Problems solved by technology

[0002] At present, the existing heating film materials mainly include carbon fiber, carbon printing material, metal heating wire material, etc., and their common characteristics are that the heating body is relatively thick, has high hardness, cannot be flexibly bent, and has no elasticity. Will break and fail when bent at small angles
[0003] In addition, the conventional heating film will paste a layer of PI or PET material as an insulating layer on the surface of the heating material, which leads to easy delamination of the insulating layer and the conductive layer, and the processing technology is complicated.

preparation example Construction

[0031] The embodiment of the present invention also provides a method for preparing a conductive leather material, which includes: after coating the conductive slurry on a film-forming mold, drying it at a temperature of 80-190°C to form a conductive structure; One side of the film mold is coated with non-conductive slurry, and dried at a temperature of 80-190° C. to form a non-conductive layer.

[0032] It should be noted that the preparation method of the conductive leather material provided in the embodiment of the present invention is to form a film through two coatings, and the conductive material finally obtained is conductive on one side and non-conductive on the other, which avoids the process of processing the insulating layer in the later stage; The surface and the non-conductive surface are fused and combined, not easy to delaminate, and the insulation effect is reliable, which is suitable for popularization and application; due to the use of polyurethane film format...

Embodiment 1

[0040] This embodiment also provides a preparation method of conductive leather material, which comprises the following steps:

[0041] Mix graphene powder, N,N-dimethylformamide and polyurethane uniformly to obtain conductive paste, wherein the weight ratio of graphene powder, N,N-dimethylformamide and polyurethane is 10:100:100. Mix N,N-dimethylformamide and polyurethane evenly to obtain a non-conductive slurry, wherein the weight ratio of N,N-dimethylformamide and polyurethane is 1:1.

[0042]After coating the conductive paste on a planar release film, dry it at 80°C for 2 hours to form a conductive film with a thickness of about 1um, and evenly coat the non-conductive paste on the dried conductive film. After drying at a temperature of ℃ for 2 hours, a non-conductive layer with a thickness of about 1 um is formed. The conductive material formed by the fusion of the conductive film and the non-conductive film is peeled off from the release film.

Embodiment 2

[0044] This embodiment also provides a preparation method of conductive leather material, which comprises the following steps:

[0045] Mix copper powder, butanone and polyurethane uniformly to obtain conductive paste, wherein the weight ratio of copper powder, methyl ethyl ketone and polyurethane is 60:80:100. Mix toluene and polyurethane uniformly to obtain non-conductive slurry, wherein the weight ratio of toluene and polyurethane is 0.8:1.

[0046] After coating the conductive paste on a flat release film, dry it at 190°C for 1.5 hours to form a conductive film with a thickness of about 1000um, and evenly coat the dry conductive film with non-conductive paste. After drying at 190°C for 1.5h, a non-conductive layer about 3000um thick was formed. The conductive material formed by the fusion of the conductive film and the non-conductive film is peeled off from the release film.

Abstract

The present invention discloses a conductive leather substance and a preparation method thereof, and relates to the technical field of conductive substances. The conductive leather substance comprisesa non-conductive layer and a conductive structure located at one side of the non-conductive layer; the non-conductive layer is a film-shaped structure formed after drying of non-conductive slurry, and the conductive structure is formed by drying conductive slurry. The conductive leather substance is conductive at one surface and is insulated at the other surface to avoid the later processing processes of an insulation layer, the non-conductive layer and the conductive structure are fused and combined to allow stratification not to be easily generated. The preparation method of the conductiveleather substance are subjected to twice coating to form the non-conductive layer and the conductive structure on a film formation die, and therefore, the method is simple and practicable and is suitable for industrialized application.
