摘　　要：为解决阻燃聚酯织物熔滴严重的问题,采用紫外光(UV)辐照接枝共聚技术,通过1-羟基环己基苯甲酮的光引发作用,将阴离子型丙烯酸(AA)接枝到阻燃聚酯织物表面,在此基础上设计了γ-氨丙基三乙氧基硅烷(KH-550)与磺丁基-β-环糊精(SBE-β-CD)抑熔滴体系,在接枝织物表面进行层层自组装制备阻燃抑熔滴聚酯织物,并对改性后织物的形貌、热稳定性和阻燃性能进行表征。结果表明:引发剂质量分数为4%,AA质量分数为12%,紫外光照射时间为10 min时,阻燃聚酯的接枝率较优,为5.08%,但随着接枝率的增加其极限氧指数(LOI值)有所降低;层层自组装改性后的聚酯织物,在组装层数为12时,其极限氧指数可达到28%,成炭明显,垂直燃烧测试无熔滴产生,燃烧性能得到明显改善。In order to solve the problem of droplet of flame retardant polyester fabrics,ionic monomers acrylic acid(AA)were grafted on the surface of flame-retardant polyester fabric in the presence of 1-hydroxycyclohexyl benzophenone as photoinitiator under the irradiation of ultraviolet light(UV).After that,γ-Aminopropyl triethoxysilane(KH-550)and sulfobutyl ether-β-cyclodextrin(SBE-β-CD)were designed as an anti-droplet system and flame retardant anti-drop polyester fabric was fabricated by layer-by-layer self-assembly on the grafted fabric surface.The morphologies,thermal properties and combustion properties of the fabrics before and after self-assembly were characterized.The results showed when the initiator mass fraction is 4%,the AA mass fraction is 12%,and the UV irradiation time is 10 min,the grafting rate of the flame retardant polyester is better,which is 5.08%.But the limiting oxygen index(LOI)decreases with the increase of grafting rate.The LOI of modified polyester fabric is 28%and the char residue increase when the number of assembled layers is 12.The vertical combustion test has no droplets,and the combustion performance of polyester fabrics are significantly improved.
