Problems solved by technology

[0004] At present, there are many studies on far-infrared heating materials, but most far-infrared heating materials still have many deficiencies.
For example, single-component far-infrared heating materials have the problem of low electric-thermal radiation conversion efficiency, while far-infrared heating materials prepared by multi-components often have problems such as uneven radiation surface temperature and low normal total emissivity.

Abstract

The invention belongs to the technical field of heating materials, and discloses far infrared heating slurry, a heating coating and a preparation method and application of the far infrared heating slurry. The far infrared heating slurry comprises graphene, carbide, film-forming resin and a solvent, the carbide is powdery and has a particle size of 500 nm to 1 [mu] m. The far infrared heating slurry provided by the invention can be uniformly dispersed, has strong stability and has no agglomeration phenomenon; through cooperative use of the components, stronger infrared radiation can be excited, and the far infrared radiance and the surface activity of the slurry are improved; a heating coating prepared from the far infrared heating slurry has relatively high electricity-heat radiation conversion efficiency, uniform radiation surface temperature and high normal total emissivity. The preparation method is simple, efficient and environment-friendly, and can be used for large-scale production.
