Description

Method for preparing patterned glass by coating and tempering sequentially
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 coating and tempering.
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 performance 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 heat transfer loss of the glass caused by radiation, effectively inhibit infrared light transmission, and reduce heat exchange at two sides of the glass so as to achieve good energy-saving performance, optical performance and environmental protection performance, so that the coated glass is popular with architectural designers and 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 patterns is represented by the following three methods:
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. The paster coating method comprises the following steps: 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 sticker is poor, and after the film coating is finished, the efficiency of tearing the sticker is low and the film layer is easy to damage.
3. A patch coating method: covering the surface of the glass by adopting a patch manufactured according to the shape of the pattern, and then coating the film on the glass; 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 coating and tempering 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: the method for preparing the pattern glass by coating and toughening 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. manufacturing a screen plate: manufacturing a screen plate by using 150-250 meshes of gauze, wherein the screen stretching pressure is between 15-20N, then coating photosensitive glue on the gauze, after the photosensitive glue is dried, laying a film with a hollow pattern in advance on the gauze, enabling the film to be in close contact with the gauze, sealing the four sides of the film, vacuumizing to enable the contact surface of the film and the gauze to be attached without a cavity as much as possible, and finally exposing and developing the film to enable the film pattern to be supported on the gauze;
D. preparing the coating: the paint consists of epoxy resin mixture 50-55 wt%, ethylene glycol monobutyl ether 12-14 wt%, fatty amine curing agent 4-6 wt% and pigment and stuffing 19-22 wt%; fully mixing the components, and diluting to ensure that the components can meet the requirements of silk screen printing;
E. 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;
F. 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;
G. 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;
H. 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 into a coating cavity of the magnetron sputtering coating production line to finish magnetron sputtering coating operation;
I. tempering: sending the glass subjected to edging and cleaning into a tempering furnace for glass tempering operation; in the toughening process, the coating layer can be sintered and fluffy due to the high-temperature effect.
J. And (3) washing for three times: sending the toughened and cooled coated glass into a cleaning machine, and cleaning the toughened and cooled coated glass with clear water for three times; at the moment, the paint layer with fluffy surface can be easily cleaned, and further, the hollow-out Low-E film pattern is presented on the glass surface.
The method adopts the coating which can be solidified at Low temperature, is insoluble in water and can be sintered and loosened at high temperature to carry out pattern silk-screen printing, so that the pattern can be washed by water after the silk-screen printing is finished, and does not fall off, after the magnetron sputtering coating is finished, the pattern is automatically loosened in the toughening process, and then the coating layer is washed and removed, and the Low-E film with the hollowed pattern is obtained.
The invention has the advantages that:
1. the low-e film pattern glass processed by the process solves the problems that the colored glaze glass pattern does not have reflected light and glossiness, metallic color on glaze color, instability of bright color, sensitivity of color allocation and the like.
2. By using the production process, the building glass not only has pattern and color diversity, but also has energy-saving property.
3. The process has the advantages of simple production process flow, high efficiency and good product stability, and is suitable for continuous large-scale production.
