Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to a glass fiber adhesive tape. Background Technology

[0002] In many industrial and daily life sectors today, adhesive tape plays an indispensable role as a commonly used bonding and fixing material. With the continuous development of various industries and the increasing demands on material performance, traditional adhesive tapes are gradually becoming insufficient to meet diverse application needs. Therefore, developing new adhesive tapes with superior performance and multifunctional properties has become an important research direction in the field of materials science.

[0003] Fiberglass tape, with its inherent high strength and other properties, has found some application in industries such as electronic equipment manufacturing, automobile assembly, and building decoration. However, existing fiberglass tapes still have many limitations.

[0004] On the one hand, in terms of strength, traditional fiberglass tape relies solely on fiberglass for strength support. In some special application scenarios with extremely high strength requirements, such as temporary fixation of aerospace components subjected to high tensile strength and sealing and bonding of key parts of large engineering machinery, the strength it can provide may be slightly insufficient, and it cannot ensure that it can stably play a bonding and fixing role for a long time under complex working conditions.

[0005] On the other hand, in terms of functional diversity, traditional fiberglass tape has a relatively limited range of functions. For example, in scenarios where heat transfer may affect the bonding effect or the performance of the bonded objects, such as bonding near the heat dissipation area of ​​electronic devices or sealing and protecting equipment in high-temperature industrial environments, ordinary fiberglass tape lacks effective heat insulation measures. Heat can easily be transferred through the tape, which may lead to problems such as bonding failure, heat deformation of the bonded objects, or performance damage.

[0006] Furthermore, during use, the surface of adhesive tape inevitably suffers various forms of damage, such as scratches and abrasions. For traditional fiberglass tape, such damage not only affects its appearance but, more importantly, may reduce its bonding performance and overall lifespan. Moreover, most tapes currently lack the ability to self-repair damage, which often forces users to replace the tape with a new one after minor damage, increasing usage costs and wasting resources.

[0007] Therefore, a new type of glass fiber adhesive tape needs to be designed to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fiberglass tape that exhibits superior performance in terms of strength, heat insulation, self-healing, and appearance, thereby better meeting the diverse needs of different industries and application scenarios.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A fiberglass tape includes a tape body, which is composed of a strength layer, an adhesive layer, a heat insulation layer, an OPP film, and a repair layer. The strength layer is woven from a mixture of fiberglass and carbon fiber. The adhesive layer is located below the strength layer, the heat insulation layer is located above the strength layer, the OPP film is located above the heat insulation layer, and the repair layer is located above the OPP film.

[0011] Preferably, the strength layer and the heat insulation layer are adhered together by a first adhesive layer, the heat insulation layer and the OPP film are adhered together by a second adhesive layer, and the OPP film and the repair layer are adhered together by a third adhesive layer.

[0012] Preferably, the glass fiber is woven clockwise, the carbon fiber is woven counterclockwise, and the glass fiber and carbon fiber are interwoven.

[0013] Preferably, the heat insulation layer is made of polyimide.

[0014] Preferably, the repair layer is made of thermoplastic polyurethane, and the thermoplastic polyurethane is transparent.

[0015] Preferably, the OPP film is printed with a pattern.

[0016] Compared with existing technologies, the advantages of this device are:

[0017] 1. Compared with existing technologies, the strength layer is formed by cross-weaving glass fiber and carbon fiber, which further enhances the strength of the glass fiber tape, enabling the tape to play a stable bonding and fixing role for a long time under complex working conditions.

[0018] 2. Compared with existing technologies, the addition of heat insulation and repair layers effectively insulates the tape during use, preventing heat from being transferred through the tape and causing the adhesive on the adhesive layer to fail. At the same time, the repair layer allows the tape to automatically repair itself after minor damage, reducing usage costs and resource waste.

[0019] 3. Compared with existing technologies, the OPP film allows for the printing of sophisticated and complex patterns, enhancing the overall aesthetics of the tape. Furthermore, the OPP film, located beneath the repair layer, protects the OPP film and prevents damage to the patterns. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-3 A fiberglass tape includes a tape body 1, which is composed of a strength layer 2, an adhesive layer 3, a heat insulation layer 5, an OPP film 7, and a repair layer 9. The strength layer 2 is woven from a mixture of fiberglass and carbon fiber. The adhesive layer 3 is located below the strength layer 2, the heat insulation layer 5 is located above the strength layer 2, the OPP film 7 is located above the heat insulation layer 5, and the repair layer 9 is located above the OPP film 7. The strength layer 2 and the heat insulation layer 5 are adhered together by a first adhesive layer 4, the heat insulation layer 5 and the OPP film 7 are adhered together by a second adhesive layer 6, and the OPP film 7 and the repair layer 9 are adhered together by a third adhesive layer 8.

[0026] The glass fiber is woven clockwise, and the carbon fiber is woven counterclockwise. The glass fiber and carbon fiber are interwoven, which further increases the overall strength of the tape.

[0027] The heat insulation layer 5 is made of polyimide, which has excellent high-temperature resistance and can operate at temperatures above 200°C for extended periods. Some high-performance polyimides can even operate at around 400°C. The repair layer 9 is made of thermoplastic polyurethane, which is transparent. Thermoplastic polyurethane consists of hard and soft segments. The urethane segments in the hard segments can form intermolecular hydrogen bonds, providing tensile strength, wear resistance, and heat resistance. The soft segments provide elasticity, and the intermolecular hydrogen bonds can dissociate when the temperature is increased and reform intermolecular hydrogen bonds and physical cross-links when the temperature is decreased, thus achieving self-repair. The transparent nature of the thermoplastic polyurethane allows it to display the pattern on the OPP film 7 while also protecting the OPP film 7, which is printed with patterns.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
