Description
Technical Field
[0001] This utility model relates to the field of house decoration technology, and more specifically, to a soundproof floor based on EB curing. Background Technology
[0002] Soundproof flooring is a flooring material specifically designed to reduce footsteps and other noise. It is increasingly popular in modern buildings, especially in apartments, office buildings, and spaces requiring a quiet environment. Soundproof flooring not only provides a comfortable feel underfoot but also significantly reduces noise transmission between floors, improving the comfort of living or working. Traditional soundproof flooring often uses rubber, cork, or foam materials as a cushioning layer. While these materials offer some sound absorption, they suffer from high cost, poor environmental performance (containing volatile organic compounds), and insufficient weather resistance. Furthermore, the curing process for traditional polypropylene flooring often relies on hot pressing or UV curing. The former is energy-intensive, and the latter requires the addition of photoinitiators, which may affect material performance and environmental friendliness. Electron beam curing (EB curing technology), as a new environmentally friendly process, can rapidly initiate polymer cross-linking reactions using a high-energy electron beam, eliminating the need for photoinitiators and offering high curing efficiency and low energy consumption. However, it is not yet widely used in the manufacture of polypropylene-based soundproof flooring. Utility Model Content

[0012] In an optional embodiment, the first surface of the polypropylene decorative layer is provided with a wood grain or stone grain pattern.
[0013] Based on the above scheme, the polypropylene decorative layer has a good decorative effect.
[0014] In an optional embodiment, the soundproof floor further includes a second polypropylene soundproof layer, wherein the lower surface of the second polypropylene substrate layer is adhered to the second polypropylene soundproof layer.
[0015] Based on the above solution, the noise reduction effect is good by using two polypropylene sound-absorbing layers together.
[0016] In an optional embodiment, the thickness of the first polypropylene substrate layer is set to 1.0-3.0 mm.

[0019] Based on the above scheme, the porous polypropylene foam layer, as a sound-absorbing layer, can effectively insulate and dampen sound. Furthermore, by controlling the density, thickness, and porosity of the sound-absorbing layer of the first matrix, its sound absorption and insulation performance can be further optimized.
[0020] In an optional embodiment, the thickness of the second polypropylene substrate layer is set to 4.0-9.0 mm.
[0021] Based on the above scheme, the substrate layer of the second substrate has high structural strength, strong load-bearing capacity, and long service life.
[0022] In an optional embodiment, the density of the second polypropylene sound-absorbing layer is set to 0.1-0.5 g / cm³. 3 The thickness is set to 1.0-3.0 mm and the porosity is set to 50%-80%.
[0023] Based on the above scheme, the porous polypropylene foam layer is designed as a sound-absorbing layer, which can effectively insulate sound and reduce vibration. Furthermore, by controlling the density, thickness, and porosity of the sound-absorbing layer of the second matrix, its sound absorption and insulation performance can be further optimized.
[0024] In an optional embodiment, a first groove is provided on at least one side of the first polypropylene sound-absorbing layer; or / and, a second groove is provided on at least one side of the second polypropylene sound-absorbing layer.
[0025] Based on the above solution, when the floor is subjected to pressure, the first polypropylene sound-absorbing layer and the second polypropylene sound-absorbing layer will tend to deform in all directions. Due to the design of the first and second grooves, space can be provided for the deformation of the sound-absorbing layers, avoiding damage from compression, improving the safety of the floor and extending its service life.
[0026] The beneficial effects of this utility model embodiment include, for example:
[0027] In summary, the EB-cured soundproof flooring provided in this embodiment includes an EB-cured layer, a polypropylene decorative layer, a first polypropylene substrate layer, a first polypropylene soundproof layer, and a second polypropylene substrate layer. The EB-cured layer is disposed on the upper surface of the polypropylene decorative layer, the lower surface of the polypropylene decorative layer is bonded to the upper surface of the first polypropylene substrate layer, the lower surface of the first polypropylene substrate layer is bonded to the upper surface of the first polypropylene soundproof layer, and the lower surface of the first polypropylene soundproof layer is bonded to the second polypropylene substrate layer. During preparation, a high-energy electron beam can rapidly initiate the polymer crosslinking reaction, eliminating the need for a photoinitiator. Furthermore, the curing efficiency is high, energy consumption is low, and processing and manufacturing costs are reduced.

[0039] Example
[0040] Please refer to Figure 1 This embodiment provides an EB-cured soundproof floor, which includes an EB-cured layer 100, a polypropylene decorative layer 200, a first polypropylene substrate layer 310, a first polypropylene soundproof layer 320, and a second polypropylene substrate layer 410, wherein:
[0041] An EB curing layer 100 is disposed on the upper surface of the polypropylene decorative layer 200, the lower surface of the polypropylene decorative layer 200 is bonded to the upper surface of the first polypropylene substrate layer 310, the lower surface of the first polypropylene substrate layer 310 is bonded to the upper surface of the first polypropylene sound-absorbing layer 320, and the lower surface of the first polypropylene sound-absorbing layer 320 is bonded to the second polypropylene substrate layer 410.
[0042] As described above, the EB-cured soundproof floor provided in this embodiment has the following advantages:
[0043] During the fabrication of the soundproof floor, a high-energy electron beam can rapidly initiate a polymer cross-linking reaction, eliminating the need for photoinitiators. This process also results in high curing efficiency, low energy consumption, and reduced manufacturing costs. Simultaneously, the combination of the first polypropylene substrate layer 310 and the second polypropylene substrate layer 410 enhances the floor's structural strength, load-bearing capacity, and service life, while also providing better protection for the first polypropylene soundproof layer 320.
[0044] The following embodiments illustrate the details of the EB-based soundproof floor of this application by way of example.
[0045] In this embodiment, optionally, the EB-cured soundproof floor includes an EB-cured layer 100, a polypropylene decorative layer 200, a first substrate 300, and a second substrate 400. The EB-cured layer 100, the polypropylene decorative layer 200, the first substrate 300, and the second substrate 400 are arranged in a sequentially stacked manner, with the second substrate 400 located on the side closest to the ground during use. Correspondingly, the EB-cured layer 100 is located on the top surface.
[0046] Optionally, the EB cured layer 100 can be a polypropylene abrasion layer with a thickness of 0.1-0.8 mm. In flooring or other surface treatment applications, using polypropylene as the abrasion layer effectively improves product durability and extends its service life. Setting the EB cured layer 100 as a polypropylene abrasion layer with a thickness controlled between 0.1-0.8 mm provides good abrasion resistance and physical protection. The thickness of the EB cured layer 100 can be 0.1 mm, 0.45 mm, or 0.8 mm, etc.
[0047] Optionally, the polypropylene decorative layer 200 can be set as a polypropylene film layer, with a thickness of 0.07-0.2 mm. Setting the polypropylene decorative layer 200 as a polypropylene film layer and controlling its thickness between 0.07-0.2 mm can effectively improve the product's aesthetics and durability. For example, the thickness of the polypropylene decorative layer 200 can be 0.07 mm, 0.13 mm, or 0.2 mm, etc.
[0048] Furthermore, wood grain or stone grain patterns can be applied to the first surface of the polypropylene decorative layer 200. The polypropylene decorative layer 200 offers excellent decorative effects. It should be understood that wood grain and stone grain patterns can be applied to the first surface using methods such as printing.
[0049] Please refer to Figure 1 Optionally, the first substrate 300 includes a first polypropylene substrate layer 310 and a first polypropylene sound-absorbing layer 320 stacked together. The surface of the first polypropylene substrate layer 310 has a first recess, the upper surface of the first polypropylene sound-absorbing layer 320 has a first protrusion 321, and the lower surface of the second polypropylene sound-absorbing layer 320 has a second protrusion. The first recess can be inserted into the first protrusion 321. Both the first protrusion 321 and the second protrusion are located in the middle of the first polypropylene sound-absorbing layer 320, and correspondingly, the first recess is located in the middle of the first polypropylene substrate layer 310. In this way, the first recess and the first protrusion 321, when engaged, form a first foolproof structure, ensuring correct assembly of the first polypropylene substrate layer 310 and the first polypropylene sound-absorbing layer 320. The surface of the first polypropylene substrate layer 310 away from the first polypropylene sound-absorbing layer 320 is attached to the second surface of the polypropylene decorative layer 200.
[0050] Furthermore, the first polypropylene substrate layer 310 can be configured as a high-density polypropylene sheet, with a thickness of 1.0-3.0 mm. High-density polypropylene has high strength and rigidity, capable of withstanding large mechanical loads, and setting the thickness of the substrate layer of the first matrix 300 to 1.0-3.0 mm facilitates lightweight and thinner design. In addition, the first polypropylene sound-absorbing layer 320 can be configured as a porous polypropylene foam layer, with a density of 0.4-0.6 g / cm³. 3 The thickness is set to 1.0-2.0 mm and the porosity is set to 30%-60%. The porous polypropylene foam layer, as a sound-absorbing layer, effectively insulates and dampens vibrations. Furthermore, by controlling the density, thickness, and porosity of the sound-absorbing layer in the first substrate 300, its sound absorption and insulation performance can be further optimized.
[0051] Optionally, the second substrate 400 includes a second polypropylene substrate layer 410 and a second polypropylene sound-absorbing layer 420 stacked together. A second recess is provided on the surface of the second polypropylene substrate layer 410, approximately located in the middle of the second polypropylene substrate layer 410. The second recess can be inserted into and engaged with a second protrusion. Thus, the second recess and the second protrusion engage to form a second foolproof structure, thereby preventing misalignment of the first polypropylene substrate layer 310 and the second polypropylene substrate layer 410 and improving assembly quality. Simultaneously, the shape or size of the first recess and the first protrusion 321 is inconsistent with the shape or size of the second recess and the second protrusion; that is, the first recess cannot be inserted into and engaged with the second protrusion, and correspondingly, the first protrusion 321 cannot be inserted into and engaged with the second recess, resulting in a good foolproof effect.
[0052] Furthermore, the second polypropylene substrate layer 410 is configured as a high-density polypropylene board or a micro-foamed polypropylene board, with a thickness of 4.0-9.0 mm. The second polypropylene substrate layer 410 has high structural strength, strong load-bearing capacity, and long service life. The thickness of the second polypropylene substrate layer 410 can be 4.0 mm, 6 mm, or 9.0 mm, etc. The second polypropylene sound-absorbing layer 420 is configured as a porous polypropylene foam layer, with a density of 0.1-0.5 g / cm³. 3 The thickness is set to 1.0-3.0 mm and the porosity is set to 50%-80%. The porous polypropylene foam layer is designed as a sound-absorbing layer, which can effectively insulate sound and reduce vibration. Furthermore, by controlling the density, thickness, and porosity of the second polypropylene sound-absorbing layer 420, its sound absorption and sound insulation performance can be further optimized.
[0053] It should be noted that the thickness of the first substrate 300 is the sum of the thicknesses of the first polypropylene substrate layer 310 and the first polypropylene sound-absorbing layer 320, and the thickness of the second substrate 400 is the sum of the thicknesses of the second polypropylene substrate layer 410 and the second polypropylene sound-absorbing layer 420. The thickness of the first substrate 300 is less than the thickness of the second substrate 400. By combining the two substrates, with the bottom substrate being thicker than the top substrate, the bottom substrate primarily serves a load-bearing function, resulting in higher strength, less susceptibility to damage, and a longer service life. Furthermore, the inconsistent thickness of the two substrates allows for a reduction in the overall thickness of the flooring while still meeting strength and sound-absorbing requirements, thus reducing material consumption and lowering costs.
[0054] In this embodiment, it should be noted that after the multi-layer structure of the soundproof floor is arranged, the surface layer is irradiated and cured by electron beam (with energy of 100-300keV and dose of 5-15kGy) to crosslink the polypropylene molecular chains, thereby improving wear resistance and dimensional stability.
[0055] In addition, both the first polypropylene sound-absorbing layer 320 and the second polypropylene sound-absorbing layer 420 can be produced using supercritical CO foaming technology to form a uniform closed-cell structure and optimize the sound absorption effect.
[0056] Please refer to Figure 2 In other embodiments, optionally, a first groove 321 is provided on at least one side of the first polypropylene sound-absorbing layer 320; or / and, a second groove 421 is provided on at least one side of the second polypropylene sound-absorbing layer 420. When the floor is pressed, the first polypropylene sound-absorbing layer 320 and the second polypropylene sound-absorbing layer 420 tend to deform in all directions. Due to the design of the first groove 321 and the second groove 421, space can be provided for the deformation of the sound-absorbing layers, avoiding damage from compression, improving the safety of the floor and extending its service life.
[0057] For example, in this embodiment, the floor has a first side and a second side. The side of the first polypropylene sound-absorbing layer 320 corresponding to the first side is provided with a first groove 321, and the side of the second polypropylene sound-absorbing layer 420 corresponding to the second side is provided with a second groove 421. That is, the grooves on the first polypropylene sound-absorbing layer 320 and the second polypropylene sound-absorbing layer 420 are arranged opposite to each other. Each sound-absorbing layer not only has an independent deformation space, but can also enhance the sound-absorbing effect by increasing the area of the sound-absorbing layer.
[0058] The EB-cured soundproof floor provided in this embodiment has at least the following advantages:
[0059] Noise reduction: The porous first polypropylene noise reduction layer 320 and the second polypropylene noise reduction layer 420 work together to reduce impact noise by 15-20dB.
[0060] Environmental friendliness: EB curing leaves no solvent residue, the production process has zero VOC emissions, and it has excellent weather resistance and durability.
[0061] Durability: The surface wear resistance rating reaches AC4, increasing service life by more than 30%;
[0062] Lightweight: The overall density is lower than that of traditional PVC soundproof flooring, making it easier to transport and install.
[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
