Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, a noise-reducing and sound-absorbing wall cloth comprises an inner layer 5 and an outer layer 1, wherein a first sound-absorbing layer 3 and a second sound-absorbing layer 4 are arranged between the inner layer 5 and the outer layer 1 to reduce noise and protect the wall cloth, so that external vibration noise can be reduced and absorbed, and the indoor silencing comfort can be improved;
the sound absorption layer I3 and the sound absorption layer II 4 have good sound absorption performance, and adopt a resin foaming layer structure, particularly a polyurethane foaming layer, so that a soft and loose structure is formed inside the wall cloth, and the noise reduction and sound absorption effects of the wall cloth are improved;
the first buffer hole 6 and the second buffer hole 7 are respectively arranged on the opposite sides of the first sound absorption layer 3 and the second sound absorption layer 4, the first buffer hole 6 and the second buffer hole 7 can increase a concave-convex structure in the sound absorption layer structure, so that the sound waves can be buffered and reduced in the sound absorption layer structure, and the mute effect of the indoor environment is improved; wherein the concrete structure of buffer hole one 6 and buffer hole two 7 can set up to the blind hole that the cross-section is six deformation structures to the aperture enlarges gradually towards the opening direction, dwindles gradually towards the downthehole department in, thereby can form the passageway that the aperture changes in inside, improves the sound wave and subducts the effect at the opposite directions wherein, further improves the inside stability of wall paper. Can be the structure of misplacing each other with setting up between buffer hole one 6 and the two 7 of slow punch a hole, avoid buffer hole one 6 and slow punch a hole two 7 coincidence each other and lead to this position to form thinly, the lower position of intensity to can strengthen the stability of each position of holistic wall cloth.
In order to increase the buffering effect between the first sound absorption layer 3 and the second sound absorption layer 4, opposite hemispherical depressions 8 are preset on one opposite sides of the first sound absorption layer 3 and the second sound absorption layer 4, in the process of bonding and compounding the two layers, the depressions 8 on the two sides are opposite and surround to form a cavity, and the depressions 8 are filled with buffering fillers 9; the structure of the recess 8 can increase the buffer space between the sound-absorbing layers, increase the buffer absorption effect on external impact and sound wave oscillation, and improve the noise reduction effect, and the buffer witness effect on the inner side of the wall cloth can also be improved by filling the attached buffer filler 9; as for the selection of the buffer filler 9, an elastic foaming material can be adopted, for example, a foaming polyurethane foam is also adopted, and bamboo charcoal antibacterial particles are mixed in the foaming polyurethane foam in the stirring and forming process, and the bamboo charcoal antibacterial particles can absorb peculiar smell, play a role in purifying air, inhibit the breeding of bacteria such as mold and the like, and play a healthy and environment-friendly role; the foamed polyurethane foam has a microporous structure, and can be penetrated by air to form a breathable structure.
