Problems solved by technology

But adopting this kind of film layer can easily increase the surface hardness of the racket string. Although it can increase the friction force to make the ball rotate, it will increase the hardness of the racket surface and may affect the elasticity of the racket. Coating material for further improvement

Embodiment 1

[0013] The invention discloses a coating for racket strings, which comprises the following raw materials in parts by mass: 75 parts of polyurethane resin, 15 parts of graphene resin, 10 parts of cellulose acetate butyrate, and 5 parts of nickel metal powder.

[0014] Using this combination method, the graphene resin and cellulose acetate butyrate will produce a chemical reaction during the combination process, which can improve the surface activity of the polyurethane resin, thereby improving the surface softness of the net string, so that it can be used without affecting Under the premise of tennis line wear resistance and friction, the tennis line is more elastic. The addition of nickel metal powder in the coating can further improve the wear resistance of the tennis line and improve the quality and service life of the racket.

Embodiment 2

[0016] The invention discloses a coating for racket strings, which comprises the following raw materials in parts by mass: 65 parts of polyurethane resin, 20 parts of graphene resin, 15 parts of cellulose acetate butyrate, and 5 parts of zinc metal powder.

[0017] Using this combination method, the graphene resin and cellulose acetate butyrate will produce a chemical reaction during the combination process, which can improve the surface activity of the polyurethane resin, thereby improving the surface softness of the net string, so that it can be used without affecting Under the premise of tennis line wear resistance and friction, the tennis line is more elastic. Adding zinc metal powder to the coating can further improve the wear resistance of the tennis line and improve the quality and service life of the racket.

Embodiment 3

[0019] The invention discloses a coating for racket strings, which comprises the following raw materials in parts by mass: 55 parts of polyurethane resin, 20 parts of graphene resin, and 15 parts of cellulose acetate butyrate.

[0020] Using this combination method, the graphene resin and cellulose acetate butyrate will produce a chemical reaction during the combination process, which can improve the surface activity of the polyurethane resin, thereby improving the surface softness of the net string, so that it can be used without affecting Under the premise of tennis line wear resistance and friction, the tennis line is more elastic.

[0021] The invention also discloses a racket, the racket string includes a filamentary racket string, the racket string is coated with a coating, and the material of the coating includes the following raw materials in parts by mass: 55-75 parts of polyurethane resin, graphite Vinyl resin 10-20 parts, cellulose acetate butyrate 10-15 parts. The...

Abstract

The invention discloses a coating for a racket string. The coating comprises the following raw materials in parts by mass of 55-75 parts of polyurethane resin, 10-20 parts of graphene resin and 10-15parts of cellulose acetate butyrate. Graphene resin and cellulose acetate butyrate are arranged in the racket string coating, a chemical reaction is generated in the binding process, the surface activity of the polyurethane resin can be improved, the surface softness of the tennis ball net line can be improved, the tennis ball net line is more elastic on the premise of not reducing the abrasion resistance and friction force of the tennis ball line, and then the competition level of a competitor is improved.

Description

technical field [0001] The invention relates to the technical field of sporting goods, in particular to a coating used for tennis racket strings and a racket using the coating. Background technique [0002] Tennis is widely welcomed as a kind of ball game. In addition to the skills of the players themselves, the quality of the racket will also have a certain impact on the performance of the game. For this reason, tennis racket manufacturers often choose tennis rackets The material and the material of the racket string are improved, so that the quality of the racket is lighter and the elasticity of the racket string is better. The invention patent (patent number: (201780024134.9) discloses a racket string that can improve the spin performance. The racket string is set to have a filamentary structure and a coating film formed around the filamentary structure. The structure in which the surface friction force of the layer film is 9 N or more. This increases the surface frictio...
