Problems solved by technology

At present, there are mainly two types of thermal insulation materials for building exterior walls. One is the use of foamed ceramic materials. Due to the characteristics of high porosity and low thermal conductivity, foamed ceramic materials can effectively block the transfer of heat and have certain thermal insulation effect, but the large number of pores of foamed ceramic tiles also lead to the common defect of low strength; the other is the use of infrared reflective materials, which can reflect infrared light waves and reduce the absorption of sunlight by building exterior walls, thereby It effectively prevents the surface of the building from absorbing sunlight and plays the role of heat insulation. However, the compatibility between infrared reflective materials and ceramic materials is poor, and it is prone to defects such as cracking and breaking, which restricts its application in thermal insulation ceramics for building exterior walls. application

Abstract

The invention belongs to the technical field of thermal insulation ceramic tiles, and particularly discloses a thermal insulation ceramic tile with a near-infrared light reflection function as well as a preparation method and an application of the thermal insulation ceramic tile. The heat preservation ceramic tile comprises a foaming ceramic layer and a compact layer from bottom to top. The raw materials for preparing the compact layer comprise a base material and a near-infrared light reflecting material, and the initial melting temperature of the base material is 850-900 DEG C. The preparation method comprises the following steps: the raw materials of the foamed ceramic layer are mixed and ground, and spray granulation is carried out to obtain a bottom layer material; the base material and a near-infrared light reflecting material are mixed and ground, and spray granulation is carried out to obtain a surface layer material; after the bottom layer material is flatly paved, the surface layer material is flatly paved on the bottom layer material, and the heat-insulating ceramic tile is prepared by pressing, drying and sintering, so that indoor and outdoor heat transfer can be effectively blocked, and solar radiation can be reduced and outdoor high temperature can be blocked in hot summer; in cold winter, the heat preservation and warming effects are achieved on the building, and therefore energy consumption is reduced.
