Abstract

The invention relates to a positive photoresist rubber composite of table tennis rackets. The composite is prepared from components of raw materials in parts by weight as follows: 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, 10-20 parts of hydroxyl acrylic resin, 5-10 parts of a vulcanization activator, 0.1-2 parts of a vulcanization accelerator, 0.1-1 part of sulfur and 0.1-2 parts of an anti-aging agent. According to the formula comprising natural rubber, 10-30 parts of trans-1,4-polyisoprene rubber, butadiene rubber, polyvinyl imidazole and other substances, the elasticity and hardness of the prepared rubber are well balanced, quick return speed, stable hitting, non-losing and other technical specialties of athletes are played.

Description

technical field [0001] The invention relates to a positive rubber rubber, in particular to a positive rubber composite material 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 ma...
