Problems solved by technology

The high-temperature viscosity of traditional solar-reflecting ceramic glazes is too low, and they are usually used on ceramic slabs. Ceramic slabs will not produce foaming or release gas during firing, and the glaze layer is less affected, while the foam Most of the ceramics are open-cell formulas, and the closed porosity is not high. Using ceramic glazes with solar reflection properties for foam ceramics is prone to glaze defects such as pinholes and foaming.

Abstract

The invention belongs to the technical field of ceramics, and discloses a foamed ceramic with high sunlight reflection performance and heat insulation and a preparation method thereof. The foamed ceramic comprises a foam layer, a compact layer and a functional glaze layer from bottom to top, the foam layer comprises the following components: glass powder, potassium-sodium feldspar, borax and a foaming agent; the functional glaze layer comprises the following components: mica and tungsten trioxide. Through combination and component adjustment of the foam layer, the compact layer and the functional glaze layer, the problems that the closed porosity of a conventional foam ceramic formula system is not high and the high-temperature viscosity of a ceramic glaze with sunlight reflection performance is too low are solved, so that the foam ceramic has the advantages of heat preservation and heat insulation of a base material and sunlight reflection of a glaze surface; glaze defects such as pinholes, foaming and the like cannot be generated, and meanwhile, acid and alkali corrosion resistance and antifouling performance are good.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a foam ceramic with high solar reflection performance and heat insulation and a preparation method thereof. Background technique [0002] At present, the increasing energy consumption has caused many environmental problems, such as global warming, water pollution, air pollution and so on. According to statistics, the energy consumption of residential and commercial buildings is increasing steadily, surpassing the energy consumption of industry and transportation. Therefore, reducing building energy consumption has become a research hotspot. [0003] The main source of building energy consumption is the high energy consumption of air conditioning due to the high heat transfer coefficient of traditional building materials. Therefore, the development of new building materials for building energy saving and thermal insulation has become the key to reducing building ene...
