Description

  The present invention relates to a coating layer for a golf club head, and in particular, by applying an elastic resin layer containing a matting component on an undercoat paint on the head surface, the surface scattering rate can be increased and surface defects can be hidden. This relates to the structure of the coating layer.

  The sport of golf is usually performed outdoors. When a user picks up a golf club and swings in the sun, the sun's light always illuminates the surface of the golf club head and reflects it to the user. Irradiate to both eyes. If the reflected beam is too bright, the reflected beam will interfere with the user's naked eye, and the user will be unable to hit the ball with a single heart. There was a problem that it was.

  In order to overcome the above-described problems, as shown in FIG. 2, a conventional golf club head is usually coated with an undercoat paint 2 on the head surface 1, and then a matte component 21 is mixed in the undercoat paint 2 in advance. In this way, the undercoat paint 2 not only meets the requirements for rust prevention and decoration, but can further increase the light scattering rate appropriately. As a result, the light incident by the matte component 21 of the undercoat paint 2 can be appropriately scattered, so that the intensity of the reflected light can be reduced, and the reflected light affects the user's intended operation. There are things that you can avoid.

In addition, as a method of manufacturing a golf club head, the charged paint is sprayed in a mist form by an electrostatic coating machine, and the metal golf club head is sequentially passed through the spray space where the mist paint is sprayed. In some cases, the golf club head can be painted (see, for example, Patent Document 1).

  In the structure of the conventional golf club head as described above, when the light beam is projected to the surface of the undercoat paint 2, the surface of the undercoat paint 2 itself has a reflection ability, and further, the matte component 21 exposed on the surface. Are limited so that most of the light rays are actually reflected directly from the undercoat paint 2 itself. Based on the above-mentioned causes, even if the matting component 21 is directly mixed into the undercoat paint 2, the scattering effect is limited to the surface, and the matting component 21 in the undercoat paint 2 effectively exhibits the scattering effect. Can not do it. Furthermore, if a part of the light beam is projected to the surface defect 22 of the undercoat paint 2, the light beam can be reflected only to the outside with sufficient brightness because only a limited scattering occurs. . As a result, the surface defects 22 of the undercoat paint 2 can be easily seen with the naked eye, so that the yield of the product is lowered or the head surface 1 must be subjected to a hub polishing process. There was a problem. Therefore, the structure of the conventional golf club head as described above must be further improved.

  The present invention was invented in view of such problems, and the object of the present invention is to apply an elastic resin layer to the undercoat paint on the head surface, and a matte component is mixed in the elastic resin layer in advance.

Therefore, it is an object of the present invention to provide a coating layer for a golf club head that can enhance surface scattering rate, visual effect and touch.

  The second object of the present invention is to protect the undercoat paint and prevent fading by applying an elastic resin layer in the undercoat paint on the head surface, so that the durability of the undercoat paint can be improved. It is intended to provide a coating layer for the head.

  The third object of the present invention is to apply an elastic resin layer to the undercoat paint on the head surface and adjust the thickness of the elastic resin layer to form a vibration damping effect due to elasticity. An object of the present invention is to provide a coating layer for a golf club head that can enhance the properties.

  The fourth object of the present invention is to apply an elastic resin layer in the undercoat paint on the head surface and add a curing agent appropriately to the elastic resin layer so that a uniform and relatively thick thickness is formed. It is an object of the present invention to provide a golf club head coating layer capable of increasing the uniformity of the layer.

In order to achieve the above object, the coating layer of the golf club head according to the present invention is as follows. That is,
Consists of undercoat paint, elastic resin layer and matte component. The undercoat paint is applied to the head surface, and the light can be reflected by the undercoat paint. The elastic resin layer is applied on the undercoat paint, and the light beam can pass through the elastic resin layer. The matting component is mixed in the elastic resin layer in advance, and the above-mentioned light beam can be scattered by the matting component. When the light beam is incident on the elastic resin layer, the matte component in the elastic resin layer provides a double scattering effect, which can relatively weaken the intensity of the light beam reflected from the undercoat paint. it can.

Further, the matting component can be selected from fine powdered silicon dioxide, talc, aluminum stearate, calcium stearate, and low molecular elastic resin. In addition, when the elastic resin layer is applied, the curing speed of the elastic resin layer can be increased by adding a curing agent to the paint of the elastic resin layer.

  According to the coating layer of the golf club head of the present invention, by applying an elastic resin layer having a matte effect on the undercoat paint on the head surface, double deep scattering is formed and surface defects of the undercoat paint Can be effectively concealed, which has the advantage that the surface scattering rate, visual effect and tactile sensation can be enhanced.

  According to the coating layer of the golf club head of the present invention, a uniform and relatively thick thickness is formed by applying an elastic resin layer to the undercoat paint on the head surface and appropriately adding a curing agent to the elastic resin layer. Therefore, there is an advantage that the uniformity of the coating layer can be increased.

  Embodiments of the present invention will be described below with reference to the drawings.

  Referring to FIG. 1, a coating layer of a golf club head according to an embodiment of the present invention is applied with an undercoat paint 2 and an elastic resin layer 3 in order on the head surface 1. The head surface 1 can be selected from any part of a golf club head having any material and type, for example, a wood-type club, an iron-type club or a putter head made of a material such as metal, alloy, or carbon. The crown plate, the sole plate, the side plate, the face plate, or the lid plate can be selected. The undercoat paint 2 can preferably be selected from highly reflective paints, such as phenolic aldehyde paint, alcoholic acid paint, polyurethane paint, nitro-based paint, polyester paint, and acrylic paint. The undercoat paint 2 can be applied to the head surface 1 by a method such as stretch coating, spray coating, or dipping. The undercoat paint 2 can be selected from different facial colors, and the thickness applied by the undercoat paint 2 is preferably between 10 μm and 100 μm, in particular between 20 μm and 40 μm. In addition, the presence of a small number of surface defects 22 on the surface of the head surface 1 itself is an unavoidable problem.

  Referring to FIG. 1 again, the elastic resin layer 3 of the present invention is usually made of a transparent elastic material, and the elastic resin layer 3 has a property of high penetrability and low reflectivity. (PU, polyurethane), rubber, thermoplastic elastomer or polymer elastic resin. The elastic resin layer 3 is blended with an appropriate organic solvent and further applied onto the undercoat paint 2 by a method such as stretching, spraying or dipping. The thickness to which the elastic resin layer 3 is applied is preferably between 20 μm and 200 μm. In particular, it is interposed between 20 μm and 200 μm. The matting component 31 is mixed in the elastic resin layer 3 in advance, and the matting component 31 can be selected from materials having good scattering properties. For example, fine powdered silicon dioxide, talc, aluminum stearate, calcium stearate And can be selected from low-molecular elastic resins and the like.

  Referring again to FIG. 1, when the user uses the golf club head of the present invention under the sunlight, the light beam is first projected to the elastic resin layer 3. At this time, since the elastic resin layer 3 itself has a low reflectance and belongs to a transparent material, the light beam can enter the elastic resin layer 3, and further, all the matting components 31 in the elastic resin layer 3 are used. Scattering action. Since the scattering action does not limit only the surface of the elastic resin layer 3, it is formed to have a relatively good scattering effect. Then, the scattered light can be projected to the surface of the undercoat paint 2 along substantially the same incident angle. At this time, the light beam is normally formed so as to be reflected directly from the surface of the undercoat paint 2 and emitted outward. Regardless of the angle at which the light beam is incident or reflected, the light beam must pass through the elastic resin layer 3 again in the reflection period, and to reduce the intensity of the light beam, the matte component 31 must be used to perform the re-shooting again. I must. As a result, when the golf club head is viewed with the naked eye, the intensity of the reflected light of the undercoat paint 2 has already weakened, so that the user is not dazzled. Even if a small number of surface defects 22 are formed on the surface of the undercoat paint 2, the intensity of light emitted by the effect of the relatively good double scattering that the matting component 31 has is slightly weak. It can be effectively concealed, and the flatness requirement on the surface of the undercoat paint 2 can be relatively reduced.

  Further, since the elastic resin layer 3 is applied above the undercoat paint 2, the undercoat paint 2 can be prevented from being worn out, discolored, oxidized, or dropped, and has a relatively good elastic touch. In addition, since the elastic resin layer 3 itself has the ability of vibration control by elasticity, by increasing the thickness of the elastic resin layer 3, it is possible to form a vibration suppression effect by appropriate elasticity in the present invention. . If the undercoat paint 2 and the elastic resin layer 3 are applied to the back surface of the face plate of the golf club head, the aftershock of the hit ball can be absorbed, or the deformability due to the elasticity of the face plate can be adjusted to a small width.

  In addition, the head surface 1 is always required to have various irregular shapes such as surface curvature changes, corner bends or undercuts according to the demands of the product. Therefore, when applying the coating of the elastic resin layer 3, the coating at a relatively high position tends to flow toward the lower position due to gravity, and therefore, the formation of a uniform elastic resin layer 3 is achieved. Will be disadvantaged. In the coating operation, when the thickness of the elastic resin layer 3 is increased, the above uniformity problem becomes more apparent. Therefore, if an attempt is made to increase the thickness of the elastic resin layer 3 according to the demand of the product, in the present invention, an extra curing agent applied to the elastic resin material is added to the paint of the elastic resin layer 3, By appropriately increasing the degree of adhesion and the molecular connection speed, the speed of curing by applying the elastic resin layer 3 can be increased, so that the elastic resin layer 3 having a uniform thickness can be formed.

  As described above, according to the coating layer of the conventional golf club head shown in FIG. 2, the matting component 21 is directly mixed in the undercoat paint 2, but there is a problem that a good scattering effect cannot be obtained. However, according to the coating layer of the golf club head of the present invention shown in FIG. 1, the elastic resin layer 3 is applied on the undercoat paint 2, and the matting component 31 is mixed into the elastic resin layer 3. In addition to increasing the scattering rate of the surface, the visual effect, tactile sensation and vibration control can be improved, and further, the undercoat paint can be protected and the added value of the head can be increased.

  The present invention may be implemented in other ways without departing from the spirit and essential characteristics thereof. Accordingly, the preferred embodiments described herein are illustrative and not limiting.
