Problems solved by technology

[0003] Most of the electric heating plates in the prior art are electric heating plates using graphite and carbon black as conductive substances. Because of their weak electrical conductivity and small adhesion, the following disadvantages exist in the carbon crystal electric heating plates in the prior art: 1. ) The adhesion of the electric heating layer is small, which makes the sealing of the electric heating plate poor; 2) The thermal stability of the electric heating plate is lacking, and the resistance will change with the increase of use time; 3) The surface temperature difference of the electric heating plate is large, exceeding the temperature difference within seven degrees Celsius Require

Abstract

The invention belongs to the technical field of floor heating construction engineering, and particularly provides a graphene electric heating plate for ground heating. The graphene electric heating plate mainly comprises an upper epoxy resin sheet, a graphene heating layer and a lower epoxy resin sheet, wherein the upper epoxy resin sheet, the graphene heating layer and the lower epoxy resin sheet are sequentially overlapped. The front end and the rear end of the lower epoxy resin sheet are respectively provided with a second metal sheet and the second metal sheet is positioned on the surface of the lower epoxy resin sheet that is closer to the graphene heating layer. The front end and the rear end of the upper epoxy resin sheet are respectively provided with a front wire hole and a rear wire hole. Inside the front wire hole, an electric wire electrically connected with the second metal sheet at the front end of the lower epoxy resin sheet penetrates through the front wire hole. Inside the rear wire hole, an electric wire electrically connected with the second metal sheet at the rear end of the lower epoxy resin sheet penetrates through the rear wire hole. The invention correspondingly provides a method for producing the graphene electric heating plate for ground heating. The prepared graphene electric heating plate for ground heating is safer, more reliable, better in heat stability, better in adhesive force and the like.
