Problems solved by technology

After the carbon crystal heating plate is laid, the service life is short, the heating plate is easy to age, has strong electromagnetic radiation, and there are many joints at the same time, it is easy to have uneven heat dissipation and uneven heating and cooling
In addition, there are still many research institutions conducting research on heating cables, but the general heating cables cut metal heating wires or non-metallic heating wires to a certain power and then connect them to the power wires. The insulation of the connection between the heating wire and the power wire cannot be guaranteed, and there will be electromagnetic radiation after power-on
In the prior art, carbon fibers are also used as electric heating wires to make floor heating or electric blankets, but the heat attenuation of carbon fibers is serious, and the heating temperature cannot be guaranteed, which consumes energy.
[0004] The Chinese patent application number is CN201710336496.3, which discloses a carbon fiber heating cable. The heat attenuation of carbon fiber is serious, and the heating temperature cannot be guaranteed, which consumes energy.

Description

technical field [0001] The invention belongs to the field of heating elements, and in particular relates to a graphene polymerized nano-energy heating wire and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the living environment of urban and rural residents has been greatly improved, and more and more families have replaced conventional air-conditioning equipment with floor heating that is more comfortable to use, environmentally friendly and energy-saving. Floor heating is the abbreviation of radiant floor heating. It uses the whole ground as a radiator, heats the whole ground evenly through the heat medium in the radiant layer of the floor, and uses the heat storage and heat radiation of the ground itself to conduct from bottom to top to achieve The purpose of heating. [0003] Existing floor heating includes traditional water floor heating, heating cables, electric heating films, and carbon cryst...
