碩士 === 國立臺灣科技大學 === 纖維及高分子工程研究所 === 88 === Abstract The high flame propagation rate of textile material is the major cause of the fire . PU-finishing is an important . Therefore , it is very significant to develop flame-retarding PU to meet the demand of flame resistance as well as functionality . This project will first synthesized flame-resistant agent containing synergetic nitrogen and phosphorous . This fire-resistant agent added to enviormental anionic waterbrone polyurethane . Then to produce crosslinking reaction , and investigate its application on the coating of nylon fabrics . To improve the water-vapor-permeability , these additives (SAA16、SAA140、TEA) will also be introduce into the waterbrone PU . The synthesis will use H12MDI as the hard-segment , DMPA as the ionic center , to form anionic aqueous PU . Then , this fire-resistant agent crosslinking with aqueous PU . The synthesized PU will be coated onto the fabrics . To improve the water-vapor-permeability , the other additives will also be added to the finishing liquors . On composition , the increase of fire resistant agent will be to increase with Tg and Tm . On different soft-segment：ester base PU''s Tg is higher ether . This phosphate conduce to product the char yield to resistant the oxygen gas , and change PU degradation by radical reaction . The synthesis of T650-0.7 and E1000-0.7 have best at 13.1% on TGA , water-vapor-permeability have PTMG>PEG>PCL ,Breaking strength have PCL>PTMG>PEG ,Limit Oxygen Index have PEG>PTMG> PCL . On different additives：T1000-0.7-SAA140 have the best physical equilibrium .
