Description

Technical Field

[0001] The present invention relates to the technical field of glass preparation, and particularly relates to a double-sided inorganic material glass panel and a preparation method thereof. Background Art

[0002] At present, for the decorative panels with a positive three-dimensional touch on the market, the back paint is low-temperature baked solvent-based ink. Although it has certain advantages in color and texture, the low-temperature baked ink has certain defects in adhesion and hardness, and cannot form a permanent adhesion, so it cannot be applied to products such as cooktops and range hoods in the kitchen appliance industry. Most of the products applied in the kitchen appliance industry are plain glass panels without any coating on the front and a high-temperature protection bottom on the back. However, this kind of product has a single style and cannot meet the real interactive experience of users' vision and touch.

[0003] In addition, in the prior art, when using ordinary inorganic materials for toughening, the materials will melt and sinter on the ceramic rollers, causing damage to the ceramic rollers and the product coating.

[0004] In view of this, it is necessary to design an improved double-sided inorganic material glass panel and a preparation method thereof to solve the above problems. Summary of the Invention

[0005] In view of the technical problems existing in the background art, the present application provides a double-sided inorganic material glass panel and a preparation method thereof. The double-sided inorganic material glass panel not only satisfies the double-sided decoration effect, but also forms a double-sided inorganic toughened permanent adhesion coating, improving the anti-resistant performance of the glass coating, with rich and diverse styles, and meeting the real interactive experience of users' vision and touch.

[0006] In a first aspect, an embodiment of the present application provides a preparation method of a double-sided inorganic material glass panel, including the following steps:

[0007] S1, cutting, grinding and cleaning the glass;

[0008] S2, printing a high-temperature ink pattern on the back of the glass cleaned in step S1, and then printing a high-temperature ink protection bottom on the high-temperature ink pattern;

[0009] S3, performing semi-toughening treatment on the glass obtained in step S2, with a heating temperature of 700 - 720 °C, a heating time of 80 - 300 s, and a rapid cooling air pressure of less than or equal to 35%;

[0010] S4, cleaning the glass obtained in step S3, and then printing a high-temperature ink pattern on the front of the glass;

[0011] S5, performing toughening treatment on the glass obtained in step S4, with a rapid cooling air pressure of 55% - 95%, to obtain a double-sided inorganic material glass panel.

[0012] In the technical solution of the embodiment of the present application, by first performing semi-tempering treatment on the glass with high-temperature printing on the back, the glass can meet the physical and chemical property requirements such as particle size, curvature, and transparency; then performing high-temperature printing on the front of the glass, and finally performing tempering treatment; by reasonably controlling the process parameters of the semi-tempering treatment and the tempering treatment, a double-sided inorganic tempered permanent adhesion coating is formed, improving the anti-resistant performance of the glass coating, and the obtained double-sided inorganic material glass panel has rich and diverse styles, meeting the real interactive experience of the user's vision and touch.

[0013] In some embodiments, in step S5, when tempering the glass, the heating temperature is 680 - 700 °C, and the heating time is 80 - 300 s.

[0014] In some embodiments, in step S2, after printing the high-temperature ink pattern with a 200 - 300 mesh screen and drying, then printing the high-temperature ink protection base with a 150 - 200 mesh screen and drying, the heating temperature is 700 - 720 °C, and the heating time is 80 - 300 seconds.

[0015] In some embodiments, the melting point of the high-temperature ink used in step S2 is higher than the melting point of the high-temperature ink used in step S4, and the melting point difference between the two is 18 - 21 °C.

[0016] Specifically, the components of the high-temperature ink used in step S2, by mass percentage, include 25% - 35% of ink oil, 15% - 30% of inorganic pigment, and 35% - 60% of anti-sticking glass powder; the components of the high-temperature ink used in step S4, by mass percentage, include 25% - 35% of ink oil, 15% - 30% of inorganic pigment, and 35% - 60% of ordinary glass powder.

[0017] In the technical solution of the embodiment of the present application, ordinary glass powder is used for front printing and anti-sticking glass powder is used for back printing, so that the melting point of the high-temperature ink used for back printing is about 20 °C higher than the melting point of the high-temperature ink used for front printing. With such a setting, during tempering treatment, the glass powder in the front material is in a molten state and becomes soft and sticky at high temperature; the glass powder in the back material can undergo a crystallization reaction at high temperature to form crystals, reducing the surface stickiness and not damaging the ceramic roller; solving the technical problem in the prior art that the material will melt and sinter on the ceramic roller during tempering, causing damage to the ceramic roller and the product coating.

[0018] In some embodiments, in step S4, after tempering the glass, it is cleaned, and a high-temperature ink pattern is printed on the front of the glass with a 200 - 300 mesh screen.

[0019] In a second aspect, an embodiment of the present application provides a double-sided inorganic material glass panel, which is prepared by using the preparation method of the double-sided inorganic material glass panel described in any one of the above.

[0020] The double-sided inorganic material glass panel includes a high-temperature texture layer, a glass substrate layer, a high-temperature topcoat layer, and a high-temperature protection bottom layer, which are arranged in sequence from top to bottom.

[0021] In some embodiments, the thickness of the high-temperature texture layer is 15 - 45 μm, the thickness of the glass substrate layer is 2 - 12 mm, the thickness of the high-temperature topcoat layer is 15 - 25 μm, and the thickness of the high-temperature protection bottom layer is 25 - 35 μm.

[0022] In some embodiments, the light transmittance of the double-sided inorganic material glass panel is greater than or equal to 80, the curvature is less than or equal to 0.3, and the granularity is 30 - 120.

In order to be able to understand the technical means of the present application more clearly, it can be implemented according to the content of the specification.

[0030] In the prior art, most of the glass panel products applied in the kitchen appliance industry are plain glass panels without any coating on the front side and a high-temperature protection bottom on the back side. Such products have a single style and cannot meet the real interactive experience of users' vision and touch.

[0031] The present application provides a method for preparing a double-sided inorganic material glass panel, comprising the following steps:

[0032] S1, cutting, grinding and cleaning the glass;

[0033] S2, printing a high-temperature ink pattern on the back side of the glass cleaned in step S1, and then printing a high-temperature ink protection bottom on the high-temperature ink pattern;

[0034] Among them, after printing the high-temperature ink pattern with a 200-300 mesh screen and drying, then printing the high-temperature ink protection bottom with a 150-200 mesh screen and drying, the heating temperature is 700-720 °C, and the heating time is 80-300 seconds.

[0035] The components of the high-temperature ink, by mass percentage, include 25%-35% of ink oil, 15%-30% of inorganic pigment, and 35%-60% of glass powder.

[0036] S3, performing semi-tempering treatment on the glass obtained in step S2, with a heating temperature of 700-720 °C, a heating time of 80-300 s, and a rapid cooling air pressure of less than or equal to 35%;

[0037] S4, cleaning the glass obtained in step S3, and then printing a high-temperature ink pattern on the front side of the glass;

[0038] In step S4, after cleaning the front side of the glass, print the high-temperature ink with a 200-300 mesh screen;

[0039] S5. Temper the glass obtained in step S4 with an air pressure of the rapid cooling air being 55% - 95% to obtain a double-sided inorganic material glass panel.

[0040] Among them, when tempering the glass, the heating temperature is 680 - 700 °C and the heating time is 80 - 300 s.

[0041] In the present invention, first, high-temperature printing is performed on the back surface of the glass, and then semi-tempering treatment is carried out, so that the glass can meet the physical and chemical performance requirements such as particle size, curvature, and transparency; then high-temperature printing is performed on the front surface of the glass, and finally tempering treatment is carried out to form a double-sided inorganic tempered permanent attachment coating, improving the anti-resistant performance of the glass coating. The obtained double-sided inorganic material glass panel has a rich variety of styles, meeting the real interactive experience of users' vision and touch.

[0042] In this preparation method, the melting point of the high-temperature ink used in step S2 is higher than that of the high-temperature ink used in step S4, and the melting point difference between the two is 18 - 21 °C. By controlling the use of ordinary glass powder for front printing and anti-sticking glass powder for back printing, the melting point of the high-temperature ink used for back printing is about 20 °C higher than that of the high-temperature ink used for front printing. With such a setting, during the tempering treatment, the glass powder inside the front material is in a molten state and becomes soft and sticky at high temperature; the glass powder inside the back material can undergo a crystallization reaction at high temperature to form crystals, reducing the surface stickiness and not damaging the porcelain roller; solving the technical problems in the prior art that the material will melt and sinter on the porcelain roller during tempering, causing damage to the porcelain roller and the product coating.

[0043] Specifically, the components of the high-temperature ink used in step S2, by mass percentage, include 25% - 35% of ink oil, 15% - 30% of inorganic pigments, and 35% - 60% of anti-sticking glass powder; the components of the high-temperature ink used in step S4, by mass percentage, include 25% - 35% of ink oil, 15% - 30% of inorganic pigments, and 35% - 60% of ordinary glass powder.

[0044] In a second aspect, an embodiment of the present application provides a double-sided inorganic material glass panel, which is prepared by using the preparation method of the double-sided inorganic material glass panel described above. The double-sided inorganic material glass panel includes a high-temperature texture layer, a glass substrate layer, a high-temperature topcoat layer, and a high-temperature protective bottom layer arranged in sequence from top to bottom, and its product structure is as Figure 1 shown.

[0045] The thickness of the high-temperature texture layer is 15 - 45 μm, the thickness of the glass substrate layer is 2 - 12 mm, the thickness of the high-temperature topcoat layer is 15 - 25 μm, and the thickness of the high-temperature protective bottom layer is 25 - 35 μm.

It not only meets the performance requirements of kitchen appliances, but also satisfies the real interactive experience of users' vision and touch.

[0047] Some specific embodiments are listed below. It should be noted that the embodiments described below are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0048] Example 1

[0049] This example provides a preparation method for a double-sided inorganic material glass panel, which includes the following steps:

[0050] S1, cutting, grinding and cleaning the glass; the glass size is 549.6mm * 439.5mm * 3.2mm;

[0051] S2, after cleaning the back of the glass in step S1, printing high-temperature ink patterns with a 200 - 300 mesh screen and then drying, and then printing a high-temperature ink protection base with a 200 mesh screen and drying; among them, the components of the high-temperature ink include 35% ink oil, 30% inorganic pigment, and 35% anti-sticking glass powder.

[0052] S3, semi-tempering the printed glass in step S2, with a heating temperature of 700 °C, a heating time of 120 seconds, and a rapid cooling air pressure of 30%;

[0053] S4, cleaning the tempered glass in step S3, and then printing high-temperature ink patterns on the front of the glass with a 200 - 300 mesh screen and drying; among them, the components of the high-temperature ink include 35% ink oil, 30% inorganic pigment, and 35% ordinary glass powder.

[0054] S5, tempering the printed glass in step S4, with a heating temperature of 680 °C, a heating time of 120 seconds, and a rapid cooling air pressure of 95%.

[0055] Examples 2 - 4 and Comparative Examples 1 - 4

[0056] Examples 2 - 4 provide a preparation method for a double-sided inorganic material glass panel. Compared with Example 1, the differences lie in changing the process parameters of the semi-tempering treatment in step S3 and the process parameters of the tempering treatment in step S5. The specific details are shown in Table 1. The rest are roughly the same as those in Example 1 and will not be elaborated here.

[0057] Table 1 Parameter settings of Examples 1 - 4 and Comparative Examples 1 - 4

[0058]

[0059]

[0060] Comparative Example 5

[0061] Comparative Example 5 provides a method for preparing a double-sided inorganic material glass panel. Compared with Example 1, the difference lies in that in step S3, full tempering treatment is carried out instead of semi-tempering. The process parameters of the full tempering treatment are: the heating temperature is 680 °C, the heating time is 120 seconds, and the rapid cooling air pressure is 95%. The rest is roughly the same as in Example 1 and will not be elaborated here.

[0062] Examples 5-7

[0063] Examples 5-7 provide a method for preparing a double-sided inorganic material glass panel, and double-sided inorganic material glass panels are prepared using glass substrates of different sizes. The specific process parameters are shown in Table 2.

[0064] Table 2 Parameter settings of Examples 5-7

[0065]

[0066] The double-sided inorganic material glass panel products prepared in Examples 1-7 and Comparative Examples 1-5 were subjected to relevant performance tests. Among them, the granularity refers to the number of fragments within a unit of 50 mm × 50 mm after the glass is broken. The results are shown in the following table; a tempered glass product with a light transmittance of more than 80%, a bending degree within 0.3, and a granularity in the range of 60-100 pieces has better performance.

[0067] Table 3 Tempered glass performance of Examples 1-7 and Comparative Examples 1-5

[0068] Transparency / % Flexure / % Granularity / pcs Example 1 85 0.21 70 Example 2 80 0.15 70 Example 3 80 0.28 90 Example 4 87 0.3 66 Example 5 80 0.15 70 Example 6 85 0.22 90 Example 7 85 0.23 90 Comparative Example 1 85 0.45 65 Comparative Example 2 87 0.32 72 Comparative Example 3 87 0.35 90 Comparative Example 4 76 0.1 47 Comparative Example 5 85 0.31 103

[0069] As can be seen from Table 3, the changes in the tempering time and air pressure will have a certain impact on the light transmittance, bending degree, and granularity of the tempered glass. From Comparative Example 5, it can be seen that when full tempering treatment is carried out after the back printing is completed, due to the too high air pressure, the glass has a large granularity and a large bending degree.

[0070] From Comparative Example 1, it can be seen that when semi-tempering treatment is carried out and the air pressure is higher than 35%, due to the too high air pressure, the glass has a large bending degree.

[0071] From Comparative Example 2, it can be seen that when semi-tempering treatment is carried out and the heating time is less than 80 seconds, due to the short time, the glass has a large bending degree.

[0072] As can be seen from Comparative Example 3, when tempered and the heating temperature is higher than 700 °C, due to the high temperature, the glass has a relatively large grain size and a relatively large degree of curvature.

[0073] As can be seen from Comparative Example 4, when tempered and the wind pressure is lower than 55%, due to the small wind pressure, the glass has a relatively small grain size.

[0074] It should be noted that the present application is not limited to the above embodiments. The above embodiments are only examples, and embodiments having the same structure and the same effect as the technical idea within the technical scope of the present application are included in the technical scope of the present application. In addition, within the scope not departing from the gist of the present application, various modifications that can be conceived by those skilled in the art to the embodiments and other forms constructed by combining some constituent elements of the embodiments are also included in the scope of the present application.
