The poly-alpha-olefin is prepared by polymerizing methyl trifluoro-propyl 2-allyl silane and alpha olefin under an anhydrous AlCl3 catalysis condition. The poly-alpha-olefin has high viscosity and viscosity index under conditions of high temperature and lower temperature and can be used as base oil of lubricant.
Description
Technical field
The present invention relates to a kind of siliceous fluorine-containing polyalphaolefin and preparation method thereof.
Background technology
Polyalphaolefin (PAO) is a kind of lubricating oil commonly used, is widely used in all kinds of friction means.It has the use temperature wide ranges, and pour point is low, the viscosity index height, and vaporization losses is little, the high-temperature thermal oxidation good security, advantage such as coking is few, and is nontoxic has shear stability in addition, unreactiveness, electrical property is good, can be used as damping fluid, hydraulic efficiency oil and lubricant etc. that wide temperature range uses.Because its these premium propertiess, its use face is very wide, has also obtained to use widely in space flight and aviation industry.The PAO ucon oil is mainly used in engine, removes in addition, also obtains considerable development and application in industrial gear oil, turning oil, automatic transmission fluid, hydraulic efficiency oil, grease base oil, thermal oil and technology wet goods field.
Generally speaking, fluorinated organic compound all has good lubricating property, therefore if pass through chemical synthesis process, the organic group that will contain active element F is incorporated in the PAO molecular structure, then can improve the lubricity of PAO on the one hand, resulting fluorine-containing PAO also has the excellent properties of PAO oil itself simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of siliceous fluorine-containing polyalphaolefin and preparation method thereof.
In the present invention, in synthetic PAO process, introduce molecular flexibility methyl trifluoro propyl silane molecule preferably, on the one hand F is introduced in the PAO molecular structure, simultaneously, because the silane molecule structure has relative good low-temperature flowing property, is introduced into, and helps to improve the viscosity temperature characteristic of PAO.
A kind of siliceous fluorine-containing polyalphaolefin is characterized in that: molecular structure represents that with formula (I) it is connected with two polyalphaolefin structures at the methyl trifluoro propyl silane two ends, and alhpa olefin is that carbon number is alhpa olefin or its composition of 6-16; Abbreviate FSiPAO as,
In the formula (I): m is the siliceous fluorine-based polyalphaolefin chain link quantity that contains, and equals 1-10.
The synthetic of fluorine-containing polyalphaolefin of the present invention can be represented with following chemical equation:
Involved in the present invention to raw material make by the organometallic chemistry reaction by methyl trifluoro propyl dichlorosilane and bromopropylene for the methyl trifluoro propyl diallylsilane, employed alhpa olefin is that carbon number is alhpa olefin or its composition of 6-16.
The synthetic method of compound may further comprise the steps:
A, polyreaction: the methyl trifluoro propyl diallylsilane reacted than 1: 4 according to metering with alhpa olefin, added anhydrous AlCl
3Catalyzed polymerization, temperature of reaction are 100～150 ℃, and the reaction times is 2-6 hour, and reaction finishes back adding aqueous sodium hydroxide washes and washs away catalyzer, promptly obtains primary product;
The aftertreatment of B, siliceous fluorine-containing polyalphaolefin: will add Na in the prepared siliceous fluorine-containing polyalphaolefin
2SO
4Solution washing is to pH neutrality, and dry back is removed and desolvated, and underpressure distillation to 200-250 ℃ of steaming removes lighting end wherein, and residuum is required product.
By above technical scheme, the synthetic compound has very high viscosity and viscosity index under high/low temperature condition, and the base oil that can be used as lubricating oil uses.
