Ceramic tile with heating function and preparation method thereof

Abstract

The invention discloses a ceramic tile with a heating function. The ceramic tile is prepared by fitting a ceramic tile layer with a ceramic tile base layer with a cavity, wherein the cavity is located on one side of the fitting surface; the cavity is filled with an insulating layer, a heating layer and an insulating sealing heat conducting layer overlapped in turn from bottom to top; a metal electrode and a temperature sensor are arranged in the heating layer. According to the ceramic tile disclosed by the invention, a cavity for filling a heating function composite layer is arranged on one side of the fitting surface between the ceramic tile layer and the ceramic tile base layer, and the layer structure of the composite layer is further limited; by adding a near-infrared inorganic heat reflecting layer, the heat emitted by the heating layer is efficiently transferred to the ceramic tile layer and effectively prevented from being transferred downward, and the heating efficiency and thermal insulation property of the ceramic tile are greatly improved. The invention also discloses a preparation method of the ceramic tile, which has the advantages of simple preparation technology, low production cost and high operability and facilitates industrial large-scale production.

Description

technical field [0001] The invention relates to the field of functional architectural ceramics, in particular to a ceramic brick with heating function and a preparation method thereof. Background technique [0002] Ceramic tiles have become a commonly used home decoration material due to their excellent properties and unique decorative effects, and are widely used in floor and wall decoration. In recent years, some ceramic tiles that can be heated have appeared, which can heat the room when the weather is cold, and have a large heat dissipation area, which has great application prospects. Ceramic tiles with heating function usually embed electric heating materials such as electric heating wires and electric heating tubes under the ceramic tile substrate, and realize the heating of the ceramic substrate by means of electric heating and heat conduction. However, the contact area of ​​the heating wire is small, the overall heating efficiency is very low, and the life of the he...

Problems solved by technology

However, the thermal conductivity of the foamed ceramic layer is about 0.15 watts / (m·degree), and only relying on the foamed ceramic layer as the insulation layer has poor insulation effect, easy to lose heat, and low thermal efficiency.
