Embodiment 1

[0009] Eucommia gum 100 parts by weight

[0010] Polyolefin 0 parts by weight

[0011] Sulfur 0 parts by weight

[0012] The materials of the above formula were refined on the open mill at 95°C for 10 minutes, and the handle was pressed out using the mold of the racket handle at 105°C for 2 minutes, and bonded to the racket body with epoxy resin to form a hand-shaped self- Adapt to the racket. The racket prepared in this way has a low deformation temperature (about 60° C.), requires the least force for deformation, and has a large amount of deformation in the hand. It is suitable for occasions requiring a large deformation handle, but there is a certain amount of residual deformation after repeated heating.

Embodiment 2

[0014] Eucommia gum 100 parts by weight

[0015] 20 parts by weight of polypropylene

[0016] Sulfur 0.5 parts by weight

[0017] Mix the materials of the above formula on an open mill at 170°C for 10 minutes, use the mold of the racket handle to press the handle at 178°C for 15 minutes, and bond it to the racket body with epoxy resin to become a hand-shaped self-adaptive racket. The deformation temperature of the racket prepared in this way is slightly higher (about 75° C.), the force required for deformation is relatively large, and the amount of deformation in the hand is relatively low.

Embodiment 3

[0019] Eucommia gum 100 parts by weight

[0020] 20 parts by weight of low-density polyethylene

[0021] Dicumyl peroxide 1.0 parts by weight

[0022] Mix the materials of the above formula on an open mill at 130°C for 10 minutes, use the mold of the racket handle to press the handle at 150°C for 7 minutes, and bond it to the racket body with epoxy resin to become a hand-shaped self-adaptive racket. The racket prepared in this way has a moderate deformation temperature (about 70° C.), moderate force required for deformation, and large amount of deformation in the hand, which is suitable for occasions requiring moderately deformed handles, and the residual deformation after repeated heating is small.

Abstract

A bat or racket adaptive to hand shape is based on an ordinary bat or racket and is prepared through preparing its handle from eucommia gum type high-molecular materials through pugging and die pressing, and adhering it on an ordinary bat or racket. It features that after its handle is slightly heated and then naturally grasped by a user, the handle is deformed to match with its hand shape and then solidified after cooled.

Description

1. Technical field: [0001] The invention relates to a racket, which is composed of eucommia gum or trans polyisoprene macromolecule composite material as a hand-shaped self-adapting racket handle bonded to the racket body. 2. Background technology: [0002] Currently used rackets include: table tennis rackets, badminton rackets, tennis rackets, golf rackets, cricket rackets and the like. This type of sports is different from football, basketball and other sports in which the human body directly contacts the ball, and is carried out by hitting the ball with a racket. Racquet-holding sports competition requires athletes to maintain optimal flexibility in all joints of the body, especially the wrist and fingers, and the hand holding the racket has the greatest explosive power to improve athletic performance. Although the shape of the handle of the current racket is different, it is basically approximately straight stick-shaped or is provided with a general hand-shaped handle. ...
