FIREPROOF LAMINAR SOUND-AND-HEAT-INSULATING MATERIAL Russian patent published in 2012 - IPC B32B7/02 B64C1/40 

FIELD: process engineering.

SUBSTANCE: invention relates to production of laminar sound-and-heat-insulating fireproof materials for airliners. Proposed material comprises sound-and-heat-insulating and fireproof layers based on inorganic fiber impregnated with heat-resistant binder and lined by heat-resistant material. The latter incorporates basalt finer as said inorganic fiber of sound-and-heat-insulating layer. Silica fiber is used as inorganic fiber of fireproof layer. Additionally, proposed material comprises a layer of nonwoven needle-punched fabric based on aramide fibers impregnated with composition based on water dispersion of copolymer of vinyl chloride with vinyliden chloride and vinyl acetate.

EFFECT: higher operating properties of proposed material.
