Abstract
Description
得られたタイヤ用ゴム組成物を、所定形状の金型(内寸:長さ150mm、幅150mm、厚さ2mm)を用いて170℃、10分間加硫し、加硫ゴム試験片を作成した。その加硫ゴム試験片を使用し、JIS K6251に準拠してダンベルJIS3号形試験片を作製し、室温(20℃)で500mm/分の引張り速度で引張り試験を行い、破断したときの引張り破断伸びを測定した。得られた結果は、標準例1の値を100とする指数として、表1の「破断伸び(EB)」の欄に示した。この指数値が大きいほど引張破断伸びが大きい(引張特性が良好である)ことを意味する。尚、指数値が「90」以上であれば、標準例1と同程度の良好な引張特性を維持している。
得られたタイヤ用ゴム組成物を、所定形状の金型(内寸:長さ150mm、幅150mm、厚さ2mm)を用いて170℃、10分間加硫し、加硫ゴム試験片を作成した。その加硫ゴム試験片を偏平円柱状の台ゴムに貼り付け、インサイドドラム型氷上摩擦試験機を用いて、測定温度−3.0℃、荷重5.5kg/cm2 、ドラム回転速度25km/hの条件で氷上摩擦係数を測定した。得られた結果は、標準例1の値を100とする指数として、表1の「氷上性能」の欄に示した。この指数が大きいほど氷上摩擦力が大きく氷上性能に優れることを意味する。
