Abstract
Description
−ジアクリル酸亜鉛およびメタクリル酸亜鉛、ならびにこれらの混合物から成る群より選択される金属助剤
−有機ペルオキシド
−硫黄
−ハイドロタルサイト化合物
を含有するゴム用硬化性組成物が提供される。
−本発明の第二の態様に記載されている未硬化ゴム組成物を準備すること
−未硬化ゴム組成物を熱処理すること
を含む、硬化ゴムの製造方法が提供される。
ゴム組成物を以下のように製造した。
効率的な硫黄硬化系であるK4890を比較例1として用いた。
従来の硫黄硬化系であるAS2831を比較例2として用いた。
31449に類似しているが硫黄は有しないML3792−1。
硬化ゴム(1)31449、(2)K4890および(3)AS2831について、121℃の熱風およびIRM903の油において、引張および伸びの変化を経時的に測定した。熱風およびIRM903のどちらについても、31449の試料は、K4890およびAS2831に比べて、引張および伸びにおける低下がより少なかった。ASTM D573(ゴムの標準試験法−エアーオーブン内での劣化)およびASTM D471(ゴム特性の標準試験法−液体の効果)により、試験を実施した。図4〜7を参照されたい。図4および5は、熱風における121℃での硬化ゴムコンパウンドの引張および伸びの変化を示し、図6〜7は、IRM903の油における121℃での硬化ゴムコンパウンドの引張および伸びの変化を示す。
硬化ゴム(1)31449、(2)K4890および(3)AS2831について、100℃で、ASTM D395(ゴム特性の標準試験法−圧縮永久ひずみ)により、圧縮永久ひずみを経時的に測定した。31449の試料は、より少ないひずみを示した。図8を参照されたい。
真鍮被覆されたスチールワイヤに対するゴムの接着性の比較を、硬化ゴム(1)31449および(2)ML3792−1について、ASTM D1871(タイヤビードワイヤとゴムとの接着の標準試験法)により実施した。31449の接着性は、87lbfというはるかに高い接着性を示し、その一方でML3792−1は7.9lbfであった。
