Embodiment 1

[0030] Such as Figure 1-2 As shown, a graphene far-infrared electric heating flexible cloth comprises an upper waterproof cloth 1 and a lower waterproof cloth 2, a graphene heating layer 3 is arranged between the upper waterproof cloth and the lower waterproof cloth, and the graphene heating layer two ends are woven with The guide line area 4, copper wire or silver wire with a diameter of 0.05-0.1mm is used as the braiding material in the guide line area; the conductive silver paste layer 5 is coated on the guide line area;

[0031] The graphene heating layer uses glass fiber cloth 6 as a carrier, and a graphene conductive film 7 is attached to the surface of the glass fiber cloth; the graphene heating layer is bonded to the upper waterproof cloth and the lower waterproof cloth through an adhesive.

[0032] A wire 8 is provided at one end of the guide line area, and the wire is connected to the conductive silver paste layer through a connecting device 9 . In this embodiment,...

Embodiment 2

[0040] A kind of production technology of graphene far-infrared electric heating flexible cloth, comprises the steps:

[0041] S1. Use electronic glass fiber cloth as the carrier (preferably 50-150g / m 2 Electronic glass fiber cloth), uniformly dip-coat a layer of graphene conductive paste on the glass fiber cloth (except for graphene conductive paste, conductive paste containing graphite or carbon particles can also be used), and then heat through 120 ~ 150 ℃ The drying tunnel is dried, so that the graphene conductive paste forms a graphene conductive film in a dry film state, and a graphene heating layer is obtained;

[0042] S2. Cut the graphene heating layer prepared in S1 according to the required size, use a seaming machine on the two long sides of the cut graphene heating layer, and use silver wire or copper wire as the wire weaving guide line area;

[0043] S3. Coating a layer of conductive silver paste on the area of ​​the guide line obtained in S2 and drying to form...

Abstract

The invention relates to a graphene far infrared electric heating flexible cloth and a production process thereof, the flexible cloth comprises an upper waterproof cloth layer and a lower waterproof cloth layer, a graphene heating layer is arranged between the upper waterproof cloth layer and the lower waterproof cloth layer, two ends of the graphene heating layer are woven with diversion line areas, and copper wires or silver wires are adopted as weaving materials in the diversion line areas; a conductive silver paste layer is coated on the diversion line area; the graphene heating layer adopts glass fabric as a carrier, and a graphene conductive film is attached to the surface of the glass fabric; the graphene heating layer is bonded with the upper waterproof cloth and the lower waterproof cloth through an adhesive; the heating layer is particularly suitable for being used as an infrared heating source of physical therapy wearable equipment, far infrared physical therapy instruments, electric heating carpets, electric heating plates and the like, the heating layer adopts an independent unit, the electronic glass fabric serves as a carrier, thermal deformation caused by taking plastic as the carrier is avoided, conductive slurry can be thoroughly dried, meanwhile, random cutting and packaging are facilitated, and the service life of the heating layer is prolonged. And the method is suitable for various application scenes.

Description

technical field [0001] The invention belongs to the technical field of electrothermal materials, and in particular relates to a graphene far-infrared electric heating flexible cloth and a production process thereof. Background technique [0002] With the development of science and technology, far infrared physiotherapy products have been widely used in my country and even in the world. Far-infrared physiotherapy products are mainly used in physiotherapy eye masks, physiotherapy neck protectors, physiotherapy knee pads, physiotherapy belts, physiotherapy insoles, physiotherapy beds and steam rooms, etc. [0003] Early physiotherapy products all used carbon fiber heating wire as the infrared heating core, and released far infrared rays through electric heating. The advantage of carbon fiber heating wire is that it can be coiled irregularly, and can be used as various special-shaped heating devices. The disadvantage is that the heat decay of carbon fiber heating wire is fast, ...
