The thermal insulation composite board has the advantages of light weight, small occupied space, high shock resistance and good thermal insulation effect, is relatively economical and practical and convenient to mount and also meets the environmental protection requirement.
Description
Technical field
The present invention relates to a kind of heat-insulating composite plate.
Background technique
Various countries pay attention to the research to the thermal insulation thermal insulation board of high-temperature service and heat distribution pipeline always; The thermal insulation thermal insulation board made from the mineral fiber flooring is mainly studied by the U.S.: Russia serves as the research and development emphasis with expanded perlite and slag wool mainly: Japan is main with thermal insulating materials such as development rock wool, little calcium silicate mainly then, and China's high-temperature service and heat distribution pipeline adopt by single refractory brick, heat-resisting mould material or layer of fibers (wad, fibrofelt) usually.In order to reach the effect of insulation, the thickness of general heat-insulating composite plate is relatively thick, and shared space is bigger, and weight is heavier.For the high temperature processing system, because it is bulky, thus be not easy to move, and this heat insulation structure is not easy to a little less than installation, the shock resistance.Single in addition with zirconium oxide plate etc., cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of heat-insulating composite plate, not only in light weight, the institute of this heat-insulating composite plate take up space for a short time, and shock resistance is strong, and is economic and practical, and insulation is effective, meet environmental protection requirement.
Heat-insulating composite plate of the present invention comprises the mesosphere, is bonded in the outer of mesosphere one side and is bonded in the nexine of mesosphere another side that said mesosphere is an aluminium sheet, and said skin is the zirconium plate, and said nexine is a ceramic beaverboard.
Described heat-insulating composite plate, the thickness in its said mesosphere are can be at 45-55mm, and said outer field thickness is can be at 35-45mm, and the thickness of said nexine is can be at 35-45mm.
Described heat-insulating composite plate, its said skin is bonded in the one side in mesosphere through high temperature resistant adhesive, and nexine also is bonded in the another side in mesosphere through high temperature resistant adhesive.
Described heat-insulating composite plate, its said zirconium plate is the heat-insulating fiber plate that contains zirconium oxide, silica etc.
Described heat-insulating composite plate, its said aluminium sheet are the heat-insulating fiber plates of salic, silica etc.
Described heat-insulating composite plate, its said ceramic beaverboard are ceramic fiber composite adiabatic wads.
Described heat-insulating composite plate, its said high temperature resistant adhesive are high temperature resistant inorganic salt binders.
Zirconium oxide fiber board is that unique ability satisfies the docrystalline refractory fibrous material that uses for a long time under the superhigh temperature oxidizing atmosphere more than 1600 ℃.Because high-melting-point (2700 ℃), not oxidation and other high temperature good characteristic of ZrO2 material itself; Make the ZrO2 fiber have serviceability temperature and better heat-shielding performance than existing refractory fiber kind is higher on the Domestic market; And high temeperature chemistry stable in properties, corrosion-resistant, anti-oxidant, anti-thermal shock, non-volatile, pollution-free are the most high-grade undisputed refractory fibrous materials.Performance advantage: 1. serviceability temperature is for the highest.Maximum operation (service) temperature is up to 2200 ℃, even to 2500 ℃ of fiber shapes that still can be kept perfectly.2. heat-shielding performance is best.ZrO2 thermal conductivity in all metallic oxides is minimum.3. corrosion resistance is best.The acid-alkali-corrosive-resisting ability of ZrO2 is better than Al2O3 and SiO2 greatly.4. not volatile, pollution-free under the high temperature.The high-temperature vapour of ZrO2 in all metallic oxides pressed to minimum, and chemical inertness, and high temperature is not volatile, pollution-free.
The alumina fibre plate is that a kind of main component is the docrystalline inorganic fiberboard of aluminium oxide, aluminium oxide oikocryst shape can be γ-, δ-, θ-, Alpha-alumina, it also contains the silica about 5% usually, in order to stablize crystalline phase, to suppress growing up of crystal grain under the high temperature.
Alumina fibre heat conductivity, heat shrink rate and thermal capacitance are all lower.Long-term serviceability temperature is 1300～1400 ° of C, is higher than common aluminum silicate fiber (1000～1100 ° of C).It has better chemical stability, can under sour environment, oxidizing atmosphere, reducing atmosphere and vacuum condition, use, and alkaline environment is also had certain corrosion resistance.The alumina fibre cost is very high, often presses different proportion to it and common aluminum silicate fiber for this reason and mixes, and processes plate, and goods such as felt are to adapt to the needs of different purposes and intensity.
The heat-shielding performance of ceramic fiber composite heat-insulating shield: at normal temperature (25 ℃) thermal conductivity is 0.015 W/mK, and the thermal conductivity in the time of 600 ℃ is 0.030 W/mK.The ceramic fiber composite heat-insulating shield is compared insulation effect with heat-insulating material commonly used at present can improve 2-10 times, can reduce heat insulation layer thickness 30%-50%.In the scene of a fire He under the high temperature, do not discharge any toxic substance.The heat resistance of high temperature resistant inorganic salt binder is stronger.
When the thickness of this heat-insulating composite plate was 130mm, hot-face temperature was elevated under 1200 ℃ of situation, and the temperature of huyashi-chuuka (cold chinese-style noodles) finally is stabilized in 70 ℃, if the ambient temperature of huyashi-chuuka (cold chinese-style noodles) is 24 ℃ at that time, so just a temperature rise is 46 ℃.
Zirconium oxide plate effect of heat insulation is good especially, and temperature is high more, and effect is good more, is used to press close to heat zone, can reduce temperature significantly; The alumina plate effect of heat insulation takes second place, and drops to temperature in the certain limit again, and last ceramic beaverboard composite adiabatic plate temperature drops in the claimed range.
Beneficial effect of the present invention: that this heat-insulating composite plate is not only in light weight, institute takes up space is little, shock resistance strong, good effect of heat insulation, and relatively economical is suitable for; But also be convenient to installation, compliance with environmental protection requirements.
