| Abstract: | This paper relates the preparation of blocked and waterborne polyurethane with the main materials of 4,4 - diphenylmethane diisocyanate(MDI) and polyglycol(Mw = 400) (PEG), the blocking agent of sodium bisulfite. The durable flame - retardant composition was synthesized by mixing blocked and waterborne polyurethane with FRC - 1 whose compatibility was good. The polyester cloth was finished by the flame -retardant composition added up with proper auxiliaries. The main factors that affected the results of flame retarding finishing were discussed, and the optimum finishing process condition was selected. The mechanism of durable flame retarding finishing was primarily discussed.The test results show that the novel flame- retardant composition has durable flame- retarding finishing effect on polyester cloth. |
