Development and Evaluation of Practical Self-Help Fire Retardants.
Abstract
The study was conducted to (1) determine whether high molecular weight, high oxygen containing inorganic additives can be effectively used in developing nonleachable flame retardants for self-help application to existing roofs, (2) investigate the kinetics and thermal decomposition of cotton and synthetic polymers, and (3) modify the Parker-Lipska (P-L) model to more closely predict the empirical increase in char yield in retardant treated cellulosics. The sprayed-on, interstitially precipitated ammonium phosphomolybdate, ammonium phosphotungstate, and magnesium ammonium phosphate afford seasonal (no more than 30 inches of rain) protection againstfirebrands. Similarities in the weight-loss kinetics and products of pyrolysis of cotton and wood-derived cellulose suggest that the guidelines used in the P-L model in chooding retardants might be applied to all cellulosic materials.
