摘要:

使用癸二酸二苯甲酰肼(DSA)与芥酸酰胺物理混合制备复配助剂(DSAE)并使用熔融共混法制备rPA6/DSA复合材料,对复合材料的结晶行为、力学性能进行了详细的分析并与羽毛球网市售产品(BN)进行了性能对比。结果表明,芥酸酰胺的加入并未改变DSA的分子结构,DSA作为异相成核剂能够有效提高rPA6的结晶温度,结晶度,加快结晶速率;而复配后的DSAE通过提高了其在rPA6中的分散性促进这一效果的显著提升;DSA与DSAE的加入均可以有效降低rPA6的摩擦因数和提高其力学性能,且DSAE效果更优。由于相容性的改善,rPA6/DSAE的摩擦因数相较BN下降了28.4 %,缺口冲击强度提高了51.6 %,弯曲强度提高了16 %,复合材料基本达到了耐磨性增强且刚韧平衡,作为羽毛球网用高动态负载产品应用兼具了刚性,韧性和耐磨性,为废弃渔网来源的rPA6在“网对网”途径回收利用开拓了一种新的思路。

Abstract:

In this study, a novel compound additive (DSAE) was developed through physical blending of decanedioic acid bis(benzoylhydrazide) (DSA) and erucamide, which was incorporated into recycled PA6 (rPA6) via melt blending to fabricate high⁃performance composites. Comprehensive characterization revealed that erucamide preserved DSA's molecular structure while DSA functioned as an effective heterogeneous nucleating agent, elevating the crystallization temperature, crystallinity degree, and crystallization rate of rPA6. The DSAE formulation further enhanced these effects through improved matrix dispersion. Both additives significantly improved tribological and mechanical properties, with DSAE demonstrating optimal performance: 28.4 % reduction in friction coefficient, along with 51.6 % and 16 % increases in notched impact strength and flexural strength, respectively, compared to commercial badminton net material. The rPA6/DSAE composite achieved an exceptional balance of wear resistance, stiffness, and toughness, making it particularly suitable for high⁃dynamic⁃load applications. This work pioneers a sustainable “net⁃to⁃net” recycling strategy, transforming waste fishing nets into high⁃value sports equipment materials while establishing a circular economy paradigm for engineering plastics.
