Description

Technical Field

[0001] This utility model relates to the field of automotive sound-absorbing cotton technology, and in particular to an automotive sound-absorbing cotton based on a wrap-around adhesive installation. Background Technology

[0002] The wrap-around adhesive installation allows the sound-absorbing cotton to fit tightly into various parts of the car's interior, effectively reducing installation gaps and maximizing sound absorption. Compared to traditional installation methods, it can better cover irregularly shaped surfaces, ensuring a larger contact area between the sound-absorbing cotton and the car body.

[0003] However, the wrap-around adhesive installation of automotive sound-absorbing cotton in related technologies still has shortcomings. Although automotive sound-absorbing cotton is beneficial for sound absorption and insulation, its corrosion resistance, high temperature resistance, and flame retardancy are poor, and it does not have fireproofing effect, which reduces its effectiveness. In addition, it requires applying adhesive first and then pressing to stick, making the installation process relatively troublesome. Therefore, we propose an automotive sound-absorbing cotton based on wrap-around adhesive installation to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing a car sound-absorbing cotton based on a wrap-around adhesive installation.

[0016] This utility model has a reasonable structural design. The automotive sound-absorbing cotton layer is composed of a butyl rubber layer, an automotive sound-absorbing cotton body, a foamed flame-retardant material layer, and aluminum foil. This makes the automotive sound-absorbing cotton in this article not only have a good sound absorption and noise reduction effect, but also have corrosion resistance, high temperature resistance, and flame retardancy, resulting in better fire resistance and safer use. It also has a built-in adhesive layer. When pasting, the release film can be removed, and the automotive sound-absorbing cotton can be wrapped and pasted through the adhesive layer, making the installation more convenient and efficient.
