Description

TECHNICAL FIELD

[0001] The present application relates to the field of color-changing components, in particular to an EC electrochromic component, a curved light-adjusting component and a preparation method thereof. BACKGROUND

[0002] With the gradual development of intelligent color-changing component technology, intelligent color-changing components are gradually applied to the fields of automobile windows, glass curtain walls, etc. At present, the intelligent color-changing components used in the above-mentioned fields are generally flat EC electrochromic components. The structure of the EC electrochromic component generally comprises a first layer of transparent substrate, a first transparent conductive layer, an ion storage layer, an electrolyte layer, an electrochromic layer, a second transparent conductive layer and a second layer of transparent substrate arranged in sequence. It is rarely applied to curved light-adjusting glass, and the reasons are as follows:

[0003] Firstly, the curved light-adjusting glass generally comprises two curved substrate layers, and a glue film layer and an EC electrochromic component arranged in the substrate layers from the outside to the inside. Due to the limitation of the current bending process of the curved substrate layer, the curvatures obtained in the bending process of the substrate layer are difficult to be completely consistent. Therefore, the gap thickness between the two substrate layers is difficult to keep consistent, which leads to the non-uniform thickness of the electrolyte layer in the EC electrochromic component during the laminating process, the inconsistent color-changing speed of the EC electrochromic component at different positions, the inconsistent color depth of the curved light-adjusting glass, and the difficulty to meet the optical quality standard.

[0004] Secondly, the curved light-adjusting glass has high requirements for process precision during the laminating process. The curved substrate needs to be precisely calibrated, and the gap difference between the two substrate layers needs to be constantly adjusted to make the gap difference of the substrate layer at different positions close to consistent, which seriously affects the yield of the curved light-adjusting glass. Therefore, it is difficult to balance the yield and quality of the curved light-adjusting glass.

[0005] Based on the above-mentioned related factors, the related art attempts to set a film on both sides of the electrolyte layer of the electrochromic component in order to maintain the uniform thickness of the electrolyte layer during the laminating process of the curved light-adjusting glass. However, in the actual test process, the present applicant found that: since the substrate layer is curved, the film of the electrochromic component is prone to wrinkles at the periphery during the stretching process, which leads to the water ripples phenomenon of the curved light-adjusting glass during the laminating process, and the yield of the finished product is difficult to improve. Moreover, the electrolyte layer is deformed due to the influence of temperature and pressure during the high-temperature and high-pressure laminating process of the EC electrochromic component, and the thickness of the electrolyte layer is still difficult to keep consistent. SUMMARY

[0006] In order to solve the problem of low yield of the curved light-adjusting glass, the present application provides an EC electrochromic component, a curved light-adjusting component and a preparation method thereof.

[0007] In a first aspect, the present application provides an EC electrochromic component, which adopts the following technical solution:

[0008] An EC electrochromic component comprises an electrolyte layer, a highly consistent supporting component is provided in the electrolyte layer, and a transparent deformation layer is provided on one side of the electrolyte layer.

[0009] By adopting the above technical solution, the support component and the transparent deformation layer are combined to form an electrochromic component structure, which can significantly improve the yield and production rate of curved dimming glass. The principle is as follows:

[0010] The support component plays a supporting role in the electrolyte layer and regulates the thickness of the electrolyte layer. The thickness of the electrolyte layer is determined by the height of the support component. Due to the supporting role of the support component, the high temperature and high pressure during the assembly process have little impact on the electrolyte layer. The electrolyte layer is evenly stressed and the thickness of the electrolyte layer remains uniform throughout the assembly process, thereby improving the yield rate of curved dimming glass.

[0011] The thickness of the electrolyte layer is close to the thickness of the gap between the two substrate layers. The transparent deformable layer undergoes slight deformation during the lamination process to make up for the gap margin between the thickness of the electrolyte layer and the thickness of the gap between the substrate layers. The electrolyte layer with the added support component has high hardness, which makes up for the defects of wrinkles in the transparent deformable layer due to high temperature and high pressure during the lamination process, thereby improving the fit between the EC electrochromic component and the curved substrate layer. Macroscopically, it manifests as the curved dimming glass with uniform color, no water ripple defects, and good optical quality.

[0012] Preferably, the support member is a spacer or a grid plate. More preferably, the support member is a grid plate.

[0013] By adopting the above technical solution, the spacers are discrete hard objects, which can be hollow glass microbeads; and the grid plate has a continuous and stable grid structure, which can have excellent compressive resistance, further reducing the possibility of deformation of the electrolyte layer during the assembly process, and improving the stability of the EC electrochromic component during the assembly process.

[0014] Preferably, the space shape of the grid plate is any one of polygonal, circular, and scale-shaped.

[0015] By adopting the above technical solution, the spaces of the grid plate can be of any shape, such as polygonal, circular, scale-shaped, etc.

[0016] Preferably, the electrolyte in the electrolyte layer is filled in the spaces of the grid plate.

[0017] By adopting the above technical solution, EC electrochromic components can be directly cut. Even if a small amount of electrolyte leaks around the edge of the electrolyte layer, it will not affect the use of the curved dimming glass. There is no need to seal the edges specifically according to the size required by the customer's production, which simplifies the production process and further improves the yield of the curved dimming glass.

[0018] Optionally, the transparent deformable layer is subjected to biaxial stretching treatment.

[0019] Optionally, the material of the transparent deformation layer is one or more of PC, PE, PMMA, and PET.

[0020] Preferably, the material of the transparent deformation layer is PC.

[0021] By adopting the above technical solution, the refractive index of PC is better, and the degree of deformation under high temperature and high pressure is slight, but it can still meet the required control margin.

[0022] In a second aspect, the present application provides a curved dimming component, which adopts the following technical solution:

[0023] A curved dimming component is made of the aforementioned EC electrochromic component.

[0024] By adopting the above technical solution, the aforementioned electrochromic component has a high degree of adhesion to the curved substrate layer, the electrolyte layer has a uniform thickness, and there is no water ripple defect, which can make the curved dimming component have uniform color, good optical quality, and a high yield rate of the curved dimming component.

[0025] Preferably, the curved dimming component further includes a substrate layer, which is located on both sides of the EC electrochromic component, and the material of the substrate layer is PC-PMMA co-extruded sheet or glass.

[0026] By adopting the above technical solution, the PC-PMMA co-extruded sheet has excellent impact resistance, corrosion resistance and lightweight characteristics, which can provide long-term protection for the internal EC electrochromic components, thereby extending the service life of the curved dimming components.

[0027] In a third aspect, the present application provides a method for preparing a curved dimming component, which adopts the following technical solution.

[0028] A method for preparing a curved dimming component includes the following steps:

[0029] The transparent deformable layer is stretched to a target shape, and an ITO layer and an electrode layer are fixed in sequence on one side of the transparent deformable layer to obtain a pre-processing component 1;

[0030] The two substrate layers are deformed to a target shape, a film layer is placed on one side of one of the substrate layers, and the film layer is fixed to the transparent deformable layer of the pre-treatment component 1 by hot pressing to obtain a pre-treatment component 2;

[0031] An ITO layer and an electrode layer are sequentially fixed on one side of the other substrate layer to obtain a pre-processed component three;

[0032] Select one of the electrode layer of the pre-processing component 2 and the electrode layer of the pre-processing component 3 to be made into an ion storage layer, and the other electrode layer to be made into an electrochromic layer;

[0033] When the support component is a grid plate, a grid is printed on the electrode layer, an electrolyte is filled in the grid, and the electrode layers are arranged relative to each other, so that the pre-processing component 2 and the pre-processing component 3 are combined and cured to obtain a curved dimming component;

[0034] When the support component is selected as a spacer, the spacer is added to the electrolyte and mixed evenly, and then injected between the electrode layer of the pretreatment component 2 and the electrode layer of the pretreatment component 3, and then extruded, cured, and sealed to obtain a curved dimming component.

[0035] By adopting the above technical solution, the process sequence of first stretching the transparent deformable layer and the substrate layer and then sputtering the ITO circuit makes the ITO layer circuit complete and less likely to be damaged by external forces during the preparation process of the curved dimming component, thereby improving the yield rate of the curved dimming component.

[0036] Moreover, by laminating the electrolyte layer and utilizing the supporting function of the supporting parts of the electrolyte layer, the pretreatment component two and the pretreatment component three can be quickly laminated, and the slight deformation of the transparent deformation layer is used to ensure the thickness of the electrolyte layer is consistent. Compared with traditional lamination technology, the lamination method of the present application does not need to calibrate the gap difference between the curved substrate layers multiple times to ensure that the gap difference at each part of the substrate layer is close to consistent, which simplifies the lamination process and improves the production efficiency of the curved dimming components.

[0037] In summary, this application has at least the following features:

[0038] 1. The present application pre-sets a highly consistent support component in the electrolyte layer, so that the color-developing electrolyte layer has a consistent thickness on the curved glass and is not easily deformed during the curved glass preparation process; the transparent deformable layer is used in conjunction with the support component, and the transparent deformable layer can be slightly deformed, so that the EC electrochromic component and the substrate layer can be directly assembled, and the EC electrochromic component and the substrate layer can be completely adhered without multiple calibrations, thereby simplifying the preparation steps of the curved dimming glass.

[0039] 2. In this application, a grid-shaped support component is preferably used. On the one hand, it has good pressure resistance, further reducing the deformation of the electrolyte layer during the pressing process, and improving the stability of the EC electrochromic component during the assembly and pressing process; on the other hand, the grid-shaped support component can encapsulate the electrolyte in its spaces, so that the EC electrochromic component can be directly cut. Even if a small amount of electrolyte leaks from the edge of the electrolyte layer, it will not affect the use of the curved dimming glass. There is no need to seal the edges specifically according to the size required by the customer's production, which simplifies the production process and further improves the yield of the curved dimming glass.

[0047] Traditional curved dimming glass rarely uses EC electrochromic components as dimming elements. Because the curvature of the two substrate layers in curved dimming glass is difficult to achieve perfect uniformity, the gap difference between the two substrate layers is inconsistent. During the assembly process, the EC electrochromic components are thermally deformed, resulting in inconsistent thickness of the electrolyte layer. This results in inconsistent color depth in the curved dimming glass, making it difficult to meet optical quality standards. To improve the optical quality of curved dimming glass, the relative position of the two substrate layers must be repeatedly adjusted to achieve a nearly uniform gap before assembly can proceed. Consequently, the yield rate of curved dimming glass is low. This technical difficulty has hindered the development of EC electrochromic components.

[0048] Based on this discovery, the applicant conducted extensive research on curved dimming glass and found that providing a support component with moderate hardness within the electrolyte layer can ensure that the electrolyte layer remains consistent throughout the curved dimming glass manufacturing process. This support component is combined with a transparent deformable layer, and the electrolyte layer thickness approximates the gap thickness between the two substrate layers. The transparent deformable layer undergoes slight deformation during the assembly process, which is used to adjust the clearance margin between the support component height and the gap thickness between the substrate layers. This successfully solves the technical problem addressed by this application.

[0049] In addition, by changing the shape of the supporting component, a curved dimming glass with better optical quality can be obtained. This application is made based on the above discovery.

[0050] The following is combined with Figure 1-5 This application is described in further detail. Example

[0051] Example 1

[0052] This application discloses an EC electrochromic component. Figure 1 and Figure 2 The EC electrochromic component includes a transparent deformable layer 3, an ITO layer 4, an electrode layer, an electrolyte layer 1, an electrode layer, and an ITO layer 4, arranged in that order. A highly consistent support member 2 is provided within the electrolyte layer 1. One of the two electrode layers is formed into an ion storage layer 51, and the other into an electrochromic layer 52. The positions of the ion storage layer 51 and the electrochromic layer 52 can be interchanged. In this embodiment, the EC electrochromic component comprises a transparent deformable layer 3, an ITO layer 4, an ion storage layer 51, an electrolyte layer 1, an electrochromic layer 52, and an ITO layer 4, arranged in that order.

[0053] Reference Figure 1 and Figure 2 The height of the support member 2 determines the thickness of the electrolyte layer 1. The support member 2 can be continuous or discrete, and both types can be used to connect the ion storage layer 51 and the electrochromic layer 52. The electrolyte in the electrolyte layer 1 is filled in the gap formed by the support member 2, the ion storage layer 51, and the electrochromic layer 52, and the electrolyte filling height is consistent with the height of the support member 2. The electrolyte can be liquid or gel. In this embodiment, the electrolyte is liquid.

[0054] Reference Figure 2 In this embodiment, the support member 2 is a continuous grid plate, and the electrolyte is located in each space of the grid plate ( Figure 2 The shaded area is the electrolyte), so that the electrolyte layer 1 has a uniform color. Figure 1The grid plate is composed of two layers of grids, one of which is fixedly connected to the ion storage layer 51 by screen printing, and the other is fixedly connected to the electrochromic layer 52 by screen printing.

[0055] Reference Figure 2 The mesh spacing of one layer of mesh is larger than that of the other. This allows the resulting grid plate to form several closed spaces with the ion storage layer 51 and electrochromic layer 52, ensuring excellent sealing of the electrolyte within the electrolyte layer. Therefore, the EC electrochromic component can be directly cut to the target size. Even if a small amount of electrolyte leaks around the edge of the electrolyte layer 1, its use in the curved dimming component is not affected. Special edge sealing to the target size is not required, simplifying the production process.

[0056] The material of the grid plate can be a conductive material or an insulating material. In this embodiment, the grid plate is prepared using low-temperature conductive silver paste, which is sourced from Shanghai Kuang Yu Technology Co., Ltd. and has the brand name TC-H660.

[0057] Reference Figure 2 The spaces of the grid plate can be of any shape, including but not limited to polygonal, circular, and scale-shaped. In this embodiment, a parallelogram is selected, more specifically, a rectangle.

[0058] Reference Figure 1 In this embodiment, the material of the ion storage layer 51 is nickel oxide, and the material of the electrochromic layer 52 is tungsten oxide. The ion storage layer 51, the electrolyte layer 1 and the electrochromic layer 52 form a charge path, and the EC electrochromic component can switch between a transparent state and a foggy state.

[0059] Reference Figure 1 The material of the ITO layer 4 is indium tin oxide, which is fixed by sputtering to form a conductive path, serving as a switch for the EC electrochromic component to switch between the transparent state and the foggy state.

[0060] Reference Figure 1 The transparent deformable layer 3 is used in conjunction with the electrolyte layer 1 to simplify the production process of the curved dimming component. The transparent deformable layer 3 has a certain degree of deformability and can be biaxially stretched. It has moderate hardness and good optical transparency. Materials for the transparent deformable layer 3 include, but are not limited to, PC, PMMA, PE, and PET. In this embodiment, the transparent deformable layer 3 is made of PC.

[0061] Reference Figure 1The thickness of the electrolyte layer 1 is determined by the thickness of the supporting component 2, which is close to the gap difference between the substrate layers of the curved light modulation assembly. During the lamination process of the curved light modulation glass, the transparent deformation layer 3 is slightly deformed to compensate for the remaining gap between the substrate layers and the EC electrochromic assembly in the curved light modulation assembly. The supporting component 2 makes the electrolyte layer 1 have high hardness, which can compensate for the wrinkles of the transparent deformation layer 3 caused by high temperature and high pressure during the lamination process, thereby improving the adhesion of the EC electrochromic assembly and the curved substrate layer, and macroscopically showing that the curved light modulation assembly has uniform color and good optical quality.

[0062] Example 2

[0063] Example 2 is different from Example 1 in that the supporting component is different.

[0064] Reference Figure 3 In this embodiment, the supporting component 2 is a discrete gap sub, and the gap sub is a hollow glass bead. In this embodiment, the layers of the EC electrochromic assembly are arranged in the order of the transparent deformation layer 3, the ITO layer 4, the electrochromic layer 52, the electrolyte layer 1, the ion storage layer 51, and the ITO layer 4.

The material of the substrate layer 7 includes but is not limited to glass, PC-PMMA co-extruded sheet. In this application example, PC-PMMA co-extruded sheet is selected to make the substrate layer 6 because it has high strength, excellent impact resistance and high wear resistance.
