Description
Technical field
The present invention relates to a kind of engine oil composition and uses thereof.
Background technology
Lubricating oil in use, due to running up of parts, be subject to the reasons such as strong stirring or vibration, produce a large amount of bubbles, thereby cause the consequences such as oil lubrication degradation, cooling performance variation, the easier deterioration by oxidation of machine oil, affect the normal running of engine and work-ing life.Therefore the requirement of stricter anti-foam characteristic engine oil has been proposed.In addition,, along with popularizing of engine design miniaturization and motorway, the service temperature of engine is than improve in the past, machine oil is in higher use temperature, and at high temperature, parts are higher to the requirement of lubrication and cooling, thereby it is more responsive that lubricating oil is carried secretly to bubble-related issues.In high-grade vapour, diesel engine oil, all the high temperature antifoam property to oil product has proposed requirement at present.
The reason of lubricating oil foaming is a lot, and air and the minor amount of water of wherein in oil, dissolving may be the important factors that causes oil product at high temperature to foam.At high temperature, change bubble into and discharge after the moisture in lubricating oil is heated, the boiling point of water is 100 ℃, under the high temperature of 150 ℃, can fiercely seethe with excitement, and produces a large amount of water vapor bubbles, has directly increased oily foaminess.
In order to suppress oil product foaming, one of effective means is in oil product, to add kilfoam.Kilfoam is generally not dissolved in oil, but be present in oil with the colloidal particle state of high dispersing, the kilfoam particle disperseing is adsorbed on vacuolar membrane, then invade vacuolar membrane and become its part, then constantly expansion on vacuolar membrane, vacuolar membrane is thinned down, until film rupture, and reach brokenly bubble object.Kilfoam must be under insoluble state, just to have good anti-bubble effect.At high temperature, the solubility property of some kilfoams increases, thereby causes the anti-bubble deleterious of kilfoam, has even played opposite effect.
Document CN1282783A discloses a kind of engine oil composition, comprising sulfur phosphorization polyisobutylene titanate salt, alkyl monosulfide phenates, polyisobutene succinimide ashless dispersant, oxidation inhibitor, pour point depressant, kilfoam, mineral oil basis oil.But there is the not good enough problem of high temperature antifoam property in it.
Summary of the invention
One of technical problem to be solved by this invention is the not good enough problem of engine oil high temperature antifoam property in prior art, and a kind of new engine oil composition is provided.Two of technical problem to be solved by this invention is to provide a kind of purposes of the engine oil composition corresponding with one of technical solution problem.Use described engine oil composition, do not affecting under the prerequisite of other performances of lubricating oil, make engine oil there is good high temperature antifoam property.
For one of solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of engine oil composition, comprises following component in parts by weight:

2difference, n is positive integer.
In technique scheme, in parts by weight, the consumption preferable range of purification agent, dispersion agent or its mixture is 1 ~ 40 part, and more preferably scope is 10 ~ 40 parts; The consumption preferable range of silicone oil kilfoam is 1 ~ 20 part, and more preferably scope is 1 ~ 10 part; The consumption preferable range of base oil is 40 ~ 80 parts, and more preferably scope is 50 ~ 75 parts.Described purification agent preferred version is at least one being selected from sulfonate, calcium sulfenyl phenolate, magnesium alkylsalicylate, alkyl sodium salicylate or Acid Thiosalicylique calcium; Wherein, described sulfonate preferred version is at least one being selected from calcium mahogany sulfonate, calcium alkylbenzenesulfonate, super base number synthetic sulfonic acid magnesium, overbased petroleum magnesium sulfonate or expanded sulfonate; Wherein, described calcium mahogany sulfonate preferred version is at least one being selected from low alkali value calcium mahogany sulfonate, middle base number calcium mahogany sulfonate or high base number calcium mahogany sulfonate, and described calcium alkylbenzenesulfonate preferred version is at least one being selected from low alkali value calcium alkylbenzenesulfonate, middle base number calcium alkylbenzenesulfonate or high base number calcium alkylbenzenesulfonate.Described dispersion agent preferred version is at least one being selected from succimide dispersion agent or nitrogen borated dispersant; Wherein, described succimide dispersion agent is selected from least one in mono butonediimide, two succimide or many succimides.In the anti-bubble molecular formula of described silicone oil kilfoam silicone oil, n is less than 70 integer, and molecular weight preferable range is 1000 ~ 10000.
The preparation method of engine oil composition of the present invention is: each component is added in base oil in proportion at 50 ~ 60 ℃ of temperature, stir 0.5 ~ 1 hour, it is all dissolved, can obtain composition of the present invention.
For solve the problems of the technologies described above two, the technical solution used in the present invention is as follows: above-mentioned engine oil composition is for improving the high temperature antifoam property of engine oil.Identical in the technical scheme that the component of wherein said engine oil composition, weight percentage and preferable range are taked with one of technical solution problem.
Engine oil composition of the present invention can be used for gasoline and starts in oil and diesel engine oil.Its using method is as follows: the present composition with 0.01 ~ 1.0% (weight) dosage makes an addition in engine oil product, can effectively improve the at high temperature phenomenon of antifoam property variation of oil product, improve the high temperature lubrication property of engine oil, and in it and oil product there is not repulsive interaction in other additives, can not exert an influence to use propertieies such as the detergent-dispersant performance energy of oil product, antioxygen preservative property, obtain good technique effect.
