Claims8
A method of retarding the effect or degree of a fire comprising:
- applying a fire-retardant hydrogel preparation to a fire-prone area wherein the fire-retardant hydrogel preparation comprises an ammonium polyphosphate retardant and hydroxyethylcellulose, methylcellulose, and colloidal silica particles, and wherein the hydroxyethylcellulose and methylcellulose are cross-linked by the colloidal silica particles to form a non-covalently crosslinked hydrogel.
