Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fireproof tapes, and more particularly to a high-temperature resistant flame-retardant tape. Background Art
[0002] Currently, high-temperature flame-retardant tapes on the market are primarily used for high-temperature protection of electronic components, circuit boards, and various industrial equipment. However, while existing flame-retardant tapes exhibit a certain flame-retardant effect in high-temperature environments, their heat resistance is limited, and they are prone to delamination, decreased bond strength, or deformation. Furthermore, after long-term exposure to high temperatures, some flame-retardant materials can age, resulting in a decrease in flame-retardant effectiveness. This is particularly prone to occurring in environments with sustained high temperatures, such as those found in industrial equipment like motor coils, cables, and generators. Therefore, there is an urgent need for a high-temperature flame-retardant tape that can maintain good adhesion and stability over time in high-temperature environments. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-temperature resistant flame-retardant tape to solve the problem that the existing flame-retardant tape in the above-mentioned background technology has a certain flame-retardant effect in a high-temperature environment, but its temperature resistance is limited, and the tape is prone to delamination, decreased bonding strength or deformation.
[0004] The utility model provides the following technical solution: a high-temperature resistant flame-retardant tape, comprising an outer flame-retardant layer, the side projection shape of the outer flame-retardant layer being C-shaped, the structural material of the outer flame-retardant layer being polytetrafluoroethylene, an intermediate flame-retardant layer being fixedly installed inside the outer flame-retardant layer, the structural material of the intermediate flame-retardant layer being fumed silica, a bottom support layer being fixedly installed at the bottom end of the intermediate flame-retardant layer, the bottom support layer being glass fiber, an adhesive being fixedly installed at the bottom end of the bottom support layer, the adhesive being organic silica gel, and a nano-aluminum oxide coating being connected between the outer flame-retardant layer, the intermediate flame-retardant layer and the bottom support layer. The outer flame-retardant layer features a C-shaped side projection, enhancing the tape's adaptability. The outer layer, made of polytetrafluoroethylene, exhibits excellent high-temperature and chemical resistance, along with good mechanical strength. The intermediate flame-retardant layer, acting as a flame-retardant interlayer, provides excellent fire resistance and thermal insulation, ensuring flame retardancy at high temperatures. The bottom support layer enhances the tape's mechanical strength and heat resistance, ensuring it will not deform at high temperatures. The adhesive provides strong adhesion at high temperatures, while the addition of a nano-alumina coating increases interlayer bonding strength, further enhancing the tape's heat resistance and resistance to delamination. This effectively addresses the problem of existing flame-retardant tapes, which, despite exhibiting a certain flame-retardant effect in high-temperature environments, have limited heat resistance and are prone to delamination, decreased bond strength, or deformation.
[0005] Furthermore, an elastic layer is fixedly mounted on the top of the bottom support layer. The top of the elastic layer is fixedly connected to the bottom of the intermediate flame-retardant layer. The elastic layer is evenly distributed with multiple through-holes. The elastic layer is made of silicone rubber. The use of this highly elastic elastic layer improves the tape's impact resistance while maintaining good flexibility, ensuring adhesion even on complex surfaces. The uniform through-holes in the elastic layer enhance the material's breathability, preventing excessive heat accumulation within the tape at high temperatures and avoiding localized overheating.
[0006] Furthermore, a sound insulation pad is fixedly mounted on top of the intermediate flame-retardant layer. The top of the pad is fixedly connected to the bottom of the outer flame-retardant layer. The pad is made of a foam material. This improves the tape's sound and heat insulation properties. The foam material has low thermal conductivity, effectively preventing heat from conducting downward, further enhancing the tape's high-temperature protection. Its soft structure also increases the tape's flexibility, ensuring adaptive adhesion when used on different surfaces.
[0007] Furthermore, the top of the sound insulation pad is uniformly provided with sound insulation grooves, which are evenly filled with sound insulation rubber. This filling not only enhances the sound insulation effect of the tape but also provides additional structural support for the tape in high-temperature environments. The sound insulation rubber has excellent sound absorption capabilities and can effectively reduce the noise generated by mechanical equipment during operation, which is particularly beneficial in high-noise environments in industrial applications.
[0008] Furthermore, the outer flame-retardant layer is evenly provided with a plurality of heat dissipation holes. The heat dissipation holes can effectively improve the heat dissipation capacity of the tape, quickly reduce the surface temperature, prevent heat accumulation, further extend the service life of the tape, and avoid overheating that leads to decreased adhesion or degradation of material properties.
[0009] Furthermore, the top of the outer flame-retardant layer is fixedly mounted with multiple anti-skid ribs, and the outer surface of the outer flame-retardant layer is provided with a layer of UV-resistant film. The anti-skid ribs can add additional friction to the surface of the tape, improving its anti-skid effect during installation and use. The UV-resistant UV film covering the outer surface protects the tape from long-term exposure to sunlight and ultraviolet rays, preventing material aging and performance degradation, and extending the service life of the tape, making it particularly suitable for outdoor high-temperature or high-intensity environments.
[0010] The technical effects and advantages of this utility model are:
[0011] 1. The utility model is provided with an outer flame retardant layer, an intermediate flame retardant layer, a bottom support layer, and an adhesive, which effectively solves the problem that the existing flame retardant tape has a certain flame retardant effect in a high temperature environment, but its temperature resistance is limited, and the tape is prone to delamination, decreased bonding strength or deformation.
[0012] 2. The utility model is provided with an elastic layer. By using the elastic layer, this highly elastic material can improve the impact resistance of the tape while maintaining good flexibility to ensure that it can fit on complex surfaces. The elastic layer is designed with uniform through holes to enhance the air permeability of the material, which can prevent excessive heat accumulation inside the tape at high temperatures and avoid local overheating problems.
