BREATHABLE REFLECTIVE INSULATION MATERIALS WITH INCOMBUSTIBILITY

摘要

PURPOSE: A water permeable and waterproofing properties heat reflecting insulation material including excellent incombustibility is provided to lengthen a life by preventing decomposition and corrosion. CONSTITUTION: A water permeable and waterproofing properties heat reflecting insulation material including excellent incombustibility comprises a lower heat reflecting layer, a water permeable and waterproofing film (4), and an upper heat reflecting layer. The lower heat reflecting layer is attached to one surface of an inorganic fiber system insulation material (1) by spraying a hot-melt adhesive (2). The water permeable and waterproofing film is attached to the other surface of the inorganic fiber system insulation material by spraying the hot-melt adhesive. The upper heat reflecting layer is attached to the surface of the water permeable and waterproofing film by spraying the hot-melt adhesive. Fine pores including the pore diameters of 50-1000 μm are formed as 30-100 pores/cm^2. The lower heat reflecting layer including the pore diameters of 50-1000 μm is formed as 10-50 pores/cm^2.
