Abstract
The invention discloses a kind of lubricating oil additive based on methanol gasoline, the thiophene-based metal organic sulfonate of the sulfur-bearing that the following general formula containing 40 ~ 60wt% represents;
Description
Technical field
The present invention relates to lubricating oil additive, particularly relate to a kind of alcohol resistance lubricating oil additive.
Background technology
Methanol gasoline has good development prospect, but carbinol gasoline fuel automobile runs into many problems when using lubricating oil.
1. from the angle of engine oil, methanol gasoline has higher vaporization heat, single boiling point and lower vapour pressure because of it, affect the dynamic performance of engine at a lower temperature and cause engine oil quality to worsen rapidly, thus engine scuffing is aggravated; Methanol gasoline also can cause viscosity index improver in engine oil be precipitated out from engine oil and generate greasy filth; Methyl alcohol generates acid stronger material in combustion, neutralizes, rapidly the purification agent of consumption of engine oil with the alkaline purification agent in engine oil.
2. from methanol gasoline to engine oil detergent-dispersant performance angle, methanol gasoline and the generation of products of combustion to engine oil colloid thereof have a significant impact.Along with the increase of methanol content in methanol gasoline, coking amount is also in increase; Methanol gasoline and products of combustion thereof can cause the high/low temperature dispersion coefficient of gasoline engine oil to reduce; Methanol gasoline is to the oxidation corrosion resistance of engine oil, and resistance to emulsion etc. also all have a certain impact.
Wherein detergent-dispersant performance, resistance to abrasion, antioxygen resists nitrated property can be solved by the rank improving gasoline engine oil, but high-level gasoline engine oil is high as the engine oil cost compare of methanol gasoline, and the demulsification performance of testing high-level gasoline engine oil when showing burning methanol gasoline does not reach requirement, this will hinder China's spread methanol gasoline.Burning feature based on methanol gasoline and the requirement to engine oil, the engine oil of applicable methanol gasoline burning feature must be worked out, and the performance of methanol gasoline engine oil is higher than the gasoline engine oil used at present, consider the Cost Problems that additive dosage causes, the cost of methanol gasoline engine oil also should lower than now using machine oil simultaneously.
Patent CN 1197943C considers the feature of alcohol fuel, provides a kind of additive composition for lubricant oil.Patent CN 100344739C discloses a kind of lubricating oil composition being mainly concerned with high-grade diesel motor.These two kinds of lubricating oil are all not suitable for methanol gasoline.
Patent CN 101358155A provides a kind of lubricating oil composition for methanol gasoline engine, be made up of purification agent, oxidation inhibitor, ashless dispersant and some polymer oil products, although bibliographical information its there is good power increase and low fuel consumption, but as a kind of functional additive of engine oil, add-on is large, is unfavorable for large-scale popularization in methanol gasoline.
Lubricating oil Lanzhou, the Kunlun research and development centre is the property adapting to Novel methanol gasoline, and carry out the research of supporting lubricating oil, nearest methanol gasoline lubricating oil is developed successfully always.It is reported through test, the SJ methanol gasoline engine special lube of the Kunlun lubricating oil development meets the lubricating requirement of methanol gasoline engine completely.This new lubricant carries out in the test of 12000km road travel on methanol gasoline (M100) taxi, has more excellent acid neutralization capacity and base number hold facility relative to regular engine oil, has better anti-oxidant, wear-resistantly to undermine demulsification performance.
Summary of the invention
The object of this invention is to provide a kind of lubricating oil additive based on methanol gasoline, use it on the vehicle of burning methanol Fuel Petroleum, be applicable to various base oil, significantly increase the lubricity of methanol fuel power system, environmental protection and energy saving.
For achieving the above object, the present invention screens component each in lubricating oil additive, except considering the performance of each component function additive self and advantage, simultaneously using the consistency of additive and base oil, to the elimination of the corrodibility of methanol gasoline, methanol oxidation thing as top-priority condition.
Of the present inventionly to contain based in the lubricating oil additive of methanol gasoline:
1) the thiophene-based metal organic sulfonate of sulfur-bearing that represents of the following general formula of 40 ~ 60wt%, in order in and the acidic cpd that generates after methanol fuel burning;
Wherein, R is C
1-C
4alkyl, C
1-C
4alkoxyl group; M is Ca, Mg, Zn, K or Na; N is 1 or 2;
2) at least a kind of organophosphorus compounds material of content 20 ~ 30wt%, using as wear-resistant getter;
3) mineral oil of content 20 ~ 30wt%, as thinning oil to improve the consistency of each component simultaneously as reaction solvent.
Wherein, described organophosphorus compounds material comprises tritolyl phosphate, triphenylphosphate, triethyl phosphate, tributyl phosphate and/or di-n-butyl phosphite.
Meanwhile, the lubricating oil addO-on therapy of other routines can also be contained in the above-mentioned lubricating oil additive of the present invention as detergent for lubricating oil, dispersion agent, rust remover, antioxidant etc.
The thiophene-based metal organic sulfonate of described sulfur-bearing and organophosphorus compounds material add in mineral oil by the preparation method of lubricating oil additive of the present invention in proportion, be warming up to 80 ~ 120 DEG C of stirring reactions 2 hours, be slow cooling to 40 ~ 60 DEG C to stir 5 ~ 8 hours, to system clear.
The present invention is as a kind of lubricating oil additive, and the addition in regular engine oil is 20 ~ 50wt%, significantly can improve the dynamic property of burning methanol gasoline vehicle and solve the vehicle lubricating system problem that burning methanol fuel brings.
The results showed; lubricating oil additive of the present invention can meet the lubrication needs of methanol gasoline engine within the normal oil draining period; can overcome again use methanol gasoline rear engine lubricating oil to turn white, bubble, emulsification and the phenomenon such as thinning; ensure the normal operation of engine, increase the service life.
Lubricating oil additive of the present invention is prepared easy, for the dynamic property of burning methanol fuel especially high-proportion methanol fuel vehicle and oilness provide solution.
