Optimally, the antioxidant is 2,6-di-tert-butyl p-cresol or 2, and 2,4- trimethyl -1,2- dihyaroquinolines gather Compound.
Optimally, the number-average molecular weight of the Hydroxylated acrylic resin is 10000~100000.
Optimally, the polyvinyl imidazol, polyacrylonitrile and polymethyl methacrylate are respectively by its corresponding monomer Obtained by conventional radical polymerization, its number-average molecular weight is independently of one another 10000~100000.
The present invention relates to it is a kind of it is above-mentioned be used for make table tennis racket sponge polymer composite preparation method, Comprise the following steps：
(1) by the natural rubber of formula ratio, polyvinyl imidazol, thermoplastic elastomer (TPE), polyacrylonitrile, poly- methyl-prop E pioic acid methyl ester and Hydroxylated acrylic resin are blended on rubber mixing machine, then add the vulcanizing activator and antioxidant of formula ratio, cut Vulcanization accelerator and Sulfur are added after knife, after being kneaded uniformly, slice is stand-by；
(2) rubber compound obtained by step (1) is vulcanized by vulcanizing press, prepares the height that surface is smooth, smooth Hardness table tennis bat positive photoresist rubber.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：The present invention is used to make The polymer composite of table tennis racket sponge, is matched somebody with somebody by using what the materials such as natural rubber, polyvinyl imidazol were formed Side, obtained rubber elasticity and hardness reach well balanced, are conducive to sportsman and play that return of serve speed is fast, and batting is steady, do not eat and turn Etc. technology speciality.
