A HEAT-INSULATING AND SOUND ABSORBING MATERIAL FOR THE HEAT INSULATING AND SOUND ABSORBING STRUCTURE OF A CAR BODY |
摘要 |
[SUBJECT] The subject of the present invention is to provide a heat-insulating structure for a car, the heat-insulating structure having a light weight, and excellent heat-insulating and sound absorbing performance. [METHOD FOR SOLVING THE SUBJECT] A heat-insulating and sound absorbing material is provided in the invention. The heat-insulating and sound absorbing material is characterized by an air-flow resistance controlling layer which lies between an air-permeable rigid layer and an air-permeable resilient layer, wherein the air-flow resistance controlling layer is a pulp fiber layer or a laminated layer of a pulp fiber layer and a nonwoven fabric having a mass per unit area in the range of between 10 and 50g/m2, a thickness in the range of between 0.08 and 0.30mm, and an air-flow resistance in the range of between 0.07 and 3.00 kPa.cndot.s/m. |
