摘要:

本文研究了以聚磷酸铵(APP)为主阻燃剂,次磷酸铝(AHP)和三聚氰胺氰尿酸盐(MCA)为辅阻燃剂的协效阻燃体系对聚丙烯(PP)阻燃性能的影响。 采用垂直燃烧测试、极限氧指数(LOI)测试、热重分析、锥形量热仪测试、扫描电子显微镜分析等技术手段对所制备的阻燃样品进行了阻燃性能分析。 结果表明:单独添加任一质量分数30%阻燃剂,均不能使PP获得良好的阻燃性能;当阻燃剂总质量分数保持在30%,m(APP):m(AHP):m(MCA)=4:1:1时获得理想阻燃效果,此时阻燃PP的LOI为33%,垂直燃烧测试达到V-0级,热释放速率峰值(PHRR)从765.7 kW/m2降为122.7 kW/m2

Abstract:

In this paper, the synergistic flame retardant system with ammonium polyphosphate (APP) as the main flame retardant, aluminum hypophosphite (AHP) and melamine cyanurate (MCA) as auxiliary flame retardants was investigated for the flame retardant performance of polypropylene (PP). The flame retardant properties of the prepared flame retardant samples were analyzed by vertical burning test, limiting oxygen index (LOI) test, thermogravimetric analysis, cone calorimeter test and scanning electron microscopy. The results show that the addition of 30% mass fraction of any flame retardant alone can not achieve good flame retardant properties of PP. When the total mass fraction of additives is kept at 30%, mass ratio APP:AHP:MCA=4:1:1, the ideal flame retardancy is obtained, LOI of the flame retardant PP is 33%, the vertical burning test reaches V-0 level, and the peak heat release rate (PHRR) is reduced from 765.7 kW/m2 to 122.7 kW/m2.
