Abstract
A composition and method of controlling a fire are disclosed. The composition contains a superabsorbent polymer, a colorant, an opacifying agent, and water. The method includes a step of applying the composition to a combustible object, either before or after initiation of combustion. The composition and method are especially useful for application to vegetation or foliage to prevent, retard, suppress, and/or extinguish forest fires and wildfires.
Claims15
A method of controlling a fire consuming a combustible object comprising a step of applying a sufficient amount of a fire-fighting composition to the combustible object to retard, suppress, or extinguish the fire, said fire-fighting composition comprising:
- (a) 0.01% to 20%, by weight, of a superabsorbent polymer;
- (b) 0.005% to 10%, by weight, of a colorant;
- (c) 0.005% to 10%, by weight, of an additional opacifying agent selected from the group consisting of calcium carbonate, a styrene-butadiene copolymer, a styrene-vinylpyrrolidone copolymer, a styrene-butadiene-acrylonitrile copolymer, an acrylic polymer, a polyvinyl acetate, a polyvinyl acrylate, a starch, a polyethylenimine, a polystyrene, a polyethylene, a polyvinyl alcohol, and mixtures thereof;
- and
- (d) water.
A composition comprising
- (a) 0.1% to 5%, by weight, of a superabsorbent polymer;
- (b) 0.015% to 2%, by weight, of a colorant;
- (c) 0.015% to 2%, by weight, of an additional opacifying agent selected from the group consisting of calcium carbonate, a styrene-butadiene copolymer, a styrene-vinylpyrrolidone copolymer, a styrene-butadiene-acrylonitrile copolymer, an acrylic polymer, a polyvinyl acetate, a polyvinyl acrylate, a starch, a polyethylenimine, a polystyrene, a polyethylene, a polyvinyl alcohol, and mixtures thereof;
- and
- (d) water.
