Abstract

Abstract: Vermiculites were modified by acid treatment and Na ion exchange and was intercalated by hexadecyltrimethylammonium bromide(HDTMA·Br) leading to an organic vermiculite(OVMT). XRD indicated that the layers of vermiculite were dclaminated by HDTMA+ and the spacing distance was increased from 1 .49 nm to 4. 53 nm. Flame-retarded rigid polyurethane foams were prepared by introducing OVMT and ammonium polyphosphate(APP).When 5 % OVMT and 10 APP were introduced from LOI of 26 .8 % was achieved .DSC-TG showed that decalescence temperature was increased 358.1℃to 369.h℃.

Key words: rigid polyurethane foam, vermiculite, intercalation, flame retardancy, ammonium polyphasphatc
