摘要: 针对粘胶纤维出口需达到阻燃要求兼并服用安全无毒、易于工业生产问题,本文研究了通过粘胶纤维中分别加入阻燃剂TBEP、硅酸钠、三聚氰胺进行纺前共混制得阻燃粘胶纤维Ⅰ、Ⅱ、Ⅲ,采用极限氧指数法(LOI)、红外光谱法(FTIR)、热重分析法(TG)、差热分析法(DTA)、差热红外联用(DTA-FTIR)法等方法测试并研究其阻燃性能,其中阻燃粘胶纤维Ⅲ极限氧指数达32.8,达到难燃标准,通过红外光谱检测阻燃剂有效连接在粘胶纤维上。采用TG-DTA分析,显示阻燃剂的加入增强成炭作用,同时使阻燃粘胶纤维燃烧脱水阶段提前,氧化分解阶段反应平缓。通过差热—红外联用,检测出燃烧产物为水、CO、CO2,所使用的阻燃剂安全无危害性。

Abstract: The export demand of viscose fiber must be up to the standards of the flame retardants, taking the safe and nontoxic, and easy to problems of industrial production. The viscose fiber adds separately TBEP, sodium silicate, melamine by the method of spinning mixing. The flame retardant viscose fiber Ⅰ, Ⅱ, Ⅲ are obtained. The test and study on the flame retardant properties are evaluated by Limit Oxygen Index (LOI), infrared spectroscopy (FTIR), thermal gravimetric (TG), differential thermal analysis (DTA), and combined with differential thermal analysis and infrared spectroscopy (DTA-FTIR). The limit oxygen index of flame retardant viscose fiber Ⅲ could reach 32.8. FTIR shows that the flame retardants were effectively connected the to the viscose fiber. TG-DTA shows that the charring is enhanced, while the stage of the dehydration is advanced, and the stages of the oxidation and decomposition become gentle. DTA-FTIR suggests that the combustion product is water, CO, CO2. The flame retardants are safe and innocuous.
