Abstract: Vacuum heat insulator comprising a laminated core made of a plurality of sheets of inorganic fibers having 10 mu m or smaller in diameter and a certain composition including SiO2 as a main component, Al2O3, CaO, and MgO, a gas barrier enveloping member, and an absorbent. The vacuum heat insulator is characterized by having at least one groove formed therein after fabrication of the vacuum heat insulator. Further, the vacuum heat insulator is characterized by using inorganic fiber core of which a peak of distribution in fiber diameter lies between 1 mu m or smaller and 0.1 mu m or larger, and not containing binding material for binding the fiber material. Electronic apparatuses of the present invention use the vacuum heat insulator. With use of the vacuum heat insulator, electronic and electric apparatuses superior in energy saving and not to present uncomfortable feeling to the user can be provided.

Abstract: The present invention provides a thermal insulating foamed material with excellent thermal insulating properties and a method of manufacturing the same. The method comprises the steps of: concurrently mixing and blowing a polyurethane material to produce a foamed polyurethane resin composition with a multiplicity of closed cells, the polyurethane material including a reactive blowing agent, a volatile compound having a boiling point of not higher than 150 DEG C and a molecular weight of not less than 70, an epoxy compound, and a carbon dioxide fixation catalyst, wherein the closed cells are filled with the volatile compound and carbon dioxide produced by a reaction of the reactive blowing agent with a polyisocyanate; and allowing the carbon dioxide to chemically react with epoxy groups of the epoxy compound in the presence of the carbon dioxide fixation catalyst to form a solid or liquid cyclic carbonate. The method gives a foamed material with the closed cells substantially filled with vapor of the volatile compound at a partial pressure of at least 5 mmHg at 25 DEG C.

Abstract: An insulated structure is produced by mixing a starting material of a foamed thermal insulating material comprising a polyol, a foam stabilizer, a blowing agent containing at least a hydrocarbon as one component, and an organic polyisocyanate with a halogen-free hydroxylated organophosphorus compound having a molecular weight of at least 150 as an additive, foaming the resultant mixture into a foamed thermal insulating material (4), and cast molding the material (4) in the space between a plastic facing (2) and an iron plate (3) provided with a copper pipe (5). The use of the above-specified organophosphorus compound serves to achieve a burning velocity equivalent to that attained by the use of the conventional blowing agent CFC11, to exclude the possibility of the corrosion of the pipe (5) in the structure caused by the dissociation of the phosphorus compound, to prevent the phosphorus from migrating into the facing (2), and to get rid of the fear of food staining.
