Abstract

The invention provides a heat insulation ceramic tile for an external facade of a building and a preparation method thereof. The preparation method comprises the following steps: grinding waste glass,refining the ground waste glass, and carrying out spray spheroidizing at a high temperature to prepare glass microspheres; mixing the glass microspheres with hydrotalcite, lead oxide, alumina, pigment and water, and carrying out ball milling to obtain glaze; spraying the glaze into mist under the action of a pressure by compressing air with a spray gun, and applying the mist to the surface of a pre-burned ceramic tile; feeding the ceramic tile into a roller kiln for quick burning for 3-5 min at 1200-1400 DEG C, and cooling to obtain the heat insulation ceramic tile. The glass microspheres inthe glaze and the hydrotalcite form a reflecting layer after being burnt quickly, so that the heat of the sun is converted into infrared rays with a wavelength of 5-10 [mu]m for reflection, the heat is prevented from entering the building, and the reflecting layer has a continuous heat insulation effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to improving the heat insulation of facades through reflective layers, and in particular to a heat-insulating ceramic brick for building facades and a preparation method. Background technique [0002] With the development of the economy and the improvement of people's material living standards, urban and rural buildings have increased rapidly, and the problem of building energy consumption has become increasingly prominent. Statistics show that the energy consumption of the construction industry accounts for 40% to 50% of the total energy consumption of the whole society. "Sustainable development" has become the development strategy of many countries in the world. Experts put forward the concept of "green building". Green building is a building that utilizes resources effectively. In recent years, with the increasingly tense global energy situation, countries around the world have ...
