Novel nano-carbon-fiber heating floor and preparation method thereof

Abstract

The invention provides a novel nano-carbon-fiber heating floor and a preparation method thereof. The preparation method comprises the following steps: (1) placing nano polyacrylonitrile fibers prepared by electrostatic spinning in a roasting oven, performing heat treatment by using air as a medium, and performing carbonization treatment under nitrogen environment so as to obtain carbonized nano polyacrylonitrile fibers; (2) stirring plant protoplasm fibers and a cationic surface active agent under a closed condition and normal temperature till a uniform mixture is obtained, adding the carbonized nano polyacrylonitrile fibers and nano graphite powder in the mixture, stirring the carbonized nano polyacrylonitrile fibers, the nano graphite powder and the mixture at a high speed, and preparing sheet type flexible macromolecule materials by a hot-pressing technology; (3) fixing metal-sheet electrodes at both ends of the sheet type flexible macromolecule materials by a silver solution so as to form a conductive heating layer; and (4) shearing a solid-wood layer, an insulation layer, the conductive heating layer, a temperature control layer, another solid-wood layer and a surface treatment layer with appropriate sizes from bottom to top, and performing combination so as to form the nano-carbon-fiber heating floor.

Description

Technical field: [0001] The invention belongs to the technical field of electric heating floors, and in particular relates to a novel nano-carbon fiber heating floor and a preparation method thereof. Background technique: [0002] As we all know, my country's heating methods have undergone five generations of transformations: central heating, small boiler heating, heating cable heating, carbon crystal heating sheet heating, and floor direct heating heating, and the heating floor is the leading heating method of the fifth generation. The heating floor is a heating core layer directly added in the middle of the wooden floor, which can directly generate heat after power on, realizing the combination of floor and floor heating. Compared with the previous heating methods, the heating floor has fast heating, high heat conversion rate, time-sharing and zone-controlled temperature control, and can also emit far-infrared waves that are beneficial to the human body. It has a good heal...

Problems solved by technology

The carbon fiber heating plate is implanted with carbon fiber inside the high-strength insulating material as a heating element. When it is energized to generate heat, under the excitation conditions induced by electricity, through the Brownian motion of microscopic particles on the irregular conductor surface, the cushion layer will be continuously impacted and rubbed. Converted into heat energy, it has the advantages of planar heating, shielding ultraviolet rays, natural, moisture-proof, corrosion-resistant, anti-oxidation, no open flame, no peculiar smell, no pollution, long life, etc. It can be directly laid and applied to indoor heating systems, with simple structure and convenient construction , but the application in our country is not yet mature
