Abstract

The invention relates to a sound absorbing wallpaper for lowering the harm of noise on the people, which is characterized in: by adopting the method of immersion, the wallpaper is repeatedly immersed into the solution that is refined by super-thin metal micro-powders, minerals and similar sound-absorbing particles, and then dried, so that the wallpaper has excellent broadband sound-insulating performance and high damping performance. The sound absorbing wallpaper has low price, convenient use and is completely suitable for houseroom or public occasions that need sound-insulation treatment.

Description

technical field [0001] The invention relates to home textile products, in particular to a sound-absorbing wallpaper. Background technique [0002] In recent years, the harm of noise to the human body has attracted more and more attention.
