Abstract

The invention discloses a preparation method of a heat-conducting insulating coating layer for an electric floor heating sheet. The preparation method comprises the following steps: mixing a water-borne epoxy resin matrix and nanoscale heat-conducting particles to prepare an insulating heat-conducting coating, then coating the surface of a polypropylene base heating sheet subjected to plasma surface treatment with the insulating heat-conducting coating through a spraying process, and drying and curing to obtain an insulating coating layer; the insulating coating layer not only plays an insulating role, but also has excellent heat dissipation performance. On the premise of ensuring the safe use of the polypropylene base heating sheet, the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the field of water-based thermally conductive and insulating epoxy coatings, in particular to the technical field of a method for preparing a thermally conductive and insulating coating for electric floor heating. Background technique [0002] With the improvement of living standards, indoor heating methods in winter are also improving. In addition to the traditional heated kang, radiators, plumbing, and air conditioners, there is also a new type of floor heating sheet that can automatically adjust the temperature. The floor heating material is banburyed together with thermally conductive carbon black and polypropylene resin, mixed evenly with the woven metal copper mesh, and then rolled into a double-roller open mill to obtain a polypropylene-based electric floor heater. The floor heating sheet is conveniently cut into various shapes, which is convenient for interior decoration construction; it can generate heat after being c...
