Graphene electric heating cloth and manufacturing process thereof

Abstract

The invention provides graphene electric heating cloth and a manufacturing process thereof. The graphene electric heating cloth comprises an upper base fabric, a lower base fabric, a power supply, anoverheat protection module, an electronic temperature control module and a heating time control module, wherein the upper base cloth comprises base cloth, a far infrared radiation conductive slurry layer, a graphene nano material layer, an electronic-grade glass fiber yarn layer, a modified polyacrylonitrile fiber layer and a PTFE film, and a heating space is formed between the upper base cloth and the lower base cloth. According to the invention, heat energy is generated through mutual impact and friction between graphene carbon molecules of the graphene nano material layer under the initiation and excitation of power supply electricity, a large amount of infrared radiation is generated, the infrared radiation is radiated through the far infrared radiation conductive slurry layer, large-area uniform and low-temperature heating can be achieved, the far-infrared radiation function can make people feel more comfortable, blood circulation is improved, and abnormal temperature rise can beprevented through the overheating protection module, the electronic temperature control module and the heating time control module.

Description

technical field [0001] The invention relates to the field of graphene, in particular to a graphene electric heating cloth and a manufacturing process thereof. Background technique [0002] Graphene is a two-dimensional carbon nanomaterial in which carbon atoms form a hexagonal honeycomb lattice with sp2 hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. Among the electric heating products on the existing market, different electric heating products have different technical content, and also have different characteristics and application fields. Many electric heating products are roughly divided into several types, namely metal resistance heating wire, printing ink type, Ultra-metal sheet type, carbon fiber type and functional polymer electric heating ty...

AI Technical Summary

Problems solved by technology

[0003] The heating element in the above electric heating products can work normally at a temperature of 150-600 degrees, but once out of control occurs, it is very easy to cause accidents and fires, and there are great hidden dangers in safety. At the same time, some electric heating cloths are in the process of folding It is easy to damage the electric heating circuit and cause the loss of electric heating functionality. Some electric heating cloths also have disadvantages such as unstable heating performance, large leakage current, uneven heating, and limited power.
