Abstract: PURPOSE:To produce a heat insulation wall with decreased thermal conductivity and improved heat insulation properties, by foaming a foamable heat insulation material comprising a specific benzylic ether-type liq. phenolic resin compsn. integrally with a surfacing material comprising an ABS resin. CONSTITUTION:A heat insulation wall is produced by foaming a foamable heat insulation material comprising a mixture of a benzylic ether-type liq. phenolic resin compsn., 10-15wt.% (based on the resin compsn.) polyethers prepd. using a non-amine active hydrogen compound as the initiator, a catalyst, a cell stabilizer and an org. polyisocyanate, integrally with a surfacing material comprising an ABS resin. The foamable heat insulation material adheres very well to and chemically attacks slightly the surfacing material during the integral foaming, and does not cause whitening, cracks and delamination in the surfacing material even after a long-time use, thus enabling a significant quality improvement.

Abstract: PURPOSE:To prepare a foam having fine voids, by using a resin prepared by mixing specific amt. of a benzyl ether type phenol and a low viscous polyol as a foamable base material. CONSTITUTION:5-20wt.% a low viscosity polyol (ethylene oxide adduct of a polyhydric alcohol having primary hydroxyl groups) are added to 80-95wt.% benzyl ether type phenol resin and moreover, a foaming agent, an organic polyisocyanate, a catalyst and a foam stabilizer are added to these resins. This foaming raw material is mixed in a foaming machine 8 and poured from a pouring inlet 6 toward a frange 5. As 5-20wt.% of low viscosity polyol and used together, the raw material rapidly flows in the frange 5 after pouring, and is uniformly spread and foamed to obtain a heat insulating box 1 having a low density and finely foamed heat insulating material 4'.

Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable high performance vacuum thermal insulation material insusceptible to conducting heat leak in which deformed shape can be attained by a facing exhibiting extremely excellent gas barrier properties. SOLUTION: A facing having a core material, a diamond-like carbon thin film, and a thermoplastic resin film formed on the opposite sides while covering the upper and lower surfaces of the core material is disposed in a pressure reducing tank and the core material is fused by hot press at the circumferential fringe position thus producing a vacuum thermal insulation material.

Abstract: PURPOSE: To improve foaming heat insulating performance by integrating a carbon dioxide adsorbent being foamed into a hard urethane foam to remove carbon dioxide in the hard urethane foam by adsorption. CONSTITUTION: In a carbon dioxide adsorbent 1, calcium hydroxide is impregnated with a 0.01mol. equivalence of moisture per the calcium hydroxide and a vinyl acetate resin is formed as film by a wet type spray coating. A premixing component and an isocyanate component are mixed and stirred up using a high pressure foaming machine with a specified number of blending parts and injected into a box body hollow part 5 made up of an inner box 3 and an outer box 4 from a delivery head 2 through an injection port 6. The carbon dioxide adsorbent 1 is arranged previously at a box body flange part 7 below the injection port 6 and material delivered from the delivery head 2 entrains the carbon dioxide adsorbent 1 to fill the box body hollow part 5 being mixing integral. The urethane foam 7 filled is hardened with the passage of time to obtain a heat insulating box body.

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 increase the viscous flow in a laminate layer so as to remove gas molecules in core members, and to obtain a desired vacuum degree in a short time, by laminating the core members vertically to the heat transmitting direction, in a vacuum adiabator in which core members consisting of a foaming plastics with a continuous foamy structure are filled in an outerjacketing member. CONSTITUTION: In a vacuum adiabator 1, core members 2 which consist of a foaming plastics having a contineous foamy structure are filled in an outerjacketing member 3. In this case, the core members 2 are laminated vertically to the heat transmitting direction. And between the laminated core members 2, metal layers having the thickness 500×10-5μm to 1000×10-5μm may be provided. Furthermore, when the vacuum adiabator 1 is manufactured, a process to leave a part of the core members 2, and to cut it vertically to the heat transmitting direction is provided, at least as a manufacture process of the core members 2. Consequently, a viscous flow in the laminate layer is increased, and gas molecules in the core members are removed by this viscous force, and a desired vacuum degree is obtained in a short time.
