Abstract: PROBLEM TO BE SOLVED: To obtain a foamed heat insulation material having excellent heat insulation performances by adding a carbonate synthesis catalyst coated with a resin film and a carbonate compound prepared by reacting an epoxide compound with carbon dioxide to a resin composition having closed cells filled with a volatile blowing agent and containing at least urethane bonds and urea bonds. SOLUTION: The volatile blowing agent used is exemplified by cyclopentane. The carbonate synthesis catalyst used is one prepared by previously coating a powder of a nucleophilic compound (e.g. tetraalkylammonium halide) with a resin film (e.g. ethyl cellulose film). The epoxide compound used has a viscosity of 1,000 Pa.s or below at 25 deg.C and is exemplified by ethyl glycidyl ether. A heat insulation material 4 comprises a resin skeleton 5 comprising urethane bonds, urea bonds and a carbonate compound and closed cells containing a synthesis catalyst 7.

Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a dwelling house wall so as to improve construction efficiency and heighten heat insulating performance of the whole heat insulating panel by covering plural vacuum heat insulating materials with an urethan resin composite which has a specified closed cell rate, and in which gas in a cell of the closed cell is carbon dioxide. SOLUTION: An urethane resin composition is foamed and filled in a space part formed by a face material 4 and a frame material 6 having a longitudinal material 7 to be taken as a first layer. Subsequently, plural vacuum heat insulators 3 are arranged on the first layer of urethane resin composition, urethane resin composition for the second layer is foamed and filled, and a face material 5 is also foamed in a body to manufacture a heat insulating panel 1. A foam heat insulating material 2 takes carbon dioxide generated by interaction of isocyanate and water as a foaming agent, and the foam heat insulating material 2 formed of foamed urethane resin composition has a closed cell percentage of 40-80% by an emulsifler. As the heat insulating panel 1 jointly uses the foam heat insulating material and the vacuum heat insulating material 3, it has excellent heat insulating performance, so that the wall thickness of the heat insulating panel 1 can be reduced so as to remarkably improve construction efficiency.

Abstract: PROBLEM TO BE SOLVED: To improve heat insulation properties while taking in consideration the reduction of a burden to global environment by forming a foam heat insulating material from an expanded polyurethane resin composition having closed cell filled with a volatile compound, and containing a bubble fining agent at least inside the independent cells at partial pressure lower than the volatile compound. SOLUTION: Two components of a premixed component A in which polyole, a foaming agent, a catalyst, a reactive foaming agent, a volatile foaming agent and a bubble fining agent are previously mixed with each other, and a component B consisting of polyisocyanate, are mixed with each other and agitated by a high pressure foaming machine. Then, an ABS resin-made surface bar 2 and a steel plate-made surface bar 3 are foamed and filled in a space part formed through a flange part 4, so that a heat insulating case body 1 is molded. Here, the bubble fining agent is a volatile compound having reaction to lower the diameters of the closed cell composing the foam heat insulating agent 5 of the heat insulating case body 1. Hereby, the diameters of the bubbles of the foam heat insulating agent are fined and foam insulation properties can be improved while taking in consideration the reduction of a burden to global environment.

Abstract: PURPOSE: To obtain a foamed product which reduces the load to the global environment with excellent thermal insulation. CONSTITUTION: A thermally insulating foamed product in which the pores are substantially filled with the vapor of a volatile foaming agent and the partial pressure of the vapor is higher that 5mmHg at 25 deg.C is obtained through the mixing and foaming process whereby the polyurethane starting substances containing a reactive foaming agent, a volatile foaming agent with a molecular weight of 70 or more, boiling at 150 deg.C or lower, an epoxy compound, and a carbon dioxide-fixing catalyst are mixed and foamed to form a foamed polyurethane having closed cells containing carbon dioxide liberated by reaction of the reactive foaming agent with polyisocyanate and the volatile foaming agent, and the following process whereby the carbon dioxide adds to the epoxy groups in the epoxy compound in the presence of a carbon dioxide-fixing catalyst to form a solid or liquid cyclic carbonate.

Abstract: PURPOSE: To adsorb and remove gaseous CO2 contained in rigid urethane foam and to improve the heat insulating performance by using a gaseous CO2 adsorbent in urethane stock to be foamed integrally. CONSTITUTION: Powder of an alkali metal hydroxide or an alkaline earth metal hydroxide is mixed with a water carrying water-absorbing substance and the resultant mixture is granulated and surface-treated with an org. coating agent, etc., to obtain the objective gaseous CO2 adsorbent. This adsorbent does not adsorb water in urethane stock and can adsorb and remove only gaseous CO2 in foam after foaming.
