摘　　要：以聚磷酸铵为酸源、季戊四醇为炭源、三聚氰胺为气源,聚丙烯酸酯为粘合剂,将膨胀型阻燃剂应用于织物阻燃中,并加盖水性聚氨酯,研究了不同配比对织物阻燃性能的影响。三组分在合适比例下,形成致密完整、膨胀光滑的发层。对炭层用扫描电镜(SEM)和能谱仪(EDS)进行分析,结果表明,炭层磷含量远远超过阻燃涂层中原始含量,磷、硅、炭等阻燃成分富集于炭层表面,起到关键的隔热隔氧阻燃作用。膨胀型阻燃涂层应用于织物,可获得良好手感和较小色差,低烟少毒,但水洗后阻燃性能有所下降。Intumescence flame retardant （IFR） coating gum was prepared by using waterborne polyacrylic ester as binding agent while ammonium polyphosphate as acid source, pentaerythritol as carbon source, and melamine as gas source. The gum was applied on poly （ethylene terephthalate） （PET） fabric and then waterborne polyurethane （PU） was added coating. Compact, integrate and smooth carbon layer was obtained when the content of three flame retardant was kept at some range, The residue carbon layer was characterized by scanning electron microscopy （SEM） and energy dispersive spectrometer （EDS）. It shows that the content of P in residue carbon is far more than in prime gum, and P, C, Si is enriched in residue carbon, which plays great flame retardant role. Good handle, less chromatism, lower smoke and less toxicity is obtained as IFR is applied on PET fabric. But the flame retardant performance of the fabric decreases after laundering-recycle.
