Near vacuum fire retardant material reduces the noise and preserves heat to be used for ceiling and indoor compartment board

Abstract

At present, all public spaces and offices around the world use light steel hangers and 2′×2′ ceiling board or 4′×8′ indoor compartment gypsum board for the beauty and fire protection. Thermally soundproof, but the board is not encapsulated with a metal film and then vacuumed. In the long term, the moisture of the water molecules contained in the micron-sized pores would have been transported through the asbestos fibers, therefore become the medium for conducting sound waves and heat. It is necessary to enclose the board with metal film and then vacuumed in order to improve fire and sound insulation.

1 . The utility relates to a near vacuum fire retardant material that reduces the noise and preserves heat be used for using ceiling and indoor compartment board, which are characterized in that: Using environmentally-friendly non-toxic recoverably hearthstone or stone, pumice granules, or cracked ceramic material, to make lightweight board ( 12 ), sealed between the lower aluminum foil film ( 11 ) and the upper aluminum foil film ( 13 ) ( 14 ). On upper aluminum foil film ( 13 ) heat seals an air suction valve ( 15 ) at a suitable position, and pumps the ceiling and the indoor partition board ( 12 ) to a vacuum by ( 15 ). The combination can be used for building applications.
