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 nitrile rubber particle of cross-linked structure, corresponding lubricant oil composite has good
Viscosity temperature characteristic, it is possible to very well regulate viscosity along with the change of temperature, reduces low temperature viscosity and improves
High temperature viscosity, therefore, it can make up the impact caused viscosity due to the change of temperature to a great extent.
Additionally, high-energy radiation the most very cleaning, safety and the efficient energy, the most by a lot of flourishing
Country is widely used for the fields such as health care, food processing, commercial production, is to use chemistry to hand on the contrary
There is some very important problems, as the highest in production efficiency, peroxide in linked method (peroxide)
Residual and the environmental pollution etc. that may cause, these all can limit its application.Based on this, complete this
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
Nitrile rubber particle, described base oil is continuous phase, and described nitrile rubber particle is dispersion phase, and phase
For the described base oil of 100 weight portions, the content of described nitrile rubber particle 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 nitrile rubber particle to be disperseed of cross-linked structure that prepared by cross-linking radiation method have mixes and disperses,
And relative to the described base oil of 100 weight portions, described in the consumption of nitrile rubber particle to be disperseed be
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
Having the lubricant oil composite of nitrile rubber particle by chemical crosslinking to compare, viscosity is more at low temperatures for it
Low, and at high temperature viscosity is higher, and its viscosity index (VI) is bigger, it is possible to and meet temperature and reach 200 DEG C
The use requirement of above occasion, therefore, has significantly widened the use temperature range of this lubricant oil composite.
This lubricant oil composite can be used for other hot industry oil such as blends engine oil, gear oil, hydraulic oil,
Be applicable to regulate viscosity temperature characteristic poor with double ring arene, polycyclic aromatic hydrocarbon and non-hydrocarbons base oil be main
The viscosity temperature characteristic of the lubricating composition of component, can go out according to the demand in different operating place, easy adjustment
There is the lubricating oil of different viscosity temperature characteristic.
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, powder nbr rubber particles prepared by cross-linking radiation method is because crosslinking is more uniform, particle diameter
It is distributed narrower, in base oil, is easier to reach nanoscale dispersed, even if when it is at lubricating oil composition
Also can good dispersion during proportion higher (5 weight %) in thing.And by using cross-linking agent (multiple functionalized
Compound or peroxide) it is limited to cross-linking agent when being chemically crosslinked and dissolves and diffusion energy in rubber latex
Power, is extremely difficult to the most uniform crosslinking degree, causes the rubber particle size of crosslinking to there is larger difference,
So it disperses more difficulty in base oil, such as, when its proportion in lubricant oil composite reaches 3
During weight %, easily there is the lamination of part in the lubricant oil composite of preparation, and this is bigger rubber grain
The performance of son sedimentation, result makes lubricant compositions viscosity temperature characteristic decline.Additionally, continue to increase chemistry
When crosslinking acrylonitrile butadiene particle proportion is to 5 weight %, the lubricant oil composite of preparation then cannot pass through this
Bright technique carries out dispersed, and reason is that the rubber particles of uneven crosslinking and large-size is very easy to stifled
Plug and damage equipment.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
