Description
式中、nは1〜3の整数、mは1〜5の整数、kは5〜9の整数である。
バンバリーミキサーを使用し、下記表1に示す配合に従い、ゴム組成物を調製した。その際、ゴム組成物の混合温度は160℃とした。表1の各成分の詳細は以下の通りである。
・SBR2:JSR社製「SBR1502」(スチレン含有量=24重量%、ガラス転移点Tg=−66℃、重量平均分子量Mw=約60万である乳化重合SBR)、
・天然ゴム:RSS#3。
・シリカ2:次の方法により調製したBET比表面積=240m2/g、CTAB比表面積=190m2/gのシリカを用いた。すなわち、(1)70〜85℃の範囲の温度のケイ酸塩を充填してある反応容器に、前記ケイ酸塩の全量を中和するのに要する濃硫酸の20〜50%に相当する量の鉱酸を20分以内に添加し、(2)上記(1)で得られる反応混合物を加熱して温度を90〜100℃とし、この温度を維持したまま、全濃硫酸量の80〜50%に相当する量の濃硫酸を、反応混合物のpHが7〜10の範囲になるまで、少なくとも4回に分けて添加し、その際、各濃硫酸の添加後は10〜40分間熟成し、(3)温度を90〜100℃に維持して30〜120分間、反応混合物を熟成し、鉱酸を添加してpH5以下に酸性化して反応を終了させ、得られた沈殿スラリーを濾過、水洗、乾燥してシリカを製造する。上記(1)の中和反応で使用する濃硫酸の量を全濃硫酸量の20〜50%の範囲内で多くし、また、反応混合物中のシリカ濃度を50〜80g/Lの範囲内で低くすることにより、最終的に得られるシリカのBET比表面積が大きくなるので、これらを調整することで上記BET比表面積及びCTAB比表面積のシリカが得られた。
・カーボンブラック:ISAF、三菱化学社製「ダイヤブラックN234」。
・汎用カップリング剤:ビス−(3−トリエトキシシリルプロピル)ジスルフィド、デグサ社製「Si−75」、
・オイル:ジャパンエナジー社製アロマ系プロセス油「JOMOプロセスX−140」。
