Description
試験片のゴム硬度を、JIS K6253に準拠しデュロメータのタイプAにより温度25℃で測定した。得られた結果は、表1の「ゴム硬度」の欄に示した。
得られた試験片から、JIS K6251に準拠してJIS3号ダンベル型試験片を切り出した。JIS K6251に準拠し400%変形時の応力を測定した。得られた結果は、表1の「M400(S)」の欄に示した。
得られた試験片の動的粘弾性を、東洋精機製作所社製粘弾性スペクトロメーターを用いて、初期歪み10%、振幅±2%、周波数20Hzで測定し、温度0℃におけるtanδを算出した。得られた結果は、比較例1の値を100とする指数で表わし表1の「tanδ(0℃)」の欄に示した。この指数が大きいほどウェット性能が優れることを意味する。
得られた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−1.5℃、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、比較例1の値を100とする指数で表わし表1の「氷雪上性能」の欄に示した。この指数が大きいほど氷雪上性能が優れることを意味する。
スタッドピンのチップ部を取り除いたのち、その頂部にねじ穴を作成して、つかみ代を有する雄ねじをはめ込んだ。このように加工したスタッドピンを、上記で作成した植え込み穴付き試験片に埋設し、状態調整をした後、引張り試験機にかけてスタッドピンの引抜き力を測定した。得られた結果は、表1の「引抜き力」の欄に示した。
