At the time of rubber change, the data showed that the solvent of the adhesive volatilized, which had a health problem for players.

じることから、このラバー粘着両面シートの使用は、選
手に嫌われ、普及されていないのが現状である。However, when rubber is adhered to the surface of a racket using a currently known table tennis rubber double-sided pressure-sensitive adhesive sheet, it is difficult to remove the rubber when trying to replace the rubber again. It takes time and effort to switch back. In addition, since the use of such an adhesive sheet causes disadvantages such as the repulsion force of the hit ball being obviously reduced, the use of this rubber adhesive double-sided sheet is disliked by athletes and is currently not widely used. .

いう結果を生じるものである。That is, the conventional table tennis rubber double-sided pressure-sensitive adhesive sheet reduces the repulsion of a hit ball because the base material is a film such as polyester or polypropylene, and the pressure-sensitive adhesive applied to the front and back surfaces of the base material is Since the solvent is volatilized by infusing unvulcanized rubber or synthetic resin, etc., neither the base material nor the adhesive has almost no elasticity. However, the impact causes plastic deformation of the pressure-sensitive adhesive sheet, resulting in a reduction in hitting speed.

ある。SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the double-sided pressure-sensitive adhesive sheet. A vulcanized rubber having high rebound resilience (for example, butadiene rubber) is used as a base material of the double-sided pressure-sensitive adhesive sheet. The present invention provides a rubber adhesive sheet for table tennis that can improve the hit ball repulsion force reducing action, which is a drawback of the conventional double-sided pressure-sensitive adhesive sheet, and can obtain an effective repulsion force at the time of hitting by using a film formed from It is in.

望ましい。Reference numeral 3 denotes a double-sided pressure-sensitive adhesive sheet used to adhere the table tennis racket body 1 and the table tennis rubber 2 to each other. The double-sided pressure-sensitive adhesive sheet 3 uses, for example, butadiene rubber having an elastic coefficient of 85 to 90. Sheet base material 3A
And a first adhesive layer 3B applied to one entire surface of the sheet substrate 3A, and a second adhesive layer 3C applied to the entire opposite surface. The first pressure-sensitive adhesive layer 3B and the second pressure-sensitive adhesive layer 3C are obtained by dissolving unvulcanized rubber or acrylic resin with a solvent such as toluene, normal hexane, or xylene. The thickness of the first and second pressure-sensitive adhesive layers is desirably 0.01 to 0.02 mm.

される。In other words, since the table tennis rubber 2 and the table tennis racket main body are made of different materials, in order to effectively adhere these different materials, an adhesive which is adhered to the rubber side and the wood side is used. It is desirable to appropriately select the adhesive strength (material). In particular, when a sheet that needs to be replaced frequently, such as the table tennis rubber 2, is adhered, it is desirable that the double-sided adhesive sheet can be intentionally relatively easily peeled off from the table tennis racket body. Adhesive layer 3
It is required to change the adhesive strength between B and the second adhesive layer 3C.

得られるという効果がある。As described above, the present invention is a double-sided pressure-sensitive adhesive sheet for adhering table tennis rubber to a table tennis racket main body, wherein the double-sided pressure-sensitive adhesive sheet is based on a highly resilient vulcanized rubber sheet. Because it is a table tennis rubber adhesive sheet made by applying the front and back double-sided adhesive of the substrate, according to this,
Since the rebound resilience of the pressure-sensitive adhesive sheet itself is significantly improved, by using this pressure-sensitive adhesive sheet when sticking the table tennis racket body and the table tennis rubber, the hit ball repulsion force is reduced by the conventional pressure-sensitive adhesive sheet. There is an effect that a table tennis racket avoiding the above can be obtained.
