ABSTRACT:
A process and product for increasing the flame resistance and thermal insolation properties of chemically treated substances, in some cases providing the treated substance with flame resistance at temperatures higher than 1800.degree. C. (direct fire), with no limit to the time of exposure. A number of embodiments of flame resistant compositions are discussed herein but all embodiments include a mixture containing water, inorganic acids, ammonium salts, sodium carbonate and pyrophosphate and, in some instances other constituents. The disclosed process treats substances to prevent the generation of any flames. The substances that have successfully been tested with the disclosed process include cloth (natural and synthetic), rugs and carpets, wood, cardboard, and paper. However, it is believed that this process can be applied to an unlimited number of flammable cellulose substances. With respect to the treatment of cloth, another advantage asserted for the disclosed process is that the texture and colors of the treated cloth are minimally affected, if at all. The cloth will not look or feel hard, thick or tough. Furthermore, the chemical treatment of the cloth will last through six months of domestic washing. A further application of the disclosed invention is as a coating on foam, particularly polyurethane foam and laminated foam. Applying the disclosed invention to foam material results in a resistance to all fire, not just an impedance to the flame for a limited period of time as known in the prior art. An even further application of the disclosed invention is as an additive to paint, resulting in an increase in the paint's tolerance to fire. This increase in thermal resistance would necessarily be transferred to any articles coated with said paint.
