초록 ▼

There is disclosed a method of coating combustible material such as wood, plywood, shingles and the like with a flameproofing composition. The method employs a flame coating composition which is a mixture of a thermoplastic, ambient-temperature, film former such as a polyvinyl acrylic acetate latex, and alumina trihydrate and glass fibers. The ambient temperature film former is a conventional latex used for coating compositions and should have the property of softening at or below the dehydration temperature of alumina trihydrate (about 280 degrees F.) and be capable of forming a stable foam at such temperatures. The alumina, which comprises the major portion of the coating composition, dehydrates when subjected to flame temperatures and the water vapor released from the alumina forms a stable foam. Additionally, the alumina and the glass fibers, which are used as a filler in the composition, form a refractory coating when subjected to flame and this coating traps the gases and serves as a refractory heat insulation that protects and isolates the combustible material from exposure to the flame and ignition.
