Description
Technical Field
The invention relates to the technical field of glass surface coatings, in particular to antifogging glass and a manufacturing method thereof.
Background
In daily life, the condition that condensed mist on bathroom mirror surfaces, automobile glass or glasses is not clear is often encountered, the condition is caused because the ambient temperature is too high, water is evaporated, the mirror surface glass is cold, water vapor is condensed on the mirror surfaces to form tiny dewdrops, the lens action of the tiny dewdrops changes the original light path, and light passing through the glass becomes scattered and cannot be effectively imaged. The atomized glass can seriously affect the mirror surface or the transparent function of the glass, great inconvenience is caused to the life of people, and at present, glass with an antifogging function is developed by a plurality of manufacturers. The existing anti-fog technology has two major directions, namely, electric heating anti-fog; secondly, coating antifogging. The electric heating antifogging glass has the advantages that the temperature of the surface of the glass is increased through an electric heating mode, so that fog condensed on the surface of the glass is quickly evaporated, water vapor cannot form fog on the surface of the glass, the electric heating antifogging effect is prominent, the electric heating antifogging glass needs to be powered on when being installed, and certain potential safety hazards can be brought. The existing coating antifogging glass mainly plates a hydrophilic coating on glass, so that water vapor cannot form water drops on the surface of the glass, but forms a layer of uniform water film to achieve an effective antifogging effect.

Drawings
FIG. 1 is a schematic structural view of the present invention;
wherein, the coating comprises 1-nanometer zirconia layer, 2-nanometer tin antimony oxide layer, 3-nanometer silica layer, 4-nanometer molybdenum layer and 5-glass substrate.
Detailed Description
As shown in fig. 1 (which shows the relationship between the coatings on the microscopic scale, and is exaggerated), the preferred embodiment of the present invention is to use the vacuum magnetron sputtering method to plate 4 coatings on the glass substrate 5, from inside to outside: firstly plating a nano molybdenum layer 4; plating a nano silicon oxide layer 3; then plating a nano tin antimony oxide layer 2; finally plating a nano zirconia layer 1.
Wherein the third layer of the nano tin antimony oxide layer 2 is a functional layer for realizing antifogging. Nanometer tin antimony oxide, namely nanometer antimony-doped tin dioxide and antimony tin oxide, belongs to common materials in the field of nanometer materials, is relatively low in price and easy to purchase, and is mostly applied to the fields of static resistance and heat insulation at present. In the magnetron sputtering coating process, antimony can replace tin atoms in tin oxide in an ionization environment, so that the tin oxide is in an oxygen-deficient state, and nano-scale micropores are formed when the nano-tin antimony oxide is deposited on a substrate. The nano-micropores are substantially uniformly distributed in the two-dimensional direction of the glass matrix 5, so that a porous structure is formed on the surface of the glass matrix 5, and the porous structure is favorable for improving the hydrophilic property of the material: when water vapor is condensed on the surface of the material, micro liquid drops are firstly and evenly distributed on the surface of the material, but larger liquid drops which are continuously condensed are firstly filled in the nano micropores and are kept in the nano micropores due to the surface tension of the liquid, the liquid drops in the adjacent nano micropores are connected to form a water film along with the continuous condensation process, and the contact angle of water drops is macroscopically reduced by the infiltration state of the material, so that the surface of the glass forms a hydrophilic surface, and finally the antifogging effect is achieved.
It should be noted that, in order to achieve the antifogging effect, only the nano tin antimony oxide layer 2 is plated on the glass substrate 5, but the nano tin antimony oxide layer 2 is relatively non-wear-resistant and has a short service life, so that the nano zirconium oxide layer 1 can be plated outside the nano tin antimony oxide layer 2, the zirconium oxide has excellent wear-resistant and corrosion-resistant characteristics, the service life of the product can be effectively prolonged, the thickness of the nano zirconium oxide layer 1 is only 5-10 nm, the nano tin antimony oxide layer 2 is only substantially uniformly covered on the porous structure, and the hydrophilic performance formed by the porous structure is not influenced on the whole.
In addition, the nanometer tin antimony oxide layer 2 as the functional film needs to be plated at about 200 ℃ to achieve the best effect, and the nanometer molybdenum layer 4 with conductivity is plated on the glass substrate 5 firstly, so that the surface of the substrate can be conveniently heated in an ionization environment, and the surface of the glass substrate 5 can quickly reach and maintain the ideal temperature.
In addition, a nano silicon oxide layer 3 can be plated between the nano tin antimony oxide layer 2 and the nano molybdenum layer 4, and the function of the nano silicon oxide layer is to enhance the ductility of the film layer, so that the nano tin antimony oxide layer 2 serving as a functional film layer can be better combined with a glass substrate 5, and large-area and continuous production is facilitated.
It should be noted that the use of vacuum magnetron sputtering to plate the coating (also called plating) in the preferred embodiment is only a preferred embodiment, and other coating processes such as arc ion plating which generate ionization and belong to the physical vapor deposition method can be used, and the vacuum magnetron sputtering has the following advantages: 1. the application of the method in the field of film coating is wider, and related supporting industries are complete, so the method is easy to implement, the coating cost is relatively low, and large-area and continuous production is facilitated; 2. compared with other coating technologies, the magnetron sputtering coating has the characteristics of good film compactness and good quality, and can obtain an ideal nano coating, particularly has no large particle pollution problem, and has better film consistency, so that the performance of the functional film (namely the nano tin antimony oxide layer 2) can be ensured to be continuous and stable.
Finally, it should be pointed out that the glass substrate 5 of the present invention can be either transparent glass or a mirror; it can be inorganic glass, organic glass or even bright metal; in any case, any optical device having transparent or reflective properties of the material itself can be used as the glass substrate 5 of the present invention to perform the antifogging treatment.
