There are the mechanical performance of the plastics of this micro gel, swelling behavior, stress corrosion cracking performance etc..But,
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 rubber particles of cross-linked structure, corresponding lubricant oil composite has good viscous temperature
Performance, 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.This
Outward, high-energy radiation the most very cleaning, safety and the efficient energy, the most by a lot of flourishing states
Family is widely used for the fields such as health care, food processing, commercial production, is to use chemical crosslinking on the contrary
There are some very important problems in method (peroxide), as the highest in production efficiency, peroxide is residual
The environmental pollution etc. stayed and may cause, these all can limit its application.Based on this, complete this
Bright.
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
Rubber particles, described base oil is continuous phase, and described rubber particles is dispersion phase, and relative to 100
The described base oil of weight portion, the content of described rubber particles is 0.001-10 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
Cross-linked structure that prepared by cross-linking radiation method have treat that disperse rubber particles mixes and disperses, and phase
For the described base oil of 100 weight portions, described in treat that the consumption of disperse rubber particles is 0.001-10 weight
Part.
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 the lubricant oil composite of rubber particles by chemical crosslinking to 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 200 DEG C to enter the court
The use requirement closed, therefore, has significantly widened the use temperature range of this lubricant oil composite.This lubrication
Fluid composition can be used for other hot industry oil such as blends engine oil, gear oil, hydraulic oil, it is adaptable to
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, and easy adjustment goes out to have not
Lubricating oil with 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, rubber particles prepared by cross-linking radiation method is because crosslinking is more uniform, particle diameter distribution is narrower,
In base oil, it is easier to reach nanoscale dispersed, even if proportion is relatively in lubricant oil composite when it
Also can good dispersion time high (5 weight %).And by using cross-linking agent (polyfunctional compound or peroxide
Compound) it is limited to cross-linking agent when being chemically crosslinked and dissolves and diffusivity in rubber latex, it is difficult to reach
To completely uniform crosslinking degree, cause the rubber particle size of crosslinking to there is larger difference, thus its
Base oil disperses more difficulty, such as, when in lubricant oil composite, proportion reaches 3 weight % for it,
Easily there is the lamination of part in the lubricant oil composite of preparation, and this is the table of bigger rubber particles sedimentation
Existing, result makes lubricant compositions viscosity temperature characteristic decline.Additionally, continue to increase chemical crosslinking rubber grain
When sub-proportion is to 5 weight %, the lubricant oil composite of preparation then cannot be carried out uniformly by present invention process
Dispersion, reason is that the rubber particles of uneven crosslinking and large-size 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.
