随着废弃电子电器产品的快速增长带来的环境问题日趋严重,废弃印刷线路板的资源化问题一直成为关注的焦点。着重研究了气流分选后得到的废弃印刷线路板非金属粉碎料的资源化再生制板材的可行性,探讨了不同填料粒径、投加量和改性剂下所得复合材料拉伸强度、弯曲和冲击强度的变化。研究表明以马来酸酐接枝聚丙烯（MAH-g-PP）作为改性剂,聚丙烯S700为基体树脂,在粒径范围为0.125～0.3mm的非金属粉碎料添加量为20%的条件下,板材力学性能较优,具有广泛的应用前景。
Electrical and electronic products＇ waste rapid growing caused serious environmental problems.The recycling of waste PCBs had been noticed.The possibility of preparation of the renewable composite panels using non-metallic scraps after air sorting of waste printed circuit boards have been studied and the changes of the tensile strength,bending strength and impact strength of the composite material according to different filler particle size,dosage and modifier has been investigated.The research results showed that using maleic anhydride stem grafting polypropylene（MAH-g-PP） as the modifier,taking polypropylene S700 as the substrate resin,and choosing 20% adding dosage of the 0.125-0.3mm non-metal powder fragments,the plate mechanical properties are superior,and the application prospect is widespread.
