Embodiment 1

[0027] Embodiment 1 A three-layer co-extrusion preparation method of a graphene composite heating film.

[0028] Such as Figure 1 to Figure 4 As shown, a graphene composite heating film is sequentially attached to the first polyester film 1, graphene / polyester composite film 3, and the second polyester film 2, and the two sides of the graphene / polyester composite film 3 are Metal foil strip 4, the metal foil strip 4 on both sides forms the metal foil strip counter electrode, and a single graphene composite heating film can also include polyester edge banding 5, polyester edge banding 5 is 1-5cm wide, polyester edge banding 5 It is formed by laminating the first polyester film 1 and the second polyester film 2 . A three-layer co-extrusion preparation method of a graphene composite heating film according to the present invention uses two raw materials, polyester particles and graphene / polyester composite particles, respectively, through "melting→extrusion→casting→stretching→ ...

Abstract

The invention belongs to the field of graphene heating film preparation, and in particular, relates to a three-layer coextrusion preparation method for graphene composite heating films. A machining method for a first-layer polyester film and a third-layer polyester film comprises ester polymerization-melting-extrusion-casting-stretching-thermal shaping; a machining method for a middle-layer graphene/polyester composite film with metal foil strips comprises graphene/polyester compounding-melting-extrusion-casting-stretching-implantation of the metal foil strips-cutting-thermal shaping-rolling;in the thermal shaping process, two sides of the graphene/polyester composite film with the metal foil strips are covered on the first-layer polyester film and the third-layer polyester film; and through rolling, the graphene composite heating films are formed. The graphene composite heating films are not contacted with resistance layer by layer, so that the demands in various application fields can be met.

Description

technical field [0001] The invention belongs to the field of graphene heating film preparation, in particular to a three-layer co-extrusion preparation method of graphene composite heating film. Background technique [0002] With the rapid development of graphene preparation technology, the application of graphene is becoming more and more mature. Among them, the graphene heating film technology is energy-saving and environmentally friendly, which meets the requirements of a series of energy and environmental protection policies such as the contemporary coal-to-electricity transformation, and is an excellent alternative to traditional home improvement plumbing technology. [0003] However, the preparation process of the current mainstream graphene composite heating film is relatively simple. After the graphene is prepared into a composite slurry, it is coated or printed on the surface of the substrate and dried, pasted with metal foil strips on the electrode, and rolled into...
