NOVELTY - The utility model claims a graphene-based electric heating film driven by low voltage, comprising a substrate insulating layer, a middle heating layer containing graphene and an outer sealing insulating layer; the middle heating layer is coated between the substrate insulating layer and the outer sealing insulating layer; the upper surface of the middle heating layer is adhered with 3 parallel conductive electrodes by conductive adhesive; 3 conductive electrodes are distributed on the middle heating layer at equal intervals, the substrate insulating layer is made of temperature-resistant insulating material; the middle heating layer is made of conductive paste formed by mixing graphene, single-wall carbon nano-tube and conductive carbon black; the outer sealing insulating layer is made of resin with flame-retardant, heat-resistant insulating function; The advantage is that it adopts the middle fire wire, two sides of the circuit design of the zero line, which not only can improve the heating efficiency, and the safety is more reliable.
