Description

Technical Field

[0001] The utility model relates to the technical field of polycarbonate films, in particular to a PC film panel with anti-light transmission properties for electronic equipment. Background Art

[0002] With the rapid development of the electronics industry, the continuous advancement of technological innovation and the continuous improvement of user needs, electronic equipment must not only consider stable functions and reliable performance, but also pay attention to user experience and visual aesthetics.

[0003] As an important component of electronic device display and control, PC film panel carries the basic function display of equipment, visual information transmission, guides humanized operation, is durable, protects the surface, and conveys visual beauty.

[0004] PC film is a decorative panel based on polycarbonate (PC) and completed with text, logo, pattern, color and its protection through subsequent design, processing, production and other process. Since the molecular structure of polycarbonate (PC) material contains flexible carbonate base and rigid benzene ring, it has many special properties that other engineering plastics do not have, such as good transparency, wear resistance, corrosion resistance, dimensional stability, easy processing and other unique advantages, so it is widely used in electronic equipment, which plays a good role in improving the quality of electronic equipment.

[0005] However, the existing electronic equipment display and control panel generally adopts the structure of spraying + lettering, spraying + silk screen or PC film. Among them, PC film is to paste the PC film panel on the display and control interface of the electronic equipment according to the structural design area. When the equipment is working normally, the brightness of the display and control area lights, electronic screens and other display functions will cause light leakage, peripheral halo, film light transmission and other problems on the PC film panel, resulting in poor display effect when the electronic equipment is in working state, poor user visual experience, and product quality not meeting expectations.

[0006] In view of this, this application is hereby filed. Utility Model Content

[0007] The technical problem to be solved by the utility model is that the existing PC film panels do not take into account the negative impact caused by the light transmittance of the film. The purpose is to provide a PC film panel with anti-light transmittance properties for electronic equipment. By adding multiple adhesion layers and white ink layers to the existing layer structure, the adhesion layer can play a role of connecting the upper and lower layers, protecting the lower layer and increasing the adhesion of the upper layer. The white ink layer can protect the basic background color and prevent the bottom from being seen through and the basic background color from becoming darker due to screen printing of black directly on the basic background color, thereby reducing the light transmittance of the panel and solving the problems of light transmittance, light leakage, halo overflow, adhesion, etc.

[0008] The utility model is realized by the following technical solutions:

[0009] A PC film panel with anti-light transmission properties for electronic equipment, comprising a substrate layer, a logo layer, a base color layer, an ink layer and a glue layer, characterized in that:

[0010] A first adhesion layer is provided between the logo layer and the base color layer;

[0011] A second adhesion layer, a white ink layer and a third adhesion layer are sequentially arranged between the basic base color layer and the ink layer.

[0012] The utility model adds multiple adhesion layers and white ink layers to the existing layer structure. The adhesion layer can play a connecting role between the upper and lower layers, protecting the lower layer and increasing the adhesion of the upper layer. The white ink layer can protect the basic background color and prevent the bottom from being seen through and the basic background color becoming darker due to screen printing of black directly on the basic background color, thereby reducing the light transmittance of the panel and solving the problems of light transmittance, light leakage, halo overflow, adhesion, etc.

[0013] In a specific embodiment, the substrate layer is a polycarbonate layer. As the basic support layer of the PC film panel, the PC substrate layer can provide a stable structural foundation to ensure the overall stability and reliability of the panel. The PC material has good mechanical strength, impact resistance and scratch resistance, and can effectively protect the internal components of the panel from external physical damage.

[0014] In a specific embodiment, the thickness of the substrate layer is 0.15 to 1.0 mm. The specific thickness can be determined according to the application requirements. Thinner PC substrates are used for panels that require lightness and flexibility, while thicker substrates are used for applications that require higher strength and durability.

[0015] In a specific embodiment, the marking layer is an ink layer of text, logos, patterns, etc., which can provide clear and unambiguous identification information for the PC film panel, such as product model, button function, brand logo, etc., to facilitate user identification and use. In addition, the ink has certain wear resistance and protective properties, which can ensure that the text / logo / graphics on the back are not easily worn or damaged.

[0016] The thickness of the ink in the marking layer is determined according to specific needs. Generally speaking, the thickness of the ink in the text / logo / graphic layer is between a few microns and tens of microns.

[0017] In a specific embodiment, the main function of the base color layer is to provide a uniform and consistent base color for the back of the PC film panel, which helps to improve the overall appearance and make the panel more beautiful. At the same time, the base color layer can cover the original color or defects on the back of the panel and provide a layer of protection to prevent color fading or damage caused by external environmental factors (such as ultraviolet rays, humidity, etc.). Generally speaking, the thickness of the base color layer should be moderate, which can ensure good hiding power while avoiding color distortion or unclear printing caused by excessive thickness.

[0018] In a specific embodiment, the first adhesion layer, the second adhesion layer and the third adhesion layer all use a penetrant that can cross-link with the substrate layer.

[0019] In a specific embodiment, the permeabilizing agent is DMSO.

[0020] The utility model can significantly improve the adhesion between the layers of the PC film panel by setting the adhesion layer, ensure a firm fit and prevent it from falling off; at the same time, by enhancing the adhesion, the adhesion layer can improve the stability of the PC film panel during use, reduce displacement or falling off caused by external factors (such as vibration, temperature change, etc.), thereby ensuring its stability and reliability.

[0021] In a specific embodiment, the thickness of the first adhesion layer is 5-10 μm, the thickness of the second adhesion layer is 5-10 μm, and the thickness of the third adhesion layer is 5-10 μm. Adhesion layers of moderate thickness can provide sufficient adhesion while maintaining the flexibility and transparency of the PC film panel.

[0022] In a specific embodiment, for the PC film panel that needs to display information on the back, the white ink layer can significantly improve the contrast with the background or other colors, making the information more eye-catching. In addition, white ink usually has a strong hiding power, which can cover the background color or defects on the back of the PC film panel, improve the overall quality and appearance of the PC film panel, and make the product appearance neater. The thickness of the white ink layer is 20 to 25 μm to ensure good hiding power and clarity.

[0023] In a specific embodiment, the ink layer is a black ink layer with a thickness of 20 to 25 μm. A black ink layer is provided on the outer back side to ensure the consistency of the back side of the panel and make the overall appearance more uniform. At the same time, it can block unnecessary information or defects on the back side of the panel and provide certain protection against erosion by chemicals or the external environment.

[0024] In a specific embodiment, the adhesive layer is a 3M adhesive layer. The 3M adhesive has extremely strong viscosity, which can ensure that the PC film panel is tightly adhered to the required surface and is not easy to fall off or shift. This simplifies the installation process of the PC film panel and reduces the use of additional fixings or tools. Through the adhesion of the 3M adhesive layer, the PC film panel can obtain higher stability in application and reduce displacement or damage caused by vibration or impact; at the same time, it has waterproof and anti-pollution properties, which can protect the PC film panel from the influence of the external environment.

[0025] In a specific embodiment, the thickness of the adhesive layer is 0.05-0.25 mm.

[0026] The materials such as penetrants and inks involved in the utility model are all existing preparations. The utility model only involves the selection of adhesion layer materials, but does not involve the improvement of the formula of the materials themselves.

[0027] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0028] The embodiment of the utility model provides a PC film panel with anti-light transmission properties for electronic devices. By adding multiple adhesion layers and white ink layers in the existing layer structure, the adhesion layer can play a role of connecting the upper and lower layers, protecting the lower layer and increasing the adhesion of the upper layer. The white ink layer can protect the basic background color and prevent the bottom from being seen through and the basic background color from becoming darker due to screen printing of black directly on the basic background color, thereby reducing the light transmittance of the panel and solving the problems of light transmittance, light leakage, halo overflow, adhesion, etc. BRIEF DESCRIPTION OF THE DRAWINGS
