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.

Abstract: A method of producing an open cell rigid polyurethane foam which comprises reacting a polyol with a polymethylene polyphenyl polyisocyanate prepolymer with a monool exemplified by diethylene glycol monomethyl ether by use of a substitute such as 1,1-dichloro-1-fluoroethane or methylene chloride as a volatile blowing agent, or a mixture of the volatile blowing agent with water, for trichlorofluoromethane as a blowing agent in the presence of a catalyst, a foam stabilizer and a cell opening agent. The resultant open cell rigid polyurethane foam has a cell size of about 200-250 microns, and is suitable for use, for example, as a core material in a vacuum heat insulating material. The foam may be enclosed in a container under a vacuum of 0.1-0.01 mmHg readily attainable to provide a vacuum heat insulating material of a high heat insulating performance.

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.
