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）制备了系列
BPAMPP 质量分数不同的阻燃水性聚氨酯（WPUP）。采用 NMR 和 FTIR 对 BPAMPP 进行了结构表征，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 被成功合成，且在 800 ℃下残炭率为 14.2%；WPUP 乳液具备良好的粒径分布
和贮存稳定性，当 BPAMPP 质量分数为 8%时，WPUP 膜的综合性能最佳，拉伸强度为 36.8 MPa，热失重 5%

Abstract: 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
isophoronediisocyanate (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 WPUP film exhibited the best comprehensive performance. The tensile strength was 36.8
MPa, 5% weight loss temperature was 288.3 ℃, the limiting oxygen index , peak heat release rate and total

heat of release were 26.8%, 631 kW/m and 76 MJ/m , respectively.
