摘　　要：水性漆清洗废溶剂的处理,是目前行业内的一个难题,处理成本高,技术难度大。为了解决该问题,研究发明了膜分离材料再生技术,通过膜分离再生技术将涂装喷涂过程中和喷涂设备换色清洗过程中产生的废溶剂进行分离再生,将75%的水重新回到生产线再次使用,将涂料提取出来合成再生涂料。从而达到物质回收再利用的效果。该技术在奥迪生产线实际应用两年,性能可靠,单条15万辆涂装生产线降低成本超过500万元。At present,the disposal of waste solvent for water-borne paint cleaning is a problem of the automotive industry that is difficult to overcome for high disposal cost and high technological difficulty.In order to solve this problem,membrane separation material&recycling technology was invented,which separated and recycled the waste solvent produced in painting and color change and cleaning of painting equipment by membrane separation&recycling technology.In this process,75%of water was recycled and reused in the painting line,while the paint was extracted to make renewable paint,the material was thus recycled and reused.The technology has been applied to Audi painting line for 2 years with reliable performance,the cost reduction of the 150,000 units painting line exceeded 5 million yuan.

关 键 词：水性漆清洗废溶剂 膜分离 再生涂料
