Electrothermal composite ceramic brick and preparation method thereof
The invention discloses an electrothermal composite ceramic brick and a preparation method thereof. An electrothermal coating layer, a guiding-out wiring electrode, a coating insulation packaging waterproof layer and an application foaming ceramic layer coat an unglazed surface of a ceramics substrate in order. The electrothermal coating layer coats the unglazed surface of the ceramics substrate in an electrothermal slurry form, the electrothermal slurry permeates the green body of the ceramics substrate, and the penetration depth is less than the thickness of the ceramics substrate and more than 0.5mm. Because of the penetration, the electrothermal coating layer of the electrothermal composite ceramic brick is combined with the ceramics substrate tightly, a surface heating mode is achieved, the thermal efficiency is high, normal and safe usage can be achieved under a voltage of 24-380V, the heating power is 90-120w/m<2>, and the temperature of the ceramics substrate can reach 18-50 DEG C through a temperature control device. The insulation packaging waterproof layer and the foaming ceramic layer outside the electrothermal coating layer can prevent heat from outward transmission effectively, heat loss is lowered, and the whole safety and reliability of the ceramic brick are raised.
