Description

Technical Field

[0001] The present invention belongs to the technical field of inks, and particularly relates to composite photovoltaic glass inks, highly transparent colored glass panels, and photovoltaic modules. Background Art

[0002] China is the world's largest photovoltaic power generation market. As a renewable energy source, photovoltaic power generation has great potential in reducing carbon emissions and achieving sustainable development. With the continuous development of new energy and the increasing demand for urban energy conservation, emission reduction, and environmental protection, the integration of solar energy into buildings has increasingly become a new trend in solar energy application and power generation.

[0003] Building-integrated photovoltaic (BIPV) is a new concept for applying solar power generation. It installs a solar photovoltaic power generation array on the surface of a building to provide electricity. It makes full use of the surface space of the building and realizes the perfect combination of the building and renewable energy. This design method is environmentally friendly, energy-saving, and reduces consumption, improving the utilization rate of energy and having broad application prospects.

[0004] The BIPV solar photovoltaic module, which adopts a double-glass photovoltaic module, is a composite structure composed of two pieces of tempered glass. The internal interlayer is a PVB film, and a photovoltaic cell is laminated. The module structure is front plate glass 100, PVB film 400, cell 200, PVB film 400, and back plate glass 300. See the attached description Figure 2 .

[0005] In the photovoltaic module structure, the solar photovoltaic cell is in the core position and plays a key role. It is a semiconductor device that uses the photovoltaic effect of materials to convert solar energy into electrical energy. In the current photovoltaic industry, the cell mainly has several types such as crystalline silicon solar cells, perovskite solar cells, and thin-film solar cells. Most of them are dark blue, dark brown, and black in appearance. The glass material and PVB film in the module are both in a transparent state. Therefore, the finally formed and pressurized solar module has a single dark blue-black appearance, and the overall tone is dull and monotonous, affecting the aesthetics of the building and making it difficult to meet the aesthetic requirements for building-integrated photovoltaic (BIPV).

[0006] For traditional ordinary curtain walls, commonly used colored coatings are sintered onto the glass surface at a high temperature. The coating needs to be sintered onto the glass surface at 650 - 750 °C. This process is cumbersome, has high requirements for equipment and operation, and after sintering, the coating has low light transmittance, insufficient color saturation and brightness, and a dull visual effect. More critically, it is difficult to form a firm bonding interface between the sintered coating and the PVB film layer in the photovoltaic module, and the bonding force is weak, which cannot meet the performance requirements of BIPV photovoltaic buildings.

[0007] With the rapid development of urban construction, the aesthetic requirements for building-integrated photovoltaics are also higher. Building designers and property owners have high demands for the colors of photovoltaic building materials. How to break through the single blue-black appearance of traditional photovoltaic modules, meet the aesthetic requirements of BIPV buildings, satisfy the power generation requirements of BIPV buildings, and at the same time meet the safety performance requirements of BIPV buildings, and develop decorative colored BIPV photovoltaic modules has become an urgent problem to be solved.

[0041] For the composite coatings prepared in Examples 1-3 and Comparative Examples 1-3, the light transmittance was measured in accordance with GB / T 2680-1994; the adhesion to the PVB film layer was measured in accordance with GB / T 2790-1995; the adhesion test was measured in accordance with GB 1720-1979; the salt spray test was measured in accordance with GB / T 1771-1979; and the sequence aging was carried out according to the sequence aging of UV15kwh / m 2 in IEC61215:2005, thermal cycling 50 times, and wet freeze 10 times; the double 85 aging and UV200kwh / m2 condition aging were both aged in accordance with the requirements of IEC61215:2005.

[0042] The test and detection data of Examples 1-3 and Comparative Examples 1-3 are shown in the following table:

[0043] Table 1: Result comparison of Examples 1-3 and Comparative Examples 1-3

[0044] Test Items Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Appearance Color Red Blue Purple Red Blue Purple Damp Heat Resistance Qualified Qualified Qualified Unqualified Unqualified Unqualified Adhesion (Cross-Cut Test) 0 0 0 2 2 3 Salt Spray Resistance Qualified Qualified Qualified Unqualified Unqualified Unqualified Weather Resistance Qualified Qualified Qualified Unqualified Qualified Unqualified Light Transmittance 85％ 90％ 92％ 82％ 88％ 90％ PVB Film 400 Peel Strength 75 N / m 82 N / m 85 N / m 72 N / m 25 N / m 15 N / m

[0045] In the adhesion test, grade 0 indicates the strongest adhesion, and grade 5 indicates the weakest adhesion. The adhesion gradually decreases from grade 0 to grade 5.

[0046] The test results show that the resins used in Examples 1-3 are silicone-modified polyester resins, and the resins used in Comparative Examples 1-3 are saturated polyester resins. The change in the resin has little effect on the color, and all can form colored glass panels with high light transmittance. As can be seen from the table, in Comparative Example 1, the A ink resin was changed to a saturated polyester resin, and the B ink composition remained unchanged. The peeling rate of the PVB film of the coating was 72 N / m, the adhesion of the coating was grade 2, and the weather resistance, salt spray resistance, and damp heat resistance were all unqualified, indicating that the silicone-modified polyester resin in the A ink has a greater impact on the adhesion, damp heat resistance, salt spray resistance, and weather resistance of the coating, and has little impact on the peeling rate of the PVB film; in Comparative Example 2, the A ink composition remained unchanged, and the B ink resin was changed to a saturated polyester resin. The adhesion of the coating was grade 2, the weather resistance was qualified, and the damp heat resistance and salt spray resistance were all unqualified. The peeling rate of the PVB film was only 25 N / m, indicating that the silicone-modified polyester resin in the B ink has a greater impact on the peeling rate, adhesion, damp heat resistance, and salt spray resistance of the PVB film, and has little impact on the weather resistance; in Comparative Example 3, the resins of both A ink and B ink were changed to saturated polyester resins. The test results showed that the adhesion of the coating was grade 3, the peeling rate of the PVB film was 15 N / m, and the weather resistance, salt spray resistance, and damp heat resistance were all unqualified, unable to meet the use requirements of photovoltaic modules.

[0047] In Examples 1-3, the composite high-transparency photovoltaic glass ink prepared from silicone-modified polyester resin (model 1503 of Hubei Longsheng Sihai New Materials Co., Ltd.) was used for both A ink and B ink, with bright colors, strong light transmittance, the adhesion between the coating and the substrate being grade 0, the peeling rate between the coating and the film reaching over 75 N / m, and the damp heat resistance, salt spray resistance, and weather resistance all being qualified, which can meet the use requirements of photovoltaic modules.

[0048] Among them, the appearance colors in Examples 1-3 and Comparative Examples 1-3 are all prepared from pearlescent pigments and can be adjusted in color by themselves. Ink A uses functional pearlescent pigments. Pearlescent pigments have extremely strong decorative effects. Pearlescent pigments are new pigments produced by covering natural mica flakes with metal oxides. Because of their flaky structure and the high refractive index of metal oxides, when light is incident, reflection, refraction, and interference will occur at different interfaces, producing a unique pearlescent effect. Pearlescent pigments have good transparency, stable materials, and good dispersibility. When added to a transparent substrate, they can produce a pearl-like luster and good light transmittance. Changing the thickness or type of metal oxide will change the color of the pearlescence. Adding pearlescent pigments to Ink A can make the coating have color diversity and light transmittance, ensure the photoelectric conversion performance of the BIPV module, and meet the aesthetic design requirements of different buildings. And the pearlescent pigment is preferably 8-15 parts, and the color is relatively bright and full. When the amount of the pearlescent pigment is less than 8 parts, the color of the formed coating is lighter, the luster is dim, and the power generation battery cannot be covered; when the amount of the pearlescent pigment is greater than 15 parts, the ink is too viscous, the fluidity is poor, which affects the light transmittance of the coating, and then affects the power generation effect of the module, and also affects the adhesion between the coatings.

[0049] Among them, compared with Comparative Examples 1-3, Examples 1-3 can meet higher requirements in terms of overall damp heat resistance, salt spray resistance, and weather resistance. Moreover, when using the inks in Examples 1-3, the peel strength of the PVB film 400 can reach more than 75 N / m, ensuring that when using the composite photovoltaic glass ink in Examples 1-3, it has a high adhesive force. That is, when using isocyanate adduct as the curing agent in Ink B120 and the film layer is the PVB film 400 layer, because the isocyanate group (-NCO) of the isocyanate adduct can react chemically with active hydrogen groups such as hydroxyl groups (-OH) contained in the PVB film molecules, covalent bonds are formed by sharing electrons between atoms, effectively enhancing the chemical bond and physical adsorption between the ink coating and the PVB, making the two firmly connected. The organosilicon-modified polyester resin contains hydroxyl functional groups, and the hydroxyl functional groups have strong adhesion to glass and metal, so that the cured paint coating not only has high adhesion on the substrate, but also has high adhesion to the PVB film layer.

[0050] The Si-O bonds contained in the silicone-modified polyester resin have good ultraviolet absorption and scattering capabilities, which can reduce the direct damage of ultraviolet rays to the ink coating. Moreover, the chemical structure of the silicone-modified polyester resin is stable and not easily decomposed by ultraviolet rays, which helps to improve the ultraviolet aging resistance of the material. The combination of the functional pearlescent pigment and the silicone-modified polyester resin ensures that Ink A110 has good weather resistance and light transmittance while achieving color functions. The solvent can dilute the ink, adjust the viscosity, improve the leveling property of the coating, and control the thickness of the preset film formed by the ink on the substrate. The mass of the solvent is 20-30 parts. If the solvent content is less than 20 parts, the resin material cannot be dissolved, resulting in uneven coating thickness. If the solvent content is higher than 30 parts, the viscosity of the ink decreases, resulting in uncontrollable coating thickness.

[0051] The coatings of Ink A110 and Ink B120 are stably combined through physical adsorption, chemical bonding, and diffusion. A large number of hydroxyl groups in the silicone-modified polyester resin 1503 in Ink B120 form hydrogen bonds with a large number of hydroxyl groups in the silicone-modified polyester resin 1503 in Ink A110. The isocyanate adduct in Ink B120 can react chemically with the hydroxyl groups in Ink A110 and the active groups in the silane coupling agent OFS6040 to form covalent bonds. In addition, during the heat curing process of Ink B120, the polyester molecular chain segments in the silicone-modified polyester resin will diffuse to the surface of the Ink A110 coating and penetrate each other. Through the above three mechanisms, Ink B120 and Ink A110 are stably combined together.

[0052] The n-butyl etherified amino resin contains multiple reactive active groups. In the Ink A110 system, it can crosslink with the hydroxyl groups of the silicone-modified polyester resin to form a three-dimensional network structure, making the coating cure into a film and improving the properties such as hardness, water resistance, and chemical corrosion resistance of the coating. It can reduce the baking temperature and baking time of Ink A110, and precisely control the curing speed and degree to meet different construction and use requirements.

[0053] In addition, the coating method of the high-transparency colored glass panel 100 is as follows:

[0054] Prepare Ink A110 by mixing the components of Ink A110 in proportion and then stirring evenly at high speed;

[0055] Prepare Ink B120 by mixing the components of Ink B120 in proportion and then stirring evenly at high speed;

[0056] Secondary coating: Coating ink A110 on the surface of the glass panel 100, followed by drying and curing treatment. The heating and curing temperature is 100 - 200 degrees Celsius, and the heating and drying time is 5 - 15 minutes to form a colored light-transmitting coating. Then, coat ink B120 on this colored light-transmitting coating and perform drying and curing treatment. The heating and curing temperature is 180 - 250 degrees Celsius, and the heating and drying time is 5 - 25 minutes to form a light-transmitting coating.

[0057] Among them, the coating process of ink A110 and ink B120 can use screen printing, which is applied to the surface of the glass substrate. The screen used has a mesh size of 100 - 300 meshes, a wire diameter of 20 - 50 microns, and a screen tension of 20 - 30 N / cm. It can also be applied by spraying, roll coating, curtain coating, etc. The shape and color of the coating are not restricted. It can be made into a single pure color or designed into a specific pattern (the pattern can be selected from dots, lines, surfaces, or irregular shapes) and can be selected according to actual needs.

[0058] The total thickness of the coatings of ink A110 and ink B120 is 15 - 25 μm. Among them, ink A110 is screen-printed through a 200-mesh screen to obtain a coating with a thickness of about 9 - 11 μm, and ink B120 is screen-printed through a 200-mesh screen to obtain a coating with a thickness of about 9 - 11 μm.

[0059] In addition, the photovoltaic module includes a power generation battery 200, a front plate glass 100, and a back plate glass 300. The upper end of the power generation battery 200 is connected to the front plate glass through a PVB film 400, and the lower end of the power generation battery 200 is connected to the back plate glass 300 through a PVB film 400. The front plate glass is the high-transparency colored glass panel 100. That is, the composite photovoltaic glass ink of the present application can be applied to the high-transparency colored photovoltaic glass panel 100, and the high-transparency colored photovoltaic glass panel 100 can be applied to the photovoltaic module. The composite photovoltaic glass ink of the present invention can also be used for printing various glass substrates, such as home appliance glass panels, charging pile panels, mobile phone panels, etc.

[0060] The above embodiments are exemplary and should not be construed as limiting the present invention. For those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
