Problems solved by technology

Although the use of double-layer helix with fuse short-circuit protection technology and temperature-sensing helix with automatic temperature control technology may solve the problem of thermal safety, but due to the immature technology and high cost, it has not been practically applied at present.
In recent years, new electrothermal film technology and carbon fiber technology have also been popularized and applied, but there are still technical problems to be solved in terms of meeting safety standards, and the price is difficult to be accepted by most people

Embodiment 1

[0034] The specific formula of conductive heating paint is as follows:

[0035]

Natural graphite (size 300 mesh) 250g

Polyurethane 300g acetone 700ml

[0036] Firstly, the polyurethane is fully dissolved in acetone, and then the natural graphite is added and stirred evenly to make a conductive and heat-generating coating. Then above-mentioned coating is brushed evenly to the surface of the cotton cloth of 50cm * 40cm, and the area of ​​coating is 48cm * 38cm, and the thickness of coating is about 40 microns, and solidifies under 70-90 ℃. After fully curing, punch electrode holes on the cotton cloth with conductive heating layer and install copper electrodes. Then, the surface layer and the bottom layer of the conventional carpet are glued on both sides of the cotton cloth with the conductive heating layer to make a composite carpet with conductive heating. Turn on the 220V power supply at an ambient temperature of 0-5°C, and the temperature of ...

[0039] The specific formula of conductive heating paint is as follows:

[0040]

Natural graphite (size 300 mesh) 250g

Polyurethane 300g acetone 700ml

[0041] Firstly, the polyurethane is fully dissolved in acetone, and then the natural graphite is added and stirred evenly to make a conductive and heat-generating coating. Then above-mentioned coating is brushed evenly to the surface of the cotton cloth of 50cm * 40cm, and the area of ​​coating is 48cm * 38cm, and the thickness of coating is about 80 microns, and solidifies under 70-90 ℃. After being fully cured, two electrode holes are drilled on the cotton cloth with a conductive heating layer, and copper electrodes are installed. Then, the surface layer and the bottom layer of the conventional carpet are glued on both sides of the cotton cloth with the conductive heating layer to make a composite carpet with conductive heating. Turn on the 220V power supply at an ambient temperature of 0-5°...

Abstract

The invention relates to a conductive-exothermic composite decorating material, in particular to a conductive-exothermic composite carpet and conductive-exothermic composite wallpaper. The carpet or the wallpaper comprises a surface layer, at least one soft electrothermal material layer, a cemented layer and a bottom layer (a thermal insulating layer or a skid-proof thermal insulating layer). When connected with a power source, the soft electrothermal material layer generates heat, the surface temperature of the carpet or the wallpaper can be controlled, thus simultaneously providing electrical safety and thermal safety that satisfy standards. Simultaneously the conductive-exothermic composite carpet (wallpaper) has simple fabrication technology, and is economical and practical.

Description

technical field [0001] The invention relates to a conductive and heating composite decorative material. More specifically, the present invention relates to a conductive and heating composite carpet and a conductive and heating composite wallpaper. Background technique [0002] The heating elements of existing electric heating carpets include single-layer straight wire type, single-layer spiral type and double-layer spiral temperature-sensitive type; With the development of the plastic industry and chemical fiber industry, the use of single-layer spiral heating wires has solved the problem of electrical safety. But thermal safety issues still exist. Although the use of double-layer helix with fuse short-circuit protection technology and temperature-sensing helix with automatic temperature control technology may solve the problem of thermal safety, but due to the immature technology and high cost, it has not been practically applied yet. In recent years, new electrothermal ...
