MANUFACTURING METHOD OF HEAT INSULATING AND FLAME RETARDANT BUILDING SHEET AND THE HEAT INSULATING AND FLAME RETARDANT BUILDING SHEET

摘要

The present invention is a thermal insulating and flame-retardant sheets, and in particular, heat-insulating property and flame retardancy is excellent, and deformation and unbroken architectural insulation and flame resistance sheet (1) relates to a method of manufacturing the same that are used as piping, ventilation holes and building interior and exterior materials.; The present invention includes a first laminating step (S100) of forming the first sheet (11) laminated to the aluminum film (3) in the lower portion of the PET film (2) and; A first laminating step (S100) the first sheet 11, a pressure roller pressing the drying step (S200) to (6) to supply pressure and supplying it to the heat in a dry (7) dry heat to the formed through and;; A second laminating step of laminating the net shape of the glass fiber yarn (4) a pressure-drying step (S200) to the aluminum film 3, the lower portion of the coarse first sheet 11 forming the second sheet (12) (S300) and; Second third laminating step of laminating the laminating step (S300) of the second sheet 12 of glass fiber yarns (4) of foam rubber sheet 5 in the lower portion of the manufactured through forming a heat-insulating and flame retardant sheet 1 ( S400), and;; The third lamination step (S400) for the insulation and flame retardant sheet 1, the pressing roller 6 is supplied to the pressure-drying step (S500) for pressing and supplying it to the heat by drying (7) Dry heat as prepared in the .; It made a pressurized drying process (S500) and the rough-retardant insulation sheet (1) to the cooling step (S600) for cooling the cooling unit (9).
