This paper mainly studied the structure and the properties of the waterborne polyurethane, preparation, in flame retardant agent to discuss the analysis of the flame retardant classification, inanic flame retardant agent。 In the anic phosphorus flame retardant modified waterborne polyurethane study, design the experimental process, the performance test, finally gives the infrared spectral analysis, pre polymers of P content influence WPU emulsion particle size and limit oxygen index and vertical bustion research。 In the electronic label application of waterborne polyurethane in the analysis, this paper discusses the crosslinking type PUA posite emulsion, selfcrosslinking PUA posite emulsion, interperating work PUA posite emulsion, epoxy resin modified waterborne polyurethane emulsion, finally the electronic tag antenna base material application research. Research shows that the FRC 6 to substitute other small molecule glycol chain extension agent, can synthesize more stable anophosphorous flame retardant modification of waterborne polyurethane。 If P content to remain in a certain range, then P content in pre polymers in the increase of mass fraction of at the same time can also affect PU heat release rate, which reduce heat release quantity, increases the LOI, improve the flame retardant performance, etc. If the content of P in the prepolymerization body mass fraction is end %, and ABSTRACT III oxygen index is 28%, UL 94 v grade 2 is vertical burning PU flame retarding performance level。 Will DMAc as solvent, can improve the efficiency of prepolymerization body reaction. If you need to get appearance translucence emulsion, pre polymers in DMBA dosage must be controlled in 5%.
