Method for separating and recycling materials of each component in waste printed circuit board

The invention discloses a method for separating and recycling the materials of each component in a waste printed circuit board (PCB), and is characterized by subjecting the waste PCB to vacuum pyrolysis, shear breakage, screening classification, gravity separation and medium-temperature calcination, so that all materials of components in the waste PCB can be separated and recycled to obtain organic pyrolytic oil, metal mixtures and glass fiber; wherein, the recycled organic pyrolytic oil can be used as fuel oil or chemical materials, the recycled metal mixtures can be used as metallurgical materials, and the recycled glass fiber can be used as glass fiber processing materials or fillers, thereby achieving the purpose of recycling all resources. The method of the invention can effectively separate and recycle all materials of components in the waste PCB, and has the characteristics that the technological method is simple, feasible, efficient and pollution-free. Therefore, the invention is of great social, economic and environmental benefits.
