摘　　要：介绍了国内外对废塑料基复合材料回收技术的相关现状,根据废塑料基复合材料的特点采用机械粉碎、解离(大型破碎、中碎、粉碎解离)、高压静电分选的方法回收废塑料复合材料,回收金属(铝等)的纯度达99%以上;金属(铝等)回收率达99%以上;回收塑料的纯度达96%以上,接近甚至超过国外同类技术的水平。在回收过程中不使用任何化工原料,不使用水,不排放任何污染物。The relevant technologies for recycling waste plastic matrix composites at home and abroad were introduced. According to the characteristics of waste plastic matrix composites, mechanical crushing, dissociation （large breaking, breaking, crushing dissociation）, high-voltage electrostatic separation methods were used for recycling composite materials. The purity of recovered metal （such as aluminum） was more than 99 %,metal （aluminum） recovery was more than 99 %,too.The purity of recycled plastic was more than 96 %. These data were close to or above the level of similar foreign technology. The recycling process did not use any chemicals and water, did not discharge any pollutants.
