Description

technical field [0001] The invention belongs to the technical field of sound-absorbing materials, and in particular relates to a sound-absorbing material and a preparation method thereof. Background technique [0002] At present, most of the building materials in the prior art are made of soil or cement and other inorganic materials, which not only wastes a lot of land resources and destroys the ecological environment, but also has high production costs and low sound-absorbing effects. Shortcomings such as poor quality and heavier weight during use are not suitable for use as building decoration materials, so the existing building materials are still not ideal when used. Contents of the invention [0003] The present invention provides a sound-absorbing material and a preparation method thereof, which solves the problems in the above-mentioned background technology. The sound-absorbing material has low cost, low density, convenient use, high structural strength, good sound...
