NOVELTY - The method involves taking two single corrugated surface metal plate strip materials. The graphene surface of a graphene coating layer (3) is coated on the surface of the two single metal plate strips material to form a graphene coating layer. The two single steel plate strips are stacked on the same surface. The corrugation surfaces of the two of the single steel sheet metal sheet strip material is matched. The two steel sheets metal sheet strips opposite to each other is meshed. USE - Preparation method for composite plate strip material. ADVANTAGE - The method enables improving bonding strength and yield of composite board strip material, and improving strength of the composite plate strip, plasticity and conductivity. The method allows the corrugated surface of the metal plate strip to be matched with the ripple before rolling stack assembly so as to form contact uniform interface at a joint interface, so that mechanical meshing has better structure, thus improving interface bonding degree, and hence inhibiting metal composite plate from warping along a rolling direction, improving plate quality and improving coating amount of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a preparation method for composite plate strip material. 3Graphene coating layer 4Composite metal plate strip
