preparation example Construction

[0038] refer to Figure 1 to Figure 3 As shown, a single-sided spray-coated conductive film and a preparation method thereof include a film body 1, and the film body 1 includes a base film 2, a graphene layer 3 positioned on one side of the base film 2, and a graphene layer positioned on one side of the graphene layer 3. The sealing layer 4 of the film body 1 is made by the following device: including a film outlet 5, a film processing device 6, a film roll shaft 7, and a number of rolls connected to the film processing device 6 below the film processing device 6 Roller 8, the film outlet 5 is arranged on one end of the film processing device 6 and is connected with the roll film shaft 7 of the base film 2, and the film roll shaft 7 is set on the other end of the film processing device 6 for making the finished film The film body 1 is rolled up, the base film 2 is located above the roller 8, one end of the roller 8 is connected to the film outlet 5, and the other end is conne...

specific Embodiment

[0053] In actual use, the base film 2 passes through the film outlet 5, and the smooth guide film roller 601 in the first film processing assembly 61 rolls the base film 2, compacts the base film 2, and the rough rolling roller 602 rolls The base film 2 is roughened to increase the adsorption effect. The graphene nozzle 603 sprays the graphene glue, and the smoothing scraper 607 behind the graphene nozzle group 603 ensures that the sprayed graphene glue is uniform in thickness, and the ultraviolet laser emitter 604 emits Laser to dry the sprayed graphene glue;

[0054] The second film processing assembly 62 processes the processed base film 2 again, repeats the above processing steps, continues rolling, spraying graphene glue, laser drying, and further compacting to increase the adhesion effect of graphene glue, so that Graphene glue is not easy to fall off;

[0055] The hot pressing roller 605 rolls the film main body 1 , and the cold pressing roll 606 rolls the processed fi...

Abstract

The invention discloses a single-side spraying conductive film and a preparation method thereof, the conductive film includes a film body, the film body includes a base film, a graphene layer on one side of the base film, a sealant layer on one side of the graphene layer, A film body is manufacture by that following device: include a film outlet, film treatment unit, A film roll shaft and a rollerunde that film processing apparatus and in rolling connection with the film processing apparatus, The film processing apparatus includes a film processing assembly including a first film processing assembly and a second film processing assembly, the first film processing assembly and the second film processing assembly including a smooth film guide roller, a rough rolling roller, a graphene nozzle and an ultraviolet laser emitter connected in sequence. The manufacture method of the invention is simple in technology, meets the requirement of products with high adhesion, sprays graphene glue solution twice and roll twice, makes the film body compact and firm, and greatly improves the electric conductivity of the conductive film.

Description

technical field [0001] The invention relates to the field of conductive films, in particular to a single-sided spray-coated conductive film and a preparation method thereof. Background technique [0002] A conductive film is a thin film having a conductive function. As a material for forming a conductive circuit on a substrate, conductive paints (sometimes called conductive pastes, conductive inks, etc.) containing conductive fillers such as silver powder and copper powder are known. for practical purposes. Generally, after the conductive paint is coated on the substrate by printing and other methods, the conductive film is made by sintering. [0003] Graphene is a new type of two-dimensional carbon material with a honeycomb structure composed of a single layer of carbon atoms. Graphene has excellent electrical conductivity, the electrical conductivity is 1.6 times that of copper; graphene has excellent transmittance to near-infrared, visible light and ultraviolet light, a...
