摘　　要：为解决纯棉织物的阻燃及其耐洗性问题,以生物质植酸和双氰胺为原料,制备了无卤生物质环保耐洗阻燃剂PD,并应用于棉织物的阻燃整理。借助傅里叶红外光谱仪和X射线能谱仪等分析表征了PD化学结构和元素组成,并对整理织物的表面形貌、热稳定性、阻燃及耐水洗性等进行了分析。结果表明:阻燃剂PD为多活性磷氮型阻燃剂;纯棉织物阻燃整理时,阻燃剂PD质量分数为35%;PD处理样在800℃热解残炭量为13.32%(氮气气氛),垂直燃烧的损毁长度为4.5 cm,极限氧指数达43.6%,且阻燃织物经40次标准洗涤后,极限氧指数仍能达到29.1%;制备的阻燃剂PD是一种阻燃效果和耐水洗性能优良的生物质环保阻燃剂。In order to improve flame retardancy and washability of pure cotton fabrics,a halogen-free environment-friendly durable flame retardant PD was synthesized with biomass phytic acid and dicyandiamide,which was applied to the flame retardant finishing of a cotton fabric.The chemical structure and elemental composition of flame retardant PD were characterized by Fourier transform infrared spectrometer and X-ray energy spectrometer,and the surface morphology,thermal stability,flame retardancy and washability of the treated fabric were investigated.The results show that flame retardant PD is a multi-active phosphorus-nitrogen flame retardant;the mass fraction of flame retardant PD is 35%in the flame retardant finishing of cotton fabric.The residual carbon amount of PD flame retardant treatment sample is 13.32%at 800℃pyrolysis(nitrogen atmosphere),and the fabric damage length of vertical combustion is 4.5 cm.The LOI value of the flame retardant fabric reaches 43.6%,and it can still reach 29.1%after 40 times of standard washing.It demonstrates that a biomass environment-friendly flame retardant PD offers excellent flame retardancy and washability.
