摘要
En 中文
日益增长的气候变化担忧推动了可持续复合材料中使用木粉等废弃物资源。然而,将木粉掺入丙烯腈-苯乙烯-丙烯酸酯(ASA)树脂中常因界面结合力弱而导致韧性降低。本研究旨在通过添加聚烯烃弹性体(POEs)并采用母料(MB)工艺来提升木粉/ASA复合材料的力学性能。复合材料通过两步挤出法制备,并进行了拉伸和伊佐德冲击测试。采用马来酸酐接枝的乙烯-丁基丙烯酸酯(EBA-g-MA)与MB工艺的优化配方,使冲击强度提高了50.5%(86.45 J/m),断裂伸长率提高了243.6%(13.71%),同时保持了拉伸强度。这些结果表明,通过选择相容剂并结合MB工艺,为平衡韧性、冲击强度和强度提供了有效途径。该方法为开发用于汽车和户外应用的耐用、可持续ASA基木复合材料提供了实用指导。
