  • 摘要: 针对新型多元共挤出复合材料存在的次表层木塑复合材料(WPCs)与核层实木界面结合强度低,使用过程中易发生界面剥离导致复合材料力学性能和使用寿命降低的问题,本文采用聚氨酯热熔胶胶膜(TPU)和乙烯-丙烯酸共聚物胶膜(EAA)包覆单板层积材(LVL)与塑料/木塑制备了高界面结合强度的多元共挤出复合材料(Co-WPCs-LVL)。研究结果表明:TPU和EAA均能有效提高WPCs层与核层LVL的界面结合强度,界面结合强度随着胶膜熔点的增加而逐渐降低,其中引入TPU (熔点80℃)和EAA (熔点95℃)的WPCs与LVL界面结合强度相对于未处理组分别提高了27倍、56倍。EAA可以显著提升WPCs与LVL的界面耐水性能,Ⅱ类浸渍实验后界面未发生剥离。证明胶膜在高温的挤出作用下能够渗入LVL表面与羟基(—OH)发生反应,同时能与聚乙烯分子链混合扩散形成牢固的界面结合。经过人工加速老化后,胶膜处理组的WPCs与LVL仍具有较高的界面结合强度,界面结合强度剩余率随着熔点的增大而增大,其中EAA(熔点135℃)实验组表现出最好的界面耐久性,界面结合强度剩余率达到97.25%。
