Description

[0001] The utility model relates to the field of construction and finishing materials, in particular to decorative and acoustic wall panels for interior decoration.

[0002] A well-known decorative panel [see Decorative panel TAGinterio™ DECO | taginterio] the surface of which is made of natural veneer, fineline veneer, HPL plastic, RAL / NCS paint, with an anti-vandal coating with a hardness of 6H.

[0003] A well-known acoustic panel [see Veneered decorative panels One from Varman.pro * VăRMAN.PRO], made of 100% natural materials: durable MDF base and natural wood veneer.

[0004] The disadvantages of these panels are that the materials used do not provide sufficient sound insulation and require considerable labor and additional material investment for installation. Attaching the panels to the wall requires the use of additional guides or mounting elements, which increases the labor intensity and cost of installation. This means that, as a rule, it is necessary to first attach the guides to the wall and then attach the panels themselves.

[0005] The technical result is to improve the sound-absorbing and noise-insulating characteristics of the panel.

[0006] The technical result is achieved by the wall acoustic panel comprising a face layer formed as a single panel and connected to an acoustic base made of non-woven material. The face layer is offset from the edge of the acoustic base, creating a hidden mounting groove for connecting the panels together.

[0007] The top layer consists of a base made of MDF, gypsum board, HDF, plywood, chipboard, or composite wood material, covered with natural or engineered wood veneer, or finished with paint. The non-woven material is made of polyester, including PET felt with a recycled polyethylene terephthalate content of 30-90% and / or polyester felt fabric, in which the acoustic base thickness is 3-25 mm, and the surface density is 300-2000 g / m. 2The face layer is connected to the acoustic base using metal staples or PVA glue, PUR glue, acrylic dispersion, or hot-melt adhesive. The face layer contains microperforations, linear grooves, or milled channels. The acoustic base contains additional perforations or acoustic channels. The back of the acoustic base contains elements for concealed installation: grooves, protrusions, holes, adhesive pads, and hook-and-loop elements. An intermediate layer—non-woven lining, cardboard, mesh material, or thin fiberboard—can be placed between the face layer and the acoustic base. The face layer can be solid, modular, or feature patterned markings.

[0009] Fig. 2 shows the bottom view of the wall acoustic panel.

[0010] Fig. 3 shows the wall acoustic panel.

[0011] Fig. 4 shows an example of connecting two wall acoustic panels using a hidden mounting groove.

[0012] Fig. 5 shows a photo of wall acoustic panels, the front layer of which is made in the form of natural wood veneer.

[0013] The wall acoustic panel includes a front layer 1 in the form of a solid panel, an acoustic base 2. The front layer 1 is offset relative to the edge of the acoustic base 2, forming a hidden mounting groove 5 for connecting the panels together.

[0014] Face layer 1 comprises a core 3 made of MDF, gypsum board, HDF, plywood, chipboard, or composite wood material, covered with natural or engineered wood veneer, or finished with a paintable finish. The face layer may also contain microperforations, linear grooves, or milled grooves and may be solid, modular, or feature patterned markings.

[0015] The base of the face layer 1 effectively absorbs some types of sound waves, and also serves as a support plate for the veneer.

[0016] Face layer 1 has the following advantages.

[0017] 1) The base is resistant to warping and deformation, holds its shape perfectly, does not warp over time, and does not crack from changes in temperature and humidity in the room.

[0018] 2) The face layer is made of a solid decorative acoustic panel, ensuring the integrity of the texture and stability of the appearance.

[0019] 3) Easy to care for - regular dry cleaning.

[0020] 4) Various design options are possible, for example, made from pure veneer (a thin layer of wood not covered with anything) - they can be easily treated with decorative oil to suit a specific interior.

[0021] Acoustic base 2 is made of non-woven material and may contain additional perforations or acoustic channels. The back of the acoustic base may contain elements for concealed mounting: grooves, protrusions, holes, adhesive pads, and hook-and-loop elements.

[0022] The non-woven polyester material is made of polyester material including PET felt (such as felt or PET acoustic board) containing 30-90% recycled polyethylene terephthalate and / or polyester felt fabric (such as acoustic felt or noise-reducing acoustic board), in which the thickness of the acoustic base is 3-25mm and the surface density is 300-2000g / m 2 .

[0023] Non-woven material absorbs sound waves, allows the wall to "breathe," and prevents pests from growing. It also provides the necessary flexibility for the layer and, consequently, the panel.

[0024] Non-woven material is made from polyester fiber, which undergoes a special heat treatment and is formed into plates that are similar in appearance to felt, but only in appearance.

[0025] Non-woven material has a number of advantages compared to plywood, HDF and other board materials that are often used as the base for wall acoustic panels:

[0026] 1) Eco-Friendly: Non-woven polyester material is made from polyester fibers and is environmentally safe. It does not contain toxic substances and does not release harmful substances into the environment. It also does not provoke allergies or other problems. Unlike HDF or plywood, it is highly breathable, helping prevent mold and mildew. This makes it suitable for use in residential spaces where a healthy and safe indoor climate is important.

[0027] 2) Enhanced Soundproofing: The non-woven material combined with the base of the first layer has a higher sound absorption capacity (compared to, for example, MDF board alone), making it an ideal choice for improving room acoustics. It perfectly improves soundproofing in living spaces, effectively reducing noise and echoes, and also reduces noise coming from adjacent rooms or the street.

[0028] 3) Light weight: The non-woven material is very light and strong enough, and has a reduced weight compared with rigid base panels, making it easy for one person to install.

[0029] 5) Long service life: Non-woven fabrics, such as those made from PET fibers, are highly durable and moisture-resistant, ensuring a long service life. Polyester fibers do not absorb moisture, exhibit virtually no dimensional change, and do not shrink, ensuring the panel's dimensional stability under any operating conditions.

[0030] Face layer 1 is connected to acoustic base 2 using metal staples 4, PVA glue, PUR glue, acrylic dispersion, or hot melt adhesive. An intermediate layer of non-woven fabric, cardboard, mesh material, or thin fiberboard can be placed between face layer 1 and acoustic base 2.

[0031] Let's look at examples of manufacturing and using wall acoustic panels.

[0032] Example 1 of making wall acoustic panel.

[0033] The solid face layer 1 is manufactured as follows. An MDF board serves as the base for the face layer. A facing material in the form of natural wood veneer is applied to the face of the MDF board. Veneering is performed using hot pressing with an adhesive (such as PUR) and press equipment at elevated temperature and pressure, ensuring a strong and durable bond between the veneer and the MDF board. If necessary, a facing material in the form of veneer is also applied to the back of the MDF board to compensate for internal stresses and increase the geometric stability of the face layer.

[0034] After the production of the face layer 1, it is connected to the acoustic base 2, made of non-woven polyester material in the form of PET felt (e.g., felt), including one with a recycled polyethylene terephthalate content of 30-90%. The connection of the face layer 1 to the acoustic base 2 is carried out mechanically, using metal staples (similar fasteners) installed on the back side of the face layer.

[0035] When connecting the face layer 1 and the acoustic base 2, the face layer 1 is placed with an offset relative to the edge of the acoustic base 2, as a result of which a hidden mounting groove is formed, intended for the subsequent connection of the wall acoustic panels to each other without the formation of visible gaps.

[0036] Example 2 of making wall acoustic panel.

[0037] The solid face layer 1 is manufactured as follows. An MDF board serves as the base for the face layer. A facing material in the form of technological wood veneer (fine line) is applied to the face of the MDF board. Veneering is performed using hot pressing with an adhesive (such as PUR) and press equipment at elevated temperature and pressure, ensuring a strong and durable bond between the veneer and the MDF board. If necessary, a facing material in the form of veneer is also applied to the back side of the MDF board to compensate for internal stresses and increase the geometric stability of the face layer.

[0038] After the production of the face layer 1, it is connected to the acoustic base 2 made of non-woven polyester material polyester felt fabric with the thickness of the acoustic base is 3-25mm and the surface density is 300-2000g / m 2The connection of the front layer 1 with the acoustic base 2 is carried out mechanically, using metal staples (similar fastening elements) installed on the back side of the front layer.

[0039] When connecting the face layer 1 and the acoustic base 2, the face layer 1 is placed with an offset relative to the edge of the acoustic base 2, as a result of which a hidden mounting groove is formed, intended for the subsequent connection of the wall acoustic panels to each other without the formation of visible gaps.

[0040] Example 3 of making wall acoustic panel.

[0041] The solid face layer 1 is manufactured as follows. A plywood board, either solid or perforated, is used as the face layer base. A facing material in the form of natural wood veneer is applied to the face of the plywood, optionally with patterned markings and / or microperforation. Veneering is performed using hot pressing equipment at elevated temperature and pressure, ensuring a secure bond between the veneer and the plywood base. After the veneering process is complete, separating the veneer from the plywood is impossible without damaging the material.

[0042] An intermediate layer made of, for example, non-woven fabric or cardboard is placed between the top layer 1 and the acoustic base 2 to improve adhesion and load distribution.

[0043] Next, the finished face layer 1 is connected to the acoustic base 2, made of non-woven polyester material in the form of a polyester felt cloth, while the thickness of the acoustic base is 3-25 mm, and the surface density is 300-2000 g / m 2 Acoustic base 2 is provided with acoustic channels and a groove-shaped concealed mounting element. The face layer 1 is bonded to acoustic base 2 using adhesive, such as PVA glue or a similar adhesive.

[0044] When connecting the face layer 1 and the acoustic base 2, the face layer 1 is positioned with an offset relative to the edge of the acoustic base 2, forming a hidden mounting groove designed to connect the wall acoustic panels together during installation.

[0045] Example 4 of making wall acoustic panel.

[0046] Take a solid face layer 1, made of composite wood material, pre-treated and painted in a given color

[0047] Next, the face layer 1 is connected to the acoustic base 2, made of non-woven polyester material in the form of PET felt, including one with a recycled polyethylene terephthalate content of 30-90%. The connection of the face layer 1 to the acoustic base 2 is carried out using hot melt adhesive (or another heat-activated adhesive composition).

[0048] When connecting the face layer 1 and the acoustic base 2, the face layer 1 is positioned with an offset relative to the edge of the acoustic base 2 during installation, resulting in the formation of a hidden mounting groove intended for the subsequent connection of the wall acoustic panels to each other without the formation of visible joints.

[0049] Example 5 of making wall acoustic panel.

[0050] Take a solid face layer 1, made of composite wood material, pre-treated for the application of a decorative and protective coating. Apply the decorative and protective coating in the form of a decorative film.

[0051] Next, the face layer 1 is connected to the acoustic base 2, made of non-woven polyester material in the form of PET felt, including one with a recycled polyethylene terephthalate content of 30-90%. The connection of the face layer 1 to the acoustic base 2 is carried out mechanically, using metal staples (similar fasteners) installed on the back side of the face layer.

[0052] When connecting the face layer 1 and the acoustic base 2, the face layer 1 is positioned with an offset relative to the edge of the acoustic base 2 during installation, resulting in the formation of a hidden mounting groove intended for the subsequent connection of the wall acoustic panels to each other without the formation of visible joints.

[0053] Panels manufactured using any of the three examples are assembled using a hidden mounting groove formed by offsetting face layer 1 relative to acoustic base 2, with each subsequent panel sliding under the protruding portion of the previous panel. This eliminates visible joints, ensuring a consistent and even spacing between slats. The hidden groove self-locks the panel during joining. Offsetting the decorative panel relative to the base creates a hidden groove that maintains the correct position of adjacent panels, prevents movement during operation, and stabilizes the geometry of the entire assembled surface. Face layer 1 is secured to the non-woven base (acoustic base 2) over a large area (with adhesive, staples, or a combination of both), eliminating localized stress concentrations, increasing the overall strength of the panel, and improving resistance to bending and torsion.

[0054] The panels fit together and lengthwise, as they are assembled using a template. This always ensures an even spacing between panels and precise longitudinal joints. This makes these panels easy to use in design solutions.

[0055] Installation and maintenance of panels does not require drilling holes for the guides; it is enough to use liquid nails or, in special cases, self-tapping screws, which greatly simplifies the installation process and reduces installation time.

[0056] Also, the participation of a professional is not required during the installation process, in addition, there is no need to be afraid of places for installing sockets, switches, brackets, etc., since you can cut the panels with almost any saw, and the base 2 is cut with an ordinary sharp stationery knife.

[0057] Thus, acoustic wall panels are a versatile and ready-made interior design solution that can transform any room quickly and without renovation. Wall acoustic panels significantly improve acoustics, eliminate reverberation, and create a healthy sound environment in the room. With proper installation, they can achieve Class A sound absorption (EN 11654). The panels are installed quickly, saving time and labor.

[0058] The soundproofing properties of the panels are enhanced by the fact that the face layer 1 and the acoustic base 2 form a single panel after being connected. The base 2 is made of a non-woven material with enhanced sound-absorbing properties (high sound absorption coefficient) and thermal insulation. The panels also feature a hidden mounting groove when connected (the panels are assembled without a gap). This also ensures:

[0059] Reduction of panel weight due to non-woven material and its weight, quick gluing of the panel without guides, which allows installation by one person, as a result, simplification and increased ease of installation;

[0060] increased strength, durability and geometric stability due to dimensional stability, moisture resistance, resistance to biological destruction, the ability to maintain dimensions with changes in temperature and humidity, resistance to fatigue loads and long-term mechanical deformations of the acoustic base 2 connected to the face layer 1. These characteristics also ensure a long service life of the panel and the stability of its dimensions;

[0061] Advanced design capabilities;

[0062] possibility of achieving sound absorption class A (EN 11654);

[0063] perfect (gap-free) joining of panels;

[0064] Alignment of uneven walls due to the flexibility of the panels.

[0065] The combination of face layer 1 (MDF / HDF / plywood / composite) and elastic non-woven base 2 creates structural stability and strength, preventing deformation, twisting, and warping. The use of facing veneer allows for the application of a coating to the back of face layer 1 to compensate for internal stresses, preventing warping, buckling, and changes in panel geometry over time.

[0066] We also consider a significant advantage the panels require no pre-finishing and can even be installed on brickwork, as the flexibility of the acoustic base between the two panels allows for leveling out any differences in the wall. Another undeniable advantage is the fact that the wall behind the panels "breathes," minimizing problems with mold and mildew. The acoustic base also acts as insulation, improving the indoor microclimate and reducing heating costs, especially if the panels are installed on an external wall.
