Below technical scheme of the present invention is made further explanation.
Temperature sensitive coating of the present invention is primarily of substrate material, luminescent material, thermally conductive material and solvent composition, required substrate material is the high molecular polymer that oxygen transmission rate is low, preferred polyoxyethylene glycol or polystyrene resin, because the light intensity of phosphorescence and fluorescence is very easily by the quencher of oxygen institute, if the oxygen permeability of substrate material is high, particularly when wind1 tunnel trial, temperature and oxygen quench luminescence intensity simultaneously, acquired results is the change that temperature and oxygen cause simultaneously, and the not only change that causes of representation temperature, so the polyoxyethylene glycol selecting oxygen transmission rate low or polystyrene resin.Substrate material of the present invention 100 parts, luminescent material 0.01 ~ 10 part, preferably 0.05 ~ 5 part, more preferably 0.1-1.0 part, thermally conductive material 1 ~ 80 part, preferably 20 ~ 60 parts, more preferably 25-50 part, solvent 20 ~ 300 parts, preferably 50 ~ 250 parts, more preferably 100-200 part.

Because temperature sensitive film is polymer coating film, its poor thermal conductivity, due to the thermograde existed between film layer, will introduce comparatively big error to experimental result, and spray such thin coating film and can bring difficulty to manufacture craft.Secondly, due to the poor thermal conductivity of polymer coating film, in wind1 tunnel trial, hot-fluid causes the change of the less temperature of film coated surface will be difficult to display.Therefore, we add micron order thermally conductive material in temperature sensitive film, its objective is that the thermal conductivity improving temperature sensitive film is with the thermograde reduced between film layer with improve temperature sensitivity, reduces the manufacture craft difficulty of sprayed coating film, and is conducive to raising measuring accuracy.
Thermally conductive material of the present invention comprises micron order aluminium powder, micron order lead powder and micron order silver powder, preferred micron order aluminium powder.Metal powder selected by the present invention is the metal powder with certain color, and wherein, the metal powder presenting black under normal temperature is inadvisable, and why material presents black, is because it can absorb the light of all wavelengths in visible light wave range.If use the metal powder of black as thermally conductive material, in the process of carrying out exciting with exciting light, the light splitting of metal powder meeting absorbent portion itself, affects the fluorescence intensity of luminescent material itself, thus brings certain error.So the metal powder that color presents light color is good selection, in addition, particle diameter is adopted to be the thickness that micron-sized metal powder is conducive to controlling film, so select the metal presenting light color at micron order in the present invention, preferred light gray metal powder.In addition, adding the topmost reason of thermally conductive material is improve the thermal conductivity of temperature sensitive coating, so the thermally conductive material added must be the metallic substance that thermal conductivity is good.The silver powder thermal conductivity adopted in the present invention is best, and aluminium powder takes second place, but because of silver powder cost higher, so metallic aluminium powder preferably selects.
The particle size range of micron order thermally conductive material of the present invention at 1-100 μm, preferred 20-80 μm, more preferably 20-40 μm.In temperature sensitive coating, add micron order thermally conductive material, the thermal conductivity that improve temperature sensitive coating film is with the thermograde reduced between film layer and improve temperature sensitivity, reduces the manufacture craft difficulty of sprayed coating film, is conducive to improving measuring accuracy.
Luminescent material of the present invention is the temperature-sensitive material that glows, preferred Y 2o 3: Eu 3+, Ba 2znS 3: Mn 2+, CaS:Eu 2+with trifluoroacetylation thenoyl europium (EuTTA), more preferably trifluoroacetylation thenoyl europium, its emission peak is 610 ~ 620nm.To temperature sensitive in 0 ~ 80 DEG C of temperature range, vary with temperature luminescent material fluorescence intensity meeting quencher, the decay according to fluorescence intensity can reflect temperature accurately.In certain temperature range, the relation between fluorescence intensity I and absolute temperature T can describe with Arrhenius equation:
ln I ( T ) I ( T ref ) = E nr R ( 1 T - 1 T ref )
E in formula nrnonradiative process activation energy,
R is universal gas constant,
T refbe reference temperature(TR), represent with absolute temperature K.
Temperature sensitive coating twists distribution to measure temperature with heat turn for various aerodynamics test.In hypersonic wind tunnel test, temperature sensitive coating not only observes transitions for flow image intuitively, but also can twist data according to metastable state and thermal transient transition model quantitative Analysis heat turn.Temperature sensitive coating is a kind of effectively technology to directly observation frictional belt is converted to turbulent flow from advection, there is obvious difference because stream field between advection and turbulent region turns to twist, temperature sensitive coating can twist by turning the change that surface temperature directly observed by line.Add the auxiliary of other technology, temperature sensitive coating turns the relation of twisting between flow field structure for studying heat in injection experiment is excited in sound insulation.Temperature sensitive paint image quantitatively can have been described to excite the shock of control (enhancer or inhibitor) heat to turn by sound and twist field.Be investigated with temperature sensitive coating and turned twisted field etc. by the interact heat in the complex separations flow field caused of Shock/Boundary-Layer.After suitably correcting temperature sensitive coating, by detecting emitted luminescence intensity, just remote-controlled mensuration pressure and temperature.
Temperature sensitive film of the present invention is polymer coating film, its poor thermal conductivity, due to the thermograde existed between film layer, will introduce comparatively big error to experimental result, and the thinner film of spraying can bring difficulty to manufacture craft.Secondly, due to the poor thermal conductivity of polymer coating film, in wind1 tunnel trial, hot-fluid causes the change of film coated surface less temperature will be difficult to display, so the film thickness of control temperature sensitivity film seems and is even more important in making processes.Temperature sensitive coating thickness of the present invention is at 1-100 μm.
The application of temperature sensitive film of the present invention, for the measurement within the scope of 0-100 DEG C, preferred 0-80 DEG C, more preferably the measurement within the scope of 20-80 DEG C, it is a kind of non-contact optical measuring method, for rating model surface temperature distribution, be preferred for rating model surface temperature distribution in wind1 tunnel trial, be widely used in aerospace, hot-short and the field such as environment and biological medicine.
Usefulness of the present invention is:
(1) invention adopts luminescent material to be trifluoroacetylation thenoyl europium; to temperature sensitive in 0 ~ 80 DEG C of temperature range; vary with temperature luminescent material fluorescence intensity and temperature linear, temperature can be reflected accurately, the measurement of 0 ~ 80 DEG C of temperature range can be used for.
(2) the present invention adopts and adds thermally conductive material for being ash gray micro-sized metal powder, improves the thermal conductivity of temperature sensitive coating film, reduces the thermograde between film layer, improve the response frequency of temperature, the sensitivity simultaneously also improved.
