Description
表Iに示す配合において、加硫促進剤と硫黄を除く成分を1.8リットルの密閉型ミキサーで5分間混練し、140℃に達したときに放出してマスターバッチを得た。このマスターバッチに加硫促進剤と硫黄をオープンロールで混練し、ゴム組成物を得た。このゴム組成物の非石油系原料比率(%)を表Iに示す。
粘弾性測定(0℃及び60℃のtanδ)にてウェット性能及び転がり抵抗を評価した。粘弾性測定は以下のようにして実施した。
東洋精機製の粘弾性スペクトロメーターを用い、伸長変形歪率10±2%、振動数20Hzの条件で測定した。
性能は比較例1を基準に指数表示した。なお、ウェット性能については、指数の値が高いほど0℃のtanδの値が大きい(性能良好である)ことを示している。また転がり抵抗については、指数の値が高いほど60℃のtanδの値が小さい(性能良好である)ことを示しており、どちらの性能も、この指数の値が高いほど性能良好であることを示す。
