Abstract
The invention discloses a high-temperature energy-saving coating material for metal, belonging to an organic and inorganic compound characterized by components. Feldspar, bentonite, corundum, SiC, 2-amino-2-methyl-1-propanol, Fe2O3, ZrO2, Cr2O3 and a high-temperature adhesive are taken as raw materials to be mixed in certain proportion to form the composition. The high-temperature energy-saving coating material for metal has quite high radiation rate in the range of very high temperature, and good thermal stability, can be used for the surfaces of various metals, does not produce oxidative decomposition under the long-term action of high temperature heat load, does not reduce radiation ability, improves the heat-absorbing performance of pipe walls and operational capability of equipment, and has remarkable energy-saving effect.
Description
Technical field
The present invention relates to a kind of coating, especially relate to a kind of high-temperature energy-saving coating material for metal.
Background technology
Far-infrared technique is extensive Ying Yu every field, and more application mainly concentrate on the high emission performance of utilizing material, and are less for the absorption heat energy performance study that utilizes material.
High-temperature coatings is many based on SiC in the market, and employing spraying method, because SiC high conduction performance, play energy conservation object, but adopt of heating installation such as industrial boiler and civilian cooker contained metallic substance such as aluminium, iron, silicon, copper more, because conduction efficiency there are differences between SiC and these materials, feasible to contain SiC material at high temperature energy-saving coatings effect not fairly obvious.
As 87017902 patent disclosure technology, SiC has quite high heat-radiating properties in very high temperature range, and satisfactory stability, be a kind of good high-temperature coatings matrix, but SiC is under elevated temperature heat load long term operation state, can oxygenolysis, influence coating work-ing life.
2-amino-2-methyl-1-propanol solution is mainly used in carbon dioxide absorption, does not appear in the high-temperature energy-saving coating material at present.
Summary of the invention
The present invention solves high-temperature coatings SiC problem of oxidation, improves high-temperature energy-saving coating material and uses conductive performance between the product, adopts 2-amino-2-methyl-1-propanol solution to absorb the heat absorption capacity that improves this coating with the thermal radiation atmospheric carbon dioxide simultaneously.
In order to realize above-mentioned technical problem, the present invention has adopted following scheme:
A kind of high-temperature energy-saving coating material for metal, belonging to the composition is the organic and inorganic mixture of feature.Said composition is by feldspar, wilkinite, brown corundum, SiC, 2-amino-2-methyl-1-propanol, Fe
2O
3, ZrO
2, Cr
2O
3, high-temperature agglomerant is raw material, it is as follows to mix the proportioning that it is characterized in that preparing each component by a certain percentage, feldspar 20%, wilkinite 5%, brown corundum 10%, SiC16%, 2-amino-2-methyl-1-propanol 0.2%, Fe
2O
315%, ZrO
210%, Cr

35%, high-temperature agglomerant is a raw material 19.8%.The vibration mill respectively to each component by the graininess requirement less than 3000 orders, particle diameter is less than 5 microns, standard operation is passed through mixing machine then and is mixed, adding high-temperature agglomerant at last is that raw material 19.8% stirs.
Operation preparation high-temperature energy-saving coating material has following characteristics like this:
1) refractory temperature 〉=1300 degree
2) hemisphere full wave absorption rate 〉=0.95
3) utilize nanotechnology treatments, make that metal ingredient and nonmetal composition thorough mixing are even in the coating, metal ingredient is basic identical with the material that uses product in the coating simultaneously, reaches the conducting effect of superelevation, and makes coating strengthen at the sticking power of metal pipe-wall
4) can adopt spraying or use this high temperature energy-saving material with the method for making material mixing such as boiler, cooker
5) reach work-ing life more than 2.5 years
Embodiment
A kind of high-temperature energy-saving coating material for metal takes by weighing 20 kilograms of feldspars, 5 kilograms of wilkinites, 10 kilograms in brown corundum, SiC16 kilogram, 0.2 kilogram of 2-amino-2-methyl-1-propanol, Fe
2O
315 kilograms, ZrO
210 kilograms, Cr
2O
35 kilograms, high-temperature agglomerant is 19.8 kilograms of raw materials.
The vibration mill respectively to each component by graininess requirements less than 3000 orders, particle diameter is less than 5 microns standard operations, passes through mixing machine then and mixes, and adds high-temperature agglomerant at last and stirs for 19.8 kilograms, tests its viscosity, generally range of viscosities 15-30.
With the specialty spray gun, be sprayed at the boiler of different model, its effect is as follows: boiler thermal output improves 5%, and exert oneself and improve 20-35%,
Adopt country to announce the disclosed detection method of GB4653-84, through the experiment of 600h ultrahigh-temperature, coating does not have efflorescence, and is flawless, and nothing is peeled off, and the normal direction total emissivity is 0.85-0.95.
