Abstract

The invention discloses a ceramic fiber heat insulation plate. The ceramic fiber heat insulation plate prepared from the following raw materials in parts by weight: 3-5 parts of nano titanium dioxide, 4-9 parts of nano-scale aluminium oxide, 2-8 parts of vanadium pentoxide, 5-7 parts of nano-scale silicon carbide, 35-45 parts of micro-scale silicon carbide, 1-5 parts of a dispersant, 3-4 parts of zirconium latex, 4-8 parts of dolomite powders and 30-40 parts of micro-scale aluminium oxide. The ceramic fiber heat insulation plate disclosed by the invention, on the premise of high temperature resistance, has a high infrared reflection rate, is low in volume density and high-temperature heat conductivity coefficient, and has an excellent heat insulating property, and meanwhile, the ceramic fiber heat insulation plate can be used in the field of high-temperature heat insulation for a long time as a result of excellent bending strength.

Description

technical field [0001] The invention relates to the field of inorganic refractory materials, in particular to a ceramic fiber heat insulation board. Background technique [0002] Thermal insulation is one of the important measures to save energy and ensure sustainable economic development. The development of high-temperature industry has put forward higher requirements for thermal insulation materials, such as high efficiency, energy saving, high strength, low conductivity and waterproof. For this reason, people have been seeking and researching new thermal insulation materials for high-temperature industries with low thermal conductivity, high infrared reflectivity and microporosity. Ceramic fiber is a kind of fibrous lightweight refractory material. The thermal insulation material made of it has the advantages of high temperature resistance, good thermal stability, low thermal conductivity and mechanical vibration resistance. Therefore, it is widely used in machinery, met...
