摘　　要：针对大多数磷-氮阻燃剂不耐氯的特性,以亚磷酸二乙酯、N-羟甲基丙烯酰胺、环氧氯丙烷为原料,甲醇钠、氢氧化钠为催化剂,分2步合成了磷-氮耐氯阻燃剂。通过正交试验确定最佳的合成工艺条件,对在最佳工艺条件下合成的阻燃剂进行了红外光谱分析,将其应用于亚麻织物的阻燃整理,并对整理后的亚麻织物进行了红外光谱分析和耐久性以及耐氯性测试。结果表明:经合成的耐氯阻燃剂整理后的亚麻织物炭长达5.8 cm,整理后亚麻织物经过20 mg/L的有效氯溶液浸泡1 h后炭长还可保持9 cm;阻燃亚麻织物经12次水洗后,仍能达到国家B2标准,证明成功合成了含磷-氮的耐氯耐久阻燃整理剂。Due to poor resistance to chlorine for most of phosphorus and nitrogen-containing flame retardant finishing agents, a phosphorus and nitrogen-containing chlorine-resistant flame retardant finishing agent was successfully synthesized by a two-step process using diethyl phosphate, N-hydroxymethyl acrylamide and epichlorohydrin as raw materials and sodium methoxide and sodium hydroxide as catalysts. The optimum synthetic conditions were determined by the orthogonal experiment, the flame retardant agent synthesized under the optimum conditions was characterized by infrared spectroscopy, and applied in the flame-retardant finishing of linen fabrics. The linen fabrics before and after finishing were characterized by infrared spectroscopy, the durability test and chlorine resistance test. The results indicate that the carbonized length of the linen fabrics finished with the synthesized chlorine-resistant flame retardant agent reaches 5.8 cm, the carbonized length after soaking with 20 g/L available chlorine solution for about 1 h still maintains at 9 cm. After 12 times of washing, the linen fabric finished by the flame retardant can still reach the standard GB B2, showing that a phosphorus and nitrogen-containing chlorine-resistant durable flame retardant finishing agent is successfully synthesized.
