Description
【考案の詳細な説明】 （産業上の利用分野） 本考案はゴルフクラブヘツドに関する。[Detailed explanation of the idea] (Industrial application field) The present invention relates to golf club heads.

された（特開昭60−031772）。(Prior art and its problems) In conventional wood-type golf club heads, the face surface where the golf ball is hit is made of ABS resin,
Carbon fiber-reinforced polyester resin, epoxy resin, or metal was used, and the entire head was coated with urethane-based clear paint. Later, with the advent of the two-piece ball, research was conducted into materials for the face that would fit well with the ball, and ionomer resin was proposed as a preferred material (Japanese Patent Laid-Open No. 60-031772).
しかし、フエース材料としてアイオノマー樹脂
を使用すると、従来のウレタン系クリヤーペイン

ないクラブヘツドの開発が望まれていた。 However, when ionomer resin is used as the face material, conventional urethane-based clear paint has the drawback that the clear paint peels off when a golf ball is hit, reducing the commercial value of the golf club, and the paint does not peel off. The development of a club head was desired.
（問題点を解決する手段）
本考案は上記のような問題点を解決するため

大幅に改善する。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has been developed by coating only the face surface or the entire head of the club head with an undercoat consisting of polyamide resin and bisphenol A in a color number of 4 or less. Apply epoxy clear paint, and as a top coat, elongation at break is 30% or more, strength at 10% elongation is 100Kg/cm 2 or more,
By applying a urethane-based clear paint of 250 kg/cm 2 or less to the entire head, the deterioration in appearance of the head caused by using the club can be greatly improved.

オノマー樹脂としては、デユポン社製のサーリン
1706，1605，1707等が挙げられる。 The material for the face of the club head used in this invention may be a single ionomer resin or a blend of resins such as nylon, ABS, and polycarbonate up to 30%, and each may contain inorganic fillers, pigments (inorganic, organic ), dispersing agents (for example, zinc stearate, etc.), ultraviolet absorbers, antioxidants, crystal nucleating agents, etc. may be added. As an ionomer resin, Surlyn manufactured by DuPont
Examples include 1706, 1605, 1707, etc.
本考案に用いるエポキシ系クリヤーペイント

ルＡより成るが、エポキシペイントは通常褐色に
変色しているため、クリヤー塗布するために精製
して用いるのが好ましい。又適宜紫外線吸収剤を
添加する事も耐候性を上げるのに効果がある。 The epoxy clear paint used in the present invention is composed of polyamide resin and bisphenol A as described above, but since epoxy paint usually has a brown color, it is preferable to refine it before use for clear coating. Adding an appropriate ultraviolet absorber is also effective in increasing weather resistance.
特に好ましいエポキシ系クリヤーペイントは、
ビスフエノールＡ系ポリアミド樹脂を主剤とし高
度に精製されたダイマー酸を原料として合成され
たポリアミド樹脂を硬化剤とするものである。 Particularly preferred epoxy clear paints are:
The curing agent is a polyamide resin synthesized using a bisphenol A-based polyamide resin as a main ingredient and a highly purified dimer acid as a raw material.
一般にエポキシ塗料材料として用いられるダイ

品は約８）を用いる。 Dimer acid, which is generally used as an epoxy coating material, has a dimer acid content of 75% by weight or more, a trimer acid content of about 20% by weight, and a monomer acid content of 5% by weight.
It has been used to some extent. Therefore, the equivalence reaction of the polyamine does not proceed, and low molecular weight impurities that are easily oxidized are generated, causing coloration. In the present invention, a polyamide resin having a dimer acid content of 90% by weight or more and purified to a monomer content of 1.5% by weight or less is used as a curing agent. In particular, use colors with a number of 4 or less (conventional products have about 8).
又接着性を更に向上させるため顔料にチタンカ
ツプリング剤、シランカツプリング剤等を添加し

前述の下塗層、上塗層は、それぞれ一層又は数
層の重ね塗りをしてもよい。 In order to improve impact resistance, abrasion resistance, and weather resistance of the urethane-based clear used as a top coat, it is preferable to use non-yellowing type isocyanates such as hexamethylene diisocyanate and its derivatives, isophorone diisocyanate, etc. . or,
Elongation at break is 30% or more, strength at 10% elongation is 100
Use materials with physical properties of Kg/cm 2 or more and 250Kg/cm 2 or less. Anything outside this range will cause cracks when the ball is hit, have poor durability such as impact resistance and abrasion resistance, and be unfavorable in terms of appearance. It may be applied in one layer or in several layers.
