The composite sound isolating material with polymer as matrix is developed in recent years, and such material uses heterogeneous composite material system, in material
It is internally formed the different multiple solutions structure of density.It had both had efficient sound insulation, sound absorbing capabilities, and with light weight, processability
Can be good, corrosion-resistant many advantages, such as；But sound insulating material similar with most of macromolecular materials, being prepared using multiphase complex technique
Sound insulation frequency range still concentrate on medium-high frequency area（500~5 000 Hz）, the barriering effect to low frequency noise is good.
From sound transmission Analysis on Mechanism, if the eigentone of material is close with acoustic wave vibrations frequency, sound
Transmission effect is good, soundproof effect is poor.Therefore, material soundproof effect is improved, in addition to reflection of the raising material to sound, it is necessary to
Fissipation factor of the material in the range of temperature in use is improved, increases the consumption to vibrational energy.Therefore, fissipation factor high is selected
Material is to solve the key that low frequency noise is intercepted for protective articles.
