Problems solved by technology

The current surface materials have the following disadvantages: the durability of organic coatings and silicon-calcium boards is not good, and they will age and change color after a long time, and lose their decorative effect
However, the above products not only have the defects of high thermal conductivity, low flexural strength, low tensile strength, high water absorption, poor freeze-thaw resistance and post-resistance, but also have extremely poor decorative effects.
However, the existing thermal insulation and decoration integrated lightweight ceramic panels in the market have a high thermal conductivity, generally exceeding 0.065W / (m.k), and the thermal insulation performance is poor. Moreover, the bulk density of the insulation layer of the thermal insulation and decoration integrated panel exceeds 300kg / m3, and the overall material is heavy; the surface is durable. Abrasion resistance and erosion resistance are also extremely poor

Abstract

A high-strength and low-thermal-conduction foamed ceramic, a composite board using the foamed ceramic, and a preparation method thereof. The synthetic raw materials of the foamed ceramic include the following materials: magnesium source, aluminum source, silicon source, zinc source, foaming agent, The foamed ceramic contains magnesium-zinc spinel generated in situ. In this application, the zinc source is used as a catalyst. During the heating process, enstatite and magnesium-zinc spinel solid solutions are first formed. As the temperature increases, enstatite gradually dissolves, and the amount of magnesium-zinc spinel solid solutions gradually increases; During the high-temperature foaming process, the in-situ synthesized magnesium-zinc spinel solid solution crystallites have a pinning effect in the melt, which can reduce the rate of melt viscosity drop, effectively control the abnormal increase of pores, and obtain good uniformity of the pores. , Small-sized foamed ceramics.

Description

technical field [0001] The application relates to a high-strength and low-thermal-conduction foamed ceramic, a composite board using the foamed ceramic and a preparation method thereof. Background technique [0002] The thermal insulation and decoration integrated board is composed of two parts: the surface layer with decorative effect and the thermal insulation layer with thermal insulation effect. The materials of the surface layer are currently commonly used in the following types: calcium silicate board coated with organic coatings such as real stone paint and fluorocarbon paint, colored aluminum board, natural or artificial marble, etc. The current surface materials have the following disadvantages: the durability of organic coatings and silicon-calcium boards is not good, and they will age and change color after a long time, losing their decorative effect. The price of aluminum plate is too high to be popularized. [0003] At present, inorganic thermal insulation mat...
