Beschreibung
Zusammenfassung:	The invention provides a multi-layer co-extrusion electromagnetic shielding fluoroplastic electric insulation corrugated pipe and a preparation method thereof. The pipe comprises an insulating layer and an electromagnetic shielding layer, the wall thickness of the insulating layer is 0.1-2 mm, and the wall thickness of the electromagnetic shielding layer is 0.1-3 mm. The insulating layer is an inner insulating layer and/or an outer insulating layer, the inner insulating layer is located on the inner side of the electromagnetic shielding layer, and the outer insulating layer is located on the outer side of the electromagnetic shielding layer. The preparation method comprises the following steps: respectively putting an insulating master batch and an electromagnetic shielding master batch into corresponding extruders, carrying out multi-layer co-extrusion to extrude a fluoroplastic straight pipe, continuously forming a fluoroplastic straight pipe which is not completely cooled in a corrugated pipe equipment mol
