摘要/Abstract

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，得到了优化的合成工艺，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谱对其结构进行了表征。利用所制阻燃剂对棉织物进行阻燃整理，探讨了阻燃剂用量、交联剂用量和焙烘温度对阻燃效果影响，优化了阻燃整理工艺。热解重量分析结果：经阻燃整理棉织物的主要裂解温度下降了50℃左右，燃烧后织物残渣量增加了近1倍，表明织物不易燃烧。扫描电镜结果：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。洗涤12次后，仍能达到国标B2级，表明整理棉织物具有良好的耐洗性。

Abstract: An oligomeric phosphate ester non-formaldehyde flame retardant containing hydroxyl was synthesized by DMMP and glycol, and its structure was charactered by IR、1H-NMR and 31P-NMR. After discussing the reaction conditions, we got the optimal synthesis process. The cotton fabric was finished by the flame retardant and the process was optimized by exploreing the amount of flame retardant and crosslinker and the curing time. TGA showed that the main pyrolysis temperature of cotton after being finished by flame retardant declined about 50℃, and the amount of residue doubled 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 cotton kept the original fibroid conformation and had a good flame resistance. After 12 times of washing, the flame retardant cotton was still up to GB B2 and showed a good washing fastness.

Key words: DMMP, glycol, non-formaldehyde flane retardant, cotton fabric, crosslinker
