Abstract: A foamed heat-insulating material for cold storage and refrigerator, wherein the amount of a fluorocarbon blowing agent is reduced, which is prepared by stirring a mixture of a carbon dioxide adsorbent having a hydrophobic surface with a water-containing premix component and an isocyanate component. The amount of a fluorocarbon blowing agent can be reduced by using water as the blowing agent. Carbon dioxide generated by the reaction of water with the isocyanate is removed by adsorption with the carbon dioxide adsorbent after the foaming to thereby obtain purified fluorocarbon gas from gases enclosed in the cells.

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.

Abstract: An insulation box unit and a refrigerator of the present invention employs i) rigid urethane foam with a 8.0 MPa-or-greater bending modulus, and a 60 kg/m 3 -or-lower density, and ii) a vacuum insulation material. The proper bending modulus provides the insulation box unit with a substantial strength, even in the case that the coverage of the vacuum insulation material with respect to the surface of the outer box exceeds 40%. The proper density prevents the insulation box unit from poor insulation efficiency due to undesired solid thermal conductivity. Despite of an extended use of the vacuum insulation material, the insulation box unit offers an excellent insulation efficiency and therefore accelerates energy saving. According to the recycling method of the present invention, rigid urethane foam formed of tolylene di-isocyanate composition, which was separated from refrigerator wastes, is recycled as a material of rigid urethane foam.

Abstract: The insulated structure is formed into the space between the plastic board (2) and metal plate (3) with a disposition of copper pipes (5) by injection of the foamed thermal-insulating material being created by foaming (4), wherein a non-halogenated organophosphorus compound having a molecular weight over 150 as an additive with an OH group as a functional group is mixed with the raw materials of the foamed thermal-insulating material being comprised of polyol, a foam stabilizer, a catalyst, a foaming agent having at least one component of hydrocarbon, and an organic polyisocyanates.
By adding a non-halogenated organophosphorus compound which has a molecular weight over 150 as an additive with an OH group as a functional group, the burning rate becomes the same as that of the present CFC11 foaming agent; in addition, the possibilities of phosphor corrosion by free ionization to the copper pipes (5) which are disposed inside of the insulated structure are eliminated and phosphorus transfer to the plastic board (2) and worries of food contamination are also eliminated.
