Technical Field

Background
With the continuous application of off-line coating in the current buildings, the coated products are diversified, and the development of the film system is different. The design style of architects is more and more innovative. The color of the off-line coating film is changed day by day while the high performance of the product is met. In order to meet the requirement of designers, it is difficult to realize coating patterns (such as dot coating, line coating, and other pattern coating) in the prior art. In the prior art, a silk screen printing technology is adopted, and an ink pattern is formed on the surface of glass, but the silk screen printing technology and the magnetron sputtering coating technology are directly adopted, so that a coating pattern cannot be realized. As is well known, the vacuum magnetron sputtering technique is to uniformly deposit a material on a target material on the surface of glass by bombarding the target material with ions in a high vacuum chamber, thereby forming a film layer with a uniform nano-scale thickness on the surface of the glass. The screen printing has few grids, ink is squeezed into the grids through external force and then falls on the surface of the glass to form patterns, materials on the target cannot be deposited on the surface of the glass through the grids to form coating patterns, and the target is very close to the surface of the glass during vacuum sputtering, so that objects such as molds cannot be covered on the surface of the glass, and the film forming effect of the vacuum sputtering is influenced.

The coating film pattern is a dot pattern, a polygonal pattern, a long pattern or a character calligraphy and painting pattern.
The method of the invention adopts a zigzag mode instead of directly adopting screen printing patterns for magnetron sputtering coating, and the idea of the invention is as follows: adopting washable ink to perform screen printing to form a mould pattern, wherein the mould pattern is complementary with a coating pattern, drying and cleaning the formed mould pattern, detecting the mould pattern again, and entering a coating chamber when the mould pattern meets the cleanliness requirement of vacuum magnetron sputtering; magnetron-controlled sputtering coating (magnetron sputtering) is a coating technology that a coating material is used as a target cathode, argon ions are used for bombarding a target material to generate cathode sputtering, target material atoms are sputtered onto a workpiece to form a deposition layer, and the coating material is kept in a solid state all the time and does not form a molten pool. Therefore, after passing through the coating chamber, the whole glass surface is coated, and the ink patterns (mould patterns) are cleaned by using a cleaning agent to leave coating patterns. The invention adopts the ink which is resistant to water washing, the pattern of the mould is not removed when the glass is washed, and after the film coating, the pattern of the mould (the surface of which is also provided with the coating film) is removed by adopting the cleaning agent which can dissolve the ink, and the pattern of the coating film can not be cleaned only, thus obtaining the glass with the coated pattern.
The ink of the invention is preferably alcohol-soluble ink which is washable, and the corresponding cleaning agent is ethanol or neutral solvent containing ethanol. Firstly, the ink coating is well compatible with a silk screen, photosensitive resist and glass and meets the requirements of a silk screen printing process; secondly, because of the vacuum magnetron sputtering technology, the glass cleanliness is required to be very high, and the key factor influencing the coating quality is the cleaning quality of the glass surface, so that the cleaning machine used in the coating process can be provided with a disc brush and rolling brush combination mode, the cleaning length is incomparable with a common cleaning machine, so that the coating is required to have good adhesive force with the glass surface at normal temperature, and once the adhesive force is insufficient, the pattern can be damaged, and the coating pattern can be directly influenced; the inks used for screen printing must therefore be water-fast; the coating process considered then was carried out under high vacuum (sputtering zone up to 1.0X10-6Mpa) under the environment with a certain temperature, relates to the superposition and covering of various sputtering film layers, and the physical property and the chemical property of the coating must be stable, otherwise, the adhesion and the optical parameters of the film layers are directly influenced; finally, the product coated with the film is not a final product, so that the printing coating is required to be perfectly removed on the basis of meeting the requirement of the last complaint, the cleaning agent is very important as a cleaning agent for removing the printing coating, the cleaning agent is required to completely remove the printing coating under the condition of ensuring the complete coating (the coating has strict requirement on the pH value of the cleaning agent), and the cleaning agent is required to be matched with the printing ink coating and the coating.
The invention adopts the ink which is washable to form a mould pattern on the surface of the glass, then coats a film, and then adopts the cleaning agent which can dissolve the ink to remove the mould pattern (the surface of the mould pattern is also coated with a film), but only the coated pattern can not be cleaned, thus obtaining the coated pattern glass. The invention does not need to additionally increase large-scale equipment, and has simple method and strong operability.
