| description | To provide a manufacturing method of a foam molding body in which generation of blister is prevented and has good appearance without deteriorating work circumstance.SOLUTION: A manufacturing method of a foam molding body includes: a step (1) melting, mixing and kneading a resin composition containing 100 pts.mass of polypropylene-based resin and 0.5-5.0 pts.mass of blowing agent generating carbon dioxide and containing no hydrogen carbonate at a temperature more than 10°C higher than the gasification temperature of the blowing agent; and a step (2) foam molding the resin composition melted, mixed and kneaded in the step (1) by ejecting to a die.SELECTED DRAWING: None
【課題】ブリスタの発生が抑制された外観良好な発泡成形体を、作業環境を悪化させることなく製造する方法を提供すること。【解決手段】本発明の発泡成形体の製造方法は、ポリプロピレン系樹脂１００質量部と、二酸化炭素を発生し、炭酸水素塩を含まない発泡剤０．５〜５．０質量部とを含む樹脂組成物を、前記発泡剤のガス発生温度より１０℃以上高い温度で溶融混錬する工程（１）と、前記工程（１）で溶融混錬した樹脂組成物を金型に射出して発泡成形する工程（２）とを含むことを特徴とする。【選択図】なし |
