Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of butyl rubber, in particular to a high-rebound and anti-deformation butyl rubber sealing tape. Background Art
[0002] Butyl rubber sealing tape has a wide range of applications in modern industry. With the continuous advancement of science and technology and the development of the industrial field, the requirements for sealing materials are becoming higher and higher. Butyl rubber has become one of the ideal materials for making sealing tapes due to its excellent airtightness, weather resistance and chemical stability. In many industries such as construction, automobiles, and ships, reliable sealing solutions are needed to prevent leakage and maintain environmental stability. Butyl rubber sealing tape meets the needs of these fields for high-quality sealing materials and provides effective protection and sealing for various projects and facilities.
[0003] When faced with some protection needs that have extremely high requirements for sealing performance, people often stretch butyl rubber sealing tape when using it, and then perform the fitting operation. However, when the tape is stretched, it will inevitably pull the unused part of the tape. As the stretching force continues to increase, the side wall of the tape will be stretched longer and longer, and correspondingly, the width of the tape will gradually shrink, and the entire tape body will be seriously deformed. The originally flat tape becomes twisted and irregular, and the adhesive layer that originally had strong viscosity will weaken its viscosity after stretching and deformation, resulting in the sealing effect of the entire tape becoming worse and worse, and the expected sealing effect cannot be achieved. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that the butyl rubber sealing tape is deformed by pulling so that the viscosity becomes poor and the sealing effect is insufficient. The utility model provides a high-rebound and anti-deformation butyl rubber sealing tape.
[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0006] A high-resilience, deformation-resistant butyl rubber sealing tape comprises a butyl rubber layer, a reinforcing layer is arranged on the top side of the butyl rubber layer, a backing layer is arranged on the top side of the reinforcing layer, a reinforcing layer is arranged on the bottom side of the butyl rubber layer, an adhesive layer is coated on the bottom sides of the butyl rubber layer and the reinforcing layer, a protective layer is wrapped around the bottom sides of the butyl rubber layer, the reinforcing layer and the adhesive layer, the front and rear ends of the protective layer are folded above the side wall of the butyl rubber layer, and the front and rear end outer edge portions of the protective layer wrap around the outer edge portions of the reinforcing layer and the backing layer.
[0007] Furthermore, the interior of the reinforcement layer contains a fiber layer and metal wires, which increase the strength and tensile strength of the tape.
[0008] Furthermore, the bottom edge of the backing layer and the top edge of the butyl rubber layer are closely fitted together, which can protect and fix the butyl rubber layer.
[0009] Furthermore, the interior of the reinforcing layer contains polyester fibers and nylon fibers, which can improve the strength and stability of the butyl rubber layer.
[0010] Furthermore, the protective layer includes a veneer area and a corner overlap area, the top side of the veneer area is located on the bottom side of the butyl rubber layer and the reinforcement layer, the side wall of the corner overlap area is folded upward, and the inner side of the corner overlap area is wrapped around the outer side of the reinforcement layer and the backing layer. When the corner overlap area is folded upward, it can protect the edge of the entire butyl rubber layer and the inner adhesive layer to prevent the edge of the butyl rubber layer from losing its stickiness.
[0011] Furthermore, the outer edge of the corner overlap area is arranged at the outer edge of the veneer area.
[0012] Compared with the prior art, the utility model provides a high-rebound and anti-deformation butyl rubber sealing tape, which has the following beneficial effects:
[0013] The high-resilience and anti-deformation butyl rubber sealing tape greatly improves the strength and tensile strength of the tape through the cooperation of the fiber layer and the metal wire inside the reinforcement layer. This not only ensures the reliability and stability of the tape when used in various harsh environments, but also enables it to withstand greater external pulling and high elastic stretching operations, and is not prone to breakage or damage and deformation. The bottom edge of the backing layer and the top edge of the butyl rubber layer are tightly fitted together. This tight fit can very effectively play a dual protection role, not only protecting the butyl rubber layer from erosion and damage by external factors, but also fixing the butyl rubber layer well, making it more stable and reliable during use.
[0014] The polyester fiber and nylon fiber in the reinforcing layer of the high-rebound and anti-deformation butyl rubber sealing tape are interwoven and tightly combined, and their synergistic effect greatly improves the strength of the butyl rubber layer. This allows the butyl rubber layer to withstand greater external forces and is not prone to breakage or damage. It also enhances its stability. When the protective layer is folded upward, it can fully protect the edge of the entire butyl rubber layer and the inner adhesive layer, effectively preventing the edge of the butyl rubber layer from losing its stickiness due to operations such as stretching, which not only ensures the overall performance and use effect of the tape, but also extends the service life of the tape.
