本発明は、塗膜とゴルフボール表面との接着性を向上さ
せ得るゴルフボールの表面処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for surface treatment of a golf ball that can improve the adhesion between a coating film and the surface of a golf ball.
従来、一般に、ゴルフボールの表面には塗料が塗装され

。Conventionally, the surface of a golf ball is generally coated with paint. This surface painting is done to retain stamped characters, numbers, marks, etc., and to maintain gloss and beauty. Furthermore, in order to increase the adhesion between the paint film and the surface of the golf ball, a brimer is applied to the surface of the golf ball prior to painting.

時間がかかるという問題があった。However, applying such a primer makes the painting process complicated and requires a lot of work time. In particular, since ionomer resins are often used as cover materials for golf balls, this resin has a low melting point and cannot be dried at a high drying temperature, resulting in the problem that it takes a long time to coat.
本発明は、塗膜とゴルフボールの表面との接着性を向上

ことができるゴルフボールの表面処理方法を提供するこ
とを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a golf ball surface treatment method that can improve the adhesion between a coating film and the surface of a golf ball, thereby simplifying the coating process.

れでもよい。The golf ball surface treatment method of the present invention is characterized in that, prior to coating the surface of the golf ball, the surface of the golf ball is irradiated with ultraviolet rays. Here, the golf ball may be a solid golf ball such as a two-piece golf ball, a one-piece golf ball, or a thread-wound golf ball.

向上させることができる。As described above, in the present invention, since the surface of the golf ball is irradiated with ultraviolet rays prior to coating, it is possible to improve the adhesion between the coating film and the surface of the golf ball. This simplifies the painting process because the primer application process can be omitted, and also improves the impact resistance of the paint film since there is no need to use a primer that is weak against bending. I can do it.

is used. The surface cover may be formed by either press molding, which is used for thread-wound golf balls, or injection molding, which is used for solid golf poles. Further, in the present invention, before irradiating with ultraviolet rays, it is preferable to wash the surface of the golf ball with a solvent as necessary in order to remove the mold release agent adhering to the surface of the golf ball.
