摘要
以9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)与三聚氰胺(MEL)为原料制备了一种含磷、氮以及苯环的新型阻燃剂(DOPO-MEL)。通过X射线衍射仪、傅立叶红外光谱仪与电喷雾阳离子质谱分析验证了其结构,并将其与聚磷酸铵(APP)复配阻燃聚丙烯(PP)。结果表明:DOPO-MEL与APP具有良好的协同阻燃效应。将30%(质量分数,其中DOPO-MEL∶APP=1∶2)的膨胀型阻燃体系添加于PP时,复合材料的极限氧指数(LOI)为29.4%,且能够通过UL-94测试V0级别。
A novel flame retardant,containing phosphorous,nitrogen and benzene rings,was prepared with 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide（DOPO）and melamine（MEL）.The X-ray diffraction（XRD）,Fourier transform infrared（FT-IR）spectra and the electrospray ionization mass spectrometry（ESI-MS）were introduced to analyze the chemical structure of DOPO-MEL.An intumescent flame-retardant system（IFRs）composed of DOPOMEL and ammonium polyphosphate（APP）was applied to polypropylene（PP）.Results revealed that DOPO-MEL and APP had an excellent synergistic effect.Loaded with 30 wt% of IFRs（DOPO-MEL∶APP=1∶2）,PP/IFRs composite showed promising flame retardancy,UL-94 test passed V0 rating and LOI value was up to 29.4%.
