Object.
In addition, there are also the answering in lubricating oil field about organic fine particles gel other than inorganic nano-particle
Report.For example, Rhein Chemie Rheinau GmbH application patent CN1856527A, CN1840622A and
CN1861673A discloses the micro gel of a kind of micro gel in non-crosslinkable organic media and crosslinking for changing
The purposes of the temperature-independent performance of the non-crosslinked organic media of property.However, this several patents application is pointed out bar none, institute
State micro gel and be by the way of chemical crosslinking (for example, by with polyfunctional compound's crosslinking copolymerization or pass through peroxide
Compound crosslinking) micro gel that is prepared, rather than the micro gel being crosslinked with high-energy radiation.Above-mentioned patent application thinks high
The micro gel of energy crosslinking with radiation is actually unable in be prepared on an industrial scale, and the use of the high-energy radiation of radioactivity cobalt source is with tight
The safety problem of weight, the and when micro gel of crosslinking with radiation is used in plastic matrix, can be between matrix and dispersed phase
Tearing effect occurs, to compromise the mechanical performance of the plastics containing the micro gel, swelling behavior, stress corrosion cracking
Energy is equal.However, in patent CN1856527A, CN1840622A and CN1861673A of Rhein Chemie Rheinau GmbH's application
The viscosity temperature characteristic of disclosed lubricant oil composite is poor, and the viscosity of the lubricant oil composite can sharply increase with the reduction of temperature
Greatly, it can strongly reduce as the temperature rises, but viscosity is excessive at low temperature or viscosity is too small unfavorable at high temperature
With the application of lubricant oil composite, this will greatly limit the application of the lubricant oil composite.Therefore, it needs to develop
A kind of lubricant oil composite with preferable viscosity temperature characteristic.
Summary of the invention
The defect that the purpose of the invention is to overcome existing lubricant oil composite viscosity temperature characteristic poor, and one kind is provided
It the preparation method of lubricant oil composite, a kind of lubricant oil composite with excellent viscosity temperature characteristic and is prepared by this method
Lubricant oil composite.
The present inventor has found that Rhein Chemie Rheinau GmbH applies several above-mentioned after further investigation
Dispersed phase in lubricant oil composite disclosed in patent CN1856527A, CN1840622A and CN1861673A is using multifunctional
The micro gel that compound or peroxide are obtained by chemical crosslinking mode, although the lubricating oil composition containing the microgel particle
Object can reduce the coefficient of friction of organic media to a certain extent, but the viscosity of these lubricant oil composites is by the shadow of temperature
Sound is larger, and temperature too high (viscosity is too small) or too low (viscosity is too big) will limit the use of the lubricant oil composite, applicable for temperature
It is relatively narrow to spend range.And the rubber particles with cross-linked structure that are prepared by cross-linking radiation method and by using multifunctional chemical combination
The rubber particles with cross-linked structure that object or peroxide carry out chemical crosslinking preparation have entirely different microstructure.When
It is corresponding when dispersed phase in lubricant oil composite is the rubber particles with cross-linked structure prepared by cross-linking radiation method
Lubricant oil composite have good viscosity temperature characteristic, very well can adjust viscosity with the variation of temperature, reduce it is low
Warm viscosity simultaneously improves high temperature viscosity, therefore, can largely make up variation influence caused by viscosity as temperature.
In addition, high-energy radiation actually very cleaning, the safe and efficient energy, is widely used for by many developed countries at present
The fields such as health care, food processing, industrial production, instead be using Chemical Crosslinking Methods (peroxide) there are it is some can not
The problem of ignorance, such as the environmental pollution that production efficiency is not high, peroxide is remained and be may cause, these can all limit it
Using.Based on this, the present invention is completed.
Specifically, the present invention provides a kind of lubricant oil composites, wherein the lubricant oil composite contain base oil and
The rubber particles with cross-linked structure prepared by cross-linking radiation method being dispersed in the base oil, the base oil
For continuous phase, the rubber particles are dispersed phase, and the base oil relative to 100 parts by weight, the rubber particles
Content be 0.005-10 parts by weight.
The present invention also provides a kind of preparation method of lubricant oil composite, this method is by base oil and passes through cross-linking radiation
The rubber particles to be dispersed with cross-linked structure of method preparation are mixed and are dispersed, and the institute relative to 100 parts by weight
Base oil is stated, the dosage of the rubber particles to be dispersed is 0.005-10 parts by weight.
The present invention also provides lubricant oil composites prepared by the above method.
Lubricant oil composite provided by the invention can effectively adjust viscosity with the variation of temperature, with contain passing through
The lubricant oil composite for learning the rubber particles of crosslinking is compared, and viscosity is lower at low temperature, and viscosity is higher at high temperature, and
And its viscosity index (VI) is larger, can satisfy the requirement that temperature reaches 200 DEG C or more occasions, therefore, has significantly widened the profit
The use temperature range of sliding oil composition.The lubricant oil composite can be used for blends engine oil, gear oil, hydraulic oil etc. other
Hot industry oil, with double ring arene, polycyclic aromatic hydrocarbon and non-hydrocarbons base oil is main suitable for it is poor to adjust viscosity temperature characteristic
The viscosity temperature characteristic of the lubricating composition of component can provide different viscous temperature according to the demand in different operating place, easy adjustment
The lubricating oil of performance.
Since cross-linking radiation makes special construction possessed by rubber particles, lubricant oil composite provided by the invention it is resistance to old
Change is had excellent performance, not easy to change, therefore this lubricant oil composite can be used as the lubricating oil haveing excellent performance and use, and especially answer
For the field more demanding to the viscosity temperature characteristic, ageing properties and frictional behaviour that lubricate oil systems, such as engine oil.
In addition, the rubber particles of cross-linking radiation method preparation are because crosslinking is more uniform, particle diameter distribution is narrower, on basis
It is evenly dispersed to be easier to reach nanoscale in oil, even if working as higher (the 5 weight %) Shi Yeneng of its specific gravity in lubricant oil composite
It is well dispersed.And crosslinking agent is limited to when being chemically crosslinked by using crosslinking agent (polyfunctional compound or peroxide) and is existed
Dissolution and diffusivity, are extremely difficult to the crosslinking degree of substantially uniformity in rubber latex, and the rubber particle size of crosslinking is caused to deposit
In larger difference, so it disperses more difficulty in base oil, for example, when its specific gravity in lubricant oil composite reaches 3 weights
When measuring %, the lubricant oil composite of preparation is easy to appear the lamination of part, this is the performance of larger rubber particles sedimentation, knot
Fruit declines lubricant compositions viscosity temperature characteristic.In addition, continuing growing chemical crosslinking rubber particles specific gravity to 5 weight %
When, the lubricant oil composite of preparation then can not through the invention technique carry out it is evenly dispersed, the reason is that uneven crosslinking and larger
The rubber particles of size are very easy to blocking and damage equipment.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
