Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically a high-adhesion waterproof fiberglass tape. Background Technology

[0002] High-adhesion waterproof fiberglass tape is a type of tape made with fiberglass as the base material and coated with a high-performance adhesive. It combines the high strength of fiberglass with the high adhesion of the adhesive, forming a strong and reliable bonding material. It is widely used in industries such as construction, automotive, and electronics. Its high adhesion, waterproof properties, weather resistance, and flexibility make it an ideal choice for various applications requiring high-strength bonding and waterproofing. While existing high-adhesion waterproof fiberglass tapes are widely used in multiple fields as a high-performance tape, some shortcomings have also been revealed in practical use. In some cases, the adhesion performance of high-adhesion waterproof fiberglass tapes may not be stable enough, leading to delamination during use. This may be due to insufficient adhesion between the adhesive and the substrate. Over time, the adhesive in the tape may gradually age and lose its original adhesive properties, leading to delamination. This aging phenomenon is more pronounced, especially in harsh environments such as high temperature, high humidity, or ultraviolet radiation. Furthermore, due to the lack of specialized tools, users often need to manually cut the tape, which is not only time-consuming and laborious but also makes it difficult to guarantee the length and accuracy of the cut. This is especially true in situations requiring precise dimensions, where the drawbacks of this cutting method are more obvious. If the operation is not done properly when manually cutting the tape, it may cause finger injuries or the tape to cut other items. In addition, the edges of the cut tape may be uneven, affecting the appearance and usability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-adhesion waterproof fiberglass tape. The cutting component allows for easy cutting of the tape while inserting a knife into the tape support sleeve for easy retrieval and to prevent loss. The adhesive component ensures that the adhesive layer adheres firmly to the tape and maintains stable performance even in environments with large temperature differences.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] A high-adhesion waterproof fiberglass tape includes: a tape loop with tape on its outer side; a cutting assembly disposed on the inner side of the tape loop, the cutting assembly including a knife, a connecting block, and a limiting block; and an adhesive assembly disposed on the outer side of the tape loop, the adhesive assembly including an anti-abrasion protective layer, a high-molecular-weight polyethylene layer, a first adhesive layer, a fiberglass material layer, a roughening layer, and a second adhesive layer.

[0006] Preferably, multiple support frames are fixedly installed inside the tape sleeve, and a tape support sleeve is fixedly connected to one end of each support frame. Multiple limiting grooves are opened inside the tape support sleeve.

[0007] Preferably, the tape support sleeve has a small knife inside, the small knife is divided into a blade tip and a blade shaft, a connecting block is fixedly installed on one side of the small knife, and multiple limiting blocks are provided on the outside of the blade shaft. Both ends of the limiting blocks are provided with arc-shaped surfaces, and the limiting blocks are made of plastic.

[0008] Preferably, a high molecular weight polyethylene layer is adhered to the bottom of the wear-resistant protective layer, and a first adhesive layer is adhered to the bottom of the high molecular weight polyethylene layer, wherein the first adhesive layer is made of resin-based pressure-sensitive adhesive.

[0009] Preferably, a glass fiber material layer is adhered to the bottom of the first adhesive layer, and a rough layer is provided at the bottom of the glass fiber material layer, the outer surface of which is composed of multiple concave and convex triangular blocks.

[0010] Preferably, a second adhesive layer is adhered to the bottom of the roughened layer, and the second adhesive layer is made of resin-based pressure-sensitive adhesive.

[0011] The beneficial effects of this utility model are:

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5 As shown, a high-adhesion waterproof fiberglass tape includes:

[0023] The tape loop 1 has tape on its outer side and a cutting component on its inner side, which includes a knife 2, a connecting block 201, and a limiting block 202. The adhesive component is located on the outer side of the tape loop 1 and includes an anti-wear protective layer 3, a high molecular weight polyethylene layer 4, a first adhesive layer 5, a glass fiber material layer 6, a roughening layer 7, and a second adhesive layer 8.

[0024] The tape sleeve 1 has multiple support frames 101 fixedly installed inside. One end of the support frame 101 is fixedly connected to the tape support sleeve 102. The tape support sleeve 102 has multiple limiting grooves 103 inside. The tape support sleeve 102 has a small knife 2 inside. The small knife 2 is divided into a knife tip and a knife shaft. A connecting block 201 is fixedly installed on one side of the small knife 2. Multiple limiting blocks 202 are provided on the outside of the knife shaft. Both ends of the limiting blocks 202 are provided with arc-shaped surfaces. The limiting blocks 202 are made of plastic.

[0025] When in use, the connecting block 201 is pulled out. The arc-shaped surface of the limiting block 202 causes the limiting block 202 to be misaligned with the limiting groove 103. Since the limiting block 202 is made of plastic, it is deformed by compression when the connecting block 201 is pulled out. After being pulled out, the limiting block 202 will return to its original shape. After pulling out the knife 2, it can be used to cut the tape to the desired length. After use, the knife 2 is aligned with the inside of the tape support sleeve 102. When the connecting block 201 is pushed, the limiting block 202 is squeezed and deformed, and the knife 2 can be inserted into the support sleeve 102, so that the limiting block 202 is inserted into the limiting groove 103, thereby limiting the knife 2. When the limiting block 202 enters the limiting groove 103, the limiting block 202 returns to its original shape because the squeezing force disappears. Therefore, the knife 2 can be fixed in the tape support sleeve 102, making it convenient to take out when using the knife 2, without having to find a new tool to cut the tape.

[0026] Among them, a high molecular weight polyethylene layer 4 is adhered to the bottom of the anti-wear protective layer 3, a first adhesive layer 5 is adhered to the bottom of the high molecular weight polyethylene layer 4, the first adhesive layer is made of resin-type pressure-sensitive adhesive, a glass fiber material layer 6 is adhered to the bottom of the first adhesive layer 5, a rough layer 7 is provided at the bottom of the glass fiber material layer 6, the outer surface of the rough layer 7 is composed of multiple concave and convex triangular blocks, and a second adhesive layer 8 is adhered to the bottom of the rough layer 7, the second adhesive layer 8 is made of resin-type pressure-sensitive adhesive.

[0027] The abrasion-resistant protective layer 3 in the tape enhances its abrasion resistance, ensuring it maintains good adhesion and appearance even after prolonged use, and protecting the tape substrate. The high-molecular-weight polyethylene layer 4, due to its unique chemical structure and physical properties, effectively blocks moisture penetration, thus preventing damage to the first adhesive layer 5 and the second adhesive layer 8, providing excellent waterproofing. Furthermore, the strong adhesion between the high-molecular-weight polyethylene layer 4 and the first adhesive layer 5 ensures the tape will not easily detach. The glass fiber material layer 6 is a high-strength material that improves the tape's tensile and shear strength, ensuring its long-term durability. The glass fiber material layer 6 maintains stable performance during use, and its high temperature resistance prevents heat transfer to the tape and dissolution of the adhesive layer when the temperature rises. The concave and convex triangular blocks on the outer surface of the rough layer 7 increase the contact area between the second adhesive layer 8 and the rough layer 7, thereby increasing the adhesion of the second adhesive layer 8 and increasing the adhesion of the pressure-sensitive adhesive. The pressure-sensitive adhesive can better adhere to the tape, enhancing the practicality of the tape. The first adhesive layer 5 and the second adhesive layer 8 are made of resin-based pressure-sensitive adhesive, which has excellent weather resistance and heat resistance, effectively insulating heat and preventing the adhesive layer from peeling off.

[0028] Working principle:

[0029] When in use, the connecting block 201 is pulled out. The arc-shaped surface of the limiting block 202 causes the limiting block 202 to be misaligned with the limiting groove 103. Since the limiting block 202 is made of plastic, it is squeezed and deformed when the connecting block 201 is pulled out. After being pulled out, the limiting block 202 will return to its original shape. After pulling out the knife 2, it can be used to cut the tape to the desired length. After use, the knife 2 is aligned with the inside of the tape support sleeve 102, and the connecting block 201 is pushed. The limiting block 202 is squeezed and deformed. The blade 2 can be inserted into the support sleeve 102, causing the limiting block 202 to engage in the limiting groove 103. This limits the blade 2 within the limiting groove 103. As the pressure disappears, the limiting block 202 returns to its original position, thus securing the blade 2 within the tape support sleeve 102. This makes the blade easy to remove without needing to find a new tool to cut the tape. The abrasion-resistant protective layer 3 in the tape enhances its abrasion resistance, ensuring that the tape maintains good adhesion and appearance even after prolonged use. The protective tape substrate, with its high-molecular-weight polyethylene layer 4, effectively blocks moisture penetration due to its unique chemical structure and physical properties, thus preventing damage to the first adhesive layer 5 and the second adhesive layer 8. It possesses excellent waterproofing capabilities, and the strong adhesion between the high-molecular-weight polyethylene layer 4 and the first adhesive layer 5 ensures the tape will not easily detach. The glass fiber material layer 6, a high-strength material, improves the tape's tensile and shear strength, ensuring stable performance over long-term use. Simultaneously, the glass fiber material layer 6 is heat-resistant, preventing heat transfer to the tape and dissolution of the adhesive layer when temperatures rise. The concave-convex triangular blocks on the outer surface of the roughened layer 7 increase the contact area between the second adhesive layer 8 and the roughened layer 7, increasing the adhesion of the second adhesive layer 8 and thus enhancing the adhesion of the pressure-sensitive adhesive. This allows the pressure-sensitive adhesive to better adhere to the tape, improving its practicality. The first adhesive layer 5 and the second adhesive layer 8 are coated with resin-based pressure-sensitive adhesive, which has excellent weather resistance and heat resistance, effectively isolating heat and preventing the adhesive layer from peeling off.
