A common sound absorbing material is a microporous metal plate, and after the microporous metal plate is glued to a perforated substrate, a decorative coating is disposed on the surface of the microporous metal plate, for example, the inventor applies for a patent in 2022, 3 and 29, entitled "a composite metal sound absorbing plate" and application number "202220694154.5". However, this product has several problems: 1. because the mould for punching the micropores needs to punch the micropores on the metal plate, the wear is rapid, the size difference exists in the processing of the micropores, and the strip mark is easy to generate; 2. the noise reduction coefficient performance is not high enough, and the noise reduction coefficient is about 0.6.
Disclosure of utility model
Aiming at the problems, the utility model provides the sound-absorbing film-coated plate, which not only can solve the problem of appearance stripe printing, but also can remarkably improve the noise reduction coefficient, thereby better meeting the requirement of sound-absorbing performance.

The density of the micropores arranged on the decorative film 1 is greater than the density of the perforations arranged on the perforated substrate 3, and the pore diameter of the micropores is smaller than the pore diameter of the perforations.
Preferably, the decorative film 1 has a porosity of 1.8%, a hole diameter of 0.3mm, and a hole pitch of 2mm. The perforation ratio of the perforated substrate 3 was 24.2%, the hole diameter was 5mm, and the hole pitch was 9mm.
Further, the perforated substrate 3 is a perforated inorganic plate, a perforated metal plate or a perforated metal composite plate.
Further, the decorative film 1 and the perforated substrate 3 are fixedly connected through the adhesive layer 2.
Further, the decorative film 1 is coated on the outer side surface of the perforated base plate 3, the inner side of the perforated base plate 3 is mounted on the wall surface 5, and a cavity 4 is reserved between the perforated base plate 3 and the wall surface 5.
The utility model effectively solves the problem of appearance strip printing caused by the traditional mode of forming micropores on the metal plate by forming the micropores on the decorative film; more importantly, the scheme also overcomes the prejudice of the traditional technology, breaks the technical barrier that the traditional technology seals the sound absorption holes through the decorative film, and directly opens micropores on the decorative film, so that on one hand, the holes in the metal plate can better receive and absorb sound waves, on the other hand, the sound energy can be absorbed through vibration of the decorative film, and further, the noise reduction coefficient can be obviously improved finally, and the NRC can reach about 0.7.

It should be explained that fig. 1-3 are schematic diagrams in this case, and do not represent the actual thickness, actual size and actual proportion of each portion; in the figure, 1 is a decorative film, 2 is an adhesive layer, 3 is a perforated substrate, 4 is a cavity, 5 is a wall body, and 50 is a leveling layer.
Detailed Description
In order to clearly illustrate the technical features of the present patent, the following detailed description will make reference to the accompanying drawings.
As shown in fig. 1-2, the scheme comprises a perforated substrate 3 and a decorative film 1, wherein the decorative film 1 is coated on one side surface of the perforated substrate 3, a plurality of micropores are formed in the decorative film 1 to form a super microporous film, a plurality of perforations are formed in the perforated substrate 3, and all or part of the micropores are communicated with the perforations. When in processing, micropores can be formed in the mode of puncturing holes through the needle roller, and the abrasion to the needle roller is almost zero because the rigidity of the decorative film is small, so that the decorative film with consistent micropores can be obtained only by ensuring the consistent diameters of the needles, and the problem of appearance strip printing caused by the traditional mode of puncturing the micropores on the metal plate is effectively solved; after the glue is applied, the metal plate can be attached to the decorative film, and the decorative film is trimmed, so that the plate trimming process is reduced, and the material utilization rate can be improved; more importantly, the scheme directly opens the micropore on the decorating film, on the one hand, the hole in the metal plate can better receive and absorb sound waves, on the other hand, the sound energy can be absorbed through the vibration of the decorating film, and then the noise reduction coefficient can be obviously improved finally, and the NRC can reach about 0.7.
The density of the micropores arranged on the decorative film 1 is greater than the density of the perforations arranged on the perforated substrate 3, and the pore diameter of the micropores is smaller than the pore diameter of the perforations. In this way, most of micropores are communicated with the perforations, so that the effects of receiving and absorbing sound waves by the scheme and absorbing sound energy by vibration of the decorative film are enhanced.
Preferably, the decorative film 1 has a porosity of 1.8%, a hole diameter of 0.3mm, and a hole pitch of 2mm. The perforation ratio of the perforated substrate 3 was 24.2%, the hole diameter was 5mm, and the hole pitch was 9mm.
The perforated substrate 3 is a perforated inorganic plate, a perforated metal plate or a perforated metal composite plate, and the metal composite plate is a plate formed by compounding a metal material with an inorganic material or a non-metal material, or is a plate formed by compounding different metal materials.
The decorative film 1 and the perforated substrate 3 are fixedly connected through the adhesive layer 2.
The decorative film 1 is coated on the outer side surface of the perforated base plate 3, the inner side of the perforated base plate 3 is arranged on the wall surface 5, a cavity 4 is reserved between the perforated base plate 3 and the wall surface 5, and the wall surface 5 is provided with a leveling layer 50 connected with the wall surface. Therefore, the ultra-microporous metal mold with small rigidity and tension in the tensile state can be matched with a closed air layer (namely a cavity) with proper thickness to form a resonance system consisting of a film and the air layer, and further has a larger sound absorption effect near the resonance frequency of the system.
The sound absorption process of this case is as shown in fig. 3, and in contrast, traditional abatvoix includes decorative coating, micropore metal sheet, glue, perforation base plate, cavity in proper order, and this case then belongs to a micropore film composite construction, includes decorative film (belongs to a super micropore film), adhesive layer, perforation base plate, cavity in proper order, its sound absorption characteristics: when the frequency of the incident sound wave is close to the natural frequency, the air vibration in the structure is strong, the damping, the sound energy loss and the sound absorption are high. As shown in the figure, most of sound is transmitted through the decorative film, resonance can be generated when the sound is transmitted through the decorative film, part of sound energy is consumed, and after that, the sound transmitted through the perforated substrate plate is reflected back and forth in the cavity to continue to absorb the sound, so that most of the sound energy is consumed, and finally, only a small part of the sound energy is reflected to the indoor space, so that the sound absorbing effect is better compared with that of the traditional technology.
While there have been described what are believed to be the preferred embodiments of the present utility model, it will be apparent to those skilled in the art that many more modifications are possible without departing from the principles of the utility model.
