High-density sound-absorbing panels

Abstract

This invention provides a high-density sound-absorbing panel, which is obtained by hot-pressing a non-woven fiber layer. The non-woven fiber layer comprises an adhesive fiber and a flame-retardant fiber. Based on the total weight of the non-woven fiber layer, the adhesive fiber content is 10 wt% to 40 wt%, and the flame-retardant fiber content is 15 wt% to 60 wt%. The density of the high-density sound-absorbing panel is greater than 500 grams per square yard. The high-density sound-absorbing panel of this invention has excellent sound absorption capabilities and also simplifies the installation process of sound insulation and absorption projects, reduces material costs, and expands its application range.
