▎ 摘  要

NOVELTY - The utility model claims a vacuum heat-insulating plate, comprising a core material, a barrier film and a getter, the barrier film is coated on the outer surface of the core material, the outer surface of the barrier film is coated with a layer of insulating coating composed of alpha-phase Al3O2 nano-powder and hybrid graphene aerogel mixed material, the surface of the barrier film is added with a modified graphene coating, so as to improve the heat insulation performance of the refrigerator, reduce the refrigerator energy consumption.
