LAYERED FIRE-RETARDANT MATERIAL Russian patent published in 2001 - IPC

FIELD: fire-protective garments. SUBSTANCE: material is constructed in the form of packet and contains outside layer made from fire-protective fibers, intermediate heat- insulation layer, inside cotton cloth layer, and waterproofing layer made from siloxane composition disposed between intermediate layer and outside layer, which, together with the latter, constitutes 0.02 to 0.05 thickness of intermediate layer. The siloxane composition contains synthetic low-molecular silicon-containing liquid rubber with special-type filler, 3.5 to 30 wt.pts per 100 wt.pts rubber, in the form of polymer mixture and methyltriacetoxyl-based hardener in amount 3.5 to 5.0 per 100 wt.pts of polymer mixture. EFFECT: improved bend and wear resistance and decreased consumption of polymer for waterproofing layer. 1 tbl, 3 ex
