Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, and in particular to a tempered high-temperature transparent glass glaze and a preparation method and application thereof. Background Art

[0002] At present, in the field of BIPV (building integrated photovoltaic), high-temperature transparent glazes are widely used for the surface treatment of photovoltaic glass. This glaze can be sintered at high temperature to form a transparent protective film, which improves the weather resistance and corrosion resistance of photovoltaic modules. However, the high-temperature transparent glazes currently used have the following problems: (1) High sodium oxide content: The sodium oxide content of the existing high-temperature transparent glaze is about 8%. Although it can ensure a certain light transmittance, the excessive sodium oxide content will cause the performance of photovoltaic modules to decay under certain conditions. (2) Insufficient anti-PID decay performance: During operation, photovoltaic modules are easily affected by potential induced decay (PID). When the current high-temperature transparent glaze is tested for anti-PID decay (85°C, 85% RH, -1500V, 192h), the decay rate is about 4.5%. In addition, some modules were damaged during the test, indicating that the PID decay rate of the existing high-temperature transparent glaze is high and cannot meet the needs of long-term stable operation of photovoltaic modules. (3) Insufficient acid resistance: The current high-temperature transparent glaze is easily corroded in an acidic environment and does not have good acid resistance, which limits its application in certain special environments, such as the seaside, chemical plants and other highly corrosive areas. (4) Poor tempering tolerance of acid-resistant glaze: In order to improve the acid resistance of high-temperature transparent glaze, researchers have developed an acid-resistant glaze. However, this acid-resistant glaze has poor tolerance during the tempering process, that is, in the temperature range of 680-720℃, different color hues will appear when tempered at different temperatures, affecting the appearance and performance of photovoltaic modules.

[0003] Therefore, the existing high temperature transparent glaze has deficiencies in anti-PID attenuation, acid resistance and tempering tolerance, and needs to be improved. In view of this, it is necessary to provide an improved temperable high temperature transparent glass glaze and its preparation method and application to solve the above problems. Summary of the invention

[0004] In view of the technical problems existing in the background technology, the present application provides a temperable high-temperature transparent glass glaze and its preparation method and application, aiming to solve the technical problems of insufficient performance of high-temperature transparent glaze in terms of anti-PID attenuation, acid resistance and tempering tolerance.

[0005] In a first aspect, the present application provides a method for preparing a tempered high-temperature transparent glass glaze, comprising the following steps:

[0006] S1. Add the component materials of the glass powder into a mixer and mix them evenly to obtain a mixture; the component materials of the glass powder include, by mass percentage: 30-40% silicon dioxide, 1-5% aluminum oxide, 8-10% boron oxide, 35-45% bismuth oxide, 1-5% sodium oxide, 1-5% lithium oxide, 2-6% titanium dioxide, 0.5-2% calcium oxide and 1-3% zinc oxide, and the sum of the components is 100%;

[0007] S2. adding the mixture obtained in step S1 into a furnace, first preheating it, and then melting it to obtain molten glass;

[0008] S3. The glass liquid obtained in step S2 is water quenched to obtain a granular glass frit;

[0009] S4. The granular glass frit obtained in step S3 is dried and ball-milled to obtain glass powder;

[0010] S5. The glass powder obtained in step S4 is sieved, powder larger than 10 μm is collected and step S4 is repeated to obtain a glass powder;

[0011] S6. The component materials of the varnish are mixed evenly, and the vitreous powder obtained in step S5 is added and mixed evenly to obtain a slurry;

[0012] S7. The slurry obtained in step S6 is mixed and ground to obtain a tempered high-temperature transparent glass glaze.

[0013] In the technical solution of the embodiment of the present application, by optimizing the component materials of the glass powder, the anti-attenuation performance of the final glaze can be significantly improved. This means that the prepared photovoltaic module has a lower PID attenuation rate under high temperature, high humidity and electric field, thereby extending the service life of the photovoltaic module. Through the synergistic effect between the components, the final glaze has better corrosion resistance in an acidic environment, which broadens the application range of photovoltaic modules, especially in highly corrosive environments. By accurately controlling the temperature of the furnace and the melting process, as well as subsequent ball milling and screening treatment, a glass glaze with better tempering tolerance can be obtained.

[0014] In some embodiments, the preheating temperature is 550-650° C., and the preheating time is 15-25 min; the melting temperature is 1100-1300° C., and the melting time is 50-70 min.

[0015] In this embodiment, the preheating treatment helps to reduce the temperature gradient inside the material and make the temperature distribution of the entire material more uniform, which is beneficial to the effect of the subsequent melting treatment. The high-temperature melting treatment can ensure that the component materials of the glass powder are fully melted to form a uniform glass liquid, which is beneficial to improving the performance of the final product. By accurately controlling the preheating and melting treatment, a glass glaze with excellent physical and chemical properties can be obtained, such as better heat resistance, transparency and acid and alkali resistance, which are crucial for photovoltaic modules.

[0016] In some embodiments, the material of the ball mill is zirconia, and the ball milling time is 1 to 2 hours.

[0017] In this embodiment, the zirconium oxide ball milling medium has high hardness and wear resistance, and can achieve uniform refinement and dispersion of glass powder in a short time. Fine powder helps to reduce light scattering and improve the transparency of the final product.

[0018] In some embodiments, the mesh number of the sieving process is 1700-1800 mesh. The particle size of the obtained glass powder is less than 10 μm.

[0019] In this embodiment, the screen has very fine meshes, which can effectively separate glass powder with a particle size of less than 10 μm, ensuring that the particle size distribution of the powder is within a very narrow range. By screening with a high-mesh screen, larger particles and impurities can be removed, thereby improving the purity of the powder. Accurately controlled particle size distribution helps optimize the performance of the final product, such as transparency, strength, thermal stability, etc.

[0020] In some embodiments, the component materials of the varnish include, by mass percentage: 60-80% terpineol, 15-25% butyl carbitol, and 5-15% acrylic resin, and the sum of each component is 100%; the mass ratio of the glass powder to the varnish is (70-75):(25-30).

[0021] In this embodiment, these components of varnish can provide good printing performance, ensure that the printing process is carried out smoothly, and reduce printing defects. The mixing of pine alcohol and butyl carbitol can provide appropriate viscosity, so that the varnish can fully wet the glass powder and maintain good fluidity. Acrylic resin, as a binder, helps to improve the dispersibility of glass powder in varnish and prevents powder from agglomerating. Acrylic resin can also enhance the adhesion of varnish to the glass surface, which is conducive to subsequent printing or coating processes. At the same time, acrylic resin can form a protective film on the glass surface, improve the durability and weather resistance of the coating. Selecting an appropriate amount of acrylic resin can ensure that the coating maintains a higher transparency after drying, without affecting the photoelectric conversion efficiency of the photovoltaic module.

[0022] In a second aspect, an embodiment of the present application provides a tempered high-temperature transparent glass glaze, which is prepared by the preparation method of the first aspect.

[0023] In a third aspect, the embodiment of the present application provides a double-glass photovoltaic module, which is composed of a front glass, an adhesive film, a battery cell and a back glass. The surface of the front glass is printed with a film including the temperable high-temperature transparent glass glaze described in the second aspect, and the mass fraction of the temperable high-temperature transparent glass glaze in the film is 75-98wt%. By controlling the proportion of the temperable high-temperature transparent glass glaze, a double-glass photovoltaic module with excellent performance can be obtained.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0032] The sodium oxide content of the high-temperature transparent glaze in the prior art is about 8%. The test component is PID-resistant (85°C, 85% RH, -1500V, 192h), and the attenuation rate is about 4.5%. In addition, some components were damaged during the test, and the PID attenuation rate was high. The transparent glaze is not acid-resistant and cannot meet the needs of long-term stable operation of photovoltaic components. The tempering tolerance of the acid-resistant glaze is poor, and different color hues will appear when tempered at different temperatures, affecting the appearance and performance of the photovoltaic components.

[0033] In order to solve the technical problems that high-temperature transparent glazes have insufficient performance in terms of anti-PID attenuation, acid resistance and tempering tolerance, the present application provides a temperable high-temperature transparent glass glaze and a preparation method and application thereof, wherein, by optimizing the component materials of the glass powder, the prepared double-glass photovoltaic module has high transparency, good acid resistance, high tempering tolerance, and strong anti-PID attenuation ability.

[0034] In a first aspect, the present application provides a method for preparing a tempered high-temperature transparent glass glaze, comprising the following steps:

[0035] S1. Add the component materials of the glass powder into a mixer and mix them evenly to obtain a mixture; the component materials of the glass powder include, by mass percentage: 30-40% silicon dioxide, 1-5% aluminum oxide, 8-10% boron oxide, 35-45% bismuth oxide, 1-5% sodium oxide, 1-5% lithium oxide, 2-6% titanium dioxide, 0.5-2% calcium oxide and 1-3% zinc oxide, and the sum of the components is 100%;

[0036] S2. adding the mixture obtained in step S1 into a furnace, first preheating it, and then melting it to obtain molten glass;

[0037] S3. The glass liquid obtained in step S2 is water quenched to obtain a granular glass frit;

[0038] S4. The granular glass frit obtained in step S3 is dried and ball-milled to obtain glass powder;

[0039] S5. The glass powder obtained in step S4 is sieved, powder larger than 10 μm is collected and step S4 is repeated to obtain a glass powder;

[0040] S6. The component materials of the varnish are mixed evenly, the vitreous powder obtained in step S5 is added, and the mixture is mixed evenly at a speed of 500 to 550 r / min to obtain a slurry;

[0041] S7. The slurry obtained in step S6 is mixed and ground by a two-roll grinder at a rotation speed of 1800 to 2100 r / min to obtain a tempered high-temperature transparent glass glaze.

[0042] By precisely mixing the different chemical components, a glass glaze is prepared that remains transparent at high temperatures and has good performance during the tempering process. The components interact during the melting, quenching, drying, ball milling and screening processes to form a glass glaze with excellent physical and chemical properties.

[0043] Furthermore, in some embodiments, the temperature of the preheating treatment is 550-650° C., and the preheating time is 15-25 min. The temperature of the melting treatment is 1100-1300° C., and the melting time is 50-70 min.

[0044] In the technical solution of the embodiment of the present application, the purpose of the preheating treatment is to slowly heat the material to a certain temperature to reduce the stress inside the material and prevent the generation of cracks. The melting treatment temperature range and time period ensure that the material can be fully melted and help to improve the uniformity and purity of the material.

[0045] Furthermore, in some embodiments, the ball mill material is zirconia, the ball milling time is 1 to 2 hours, the mesh number of the sieving treatment is 1700 to 1800 mesh, and the particle size of the obtained glass powder is less than 10 μm.

[0046] Glass powder with a particle size of less than 10 μm can ensure high transparency and uniform component distribution in the final product.

[0047] Furthermore, in some embodiments, the component materials of the varnish include, by mass percentage, 60-80% terpineol, 15-25% butyl carbitol, and 5-15% acrylic resin, and the sum of the components is 100%. The mass ratio of the vitreous powder to the varnish is (70-75): (25-30), preferably 72:28.

[0048] In the technical scheme of the embodiment of the present application, pine alcohol helps to dissolve and stabilize other ingredients, butyl carbitol is used to improve the fluidity and stability of the mixture, and also helps to improve the surface finish of the final product, and acrylic resin can improve the viscosity and adhesion of the mixture, which helps the uniform dispersion of glass powder in the glaze. The ratio of vitreous powder and varnish ensures that the glass powder can be well dispersed and stable in the varnish, thereby preparing a uniform, high-quality glaze. A higher ratio of glass powder helps to improve the thermal stability and mechanical properties of the glaze, and the varnish ensures the processability and applicability of the glaze. By accurately controlling these components and ratios, a glass glaze with ideal performance can be prepared, which can provide good transparency, heat resistance and tempering performance when applied to ceramics, glass or other substrate materials.

[0052] The tempered high-temperature transparent glass glaze is evenly mixed with pearlescent powder, structural color powder and color ink, and coated on the glass surface by screen printing. The wet film thickness is 15-25μm. After baking, curing and high-temperature tempering, a colored BIPV front glass is obtained. The mass ratio of the tempered high-temperature transparent glass glaze, pearlescent powder, structural color powder and color ink is (60-90): (1-20): (1-20): (0-10); the curing temperature is 170-200℃, and the curing time is 3-8min; the tempering temperature is 680-720℃, and the tempering time is 120-150s; the front glass is made into a double-glass component through a stacking and laminating process, and the stacking is front glass-film-cell-film-back glass.
