Abstract
PURPOSE: To manufacture a building board filled with a foamed material, by pouring and hardening a non-foamable resin into a part of the cavity of a frame composed of a thermoplastic resin, pouring a foamable resin to the rest part of the cavity, and foaming the foamable resin between a pair of conveyor belts, thereby preventing the deformation of the frame.
CONSTITUTION: A process for the manufacture of a heat insulating building board by filling a foamed material in a cavity of a frame 15 composed of a thermoplastic resin, characterized in that the walls of said frame are thickened and reinforced with a non-foamable resin composition 17 (e.g. vinyl chloride resin, polyethylene resin, ABS resin, etc.) before pouring said foamable resin composition 18 into said cavity, The foamable composition 18 in the frame 15 is pressed with a pair of conveyor belts 7, 7, and foamed. By thickning the walls of the frame, the catch of nails or screws can be improved
