摘要
采用双酚A-双(磷酸二苯酯)分别与聚磷酸铵和纳米二氧化硅复配制备新型无卤阻燃环氧树脂(EP)材料。通过氧指数、垂直燃烧和锥形量热研究环氧树脂复合体系的阻燃性能。通过热失重和电镜扫描分析对比不同阻燃体系的热分解过程及燃烧炭层结构,推测阻燃机理。
The effect of flame retardant composed of bisphenol - A his（diphenyl） phosphate ester（BDP） and ammonium polyphosphate or nano -SiO2 on epoxy resin is investigated by limiting oxygen index（ LOI）, horizontal and vertical firing and cone calorimetry. The results indicate that BDP/SiO2 is more effective on the flame retardancy of epoxy resin than BDP/APP. The flame retardant mechanism is deduced by analyzing the thermal stability and the morphology of the residue of the flame retarded EP.
