Description

Technical Field

[0001] This utility model relates to the field of PVC decorative film technology, and in particular to a sound-insulating and noise-reducing PVC decorative film. Background Technology

[0002] Polyvinyl chloride (PVC) decorative film is widely used for interior wall, furniture, door and window finishing due to its rich colors, diverse patterns, corrosion resistance and low cost.

[0003] The vast majority of PVC decorative film products currently sold on the market are non-flame-retardant products, posing a fire hazard and easily leading to significant loss of life and property.

[0004] An existing patent (publication number: CN215040845U) discloses a flame-retardant PVC decorative film. In this novel flame-retardant PVC decorative film, after a transparent flame-retardant layer is laminated to the surface of the PVC base film layer, a breathable and heat-dissipating layer is laminated to the outer layer of the transparent flame-retardant layer, so that the resulting flame-retardant PVC decorative film has good breathable and heat-dissipating performance, avoiding excessively high internal temperature and reducing the flame-retardant effect.

[0005] To address the aforementioned issues, existing patents offer solutions. While these solutions provide PVC decorative films with good flame-retardant safety, traditional PVC decorative films suffer from insufficient material density and weak sound wave blocking and absorption capabilities. Consequently, they cannot effectively block indoor and outdoor noise (such as talking, footsteps, and traffic noise), failing to meet the demands of modern consumers for a quiet environment.

[0006] Therefore, a sound-insulating and noise-reducing PVC decorative film is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a sound-insulating and noise-reducing PVC decorative film that can solve the problems of insufficient material density, weak sound wave blocking and absorption capacity of existing traditional PVC decorative films, and inability to effectively block indoor and outdoor noise (such as talking, footsteps, and traffic noise), making it difficult to meet the needs of modern consumers for a quiet environment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a sound-insulating and noise-reducing PVC decorative film, comprising a PVC decorative film body, wherein the PVC decorative film body comprises a decorative surface layer, a first damping layer, a sound-insulating and noise-reducing layer, a second damping layer and a backing layer, wherein the decorative surface layer, the first damping layer, the sound-insulating and noise-reducing layer, the second damping layer and the backing layer are sequentially laminated from top to bottom, and the layers are connected by hot pressing.

[0009] The sound insulation and noise reduction layer includes a first sound insulation sub-layer, a sound wave loss sub-layer, and a second sound insulation sub-layer. The sound wave loss sub-layer is bonded between the first sound insulation sub-layer and the second sound insulation sub-layer using environmentally friendly acrylic pressure-sensitive adhesive.

[0010] Preferably, the decorative surface layer is a PVC base film layer with decorative patterns on its surface.

[0011] Preferably, the top of the decorative surface layer is provided with a wear-resistant layer, and the wear-resistant layer is composed of a transparent wear-resistant polyurethane coating.

[0012] Preferably, both the first damping layer and the second damping layer are made of butyl rubber modified asphalt material, and the two layers have the same thickness.

[0013] Preferably, the thickness of both the first damping layer and the second damping layer is 0.3 mm to 0.8 mm.

[0014] Preferably, the backing layer is either a high-density EVA foam layer or a rubber layer.

[0015] Preferably, the lower surface of the backing layer is coated with a pressure-sensitive adhesive layer, and a release paper is placed beneath the pressure-sensitive adhesive layer.

[0016] Preferably, both the first and second sound insulation layers are made of foamed PVC material with a closed microporous structure inside, and the sound wave loss layer is made of polyester fiber cotton.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application employs a combination of double damping and triple sound insulation. The damping layer effectively suppresses the transmission of sound wave vibrations, while the sound insulation and noise reduction layer, through multiple layers of blocking, absorption, and re-blocking, comprehensively weakens sound wave energy and significantly reduces indoor and outdoor noise penetration, creating a quiet and comfortable environment for users.

[0019] 2. The decorative surface layer of this application retains the rich decorative texture of PVC material, and with the wear-resistant coating on top, it not only meets the aesthetic requirements of interior decoration, but also has excellent wear resistance and easy cleaning performance. The setting of backing layer and pressure-sensitive adhesive layer ensures that the decorative film is easy to install and adheres firmly, making it suitable for use in a variety of scenarios.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 The present invention provides the following technical solution:

[0027] A sound-insulating and noise-reducing PVC decorative film includes a PVC decorative film body 1. The PVC decorative film body 1 includes a decorative surface layer 2, a first damping layer 3, a sound-insulating and noise-reducing layer 4, a second damping layer 5, and a backing layer 6. The decorative surface layer 2, the first damping layer 3, the sound-insulating and noise-reducing layer 4, the second damping layer 5, and the backing layer 6 are sequentially laminated from top to bottom, and the layers are connected by hot pressing.

[0028] The sound insulation and noise reduction layer 4 includes a first sound insulation sub-layer 41, a sound wave loss sub-layer 42 and a second sound insulation sub-layer 43. The sound wave loss sub-layer 42 is bonded between the first sound insulation sub-layer 41 and the second sound insulation layer 43 by an environmentally friendly acrylic pressure-sensitive adhesive.

[0029] In this embodiment: the decorative surface layer 2 and the backing layer 6 form a basic barrier, and the first damping layer 3 and the second damping layer 5 act on both sides of the sound insulation and noise reduction layer 4, effectively suppressing the transmission of sound wave vibration and reducing secondary noise generated by resonance. In the sound insulation and noise reduction layer 4, the first sound insulation sub-layer 41 and the second sound insulation sub-layer 43 block the penetration of sound waves through a closed microporous structure, and the sound wave loss sub-layer 42 absorbs residual sound wave energy through a loose fiber structure, forming a double damping and triple sound insulation noise reduction effect, fully covering the blocking and absorption requirements of noise of different frequencies; and each layer is composited sequentially from top to bottom, and the hot-pressing composite process ensures that the interlayer bonding is tight, without bubbles or delamination, thus ensuring the stability of the overall structure of the PVC decorative film body 1.

[0030] Specifically, such as Figure 2 As shown, decorative layer 2 is a PVC base film layer with decorative patterns on its surface.

[0031] Specifically, such as Figure 2As shown, a wear-resistant layer is provided on the top of the decorative surface layer 2, and the wear-resistant layer is composed of a transparent wear-resistant polyurethane coating 7.

[0032] Specifically, such as Figure 2 As shown, the first damping layer 3 and the second damping layer 5 are both made of butyl rubber modified asphalt material, and the two layers have the same thickness.

[0033] Specifically, such as Figure 2 As shown, the thickness of the first damping layer 3 and the second damping layer 5 is both 0.3 mm to 0.8 mm.

[0034] In this embodiment: the decorative surface layer 2 is made of PVC material with decorative patterns. PVC material has the advantages of diverse colors and realistic patterns, which can simulate various decorative effects such as wood grain, stone, and solid colors, adapting to the needs of different interior decoration styles and enhancing the aesthetics of the space. The polyurethane transparent coating has excellent hardness and wear resistance, which can effectively resist daily friction and scratches, avoid wear and tear on the decorative surface layer 2, and extend the service life of the decorative film. Butyl rubber modified asphalt material is used as the first damping layer 3 and the second damping layer 5. Butyl rubber modified asphalt material has excellent damping characteristics, which can effectively absorb sound wave vibration energy, suppress resonance between the membrane and the substrate, and reduce the noise transmission path. The two layers are symmetrically arranged on both sides of the sound insulation and noise reduction layer 4 to form symmetrical damping protection, ensuring a balanced suppression effect on sound wave vibration and further improving the overall sound insulation and noise reduction performance.

[0035] Specifically, such as Figure 2 As shown, the backing layer 6 is either a high-density EVA foam layer or a rubber layer.

[0036] Specifically, such as Figure 4 As shown, the lower surface of the backing layer 6 is coated with a pressure-sensitive adhesive layer 8, and a release paper 9 is placed under the pressure-sensitive adhesive layer 8.

[0037] In this embodiment: the backing layer 6 is composed of a high-density EVA foam layer or a rubber layer. Both the high-density EVA foam layer and the rubber layer have good elasticity and porous structure, which can further absorb sound wave vibration energy and help improve the overall sound insulation and noise reduction effect; with the setting of pressure-sensitive adhesive layer 8 and release paper 9, the release paper 9 can be removed during installation and the paper can be directly pasted without the need to apply additional glue, which simplifies the operation and reduces the difficulty of construction.

[0038] Specifically, such as Figure 3 As shown, the first sound insulation layer 41 and the second sound insulation layer 43 are both made of foamed PVC material, and have a closed microporous structure inside. The sound wave loss layer 42 is made of polyester fiber cotton.

[0039] In this embodiment: the foamed PVC material of the first sound insulation sub-layer 41 and the second sound insulation sub-layer 43 forms a physical barrier through the closed microporous structure, blocking most of the sound waves from penetrating; the sound wave loss sub-layer 42 made of polyester fiber cotton has a loose structure that can fully absorb the residual sound waves that penetrate the micropores, converting the sound wave energy into heat energy for consumption, avoiding reflected noise, and achieving a dual sound insulation effect of blocking and absorption.

[0040] Working principle: When using the PVC decorative film body 1, peel off part of the release paper 9 from the end of the PVC decorative film body 1 to expose the pressure-sensitive adhesive layer 8. Align the end of the exposed pressure-sensitive adhesive layer 8 with the corresponding position on the surface to be decorated, and gently press it to initially adhere it, ensuring that the texture direction of the film is consistent with the design requirements, without any offset or skewing. While slowly peeling off the remaining release paper 9, use a soft scraper to scrape and press evenly from the adhered end to the other end at the same speed. The scraping and pressing direction is consistent with the film's adhesion direction to expel air between the film and the installation surface, ensuring a tight adhesion of the film. Bubbles and hollow areas are eliminated. In daily use, the wear-resistant layer of the decorative surface layer 2 can resist slight friction and scratches, preventing damage to the decorative surface layer 2. When external noise (such as traffic noise, footsteps, and voices) acts on the membrane, the decorative surface layer 2 and the backing layer 6 first block some sound waves. The first damping layer 3 and the second damping layer 5 absorb the vibration energy of the sound waves and suppress resonance. The first sound insulation sub-layer 41 and the second sound insulation sub-layer 43 block the penetration of sound waves through sealed micropores. The sound wave loss sub-layer 42 absorbs the residual sound waves, ultimately achieving efficient sound insulation and noise reduction, creating a quiet environment.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
