| 摘 要： | 采用三氯氧磷、季戊四醇、邻苯二胺为原料合成一种新型磷氮类膨胀阻燃剂四邻苯二胺磷酸酯磷酰氯缩季戊四醇(PDP),通过热重分析(TGA)发现其在700℃氮气氛中具有高达40.8%的残炭率.即使添加20份的炭黑、60份的PDP也能使乙丙橡胶复合材料达到UL-94 V-0级.原位红外光谱揭示残炭中含有丰富的PN键.这归因于PNHC弱碱中氢原子与磷酸酯的相互作用.扫描电镜(SEM)表明燃烧时形成了膨胀炭层.而对乙丙橡胶复合材料的力学性能的研究结果显示增加PDP含量提高了其阻燃性但损害了其力学性能.

| Abstract: | Using phosphorus oxychloride,pentaerythritol and O-diaminobenzene as raw material,a novel intumescent flame retardant pentaerythritol tetra(o-diaminobenzene phosphoramidate)(PDP) was synthesized with high charred residue of 40.8% in N2 at 700 ℃ by TGA.The UL-94 V-0 rating was achieved for EPDM composites with 20 phrs carbon black at the same time by using only 60 phrs PDP.In situ FTIR spectroscopy reveals that PN rich charred residues were formed through the interaction between hydrogen atom in weak base of PNHC and phosphate.SEM characterized the formation of intumescent chars during burning.The mechanical properties of composites were also discussed. |
