A method for manufacturing a composite functional insulation material improved in fire resistance and heat insulation and a composite functional insulation material produced by the method

摘要

The present invention relates to a method of manufacturing a composite functional insulating material, and to a composite functional insulating material manufactured by the method, and more particularly, a method of manufacturing a composite functional insulating material having improved fire resistance and heat insulation by having a structure in which a plurality of insulating material layers are stacked, and the same It relates to a composite functional insulating material manufactured by the method. The method of manufacturing a composite functional insulating material with improved fire resistance and heat insulation, according to the present invention, forms a base material that forms an extruded polystyrene board base material 100 by fusing aluminum foil (A) on the front and rear surfaces of the extruded polystyrene board 110 Step (S1); A unit thermal insulation sheet forming step (S2) of forming a unit thermal insulation sheet 200 by fusing an aluminum foil (A) on one surface of the foamed polyethylene mesh resin 210; The adhesive is applied in a lattice pattern on one side of the aluminum foil (A) and heat-sealed facing the other aluminum foil (A) to form an air pocket sheet 300 in which an air pocket 310 is formed in the center of the lattice pattern adhesive portion. Air pocket sheet forming step (S3) and; A flame-retardant sheet forming step (S4) of forming a flame-retardant sheet 400 by fusing aluminum foil (A) on the front and rear surfaces of any one of glass fiber, silica gel, or aerogel, which is a semi-non-flammable material; The fireproof and heat insulating properties of the present invention integrated by heat-sealing the unit thermal insulation sheet 200, the air pocket sheet 300, and the flame-retardant sheet 400 sequentially on the upper surface of the extruded foamed polystyrene board base material 100 It characterized in that it comprises a; fusion bonding step (S5) to form an improved composite functional insulation. According to the present invention made as described above, it is possible to prevent human damage from fire by preventing the propagation of flames in the event of a fire, thereby ensuring sufficient fire evacuation time for occupants, and maintaining the indoor temperature at a comfortable temperature for the human body. By removing the cause of condensation that may occur on the inner wall, the occurrence of diseases from moisture and mold can be prevented, noise can be prevented and vibration attenuated between generations, and infiltration and moisture permeation can be prevented. A method of manufacturing a composite functional insulating material with improved fire resistance and heat insulation that can be expected to have a high heat insulating effect with a small volume and easy surface finish, and a composite functional insulating material manufactured by the method are provided.
