Description

technical field [0001] The invention relates to a building exterior wall thermal insulation foam ceramic material and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Ceramic materials have many advantages, such as elegant appearance, acid and alkali resistance, high temperature resistance, etc., and are widely used in many fields such as daily necessities, building materials, and mechanical processing. Alumina and zirconia are two common components in ceramic materials. Alumina has excellent properties such as low specific gravity and high temperature resistance. It is widely used in the field of ceramic materials, but its flexural strength and fracture toughness are low; zirconia has Good flexural strength, known as "ceramic steel", but its high specific gravity usually increases the weight of the finished product. The organic combination of zirconia and alumina has attracted more and more attention to the...
