Synthesis of a Flame Retardant Containing Nitrogen-phosphor and Its Application on Silk Fabric

摘要

In this paper, a flame retardant methacryloyl ethyl diethyl phosphoric amide (PN) containing nitrogen-phosphor for textiles was synthesized from phosphorus trichloride, absolute ethylalcohol, carbon tetrachloride, monoethanol amine, methacryloyl chloride. PN oil-in-water emulsion was grafted onto silk fabric by Atom Transfer Radical Polymerization (ATRP) method. The grafting technological parameters were investigated. The flame retardancy property of the treated silk fabric was indicated by LOI value, char length, after flame and after glow time.
