HEAT REFLECTIVE SOUNDPROOF INSULATOR FOR FORMING AN AIR POCKET IN BETWEEN A BASE SHEET AND A REFLECTIVE SHEET

摘要

PURPOSE: A heat reflective soundproof insulator is provided to facilitate to join a foaming resin and a base sheet and improve the soundproof and dustproof performance through a resonance by an air pocket of a reflective sheet.;CONSTITUTION: A heat reflective soundproof insulator comprises a plate-shaped foaming resin(3), a basic sheet(4), and a reflective sheet(1). Both sides of the plate-shaped foaming resin are melted with the base sheet. The reflective sheet is joined to the surface of the base sheet. The reflective sheet is formed with an air pocket forming protrusion part(2). An air pocket(7) is formed in between the protrusion part and the base sheet surface. The reflective sheet is made of aluminum foil. The basic sheet is made from one of aluminum foil, an aluminized film, and an aluminized sheet.;COPYRIGHT KIPO 2013
