Abstract

In the present research, a glycosyl cross-linking coordination chelate flame retardant was designed to enhance durable flame retardancy of cotton fabrics. It was a halogen-free, non-formaldehyde boron acid and phytic acid ammonium salt synergistic flame-retardant system. The flame retardancy and durability of flame retardants prepared by different saccharides were investigated. Results showed that raffinose was the best cross-linking reagent compared with the other monosaccharides and oligosaccharides. The raffinose as cross-linking reagent prepared glycosyl cross-linking boron acid and ammonium salt of phytic acid flame retardant (r-GBAP) (100 g/L) can obtain the shortest char length of 56 mm and the largest limiting oxygen index (LOI) value of 37.4%. A lower r-GBAP concentration can get good flame retardancy, due to adopt the three curing cycles process. FTIR, XPS, LOI, TG and SEM testing and characterization techniques were used to analyze and research the flame retardancy, durability, thermal oxidation stability and flame-retardant mechanisms of r-GBAP and the treated cotton fibers.

糖基交联硼酸和植酸铵盐的协同阻燃剂，可增强棉织物的持久阻燃性

摘要

在本研究中，糖基交联配位螯合阻燃剂被设计用于增强棉织物的持久阻燃性。它是一种无卤，无甲醛的硼酸和植酸铵盐协同阻燃系统。研究了由不同糖类制备的阻燃剂的阻燃性和耐久性。结果表明，与其他单糖和寡糖相比，棉子糖是最好的交联剂。所述ř affinose作为交联试剂制备的克lycosyl交联b奥龙酸和一的mmonium盐p羟阻燃剂（r-GBAP）（100 g / L）可获得最短的焦炭长度为56毫米，最大极限氧指数（LOI）值为37.4％。由于采用了三个固化循环工艺，因此较低的r-GBAP浓度可以获得良好的阻燃性。用FTIR，XPS，LOI，TG和SEM测试和表征技术分析和研究了r-GBAP和经处理的棉纤维的阻燃性，耐久性，热氧化稳定性和阻燃机理。
