Biodegradable fire resistant foam

摘要

The instant invention is a fire protectant composition comprising water, a surfactant, a water-soluble polymer, casein, and a calcium salt. The compositions can be applied to materials such as wood in advance of a fire, and after application, the compositions are capable of retaining their fire protectant capacities for days, weeks or even months. This fire protectant composition is also biodegradable and nontoxic. It is also easily removed from the combustible material by a water wash once the fire danger is passes. If burned, the composition forms a “skin” which can be peeled off or removed by some other method such as pressure water spray or mechanical brushing.
