Background
In recent years, the center of gravity of the glazing film market in China is shifted from automobile film sticking to building glazing films. As the transmittance of the common transparent glass to visible light and solar radiation energy is up to more than 80%, people feel dazzling, burning and uncomfortable in summer, and the energy consumption of the refrigeration equipment is increased; a large amount of heat can be dissipated in winter, and the heating efficiency is poor; in addition to selecting products with metal, metal compounds or other substances plated on glass and metal ions migrating to the surface layer of the glass, more and more people are interested in energy conservation by using architectural glazing films because of lower cost, high production efficiency and resistance to shattering and scattering of the architectural glazing films.
At present, the technology of the building glass window film in developed European and American countries is mature, the popularity rate is up to more than 80%, the indoor and outdoor glass window films for buildings are common, the indoor glass window film technology in China is mature, but the outdoor glass window film is not solved, the application of the outdoor glass window film is limited due to the problems of poor weather resistance, easy oxidation and fading of metal films, heat insulation and fading and the like, and the outdoor glass window film in China is still mainly imported.
Chinese patent CN201610920101 discloses a heat-insulating wear-resistant window film, which comprises a substrate layer and a heat-insulating wear-resistant layer, wherein the heat-insulating wear-resistant layer comprises acrylate monomer, modified polyurethane, ultraviolet absorbent, UV light-curing resin, nano metal oxide, photoinitiator, silicon carbide, defoamer and auxiliary agent, and the prepared window film has good wear resistance, weather resistance and heat insulation, and can be widely used in industries such as automobiles, buildings and the like. However, the above technical scheme has the problems of uneven dispersion of inorganic filler, easy oxidation of metal oxide, poor heat insulation effect and the like.
Chinese patent CN 201410705978 discloses a flexible film comprising: a flexible substrate; a first optical film compounded on the surface of the substrate; a second optical film laminated to a surface of the first optical film; a third optical film laminated on the surface of the second optical film; the first optical film is a NiCr film; the second optical film is a copper alloy film; the third optical film is a NiCr film; the ratio of the thickness of the third optical film to the thickness of the first optical film is in the range of 1.2-2. In the technical scheme, the first optical film and the third optical film are used as medium layers, and the visible light transmittance of the copper alloy layer can be modified; however, the technical scheme has 11.5% of visible light reflectivity, 75% of infrared light reflectivity, poor barrier property and poor weather resistance.

Further preferably, the average number of isocyanate groups of the aliphatic isocyanate curing agent is 2.3 to 3.
The applicant finds that the building external adhesive film prepared by adopting the aliphatic isocyanate curing agent with the average number of isocyanate groups of 2.3-3 and the aliphatic polyester polyol with the number average molecular weight of 500-2200 is not easy to generate yellowing in the experimental process, has excellent chemical stability and light and weather resistance, and is probably because: the aliphatic isocyanate curing agent does not contain a benzene ring structure with double bonds, does not have conjugated characteristics, has low reactivity under light, and is not easy to generate reaction discoloration. The applicant further discovers that the building external adhesive film produced by adopting the aliphatic isocyanate curing agent with the average number of isocyanate groups of 2.3-3 and the aliphatic polyester polyol with the number average molecular weight of 500-2200 also has certain self-repairing capability, because the combination property of the aliphatic isocyanate curing agent under the preferential isocyanate groups and the aliphatic polyester polyol is good, and the aliphatic isocyanate curing agent can quickly react to repair scratches after being damaged.

The applicant finds that the oxidation resistance of the building external-application energy-saving film can be improved and the ageing resistance of the building external-application energy-saving film can be improved by adopting the combination of the titanium dioxide nano particles and the zinc oxide nano particles in the experimental process. The possible reasons for the guess are: the titanium dioxide nano particles are rutile crystal titanium dioxide nano particles, have compact atomic structure arrangement and high density, and can have good reflection effect on sunlight. The applicant further found that the titanium dioxide nanoparticles have a certain adsorption effect on the zinc oxide nanoparticles, the zinc oxide nanoparticles absorb energy under light to generate electron transition, the fermi level of the titanium dioxide nanoparticles is lower than that of the zinc oxide nanoparticles, the electrons of the zinc oxide nanoparticles after light excitation flow to the titanium dioxide nanoparticles partially, the Schottky structure formed between the zinc oxide nanoparticles and the titanium dioxide nanoparticles enables the electrons to be separated from holes, the photoinduced electrons are captured and reduced by oxygen in the air to form oxygen free radicals, the zinc oxide remaining holes react with water in the air to form hydroxyl free radicals, the oxygen free radicals react with the hydroxyl free radicals to generate harmless water and carbon dioxide, the oxidation effect of the generated oxygen free radicals is reduced, and the oxidation effect of the energy-saving film externally attached to the building is reduced.

Preferably, the hot melt polymer is polyethylene terephthalate.
Preferably, the mass ratio of the metal oxide nano particles, the hot melt polymer and the solvent is 1 (2-5): (10-50).
