Description

Method for preparing patterned glass by toughening and coating
Technical Field
The invention belongs to the technical field of glass fine and deep processing, and particularly relates to a method for preparing patterned glass by toughening and coating.
Background
Coated glass is also known as reflective glass. The coated glass is prepared by coating one or more layers of metal, alloy or metal compound films on the surface of glass to change the optical properties of the glass and meet certain specific requirements. The coated glass adopts a magnetron sputtering process to carry out physical coating on a glass interface so as to reduce the heat transfer loss of the glass caused by radiation, effectively inhibit the transmission of infrared light, reduce the heat exchange at two sides of the glass so as to achieve good energy-saving performance, optical performance and environmental protection performance, thereby being popular with architectural designers and being widely applied to buildings around the world. However, with the increasing demand of the market today for aesthetic diversification of glass, it is required that the glass not only has energy saving performance, but also presents delicate patterns.
In the prior art, the method for preparing the Low-e coated glass with the pattern has the following three representatives:
1. high-temperature glaze silk-screen method: glaze with gloss is needed in the silk-screen printing process, so that the preparation cost is low; secondly, because the metal particles are added into the lustrous glaze, the gauze with the printing mesh number of 90-120 meshes is needed, and the pattern contour is not smooth and has burrs.
2. A sticker coating method: sticking a sticker with a hollow pattern, which is carved in advance, on the surface of the glass, and then coating a film; the method has the defects that the integrity of the paster is poor, and after the film coating is finished, the efficiency of tearing the paster is low and the film layer is easy to damage.
3. A patch coating method: covering the surface of the glass with a patch manufactured according to the shape of the pattern, and then coating the glass with a film; the process has the limitation that the patterns which can be processed by the process are concise and not complicated.
Disclosure of Invention
The invention aims to provide a method for preparing patterned glass by tempering and coating, aiming at the problems in the prior art, and the technical problem to be solved by the invention is how to optimize the production process of the patterned glass, so that the patterned glass is simpler and has high yield.
The purpose of the invention can be realized by the following technical scheme: a method for preparing pattern glass by toughening and then coating is characterized by comprising the following steps:
A. slicing: selecting a glass original sheet, and cutting the glass original sheet according to production requirements;
B. grinding and washing: edging the glass sheet and cleaning the glass sheet;
C. tempering: sending the glass which is subjected to edge grinding and cleaning into a tempering furnace for tempering the glass;
D. manufacturing a screen plate: manufacturing a screen plate by using 150-250 meshes of gauze, wherein the screen stretching pressure is between 15 and 20N, then coating photosensitive adhesive on the gauze, after the photosensitive adhesive is dried, laying a film with a pre-designed hollow pattern on the gauze to ensure that the film is tightly contacted with the gauze and the four sides are closed, vacuumizing to ensure that the contact surface of the film and the gauze is pasted without a cavity as much as possible, and finally exposing and developing the film to ensure that the film pattern is supported on the gauze;
E. preparing a coating: the paint consists of epoxy resin 50-55 wt%, ethylene glycol monobutyl ether 12-14 wt%, polyether siloxane compound 4-6 wt% and pigment and stuffing 18-25 wt%; fully mixing the components, and diluting to ensure that the components can meet the requirements of silk screen printing;
F. and (3) silk-screen printing: mounting the manufactured screen plate on a screen printing machine, polishing a scraper and an oil knife by using fine sand paper of 800-1000 meshes, mounting the screen plate on a clamp of the screen printing machine, setting parameters such as pressure, tool stopping position and screen distance of the screen printing machine, and pouring a proper amount of prepared coating into the screen plate to perform screen printing operation;
G. and (3) drying: putting the glass after the silk-screen printing of the pattern into drying equipment, drying and curing the silk-screen pattern, controlling the temperature of the drying operation at 200-230 ℃ and the operation time at 10-12 minutes;
H. secondary cleaning: feeding the glass with the paint dried into a cleaning machine to complete secondary cleaning, so that the surface of the glass is clean and dustless;
I. magnetron sputtering coating: according to the structure of the film layers on the glass and the thickness of each film layer, setting technological parameters of target materials, the number of the target materials, air pressure, protective gas components and the like at each section of a magnetron sputtering coating production line, and then conveying the glass to a coating cavity of the magnetron sputtering coating production line to finish magnetron sputtering coating operation;
J. removing the coating layer: putting the coated glass into a cleaning tank filled with an organic solvent, soaking for 2-3 minutes, and putting the glass into a cleaning machine to clean the glass for three times by adopting clear water; the organic solvent comprises 15-25% of acrylic polymer and 75-85% of mixed alcohol ether solvent, and can soften and peel off the coating layer on the surface of the glass without damaging the Low-E film layer, so that the hollow Low-E film pattern is presented on the surface of the glass.
The method adopts the coating which can be solidified at Low temperature and is insoluble in water to carry out pattern silk-screen printing, so that the pattern can be washed by water without falling off after the silk-screen printing is finished, and the coating layer is removed by soaking the coating layer in a special organic solvent after the magnetron sputtering coating is finished, thereby obtaining the Low-E film with the hollow pattern.
The invention has the advantages that:
1. the method is simple and effective, and the Low-E film layer on the surface of the glass can not be damaged, so that the production efficiency of the pattern coated glass is greatly improved, and the yield is greatly improved.
