Abstract
Description
1.少なくとも1層のコアを具備するゴルフボールであって、該ゴルフボールは、艶消し粒子を含むコーティング層を表面に有し、該コーティング層の表面の平均粗さRaは0.5〜1.0であることを特徴とするゴルフボール。
2.上記艶消し粒子の比表面積がBET比表面積で200〜400m2/gである上記1記載のゴルフボール。
3.上記艶消し粒子の粒径が、平均一次粒子径で1.0〜3.0μmである上記1又は2記載のゴルフボール。
4.上記艶消し粒子の配合量は、コーティング層の主剤(樹脂成分と溶剤との合計量)100質量部に対して5〜10質量部である上記1〜3のいずれかに記載のゴルフボール。
5.上記コーティング層の光沢度計による反射率は、入射角20°では5.0以下であり、入射角60°では20.0以下であり、且つ、入射角85°では40.0以下である上記1〜4のいずれかに記載のゴルフボール。
本発明のゴルフボールは、少なくとも1層のコアを具備し、艶消し粒子を含むコーティング層を表面に有する。
上記塗料用組成物としては、特に制限はないが、ウレタン系塗料を用いることが好適である。ゴルフボールの過酷な使用状況に耐えうる必要から、2液硬化型のウレタン塗料、特に、無黄変のウレタン塗料が好適に挙げられる。
下記表1に示すように、全ての例に共通する下記のゴム組成物を用い、155℃で15分間の加硫により、各例のソリッドコアを作成した。
・「ポリブタジエンゴム」 JSR社製、商品名「BR01」
・「有機過酸化物」 ジクミルパーオキサイド、日油製の商品名「パークミルD」
・「硫酸バリウム」 堺化学工業社製
・「酸化亜鉛」 堺化学工業社製
・「アクリル酸亜鉛」 日本触媒社製
・「ペンタクロロチオフェノール亜鉛塩」 和光純薬工業社製
次に、上記で得た直径37.3mmのコアの周囲に、全ての例に共通する下記表2に示す厚さ1.35mmの中間層を射出成形法により被覆して、直径(外径)が40mmの中間層被覆球体を製造した。次に、上記中間層被覆球体の周囲に、同表に示す厚さ1.35mmの最外層材料を射出成形法により被覆して、ボール直径42.7mmのスリーピースゴルフボールを作製した。この際、各実施例、比較例の最外層表面には、特に図示してはいないが、共通するディンプルが形成された。
・「HPF1000」:デュポン社製のアイオノマー樹脂材料
・「ハイミラン1605」「ハイミラン1557」:三井・デュポンポリケミカル社製のアイオノマー樹脂
・酸化チタン:白色顔料
(i)先ず、環流冷却管、滴下漏斗、ガス導入管及び温度計を備えた反応装置に、トリメチロールプロパン140質量部、エチレングリコール95質量部、アジピン酸157質量部、1,4−シクロヘキサンジメタノール58質量部を仕込み、撹拌しながら200〜240℃まで昇温させ、5時間加熱(反応)させた。その後、酸価4,水酸基価170,重量平均分子量(Mw)28,000の「飽和ポリエステルポリオール」を得た。
(ii)次に、上記の合成したポリエステルポリオールを酢酸ブチルで溶解させ、不揮発分70質量%のワニスを調整した。
(iii)上記飽和ポリエステルポリオール溶液27.5質量部に対して、酢酸ブチルで溶解させ(この溶液の不揮発分27.5質量%)、艶消し粒子としては、表4に示すように、粒子径及び比表面積が異なる艶消し粒子を所定量含有した。
「P−2」〜「P−6」:EVONIC INDUSTRIESの「ACEMATT」シリーズ
得られた各実施例及び比較例のゴルフボールについては、ゴルフ打撃ロボットにサンドウエッジ(SW)をつけて、ヘッドスピード20m/sにて打撃した時のスピンの量で判断し、クラブは、ブリヂストンスポーツ社製の「TourB XW−1 SW」を使用した。そのスピン量を表5に示す。
ゴルフボール表面(コーティング層)の光沢性を下記のとおり評価した。BYK社製「micro-TRI-gloss」により、測定入射角度20°/60°/85°による光沢度を計測した。各測定角度の光沢度の数値については、入射角20°で5.0以下、入射角60°で20.0以下、入射角85°で40.0以下となれば、光沢性が十分に抑えられているとして「○」と評価し、それ以外は、光沢性があるとして「×」と評価した。
ミツトヨ社製の表面粗さ測定器(SV−C3000)を用いて、コーティング層を有するゴルフボールの表面の粗さを測定した。この塗膜の表面粗さRaは、JIS B0601(1994)の算術平均粗さに基づく。
これに対して、比較例1,4のゴルフボールは、コーティング層の光沢性が少なく、艶消し効果が高いが、アプローチ時のスピン量が実施例1,2より低くなる。
また、比較例2,3及び5のゴルフボールは、アプローチ時のスピン量は多いが、コーティング層は光沢性が高くなってしまう。
