【摘要】 采用PPS/PA6共混的方法来改进大直径PPS单丝的力学性能。探讨了共混体系的结构对共混单丝力学性能的影响,并与相关聚合物单丝进行了对比分析,同时研究了共混单丝的耐酸碱性能。结果表明:PA6的加入能有效地改善PPS单丝的力学性能,提高了单丝的拉伸强度和勾结强度,增加了PPS单丝的韧性。同时,PPS/PA6共混单丝能保持PPS单丝原有的耐酸性、耐碱性能。更多还原

【Abstract】 PPS and PA6 were blended to improve the mechanical properties of the large diameter PPS monofilaments.The influence of the structure of the blends on the blending monofilaments,the comparative analysis with relevant polymer monofilaments and the acid and alkali resistance were studied.The results demonstrated that: the mechanical properties of the PPS monofilaments was improved.The tensile strength and the collaboration strength of the monofilaments were increased.The toughness of the PPS monofilaments was increased.Simultaneously,the acid resistance and alkali resistance of the PPS monofilaments were retained in the PPS/PA6 blending monofilaments.更多还原
