Abstract

金型をゆっくり回転しながら加熱して、プラスチック粉末を溶かして金型内面に表皮を作り、その上に粒状体を付着させ、更に加熱して粒状体に含まれる架橋剤を分解して架橋ポリオレフィンにし、その中で発泡剤を分解させて低密度の架橋ポリオレフィン発泡粒状体にし、この粒状体を金型内に充満させて金型中央に集まった空気をチューブで金型外に排出し、このチューブに溶融した発泡粒状体を入れて詰まらせてシールし、金型内の温度を２００℃以上にし、架橋ポリオレフィン発泡粒状体を合体させてコアにし、表皮とコアとを接合し、冷却して全面に表面材があり、その中に密度が０．２ｇ／ｃｃ以下のコアがあり、見掛け密度が０．０４～０．５ｇ／ｃｃ、曲げ強度が３．８ＭＰａ以上、せん断強度が０．０２ＭＰａ以上、かつ圧縮強度が０．７ＭＰａ以上の表皮と架橋ポリオレフィン発泡粒状体を合体させてなるコアとを有するプラスチックサンドイッチ構造体の一工程での製造方法。
