Abstract

The invention relates to a high elastic table tennis bat front rubber cover. The cover is prepared from, by weight, 50-80 parts of natural rubber, 10-30 parts of trans -1,4- polyisoprene rubber,10-40 parts of butadiene rubber, 10-30 parts of polyvinyl imidazole, 5-10 parts of polymethyl methacrylate, 10-20 parts of hydroxy acrylic resin, 5-10 parts of vulcanizing activators, 0.1-2 parts of vulcanizing accelerators, 0.1-1 part of sulphur and 0.1-2 parts of antiagers. Through the formula formed by substances of the natural rubber, the trans -1,4- polyisoprene rubber, the butadiene rubber, the polyvinyl imidazole and the like, the prepared rubber cover achieves a good balance between elasticity and rigidity, and helps the athletes to give play to technical specialties such as fast ball return speed, stable ball hitting and no ball losing.

Description

technical field [0001] The invention relates to a positive rubber, in particular to a high-elastic positive rubber for a table tennis racket. Background technique [0002] The normal rubber of table tennis rackets is also called short-grain rubber. It should have high resilience and hardness, which is conducive to athletes to play the technical advantages of fast return speed, stable hitting, and no spin. It is suitable for fast attack near the table, especially the left The push right attack style is one of the most commonly used rubber types for straight fast break players. Generally, natural rubber is used and butadiene rubber with better elasticity is used as the base material. However, if the proportion of butadiene rubber is too large, the hardness, strength and elongation of the rubber will be reduced, the particles will be easily damaged, and the service life will be shortened; Technical requirements, balancing high elasticity and high hardness is a major difficult...
