Abstract
Description
得られたタイヤ用ゴム組成物を用いて、所定形状の金型を用いて145℃、35分間加硫し、各タイヤ用ゴム組成物からなる加硫ゴム試験片を作成した。得られた加硫ゴム試験片を使用して各タイヤ用ゴム組成物の0℃におけるtanδを、JIS K6253に準拠して、粘弾性スペクトロメーター(東洋精機製作所社製)を用いて、初期歪み10%、振幅±2%、周波数20Hz、温度0℃の条件で測定した。評価結果は、標準例1の値を100とする指数で示した。この指数値が大きいほど、ウェット性能(ウェットグリップ性能)に優れることを意味する。
得られたタイヤ用ゴム組成物を用いて、所定形状の金型を用いて145℃、35分間加硫し、各タイヤ用ゴム組成物からなる加硫ゴム試験片を作成した。得られた加硫ゴム試験片を使用して各タイヤ用ゴム組成物の損失弾性率E2と複素弾性率E*を測定し、これらの比E2/(E*)2の値を算出し、ドライ性能(ドライ制動性能)の指標とした。尚、損失弾性率E2および複素弾性率E*はそれぞれ、JIS K6394に準拠して、粘弾性スペクトロメーター(東洋精機製作所社製)により、初期歪み10%、振幅±2%、周波数20Hz、温度60℃の条件で測定した。評価結果は、標準例1の値を100とする指数で示した。この指数値が大きいほど、ドライ性能(ドライ制動性能)に優れることを意味する。
前述の14種類のタイヤ用ゴム組成物(標準例1、比較例1~7、実施例1~6)をそれぞれトレッドゴムに使用し、タイヤサイズが255/35ZR19(96Y)である空気入りタイヤ(試験タイヤ)を製造した。このとき、トレッドゴム以外の各部については、すべての試験タイヤで共通とした。これら試験タイヤについて、リムサイズ19×8.5Jのホイールに組み付けて、空気圧を230kPaとして試験車両に装着し、乾燥路面を8000km走行した後の溝深さを測定することにより耐摩耗性を評価した。評価結果は、標準例1の値を100とする指数で示した。この指数が大きいほど、残存する溝深さが大きく、耐摩耗性に優れることを意味する。
