Abstract
【解決手段】少なくともゴム成分と、充填剤と、アミノ基を含んだチオ硫酸化合物とを混合する(A)工程と、この(A)工程により得られた混合物と、硫黄成分と、加硫促進剤とを混合する(B)工程とを有するタイヤ部材の製造方法において、(A)工程において、アミノ基を含んだチオ硫酸化合物をゴム成分100質量部に対して0.2質量部以上配合し、かつ(A)工程において混合中の混合物の温度を145〜170℃の範囲内に20秒間以上保持する。

Description
反応容器を窒素置換し、反応容器中に、3−ブロモプロピルアミン臭素酸塩25g(0.11mol)、チオ硫酸ナトリウム・5水和物28.42g(0.11mol)、メタノール125ml及び水125mlを仕込み、得られた混合物を70℃で4.5時間還流した。
攪拌機、温度計、冷却機を備えた500mlの四つ口フラスコに、フタルイミドカリウム49.6g(0.27mol)及びジメチルホルムアミド240mlを仕込み、得られた混合物に、1,6−ジブロモヘキサン100g(0.41mol)とジメチルホルムアミド100mlとの混合物を室温で滴下した。滴下終了後、得られた混合物を120℃まで昇温し、4時間還流させた。反応終了後、反応混合物から溶媒を留去した。そこに、酢酸エチルと水とを加えて分液した後、有機層を濃縮した。得られた残渣にヘキサンと酢酸エチルとを加え、得られた混合物を静置したところ、結晶が析出した。結晶をろ取し、真空乾燥して、N−(6−ブロモヘキシル)フタルイミドを56.5g得た。
表1〜3に示した配合に従い、各成分を表の混合(A)工程に示した条件でバンバリーミキサーを用いて混合し、次いで混合(B)工程で示した加硫促進剤と硫黄を添加混合したのち、150℃にて30分間加熱することにより加硫を行い、タイヤトレッド部材を得た。
