Description
Technical field
The invention discloses a kind of preparation method of the special sound-absorbing material of interior decoration, belong to building and ornament materials and prepare skill
Art field.
Background technology
In today's society, noise pollution have become after after water pollution, atmosphere pollution by of interest main of world wide
One of problem of environmental pollution.In recent years, with the continuous improvement and the increasingly enhancing of environmental consciousness of people's quality of the life, people couple
The requirement of living environment is also stepped up, and the control problem of noise has caused people's most attention.
The conventional means that sound insulation noise reduction is improvement noise pollution is carried out using sound-absorbing acoustic material.Therefore, various sound absorbers
Material is widely used in Noise measarement, and with the continuous growth of sound-absorbing material consumption, people it is also proposed higher to its performance
It is required that, from realizing single sound absorbing capabilities to having the performance transitions such as high acoustic absorption, dicoration, economy and the feature of environmental protection concurrently.
Acoustic material is used to suppress sound transmission, and sound-absorbing material is then used to reduce sound reflection.According to the structure of material
Difference, sound-absorbing material can be divided into porous, resonance, the class of special construction 3.Current porous sound absorbing materials application is the most extensive, main bag
4 classes such as organic fiber, inorfil, inorganic foamed and foamed plastics are included, its surface is mutually passed through rich in pore between hole and hole
It is logical, and it is deep into internal layer.But although traditional sound-absorbing material can possess certain sound-absorbing effect, the frequency range of sound-absorbing compared with
Narrow, only centering high-frequency sound has good assimilation effect, poor to low frequency sound absorption effect, and the feature of environmental protection is not good, easily
Cause pruitus and respiratory tract anaphylaxis, be hazardous to the human body, unsuitable interior is used, limit using and pushing away for sound-absorbing material
Extensively.Therefore, a kind of special sound-absorbing material of interior decoration with wide sound-absorbing frequency range is researched and developed to have important practical significance.
The content of the invention
