Description of the invention: [Technical field to which the invention belongs] The invention proposes a coating, in particular, a transparent high-insulation coating. [Prior Art], the usual way is to completely block the light without wavelength. 'Although it can effectively insulate, but the visible light needed in the normal environment - and the lack of natural light in the room is not necessarily energy saving. The method of heat-insulating 'traditional curtains' in the county of the object is also only to adjust the amount of light entering the chamber φ and not only to obtain the visible light required. Therefore, 'for this kind of environment, most of the market uses metal oxide rhodium or heat reflective film for glass insulation' so that only most of the visible light enters. 'These products are usually secret methods such as magnetron control. Vacuum steaming forging sol-gel method, these equipments are expensive to invest and are difficult to promote and apply in large areas. Therefore, in order to make this technology conform to the general building coating construction method and reduce the cost, the invention has been developed. A kind of transparent high-insulation coating, which is used to solve the problem of high cost of magnetron emission control method and equipment investment. SUMMARY OF THE INVENTION The present invention provides a transparent high-insulation coating comprising: particles selected from transparent metal oxides, which have a miscellaneous amount of between 1 (M(9) gamma such as nano-oxidation Indium bismuth (10)), nano cerium oxide (10)), GZ lanthanum, aluminum oxide (10)), Sn 〇, oxidized (ΖηΟ), ΙΖ0, titanium dioxide (10) 2), nano gold, nano silver or any combination thereof The weight percentage of the coating of the metal oxide is: lbg contains 1 〇g (ie 0·01 ～0.13⁄4); and the substrate of the coating is any one or combination of the following materials: A: temperature resistant and waterproof The resin may be: polyacetal, epoxy resin, polyester, pu, acrylic (press 5 201022382 resin), polyvinyl acetate, polyvinyl alcohol. B: Water. C. Auxiliary agent (0.1%~1%), which can be: leveling agent, antifoaming agent, Baocheng agent, dispersing agent dispersing agent, brightening agent, thickening agent and film forming auxiliary. D: the pore-expanding agent ' can be: polyethylene glycol (PEG)), propylbenzene emulsion. [Embodiment] For the purpose of achieving the transparent high heat-insulating coating of the above invention, a preferred embodiment is proposed here, and the efficacy is verified as follows. Firstly, in order to achieve transparency and heat insulation effect, the material selected in the present invention must have good visible light penetration capability and near-infrared reflection and isolation capability, and the energy band width Eg of the selected material must be greater than the visible light energy. Thus, under the illumination of visible light, the intrinsic excitation of the material is not caused, and since the particle size of the selected inorganic nanomaterial is much smaller than the wavelength of visible light, it has a certain diffraction effect on visible light, so that it is transparent to the entire visible light. . Moreover, since the infrared band is not absorptive to the wide band material, and because the nano particles have high scattering and high reflection ability, when the particle geometry is much smaller than the radiation wavelength, and the spacing between the scattering particles is larger than the radiation wavelength' The scattering coefficient of the coating obtained by Rayleigh scattering is as follows: 2 2 2 2 2 2 4 Τ(λ) = (4^ nsp s( η - η〇Μ( η + 2 /?0; ; Λλ where: ηΟ Represents the refractive index of the medium supporting the scattering source; 11 indicates the refractive index of the scattering particles; indicates the volume of the scattering particles; ns indicates the degree of the particles. For a given scattering power m, the particles of the material at the most effective scattering wavelength are 柽/k, Where k = 0.9 (m2 + 2) / n; r (m2 - l) m = η0 / η; where the refractive index of the tree deer in the paint; n0 is the refractive index of the filler; m is the scattering ability. 201022382 The above analysis shows that The type of reflective material inside the coating, the particle size distribution and the refractive index will have a certain effect on the thermal insulation effect of the material. As mentioned above, the ideal transparent insulating nano-coating should be visible to the visible part of sunlight. Has a good penetration side, and has a near-infrared portion Good barrier, reflective side, to achieve transparency and heat insulation effect 'Use materials with good visible light penetration and near-infrared reflection and barrier properties... For visible light demand, the choice should be E: g must be greater than visible light Energy material, and the particle size should be smaller than its wavelength'. For infrared light, choose high-reverse or high-surface ratio light or white © inorganic pigment as the pigment filler of transparent insulating nano-coating. The present invention has finally completed the present invention. The transparent high heat insulating coating of the present invention comprises: particles selected from transparent metal oxides, wherein the particle size is between 10 and 10 11111, such as nano indium oxide.钖(ΙΤ0), nano-oxidation error recording (AT0), GZ0 (Ga-doped ZnO), oxidized zinc (AZ0; A1-doped ZnO), SnO, zinc oxide (ΖηΟ), ΙΖ0, titanium dioxide (Ti02), Nai Any one or combination of rice gold and nano silver; wherein the weight percentage of the coating of the metal oxide is 1 to 10 g (ie 0.01 to 0.1%) in 1 kg; and the substrate of the coating is the following Any or combination: A: temperature resistance The water resin may be: polyacetal, epoxy resin, polyester, pu, acrylonitrile (acrylic resin), polyvinyl acetate, polyvinyl alcohol B: water C: auxiliary (0.1%~ 13⁄4), can be: leveling agent, defoamer, humectant, bismuth coupling agent, dispersant, brightener, thickener, filming aid. 7 201022382 - D : pore-expanding agent, can be: poly Ethylene glycol (PEG), styrene emulsion. The particles of the transparent metal oxide selected from the main materials of this experiment are AT〇, and the other equivalent metal oxides can be substituted for 'the size of the particles used is about 3 〇 nm, about 3 to 5 grams of transparent metal oxide per kilogram of paint (by pressing, if added 丨 ~ (7) grams also retains the effect of transparent insulation, but the experimental results are not described again) 'Figure 1 is the light wavelength penetration The schematic diagram shows that the above material has a transmittance of about 85% in the visible light portion and only about 40% in the infrared light transmittance portion, so that most of the visible light can be retained, for more details. Insulation verification, with a transparent test piece with a thickness of about 1 cm under Φ, the test standard As shown in Table 1, the light source uses i〇〇w iodine tungsten lamp (wavelength is similar to sunlight), the temperature detector is YS_947D thermocouple temperature detector, the detection distance is 10cm, and the detection time is 3, 5, 10 minutes respectively. The instrument for measuring the light transmittance is a full-band spectrometer (0-2000 nm), and the test results of Table 1 are shown in Figure 2 in a schematic manner. Table 1 Test Standard Item Specifications Light source 100W iodine tungsten lamp (wavelength approximation of sunlight) Thermometer YS-947D thermocouple temperature detector detection distance 10 cm Detection time 1,3,5,10 min Light transmittance full-band spectrometer ( 0-2000 nm) Please refer to Fig. 2, which is a temperature statistical comparison chart of the present invention, wherein: 8 201022382 Fig. 2A shows the comparison of the glass and the thermal insulation coating/glass according to different illumination times. Figure 2B shows the comparison of glass, heat-insulating paint/glass and air in different lighting times. It can be clearly seen from Fig. 2 that under the illumination of the light source and the heat-insulating paint/glass, the temperature difference is the highest under the irradiation for 3 minutes, and the light source is irradiated on the glass, the heat-insulating paint/glass and the heat-insulating paint/air. The temperature difference was the highest after 3 minutes of irradiation, and the temperature did not rise after 3 minutes of irradiation. Conclusion: Since most of the solar thermal energy is mainly from infrared rays with a wavelength of about 1 〇〇〇 nm, the results show that the coating can effectively block infrared rays by about 6〇%.
