Description
[1]ゴム組成物の架橋成形物からなるコアをカバーで被覆してなるゴルフボールにおいて前記コアを形成する前記ゴム組成物であり、下記(A)〜(C)成分、
(A)シス−1,4−結合を60質量%以上含有するポリブタジエンを含む基材ゴム、
(B)不飽和カルボン酸及び/又はその金属塩、及び
(C)トリブチルチオウレア
を含有し、かつ上記(C)のトリブチルチオウレアの配合量が、上記(A)成分100質量部に対して0.07〜0.14質量部であることを特徴とするゴルフボール用ゴム組成物。
[2]架橋剤として(D)有機過酸化物を含有する[1]のゴルフボール用ゴム組成物。
本発明は、(A)基材ゴム、(B)不飽和カルボン酸及び/又はその金属塩、及び(C)上記式(1)のチオウレアを配合してなるゴム組成物である。ゴム組成物の配合について以下に具体的に説明する。
(コアの形成)
表1に示す配合のゴム組成物を調製した後、155℃、20分間の条件で加硫成形することにより、同表に示した直径及び重量のコアを作製した。なお、同表中の配合量は質量部で示されている。
(1)コアのたわみ量(mm)
コアを、23±1℃の温度で、10mm/sの速度で圧縮し、初期荷重98N(10kgf)を負荷した状態から終荷重1275N(130kgf)に負荷した時までの、コアのたわみ量(mm)を計測した。
(2)コア初速試験(m/s)
コアの初速は、R&Aの承認する装置であるUSGAのドラム回転式の初速計と同じ方式の初速測定器を用いて測定した。コアは23±1℃の温度で3時間以上温度調節し、室温23±2℃の部屋でテストした。比較例1のコアとの差を表1に示した。
