Abstract
The utility model discloses a wall cloth, particularly to an acoustical absorption and sound insulation wall cloth. The acoustical absorption and sound insulation wall cloth is characterized in that the acoustical absorption and sound insulation wall cloth adopts hollow micropore polyester fiber material, the hollow micropore polyester fiber comprises fiber matrix, and a plurality of irregular micropores are arranged both on the surface of and inside the fiber matrix. Since the hollow micropore polyester fiber having a special structure is adopted, the acoustical absorption and sound insulation wall cloth has good high-frequency acoustical absorption performance. In addition, due to the cavity pore structure of fiber itself, a resonant acoustical absorption assembly can be effectively formed, and the resonant acoustical absorption frequency is transferred towards a low frequency direction, thereby increasing the low frequency acoustical absorption coefficient of material. And the acoustical absorption and sound insulation wall cloth also has the advantages of humidity absorption and ventilation.
Description
Technical field
The utility model relates to a kind of sound absorption sound insulation wall paper, belongs to the wall paper technical field.
Background technology
Along with creation and the use of various plant equipment, brought flourishing and progress to the mankind, but also produced more and more and more and more stronger noise simultaneously.The World Health Organization (WHO) studies show that, noise pollution not only can affect people's hearing, and can cause hypertension, heart disease, be losing one's memory, absent minded and other psychosyndrome.Noise pollution has been listed in the subject matter that the 21 century environmental pollution is controlled, and therefore studying sound-proof material also becomes and reduce one of direction that the noise pollution emphasis breaks through.
existing studies show that, sound absorbing mechanism according to sound-absorbing porous material, textile material is loose because of it, soft, porous and have good high frequency sound absorbing capabilities, can be summed up as sound-absorbing porous material, its principle is: when sound wave incides the fabric surface, the vibration that sound wave produces causes textile material internal voids and the intrapore air movement of fiber, air itself has the effect of attenuate high frequency sound wave, air movement causes between yarn and yarn simultaneously, between fiber and fiber and the friction of fibrous inside hole wall, thereby because making part acoustic energy be converted into heat energy, friction and the effect of viscous force make acoustic attenuation, simultaneously the space in fabric and the air in hole and surrounding environment are carried out the heat-energy losses that heat interchange causes and are also caused sound energy attenuation, make textile material have good high frequency sound absorbing capabilities.At present, textile material reaches the sound absorption soundproof effect, mostly be by the different modes of production, as, increase the thickness, surfaceness, superficial density of textile material etc., but increase roughness when too thick noise is doubled when material is too wide, if increasing surface density material unit weight increases, internal void reduces, and the corresponding raising of acoustic impedance is affected again at raising effect of low-frequency sound absorption while high frequency acoustically effective.Existing with thin fiber layer fabric separately as acoustic absorbant, but its acoustically effective is relatively poor, if at material, air layer is set behind, cavity behind can make material to certain low frequency absorption performance is arranged, the high frequency acoustically effective is lower.Above when select making the acoustic absorbant mode, due to the phenomenon of restriction mutually that influences each other that each factor exists, must rationally control just and can reach certain effect, complex procedures not only, cost is also high.
The utility model content
The purpose of this utility model is, a kind of wall paper with outstanding sound-absorbing soundproof effect is provided.
The technical scheme that the utility model is taked is as follows:
A kind of sound absorption sound insulation wall paper is characterized in that: described sound absorption sound insulation wall paper adopts hollow micropore polyester fiber material, and described hollow micropore polyester fiber comprises fibrous matrix, all is provided with several micropores in surface and the inside of fibrous matrix.
The beneficial effects of the utility model:
A kind of sound absorption sound insulation wall paper of the present utility model, adopt hollow micropore polyester fiber material to make, fibrous inside hole and fiber hole interconnect, when sound wave incides the fabric surface, cause on the one hand internal voids and the intrapore air movement of fiber, air movement causes between yarn and yarn, between fiber and fiber and the friction of fibrous inside hole wall, thereby make acoustic attenuation because the effect of friction and viscous force makes part acoustic energy be converted into heat energy; When air adiabatic compresses, heat interchange occuring constantly between air and hole wall, also can make acoustic energy be converted into heat energy and be attenuated, has good high frequency sound absorbing capabilities on the other hand.In addition, due to the cavity bore gap structure of fiber itself, can effectively form the resonance sound-absorbing assembly, the resonance sound-absorbing frequency is shifted to the low frequency direction, thus the low frequency absorption coefficient of increase material.Simultaneously, because fiber multihole has advantages of that moisture absorption is ventilative, also have three anti-and fire-retardant premium properties concurrently, filled up multiporous fiber and made the blank of sound-proof material in the wall paper area research is used.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Description of drawings:
Fig. 1 is the utility model sound absorption sound insulation wall paper structural representation;
Fig. 2 is the structural representation of the utility model hollow micropore polyester fiber.
Number in the figure: 1 is the hollow micropore polyester fiber, 2 sound absorption sound insulation wall papers, and 1-1 is fibrous matrix, 1-2 is micropore.
Embodiment:
As shown in Figure 1, sound absorption sound insulation wall paper 2 of the present utility model adopts hollow micropore polyester fiber 1, preferably adopts hollow micropore polyester fiber long filament pilotaxitic texture, and adopts the complex function finishing agent to carry out rear arrangement to it.
In conjunction with shown in Figure 2, described hollow micropore polyester fiber 1 comprises fibrous matrix 1-1, all is provided with several irregular micropore 1-2 in surface and the inside of fibrous matrix 1-1.
Adopt the hollow micropore polyester fiber long filament of said structure, the sound absorption sound insulation wall paper 2 of preparation, the sound absorption soundproof effect is obvious, and have hydroscopic fast-drying, three several functions such as anti-, fire-retardant concurrently, can develop multiple different tissues structure applications to soundproof wall cloth field, fill up multiporous fiber and made the blank of sound-proof material in the wall paper area research is used.
