Abstract: There are disclosed a thermal insulating foamed material, which is superior in thermal insulating property and does not cause deterioration of the thermal insulating property with a time lapse, and a method for producing the same. According to a method for producing a thermal insulating foamed material, a foamed polyurethane resin composition having closed cells, in which at least carbon dioxide is filled, is formed by blowing a raw material mixture containing epoxides comprising at least two members of an epoxide compound having high reactivity with carbon dioxide and an epoxide compound having low reactivity with carbon dioxide, a carbon dioxide fixation catalyst, polyisocyanate, a reactive blowing agent which evolves carbon dioxide by reacting with said polyisocyanate, and a polyol composition. Then, the carbon dioxide in the closed cells is allowed to react with the epoxides in the presence of the carbon dioxide fixation catalyst, thereby to fix carbon dioxide as carbonate compounds.

Abstract: PROBLEM TO BE SOLVED: To improve secular heat insulating performance by depressurizing and sealing the inside of an outer member including a room temperature activation type getter material and the like. SOLUTION: As a room temperature activation type getter material to absorb and eliminate at least nitrogen, oxygen, a water content and carbon dioxide, a combo getter including barium-lithium alloy is used for a gas absorbent 5. A predetermined amount of 'Toku-seal P(R)' 4 is filled into an inner bag member 3 having permeability so as to prepare the core 2 of this vacuum heat insulating body 1. In this case, after heat treatment is executed to the core 2 at about 150 deg.C for about 1 hour, the core 2 is inserted together with the gas absorbent 5 in a gas barrier film-made outer member 6. Vacuum exhaustion is performed by a vacuum chamber equipped with a thermal seal device, and the end part of the outer member 6 is sealed by thermal seal. At this time, exhaustion and depressurization are so performed that the initial internal pressure of the vacuum heat insulating body 1 is set to less than about 13 pascals.

Abstract: PROBLEM TO BE SOLVED: To recycle the hard urethane foam, and reduce weight of a powdered vacuum heat insulating material and the scattering of the coarse particulate, by using a mixture of the urethane foam powder and a fiber material as a core material. SOLUTION: A vacuum heat insulating material 1 comprises, for example, a core material 2, a nonwoven fabric 3 having the air permeability, and a covering material 4 formed of a plastic laminate film. The core material 2 is prepared by adding the wet silica powder into the powder obtained by grinding the hard urethane foam for the surface reforming, and then adding and mixing a fiber material. Then the core material is filled in the nonwoven fabric 3 having the air permeability, and then dried, and further it is filled in the covering material, and evacuated under the reduced pressure to obtain the vacuum heat insulating material 1. In the vacuum heat insulating material manufactured as mentioned in the above, the hard urethane foam can be recycled, whereby the recycling of the heat insulating material used in a refrigerator becomes possible. Further the used paper mixed in the fiber material acts as a binder, so that the scattering of the coarse particulate can be reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain an expandable heat insulating material and a heat insulating box body having excellent heat insulating performance without worsening foaming efficiency of expandable heat insulating material by fixing carbon dioxide in the closed cells of expandable heat insulating material by a reaction. SOLUTION: This carbon dioxide fixing agent is obtained by dissolving a solid epoxide compound, a halogenated metal, an onium salt in an organic solvent and drying and removing the organic solvent. A premix component and a polyisocyanate component are integrally foamed using the carbon dioxide fixing agent or the carbon dioxide fixing agent is retained in a packing body and arranged in an inner box, or the carbon dioxide fixing agent in a rigid urethane foam is integrally formed with the inner box and impregnated. Thereby, carbon dioxide in the rigid urethane foam is efficiently absorbed and removed.
