Background

With the development of society, people enjoy the technological progress to bring convenience, and various pollutions in life influence normal life, work and study of people. In particular, noise pollution is serious, and thus, various products having sound absorption and insulation effects are successively produced in accordance with the demand for reducing noise pollution. The sound-absorbing decorative plate is a plate-shaped material with sound-absorbing and noise-reducing functions, and is an ideal sound-absorbing decorative material. The existing sound absorption materials comprise sponge, polyester fiber, glass fiber and the like, but the sound absorption materials have low strength and are easy to deform, and are not beneficial to long-term use. In addition, the surface decorative layer is fixed by glue in the production process of the existing decorative plate, and the decorative plate is also fixed on a wall body by gluing in the installation process of the decorative plate, so that the installation is inconvenient, volatile substances of the glue are difficult to remove, certain pollution is brought to the indoor environment, and physical and psychological health is not facilitated. Finally, the traditional decorative sound-absorbing material is often limited due to the length and width specifications in application, for example, the maximum length of the decorative sound-absorbing material is generally not more than 2.4 m, and some aluminum alloy sections are frames and the sound-absorbing decorative plates filled with the sound-absorbing material are seriously deformed inwards after being compounded with surface fabrics, so that the seam error is large when the decorative sound-absorbing material is densely spliced, and the attractiveness is influenced. Therefore, it is necessary to design an environment-friendly sound absorption decorative plate which has high strength, good sound absorption effect, difficult deformation, environmental protection and convenient installation.
