US 12,599,798 B2 · Environmentally-clean fire inhibiting biochemical liquid compositions for forming thin alkali metal salt crystalline coatings on combustible surfaces to be protected against fire

Abstract

An environmentally-clean fire inhibiting liquid biochemical composition for application on combustible surfaces to inhibit fire ignition and flame spread in the presence of fire. The environmentally-clean fire inhibiting liquid biochemical composition including a dispersing agent realized in the form of a quantity of water, for dispersing metal ions dissolved in water; a fire inhibiting agent in the form of at least one alkali metal salt of a nonpolymeric saturated carboxylic acid, for providing metal ions dispersed in the water when the alkali metal salt of a nonpolymeric saturated carboxylic acid is dissolved in the quantity of water; and a coalescing agent in the form of an organic compound containing three carboxylic acid groups, or salt/ester derivatives thereof, specifically triethyl citrate (TEC), an ester of citric acid, for dispersing and coalescing the metal ions when the fire inhibiting liquid composition is applied to combustible surfaces to be protected against fire, while water molecules in the water evaporate to the environment during drying, and the metal ions cooperate to form thin alkali metal salt crystalline coatings on the combustible surfaces. The alkali metal salt of nonpolymeric saturated carboxylic acid may be selected from the group consisting of: alkali metal salts of citric acid; alkali metal salts of oxalic acid; alkali metal salts of gluconic acid; and alkali metal salts of tartaric acid. The alkali metal salt of nonpolymeric saturated carboxylic acid may be selected from the group consisting of the alkali salt of lithium, the alkali salt of sodium, the alkali salt of potassium, the alkali salt of cesium and the alkali salt of rubidium. Preferably, the alkali metal salt of nonpolymeric saturated carboxylic acid is an alkali salt of potassium, namely tripotassium citrate (TPC).
