[0002] A table tennis racket rubber with a concave particle structure is a table tennis racket rubber in which the top of each particle is concave. The rubber with this particle structure uses the concave structure and the elastic deformation of the elastic material to generate a negative pressure air chamber at the top of the particle during the process of hitting the table tennis ball, thereby increasing the positive pressure and friction when hitting the ball. The table tennis racket rubber is a rubber that is glued to the bottom plate of the table tennis racket and covered on the sponge. The performance and characteristics of the rubber will affect the rotation, speed, control and other aspects of the table tennis ball. At the same time, the rubber also needs to be maintained to extend the service life of the rubber.

[0003] In the prior art, most of the rubbers on the market are made of rubber. In summer, when the temperature of the indoor and outdoor environments is high, if the table tennis racket is not stored properly, the elasticity, friction and other properties of the rubber may be affected due to the high temperature, accelerating the aging process of the rubber and shortening its service life. Therefore, a table tennis racket rubber with a concave rubber particle structure is needed. Utility Model Content

DETAILED DESCRIPTION

[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0021] Reference Figure 1-6 The embodiment of the present invention is a table tennis racket rubber with a concave rubber particle structure, which includes a rubber 1. The upper surface of the rubber 1 is fixedly connected to a rubber particle 2. The rubber particle 2 is provided with a groove 3. The number of the rubber particles 2 is multiple and distributed in a rectangular array. The number of the grooves 3 is multiple and distributed in a rectangular array. The rubber 1 is a multi-layer composite structure. From top to bottom, a high-temperature resistant layer 4, a flexible layer 5 and a low-temperature resistant layer 6 are sequentially arranged. The high-temperature resistant layer 4 is a multi-layer composite structure. From top to bottom, a polyarylate layer 7, a polyimide layer 8 and a polyphenylene layer 9 are sequentially arranged. The flexible layer 5 is a multi-layer composite structure. From top to bottom, a styrene-butadiene rubber layer 10 is sequentially arranged. The low-temperature resistant layer 6 is a multi-layer composite structure with the butadiene rubber 11, and is provided with a polytetrafluoroethylene layer 12, a polyetheretherketone layer 13 and a polyphenylene sulfide layer 14 in sequence from top to bottom. The polyimide layer 8 covers the lower surface of the polyarylate layer 7, the polyphenylene layer 9 covers the lower surface of the polyimide layer 8, the styrene-butadiene rubber layer 10 covers the lower surface of the polyphenylene layer 9, the butadiene rubber 11 covers the lower surface of the styrene-butadiene rubber layer 10, the polytetrafluoroethylene layer 12 covers the lower surface of the butadiene rubber 11, the polyetheretherketone layer 13 covers the lower surface of the polytetrafluoroethylene layer 12, and the polyphenylene sulfide layer 14 covers the lower surface of the polyetheretherketone layer 13.

[0022] Working principle: The polyarylate layer 7, polyimide layer 8 and polyphenylene layer 9 provided on the high-temperature resistant layer 4 can improve the overall high-temperature resistance of the rubber 1, so that the rubber 1 will not accelerate the aging speed in the high-temperature environment in summer. At the same time, the styrene-butadiene rubber layer 10 and polybutylene rubber 11 provided on the flexible layer 5 can improve the overall flexibility of the rubber 1. When the rubber 1 is impacted by a table tennis ball, the impact force transferred to the racket when hitting the ball can be reduced, thereby reducing the impact transferred to the hand, making the hitting process more comfortable. In addition, the polytetrafluoroethylene layer 12, polyetheretherketone layer 13 and polyphenylene sulfide layer 14 provided on the low-temperature resistant layer 6 can improve the overall low-temperature resistance of the rubber 1, so that the rubber 1 will not accelerate the aging speed in the low-temperature environment in winter.

[0023] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
