Description

Technical Field

[0001] The utility model relates to a cover plate assembly, more specifically, to a novel silk-screen coating cover plate assembly. Background Art

[0002] With technological advancements and rising demands for product performance, glass cover panels, as a crucial component of display electronics, are becoming a hot topic in terms of performance optimization and multifunctionality. Traditional glass cover panels suffer from deficiencies in chemical stability, mechanical properties, and optical performance, making them difficult to meet the high-performance demands of modern electronic products. In particular, they often fall short of HNA customers' requirements for waterproofing and heat resistance. Therefore, developing a novel multilayer coating structure that combines the advantages of different chemical substances to improve the overall performance of glass cover panels holds significant practical significance and holds broad market prospects.

[0003] Chinese utility model patent document CN205563516U discloses an electronic touch screen, which is a touch screen for a mobile phone or tablet computer, including a glass cover plate, wherein the glass cover plate includes a glass cover plate substrate, an optical coating layer covering the inner surface of the glass cover plate substrate, and an ink silk-screen layer covering the inner surface of the optical coating layer, wherein the optical coating layer and the ink silk-screen layer are located in the screen edge area outside the screen visible area of ​​the glass cover plate. The optical coating layer includes a silicon dioxide layer covering the inner surface of the glass cover plate substrate and titanium dioxide stacked on the silicon dioxide layer. Obviously, in the standby state of this patent, the screen edge area of ​​the glass cover plate on the front of the electronic touch screen is consistent with the color of the screen visible area, so that the front of the device obtains a one-color visual effect. However, this structure cannot solve the stability problem of the existing cover plate. Utility Model Content

The novel silk-screen coated cover plate assembly comprises a glass substrate, an isolation layer disposed on the upper surface of the glass substrate, a wear-resistant layer disposed on the upper surface of the isolation layer, and a waterproof layer disposed on the upper surface of the wear-resistant layer. The isolation layer is an yttrium oxide film, the wear-resistant layer is a silicon dioxide film, and the waterproof layer is an acrylic resin film. Both the isolation layer and the wear-resistant layer are physically deposited films, and the waterproof layer is a silk-screen film. This novel silk-screen coated cover plate assembly utilizes a multi-layer coating structure designed by coating the front surface of the glass cover plate with yttrium oxide and silicon dioxide, and then silk-screening an acrylic resin layer on the outermost layer as a protective and waterproof layer. First, a barrier layer composed of yttrium oxide is formed on the surface of the glass cover plate through physical or chemical methods. This layer effectively prevents moisture, oxygen, and other chemicals from corroding the internal materials, thereby improving the chemical stability of the cover plate. Next, a silicon dioxide layer is deposited on the barrier layer. This layer has high hardness and wear resistance, enhancing the mechanical properties and improving the optical performance of the cover plate. Finally, a layer of acrylic resin is covered on the outermost layer through the silk-screen printing process as a protective and waterproof layer, which can effectively prevent the external environment from damaging the internal coating layer and improve the weather resistance, heat resistance and UV resistance of the cover.

[0028] As described in the background, with the advancement of technology and increasing demand for product performance, glass cover plates, as a key component of display electronics, are currently undergoing significant research, with performance optimization and multifunctionality becoming a hot topic. Traditional glass cover plates suffer from deficiencies in chemical stability, mechanical properties, and optical performance, making them difficult to meet the high-performance requirements of modern electronic products.

[0030] Through the above-mentioned structural design, the new silk-screen coated cover assembly uses chemical substances yttrium oxide and silicon dioxide to coat the front of the glass cover, and covers the outermost layer with acrylic resin by silk-screen printing as a multi-layer structure coating layer design as a protective and waterproof layer. First, a barrier layer composed of yttrium oxide is formed on the surface of the glass cover by physical or chemical methods.

Then, a layer of silicon dioxide is deposited on the barrier layer. This layer has high hardness and wear resistance, can enhance the mechanical properties of the cover, and improve its optical properties. Finally, a layer of acrylic resin is covered on the outermost layer through the silk-screen process as a protective and waterproof layer, which can effectively prevent the external environment from damaging the internal coating layer and improve the weather resistance, heat resistance and UV resistance of the cover.

[0037] In addition, the isolation layer 2 and the wear-resistant layer 3 are both physically deposited films. The waterproof layer 4 is a silk-screen film.

[0038] The working mode of this embodiment is described below.

[0039] This new silk-screen coated cover assembly utilizes yttrium oxide and silicon dioxide to coat the front of the glass cover. The outermost layer is then silk-screened with acrylic resin, creating a multi-layer coating structure that acts as a protective and waterproof layer. First, a barrier layer composed of yttrium oxide is formed on the surface of the glass cover through physical or chemical methods. This layer effectively prevents moisture, oxygen, and other chemicals from corroding the internal materials, thereby improving the cover's chemical stability.

[0045] The yttrium oxide film on the glass substrate 1 can prevent moisture, oxygen, and other chemicals from corroding the internal materials, thereby improving the chemical stability of the cover. The silicon dioxide film can enhance the mechanical properties of the cover due to its high hardness and wear resistance. At the same time, silicon dioxide film is also a common optical material, which helps to improve the transmittance of the cover. The acrylic resin film can protect the internal coating layer from the influence of the external environment due to its good weather resistance and UV resistance. At the same time, its waterproof performance can also effectively prevent moisture from corroding the internal materials. Since the sealing sleeve 5 surrounds the entire cover, it has excellent waterproof performance.
