Description

A type of antistatic tape with good light-blocking properties Technical Field

[0001] This utility model relates to the field of tape technology, and in particular to an antistatic tape with good light-blocking performance. Background Technology

[0002] The tape has the functions of light blocking and anti-static properties, mainly to meet the needs of specific application scenarios.

[0003] Display screens and backlight modules for electronic products: Light-blocking tape can be used in the display screens and backlight modules of electronic products such as laptops, tablets, and smartphones to block light and fix components such as LED light strips.

[0004] If the tape is not anti-static, it will stick to the object due to static electricity after being stretched and cut. For example, if the tape is cut into long pieces by hand, it will stick to the clothes. Sometimes the adhesive side of the tape will stick together and needs to be torn apart, which is very inconvenient to use.

[0005] Therefore, this application proposes an antistatic tape with good light-blocking performance. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides an antistatic tape with good light-shielding properties.

[0007] An embodiment of this utility model provides an antistatic tape with good light-shielding performance, comprising:

[0008] Take-up drum;

[0009] The tape is wound onto a take-up drum; the tape includes a substrate, and a first light-shielding layer and a second light-shielding layer are respectively provided on both sides of the substrate, the second light-shielding layer is provided with an adhesive surface, and the first light-shielding layer is provided with an antistatic layer.

[0010] Furthermore, the substrate is made of polyvinyl chloride film.

[0011] Furthermore, both the first light-shielding layer and the second light-shielding layer are frosted surfaces on the substrate.

[0012] Furthermore, the antistatic layer is made of an antistatic agent coated on the first light-shielding layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention increases the light-blocking properties of the tape by frosting the substrate. The process is simple and the light-blocking effect is significant. It also increases the contact area with the antistatic layer and the adhesive surface, making the antistatic layer and the adhesive surface adhere more stably to the substrate, thereby ensuring that the tape maintains excellent performance and quality during long-term use.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] As shown in Figures 1-3, this utility model embodiment proposes an antistatic tape with good light-shielding performance, comprising:

[0021] Adhesive tape 2 is tightly wound onto the take-up spool 1. This tape 2 is designed to incorporate a variety of high-performance characteristics to meet a wide range of application needs. At the heart of tape 2 is the substrate 21, which is made of high-quality polyvinyl chloride (PVC) film, a material highly regarded for its excellent chemical stability. PVC film effectively resists the erosion of various acids, alkalis, salts, and other chemicals, while also exhibiting good stability against oxidizing agents, reducing agents, and most organic solvents.

[0022] In terms of weather resistance, PVC film performs excellently, maintaining stable performance under various climatic conditions. Whether in scorching heat or freezing cold, PVC film retains its original physical and chemical properties, ensuring that tape 2 functions properly in all environments.

[0023] Furthermore, polyvinyl chloride film is also an excellent insulating material, widely used in electronics, electrical appliances, and other fields. Its superior insulation properties provide a solid guarantee for the application of tape 2 in the electrical field.

[0024] Flame retardancy is also a major highlight of PVC film. It is not easily combustible and produces less smoke and toxic gases when burning, which greatly improves the safety of tape 2.

[0025] In the structural design of tape 2, a first light-shielding layer 23 and a second light-shielding layer 24 are respectively provided on both sides of the substrate 21. Both light-shielding layers are frosted to reduce direct light reflection by forming diffuse reflection, thereby improving the light-shielding effect. This process is simple and has a significant light-shielding effect, providing reliable performance assurance for tape 2 in applications requiring light shielding.

[0026] Of particular note is the adhesive surface 25 on the second light-shielding layer 24, which facilitates the adhesion of the tape 2. The first light-shielding layer 23 has an antistatic layer 22, which is made of an antistatic agent coated on the first light-shielding layer 23. The choice of antistatic agent is crucial; aliphatic amine salt antistatic agents are favored due to their excellent performance. These antistatic agents include stearamide, propyl dimethyl hydroxyethyl nitrate, etc., and are mainly used for antistatic treatment of polyester, polyvinyl chloride, and polyethylene films and products.

[0027] During the manufacturing process, the antistatic agent is first prepared into a solution using water or ethanol, and then adhered to the surface of the substrate 21 by methods such as coating, spraying, or dipping. After drying at room temperature or in hot air, the antistatic agent forms an antistatic coating on the surface of the substrate 21. This coating not only effectively prevents the generation and accumulation of static electricity, but also bonds tightly with the first light-shielding layer 23, improving the overall performance of the tape 2.

[0028] Since both the first light-shielding layer 23 and the second light-shielding layer 24 have a frosted surface, they can increase the contact area with the antistatic layer 22 and the adhesive surface 25. This allows the antistatic layer 22 and the adhesive surface 25 to adhere more stably to the substrate 21, thereby ensuring that the tape 2 maintains excellent performance and quality during long-term use.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
