摘要

中文摘要: 以聚磷酸铵(APP)为酸源

利用ABS/PA6合金中PA6为炭源对ABS/PA6合金进行膨胀型阻燃研究，探讨了不同成炭协效剂与APP复配对合金阻燃性能的影响，这些成炭协效剂包括季戊四醇笼状磷酸酯（PEPA），热塑性酚醛树脂（TPPFR），环氧树脂（EP）和分子筛4A。结果表明，PA6具有较好的成炭作用

当APP含量为25%时，阻燃合金体系的极限氧指数可达30，UL-94测定达V-1级别，APP含量为35%时，UL-94测定达V-0级别。而以5wt%的季戊四醇笼状磷酸酯（PEPA）或环氧树脂（E-44）与20wt%APP复配

或以3 wt%分子筛4A与22wt%APP复配都可以大大提高体系的阻燃性能性和高温下的残炭量

使阻燃体系氧指数达到30以上

UL-94测定达V-0级别. SEM形貌分析显示体系燃烧表面都形成了膨胀、均匀、致密的炭层结构。

Abstract

Abstract:Abstract：The effect of the intumescent flame retardant system on ABS/PA6(80/20)alloys was studied．The system was compounded with APP for acid sources and PA6 in ABS/PA6 alloys for carbon sources. The effect of different synergistic charring agents on the flame retardancy of the ABS／PA6 alloys was investigated

including pentaerythritol caged phosphate (PEPA)

thermoplastic phenolic resin (TPPFR)

epoxy resin (E-44) and Zeolite 4A. The results show that PA6 has the good effect of charring

When the wt% of APP is 25%

the limiting oxygen index (LOI) value was found to be 30 and the UL-94 measure be class V-1. When the wt% of APP is 35%

the UL-94 measure were found to be class V-0. The ABS/PA6/APP has the better flame retardancy when a little of synergistic charring agents (PEPA

E-44 or Zeolite 4A) were be added to the compound . The expansion

uniform

dense carbon layer formed on the surface of the complex after burning was observed by scanning electron microscopy (SEM).
