摘要
以三氯氧磷(POCl3)、二乙胺(C4H11N)及甲基丙烯酸羟乙酯(HEMA)为主要原料,经过两步反应合成了乙烯基磷氮类阻燃剂PNFR。考察了温度和原料配比对中间体和目标产物产率的影响,并研究了PNFR接枝蚕丝织物的阻燃效果。结果表明:采用红外、核磁、质谱等对目标产物结构进行了表征,成功合成乙烯基磷氮类阻燃剂PNFR,且在优化合成工艺条件下的产率为90.4%;当接枝率为13%左右时,织物的极限氧指数(LOI)为28.8%,达到织物难燃的标准;织物经过50次水洗后,LOI仍有28.5%,阻燃耐洗性能良好。
The vinyl phosphorus-nitrogen flame retardant （PNFR） was synthesized with phosphorus oxychloride （POCl3）, diethylamine （C4H11N） and hydroxy ethyl methacrylate （HEMA） as the main raw material through two steps. The influence of the temperature and the ratio of raw materials on the yield of the intermediates and the target product were examined. The flame retardant effect of silk fabric grafted by PNFR was also investigated. The results show that the structure of target products is characterized with infrared spectrum, nuclear magnetic resonance and mass spectrum and PNFR was synthesized successfully. The yield of the target product can reach about 90.4% at the optimum synthetic technological conditions. The limited oxygen index （LOI） of silk fabric is 28. 8% when the grafting rate is about 13G, reaching the standard of flame retardant. The LOI is still 28. 5% after washing for 50 times, with good flame retardant performance.
