The utility model relates to a composite pipe of copolypropylene plastic and copper metal pipe, which comprises a copper pipe, a PPR plastic and an adhesive layer and an anticopper agent. Adhesives, anti-copper agent layer is arranged between the copper tube and PPR plastic tube layer, and the one-time hot melt bonding co-extrusion composite becomes the overall structure, the "one-step method" extrusion molding process is as follows:
1. Copper pipe surface is handled;
2. Preheating;
3. Extrudes antimetal adhesive layer and PPR plastic layer respectively by the composite extrusion machine outside copper pipe, form the Cu-PPR pipe;
4. Composite die;
5. Cooling system;
6. check back finished product.
