▎ 摘  要

NOVELTY - Black adhesive comprises 2-8 pts. wt. colorant, 100-200 pts. wt. polyurethane resin and 10-150 pts. wt. solvent. The colorant includes reduced graphene oxide and polydopamine, where the polydopamine is attached to surface of the reduced graphene oxide. USE - The black adhesive is useful in preparation of first adhesive layer for aluminum-plastic film (claimed). ADVANTAGE - The black adhesive: utilizes reduced graphene oxide has excellent thermal conductivity, which realize excellent bending effect, endows black soft package material including black adhesive with excellent drawing performance, enhances heat conduction during battery use, improves heat dissipation, improves safety and prolongs battery life; and has strong peel strength and puncture strength, excellent high temperature and high humidity resistance and formability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for aluminum-plastic film, comprising matte layer, heat-resistant resin layer, first adhesive layer, metal layer, second adhesive layer, and thermoplastic resin layer stacked in sequence, where the surface of metal layer is a corrosion-resistant layer and the first adhesive layer is formed by black adhesive.
