Abstract

The invention relates to a high-elasticity inverted rubber sheet composition for a table tennis bat. The high-elasticity inverted rubber sheet composition for the table tennis bat comprises the following raw components in parts by weight: 150 to 180 parts of natural rubber, 10 to 40 parts of cis-polybutadiene, 10 to 30 parts of polyvinyl imidazol, 5 to 10 parts of polymethyl methacrylate, 10 to 20 parts of hydroxy acrylic resin, 5 to 10 parts of a vulcanizing activator, 0.1 to 2 parts of a vulcanizing accelerator, 0.1 to 1 part of sulphur, and 0.1 to 2 parts of an anti-ageing agent. The elasticity and the hardness of the rubber sheet which is prepared by using the formula formed by the substances, such as the natural rubber, the trans-1,4-polyisoprene rubber, the cis-polybutadiene and the polyvinyl imidazol reach good balance, which are beneficial for an athlete to play the technical specialties of high ball returning speed, stable ball hitting, no rotating ball losing and the like.

Description

technical field [0001] The invention relates to a positive rubber, in particular to a high-elastic reverse rubber composition 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 majo...
