Abstract
【解決手段】板状体10の押出成型に使用される押出成型用口金Aに関する。前記板状体10の厚み方向に温度差を形成するために、少なくとも一部が厚み方向に温度差が形成されるように温度調節手段5を備えて成る。
【選択図】図1
Description
・セメント(30質量部)
・骨材(62質量部)
・ポリプロピレン繊維(2質量部)
・オレイン酸系乳化剤(1質量部)
・スチレンモノマー(5質量部)
・t-ヘキシルパーオキシー2−エチルヘキサノエート(0.1質量部)
・トリメチロールプロパントリメタクリレート(0.05質量部)
また、押出成型用口金Aとしては、図1に示すものと同様の押出成型用口金Aを使用した。そして、押出成型用口金Aの上部の温度調節手段5により、板状体10の上面は冷却されるようにし、下部の温度調節手段5により、板状体10の下面は加熱されるようにした。具体的には、ジャケット体3の上面(上型部材11の上面)の表面温度は7℃、ジャケット体3の下面(下型部材21の下面)の表面温度は35℃であった。
