Abstract

PURPOSE: To increase the adsorption rate of CO2 gas remaining in hard urethane foams to improve the heat insulation by setting a vacuum package formed by covering a CO2 gas absorbent with a plastic film capable of being dissolved in or swollen with a fluorocarbon type foaming agent between an inner and outer boxes and forming a box by implementing monolithic foaming with a hard urethane foam. CONSTITUTION: An outer cover 9 of a package 7 formed by vacuum-packaging synthetic zeolite CO2 adsorbent 8 as a carbon dioxide gas adsorbent is a biaxially oriented polystyrene film The package 7 is fixed to the back of an inner box 3 with adhesive tape, etc., and monolithic foaming is carried out with hard urethane foam using fluorocarbon 11 as a foaming agent between the inner and outer boxes 2 to form a heat-insulated box 1. Carbon dioxide gas in the hard urethane foam 4 reaches the CO2 adsorbent 8 filled in the package 7 held at a negative pressure via cracks/pin-holes produced in the cover 9 after being subjected chemical attack of the contained foaming agent. Esp. because the adsorbent 8 is vacuum-packed, provide adsorption rate of CO2 gas is very high and because of the CO2 gas adsorption a gas having a high thermal conductivity such as air is never discharged instead.
