Description
を含んでなり、成分(A),(B)及び(D)を成分(C)の添加前の第一次混合時に混合してなるタイヤ用ゴム組成物並びにそれを用いた空気入りタイヤが提供される。
サンプルの調製
表I及び表IIに示す配合(重量部)に従って、硫黄及び加硫促進剤を除くゴム、OBSA,カーボンブラックなどの各配合成分を1.7リットルのB型バンバリーミキサーに装填して5〜6分間混合し、165℃に達したときに得られたマスターバッチに、硫黄と加硫促進剤を配合してオープンロールにて混練することでゴム組成物を得、その一部を以下の加硫速度試験に供した。次いで、残部のゴム組成物を所定の金型中で、160℃で20分間プレス加硫して試験サンプル(ゴムシート)を作製し、以下の転がり抵抗及び引張試験に供した。結果を、表I及び表IIに示す。
1)加硫速度: JIS K6300に準拠して測定した。振動式ディスク加硫試験機を用いて、振幅1度、160℃の条件下で、30%加硫度に達する時間(分)を測定した。
2)転がり抵抗性: JIS K6394に準拠して、(株)東洋精機製作所製の粘弾性スペクトロメーターを用いて、初期歪=10%、振幅=±2%、周波数=20Hzの条件下でtanδ(60℃)を測定し、この値をもって転がり抵抗性を評価した。結果は、比較例1,2,5及び7の値を100として指数で示した。この指数が小さい程、転がり抵抗性が良好であることを示す。
3)破断強度: JIS K6251に準拠して、JIS3号ダンベル状サンプルを用いて、破断時引張強さ(TB)を測定した。結果は、比較例1,2,5及び7の値を100として指数で示した。この指数が大きい程、破断強度が大きいことを示す。
4)スコーチ:JIS K6300に準拠して温度125℃にて粘度が5ムーニー単位上昇する時間を測定した。結果は比較例1,2,5及び7の値を100として指数で示した。この指数が小さい程スコーチが早く加工性が悪化することを示す。
