Urea and borates for fire and termite control

摘要

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.
