A novel, high-efficiency, phosphorus-nitrogen flame retardant based on tea polyphenol-melamine-phenylphosphonic acid (named TP-MA-PPOA) for cotton fabrics was prepared successfully. TP-MA-PPOA coating gives the cotton fabrics flame retardancy and anti-UV properties. The results reveal that the TP-MA-PPOA coating enables cotton fabrics to self-extinguish, the damage length is only 7.4 cm in vertical flame test, and the limiting oxygen index increases to 28.7%. Meanwhile, Cotton/TP-MA-PPOA also performs well in cone calorimetry test, as evidenced by 88.5% reduction of peak heat release rate, and 92.9% decrease of the fire growth rate compared with that of cotton fabrics. And the risk of fire is sharply reduced. In addition, the ultraviolet protection factor value of Cotton/TP-MA-PPOA is 35.2. Encouragingly, the TP-MA-PPOA coating shows little deterioration in the handle of the cotton fabrics.
成功制备了一种基于茶多酚-三聚氰胺-苯基膦酸的新型高效磷氮阻燃剂（命名为TP-MA-PPOA）用于棉织物。TP-MA-PPOA涂层赋予棉织物阻燃性和抗紫外线性能。结果表明，TP-MA-PPOA涂层能使棉织物自熄，垂直燃烧试验中损毁长度仅为7.4厘米，极限氧指数提高到28.7%。同时，棉/TP-MA-PPOA在锥形量热试验中也表现良好，与棉织物相比，热释放峰值速率降低了88.5%，火灾增长速率降低了92.9%。火灾风险大幅降低。此外，棉/TP-MA-PPOA的紫外线防护系数值为35.2。令人鼓舞的是，TP-MA-PPOA涂层对棉织物的手感几乎没有不良影响。
