    Abstract: PURPOSE:To prevent THE shrinkage of a foam and keep an appearance.quality for a long term by a method wherein a rigid urethane foam loaded with a cyclopentane as a component of a foaming agent and water as an adjuvant foaming agent is foamed to be loaded between an inner box made of a high- nitrile resin composition and a metallic outer box. CONSTITUTION:A graft copolymer and a coplymer are obtained by polymerizing a monomer mixture of 30-50wt.% vinyl cyanide compound and 50-70wt.% aromatic vinyl compound in the presence of a conjugated diene synthetic rubber. A high-nitrile resin composition mixed with an acrylate rubber having 2-4C alkyl is molded into an inner box 6. The inner box 6 is coated with the coplymer obtained by polymerizing a monomer mixture of 30-50wt.% vinyl cyanide compound and 50-70wt.% aromatic vinyl compound. A rigid urethane foam 5 loaded with a cyclopentane as a foaming agent and 1 part or more water as an adjuvant foaming agent is foamed to be loaded between the inner box 6 and a metallic outer box 3.

    Abstract: PURPOSE:To improve gas barrier performance and moldability, and protect the appearance from being deformed by applying the constitution where multilayer plastic for forming a vessel to cover a core material of high insulation performance is provided with at least one layer of ethylene vinyl alcohol copolymer resin layer containing a specific amount of ethylene. CONSTITUTION:A vessel 3 is made of multilayer plastic having an outermost layer 4, an intermediate layer 6 and an innermost layer 8. The outermost layer 4 is formed out of a resin layer 5 made of polypropylene resin or the like of almost 100mu thickness having high chemical resistance. The intermediate layer 6 is formed out of a resin layer 7 made of ethylene vinyl alcohol copolymer resin of almost 100mu thickness having high gas barrier performance and containing 20mol.% to 50mol.% of ethylene. The innermost layer 8 is formed out of a resin layer 9 made of polypropylene resin or the like of almost 100mu thickness having high chemical resistance and moldability. The vessel 2 is filled with a core material 3 formed via the pulverization of hard urethane foam.

    Abstract: PURPOSE:To maintain and ensure an excellent heat insulating capability for a long period of time by improving the capability of a carbon dioxide adsorbing substance of the adsorbent for a heat insulating body of which the inside is decompressed and sealed. CONSTITUTION:A heat insulating body 5 of which the inside is decompressed and sealed is provided by making a hard polyurethane foam with an open cell structure as a core, and covering an adsorbent 6 which contains at least an alumina compound with carbonic ions in the molecular structure as an adsorbing substance, by a covering material 3.

    Abstract: PURPOSE:To provide a vacuum heat insulating pack which can be manufactured industrially at low cost while being stabilized in performance by making up the pack of core material, a container covering the core material, and of a barrier member, and concurrently providing the barrier member for a part of the container. CONSTITUTION:This pack is made up of core material 2 made of hard urethane foam in a continuous bubble structure and the like, a container 4 which is made from a plastic laminate film 3 under vacuum, a barrier member 6 made from a plastic-metallic foil laminate film 5, and of a cover member 8 made from a plastic laminate film 7. The barrier member 6 is fitted on the inner surface of the container 4 by means of heat sealing and the like, the core material 2 made of hard urethane foam in a continuous bubble structure and the like, is filled therein thereafter, its inner section is decompressed, and the cover member 8 is hermetically sealed by means of heat sealing thereafter. Since the barrier member 6 having the metallic foil is partially stuck thereon as mentioned above, less thermal conduction by the metallic foil takes place.

    Abstract: PURPOSE:To improve the continuous bubble fraction of a skin part and prevent any foam scraps from occurring in getting rid of cut and removal parts by mounting a permeable face member on a jig with permeability as well, and manufacturing a continuous cell structural hard urethane foam panel as a core material in this face member. CONSTITUTION:In foaming of a hard urethane foam block 4, a sheet of paper and a nonwoven fabric or the like with permeability, as a surface member, are mounted and put into an open panel jig 5, but this jig 5 is also composed of a material with permeability such as a ceramic foaming body or the like. Subsequently, the hard urethane foam block 4 is cut into an optional size, and a hard urethane foam panel 7 with foam is made on the central part and the surface part. Then, adsorbed moisture or the like is heated and evaporated, and it is covered with a vessel 3 consisting of a metal-plastic laminate film, the inner part is decompressed and hermetically sealed, obtaining an insulated body 8. Since the panel 7 being obtained in this way is continuously bubbled to perfection even on the surface part, a large quantity of foam scraps should not be produced.
