摘要: 以NaOH为缚酸剂,水为溶剂,在OP-10存在下,通过三聚氯氰与哌嗪缩聚合成了哌嗪基超支化三嗪成炭剂,并通过热重分析研究了它们的热稳定性和成炭性。结果表明,其较佳合成条件:n(三聚氯氰)∶n(哌嗪)∶n(NaOH)=10∶15∶30,w(三聚氯氰)∶w(水)∶w(OP-10)=10∶27∶009,10~15 ℃缩合25 h,50~55 ℃缩合25 h,90~95 ℃缩聚6 h。在以上条件下,产品的产率、氯含量和水溶性分别为973%、055%和021 g·(100 mL)-1水,产品的热稳定性和成炭性良好。该合成方法不采用低沸点溶剂,不仅减少了污染、安全性更好,而且合成工艺和设备更加简单。

Abstract: The piperazine-based hyperbranched charring agent was synthesized through condensation polymerization of cyanuric chloride with piperazine by using water as a solvent and NaOH as an acid binding agent in the presence of OP-10, and its thermal stability and charring property were studied by thermogravimetric analysis. The results show that its optimum synthesis conditions are as follows∶ n(cyanuric chloride)∶n(diamine)∶n(sodium hydroxide)=10∶15∶30,w(cyanuric chloride)∶w(water)∶w(OP-10)=10∶27∶009, the condensation time at 10—15 ℃ being 25 h, the condensation time at 50—55 ℃ being 25 h, and the condensation polymerization time at 90—95 ℃ being 6 h. Under the above conditions, the product yield is 973%, its chlorine content and water solubility are respectively 055% and 021 g·(100 mL)-1, and its thermal stability and charring property are good. The synthesis method without low-boiling organic solvents has some merits such as less environmental pollution, better safety, simpler process and equipment.
