中文摘要: 以葡萄糖酸钠,磷酸,三聚氰胺为原料,合成了具备良好阻燃性能的葡萄糖酸磷酸三聚氰胺盐(ATDPDP),通过FTIR,MS对其结构进行了表征,研究了其与聚磷酸铵(APP)以等质量比混合对环氧树脂(EP)阻燃性能和力学性能等方面的影响。结果表明:ATDPDP/APP(1∶1)总量仅为10%时,其氧指数值(LOI)即可达到29.6%,垂直燃烧级别UL-94 V-0;TGA结果表明:质量分数同为10%的ATDPDP,APP,ATDPDP/APP环氧体系,ATDPDP/APP不仅具有更高的残炭量(28.3%),而且能够提高EP的热稳定性;其氧指数测定后残炭表面扫描电镜图(SEM)显示致密、均匀的膨胀炭层;力学性能测试表明ATDPDP/APP对拉伸强度、弯曲强度和冲击强度的影响相对单独使用均减弱。
Abstract:A new phosphorus intumescent flame retardant 6-amino-1,3,5-triazine-2,4 -diaminium 2,3,4,5,6-pentahydroxyhexanoate dihydrogenphosphate(ATDPDP) was synthesized using sodium gluconate, phosphoric acid and melamine as raw materials. The structure was characterized by FTIR and MS. The effects of ATDPDP and APP on flame retardancy, thermal behavior and mechanical properties of epoxy resin (EP) were investigated by limiting oxygen index (LOI) test, UL-94 vertical test, TG and mechanical property test, respectively. The observed data showed an effective flame retardancy with a LOI value of 29.6% and UL-94 V-0 rating when the weight ratio of ATDPDP/APP(1∶1)is only 10% in epoxy resin systems. The morphology of residue after LOI test was investigated by scanning electronic microscopy (SEM), which displayed a well compact swell char layer. The combination system of ATDPDP/APP displayed obviously better ability of char formation and better mechanical properties than acting independently.
