A novel phosphorus-containing flame retardant, ammonium starch phosphate (ASTP) based on biomass starch, was synthesized for cotton fabrics, and its structure was characterized by 1D and 2D NMR. The limiting oxygen index (LOI) of the cotton fabric treated with 30 % ASTP reached 45.2 %, and the LOI remained at 32.1 % after 50 laundry cycles, indicating that the cotton fabrics treated with ASTP had a high flame retardancy and semi-permanent wash durability. The semi-permanent wash durability, Fourier transform infrared spectroscopy (FT-IR) and the SEM results suggested ASTP was grafted on the surface of cotton fibers by P-O-C covalent bonds. Vertical flammability, the thermogravimetry (TG) and cone calorimetry results showed that the cotton fabrics treated with ASTP had excellent flame retardancy. There were some reductions in the physical properties of the treated cotton fabric. Overall, these results suggested that starch can replace polyhydric alcohols to prepare a more durable formaldehyde-free P-based flame retardants.
一种新型含磷阻燃剂——基于生物质淀粉的磷酸淀粉铵（ASTP）被合成用于棉织物，并通过 1D 和 2D NMR 对其结构进行了表征。经 30%ASTP 处理的棉织物的极限氧指数（LOI）达到 45.2%，经过 50 次洗涤循环后，LOI 仍保持在 32.1%，表明用 ASTP 处理的棉织物具有高阻燃性和半永久性耐洗性。半永久性耐洗性、傅里叶变换红外光谱（FT-IR）和 SEM 结果表明，ASTP 通过 P-O-C 共价键接枝在棉纤维表面。垂直燃烧性、热重（TG）和锥形量热法结果表明，用 ASTP 处理的棉织物具有优异的阻燃性。处理后的棉织物的一些物理性能有所下降。总的来说，这些结果表明，淀粉可以替代多元醇来制备更持久的无甲醛磷基阻燃剂。
