摘要
采用质量分数1.5%的光稳定剂苯并三唑、或纳米二氧化钛或二者复配体系与聚苯硫醚(PPS)共混熔融纺丝,制备了共混改性PPS纤维。研究了光稳定剂对共混改性PPS纤维热性能、力学性能及光稳定性能的影响。结果表明:苯并三唑、纳米二氧化钛的加入,对PPS纤维的热稳定性没有影响,对PPS结晶具有促进作用,能显著提高PPS纤维的力学性能,降低PPS纤维颜色变化程度,抑制发色基团的产生,其中苯并三唑含量越高,纤维颜色变化程度越小,纳米二氧化钛含量越高,纤维力学性能增加越大。
The blending modified polyphenylene sulfide (PPS) fiber was prepared from PPS blending with 1.5% photostabilizer by mass fraction containing benzotriazole, nano-titanium dioxide or their composite system via melt spinning process. The effects of the photostabilizer on the thermal property, mechanical properties and photo stability of the blend fiber were studied. The results showed that the addition of benzotriazole and nano-titanium dioxide had no effect on the thermal stability, but promoted the crystallization, considerably improved the mechanical properties of PPS fiber, moderated the color variation degree and inhibited the generation of chromophores. The higher the content of benzotriazole was, the lower the color variation degree of the fiber was. The higher the content of nano-titanium dioxide was, the greater the mechnical properties of the fiber increased.
