The Influence of Fillers on the Decrease of Zinc Oxide in the Vulcanization Process

Masaru Hasegawa; Shozo Tada; Kayoko Amita; Genzo Hashizume

イオウ-TMTD 加硫における酸化亜鉛の役割を明確にする目的で加硫時間変化に対する酸化亜鉛の減少量を充てん剤存在下, 不在下でX線回折法を用いて検討した。酸化亜鉛の減少量とそれの反応生成物の定量からゴムと結合した亜鉛の存在を確認した。微粒子ケイ酸とクレーは加硫 (熱処理) により酸化亜鉛と反応することが解った。酸化亜鉛の反応生成物としてはジメチルジチオカルバミン酸亜鉛硫化亜鉛以外の含イオウ有機亜鉛化合物が存在し, これを加硫反応の活性種と考えた。この活性種の量は充てん剤の種類により変化することを認めゴムの補強性との関連性を検討した。
