Aqueous urea condensate-boron oxyacid salts composition may be utilized to fight grass, forest, building, and other flammable organic material by applying it to these flammable organic materials. The solid or aqueous urea condensate-boron oxyacid salts composition may also be incorporated into flammable materials such as solid and foam plastic and natural materials. Urea condensate-boron oxyacid salts composition may also contain carbonization auxiliaries, such as phosphorus containing compounds, metal containing compounds that will accelerate carbonization, heat reflector, surfactant and fillers. The urea condensate-boron oxyacid salts composition is produced by mixing, heating and/or reacting urea, boron oxyacids and alkali metal hydroxide or alkaline earth metal hydroxide or oxide or the boron oxyacids maybe first reacted with the alkali metal hydroxide or the alkaline earth metal oxide or hydroxide.
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 flame retardant product containing termite insecticide produced by applying on and/or incorporating a solid or aqueous urea-boron oxyacid salt condensate on or in a more flammable organic material, under reaction condition or applying sufficient amount to reduce the combustibility of the more flammable organic material, the solid or aqueous urea-boron oxyacid salt condensate is produced by the process consisting of mixing and reacting and optionally heating the following components:
