Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass, in particular to a production method of light-transmitting and firm colored glaze glass and the light-transmitting and firm colored glaze glass. BACKGROUND

[0002] The colored glaze glass is a kind of deep processing product of glass, which is obtained by coating glaze on the surface of glass and then sintering the glaze on the surface of glass by high-temperature heating in a steel furnace. The product has rich colors and patterns, and has good stability and durability after steeling due to the use of inorganic materials as glaze. In addition, the product has safety performance, and has been widely used in various buildings as a kind of decoration and safety building material.

[0003] At present, the main method for preparing light-transmitting colored glaze glass is to not print glaze on some areas of the glass, so as to realize the light transmission of the colored glaze glass. For the production of light-transmitting colored glaze glass, the silk screen printing method is generally used. However, when the silk screen printing method is used to produce light-transmitting colored glaze glass, the adhesion of the glaze layer to the glass is insufficient, and there are too many light leakage points. SUMMARY

[0004] The present application provides a production method of light-transmitting and firm colored glaze glass and the light-transmitting and firm colored glaze glass. The surface of the glass substrate is sequentially subjected to argon plasma treatment and oxygen plasma treatment, so that the glaze layer is firmly combined with the surface of the glass substrate after drying and steeling treatment, and has strong adhesion. In addition, the present application can reduce the generation of light leakage points and mottling, and can maintain high light transmission performance of the obtained colored glaze glass.

[0005] To achieve the above object, the present application is implemented by the following technical scheme:

[0007] S1: slicing, edge grinding and cleaning the float glass to obtain a glass substrate;

[0008] S2: subjecting one side surface of the glass substrate to argon plasma treatment and then to oxygen plasma treatment to obtain a single-sided plasma-modified glass substrate;

[0009] S3: printing the glaze on the modified surface of the single-sided plasma-modified glass substrate by using the silk screen printing process, and the area of the glass substrate on which the glaze is not printed accounts for more than 1 / 5 of the single-sided area of the glass substrate; and then performing drying treatment;

[0010] S4: subjecting the glass obtained in step S3 to steeling treatment.

[0011] Preferably, the argon plasma treatment is performed at a power of 500-700W for 10-15min.

[0012] Preferably, the oxygen plasma treatment is performed at a power of 400-500W for 15-20min.

[0013] Preferably, in step S3, the screen printing screen mesh is 200-300 mesh.

[0014] The viscosity of the glaze is 80-150dpa·s.

[0015] The drying treatment is performed at a temperature of 150-160℃.

[0016] Preferably, in step S4, the glass substrate is heated for 50-60s / mm according to the thickness of the glass substrate in step S1, and the tempering treatment is performed at a temperature of 600-630℃.

[0017] Preferably, step S3 comprises the following steps: coating the one side of the glass substrate after the drying treatment with a layer of silica sol, and then performing a drying treatment.

[0018] Preferably, the coating amount of the silica sol is 0.05-0.08kg / m 2 .

[0019] Preferably, the preparation method of the silica sol comprises the following steps:

[0020] adding tetraethyl orthosilicate and methyl triethoxysilane into anhydrous ethanol, stirring and mixing, then adding water and stirring for 20-30min, then adding ammonia, continuing to stir for 1-1.5h after the addition is completed, and then aging under sealed conditions, with an aging temperature of 25-30℃ and an aging time of 7-8days;

[0021] The volume ratio of the tetraethyl orthosilicate, the methyl triethoxysilane, the anhydrous ethanol, the ammonia and the water is 5.5-7:1.5-2:35-40:0.7-0.9:1, and the concentration of the ammonia is 25-28wt%.

[0022] Preferably, the drying treatment is performed at a temperature of 150-160℃.

[0023] As a general inventive concept, the present application also provides a light-transmitting and firm colored glaze glass prepared by the above production method.

[0024] The present application has the following advantages:

[0025] 1. This invention, by sequentially treating the surface of a glass substrate with argon plasma and then with oxygen plasma, significantly enhances the surface roughness of the glass substrate in terms of its microstructure. This effectively strengthens the adhesion between the glass substrate surface and the glaze layer, without affecting the flatness and smoothness of the glaze layer. Furthermore, the oxygen plasma treatment enriches the active groups on the glass substrate surface. These active groups interact with the glaze, further strengthening the adhesion between the glaze and the glass substrate surface. This invention, through sequentially treating the surface of the glass substrate with argon plasma and then with oxygen plasma, strengthens the physical and chemical adhesion between the glass substrate surface and the glaze layer. After drying and tempering, the glaze layer is firmly bonded to the glass substrate surface, exhibiting strong adhesion and reducing the generation of light leakage points and blemishes.

[0026] 2. This invention involves coating a layer of silica sol onto the surface of a glass substrate with printed glaze. Combined with its own drying process and the tempering process of colored glaze glass, a thin layer of silica can be formed on the side of the colored glaze glass with the glaze layer. This protects the glaze layer and enhances the adhesion between the glaze layer and the glass substrate. Due to the protection of this thin layer of silica, the glaze layer is less prone to discoloration and will not fade after long-term use. However, the addition of this process will increase the number of light leakage points to some extent.

[0027] 3. The production method of the present invention can produce 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. Detailed Implementation

[0084] The light leakage points, mottling, pattern integrity and adhesion glass performance of the products in the Example 1, 3, 6 and the Comparative Example 1 are detected according to the method in the JCT1006-2006-Enamelled Steel and Enamelled Semi-steel Glass. The specific detection method of the adhesion glass performance is as follows: 3 pieces of products are prepared as samples, a single-edged blade is repeatedly scraped 20 times in a 25 mm*75 mm area on the glass enamel layer, and the blade is at an angle of 45° with the sample. A line is drawn along the 75 mm direction with water, and after 15 minutes of drawing, the line is wiped with fine polishing paste; under the illumination of a scattering light source, the enamel layer is observed with naked eyes to see whether there is ink residue; if there is ink residue, it indicates that the fine pores on the enamel will cause water penetration, thus possibly leading to the discoloration of the enamel layer or the separation of the enamel layer from the glass substrate in icy weather.

[0086]

[0087] Note: S is the glass substrate in units of m 2 .

[0088] As shown in Table 1, the colored enamel glass prepared in the examples has only light leakage points with a diameter of ≤0.5 mm, and the light leakage points are not concentrated, and no mottling can be observed under 600 cm backlight observation, the pattern integrity is high, and the adhesion glass performance is excellent. As compared with the Example 6 and the Example 3, it is known that the re-coating of a layer of silica sol on the glass substrate surface on which the enamel is printed will increase the light leakage points to some extent, but does not affect the colored enamel glass to reach the application standard.

[0089] As compared with the Comparative Example 1 and the Example 3, it is known that if the glass substrate is not subjected to argon plasma treatment and oxygen plasma modification, the light leakage points will obviously increase, mottling will be generated, and the adhesion glass performance will also obviously decrease.
