Abstract:
A method for reducing combustibility of a more flammable organic material comprising incorporating an aqueous or solid urea condensate salt of sulfur oxyacid and/or aqueous or solid urea condensate salt of sulfur oxyacid composition on or in the more flammable material, under reaction conditions of the more flammable organic material, said aqueous or solid urea condensate salt of sulfur oxyacid and/or composition produced by the method comprising of mixing, heating and reacting the following components:(A) urea condensate, in the amount of 25 to 200 parts by weight of urea condensate; (B) sulfur oxyacid and/or sulfur oxyacid salts that will react with urea, in the amount of 5 to 50 parts by weight of sulfur oxyacid and/or sulfur oxyacid salts; then add and mix (C) metal containing compound that accelerates carbonization, in the amount of 0 to 30 parts by weight of metal containing compound; (D) heat reflecting compound, in the amount of 0 to 30 parts by weight of heat reflecting compound; (E) filler, in the amount of 0 to 300 parts by weight of filler; (F) surfactant that assist in the formation of bubbles, in the amount of 0 to 30 part by weight of surfactant; (G) water, in the amount of 0 to 500 parts by weight of water.
