FIRE RESISTANT FIBER SHEET, MOLDINGS THEREOF, AND FLAME-RETARDANT ACOUSTICAL ABSORBENTS FOR AUTOMOBILES

摘要

The object of the present invention is to provide a fiber sheet having goodfireresistant property, an expanded synthetic resin sheet having good fireresistant property and a molded article thereof, and a fire resistant acousticmaterial for cars, which uses the molded article.To attain the object, in the present invention, fire retardant capsules areadhered to the fiber sheet or the expanded synthetic resin sheet to provide aporous fire resistant sheet. When the fire retardant capsules are exposed to ahigh temperature, the synthetic film covering the fire retardant may break,exposing fire retardant, and giving fiber sheet or expanded synthetic resinsheet self extinguishing property. A molded article of the porous fireresistantsheet also has a good fire resistant property, and does not inhibit theventilation property of the fiber sheet and the synthetic resin sheet, makingsaid molded article useful as a fire resistant acoustic material for cars orbuildings.
