Description
上記9種類のタイヤ用ゴム組成物の密閉型ミキサーでの混練終了時において、放出されたゴム組成物におけるシリカの取り込み性を目視観察した。得られた結果は、下記に示す評価基準で判定し1〜5の評点を付け、表1に示した。
2: シリカの取り込み性がやや悪い(ポリマー中に混ざっていないシリカが目立つ)。
3: シリカの取り込み性は実用上問題がない(シリカがポリマー中にある程度分散しており、混ざっていないシリカが存在していない)。
4: シリカの取り込み性が良好(シリカがポリマー中に均一に近い形で分散している)。
5: シリカの取り込み性が優れる(シリカがポリマー中に完全に均一に分散している)。
得られた試験片の動的粘弾性をJIS K6394に準拠して、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の条件で、温度0℃及び60℃のtanδを測定した。得られた結果は、比較例1の値をそれぞれ100とする指数として、表1の「グリップ性能」欄に0℃のtanδを、「転がり抵抗」の欄に60℃のtanδを示した。グリップ性能の指数が大きいほど0℃のtanδが大きくグリップ性能が優れることを意味する。また、転がり抵抗の指数が小さいほど60℃のtanδが低く、タイヤに使用したときの燃費性能が優れることを意味する。
・SBR:スチレンブタジエンゴム、日本ゼオン社製Nipol 1723、ゴム成分100重量部に対しオイル分37.5重量部を含む油展品。
・変性SBR1:カルボキシル基主鎖変性SBR、スチレンブタジエンゴム(LANXESS社製Buna VSL5025−0)を原料ゴムとして、その500gを4リットルのシクロヘキサンに溶解させ、これに3−メルカプトプロピオン酸6.25gおよびジラウロイルパーオキサイド0.25gを加えて80℃で5時間反応させた。その後、バルカノックス4020(バイエル社製)2.5gを加えて溶媒を除去し、乾燥させることによりカルボキシル基主鎖変性SBR508gを調製した。得られたカルボキシル基主鎖変性SBRのカルボキシ基の含有量は0.25重量%であった。このカルボキシル基主鎖変性SBR100重量部に対しオイル分37.5重量部を添加・混合し油展することによりカルボキシル基主鎖変性SBR(変性SBR1)とした。
・変性SBR2:N−メチルピロリドン基で末端を変性したSBR、N−メチルピロリドン基の含有量が0.02重量%、日本ゼオン社製Nipol NS116
・CB:カーボンブラック、東海カーボン社製シーストKH
・シリカ:エボニックデグッサ社製ULTRASIL VN3GR、BET比表面積171m2/g
・ロジン系樹脂:ロジン変性樹脂、ハリマ化成社製ハリタックAQ−90A
・テルペン系樹脂:芳香族変性テルペン樹脂、ヤスハラケミカル社製YSレジンTO−125
・オイル:昭和シェル石油社製エキストラクト4号S
・酸化亜鉛:正同化学工業社製酸化亜鉛3種
・ステアリン酸:日油社製ビーズステアリン酸YR
・老化防止剤:フレキシス社製サントフレックス6PPD
・ワックス:大内新興化学工業社製サンノック
・カップリング剤:シランカップリング剤、エボニックデグッサ社製Si69
・硫黄:鶴見化学工業社製金華印油入微粉硫黄
・加硫促進剤:大内新興化学工業社製ノクセラーCZ−G
