Description
Technical Field
The invention belongs to the field of architectural ceramics, relates to a glaze, and particularly relates to a light-operated heat transfer glaze.
Background
At present, the ceramic market has the characteristics of high-grade, artistic and personalized requirements, functional products and the like, and decorative materials with health and high taste become the mainstream of consumption.
The far infrared ray is also called long wave infrared ray, and its wavelength range is from 5.6 micrometers to 1000 micrometers. The far infrared heating technology utilizes far infrared rays emitted by a hot object source to irradiate a heated material, so that internal molecules and atoms generate heat energy through resonance after the material absorbs the far infrared rays, thereby achieving the purpose of heating. The technology can improve the heating efficiency and save energy.
CN 111333324A discloses a far infrared overglaze and a far infrared ceramic tile. The mineral composition of the far infrared overglaze comprises: by mass, 50-60% of far infrared feldspar powder, 10-20% of albite, 5-10% of kaolin, 5-15% of zirconium silicate, 2-5% of calcined kaolin and 5-10% of alumina. The far infrared overglaze adopts far infrared feldspar powder as a far infrared material, and has good high temperature stability and low radioactivity. The far infrared long material realizes the far infrared function of the ceramic tile by adjusting the formula of the overglaze, and the far infrared emissivity is more than 0.87.
CN112010672A discloses a ceramic tile with far infrared composite air purification function and a preparation process thereof. Comprises a ceramic green brick and a glaze layer, wherein the glaze layer is prepared from far infrared powder and anion powder, and the far infrared powder comprises calcium oxide and nanometer Y 2 O 3 -MgO far infrared powder; the nano Y 2 O 3 The outer surface of the MgO far infrared powder is wrapped and sintered by the negative ion powder; the nano Y 2 O 3 MgO far infrared powder is adsorbed on the surface of calcium oxide particles; the calcium oxide and nanometer Y 2 O 3 The mixing ratio of the weight parts of-MgO far infrared powder is 1:3-4; the weight portion ratio of the far infrared powder to the negative ion powder is 1:2-3. The ceramic tile with the far infrared composite air purification function can activate the activity of negative ion inducing substances in the negative ion powder, so that more negative ions are induced to purify air.
Disclosure of Invention
In order to solve the technical problem, the application provides a light-operated heat transfer glaze, which can adjust the heating value of a ceramic tile according to the on-off of ambient light under the condition of matching with a heat source, and has excellent mechanical properties.
In order to achieve the technical effect, the invention adopts the following technical scheme:
the invention provides a light-control heat transfer glaze, which comprises the raw materials of potassium feldspar, albite, magnesium oxide modified nano tin oxide and nano yttrium oxide.
In the invention, a system of tin oxide and yttrium oxide can emit far infrared rays, and the magnesium oxide modified tin oxide has stronger capability of emitting far infrared rays under the illumination condition and has very low capability of emitting far infrared rays under the dark condition. The ceramic tile prepared by the glaze can be applied to areas which are weak to natural light, such as toilets and kitchens. When the area is not used, the area is generally in a non-light state, and the tile hardly conducts heat at the moment. Because the far infrared emission performance of glaze can attenuate along with the live time, this kind of ceramic tile that can receive light-operated can only be conducted heat when this region is used, has not only satisfied the requirement of the ceramic tile performance that generates heat, has prolonged the life of ceramic tile simultaneously.
According to the invention, the glaze can be matched with the blank body with a heat storage function, when no illumination exists, because the glaze almost has no function of releasing far infrared rays, the heat stored in the blank body is slowly released to the outside, when illumination exists, the function of releasing far infrared rays by the glaze is enhanced, and the heat is promoted to be emitted to the space through far infrared waves, so that the ceramic tile has the self-adaptive heating function. The ceramic tile can also be matched with external heat sources such as floor heating and the like, when no light is emitted, the glaze almost does not release far infrared rays, and the ceramic tile only plays a role in heat conduction; when the glaze is illuminated, the glaze releases far infrared waves at the moment, so that the heat of an external heat source can be promoted to be dissipated to the environment, and the temperature of the environment is promoted to rise.
