When more organic amine exists, more carbonic acid is neutralized, this just reduced can and the quantity of the carbonic acid that reacts of an alkali metal salt.
Analysis is used lubricating oil in motor car engine, provides a kind of and be as short as the method for indication engine scuffing convenient and reliable in thousands of miles the mileage in the oil draining period.
And certain miles per hour that travelled is used the spectrometry oil sample behind engine oil change, and lubricating oil additive can be estimated according to wear elements, for example iron, lead, copper, chromium, nickel, tin, aluminium and molybdenum.Normal wear and because the excessive corrosion or the damage of some metal engine parts, these metals or wear elements are high in the lubricating oil.
Because the extensive variation of engine material is difficult to use the method for accurately measuring wearing and tearing constituent content numerical value in the used oil to point out the excessive abrasion of engine technically.But the data of wearing and tearing element can be used as the universal standard of evaluation lubricating oil and have listed in table 1.Provided in engine first and second sources of each wearing and tearing element, also provided the mean value with each wearing and tearing element of 1,000,000/expression, above numerical value ties up in the later oil of break-in (break-in) point and break-in point and records.Between run-in period, the wearing and tearing of engine are quite high, after engine break-in, have reached steady Zhuan Tai And and have kept stablizing about 50,000 miles, and this depends primarily on concrete vehicle and its maintenance situation.The break-in point of general engine is generally in 0 to 10,000 mile scope.Judgement criteria in the table 1 can be used for estimating the data in embodiment 1 to 13.
The most useful index of expression excessive engine wearing and tearing is when analyzing used oil, and it is big that a certain wear elements becomes suddenly.These content analysis data are to decide under the engine constant load with specific oily resulting.
Base number is a kind of tolerance of the peace and quiet and resistance to corrosion of oil, the base number of new engine oil normally 4 to 5, and base number is 1 or lowlyer shows that contained additive has been depleted to dangerous degree in any oil.It has been generally acknowledged that in petrol engine the base number of oil is, the protection of enough surpluses can be provided engine at 2 o'clock.
