摘要

将PA6与辐敏剂三聚氰酸三烯丙酯(TAC)共混后造粒纺丝

再经氮气气氛下的γ辐射

研究了辐照交联对锦纶6熔滴性能的影响。在100kGy的辐照剂量下锦纶6的凝胶含量达到了63.23%

此剂量下的防熔滴效果最好

熔滴数由燃烧时间内的13滴减少到6滴。从粘度测试、现象分析、热降解行为以及动态燃烧性能等方面对熔滴减少的原因进行了探讨

结果表明:辐照交联提高了燃烧时的熔体粘度

促进了热降解残留物含量的增多

提高了热释放速率峰值

在固相成炭方面影响了熔滴的滴落。

Abstract

Effect of irradiation cross-linking on anti-dripping property of PA6 fibers with the presence of TAC was studied. At the dose of 100kGy in N2 atmosphere

the gel content arrived at 63.23% where the flame drops decreased from 13 to 6. The reason for anti-dripping was investigated from the view of flaming phenomena

thermo gravimetric analysis and dynamic flammability test. Irradiation cross-linking strengthened the melt viscosity

increased the residue char at 600℃ and the peak of heat release rate

slowed down the flame drops for the char-forming in condense phase.
