Heating and heat conduction integrated carbon nanotube cement fine mortar geothermal floor

Abstract

The invention provides a heating and heat conduction integrated carbon nanotube cement fine mortar geothermal floor which comprises a first gradient structure and a second gradient structure. The first gradient structure is a cement fine mortar solidification layer reinforced by high-dosage carbon nanotubes, the second gradient structure is provided with a carbon nanotube coating, and the carbon nanotubes have excellent electric conduction and heat conduction performance, have a good heating effect after being electrified, and play a role of an electric heater. The second gradient structure isconnected with a power source and emits heat, and the heat is uniform conducted into a room through the first gradient structure. The carbon nanotubes are added into fine cement mortar, so that the fine cement mortar heat conduction floor is provided, the carbon nanotube self-heating coating is attached to the bottom of the cement mortar floor by utilizing the excellent electric conductivity of the carbon nanotubes, finally the heating and heat conduction integrated cement fine mortar geothermal floor is formed, the structure is simple, the heat transfer effect is good, and the compressive strength is good.

Description

technical field [0001] The invention relates to the field of cement mortar, in particular to a cement fine mortar geothermal floor added with carbon nanotubes, which has the function of heat conduction and heating. Background technique [0002] At present, floor heating equipment has entered thousands of households, and heating floors have also received widespread attention. Floor heating uses the whole or part of the ground as a heat dissipation surface, and makes its surface temperature rise to 24-26 ° C, mainly in the form of radiant heat (about 61.25% of the total heat) to dissipate heat indoors, which is a kind of conventional convection radiator Different new heating methods. Heating floors are a form of underfloor heating. Generally, the electric heating material is arranged in the floor, and the purpose of heating is achieved by energizing the electric heating material in the floor, so that the floor is heated. Existing heating floors are usually composed of multi...
