Abstract

The invention relates to an electric conduction and heating functional coating and a preparation method thereof. The electric conduction and heating functional coating is prepared from 50-100 parts ofdeionized water, 55-120 parts of film forming resin, 5-20 parts of electric conduction and heat conduction filler, 1-4 parts of auxiliaries, 15-20 parts of carbon fibers and 5-20 parts of pigment filler. The TiN and flake graphite phase carbon nitride in the prepared electric conduction and heat conduction filler are mutually supported and built, so that the coating has excellent electric and heat conduction effects; in addition, the surface is coated with tin dioxide doped antimony, so that the conductivity of the material can be remarkably improved and the addition of a traditional conductive material is remarkably reduced, and the heating efficiency of the material is improved; the heat-conducting property of the material is further improved by adding carbon fibers, and the finally prepared conductive heating coating is high in safety; heat is transmitted outwards in a heat radiation mode, wherein the heating efficiency reaches 99.4%; therefore, the coating can be widely applied tofloor heating, heating walls, murals and the like and has the advantages of being high in adhesive force, good in flexibility, free of cracking and falling after long-term use, long in service life and the like.

Description

technical field [0001] The invention relates to a conductive and heating functional coating and a preparation method thereof, belonging to the field of functional coatings. Background technique [0002] Heating in winter is one of the main sources of energy consumption in autumn and winter in northern my country, and it also causes serious air pollution problems. How to achieve a balance between people's livelihood, environmental protection and energy conservation has become one of the important issues related to the national economy and people's livelihood. At present, the main heating methods include air conditioners, electric heaters, floor heating, air source heat pumps, gas heating furnaces and electric boilers. Not only the operating cost is relatively high, but also the power consumption is high and the maintenance is troublesome. Therefore, the research and application of heat-generating coatings are of positive significance. [0003] Heat-generating coatings, whic...
