摘　　要：通过对阻燃剂CP的氮羟甲基结构进行醚化改性,并与大分子聚氨酯无醛交联剂复配使用,从阻燃剂低甲醛和交联剂无甲醛两个方面,组成了低甲醛耐久棉织物阻燃体系。考察改性合成中,超声波温度及振荡时间对产物转化率的影响,以及阻燃剂、交联剂、柔软剂质量浓度对阻燃效果的影响。结果显示:使用超声波对反应原料进行活化,当超声温度60℃,超声振荡时间40min时,活化效果佳,反应产率高;优化的整理工艺配方为:阻燃剂300g/L,交联剂45g/L,柔软剂8g/L,整理后织物阻燃效果佳。A new durable low formaldehyde flame retardant system is prepared with modified CP （etheri- fication of original CP flame retardant） and formaldehyde-free polyurethane cross-linking agent. The influ- ences of ultrasonic treating temperature and time on conversion rate and the dosages of flame retar- dant, cross-linking agent and the softener on flame retardancy are discussed. The results show that the optimum activation effect of raw material can be achieved with ultrasonic treating at 60 ℃ for 40 min. The optimum finishing process is flame retardant 300 g/L, cross-linking agent 45 g/L and softer 8 g/Li the finished fabric has good flame retardancy.
