Abstract

The invention provides a barrier layer for being arranged on the surface of a sintered mold for preparing foamed ceramics, the composition of the barrier layer includes quartz sand, zirconia, aluminum oxide, carbide and nitride, wherein the carbide It includes one or more of silicon carbide, tungsten carbide and boron carbide, and the nitride includes one or more of silicon nitride, boron nitride and tungsten nitride. The barrier layer is used to be arranged on the surface of a sintered mold for preparing foamed ceramics, and is characterized in that the components of the barrier layer include quartz sand, zirconia, aluminum oxide, carbides and nitrides, wherein the carbides include One or more of silicon carbide, tungsten carbide and boron carbide, and the nitride includes one or more of silicon nitride, boron nitride and tungsten nitride. The invention also provides a sintering mold and a preparation method of the sintering mold.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a barrier layer, a sintering mold and a preparation method thereof. Background technique [0002] Foamed ceramic (foamed ceramic) material is a porous material with high temperature characteristics. It has excellent properties such as low thermal conductivity, light weight, high hardness, corrosion resistance, wear resistance, water seepage resistance and easy regeneration. It can be widely used It is used in many fields such as environmental protection, industrial and civil construction, national defense industry, petrochemical industry, municipal construction, underground engineering, road traffic, bridges and tunnels, biological planting, refrigeration industry and thermal equipment. [0003] Most of the foamed ceramic materials currently on the market are prepared in molds or kiln furniture at high temperatures, and use shelving boards that mainly suppor...
