    摘要: There are disclosed a thermal insulating foamed material, which is superior in thermal insulating property and does not cause deterioration of the thermal insulating property with a time lapse, and a method for producing the same. According to a method for producing a thermal insulating foamed material, a foamed polyurethane resin composition having closed cells, in which at least carbon dioxide is filled, is formed by blowing a raw material mixture containing epoxides comprising at least two members of an epoxide compound having high reactivity with carbon dioxide and an epoxide compound having low reactivity with carbon dioxide, a carbon dioxide fixation catalyst, polyisocyanate, a reactive blowing agent which evolves carbon dioxide by reacting with said polyisocyanate, and a polyol composition. Then, the carbon dioxide in the closed cells is allowed to react with the epoxides in the presence of the carbon dioxide fixation catalyst, thereby to fix carbon dioxide as carbonate compounds.
