Description
請求項2の発明は、請求項1に記載されたゴム混練方法において、前記不活性ガスは、窒素または二酸化炭素であることを特徴とする。
まず、原材料ゴム及びカーボンブラックや硫黄等の添加剤や配合薬品等の材料(以下、これらを総称して被混練物という)を混練するゴム混練機について説明する。図1は、本実施形態におけるゴム混練機の要部概略断面図を示す。なお、本実施形態では、上記した従来の密閉式混練機と同様に、密閉された混練室で混練を行う密閉式ゴム混練機を例に採って説明するが、粉末状の被混練物を混練するニーダーミキサー等のその他のゴム混練機にも適用することができる。
この密閉式ゴム混練機1を用いて上記した方法で被混練物Gの混練を行い、密閉式ゴム混練機1内の酸素濃度を測定した。なお、被混練物Gは、通常のタイヤ等のゴム製品の原材料であり、原材料ゴムの他に、カーボンブラックや発火しやすい硫黄粉末等の各種添加剤や配合薬品等からなる。また、被混練物G投入前の不活性ガスの導入は、機体内の酸素濃度が8体積%以下になるまで行った。
Claims (2)
