Thermal insulating foamed material having carbon dioxide adsorbents and method for manufacturing the same |
摘要 |
<p>A thermal insulating foamed material is a polyurethane foam having closed cells, and produced by mixing, agitating and foaming a polyol, a polyisocyanate, a foam stabilizer, a catalyst, a blowing agent and a carbon dioxide adsorbent. The carbon dioxide adsorbent is produced by mixing and granulating powders of at least one member of alkali metal hydroxides and alkaline-earth metal hydroxides and organic or inorganic powders having a water absorbing property and soaked with water in advance, and formed by a resin film, such as a methacrylic acid ester, which is permeable to carbon dioxide but hardly permeable to water.</p> |
