中文摘要:
      以双酚A(BPA)和苯膦酰二氯(BPOD)为原料,合成了一种含磷阻燃单体双(双酚A)单苯基膦酸酯(BPAMPP),并以其作为扩链剂与聚氧化丙烯二醇(PPG)和异佛尔酮二异氰酸酯反应(IPDI)制备了阻燃水性聚氨酯(WPUP)。采用NMR和FTIR对BPAMPP结构进行了表征,通过粒径分析、拉伸测试、TGA、极限氧指数测试和锥形量热仪测试研究了WPUP的乳液性能、力学性能、热性能和阻燃性能。结果表明,BPAMPP被成功的合成,且在800℃下残炭的质量分数为14.2%;WPUP乳液都具备良好的粒径分布和贮存稳定性,当BPAMPP质量分数为8 %(占原料的总质量)时,水性聚氨酯膜的综合性能最佳,拉伸强度为36.8MPa,5%质量分数的热失重温度为288.3℃,极限氧指数(LOI)、峰值放热速(PHRR)和总释放热(THR)分别为26.8%、631 kW/m2和76 MJ/m2。
英文摘要:
      A phosphorus-containing flame retardant monomer, bis(bisphenol A) monophenyl phosphonate (BPAMPP), was synthesized from bisphenol A (BPA) and benzene phosphorous oxydichloride (BPOD) and used as chain extender. A series of flame retardant waterborne polyurethanes (WPUP) with different mass fractions of BPAMPP were prepared by chain reaction of polyoxypropylene glycol (PPG) and isophorone diisocyanate (IPDI). The product BPAMPP was characterized by NMR and FTIR. The emulsion properties, mechanical properties, thermal properties and flame retardancy of WPUP were studied by particle size analysis, tensile test, TGA, limiting oxygen index test and cone calorimeter. The results showed that BPAMPP was successfully synthesized, and its char residue was 14.2% at 800℃. The WPUP emulsions had good particle size distribution and storage stability. When the mass fraction of BPAMPP was 8%, the prepared waterborne polyurethane film exhibited the best comprehensive performance. The tensile strength was 36.8 MPa, 5% weight loss temperature was 288.3℃, the limiting oxygen index (LOI), peak heat release rate (PHRR) and total heat of release (THR) were 26.8%, 631 kW/m2 and 76 MJ/m2, respectively.
