Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a dwelling house wall so as to improve construction efficiency and attain high heat insulation performance of a dwelling house by covering plural vacuum heat insulators with a foam synthetic resin. SOLUTION: Previously a spacer is fitted to a vacuum heat insulator 3. After the vacuum heat insulators 3 are installed in a face material with a designated space between the vacuum heat insulator 3 and the face material, a foam heat insulating material 2 is filled to cover the whole of the vacuum heat insulators 3 with a foam heat insulating material. The heat insulating panel 1 has a frame 5, and the frame 5 is partitioned by a longitudinal material 6 to heighten the rigidity of the frame 5. By jointly using the foam heat insulating material 2 and the vacuum insulators 3, the heat insulating panel 1 is forced to exhibit heat insulating performance, so that the wall thickness of the heat insulating panel 1 can be reduced so as to remarkably improve construction efficiency. As the vacuum insulators 3 are covered with the foam heat insulating material 2, external shock is not applied to the vacuum insulators 3 so as to solve the problem that the vacuum heat insulators 3 are burst by a shock at the time of construction and dew condensation is caused by deterioration of performance of the heat insulating panel 1.

Abstract: PROBLEM TO BE SOLVED: To suppress deterioration in thermal conductivity even at the time of leak, by forming an outer covering material into a baggy shape by thermally welding a laminate film, forming the heat welding layer of the outer covering material by a high density polyethylene resin, filling a plurality of core materials in the outer covering material, thermally welding the outer covering material by a part between the core material and arranging an independent vacuum part. SOLUTION: After core materials 2 formed of water bubble communication foams are heated and dried and a plurality of core materials 2 is uncontinuously filled in outer covering material 3 previously thermally welded in several parts at constant intervals in parallel with a pressure reducing direction, the outer covering material 3 are depressurized and tightly closed, so that the insides thereof become a predetermined degree of vacuum. After that, the outer covering materials 3 are thermally welded by the uncontinuous part of the core materials 2 so as to form independent vacuum parts 4, thus a vacuum heat insulating body 1 can be obtained. In the thusly obtained vacuum heat insulating body 1, the respectively independent vacuum parts 4 are formed, therefore, even though a part of the outer covering materials 3 is damaged, influence may not be exerted on the other vacuum part. Hereby, deterioration of thermal conductivity as the whole of the vacuum heat insulating body 1 is diminished. Therefore, the operation factor of a compressor may not be excess.

Abstract: PURPOSE:To prevent the deterioration of gas barrier performance and enable a large size to be applied by blow molding a material having high gas barrier quality to form a vessel of hollow compact, and internally decompressing and sealing the vessel after charged with a core material. CONSTITUTION:A parison with wall thickness distribution adjusted to a molding elongation rate with a parison controller, is blow molded, thereby forming a vessel 2 of hollow compact. The vessel 2 is filled with a core material of high insulation performance available from the pulverization of hard urethane foam or the like. Then, the vessel 2 is internally decompressed and sealed, thereby forming a vacuum insulation pack 1. In this case, the vessel 2 is constituted of an outermost layer 4 made of a layer 5 such as polypropylene resin having high chemical resistance and moldability, an intermediate layer 6 made of a layer 7 such as ethylene vinyl alcohol resin having high gas barrier quality, and an innermost layer 8 made of a layer 9 such as polypropylene resin having high chemical resistance and moldability, thereby enhancing the gas barrier quality.

Abstract: PURPOSE:To ensure process quality and provide a high performance heat insulating object, in a heat insulating object whose interior is hermetically closed under reduced pressure, by judging the quality of the open-cell foaming of rigid urethane foam used as a core material in a foaming process. CONSTITUTION:A jig 4 having a pressure sensor arranged thereto, a detector 6 detecting pressure, a display part 7 displaying pressure and a quality judging device 8 are provided and the quality of the open-cell foaming of hard urethane foam is judged from a change in the foaming pressure of the rigid urethane foam subjected to foam injection molding within the jig 4. The hard urethane foam 2 judged to be a good product is used as a core material to be covered with a metal-plastic laminated film to produce a heat insulating object whose interior is hermetically closed under reduced pressure.

Abstract: PURPOSE:To secure an excellent flowability in producing an open-cell rigid polyurethane foam even when a halogenated hydrocarbon blowing agent which exhibits a strong resin-dissolving power and has at least a hydrogen atom and a fluorine atom is used, and to produce a foam which has excellent thermal insulating properties and is used as a thermal insulator or a core of the insulator of a refrigerator. CONSTITUTION:An open-cell rigid polyurethane foam is prepd. by using a polyol component contg. at least 70wt.% polyol mixture consisting of 30-70wt.% arom. diamine-initiated polyether polyol and 70-30wt.% trimethylolpropane-initiated polyether polyol. Thus, the local degradation in the strengths of the foam due to an extreme orientation of cells is avoided, and a foam having strengths enough for a core of a thermal insulator and excellent thermal insulating properties is produced.

After the inner box 5 is fitted to an outer box 2, urethane stock, which adopts CO2 generated through the reaction of water with isocyanate as foaming agent, is poured between both the inner box 5 and the outer box 2 for filling so as to produce rigid urethane foam 4 in order to obtain a heat insulating box 6. Thus, the deterioration with time of the obtained box is small and its stable heat insulating properties can be maintained over a long period of time.
