摘要

利用锥形量热仪（CONE）和热重分析（TGA），并结合极限氧指数（LOI）和UL-94垂直燃烧测试方法对核（PSt/OMMT）-壳（PBA）结构纳米复合粒子（CSN）填充聚丙烯（PP）-乙烯-醋酸乙烯酯共聚物（EVA）复合材料及加入无卤复配阻燃剂制备的PP-EVA/CSN/聚磷酸铵（APP）/层状氢氧化镁铝（LDH）复合阻燃材料的阻燃性能及热降解行为进行了研究。结果表明，添加10%（wt）CSN可以提高PP-EVA复合材料的阻燃性能，且PP-EVA复合体系燃烧时的热释放速率、有效燃烧热减少，热稳定性增强。CSN与APP/LDH产生阻燃协同作用，使复合阻燃材料的阻燃性能、热稳定性能进一步提高。

Abstract

By using Cone Calorimeter(CONE) and thermogravimetric analysis (TGA)

limiting oxygen index (LOI) and vertical burning test (UL-94)

the flame retardance and thermal degradation behaviors of polypropylene(PP)-ethylene-vinyl acetate copolymer(EVA) composite filled core-shell nanoparticles(CSN) with polystyrene (PSt)/organophilic montmorillonite (OMMT) as core and poly(butyl acrylate) (PBA) as shell and its flame retarded composites prepared of PP-EVA/ammonium polyphosphate(APP)/layered double hydroxide(LDH) by additions of non-halogen mixture as flame retardants were studied. The results showed that adding 10%(wt) CSN could improve the flame retardancy of PP-EVA composites

decrease the heat release rate and the effective heat of combustion

increase thermal stability of PP-EVA composite. CSN had a little better synergistic flame retardant effect with APP/LDH

which can further built up flame retardancy and thermal performance.
