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 provide equal combustion speed to a foamed heat insulating material, employing conventional horogenized hydrocarbon as a foaming agent and permit the securing of noncorrosive property against a metallic pipe arranged in the structural body even when a hydrocarbon, having flamability, is employed as the foaming agent of the foamed heat insulating material. CONSTITUTION:A space of a heat insulating structure 1, in which a metallic pipe 5 is arranged, is filled with a foamed heat insulating material produced by a method wherein a polyol constituent, containing at least 50% or more of benzilic ether type phenol resin, organic polyisocyanate, foam stabilizer, catalyst and a foaming agent having at least one constituent of hydrocarbon are mixed and foamed.

Abstract: PURPOSE:To provide desired gas barrier quality by vacuum forming a plastic film manufactured through a duplicate extrusion method to manufacture a vessel for covering a core material for use as a vacuum insulation pack having a cover material of a plastic film. CONSTITUTION:A multilayer film 3 formed via a duplicate extrusion method is vacuum formed to prepare a vessel 4. Also, a barrier material 8 made of a plastic-metal foil laminate film 7 and an adsorbing agent 9 are stacked and laid between a core material of hard urethane foam and the vessel 4. Then, a cover material 6 is formed out of a plastic-metal foil laminate film 5 and the vessel 4 is closed therewith. The multilayer film 3 has an outermost layer of a chemical resistant film, an intermediate layer of a gas barrier film and an innermost layer of a chemical resistant film. Furthermore, the innermost and outermost layers of the films 5 and 7 are also made of a chemical resistant film, and the intermediate layer thereof is made of aluminum foil or the like.

Abstract: PURPOSE:To keep initial heat insulating performance without an internal pressure rise for a long period and solve the waste material problem for foam waste material by using, as a core material, a hard urethane foam panel continuously foamed including a skin part. CONSTITUTION:A face material 6 such as a paper or nonwoven fabric having a silicon oil on the surface is put in a jig 5, a mixed raw material consisting of an organic polycyanate, a polyol, a catalyst, a foam making agent, a foaming agent, and a cell continuing agent is injected followed by foaming to provide a hard urethane foam block 4. A hard urethane foam panel obtained by cutting the hard urethane foam block 4 to an optional size is used as a core material, which is then covered with a vessel consisting of a metal-plastic laminate film, and the internal part is evacuated and sealed to manufacture a heat insulator.
