Background technology
Crude oil be by more than 95% carbon, hydrogen compound mix, remainder less than 5% be sulphur, chlorine, nitrogen and metallic element
The organic and inorganic miscellaneous element compound constituted, though the few technique and product for affecting whole oil plant of this kind compound content
Quality.As main refined oil product, increasingly serious with environmental pollution, people require in reduction fuel oil for vehicles one after another
The nuisance composition such as sulphur, nitrogen and aromatic hydrocarbons, to reduce the pollution that it is produced to air after combustion.European Union in 2005 and
Start within 2008 to perform European Union's motor vehicle emission stage iv standard (Europe IV) and European Union vehicular pollutant row respectively
Put V stage criterions (Europe V), respectively provided in two above-mentioned standards sulfur content in fuel oil not above 50ug/g and
10ug/g.China has formulated corresponding fuel emission regulation with reference to European standard of fuel, wherein national stage iv motor vehicle row
Put standard (state IV), national V stage vehicle emission standards (state V) respectively provide sulfur content in fuel oil not above
50ug/g and 10ug/g.In order to meet the requirement of these standards, it is necessary to which gasoline, diesel oil are refined, sulphur therein, nitrogen are removed
Element, but inevitably remove some in subtractive process and play wear-resistant nitrogen-containing compound, such as pyrroles, indoles, pyrrole
Pyridine and quinoline etc..These materials are respectively provided with preferable abrasion resistance, are removed the lubricity of rear fuel oil and will drastically decline.
Diesel engine oil supply system is in itself come the injection pump being lubricated, due to the decline of abrasion resistance by diesel oil
The injection pump of the diesel oil fuel feeding caused by abrasion can be caused not smooth, the normal work of Diesel engine is had a strong impact on.To ensure diesel oil
The normal operation of engine system, appropriate diesel antiwear additive technology is added in diesel oil and is adopted extensively in industry
With.
A large amount of reports on diesel antiwear additive are had in the prior art, for example：
Granted patent CN102965201 B, CN105001924 B and applied the disclosed A of CN 106350217,
Disclosed by CN105154148 A, CN 105154148 A etc. is the preparation method of ester type diesel antiwear additive, mainly will be sweet
Oil, aliphatic acid or unrighted acid etc., heat under the protection of inert gas or under different types of catalyst action and carry out
Esterification, obtains the ester type diesel antiwear additive of specific composition.
Granted patent CN1234825 C, CN100448960 C are disclosed using modified grease or modification biological diesel oil as raw material
Diesel antiwear additive preparation method.
Granted patent CN 101768480 B, CN 103952193 B respectively with different particular compositions prepare diesel oil resist
Grinding agent.
On the whole, diesel antiwear additive of the prior art, the effect of ester type component is single, compound addition solvent etc. its
It is restricted in terms of its compound and feature.
The content of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of one kind has wear resistence, antistatic behaviour and anti-corrosion
The compound ester type multi-effect diesel antiwear additive of property, the antiwear additive component not only wherein selected in metal surface high adsorption capacity,
Its abrasion-resistance is further enhanced, and with anticorrosive and antistatic property.Different from current existing compound bavin
Oily antiwear additive is required to add appropriate solvent, and has influence on the inherent application performance of product, the compound ester type multi-effect diesel oil
The preparation technology of antiwear additive is simple, one multi-purpose, comprehensive cost is low.
Another object of the present invention, which is also resided in, provides a kind of described compound ester type multi-effect diesel antiwear additive as diesel oil
The application of additive.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of compound ester type multi-effect diesel antiwear additive, it is characterised in that by percentage to the quality, including 90~96wt%
Olein, 2~8wt% cycloalkanes acid glyceride, 2~6wt%N, the sub- bigcatkin willow propane diamine (code name T1201) of N- bis-.
As the preferred scheme of the present invention, raw material proportioning is：90~95wt% oleins, 3~7wt% aphthenic acids are sweet
Grease, 2~4wt%N, the sub- bigcatkin willow propane diamine (code name T1201) of N- bis-.
The olein is selected from vegetable oil acid glyceride.
The cycloalkanes acid glyceride is selected from after hydrorefined naphthenic acid is esterified with glycerine through catalyst and refines gained.
The sub- bigcatkin willow propane diamine (code name T1201) of the N, N- bis- is selected from N, and the sub- salicylides of N- bis- are dehydrated with propane diamine through condensation
Gained is refined afterwards.
The preparation method of compound ester type multi-effect diesel antiwear additive of the present invention is：By 90~96wt% oleins, 2
~8wt% cycloalkanes acid glyceride, 2~6wt%N, the sub- bigcatkin willow propane diamine (code name T1201) of N- bis- are stirred under the conditions of certain temperature
It is well mixed, impurity is then filtered to remove, is produced.
The invention further relates to application of the described compound ester type multi-effect diesel antiwear additive as diesel fuel additives.
Compound ester type multi-effect diesel antiwear additive obtained by the present invention, is added directly into diesel oil blending system, in oil
Good dispersion, in addition to improving the abrasion resistance of diesel oil, while have improve plus agent after diesel oil electric conductivity and tarnish protection

Grinding agent, ester type antiwear additive, compound antiwear additive make performance comparison, the results are shown in Table 2.
Table 2 adds the diesel fuel applications performance comparison of various different diesel antiwear additives
It is wear-resistant for heterogeneity diesel oil addition embodiments of the invention 3 (code name NWX-3) and commercially available acid type from table 2
Agent, ester type antiwear additive, compound antiwear additive add the compound ester type multi-effect diesel antiwear additive of the present invention from the point of view of performance comparision
Afterwards, the more other compound antiwear additives of the wear resistence of diesel oil, electrical conductivity are with the obvious advantage, objectively responded compound ester type multi-effect diesel oil
The characteristics of one multiple-effect of antiwear additive.
In summary, compound ester type multi-effect diesel antiwear additive properties of product of the invention stabilization, oil-soluble are good, anticorrosive
Ability is strong, conductive capability is strong, wear resistence is good, simple to operate, auxiliary agent integrated cost reduction.
