摘　　要：以亚磷酸二甲酯和3-溴丙烯为原料,制备了反应型阻燃剂丙烯基磷酸二甲酯(DA)。利用N,N’-亚甲基双丙烯酰胺(MBA)交联剂,以安息香双甲醚为光引发剂,在365 nm紫外光照射下,引发DA接枝到棉织物上,对棉织物进行阻燃整理。研究DA和MBA的质量浓度对棉织物阻燃性能的影响。结果表明:棉织物阻燃性能随DA和MBA质量浓度的增加而提高,棉织物极限氧指数(LOI)可达27.2%,续燃时间和阴燃时间均为0 s,经20次洗涤后,LOI仍达24.5%。整理后棉织物具有更好的热稳定性能,阻燃整理对棉织物的拉伸性能无显著影响。Reactive flame-retardant dimethly allylphosphonate(DA)was prepared using dimethyl phosphite and 3-bromopropy and was grafted onto cotton fabric via ultraviolet(UV)irradiation using N,N'-Methylenebis(2-propenamide)(MBA)as a crosslinker and benzoin dimethyl ether as an initiator.The effects of DA and MBA mass concentrations on the flame retardancy of the cotton fabric were studied.The results indicated that the flame retardancy of the cotton fabric was proportionate to the mass concentrations of DA and MBA.The limiting oxygen index(LOI)of the cotton fabric could reach 27.2%,and the afterburning time and smoldering time were both 0 s.After 20 washing turns,the LOI could still reach 24.5%.The final cotton fabric exhibited better thermal stability,and the flame-retardant finishing demonstrated no significant effect on the tensile property of the cotton fabric.
