Abstract
【解決手段】ゴルフボール2は、球状のコア4と、このコア4の外側に位置するカバー6とを備えている。コア4は、球状のセンター8と、このセンター8の外側に位置する中間層10とを備えている。センター8は、ゴム組成物が架橋されることで成形される。このゴム組成物の基材ゴムの主成分は、ポリブタジエンである。このゴム組成物は、架橋剤として硫黄を含む。センター8の直径は、1mm以上15mm以下である。センター8の中心硬度H1は、20以上50以下である。中間層10の表面硬度H4と最内部の硬度H3との差(H4−H3)は、10以上である。硬度H4と硬度H1との差(H4−H1)は、40以上である。

Description
100質量部のハイシスポリブタジエン(JSR社の商品名「BR−730」)、5質量部の酸化亜鉛、適量の硫酸バリウム、10質量部のシリカ(東ソー・シリカ社の商品名「Nipsil AQ」、3.4質量部の硫黄、2.20質量部の加硫促進剤(前述の「ノクセラーCZ」)及び2.26質量部の他の加硫促進剤(前述の「ソクシノールDG」)を混練し、ゴム組成物(a)を得た。このゴム組成物(a)を共に半球状キャビティを備えた上型及び下型からなる金型に投入し、150℃の温度下で5分間加熱して、直径が5.0mmであるセンターを得た。
センター及び中間層の仕様を下記の表2及び3示される通りとした他は実施例1と同様にして、実施例2から4及び比較例1から4のゴルフボールを得た。センターのゴム組成物の詳細が、下記の表1に示されている。比較例1に係るゴルフボールは、中間層を有さない。
ゴルフラボラトリー社のスイングマシンに、チタンヘッドを備えたドライバー(SRIスポーツ社の商品名「XXIO」、シャフト硬度:R、ロフト角:11.0°)を装着した。ヘッド速度が40m/secである条件でゴルフボールを打撃して、発射地点から静止地点までの距離を測定した。さらに、打撃直後のボール速度及びバックスピン速度も測定した。12回測定されて得られたデータの平均値が、下記の表2及び3に示されている。
上記スイングマシンに、5番アイアン(SRIスポーツ社の商品名「XXIO」、シャフト硬度:R)を装着した。ヘッド速度が34m/secである条件でゴルフボールを打撃して、発射地点から静止地点までの距離を測定した。さらに、打撃直後のボール速度及びバックスピン速度も測定した。12回測定されて得られたデータの平均値が、下記の表2及び3に示されている。
4・・・コア
6・・・カバー
8・・・センター
10・・・中間層
12・・・ディンプル
Claims (5)
