【発明の詳細な説明】
〈産業上の利用分野〉
本発明は、耐衝撃性、耐摩耗性、耐擦傷性、耐候性等に
優れたゴルフボール用塗料組成物に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a golf ball coating composition that has excellent impact resistance, abrasion resistance, scratch resistance, weather resistance, etc.
〈従来の技術およびその問題点〉
ゴルフボール用塗料に要求される塗膜性能として、美的
外観の他にゴルフボールの伸縮に追随する柔軟性、硬い
ヘッドによるインパクトに耐えうる耐衝撃性、使用瑚境
における接触物との摩擦に耐えうる耐摩耗性、耐擦傷性
、屋外の使用に耐えうる耐候性などが挙げられる。<Conventional technology and its problems> In addition to aesthetic appearance, the film performance required for golf ball paints is flexibility that follows the expansion and contraction of the golf ball, impact resistance that can withstand impact from a hard head, and ease of use. These include abrasion resistance that can withstand friction with objects that come into contact with the product in the environment, abrasion resistance that can withstand outdoor use, and so on.
従来、このような要求をある程度溝たす塗料として、ポ
リエステルポリオールあるいはポリエーテルポリオール
とポリイソシアネートからなる二液型ポリウレタン樹脂
塗料があるが、前記要求性能を全て完全に満たす塗料は
未だ知られていない。Conventionally, two-component polyurethane resin paints made of polyester polyol or polyether polyol and polyisocyanate have been available as paints that meet these requirements to some extent, but no paint that completely satisfies all of the above-mentioned performance requirements has yet been known. .
ポリオールとしてポリエステルポリオールを使用した二
液型ポリウレタン樹脂塗料は、塗膜強度に優れているが
、硬度が高く耐衝撃性が一般的に悪い。そこで、水酸基
価の小さいポリエステルポリオールを使用するか、また
はポリイソシアネートの配合量を少なくする方法も考え
られているが、これら方法もある程度塗膜の柔軟性が改
善されるが耐摩耗性が低下したり、硬化速度が遅くなる
などの問題が生じる。Two-component polyurethane resin paints using polyester polyols as polyols have excellent coating strength, but have high hardness and generally poor impact resistance. Therefore, methods of using a polyester polyol with a low hydroxyl value or reducing the amount of polyisocyanate blended are considered, but these methods also improve the flexibility of the coating film to some extent, but the abrasion resistance decreases. Problems may arise, such as slow curing speed.
また、ポリオールとしてポリエーテルポリオールを使用
した二液型ポリウレタン樹脂塗料は柔軟な塗膜が得られ
やすいが、分子間力が強くないため耐擦傷性等が劣る傾
向にある。そこでポリエーテルポリオールの分子鎖中に
芳香環などの剛直な基を導入したり、活性水素化合物を

なるなどの問題が生じる。Furthermore, two-component polyurethane resin paints that use polyether polyol as the polyol tend to provide a flexible coating film, but they tend to have poor scratch resistance because their intermolecular forces are not strong. Therefore, methods have been considered to introduce rigid groups such as aromatic rings into the molecular chain of polyether polyol, or to use active hydrogen compounds in combination, but these methods also improve abrasion resistance and frostbite resistance. However, problems such as poor impact resistance occur.

られる。In the present invention, a polycarbonate diol represented by the above general formula is used as an essential component as a polyol constituting the main component. Polycarbonate diol is a conventionally known compound, and is usually obtained by reacting a polyhydric alcohol with phosgene or an organic carbonate by a conventional method. Specifically, examples of polyhydric alcohols include 1,4-butanediol, 1,6-hexanediol, ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, hexylene glycol, and 2-ethyl-1. , 3-hexanediol,
Representative examples include 1,5-bentanediol and i,41-cyclohexanediol. In particular, in the present invention, polycarbonate diol produced using 1,4-butanediol and 1,6-hexanediol as the polyhydric alcohol can be suitably used since it has good compatibility with polyisocyanate and good coating film properties. In addition, examples of organic carbonates include diethyl carbonate, dimethyl carbonate, diphenyl carbonate,
Typical examples include ethylene carbonate, trimethylene carbonate, and tetramethylene carbonate.

耐擦傷性等のいずれかが悪くなる傾向にある。Other polyols that can be used include polyester polyols or polyethylene glycols, which are reaction products of polybasic acids such as adipic acid and phthalic anhydride and polyhydric alcohols such as ethylene glycol, diethylene glycol, propylene glycol, trimethylolpropane, and glycerin; Typical examples include polypropylene glycol, polytetramethylene glycol, and polyether polyols that are derivatives of these polyethers. The blending ratio of polycarbonate diol and other polyols depends on the type of the latter, but it is generally desirable that the former be at least 30% by weight, preferably at least 50% by weight. If the amount is less than this range, the toughness due to polycarbonate diol will not be developed, and the impact resistance, abrasion resistance, and

On the other hand, if it is larger than the above range, the resulting coating film will have too high a crosslinking density, become hard, and have poor impact resistance, so either case is not preferable.

A range of 0 is preferable. If the polyisocyanate is in excess of the above range, it will react with moisture in the air, resulting in poor scratch resistance and difficulty in obtaining a smooth coating film. On the other hand, if the amount of polyisocyanate is too small, drying will be delayed, the coating film will tend to remain sticky, and water resistance will also deteriorate, so either case is not preferable.
