A New Intumescent Flame Retardant on Epoxy Resin

Abstract:

The cheaper phosphoric acid was uesd to replace the phosphorus oxychloride, starch was used to replace pentaerythritol and water as solvent to synthesize a new low-cost intumescent flame retardant (IFR)—starch phosphate ethylenediamine salts. The structure of the IFR was characterized with infrared spectroscopy. The IFR was used to impart flame retardancy to the Epoxy self-leveling floor (Epoxy Resin, EP) to get the fireproof Epoxy self-leveling floor. The results of test showed that 20% of IFR limit oxygen index of EP/IFR composite reach 31.0%. The results show that flame retardant catalyze the pyrolysis of epoxy resin into charcoal; Vertical burning passed UL94 V-0 rating.
