Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club head, and more particularly to a golf club head in which a head body made of metal or the like is coated with a novel coating.

[0002]

2. Description of the Related Art Golf club heads, particularly wood type heads, tend to be large-sized for the purpose of increasing the flight distance and the directionality of hit balls. Further, the appearance of such a golf club head has been further improved, and, for example, various paints for coating the head body have been tried in consideration of colors and color tones. Specifically, for example, in order to make the appearance of the head more brilliant compared to the conventional solid type coloring coating and metal coating, a head that has applied a polarizing paint kneaded with mica foil having polarizing properties has appeared I have.

[0003] In this case, the coating of the head using the above-mentioned polarizing paint (so-called pearl coating) is generally performed by the following method. That is, first, a base treatment such as polishing, primer coating, and filling a pinhole is applied to the head body.
Next, an existing color paint is applied to the surface of the head main body to form a colored layer, and a polarizing paint is thinly overcoated thereon. Finally, the surface of the polarizing paint layer is coated with a clear glazing. The above-mentioned polarizing paint is obtained by kneading a polarizing material such as mica into a paste with a plasticizer and making the paste into a liquid state by using a slight solvent or clear (transparent paint).

[0004]

However, the head coated with the above-mentioned polarizing paint (so-called pearl coating) can certainly give a brilliant texture, but on the other hand, there is criticism that it is too flashy, It was not satisfactory in terms of merchantability. In addition, when the club head is set to the address state, if it is exposed to strong sunlight, the head may be dazzled, making it difficult to check the orientation of the face. Was.

[0005] Further, as described above, the coating of the head using the polarizing paint requires at least three painting operations of painting a color paint, painting a polarizing paint, and applying a clear glazing. However, there has been a problem that the production cost is high, which is not suitable for mass production. In addition, a thin overcoating operation of the polarizing paint requires a high level of skill because the method of spraying the polarizing paint tends to vary, and when the skill is low, uneven color, unevenness of the polarizing material, unevenness of shading, etc. The problem described above easily occurred. In addition, a thin spray coating of a polarizing paint requires a spray gun with special specifications, which also causes an increase in cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is directed to a golf club having a pearl coating, which is free from excessive flashy head colors, has little glare at the time of addressing, and has a paint coating. It is an object of the present invention to provide a golf club head whose process is simple.

[0007]

According to the present invention, in order to achieve the above object, a colored polarizing paint layer made of a colored polarizing paint obtained by mixing a polarizing paint and a colored paint is provided on the surface of a head body subjected to a base treatment. A golf club head is provided, wherein a glazed clear layer is formed on the colored polarizing paint layer.

In the present invention, in performing pearl coating, a colored polarizing paint is prepared by mixing a polarized paint and a colored paint of a predetermined color in advance, and this is coated on the surface of the head body which has been subjected to a normal base treatment. After application, a glazed clear layer is formed thereon. Therefore, the original glitter of the polarizing pigment is suppressed by the coloring agent contained in the coloring paint, the flashiness is reduced from the color tone of the painted club head, and a calm color tone is obtained. In addition, glare on the head surface is reduced when addressing outdoors in strong sunlight, making it easier to check the face orientation and the like, making it easier to hold the club. Also noteworthy is the striking difference in the color and tone of the head surface due to the intensity of the light striking the head. And under a weak light source indoors, a calm texture similar to solid type painting appears,
A golf club head having excellent appearance characteristics is obtained.

Conventionally, two layers, a colored layer made of color paint and a polarizing paint layer, are formed to perform pearl coating. On the other hand, in the present invention, the functions of the two layers are replaced by one colored polarizing paint layer. Is achieved, the number of coatings is reduced by one, and the coating process is simplified, and the conventional thin coating operation of the polarizing paint is eliminated, so that a high degree of skill and a special spray gun are not required. Accordingly, mass production of the club head with the pearl coating and a reduction in manufacturing cost are facilitated.

Hereinafter, the present invention will be described in more detail. In the golf club head of the present invention, for example, a head body (a head before applying a base treatment and coating) made of a metal such as a titanium alloy, stainless steel, or steel can be used, but is not limited thereto. Not something.

[0011] Examples of the base treatment to be applied to the head body include polishing, primer coating, and filling of pinholes. Polishing is a process of polishing the head main body by wire brushing, sand blasting or the like. Primer coating consists of applying a liquid thermosetting polyester-based primer or the like to the polished head body to create a film chemically bonded to the metal base, and to create pinholes on the surface of the head body generated during the manufacture of the head body This is a step of making it easier to detect The filling of the pinhole is a process of repairing the pinhole by filling the pinhole on the surface of the head body where the two-liquid type putty material or the like is detected.

In the present invention, a colored polarizing paint layer is formed on the surface of the head body subjected to the above-described undercoating treatment by using a colored polarizing paint obtained by mixing a polarizing paint and a colored paint. In this case, as the polarizing paint, any paint can be used as long as it contains a polarizing material. For example, the polarizing material is kneaded into a paste with a plasticizer, and the paste is mixed with a solvent or clear (transparent paint) to form a liquid. Can be used. Further, the type of the polarizing material is not limited,
For example, a mica foil or a mica foil coated with a coating agent such as basic lead carbonate or titanium dioxide, and a natural shell powder can be suitably used. In addition, as the coloring paint, a normal paint containing a coloring pigment can be used.

In the present invention, the mixing ratio (weight ratio) of the polarizing paint to the coloring paint in the colored polarizing paint is from 5 to 25: 1.
00, particularly 15 to 20: 100, is appropriate in that a good pearl coating is obtained. Further, other optional components may be appropriately added to the colored polarizing paint. Especially,
In the present invention, it is preferable to add an appropriate amount of an antisettling agent such as bentonite or polywax in order to prevent precipitation and solidification of the polarizing coating in the colored polarizing coating. It is appropriate that the thickness of the colored polarizing coating layer is usually about 10 to 30 μm.

In the present invention, a glossy clear layer is formed on the above-mentioned colored polarizing paint layer. In this case, a known material such as a polyester-based urethane paint can be used as the gloss clear.
