PURPOSE: A manufacturing method of incombustible interior and exterior materials by using corrugated cardboard is provided to increase the productivity by reducing manufacturing hours with infiltrating resin solution into the corrugated cardboard quickly and evenly, and to prevent fire and improve the rigidity by adding incombustible material to resin solution and stacking corrugated cardboard layers. CONSTITUTION: Incombustible material of 5-10% is added to thermosetting resin solution, and the corrugated cardboard is immersed in the mixed thermosetting resin solution for 10-20 minutes. The corrugated cardboard immersed in the resin solution is dried at 60-120 deg.C for 7-15 minutes. Interior and exterior materials(1) are manufactured by stacking one or more sheets of corrugated cardboard and pressing at 100-150 deg.C for 5-10 minutes in drying the corrugated cardboard immersed in the resin solution at 70-80%. The productivity is increased by reducing infiltration time with infiltrating the resin solution into the corrugated cardboard promptly. The rigidity is improved by stacking and pressing sheets of corrugated cardboard before hardening resin solution completely, and fire is prevented by adding the incombustible material to the resin solution.
