Abstract

The invention discloses a black table tennis racket inverted rubber composition with high viscosity and high elasticity. The composition comprises a matrix material composed of a blend of 50-100 parts by mass of a natural rubber and 0-50 parts by mass of a butadiene rubber, 1-3 parts by mass of an anti-aging agent, 1-10 parts by mass of a filler, 6-13 parts by mass of a vulcanizing activator, 1-5 parts by mass of a vulcanizing accelerator, 0.5-3.5 parts by mass of sulfur and 10-30 parts by mass of a tackifier. The composition is simple in preparation process and low in cost; the prepared table tennis racket inverted rubber has good rebound resilience and relatively high viscosity that can be kept for a long time, thereby guaranteeing fast tennis ball speed, high rotation ball-making efficiency and high control ability for the tennis balls; and at the same time, the rubber has smooth appearance without blooming phenomenon, so that the table tennis racket can be well balanced in both performance and appearance and be beneficial to athlete health.

Description

[0001] technical field [0002] The invention discloses a black anti-adhesive rubber composition for table tennis rackets with high viscosity and high elasticity. Fast return speed, strong rotation, easy to control the ball; at the same time ensure that the preparation process is simple, low cost, the surface of the rubber is smooth and flat, and there is no blooming phenomenon, so that the product has a good balance in performance and appearance, which is conducive to protecting athletes healthy. The invention relates to the technical field of manufacturing rubber products and sports equipment. technical background [0003] The anti-rubber rubber of table tennis rackets should have high resilience to ensure fast return speed. It is suitable for fast attack and fast loop ball. 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 strength and elongation of...
