摘　　要：以甲基磷酸二甲酯(DMMP)和乙二醇为原料,通过对反应条件的探讨,得到优化的合成工艺,制备出一种羟基磷酸酯型低聚物无醛阻燃剂,并用IR、1H-NMR和31P-NMR谱表征其结构。将其用于纯棉织物的阻燃整理,探讨了阻燃剂用量、交联剂用量和焙烘温度对阻燃效果的影响,优化了阻燃整理工艺。热解重量分析结果表明,阻燃整理后棉织物的主要裂解温度下降了47.05～75.86℃,燃烧后织物残渣量增加了67%,表明织物不易燃烧。扫描电镜结果表明,未阻燃织物燃烧后出现碳层坍塌现象,而阻燃织物依然保持纤维状,具有良好的阻燃性。整理织物洗涤12次后,仍能达到国标B2级,表明其具有良好的耐洗性。An oiigomeric phosphate ester non-formaldehyde flame retardant containing hydroxyl was synthesized from DMMP and glycol, and its structure was characterized by IR, ^1H-NMR and ^31P-NMR. By discussing the reaction conditions, the optimal synthesis process was obtained. The cotton fabric was finished by the flame retardant and the process was optimized by exploring the amount of flame retardant and crosslinker, and curing temperature. TGA showed that the main pyrolysis temperature of the finished cotton declined by 47.05 - 75.86℃ , and the amount of residue increased by 67% after being burned. It proved that the fabric was difficult to burn. SEM showed that when the cotton fabric without flame retardant finishing burned, its carbon layer collapsed. On the contrary, the flame retardant finished cotton kept the original fibroid conformation, showing good flame retardancy. After 12 times of washing, the flame retardant finished cotton was still up to the standard GB B2 , indicating good washing fastness.
