Abstract
【解決手段】非加硫性ゴムを混練する工程と、この非加硫性ゴムを押出機1により連続混錬する工程と、を有するタイヤ成形方法であって、押出機1による工程は、加硫系薬品を供給し、加硫性ゴムを連続混練する工程と、加硫性ゴムを熟成する工程と、熟成された加硫性ゴムを所定の断面形状のタイヤ部材として連続押し出し成形する工程と、を有することを特徴とする。
【選択図】図2
Description
非加硫性ゴムを混練する工程と、
この非加硫性ゴムを押出機により連続混錬する工程と、を有するタイヤ成形方法であって、
前記押出機による工程は、
加硫系薬品を供給し、加硫性ゴムを連続混練する工程と、
前記加硫性ゴムを熟成する工程と、
熟成された加硫性ゴムを所定の断面形状のタイヤ部材として連続押し出し成形する工程と、を有することを特徴とするものである。
図1において、押出機1は、スクリュー10を有し駆動装置11により駆動される。スクリュー10が収容されるバレル12には、ホッパー13が設けられており、薬品供給機14から加硫系薬品とノンプロゴムが投入される。ここで、ノンプロゴムとは、非加硫性ゴムのことであり、ノンプロゴム自体は、例えば、バンバリーミキサーにより混練される。得られたノンプロゴムは所定断面形状のシート状に形成される。
本発明に係る成形方法において、従来技術のように熟成工程を省略できるのは、押出機1の内部で熟成を行うことができるからである。そこで、熟成を行う理由の1つである「加硫性ゴム中の加硫系薬品(配合剤)の均一分散性の向上」が可能な理由は、次の通りである。
図3は、第2実施形態に係るタイヤ成形方法を行うための設備を示す図である。第1実施形態と異なる点は、成形ドラムに直接ゴムを貼り付けていく設備である。具体的には、金型16から、帯状のストリップゴムを押し出し成形し、直接成形ドラムに貼り付ける。
