FLAMEPROOF CORRUGATED CARDBOARD AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide: a flameproof corrugated cardboard having practically sufficiently high flameproof performance; and a method of manufacturing the same.SOLUTION: A flameproof corrugated cardboard 1A includes an antiflaming paper 3 obtainable by impregnating a flameproofing agent for impregnation into a cardboard. The antiflaming paper 3 is stuck to one or both surfaces of a corrugated cardboard 2 by a flameproof adhesive 4 obtainable by mixing a flameproofing agent for adhesion into adhesive. The flameproofing agent for impregnation is applied to one or both surfaces of the corrugated cardboard 2. The flameproofing agent for impregnation is mixed with a penetration accelerator to promote penetration into the cardboard.
