Abstract: PURPOSE: To obtain a foamed insulating material which adsorbs only carbon dioxide and has heat-insulating performance improved by mixing a polyol, a polyisocyanate, a foam stabilizer, a catalyst, a carbon dioxide adsorbent coated with an organic coating agent and a foaming agent such as hydrocarbon and foaming the mixture. CONSTITUTION: A polyol such as an aromatic amine polyether polyol, an organic polyisocyanate, a foam stabilizer, a catalyst, a carbon dioxide adsorbent coated with an organic coating agent such as a methacrylate coating agent on its surface (zeolite), and a foaming agent containing at least one of hydrocarbon such as pentane or cyclopentane are admixed and heat-foamed to give this foamed insulating material, for example, an insulating box, as the carbon dioxide adsorbent adsorbs only carbon dioxide without adsorption of moisture whereby the insulating performance is improved without damage in foaming efficiency of the foam products.

Abstract: PURPOSE:To obtain the title material which does not suffer from a dispersion of density due to, e.g. the separation of a blowing agent, and has a quality equivalent to that of a heat-insulation material prepared by using a conventional halohydrocarbon as the blowing agent even when an aliphatic or cyclic hydrocarbon poorly compatible with a polyol as the raw material of a urethane resin is used as the blowing agent and contributes to the solution of the environmental problem of ozonosphere depletion. CONSTITUTION:The title material is prepared by mixing under agitation polyol component containing at least 5% polyether polyol, obtained by the addition polymerization of a diol or a triol with an alkylene oxide, with an organic polyisocyanate, a foam stabilizer, a catalyst and a blowing agent consisting of at least an aliphatic or cyclic hydrocarbon of a boiling point of 80 deg.C or below, and the heat-insulation box is prepared by packing the heat-insulation material into the space between the inner and outer boxes by in-situ foaming.

Abstract: PURPOSE:To enable a superior thermal insulating performance to be maintained for a long period of time by a method wherein a thermal insulating box comprises an outer box, a hard urethane foam containing carbon dioxide gas adsorption agent, and an inner box molded by specific high nitryl ABS resin composition. CONSTITUTION:A thermal insulating box is comprised of an outer box, a hard urethane foam containing carbon dioxide gas absorption agent and having as foam agent component 1,1-dichloro 2,2,2-trifluoroethane (HCFC-123) and an inner box molded by a high nitrile ABS resin composition got through monomer mixture of cyanide vinyl compound of 57 to 63wt.% under a presence of conjugative diene synthetic rubber of 14 to 16 weight part and aromatic vinyl compound of 37 to 43wt.%. With such an arrangement, carbonic dioxide gas contained in the hard urethane foam can be removed by carbonic dioxide gas adsorption agent and at the same time even if pressure in air bubbles is decreased, an air transmittance is low due to the fact that high nitrile ABS resin compound having a minute molecular structure is used as the inner box material. In addition, it has a high chemical resistance against HCFC-123, resulting in that no cracks are generated and no immersion of air occurs and it shows a superior thermal insulating performance in view of its aging characteristic.
