THERMAL-INSULATION SEALER Russian patent published in 2003 - IPC

FIELD: heat protection. SUBSTANCE: invention relates to fire-retardant antismoke equipment, in particular to devices preventing propagation of smoke through fissures and apertures based on thermally foaming compositions. Sealer is prepared from mixture containing binding agent (e.g., chlorosulfonated polyethylene), chemically oxidized graphite granules, magnesium oxide, zinc oxide, diphenylguanidine, ammonium salts or boric acid, or borax. Mixture is laid inside protective layer, over which adhesive parcels can be applied. Mixture can further contain pigments and/or inert substances. EFFECT: ensured constructively programmed elasticity, strength, and color of sealer, ingredient granule packing density, and desired composition of ingredient granules in vicinity of graphite granules thereby influencing derivatometric characteristics of thermally affected processes. 19 cl, 1 dwg
