Abstract
A composite heat-insulating material and a process for the production thereof are described. This material is of the structure that an olefin-or styrene-based resin sheet and a urethane foam material are laminated on each other with an adhesive containing: (A) 20 to 100% by weight of a water-soluble polyimine compound selected from the group consisting of polyethyleneimine, poly(ethyleneimine-urea), and a polyaminepolyamide/ethyleneimine adduct, and (B) 80 to 0% by weight of a nitrogen atom-containing cationic or amphoteric polymer. This composite heat-insulating material is very suitable for use as a lining material for a refrigerator, for example.
