摘　　要：以建筑装饰铝塑复合材料为研究对象,采用高温碱湿法浸出工艺,进行铝塑分离研究。考察了浓度、温度、时间和液固比等对铝浸出过程的影响。试验表明:采用氢氧化钠作为浸出剂浸出含铝废塑料中的铝,并分离塑料是可行的,所用试剂无毒、廉价、易得,其设备简单。This study with engineering plastic materials for research object using wet leaching construction decoration aluminum- plastic composite process, aluminum- plastic separation study on various factors, including concentration, temperature, time and the liquid -solid ratio on the influence of aluminum leaching process. Through tests can draw the conclusion： adopting sodium hydroxide as leaching agent, separation of aluminum and plastic is feasible, the reagent non - toxic, cheap, easy.
