[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1 , Figure 3 , Figure 4 The utility model provides an embodiment: a foam tape with an anti-deformation structure, comprising a base 1, which is the main structure of the entire tape, providing support and stability. It is usually made of foam material, which has softness and compressibility, can adapt to irregular surfaces and provide a certain degree of buffering. A spacer 2 is fixedly connected to the top of the base 1, and a breathable sheet 3 is fixedly connected to the top of the spacer 2. The spacer 2 is used to separate different functional layers to prevent mutual interference or damage between them. A plurality of water guide grooves 5 are provided on the top of the spacer 2, and a protective film 4 is fixedly connected to the top of the breathable sheet 3. The protective film 4 is used to protect the tape from damage. Honeycomb holes 6 are provided inside the breathable sheet 3. The breathable sheet 3 has honeycomb holes 6, which can allow air or water vapor to pass through, thereby reducing moisture accumulation between the bottom layer of the tape and the bonding surface, which helps to maintain long-term stability of the bonding performance. Reinforcement ribs 7 are provided inside the base 1, and the reinforcement ribs 7 are used to enhance the overall structural strength of the tape, especially when stretched or compressed, it can effectively prevent deformation or damage of the tape. A water-conducting component is disposed at the upper end of the base 1 to help maintain its adhesion and functionality and reduce the risk of failure due to the influence of moisture.
[0030] Reference Figure 4 The water guide component includes an isolation sheet 2, and a plurality of water guide grooves 5 are provided on the top of the isolation sheet 2, the main purpose of which is to manage and guide the potential flow of water to prevent the negative impact of water on the tape and its adhesive surface.
[0031] Reference Figure 2 , Figure 3 , Figure 4The material of the base 1 is polyethylene. The base 1 has good chemical corrosion resistance, wear resistance and mechanical strength, and is suitable for supporting and protecting the core part of the structure. The material of the isolation plate 2 is carbon fiber. The water guide groove 5 is opened on the top inner wall of the isolation plate 2 to increase its air permeability and reduce weight while maintaining the strength and stability of the structure. The material of the breathable sheet 3 is polyethylene. The honeycomb hole 6 is opened on the inner wall of the breathable sheet 3. The honeycomb hole 6 helps to effectively manage air flow and humidity control. The outside of the reinforcing rib 7 is fixedly connected to the inner wall of the base 1. The main function of the reinforcing rib 7 is to further enhance the structural stability and overall bearing capacity of the base 1, especially when facing external forces and stresses. It can effectively disperse and withstand pressure. The material of the protective film 4 is polyester film PET to improve its tensile strength and tear resistance, which can effectively extend the service life of the product and improve its performance stability under various environmental conditions.
[0032] Working principle: When in use, the protective film 4 is pressed, and the protective film 4 applies pressure to the breathable sheet 3. The protective film 4 moves downward with the breathable sheet 3, the breathable sheet 3 moves downward with the isolation sheet 2, and the isolation sheet 2 moves downward with the base 1, so that the tape is tightly sealed with the object. After sealing, the gas inside it exchanges with the outside air through the honeycomb holes 6 on the breathable sheet 3, which helps to keep the surface and inside of the packaged items dry, reduce the accumulation of moisture, and thus reduce the risk of mold and mildew. When the water droplets condensed inside the tape flow out through the water guide 5 on the isolation sheet 2 in a humid environment, it can effectively resist the negative effects of humidity and moisture on the adhesive properties of the tape, and maintain its adhesion and strength under different climatic conditions.
