Method of manufacturing the Gypsum board having air cap

The present invention， unlike the conventional air cap using a specific material of the thermal insulation and soundproofing effect is not only positively improved， but also added a flame retardant material made of a high molecular compound is given an excellent level of flame retardant function， further extracted from a predetermined grain shell The use of natural synthetic resins and eco-friendly adhesives significantly reduces the amount of contaminants generated during incineration or disposal， and thus relates to a method of manufacturing functional building interior materials with eco-friendly air caps that exhibits environmentally friendly benefits. Insulating material molding step for forming the individual space of the predetermined pattern (S100); and 80 to 90% by weight of polyethylene， 5 to 10% by weight of flame retardant materials， 5-10% by weight of the natural synthetic resin obtained by melt molding Air cap molding step (S200) to be several air balls are alternately arranged in the individual space of the insulation material; Applying the natural adhesive to both surfaces of the air cap and the heat insulating material bonding step (S300) which is integrated with the insulating material; characterized in that the composed.
