material of a complex function for reflection and heat insulation with a hollow structure

摘要

The present invention is not only high in heat insulation or heat insulation (coldness) due to high reflection effect of heat to light, but also strong in durability, heat resistance, moisture resistance, cold resistance, shock resistance, soundproof, waterproof, etc. In order to provide the hollow composite reflective reflective thermal insulation of the aluminum foil 20, the polyester film 10 is bonded to one side so as not to corrode, the nonwoven fabric 30 is bonded to one side to the other side of the aluminum foil 10 In the composite functional reflective thermal insulating material comprising a polyethylene foam (70) bonded to the other surface of the nonwoven fabric 30, the polyethylene foam (70), one surface on the other surface of the nonwoven fabric (30) The second polyethylene foam 71 and the second polyethylene foam 72 in which one surface is joined to the other surface of the first polyethylene foam 71 and a plurality of through holes 75 are formed, are joined. Other days of) The joined to 3 characterized by consisting of a polyethylene foam (73).;Insulation, Heat Insulation, Heat Insulation, Sound Insulation, Cheap, Lightweight, Hollow
