Description
前記粘弾性体を未加硫ゴムとし、前記粉体を鉄粉とし、前記粘弾性材料における鉄粉の体積分率を55〜74%とし、
前記材料を加圧下で混練りする第一工程と、このあと、引き続き、前記第一工程における圧力より低い0.3MPa以下の圧力下で混練りし粒状化する第二工程とを有することを特徴とする粘弾性材料の製造方法である。
以上の第一工程のあと、第二工程として、図6に示す通り、ラム3による加圧力を、第一工程における加圧力より低い圧力にした状態で、ロータ2だけを回転させる。粉体を含有する上記材料は低圧下もしくは非圧力下では、脆弱な特性を有するので、ロータ2を回転させるだけで塊をほぐすことができ、粉体を含有する粘弾性材料を粒状化することができる。
ここで、粘弾性材料中における鉄粉の体積分率を55〜74%とした際の第二工程における加圧力は、0〜0.3MPaとするのが好ましい。
また、工程11において、粘弾性材料に加える圧力は0.5MPaであった。なお、粘弾性材料に加える圧力はラム3の加圧力を変えて調整した。ラム3の加圧力はエア圧により制御しており、エア圧の圧力ゲージにより設定した。

Claims (2)
- 密閉式混練機を用いて粘弾性体と粉体とを少なくとも含有する材料を混練りして粘弾性材料を形成する方法において、
前記粘弾性体を未加硫ゴムとし、前記粉体を鉄粉とし、前記粘弾性材料における鉄粉の体積分率を55〜74%とし、
前記材料を加圧下で混練りする第一工程と、このあと、引き続き、前記第一工程における圧力より低い0.3MPa以下の圧力下で混練りし粒状化する第二工程とを有することを特徴とする粘弾性材料の製造方法。 - 前記第一工程において、前記材料を密閉式混練機内に投入するに際し、前記粘弾性体を投入したあと、前記粉体を複数回に分けて投入し、相前後する粉体の投入の間に、これらの材料の混練りを加圧下で行う請求項1に記載の粘弾性材料の製造方法。
