▎ 摘　　要

NOVELTY - Producing graphene heating film slit and extrusion coating composite comprises subjecting substrate corona treatment, coating graphene slurry with slit mold, performing drying process, gluing the copper strip, performing glue solidifying, processing film corona, and extruding coating composite. USE - The method is useful in field of composite material, preferably in graphene coating multi-use roller coating or blade coating mode. ADVANTAGE - The method: has one-step continuous production process; adjusts the size specification according to the production need; also has high production capacity, and small personnel proportion; maximizes full embodying efficiency; and improves adhesiveness of graphene slurry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene heating film slit and extrusion coating composite production line. DESCRIPTION OF DRAWING(S) - The drawing shows a front part plan view of the graphene heating film slit and extrusion coating composite production line.
