The invention belongs to the technical field of
electric heating, and particularly relates to a water-based
graphene electrothermal film which comprises a first insulating protective layer, a
graphene heating layer and a second insulating protective layer. The first insulating protective layer and the second insulating protective layer are attached to the top and the bottom of the
graphene heating layer respectively, the graphene heating layer comprises a base material layer, a graphene conducting layer, an insulating layer, a heat preservation layer, a waterproof layer and an
electrode, the outer wall of the base material layer is coated with the graphene conducting layer, and the outer wall of the graphene conducting layer is coated with the insulating layer; the outer wall of the insulating layer and the outer wall of the
electrode are both coated with the heat preservation layer, the outer wall of the heat preservation layer is coated with the waterproof layer, and the left side and the right side of the graphene conducting layer are connected with the
electrode. According to the invention, the main body of the
solvent is water, so that the use of an
organic solvent is reduced to the maximum extent. From the perspective of
environmental protection, the water-based graphene electrothermal film only uses water as a
diluent, is harmless to
human health, does not contain harmful cancerogenic substances in preparation, and is non-toxic and odorless.
