| 摘 要： | 采用测量极限氧指数(LOI)和锥形量热仪动态燃烧两种方法评价了含硅阻燃剂(SFR-H)与高聚磷酸铵/三聚氰胺氰尿酸盐(APP/MCA)膨胀阻燃体系在聚乙烯基体中的协同阻燃性,并通过红外光谱(FT-IR)、X射线衍射(WAXD)和扫描电镜(SEM)分析炭层结构和成分来研究其协同阻燃机理。研究表明,SFR-H/APP/MCA协同阻燃体系可明显提高聚乙烯的LOI值和降低燃烧热释放速率,具有较好的协同阻燃性,两者在燃烧过程中一起热氧化分解,形成陶瓷状含硅、硼、磷元素的化合物,对表面膨胀炭层起着增强作用,同时也提高了膨胀炭层的热氧稳定性和阻隔性能,从而提高了阻燃效果。

| Abstract: | By the methods of limited oxygen index(LOI),cone calorimeter,Fourier transform infrared spectroscopic(FT-IR),scanning electron microscope(SEM)and wide angle X-ray diffraction(WAXD),the synergistic flame-retarding property and mechanism of a silicon-containing flame retardant(SFR-H)and ammonium phosphate/melamine cyanurate(APP/MCA)intumescent flame-retardant system were studied.The results imply that SFR-H/APP/MCA synergistic flame-retarding system obviously improves the LOI value and decreases heat release ... |
