摘要
以六水合氯化镁为原料,氢氧化钠和氨水为沉淀剂,采用双滴加的方法,成功制备出粒径50 nm且分布较为均匀的纳米氢氧化镁。纳米氢氧化镁经离心烘干后,通过浸渍法整理到真丝织物上,优化的整理工艺为:纳米氢氧化镁用量40.6 g/L、温度80℃、浴比1∶50、时间1 h。经优化工艺整理后,真丝织物的极限氧指数(LOI)达到31.7%,损毁长度为11.0 cm,烟密度为13.71,比市售氢氧化镁整理的织物具有更好的阻燃性能和抑烟性能。
Using magnesium chloride hexahydrate as raw material, sodium hydroxide and ammonia as precipitants, nano magnesium hydroxide with uniform distribution and particle size of 50 nm was successfully prepared by double dripping method. After centrifugal drying, nano magnesium hydroxide were applied on silk fabric by dipping method. The optimized finishing process was as follows: the concentration of nano magnesium hydroxide 40.6 g/L, temperature 80 ℃, bath ratio 1∶50, time 1 h. After optimizing the process, the limiting oxygen index(LOI) of silk fabrics reached 31.7%, the damage length was 11.0 cm, the smoke density was13.71. It had better flame retardancy and smoke suppression performance than the fabrics treated with commercially available magnesium hydroxide.
