Abstract

A building sound absorbing material is disclosed. The building sound absorbing material comprises 10-15 parts by weight of phenolic resin, 10-15 parts by weight of polypropylene, 5-20 parts by weight of diatomite, 6-8 parts by weight of hollow glass microbeads, 5-15 parts by weight of perlite, 1-3 parts by weight of barium sulfate, 1-5 parts by weight of titanium dioxide, 6-10 parts by weight of straw, 1-5 parts by weight of a coupling agent and 1-2 parts by weight of a thickening agent. The building sound absorbing material has an excellent sound absorbing function and is capable of effectively absorbing noise in the environment and reducing noise hazards. The building sound absorbing material is nontoxic and harmless, can be used as inner wall and outer wall materials, and is wide in uses.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a building sound-absorbing material. Background technique [0002] With the acceleration of urbanization, urban noise has increasingly become an invisible killer that endangers the health of ordinary people. Noise will not only affect people's normal sleep, but also affect their mood, making people upset and irritable, and even cause physical injury. Long-term exposure to noise It will lead to the decline of human body function and have great harm to human physical and mental health. At present, there is no good solution for urban noise except control. [0003] Therefore, prior art also needs further development and improvement. Contents of the invention [0004] The object of the present invention is to provide a building sound-absorbing material, which aims to absorb noise in the environment and reduce the harm of noise to the human body. [0005] Technical scheme of the ...
