Abstract

The invention provides a novel carbon fiber hot-core floor based on a modified carbon fiber hot-core layer. A preparation method comprises the specific operation steps that long fibers of carbon fibers are cut off and stirred to be broken, and carbon fiber short fibers to be modified are obtained; the carbon fiber short fibers to be modified are placed in a low-temperature plasma apparatus to be subjected to plasma treatment, and activated carbon fiber short fibers are obtained; the activated carbon fiber short fibers are added into a hydrochloric acid solution containing aniline, slow stirring is conducted, an initiator is added, reacting is conducted at room temperature, and the carbon fiber short fibers are taken out, washed and dried to obtain polyaniline-coated modified carbon fibers; the polyaniline-coated modified carbon fibers are placed in paper making equipment or non-woven fabric manufacturing equipment, and modified carbon fiber paper is obtained or a carbon fiber non-woven fabric is obtained; the modified carbon fiber paper or carbon fiber non-woven fabric is composited with an electrode and an insulating material phase to obtain the based modified carbon fiber hot-core layer, and the modified carbon fiber hot-core layer is composited with a wooden layer phase to obtain the carbon fiber hot-core floor based on the modified carbon fiber hot-core layer.

Description

Technical field: [0001] The invention belongs to the technical field of electric heating floors, and in particular relates to a carbon fiber heating core floor based on a modified carbon fiber heating core layer. Background technique: [0002] With the continuous improvement of people's living standards, people's requirements for the living environment are getting higher and higher. It is not only necessary to meet the basic living conditions, but also to create a comfortable, comfortable and intelligent living environment, and the indoor environment is required to meet the temperature, Humidity, lighting, wind speed, pollutant concentration and other aspects are controlled within a certain range. The adjustment of the indoor environment needs to be realized by HVAC equipment. At present, low-temperature hot water is generally used in China to transport indoor heat dissipation equipment through the outdoor pipe network to form a heating system. However, it is really difficul...
