Description
Technical field
The present invention relates to a kind of positive photoresist rubber, and in particular to a kind of table tennis racket sponge.
Background technology
Table tennis bat positive photoresist rubber is also short particle rubber, should have higher resilience and hardness, be conducive to sportsman
Play that return of serve speed is fast, and batting is steady, do not eat and the technology speciality such as turn, be adapted to close-to-table fast attack, especially backhand block with forehand type play, be straight
One of most common rubber type of plate quick attack type player.It is general to select natural rubber and be used as base with elasticity preferably butadiene rubber
Body material.But the ratio of cis-butadiene cement is excessive, rubber hardness can be caused, strongly reduced with elongation, particle is easily destroyed, uses
The lost of life；Therefore, merely using natural rubber/butadiene rubber and be difficult meet high resiliency, high rigidity technical requirements, put down
Weighing apparatus high resiliency and high rigidity are the big difficult points in rubber composition design.
The content of the invention
A kind of table tennis racket sponge is provided the invention aims to overcome the deficiencies in the prior art.
To solve above technical problem, a kind of technical solution that the present invention takes is：A kind of table tennis racket sponge, it

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 and polyacrylonitrile pass through conventional radical polymerization by its corresponding monomer respectively
Conjunction obtains, its number-average molecular weight is independently of one another 10000~100000.
The present invention relates to a kind of preparation method of above-mentioned table tennis racket sponge, comprise the following steps：
(1) by the natural rubber, trans 1,4 polyisoprene rubber, polyvinyl imidazol, the polypropylene of formula ratio
Nitrile and Hydroxylated acrylic resin are blended on rubber mixing machine, then the vulcanizing activator and antioxidant of addition formula ratio, after cutter again
Vulcanization accelerator and Sulfur are added, 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：Table tennis bat of the present invention
Anti- glue rubber, by using natural rubber, anti-form-1, the material shape such as 4- polyisoprene rubbers 10~30, polyvinyl imidazol
Into formula, obtained rubber with good hardness, is conducive to sportsman and improves what is played ball while with excellent resilience
Rotary force, while it is steady to bat, is not easy to eat and turns etc..
