Problems solved by technology

Regular table tennis players put on the rubber before the start of the game, which can ensure a good hitting and returning effect of the table tennis racket; however, amateur table tennis players cannot meet this condition, so choosing a rubber that can guarantee the hitting and returning effect for a long time is the best choice. It is particularly important, but the existing rubber is difficult to meet this requirement, and the table tennis racket or rubber that can reach this requirement is more expensive, and is not suitable for amateur table tennis players.

Embodiment 1

[0031] Such as figure 1 Shown is a schematic diagram of the mechanism of the present invention. The present invention is a table tennis racket rubber that is stable in hitting and returning the ball.

[0032] The surface bonding layer includes a fiber layer 3, a closed-cell foam 4 and an open-cell foam 5; the surface of the fiber layer 3 is evenly provided with a concave support groove 6 downward, and the vertical section of the support groove 6 is an inverted isosceles trapezoid , the width of the bottom of the support groove 6 is smaller than the width of the top of the support groove 6; the open-cell foam 5 is evenly and continuously attached to the bottom of the support groove 6; the closed-cell foam 4 is evenly and continuously attached to the lower surface of the fiber layer 3, and is located adjacent to Between the two supporting grooves 6 , the elastic modulus of the closed-cell foam 4 is smaller than that of the open-cell foam 5 , and the vertical sections of the open...

Embodiment 2

[0037] Compared with Example 1, Example 2 maintains the same rubber structure, and only changes the composition ratio of the upper fiber layer 9 and the lower fiber layer 11, specifically, spandex: 11 parts, butadiene rubber: 5 parts , Tackifier: 2 parts.

Embodiment 3

[0039] Compared with Example 1, Example 2 maintains the same rubber structure, and only changes the composition ratio of the upper fiber layer 9 and the lower fiber layer 11, specifically, spandex: 7 parts, butadiene rubber: 8 parts , Tackifier: 1 part.

[0040]The table tennis racket rubbers obtained according to the above three embodiments are respectively tested for hitting the ball, and the elastic effect of embodiment 1 and the time to maintain the hitting effect are optimal; embodiment 2 is slightly worse than embodiment 1 on the elastic effect, and The time for maintaining the batting effect is almost the same as that of Example 1; and Example 3 is slightly worse than Example 1 on both indicators, but is also significantly better than the existing table tennis bat rubber.

Abstract

The invention provides table tennis bat rubber achieving stable ball hitting and returning. The table tennis bat rubber sequentially comprises a bat blade coating, a flexible middle layer and a ball hitting surface layer; the bat blade coating comprises a fiber layer, closed cell foam and open cell foam; concave supporting grooves are downwards and uniformly formed in the surface of the fiber layer, and the width of the bottom of each supporting groove is smaller than that of the top of each supporting groove; the open cell foam is uniformly and continuously attached to the lower portions of the supporting grooves; the closed cell foam is uniformly and continuously attached to the lower surface of the fiber layer and located between every two adjacent supporting grooves, and the elasticity modulus of the closed cell foam is smaller than that of the open cell foam; ball hitting deformation protrusions are uniformly arranged on the top face of the flexible middle layer, and the bottom of the flexible middle layer is uniformly provided with colloidal particles; the vertical cross section of each ball hitting deformation protrusion is shaped like an arc; the colloidal particles are shaped like columns, and the width of the bottom end is smaller than that of the top of each supporting groove; the ball hitting surface layer is ball hitting rubber. According to the table tennis bat rubber achieving stable ball hitting and returning, by means of the creative layered structure, on the premise that the rubber elasticity is not reduced and the service life is not shortened, the stability of ball hitting and returning is guaranteed, and the hitting capacity of the rubber is improved.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a table tennis racket rubber with stable hitting and returning. Background technique [0002] Table tennis is our country's national sport, and it is very popular in our country. No matter where you can see table tennis venues and table tennis fans. Regular table tennis players put on the rubber before the start of the game, which can ensure a good hitting and returning effect of the table tennis racket; however, amateur table tennis players cannot meet this condition, so choosing a rubber that can guarantee the hitting and returning effect for a long time is the best choice. Appear to be particularly important, but existing rubber is difficult to reach this requirement, and the table tennis bat or rubber price that can reach this requirement is more expensive again, is not suitable for amateur table tennis players. [0003] Therefore, developing a kind of rubber that...
