By adding 20-50wt% of lubricant additive into common machine oil, the power performance of methanol gasoline burning vehicles can be obviously improved, and the problem of a vehicle lubricating system caused by methanol fuel burning can be solved.
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 at a lower temperature the dynamic performance of engine and cause engine oil quality to worsen rapidly, thereby make engine scuffing aggravation; Methanol gasoline also can cause viscosity index improver in engine oil from engine oil, to be precipitated out and to generate greasy filth; Methyl alcohol generates acid stronger material in combustion processes, with the alkaline purification agent neutralization in engine oil, the rapidly purification agent of consumption of engine oil.
From methanol gasoline to engine oil detergent-dispersant performance angle, methanol gasoline and products of combustion thereof have a significant impact the generation of engine oil colloid.Along with the increase of methanol content in methanol gasoline, coking amount is also increasing; Methanol gasoline and products of combustion thereof can cause the high low temperature dispersion coefficient of gasoline engine oil to reduce; The oxidation corrosion resistance of methanol gasoline to engine oil, resistance to emulsion etc. also all have a certain impact.
Detergent-dispersant performance wherein, resistance to abrasion, the anti-nitrated property of antioxygen can solve by improving the rank of gasoline engine oil, but high-level gasoline engine oil is high as the engine oil cost compare of methanol gasoline, and when experiment shows burning methanol gasoline, the demulsification performance of high-level gasoline engine oil does not reach requirement, and this will hinder China's spread methanol gasoline.Burning feature based on methanol gasoline and the requirement to engine oil, must work out the engine oil that is applicable to methanol gasoline burning feature, and the performance of methanol gasoline engine oil will be higher than the gasoline engine oil using at present, consider the Cost Problems that additive dosage causes, the cost of methanol gasoline engine oil also should be lower than now using machine oil simultaneously.
Patent CN 1197943C considers the feature of alcohol fuel, and a kind of additive composition for lubricant oil is provided.Patent CN 100344739C discloses a kind of lubricating oil composition that is 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, by purification agent, oxidation inhibitor, ashless dispersant and some polymer oil products, formed, although it has good increased power and low fuel consumption bibliographical information, but the functional additive of using as a kind 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, for adapting to the property of novel carbinol gasoline, carries out the research of supporting lubricating oil always, and methanol gasoline lubricating oil is developed successfully recently.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, with respect to regular engine oil, having better acid neutralization capacity and base number hold facility on methanol gasoline (M100) taxi, has better anti-oxidant, the wear-resistant demulsification performance that undermines.
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, applicable to various base oils, significantly increase the lubricity of methanol fuel power system, environmental protection and energy saving.
For achieving the above object, the present invention screens each component in lubricating oil additive, except considering the performance and advantage of each component function additive self, 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.
In lubricating oil additive based on methanol gasoline of the present invention, contain:
1) the thiophene-based metal organic sulfonate of the sulfur-bearing that the following general formula of 40 ~ 60wt% represents, 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%, usings as wear-resistant getter;
3) mineral oil of content 20 ~ 30wt%, as thinning oil using improve each component consistency simultaneously as reaction solvent.
Wherein, described organophosphorus compounds material comprises tritolyl phosphate, triphenylphosphate, triethyl phosphate, tributyl phosphate and/or di-n-butyl phosphite.
Meanwhile, in the above-mentioned lubricating oil additive of the present invention, can also contain other conventional lubricating oil and add component as detergent for lubricating oil, dispersion agent, rust remover, antioxidant etc.
The preparation method of lubricating oil additive of the present invention adds in mineral oil by the thiophene-based metal organic sulfonate of described sulfur-bearing and organophosphorus compounds material in proportion, be warming up to 80 ~ 120 ℃ of stirring reactions 2 hours, be slow cooling to 40 ~ 60 ℃ and 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%, can significantly 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 that methanol gasoline rear engine lubricating oil turns white, foaming, emulsification and the phenomenon such as thinning; guarantee the normal operation of engine, increase the service life.
Lubricating oil additive of the present invention is prepared easy, for dynamic property and the oilness of burning methanol fuel especially high-proportion methanol fuel vehicle provides solution.
