Abstract:
A method for reducing combustibility and termite damage of a more flammable organic material comprising incorporating urea-alkali metal and/or alkaline earth metal-boron oxyacid salt condensate on or in the more flammable organic material, under reaction conditions of the more flammable organic material, under reaction conditions of the more flammable organic material, said urea-alkali metal and/or alkaline earth metal-boron oxyacid salt condensate produced by the method comprising of mixing and reacting and optionally heating the following components:(A) urea, in the amount of 100 to 200 parts by weight of urea; (B) boron oxyacid salt, in the amount of 25 to 100 parts by weight of boron oxyacid salt; (C) alkali metal and/or alkaline earth metal oxide or hydroxide, in the amount of 25 to 75 parts by weight of alkali metal and/or alkaline earth metal oxide or hydroxide; then add and mix (D) water, in the amount of 0 to 1000 parts by weight of water; (E) carbonization auxiliaries, in the amount of 0 to 200 parts by weight of carbonization auxiliaries; (F) metal containing compound that accelerates carbonization, in the amount of 0 to 30 parts by weight of metal containing compound that accelerates carbonization; (G) heat reflecting compound, in the amount of 0 to 30 parts by weight of heat reflecting compound; (H) filler, in the amount of 0 to 200 parts by weight of filler; (I) surfactant, in the amount of 0 to 30 parts by weight of surfactant.
