Rhein Chemie Rheinau GmbH application patent CN1856527A, CN1840622A and
The viscosity temperature characteristic of the lubricant oil composite disclosed in CN1861673A is poor, gluing of this lubricant oil composite
Spend along with the reduction of temperature can be increased dramatically, and along with the rising of temperature can strongly reduce, but at low temperature
Lower viscosity is excessive or the at high temperature too small application the most not utilizing lubricant oil composite of viscosity, and this will be very
The application of this lubricant oil composite is limited in big degree.Therefore, need exploitation one badly and have the most viscous
The lubricant oil composite of warm nature energy.
Summary of the invention
The invention aims to the defect overcoming existing lubricant oil composite viscosity temperature characteristic poor, and
There is provided a kind of and there is the lubricant oil composite of excellent viscosity temperature characteristic, the preparation method of a kind of lubricant oil composite
And the lubricant oil composite prepared by the method.
The present inventor finds after further investigation, Rhein Chemie Rheinau GmbH's application
Above-mentioned several patents CN1856527A, CN1840622A and CN1861673A disclosed lubrication line of oils
Dispersion phase in compound is to use polyfunctional compound or peroxide to be obtained by chemical crosslinking mode
Micro gel, although the lubricant oil composite containing this microgel particle can reduce organic to a certain extent
The coefficient of friction of medium, but the viscosity of these lubricant oil composites is influenced by temperature relatively big, and temperature is too
High (viscosity is the least) or the lowest (viscosity is the biggest) all can limit the use of this lubricant oil composite, is suitable for
Temperature range is narrower.And the rubber particles with cross-linked structure prepared by cross-linking radiation method with pass through
Polyfunctional compound or peroxide is used to carry out the rubber grain with cross-linked structure of chemical crosslinking preparation
Son has diverse microstructure.When the dispersion phase in lubricant oil composite is by cross-linking radiation side
When prepared by method has the ethylene-vinyl acetate rubber particles of cross-linked structure, corresponding lubricating oil composition
Thing has good viscosity temperature characteristic, it is possible to very well regulates viscosity along with the change of temperature, reduces low
Temperature viscosity also improves high temperature viscosity, therefore, it can make up to a great extent owing to the change of temperature is to viscous
The impact that degree causes.Additionally, high-energy radiation the most very cleaning, safety and the efficient energy, mesh
Before be widely used for the fields such as health care, food processing, commercial production by a lot of developed countries, instead
But use Chemical Crosslinking Methods (peroxide) to there are some very important problems, such as production efficiency
The environmental pollution etc. that the highest, peroxide remains and may cause, these all can limit its application.Base
In this, complete the present invention.
Specifically, the invention provides a kind of lubricant oil composite, wherein, described lubricant oil composite contains
Have base oil and be dispersed in described base oil by prepared by cross-linking radiation method, there is cross-linked structure
Ethylene-vinyl acetate rubber particles, described base oil is continuous phase, described ethylene-vinyl acetate
Rubber particles is dispersion phase, and relative to the described base oil of 100 weight portions, described ethyl vinyl acetate second
The content of alkene ester rubber particles is 0.005-10 weight portion.
Present invention also offers the preparation method of a kind of lubricant oil composite, the method is by base oil and passes through
The ethylene-vinyl acetate rubber particles to be disperseed of cross-linked structure that prepared by cross-linking radiation method have is carried out
Mix and disperse, and relative to the described base oil of 100 weight portions, described in ethyl vinyl acetate second to be disperseed
The consumption of alkene ester rubber particles is 0.005-10 weight portion.
Present invention also offers the lubricant oil composite prepared by said method.
The lubricant oil composite that the present invention provides can regulate viscosity effectively along with the change of temperature, and contains
Have by chemical crosslinking ethylene-vinyl acetate rubber particles compare, its at low temperatures viscosity lower,
And at high temperature viscosity is higher, and its viscosity index (VI) is bigger, it is possible to meets temperature and reaches more than 200 DEG C
The use requirement of occasion, therefore, has significantly widened the use temperature range of this lubricant oil composite.This profit
Sliding oil composition can be used for other hot industry oil such as blends engine oil, gear oil, hydraulic oil, is suitable for
In regulation viscosity temperature characteristic poor with double ring arene, polycyclic aromatic hydrocarbon and non-hydrocarbons base oil as key component
The viscosity temperature characteristic of lubricating composition, can be according to the demand in different operating place, easy adjustment goes out to have
The lubricating oil of different viscosity temperature characteristics.
Owing to cross-linking radiation makes the special construction that rubber particles had, the lubricating oil composition that the present invention provides
The ageing-resistant performance of thing is excellent, and the most easy to change, the most this lubricant oil composite can be as excellent performance
Lubricating oil use, be especially applicable to the viscosity temperature characteristic to lubricating oil system, ageing properties and frictional property
Higher field can be required, such as engine oil.
Additionally, ethylene-vinyl acetate powdered rubber particle prepared by cross-linking radiation method is because cross-linking more
Adding uniformly, particle diameter distribution is narrower, is easier to reach nanoscale dispersed in base oil, even if when it
Also can good dispersion during proportion higher (5 weight %) in lubricant oil composite.And cross-linked by employing
Agent (polyfunctional compound or peroxide) is limited to cross-linking agent in rubber latex when being chemically crosslinked
Dissolve and diffusivity, be extremely difficult to the most uniform crosslinking degree, cause the rubber particle size of crosslinking
There is larger difference, so it disperses more difficulty in base oil, such as, when it is at lubricating oil composition
When in thing, proportion reaches 3 weight %, easily there is the lamination of part in the lubricant oil composite of preparation,
This is the performance of bigger rubber particles sedimentation, and result makes lubricant compositions viscosity temperature characteristic decline.Additionally,
When continuing to increase chemical crosslinking ethylene-vinyl acetate rubber particles proportion to 5 weight %, the lubrication of preparation
Fluid composition then cannot carry out dispersed by present invention process, and reason is uneven crosslinking and bigger chi
Very little rubber particles is very easy to blocking and damage equipment.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
