| 摘 要： | 以N,N-双(2-羟甲基)氨乙基膦酸二甲酯与甲苯二异氰酸酯反应,合成了本质阻燃的磷-氮协效阻燃水性聚氨酯(PU);将其应用于涤丝纺织物,考察了织物阻燃性、静水压、色变和撕破强力等性能的变化;并用扫描电镜(SEM)和能谱仪(EDS)对PU整理的涤丝纺织物燃烧后的炭层进行分析.试验结果表明,与未整理织物相比,用阻燃剂含量为15%的PU整理,涤丝纺织物的LOI值提高了5.1%,垂直燃烧性能达到GB/T 5455-1997 B1级;涤丝纺织物燃烧后表面形成致密、光滑、无孔洞的炭层,炭层中磷含量超过阻燃织物中原始含量,磷富集于炭层表面,覆盖在织物表面,具有良好的阻燃能力;织物耐静水压随着阻燃剂含量的增加而急剧增大;经PU整理的织物色变小,总色差值均小于1.8,织物呈原色.

| Abstract: | A flame retardant waterborne polyurethane is prepared using N,N-bis(2-hydroxymethyl) aminoethyl phosphonic aciddimethyl ester and toluene diisocynate, and it is applied to fire proofing of polyester fabric. The properties of flame retardancy,hydrostatic pressure, color change and tear strength are investigated. The residue carbon layer is characterized by scanning e-lectron microscopy (SEM) and energy dispersive spectrometer (EDS) as well. The results show that when the content offlame retardant mass percen... |
