Description
Technical field
The present invention relates to new material technology field, specifically, be the preparation method of a kind of new building material with soundproof effect.
Background technology
Deadener refers to block sound transmission or weaken a class material, component or the structure of transmission acoustic energy, it is characterized in that heavier mass density is higher, such as steel plate, stereotype, concrete walls, brick wall etc..
Sound insulation refer to by certain article sound or Noise insulati on, cut off, separation etc., be therefore accomplished by deadener.The decibels that the incident acoustic energy of material side is relevant to the transmission acoustic energy of opposite side is exactly the sound transmission loss of this material, generally with symbol R(dB) represent.
Deadener or component, can be different because of use occasion, and method of testing is different and the soundproof effect that draws is different.For deadener, transmission acoustic energy to be weakened, stop the propagation of sound, cannot as sound-absorbing material porous, loose, ventilative, its material should be weight and closely knit, such as class materials such as steel plate, stereotype, brick walls on the contrary.The requirement of deadener material is closely knit imporosity or gap；There is bigger weight.Owing to this kind of deadener is closely knit, it is difficult to absorb and pass through acoustic energy and reflect energy by force, so its sound absorption qualities is poor.Deadener can make transmission sound energy attenuation to the 10 of incident acoustic energy-3～10-4Times or less, for convenience of express, the metering method of its sound transmission loss decibel represents.
A lot of aperture is had, after sound wave is entered, it may occur that reflection, so after the superposition of sound wave, sound will diminish, so sound-absorbing material is to prevent echo, is commonly used in film studio, and cinema etc. tends to have the place of echo inside sound-absorbing material.
And deadener is that sound is stoped outside, it is commonly used in the place that the privacy such as bedroom are higher.
Prior art is when using the sound-insulating structure of the preparation such as lead, concrete, owing to these materials exist difficult forming, and the unit mass problem such as heavily, limit its application.Macromolecular material light weight, easy-formation, but soundproof effect is the best, the important directions that exploitation sound barrier is effective, easy-formation, lightweight deadener are deadener development.
Summary of the invention
