Sound absorption material and preparation method thereof

Abstract

The invention discloses a sound-absorbing material, which comprises the following raw materials in parts by weight: 18-27 parts of sepiolite, 15-25 parts of modified starch, 13-28 parts of attapulgite clay, 7-10 parts of modified tree ash, 10-30 parts of ceramsite, 9-18 parts of calcined bauxite, 4-6 parts of nano wollastonite powder, 8-16 parts of styrene-acrylic emulsion, 5-12 parts of graphite powder, 5-15 parts of polypropylene fiber, stearin Calcium acid 2-3 parts, aluminum hydroxide 1-2 parts, foaming agent 2-3 parts, sodium polyphosphate 1.3-2.3 parts, polyacrylamide 3-5 parts, rare earth catalyst 1.5-2.5 parts. The sound-absorbing material has the advantages of low cost, low density, convenient use, high structural strength, good sound-absorbing and noise-reducing effects, excellent chemical stability, and is suitable for various occasions.

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...

Problems solved by technology

[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. It is not suitable for use as a building decoration material due to its shortcomings such as poor quality and heavy weight when used, so the existing building materials are still not ideal when used.
