  • Patent number: 6355700
    Abstract: An insulated structure is formed by injection of a foamed thermal-insulating material created by foaming into a space between a plastic board and metal plate with a disposition of copper pipes. A non-halogenated organophosphorus compound having a molecular weight over 150 as an additive with an OH group as a functional group is mixed with the raw materials of the foamed thermal-insulating material including polyol, a foam stabilizer, a catalyst, a foaming agent having at least one component of hydrocarbon, and an organic polyisocyanates. By adding a non-halogenated organophosphorus compound, which has a molecular weight over 150 as an additive with an OH group as a functional group, the burning rate of the foamed thermal-insulating material becomes the same as that of the foamed thermal-insulating material which uses CFC11 as a foaming agent.

  • Patent number: 5773482
    Abstract: 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.

  • Patent number: 5109032
    Abstract: This invention relates to a foamed heat insulation material for refrigerators and freezers which makes it possible to reduce the quantity of a fluorocarbon foaming agent used therein. Said foamed heat insulation material is obtained by mixing a carbon dioxide adsorbent prepared by treating the surface of the carbon dioxide absorbent so as to make it hydrophobic with a water-containing premix component and an isocyanate component and stirring the resulting mixture.The foamed heat insulation material thus obtained can reduce the quantity of the fluorocarbon foaming agent at the time of foaming owing to the use of water as a foaming agent, and after the foaming, can adsorb off with the carbon dioxide adsorbent the carbon dioxide generated by the isocyanate-water reaction and thereby purify the gas in foams into a fluorocarbon gas.
