FIRE-PROTECTION TEXTILE MATERIAL Russian patent published in 1998 - IPC

FIELD: fire-protection materials. SUBSTANCE: fire-resistant textile material is made as cloth with fire- protection coating discretely distributed over the surface of cloth in the form of hemispheric elements 0.8-2.0 mm in diameter. Coated surface constitutes 15-45% of total surface of cloth. Coating contains, as fire retardant, antimony trioxide, urea, tris(2,3- dibromopropyl) phosphate, ammonium phosphate, or their mixture. As binding agent, coating contains polyvinylchloride paste at weight ratio to fire retardant 100:(10-45). Characteristics: fire resistance 0-9 s, heat-protection property 10.8-12.2 cal/sq.cm; air permeability 190-240 cu.dm/sq.m s; abradability 3500 cycles. Material is appropriate to be used for manufacturing means for individual heat protection. EFFECT: improved performance characteristics. 1 tbl
