【摘要】：以三聚氯氰、吗啡啉和乙二胺为原料,通过分子设计采用一锅法合成新型三嗪类大分子成炭剂(CFA-m),采用红外光谱、固体核磁共振、元素分析和热分析等对合成大分子成炭剂的结构和热性能进行表征。将CFA-m与次磷酸铝(AHP)复配,用于阻燃聚乳酸(PLA),研究了CFA-m/AHP复配阻燃剂对PLA阻燃性能、热稳定性能和热释放性能的影响。结果表明,CFA-m/AHP对聚乳酸有良好的阻燃作用。当CFA-m/AHP的质量比为3∶1,总添加量为20%时,阻燃PLA的极限氧指数(LOI)达到32%,通过UL94 V-0级。
[Abstract]:A new type of triazine macromolecular carbonizing agent (CFA-m) was synthesized by one-pot method using cyanuric chloride, morphine and ethylenediamine as raw materials. Infrared spectroscopy (IR) and solid nuclear magnetic resonance (NMR) were used to prepare CFA-m. The structure and thermal properties of the synthesized macromolecular carbonizing agents were characterized by elemental analysis and thermal analysis. CFA-m was mixed with aluminium hypophosphate (AHP) for flame retardant polylactic acid (PLA). The effects of CFA-m / AHP composite flame retardant on the flame retardancy, thermal stability and thermal release properties of PLA were studied. The results showed that CFA-m / AHP had a good flame retardant effect on polylactic acid. When the mass ratio of CFA-m / AHP is 3: 1 and the total addition amount is 20, the limiting oxygen index (loi) of the flame-retardant PLA reaches 32 and passes through UL94 V-0.
