| 摘 要： | 利用废印刷线路板非金属粉、木粉和聚氯乙烯制备复合材料，研究了复合材料的物理力学性能.结果表明:添加40目(0.35 mm)粒径非金属粉的非金属粉-木塑复合材料的各项性能整体优于添加20目(0.83 mm)粒径的复合材料；随着复合材料中40目粒径非金属粉替代量的增加，复合材料冲击强度、静曲强度整体呈下降趋势，内结合强度总体呈上升趋势， m(非金属粉)∶m(木粉)为30∶20时，静曲强度和内结合强度分别为31.74 和2.10 MPa，满足相应的国家标准和行业标准；40目粒径非金属粉-木塑复合材料的静曲模量随着非金属粉和木粉比率的增加先上升后下降，在m(非金属粉)∶m(木粉)为15∶35时达到最大值(2 853 MPa)；24 h吸水厚度膨胀率和24 h吸水率分别优于硬质纤维板国家标准和地板基材用纤维板行业标准要求值.

| Abstract: | The composites of nonmetallic powder from waste printed circuit boards(NM-PCBs),wood and PVC were prepared,and the physical and mechanical properties of the nonmetal-wood-plastic composites(NM-WPC) were studied.The results show that the performance of 40-NM-WPC is superior to that of 20-NM-WPC as a whole.With the increasing addition of 40 mesh size non-metallic powder,the impact strength and bending strength of 40-NM-WPC decrease,but internal bond strength increases in general.When the ratio of the non-meta... |
