[0001] The invention relates to the technical field of glass, and in particular to a production method of light-transmitting and strong colored glaze glass and the light-transmitting and strong colored glaze glass. Background Art

[0002] Colored glazed glass is a kind of glass deep-processing product that is coated with glaze on the glass surface and then heated at high temperature in a tempering furnace so that the glaze is permanently sintered on the glass surface. This product not only has rich colors and patterns, but also has good stability and durability after tempering because the glaze used is an inorganic material. It also has safety performance. It has now become an increasingly widely used decorative and safety building material in various types of buildings.

[0003] At present, the main method for preparing light-transmitting colored glaze glass is to make certain areas of the glass not printed with glaze material, so as to achieve light transmission of the colored glaze glass. For the production of light-transmitting colored glaze glass, the screen printing method is generally used. However, when the screen printing method is used to produce light-transmitting colored glaze glass, the problem of insufficient adhesion between the glaze layer and the glass is easily generated, and the problem of too many light leakage points is also generated. Summary of the invention

[0004] The purpose of the present invention is to provide a method for producing light-transmitting and strong colored glaze glass and light-transmitting and strong colored glaze glass. By sequentially subjecting the surface of a glass substrate to argon plasma treatment and oxygen plasma treatment, the glaze layer is firmly bonded to the surface of the glass substrate after being dried and tempered, and has strong adhesion, and can also reduce the generation of light leakage points and streaks. At the same time, the present invention can enable the obtained colored glaze glass to maintain a high light transmission performance.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for producing light-transmitting and durable colored glaze glass comprises the following steps: S1: Slicing, edge grinding and cleaning the float glass to obtain a glass substrate; S2: treating one side surface of the glass substrate with argon plasma first and then with oxygen plasma to obtain a single-sided plasma-modified glass substrate; S3: printing the glaze on the modified surface of the single-sided plasma-modified glass substrate by screen printing, wherein the area of ​​the glass substrate not printed with the glaze accounts for more than 1 / 5 of the single-sided area of ​​the glass substrate; and then performing a drying process; S4: tempering the glass obtained in step S3.

[0006] Preferably, when the argon plasma treatment is performed, the treatment power is 500-700 W and the treatment time is 10-15 min.

[0007] Preferably, during the oxygen plasma treatment, when the treatment power is 400-500 W, the treatment time is 15-20 min.

[0008] Preferably, in step S3, the mesh size of the screen printing screen is 200-300 meshes; The viscosity of the glaze is 80-150 dpa·s; The temperature of the drying process is 150-160°C.

[0009] Preferably, in step S4, according to the thickness of the glass substrate in step S1, the tempering treatment is performed at a heating time of 50-60 s / mm, and the temperature of the tempering treatment is 600-630°C.

[0010] Preferably, the step S3 comprises the following steps: coating one side of the glass substrate printing glaze obtained after drying with a layer of silica sol, and then performing drying.

[0011] Preferably, the coating amount of the silica sol is 0.05-0.08 kg / m 2 .

[0012] Preferably, the method for preparing the silica sol comprises the following steps: Add ethyl orthosilicate and methyltriethoxysilane to anhydrous ethanol, stir and mix, then add water and stir for 20-30 minutes, then add ammonia water, continue stirring for 1-1.5 hours after the addition is complete, and then age under sealed conditions at an aging temperature of 25-30° C. for 7-8 days; The volume ratio of the tetraethyl orthosilicate, methyltriethoxysilane, anhydrous ethanol, ammonia water and water is 5.5-7:1.5-2:35-40:0.7-0.9:1, and the concentration of the ammonia water is 25-28wt%.

[0013] Preferably, the drying temperature is 150-160°C.

[0014] As a general inventive concept, the present invention also provides a light-transmitting and durable colored glaze glass, which is prepared by the above production method.

[0015] The beneficial effects of the present invention are: 1. The present invention can significantly enhance the roughness of the surface of the glass substrate in microstructure by sequentially subjecting the surface of the glass substrate to argon plasma treatment and oxygen plasma treatment, and can effectively enhance the bonding force between the surface of the glass substrate and the glaze layer, while the roughness will not affect the flatness and smoothness of the glaze layer. The oxygen plasma treatment can also enrich the active groups on the surface of the glass substrate, and the active groups interact with the glaze to further enhance the bonding force between the glaze and the surface of the glass substrate. The present invention can enhance the bonding force between the surface of the glass substrate and the glaze layer at the physical and chemical levels by sequentially subjecting the surface of the glass substrate to argon plasma treatment and oxygen plasma treatment, so that the glaze layer is firmly bonded to the surface of the glass substrate after drying and tempering treatment, has strong adhesion, and can also reduce the generation of light leakage points and streaks.

[0016] 2. The present invention further coats a layer of silica sol on the surface of the glass substrate with the printed glaze, and in combination with its own drying process and the tempering process of the colored glaze glass, a thin layer of silica can be formed on one side of the colored glaze glass having the glaze layer, which can protect the glaze layer and enhance the bonding strength between the glaze layer and the glass substrate. Due to the protection of the thin layer of silica, the glaze layer is not easy to change color and will not fade after long-term use. However, the addition of this process will increase the light leakage points to a certain extent.

[0017] 3. The production method of the present invention can be used to prepare colored glaze glass with high glaze layer firmness, and by controlling the printing area of ​​the glaze on the glass substrate, the obtained colored glaze glass can maintain high light transmittance.

[0052] S2: The glaze is printed on one side of the glass substrate by screen printing, the mesh number of the screen printing is 250 mesh, and the viscosity of the glaze is 150 dPa·s; the area on the glass substrate where the glaze is not printed accounts for 3 / 8 of the single side area of ​​the glass substrate; and then the glass substrate is dried at 150°C.

[0054] According to the method in "JCT1006-2006-Glazed Tempered and Glazed Semi-tempered Glass", the light leakage points, streaks, pattern integrity and glass adhesion performance of the products in Examples 1, 3, 6 and Comparative Example 1 were tested. The specific method for testing glass adhesion performance is as follows: prepare 3 products as samples, and use a single-sided blade to repeatedly scrape the glass glaze layer in an area of ​​25mm×75mm 20 times, with the blade and the sample at a 45° angle. Draw a line with water along the 75mm direction, and 15 minutes after the line is drawn, apply fine grinding paste on the line and wipe it; under the irradiation of a scattered light source, use the naked eye to randomly observe the glaze layer to see if there is any ink residue; if there is any ink residue, it means that the pores on the glaze will allow water to penetrate, which may cause the glaze layer to fade or cause the glaze layer to separate from the glass substrate in an icy climate. The product glaze appearance quality and glass adhesion performance are shown in Table 1.

[0055] Table 1 Product glaze appearance quality and attached glass performance

[0056] Note: S is m 2 As a unit of glass substrate.

[0057] It can be seen from Table 1 that the colored glaze glass prepared in the embodiment of the present invention has only light leakage points with a diameter of ≤0.5 mm, which are not concentrated, and no spots can be observed at a backlight of 600 cm, the pattern integrity is high, and it has excellent glass adhesion performance. As can be seen from the comparison between Example 6 and Example 3, coating the surface of the glass substrate of the printed glaze with a layer of silica sol will increase the light leakage points to a certain extent, but it will not affect the colored glaze glass from reaching the application standard.

[0058] From the comparison between Comparative Example 1 and Example 3, it can be seen that if the glass substrate is not subjected to argon plasma treatment and three-dimensional modification such as oxygen, the light leakage points will increase significantly, spots will be generated, and the glass adhesion performance will also be significantly reduced.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
