Description
Technical field
The present invention relates to a kind of high temperature furnace energy-saving coating material, more particularly, to a kind of infrared high emissivity coating of width warm area
Material and preparation method thereof.
Background technology
High temperature kiln is widely used in national product and scientific research every field, is belonging to high energy-consuming industry product, in the energy
Very big share is occupied in total amount consumed.The heat utilization rate of particularly most of industrial high temperature furnace is generally relatively low, has very big
The energy saving space.High temperature furnace inwall coating high-emissivity material is to realize a kind of effective way of energy-conservation, high emissivity coating
The emissivity of inboard wall of burner hearth can not only be improved, improve the distribution of burner hearth heat ray, increase Secondary Emission heat energy utilization, improve energy
Source utilization ratio, and the anticorrosive, anti-thermal shock of inboard wall of burner hearth refractory material and resistance to can be strengthened by special coating design
The performances such as flame impingement, play protection high-temperature burner hearth, the effect of prolongation kiln service life.Both at home and abroad high emissivity coating is entered
Go numerous studies, and developed multiple product and be used widely.For example, have document open report many oxide base and
Silicon carbide-based infrared high-emissivity coating material formula and preparation method thereof (Ouyang De just etc., " infrared radiation coating technology of preparing
With technique study ", steel research, June calendar year 2001, the 3rd phase, the 41-44 page).Although existing high emissivity coating has necessarily
Energy-saving effect, but also there are problems, such as coatings emissivity is obvious with the dependence of wavelength (using temperature), i.e. coating
Can only operate in certain warm area just to there is high emissivity and play energy-conserving action, and can not have in the range of very wide warm area
High emissivity performance；Use at high temperature, the emissivity of coating easily decays, affect service life and energy-saving effect；Coating with
Matrix combine undesirable, using easy to crack after a period of time, peel off, come off.Additionally, high performance energy-saving coating material is prepared into
Originally all compare high with price, Industrial Stoves large area use cost is higher.These deficiencies all constrain high emissivity energy-saving coatings
Application on high temperature kiln.

The purity of fiber can be used for different refractory temperatures, highest can more than 1700 DEG C of heatproof, and according to alumina fibre material
Density difference can be used for refractory surface or the heat-insulation layer of high temperature furnace, and therefore, alumina fibre refractory material is as a kind of light-weight refractory
Material obtains increasing popularization and application.However, alumina fibre refractory material infrared emittance at high temperature is relatively low, make
Relatively low using heat utilization rate for high-temperature burner hearth refractory surface, particularly loose loose structure intensity is very poor, and surface is very easy to
Scaling-off, have a strong impact on the use as burner hearth refractory surface.
