Document Type and Number:
WIPO Patent Application WO/2015/093686
Kind Code:
A1
Abstract:
The present invention relates to a sound-absorbing/insulating material having improved heat resistance and moldability and a method for producing same and, more specifically, to a sound-absorbing/insulating material and a method for producing same, the sound-absorbing/insulating material having a structure in which a heat-resistant material, which is produced by impregnating a non-woven fabric comprising heat-resistant fibers with a binder, is stacked as a surface layer on one surface of a base layer made of a conventional sound-absorbing/insulating material. The sound-absorbing/insulating material according to the present invention has improved sound-absorbing properties, flame retardancy, heat-insulating properties, and heat resistance compared with a conventional sound-absorbing/insulating material; in particular, can be applied to a part maintained at a high temperature of at least 200℃, with the surface layer as a contact surface; and has the effect of allowing molding into a desired shape while the binder impregnated into the surface layer is hardening. Accordingly, the sound-absorbing/insulating material according to the present invention can widely be applied to industry fields requiring the sound-absorbing/insulating material, such as the field of electrical products such as air conditioners, refrigerators, washing machines, and lawn mowers, the field of transport equipment such as automobiles, vessels, and aircraft, and the field of building materials such as wall materials and floor materials.
