▎ 摘  要

NOVELTY - The utility model claims a radiation-free graphene electric heating film, comprising a protective covering frame and a surface radiation protective pad, the surface radiation protective pad is located right above the protective covering frame inner cavity, and the surface radiation protective pad is provided with an electric heating film main body in parallel; the surface radiation protection pad and the electric heating film main body are placed in the inner cavity of the protective covering frame; the surface radiation protection pad comprises two groups of natural fibre radiation-proof layers arranged in parallel and a synthetic fibre radiation-proof layer located right above the natural fibre radiation-proof layer; the adhesive is filled between the two groups of natural fibre radiation-proof layers; a synthetic resin radiation-proof layer is paved between the synthetic fibre radiation-proof layer and the natural fibre radiation-proof layer. The radiation-free graphene electric heating film not only has radiation-proof performance, reduces the harm of human body, and has high toughness, low manufacturing cost, light weight and good electric heating efficiency and so on.
