Abstract

The invention relates to the technical field of acoustic boards, and discloses a light renewable resource acoustic board which is prefabricated with solid waste acoustic materials in an adding reinforced manner. The aggregate size of the solid waste acoustic materials is not larger than 20mm, the compressive strength of the solid waste acoustic materials is higher than 10MPa, and the acoustic absorption coefficient of the solid waste acoustic materials is larger than 0.65. By an assembled production and construction mode, all prefabricated parts are prefabricated in a factory, transformed to asite and directly assembled, the acoustic board is easy to operate, good in performance and short in construction period, resources are saved, environments are protected, and the requirements of green energy-saving ecological development are met. The problems of low industrial waste use ratio, environmental pollution and the like are solved, the production cost of the acoustic board is reduced, and the mechanical property, the fire resistance and the durability of the acoustic board are improved.

Description

technical field [0001] The invention relates to the technical field of noise pollution control, in particular to a light-weight renewable resource sound-absorbing panel and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's quality of life and the increasing awareness of environmental protection, their requirements for the living environment have also gradually increased. The problem of noise control has attracted the attention of governments and scientific and technological workers in various countries. Sound-absorbing materials can control noise pollution from three aspects: the source of noise generation, the process of transmission, and the protection of terminal victims. It is the most effective means of applying noise pollution. Most of the sound-absorbing materials are loose and porous materials, such as slag wool, glass wool, polyurethane foam, etc. The sound-absorbing mechanism is that the sound w...
