FIELD: process engineering.
SUBSTANCE: fire-proof paper is to be combined with fire-proof film laminate used in heat- and sound-proof systems normally used in civil aviation, etc. Fire-proof paper is used incorporated with fire-proof film. Fire-proof paper comprises inorganic biodegradable fiber, cut safe fiber, organic reinforcing fibers, organic binder and inorganic binder or filler, and, not obligatorily, fire-proof ceramic fiber.
EFFECT: higher resistance to damages in processing, reduced inflammability.
