Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of high strength sound material and preparation method thereof.
Background technique
With the progress of economic development and science, people's demands for quality of life are getting higher and higher.On the other hand, day is faced
The serious noise pollution of benefit, for people, a comfortable work living environment just seems especially urgent.Research shows that sound wave
When encountering acoustic barrier in communication process, a part of sound can be reflected, and a part of sound can be absorbed by barrier, and remainder is then saturating
Cross barrier.The ratio of the transmission sound intensity and incidence sound intensity levels is known as transmission coefficient.The sound insulation property of the smaller then material of transmission coefficient is better.
For single-phase homogeneous high molecular material, sound insulation effect obeys mass law, and the surface density of material is bigger, to sound
The albedo of sound is stronger.Macromolecule sound insulating material is exactly main by reflecting and scattering sound so that reaching reduces the one of noise
Class material.Macromolecule sound insulating material adds a large amount of high-gravity fillers by macromolecule resin and is combined, surface density with higher, because
This is with good sound insulation property.
Being attributed to particle with the raising of Inorganic Particle Filled Polymers based composites sound insulation property, that sound wave has occurred is more
Secondary reflection, scattering, refraction and diffraction and cause the propagation path of sound to increase, while to will lead to material viscous for the addition of inorganic particulate
Elasticity variation and consume more sound energy.A kind of inorganic filler of the hollow glass microbead as special construction, can fill poly-
It closes object based composites and obtains preferable sound insulation value, compared to traditional polymer matrix acoustic material, maximum feature is
Density is low, and good to low frequency noise soundproof effect.Moreover, hollow glass microbead has extremely low thermal conductivity, in high score
Hollow glass microbead is added in sub- material can greatly improve the heat-proof quality of material, this is for automobile, rail traffic, building etc.
There is significant application value to the demanding field of sound-insulating and heat-insulating equivalent comfort.
In addition, the characteristic impedance of material is adjusted by changing filler and compounding agent in matrix etc., formation has
The material of different acoustic impedances makes sound wave generate reflection in overlapping interface, is to reach raising material then by its superimposion
Expect a kind of good method of sound insulation value.The study found that by structure design introduce multilayered structure can effectively improve material every
Sound performance such as finds that the material of double-layer structure is better than the sound insulation property of single layer structure.
It is polymeric substrate that existing polymer-based acoustic material, which generally selects PVC, EPDM etc., while largely being added inorganic
The high-gravity fillers such as high-gravity filler, steel slag, waste rubber powder, glass fibre improve sound insulation drop to increase the modulus and density of material
It makes an uproar performance.Traditional polymer-based acoustic material there are sound insulation values it is poor, inflammable do not met greatly with density not environmentally lightweight hair
The disadvantages of opening up direction.For these disadvantages, also there are a large amount of novel sound insulating material products to come out, but not can solve traditional material mostly
Existing whole disadvantage.

Method, Publication No. CN202686211U disclose a kind of auto sound damping sheet, and Publication No. CN101691119A is disclosed
A kind of bullet train damping sound insulation sheet material and its manufacturing method, the number of opening are CN1583864A, disclose a kind of car sound insulation
The preparation method of damping noise-reducing sheet material, the above prior art all refer to compound by the simple superposition of blending or different function layer
Made of polymer-based sound-insulating and heat-insulating functional material, but effect of vibration and noise reduction is limited, and it is complicated to fabricate process, cost
It is higher.Publication No. CN102504388A discloses a kind of acoustic material, discloses one kind and is made of polyethylene and cenosphere
Acoustic material, the material flexibility is good, intensity is high, light weight, the scattering and refraction by hollow glass microbead to sound wave, can
To consume and sponge a part of low-frequency noise.But it only has single structure, do not have layer structure, medium-high frequency every
Shortcomings in terms of sound noise reduction.Publication No. CN103158314A, disclose a kind of MULTILAYER COMPOSITE environmental protection flame retardant sound insulation coiled material and
Preparation method, notification number CN102501504B disclose a kind of low-density polymer-based sound insulation and noise reducing material and its preparation
Method, the material being related to have alternating multilayered structure, and the alternate multiple by macromolecule dense layer and foaming layer is compound, it is intended to logical
It crosses foam process and realizes density difference between adjacent layer, thus light-weighted while improving sound insulation value, but in reality
In preparation process, foaming layer will affect the interface of layer and interlayer when die head is foamed, and string layer phenomenon easily occurs, leads to boundary
The destruction of surface layer alternate multiple composite construction, therefore it is not easily controlled the interface uniformity of alternate multiple composite construction, so that boundary
Reflex in face of sound weakens, and material entirety sound insulation property, which has no, to be significantly improved.
In summary, it is therefore desirable to a kind of better acoustic material, to improve the deficiencies in the prior art.
