Technical field
The present invention relates to a kind of silicone rubber and preparation method thereof, more particularly to a kind of base cage modle of trisiloxanes containing diphenyl Silicone rubber of silsesquioxane and preparation method thereof.
Background technology
Methyl phenyl vinyl silicone rubber refers to that a part of silicon atom on main chain is connected with dimethyl and another part is connected with One methyl and a phenyl, its special chemical constitution give a series of its excellent properties, are widely used to LED package materials The every field such as material, high-temperaure coating, heat-conducting glue, electronic apparatus, industry light industry textile industry, building materials.With the continuous of its application Expand, traditional phenyl silicone oil cannot meet day by day harsh use requirement.Therefore in the urgent need to developing one Plant the high silicone rubber of high temperature resistant, shear strength.
Content of the invention
It is an object of the invention to provide a kind of silicone rubber of the base of trisiloxanes containing diphenyl cage-type silsesquioxane and its Preparation method, the present invention have obtained a kind of high property by adding novel crosslinker diphenyl trisiloxanes base cage-type silsesquioxane Can phenyl siloxane rubber.The present invention is made by the use of the POSS structures simultaneously containing si-h bond with phenyl ring as the cross-linking agent of phenyl silica gel With successfully improve the combination property of phenyl siloxane rubber.
The purpose of the present invention is achieved through the following technical solutions：
A kind of silicone rubber of the base of trisiloxanes containing diphenyl cage-type silsesquioxane, the silicone rubber by following components by weight Meter composition：
100 parts of methyl phenyl vinyl silicone oil；
The hydrogeneous cross-linking agent 10-80 parts of phenyl；
1 ~ 20 part of metal-oxide；
0.1～5 part of catalyst.
The silicone rubber of the described base cage-type silsesquioxane of trisiloxanes containing diphenyl, the methyl phenyl vinyl silicon Oil, viscosity are 15000 mPa s ~ 50000 mPa s, and phenyl mass fraction is 5% ~ 55%, and vinyl mass fraction is 0.1% ~5%.
The silicone rubber of the described base cage-type silsesquioxane of trisiloxanes containing diphenyl, the hydrogeneous cross-linking agent structure of phenyl are as follows Shown：
.
The silicone rubber of the described base cage-type silsesquioxane of trisiloxanes containing diphenyl, the metal-oxide are oxidation Ferrum, stannum oxide, titanium oxide, zinc oxide, one or more in cerium oxide, granularity are 20nm ~ 30um.
The silicone rubber of the described base cage-type silsesquioxane of trisiloxanes containing diphenyl, the catalyst are Karstedt platinum Au catalyst, content are 3000 ~ 5000ppm.
The silicone rubber of the described base cage-type silsesquioxane of trisiloxanes containing diphenyl, above-mentioned all experimental drugs are passed through Dehydration technology process, is put into molecular sieve preservation afterwards.
The silicone rubber preparation method of the base cage-type silsesquioxane of trisiloxanes containing diphenyl, the hydrogeneous cross-linking agent synthesis side of phenyl Method is as follows：
（1）In the presence of chloroplatinic acid, 69mL diphenyl trisiloxanes and 10mL vinyltrimethoxy silanes are carried out Hydrosilylation, after the completion of reaction, low pressure removes unreacted diphenyl trisiloxanes (repeatable utilization) and by-product：
（2）Step one products therefrom and acetone, volume of toluene are compared 1:3 mixed solutions are added in there-necked flask；And at 50 DEG C Stir 10 minutes in thermostat water bath, be allowed to mix homogeneously, be then slowly added dropwise the hydrochloric acid of 3mol/L concentration, continue stirring, make Polymerization 60h, after waiting reaction to terminate, sucking filtration is carried out to which, crude product is obtained, by product washes of absolute alcohol three times, and Dried under conditions of 60 DEG C, then recrystallization is carried out with dichloromethane, tetrahydrofuran, toluene, the product obtained after recrystallization Thing is put in vacuum drying oven, and is dried under conditions of 60 DEG C, obtains diphenyl trisiloxanes base cage model sesquialter silica Alkane silicone rubber crosslinking agent；
.
Advantages of the present invention with effect is：
The present invention has obtained a kind of high-performance benzene by adding novel crosslinker diphenyl trisiloxanes base cage-type silsesquioxane Base silicone rubber.At present conventional methyl phenyl vinyl silicone rubber cross-linking agent is phenyl hydrogen-containing silicon oil, mostly straight chain type structure, Gu After change, gained colloid mechanical property is relatively low.Compared with the cross-linking agent of traditional phenyl siloxane rubber class product, diphenyl trisiloxanes base Cage-type silsesquioxane organosilicon cross-linking agent is higher as the silicone rubber kinds product introduced after can causing to be crosslinked of POSS structures has Thermostability and mechanical property；And POSS- cage-type silsesquioxane space networks more popular at present, study its conduct Make its development hindered as the compatibility is low during the cross-linking agent of the High performance silica gel containing phenyl.The present invention is utilized and is contained simultaneously Si-h bond is used as the cross-linking agent of phenyl silica gel with the POSS structures of phenyl ring, successfully improves the comprehensive of phenyl siloxane rubber Energy.
The present invention introduces the molecule containing phenyl ring and si-h bond in POSS structures so as to used as methyl phenyl vinyl silicon The cross-linking agent of rubber.The silicone rubber of the base cage-type silsesquioxane of trisiloxanes containing diphenyl and traditional phenyl siloxane rubber class product Compare, with higher thermostability and mechanical property, addition heat resistance accessory thermal decomposition temperature is more than 400 DEG C.
