▎ 摘  要

NOVELTY - Graphene modified packaging adhesive comprises 70-80 pts. wt. epoxy resin, 5-10 pts. wt. reactive diluent, 1-3 pts. wt. silane coupling agent, 0.1-0.3 pt. wt. defoamer, 15-20 pts. wt. modified amine and 1-2 pts. wt. titanium pigment. USE - Graphene modified packaging adhesive for display screen of electronic paper book. ADVANTAGE - The graphene modified packaging adhesive has long operating time at normal temperature, fast heating and curing characteristics, and low water permeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation graphene modified packaging adhesive which involves (S1) mixing raw materials except modified amine, stirring at a high speed until uniformly dispersing, and grinding the mixture using three-roll machine until the fineness of mixture is ≯ 15 µm to obtain material (A), and (S2) after cooling the material (A) to room temperature, adding modified amine, uniformly stirring at a low speed, and vacuum defoaming.
