Abstract
The utility model provides a noise proof non -woven fabrics of can eliminating noise, the non -woven fabrics lower floor that includes the non -woven fabrics upper strata and be located non -woven fabrics upper strata below inserted and put a metal thin film layer between non -woven fabrics upper strata and the non -woven fabrics lower floor between metal thin film layer and the non -woven fabrics upper strata with be provided with sound absorbing layer and lower sound absorbing layer between metal thin film layer and the non -woven fabrics lower floor respectively, go up sound absorbing layer and sound absorbing layer down respectively to non -woven fabrics upper strata and non -woven fabrics lower floor extend there are a plurality of sound absorbing layer branches, just the upper surface on non -woven fabrics upper strata and the lower surface of non -woven fabrics lower floor still respectively the equipartition have the appearance chamber of indent. The utility model discloses utilizing the soft foaming layer of polyurethane to form the produced vibrations of sound and absorbing and the separation, recycle the syllable -dividings effect that metal thin film layer is good, carry out further reflection to sound, each concave cavity can play the effect of cavity separation to sound simultaneously, and the effect that disperses the sound wave isolation then can be played by sound absorbing layer branch in addition.
Description
Technical field
The utility model relates to a kind of non-woven fabrics, provides a kind of non-woven fabrics of sound insulation of eliminating the noise.
Background technology
Non-woven fabrics is not only commonly used by people in dressing, and is also widely used in indoor and outdoor decoration.Along with the growth in the living standard of people, the quickening of rhythm, dwelling environment is more and more noisy, and people want seeking peace and quiet in noisy surroundings.Therefore, the non-woven fabrics with noise elimination effect is valued by the people just more and more, has been widely used in the places such as concert hall, studio hall, cinema, conference room, karaoke chamber, can have completely cut off with external sound, keeps the privacy in room.But the soundproof effect of the noise elimination non-woven fabrics on market is unsatisfactory, do not reach and well eliminate the noise and erasure effect, people wish that a kind of novel noise elimination non-woven fabrics solves this problem.
Utility model content
Therefore, in order to solve prior art Problems existing, the utility model provides a kind of non-woven fabrics of sound insulation of eliminating the noise.
For solving this technical problem, the utility model takes following scheme: a kind of non-woven fabrics of sound insulation of eliminating the noise, comprise non-woven fabrics upper strata and be positioned at the non-woven fabrics lower floor below non-woven fabrics upper strata, a metal film layer is gripped with between described non-woven fabrics upper strata and non-woven fabrics lower floor, sound absorbing layer and lower sound absorbing layer is respectively arranged with between described metal film layer and non-woven fabrics upper strata and between described metal film layer and non-woven fabrics lower floor, described upper sound absorbing layer and lower sound absorbing layer are extended with a plurality of sound absorbing layer branch respectively to described non-woven fabrics upper strata and non-woven fabrics lower floor, and the soffit of the upper surface on described non-woven fabrics upper strata and non-woven fabrics lower floor is also evenly equipped with the cavity volume of indent respectively.
Further improvement: described upper sound absorbing layer and lower sound absorbing layer are flexible polyurethane foaming layer.
Further improvement: the cross section of described sound absorbing layer branch is circular, and the diameter of this sound absorbing layer branch is 2.5-3.5mm.
Further improvement: spaced apart between described sound absorbing layer branch and the cavity volume of each indent.
By adopting preceding solution, useful aspect of the present utility model is: the particular design of each level order of the utility model is through repetition test and draws, it not simple superposition, this non-woven fabrics utilizes flexible polyurethane foaming layer form absorption to the vibrations that sound produces and intercept, the soundproof effect that recycling metal film layer is good, sound is further reflected, each indent cavity volume then can play the effect of cavity blocking to sound simultaneously, the design of sound absorbing layer branch then can play the effect carrying out the sound wave come from external environment condition to disperse isolation in addition, effectively can strengthen the soundproof effect of other sound-insulating structures, the sound wave that the quadruple sound-insulation structure of this non-woven fabrics design makes the installation environment of this non-woven fabrics reduce from external environment condition disturbs, thus reach good soundproof effect, the decorations of indoor and outdoor can be widely used in.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, the utility model embodiment discloses a kind of non-woven fabrics of sound insulation of eliminating the noise, the non-woven fabrics lower floor 2 comprising non-woven fabrics upper strata 1 and be positioned at below non-woven fabrics upper strata 1, a metal film layer 3 is gripped with in the present embodiment between described non-woven fabrics upper strata 1 and non-woven fabrics lower floor 2, sound absorbing layer 4 and lower sound absorbing layer 5 is respectively arranged with between described metal film layer 3 and non-woven fabrics upper strata 1 and between described metal film layer 3 and non-woven fabrics lower floor 2, described upper sound absorbing layer 4 and lower sound absorbing layer 5 all adopt the flexible polyurethane foaming layer with good sound-absorbing effect in the present embodiment, described upper sound absorbing layer 4 and lower sound absorbing layer 5 are extended with a plurality of sound absorbing layer branch 6 respectively to described non-woven fabrics upper strata 1 and non-woven fabrics lower floor 2, the cross section of described sound absorbing layer branch 6 is circular, the diameter of this sound absorbing layer branch 6 is 2.7mm in the present embodiment, in actual production, as long as the diameter of this sound absorbing layer branch 6 all can implement the purpose of this utility model between 2.5-3.5mm, and the soffit of the upper surface on described non-woven fabrics upper strata 1 and non-woven fabrics lower floor 2 is also evenly equipped with the cavity volume 7 of indent respectively, spaced apart between described sound absorbing layer branch 6 and the cavity volume 7 of each indent in the present embodiment.
By adopting preceding solution, useful aspect of the present utility model is: the particular design of each level order of the utility model is through repetition test and draws, it not simple superposition, this non-woven fabrics utilizes flexible polyurethane foaming layer form absorption to the vibrations that sound produces and intercept, the soundproof effect that recycling metal film layer is good, sound is further reflected, each indent cavity volume then can play the effect of cavity blocking to sound simultaneously, the design of sound absorbing layer branch then can play the effect carrying out the sound wave come from external environment condition to disperse isolation in addition, effectively can strengthen the soundproof effect of other sound-insulating structures, the sound wave that the quadruple sound-insulation structure of this non-woven fabrics design makes the installation environment of this non-woven fabrics reduce from external environment condition disturbs, thus reach good soundproof effect, the decorations of indoor and outdoor can be widely used in.
Although specifically show in conjunction with preferred embodiment and describe the utility model; this technical scheme method and access of specific implementation is a lot; the above is only preferred embodiment of the present utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
