Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive tape technology, specifically to a high-temperature adhesive tape made of acrylic material that is resistant to high temperatures and electrolytes. Background Technology
[0002] Adhesive tape is a household product. Based on its function, it can be divided into: high-temperature tape, double-sided tape, insulating tape, specialty tape, pressure-sensitive tape, and die-cut tape. Different functions suit different industry needs.
[0003] In 1928, Richard Drew invented duct tape in St. Paul, Minnesota, USA. Duct tape has an adhesive coating on its surface to allow it to stick to objects. The earliest adhesives came from animals and plants; in the 19th century, rubber was the main component of adhesives; while modern adhesives widely use various polymers. However, existing high-temperature acrylic tapes lack corrosion resistance in actual use, which can lead to damage due to electrolyte corrosion. Therefore, we propose a high-temperature acrylic tape that is resistant to both high temperature and electrolyte. Utility Model Content
[0004] The purpose of this invention is to provide a high-temperature resistant acrylic tape that is resistant to high temperatures and electrolytes, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant acrylic tape resistant to high temperatures and electrolytes, comprising a winding frame with a through hole at the middle end, and a high-temperature tape body wound around the surface of the winding frame. The high-temperature tape body comprises a protective film, a heat insulation layer, and an adhesive layer. The protective film comprises a first film layer, a second film layer, and a third film layer. The bottom of the first film layer is connected to the top of the second film layer, and the bottom of the second film layer is connected to the top of the third film layer. The heat insulation layer comprises a first isolation layer, a second isolation layer, and a third isolation layer. The bottom of the first isolation layer is connected to the top of the second isolation layer, and the bottom of the second isolation layer is connected to the bottom of the third isolation layer.
[0006] Preferably, the first and second film layers are made of polyvinylidene fluoride film layers, and the third film layer is made of polytetrafluoroethylene film layer.
[0007] Preferably, the first and second isolation layers are made of glass fiber, and the third isolation layer is made of ceramic fiber.
[0008] Preferably, the thickness of the first and second isolation layers is 0.11mm-0.13mm, and the thickness of the third isolation layer is 0.12mm-0.14mm.
[0009] Preferably, the thickness of the first and second thin film layers is 0.11 mm to 0.15 mm, and the thickness of the third thin film layer is 0.14 mm to 0.16 mm.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes a protective film where the first and second film layers are polyvinylidene fluoride (PVDF) film layers, which possess excellent heat resistance; and a third film layer is a polytetrafluoroethylene (PTFE) film layer, PTFE being known as the "king of plastics" due to its extremely high heat resistance and chemical stability. The protective film further enhances the tape's high-temperature resistance while also protecting the internal structure. The heat insulation layer consists of a first, second, and third insulating layer. The first and second insulating layers are made of glass fiber, which possesses excellent heat insulation and high-temperature resistance, effectively blocking heat transfer. The third insulating layer is made of ceramic fiber, which also exhibits excellent high-temperature resistance and chemical stability at high temperatures. The synergistic effect of these three layers significantly improves the overall high-temperature resistance of the high-temperature tape, maintaining its performance stability and preventing deformation or damage under high-temperature conditions.
[0011] 2. This utility model utilizes a high-temperature adhesive tape body composed of a protective film, a heat insulation layer, and an adhesive layer. Each layer is tightly bonded and has a clearly defined function. The protective film provides protection and auxiliary high-temperature resistance and chemical corrosion resistance on the outer layer; the heat insulation layer plays a crucial role in heat insulation in the middle; and the adhesive layer ensures the tape can be firmly adhered to the desired location. Both the protective film and the heat insulation layer are composed of multiple layers. Through reasonable material selection and thickness settings—for example, the first and second isolation layers are 0.11mm-0.13mm thick, and the third isolation layer is 0.12mm-0.14mm thick; the first and second thin film layers are 0.11mm-0.15mm thick, and the third thin film layer is 0.14mm-0.16mm thick—the overall structure of the tape is stable and its performance is reliable.

The bottom of the first isolation layer 321 is connected to the top of the second isolation layer 322, and the bottom of the second isolation layer 322 is connected to the bottom of the third isolation layer 323. In practical use, the first and second film layers 311 and 312 of the protective film 31 are polyvinylidene fluoride (PVDF) film layers, which have good heat resistance; the third film layer 313 is a polytetrafluoroethylene (PTFE) film layer, which is known as the "king of plastics" and has extremely high heat resistance and chemical stability. The protective film further enhances the high-temperature resistance of the tape and also protects the internal structure. The heat insulation layer 32 consists of a first isolation layer 321, a second isolation layer 322, and a third isolation layer 323. The first and second isolation layers are made of glass fiber, which has good heat insulation and high-temperature resistance, effectively blocking heat transfer.

Example
[0017] Please see Figure 1 and Figure 2 The following technical solution is provided, specifically disclosing that: the first thin film layer 311 and the second thin film layer 312 are made of polyvinylidene fluoride thin film layer, the third thin film layer 313 is made of polytetrafluoroethylene thin film layer, the first isolation layer 321 and the second isolation layer 322 are made of glass fiber layer, the third isolation layer 323 is made of ceramic fiber layer, the thickness of the first isolation layer 321 and the second isolation layer 322 is 0.11mm-0.13mm, the thickness of the third isolation layer 323 is 0.12mm-0.14mm, the thickness of the first thin film layer 311 and the second thin film layer 312 is 0.11mm-0.15mm, and the thickness of the third thin film layer 313 is 0.14mm-0.16mm; In practical use, the high-temperature tape body 3 is composed of a protective film, a heat insulation layer, and an adhesive layer 33. Each layer is tightly bonded and has a clear function. The protective film provides protection and auxiliary high-temperature resistance and chemical corrosion resistance on the outer layer; the heat insulation layer plays a crucial role in heat insulation in the middle; and the adhesive layer ensures that the tape can be firmly adhered to the required location. Both the protective film and the heat insulation layer are composed of multiple layers. Through reasonable material selection and thickness settings—for example, the first and second isolation layers are 0.11mm-0.13mm thick, and the third isolation layer is 0.12mm-0.14mm thick; the first and second thin film layers are 0.11mm-0.15mm thick, and the third thin film layer is 0.14mm-0.16mm thick—the overall structure of the tape is stable and its performance is reliable.
[0018] In use: The first film layer 311 and the second film layer 312 are made of polyvinylidene fluoride (PVDF) film. PVDF has good mechanical properties, chemical corrosion resistance, and heat resistance. It can resist the erosion of various chemicals and maintain stable physical properties within a certain temperature range. The third film layer 313 is made of polytetrafluoroethylene (PTFE) film. PTFE has extremely low surface energy, excellent chemical stability, and high temperature resistance. It hardly reacts with any chemicals and can be used for a long time at high temperatures.
[0019] Synergistic Effect: The three thin film layers are stacked to form a dense protective barrier. The polyvinylidene fluoride (PVDF) film layer provides flexibility and mechanical strength, while the polytetrafluoroethylene (PTFE) film layer enhances the protective film's resistance to chemical corrosion and high-temperature limits. This structure allows the protective film to effectively protect the internal insulation and adhesive layers from damage by external chemicals and high temperatures. The first and second isolation layers 321 and 322 are glass fiber layers. Glass fiber is an inorganic non-metallic material with good thermal insulation properties, chemical stability, and mechanical strength. Its low thermal conductivity effectively blocks heat transfer. The third isolation layer 323 is a ceramic fiber layer. Ceramic fiber is a new type of lightweight refractory material with excellent properties such as high-temperature resistance, thermal insulation, and sound absorption. At high temperatures, ceramic fiber maintains a stable structure and performance, further enhancing the thermal insulation effect. The three isolation layers together constitute the thermal insulation layer. The glass fiber layer initially blocks heat, reducing the rate of heat transfer. The ceramic fiber layer then functions at higher temperatures, further preventing heat penetration. By combining different materials and setting a reasonable thickness, the heat insulation layer can provide reliable heat insulation protection for the tape in high-temperature environments. The adhesive layer 33 mainly serves to adhere and fix the tape. It enables the high-temperature tape to adhere firmly to the surface of the object to be bonded, ensuring that the tape will not easily fall off during use. At the same time, the adhesive layer also needs to have certain high-temperature resistance and chemical corrosion resistance to meet the requirements of high-temperature and electrolyte environments.
