Technical scheme of the present invention is as follows, and the temperature controllable nano transparent heat-insulating is coated with film component and comprises by weight percentage: matrix resin [thermoplastic acrylic resin, Hydroxylated acrylic resin, the thermosetting acrylic resin, fluorocarbon resin] 40～80%, Doped Nanosize tungsten vanadium oxide 2～15%, dispersion agent [polyurethanes, polysiloxane, the poly carboxylic acid ammonium salt, polymeric carboxylic] 0.2～5.0%, defoamer [polysiloxane, non-silicone high molecular polymer, modified polyorganosiloxane] 0.1～0.5%, flow agent [polysiloxane, modified polyorganosiloxane, acrylate copolymer, the fluorin modified crylic acid ester copolymer, TSP] 0.1～1.0%, thinner [dimethylbenzene, toluene, N-BUTYL ACETATE, propylene-glycol ether acetate, pimelinketone, butanols] 5～30%, solidifying agent [HDI affixture, the HDI tripolymer] 0～40%, linking agent [propyl carbinol etherified amino resins, the isopropylcarbinol etherified amino resins, methanol etherification aminoresin] 0～40%, adhesion promoter [amino containing silane, epoxy radicals silicone hydride, oil-free polyester resin] 0.5～3%.
Doped Nanosize tungsten vanadium oxide in above-described embodiment is for using pyrolysis method, hydrothermal synthesis method, vacuum reducing method etc. to produce, and its transformation temperature scope is mixed a kind of in the tungsten vanadium oxide powder between 20 ℃～35 ℃, can select according to the environment for use temperature requirement.When film temperature is lower than this temperature, film and be isolator, for having no effect, but when film temperature reaches this design temperature, the hot metal phase (M) of mixing the tungsten vanadium oxide and cryogenic semiconductor phase (S) are understood when this temperature and are undergone mutation to the biography of light and heat amount.Be accompanied by the variation of structure, mixing some physicals of tungsten vanadium oxide also can undergo mutation, the hop of 4-5 the order of magnitude occurs such as resistance (rate), also have simultaneously the sudden change of susceptibility, light refractive index, transmissivity and reflectivity, especially change the most obvious at infrared and near-infrared band optical transmittance.When low frequency, unbound electron is repeatedly accelerated collision by the electric field of certain direction in each semi-period of alternation light, this polarized free electron gas is very strong to the electromagnetic shielding action of light field, and namely the free electron gas type material has very strong reflectivity R at the low frequency infrared region.When optical frequency increases to certain frequency, this moment, the inertia of electronics can not be followed the light field that high frequency changes, and the absorption of this plasma body electron pair light field and reflection are all very weak, and this threshold frequency that makes material enter the clear area is called as plasma frequency.When optical frequency further increases, this moment, the energy of photon was enough to make the fixed electron of material to produce the intrinsic band to become unbound electron to the excited state transition, and visible light belt just meets with the λ g-λ p that films.Semi-conductors etc. so Doped Nanosize tungsten vanadium oxide has high shielding rate in the infrared light district, have high transmitance at visible region from becoming short because of the increase of carrier concentration with respect to the intrinsic plasma wavelength, at ultraviolet region high specific absorption are arranged.The character that it is worth noting the most these sudden changes before and after transformation temperature is reversible.
The test of heat reflection effect is illustrated in figure 1 as the solar radiation spectrogram.
After solar radiation entered atmospheric layer, the X ray in the solar spectrum and the shorter radiation of other wavelength can not arrive the earth's surface because being absorbed consumingly by nitrogen, oxygen and other atmospheric molecule in Kennelly heaviside layer; Most of ultraviolet ray is absorbed by ozone.As for weakening of the spectral energy in visible-range, then mainly be because the strong scattering of earth atmosphere is caused; And weakening of the spectral energy in the near infrared range then mainly is the result that steam absorbs the solar radiation selectivity.Wavelength surpasses the far-infrared radiation of 2.5um, and it is just quite low in the yield of radiation in the atmospheric layer upper bound, adds CO2 and H2O absorbs consumingly to it, has been very little so arrive ground energy.In fine situation, be 1 o'clock in air quality, the solar radiation spectral distribution that earth surface can receive adopts subsection integral, draws the total energy ∫ of solar radiation
0 ∞α ε E
iD λ.In the formula, α is specific absorption, and ε is emittance, and E λ is monochromatic ray solar radiation density.As shown in Figure 1, solar radiation spectrogram.Therefore, in the solar radiation that arrives ground, in the wavelength region that concentrates on 0.2～3um more than 97% of quantity of radiant energy, wherein:
The ultraviolet region: ﹤ 0.38um accounts for 7%;
Visible region: 0.38～0.78um accounts for 47%;
Near infrared light area: 0.78～2.5um accounts for 42%;
Farinfrared: ﹥ 2.5um accounts for 4%.
Adopt a kind of absolute test method of spectral reflectivity.Use the UV, visible light near infrared spectrometer (wavelength region: 165～3300nm) testing tools, sample placed 24 hours in thermostatic chamber after, test the spectral reflectivity under this temperature.Sample is positioned over the integrating sphere central position, by test sample spectral reflectivity when the wavelength X i, calculates the solar reflectivity of sample by (1) and (2).
