Abstract

The invention provides a graphene-containing heating board for building heating and a preparation method thereof. The preparation method includes mixing an aluminum sulfate solution, a silicic acid solution, a hydroxylated inorganic fiber, a graphene oxide and a reducing agent to obtain a graphene-coated inorganic fiber conductive material, then mixing the material with bamboo powder, polypropylene, a coupling agent, a lubricant and color master batch for extrusion to obtain a heating board for heating. According to the preparation method, the hydroxylated inorganic fiber is coated with the graphene oxide, the aluminum sulfate solution and the silicic acid solution and then co-extruded with the bamboo powder and the polypropylene, the aluminum sulfate expands and becomes a sponge-like substance, and the grapheme-coated inorganic fiber is uniformly dispersed to form a network-like heating board.

Description

technical field [0001] The invention relates to the field of building materials, in particular to the preparation of a heating plate, in particular to a graphene-containing heating plate for building heating and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the comfort of the living environment are getting higher and higher, and heating equipment such as air conditioners and heaters cannot meet people's needs. Geothermal heating methods have been generally accepted by consumers, so the requirements for conductive heating materials are getting higher and higher. With the further improvement of environmental protection requirements, the traditional heating methods using oil, gas, and coal consume a lot of energy and generate a lot of pollutants, and the heat conversion efficiency is low. Among them, the field of conductive and heating composite panels is mainly Play the role of conduction hea...
