Abstract: A foamed heat-insulating material for cold storage and refrigerator, wherein the amount of a fluorocarbon blowing agent is reduced, which is prepared by stirring a mixture of a carbon dioxide adsorbent having a hydrophobic surface with a water-containing premix component and an isocyanate component. The amount of a fluorocarbon blowing agent can be reduced by using water as the blowing agent. Carbon dioxide generated by the reaction of water with the isocyanate is removed by adsorption with the carbon dioxide adsorbent after the foaming to thereby obtain purified fluorocarbon gas from gases enclosed in the cells.
