Abstract

The invention relates to an antiwear additive for lubricating oil. The addition amount of the additive in lubricating oil is 3 wt% to 1wt one tenth of one percent. The general chemical formula of the additive is as shown in the specification, wherein R1, R2 and R3 are H or an alkyl group with 1-18 carbon atoms or a functional group substituted hetero atom containing alkyl group with 1-40 carbon atoms; and R1, R2 and R3 can be the same or can be different.

Description

A kind of additive for wear resistance of lubricating oil
(1) technical field
The present invention relates to a kind of additive for wear resistance of lubricating oil.
(2) background technology
The abrasion resistance of lubricating oil is the key point of lubricating oil research always.Zinc dialkyl dithiophosphate (ZDDP) is widely used in the various lubricating oil as wear-resistant, antioxygen, anti-corrosion multifunctional additive.But in recent years, ashless lubricating oil was owing to had good thermal oxidation stability, hydrolysis stability, resistance to emulsion, anti-bubble property, filterableness, air release property, stability in storage, and with the consistency of various lubricating oil, use more and more widely.Zinc dialkyl dithiophosphate (ZDDP) is owing to contain metal, and the application in no putty oil is restricted.Seeking the alternative ZDDP of a kind of ashless wear preventive additive and be applied in the lubricating oil, solve the wear-resistant problem of ashless lubricating oil, is the focus that present lubricating oil investigator pays close attention to.
The chemical general formula of known compound is following:
Figure BDA0000059629070000011
In the formula, R 1, R 2, R 3The substituted alkyl that contains a heteroatomic 1-40 carbon atom of alkyl or functional group for H or 1-18 carbon atom; R 1, R 2, R 3Can be identical, also can be inequality.
Chemical general formula of this compound (1) and preparation method have many-sided reported in literature, are applied in the ashless lubricating oil but never report the alternative zinc dialkyl dithiophosphate (ZDDP) of this compound, solve the wear-resistant problem of ashless lubricating oil.
(3) summary of the invention
The object of the present invention is to provide a kind of new purposes of the compound of chemical general formula (1), substitute zinc dialkyl dithiophosphate (ZDDP) fully and be used for ashless lubricating oil, solve the wear-resistant problem of ashless lubricating oil, is a kind of ashless wear preventive additive of excellent performance.
The compound of chemical general formula (1) is 3 percent (weight) to per milles (weight) of lubricating oil total amount as the add-on of additive in lubricating oil, and preferable add-on is 2 percent (weight) to per milles (weight).
In order to guarantee that general formula (1) compound can dissolve R well in lubricating oil 1, R 2, R 3In the summation of carbon atom with 12-54 for well, wherein most preferred is a di-n-butyl thiophosphatephosphorothioate amino dodecane salt, molecular formula is:
Figure BDA0000059629070000021
Next is:
Di-n-butyl thiophosphatephosphorothioate stearylamine salt; Di-n-octyl thiophosphatephosphorothioate octylamine salt; Di-n-octyl thiophosphatephosphorothioate amino dodecane salt; Di-n-octyl thiophosphatephosphorothioate stearylamine salt.Molecular formula is respectively:
Figure BDA0000059629070000022
Figure BDA0000059629070000031
The compound of chemical general formula (1) can obviously improve the abrasion resistance of lubricating oil as oil dope, substitutes zinc dialkyl dithiophosphate (ZDDP) fully and is used for ashless gear oil, hydraulicefficiency oil and ATF automatic transmission fluid.
(4) embodiment
Below in conjunction with embodiment, the present invention is specified.
