Description

Technical Field

[0001] This invention relates to the field of flooring stickers, specifically to a PVC sound-absorbing self-adhesive flooring sticker and its manufacturing process. Background Technology

[0002] In the field of modern architectural decoration, flooring is a widely used decorative material. As people's requirements for indoor environments continue to increase, they not only demand that flooring have an aesthetically pleasing appearance, but also place higher demands on its functionality, such as sound absorption, waterproofing, and wear resistance, while also expecting greater ease of installation.

[0003] In terms of installation, traditional flooring tiles present difficulties when laid in special locations such as corners and edges. Because of their fixed shape, interference can easily occur when laying them in corners, requiring cutting and other operations, which not only increases the difficulty of installation but also easily leads to material waste. Furthermore, when splicing multiple tiles, existing splicing methods are often not secure enough, easily resulting in problems such as warping at the joints and uneven gaps, affecting the overall aesthetics and usability. Summary of the Invention

[0004] The purpose of this invention is to provide a PVC sound-absorbing self-adhesive floor sticker and its manufacturing process to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A PVC sound-absorbing self-adhesive floor sticker, comprising

[0007] The flooring tile body has inner grooves on all four sides, and a pull-out block is movably installed inside the inner groove. An adjustment mechanism is provided between the pull-out block and the inner groove.

[0008] Card plate one and card plate two are provided on the outside of the floor sticker body. A positioning mechanism is provided between card plate one and card plate two, and a locking mechanism is provided between card plate one, card plate two and pull block.

[0009] In this invention, the flooring body is composed of a substrate layer, an adhesive layer, a waterproof layer, a wear-resistant layer, and a sound-absorbing cotton layer. The adhesive layer is disposed on the lower end surface of the substrate layer, the waterproof layer is disposed on the upper end surface of the substrate layer, the wear-resistant layer is disposed on the upper end surface of the waterproof layer, and the sound-absorbing cotton layer is disposed between the substrate layer and the waterproof layer.

[0010] In this invention, the flooring body is provided with a backing paper on the lower end surface of the adhesive layer. The backing paper is silicone paper with a thickness of 0.08 to 0.12 mm. The substrate layer is polyvinyl chloride with a thickness of 2 to 3 mm.

[0011] In this invention, the waterproof layer is a polyvinyl alcohol film, and the thickness of the polyvinyl alcohol film is 0.1 to 0.2 mm.

[0012] In this invention, the wear-resistant layer is an alumina ceramic coating, and the thickness of the alumina ceramic coating is 0.1 to 0.3 mm.

[0013] In this invention, the sound-absorbing cotton layer is cross-linked polyethylene foam, and the thickness of the cross-linked polyethylene foam is 3-5 mm.

[0014] In this invention, the adjustment mechanism includes toothed grooves, with a plurality of toothed grooves provided on both sides of the inner groove, toothed blocks that mesh with the toothed grooves provided on both sides of the pull-out block, side grooves provided on all four sides of the floor mat body and at both ends of the inner groove, and a rubber pad layer provided on the side wall of the inner groove away from the toothed grooves.

[0015] In this invention, the positioning mechanism includes a rod and a slot, with the rod and slot respectively provided on the same side of the first and second card plates, and the rod and slot being matched.

[0016] In this invention, the locking mechanism includes a locking head, and several locking heads are arranged side by side below the same side of the locking plate one and the locking plate two. The locking slots that match the locking heads are opened on both sides of the end of the pull block.

[0017] A manufacturing process for a PVC sound-absorbing self-adhesive floor sticker includes the following steps:

[0018] Step 1: Place the cross-linked polyethylene foam on the polyvinyl chloride and bond the two together tightly through a hot-pressing process. The hot-pressing temperature is controlled at 120-150℃, the pressure is 0.5-1.5MPa, and the hot-pressing time is 1-3 minutes.

[0019] Step 2: On the upper surface of the substrate layer with the sound-absorbing cotton layer bonded together, a polyvinyl alcohol film is pasted on using an adhesive process, and a roller is used to press it firmly during the pasting process;

[0020] Step 3: Prepare an alumina ceramic coating on the upper surface of the waterproof layer using plasma spraying technology. First, the surface of the waterproof layer is sandblasted to achieve a surface roughness of 3-5 μm. Then, in the plasma spraying equipment, the alumina powder is heated to a molten state and sprayed onto the surface of the waterproof layer at high speed. The coating thickness is controlled at 0.1-0.3 mm.

[0021] Step 4: Apply glue evenly to the lower end of the substrate layer using a roller glue applicator to form an adhesive layer. The amount of glue applied should be uniform to avoid glue accumulation or insufficient application.

[0022] Step 5: Attach silicone paper to the lower end of the adhesive layer. The silicone paper should be 0.08-0.12mm thick. When attaching, ensure that the silicone paper completely covers the adhesive layer and that the edges are neat.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. During installation, the pull-out blocks in the inner grooves on all four sides of the floor tile body can be pulled out. When pulling out, insert two fingers into the side grooves and tighten them inward. At this time, the end of the pull-out block deforms to one side of the rubber pad layer, and the toothed groove separates from the toothed block. Then the pull-out block can be pulled out. When the floor tile body is laid at the corner of the wall, the pull-out block at the corresponding position can be locked back into the inner groove. This will not cause interference during installation.

[0025] 2. When the pull-out block is pulled out from the inner groove and released, the toothed groove and toothed block re-engage, making the pull-out block fixed inside the inner groove. Then, the first and second clamping plates are positioned and assembled. During assembly, the insert rod and slot between the first and second clamping plates are connected, and then the two floor mats are pressed down from the upper connection point. The clamping heads under the first and second clamping plates will be inserted into the slots at the end of the pull-out block and locked. This makes assembly more convenient.

[0026] 3. The cross-linked polyethylene foam of the present invention serves as a sound-absorbing layer with a thickness of 3-5 mm. It has good sound absorption performance and can absorb noise such as footsteps and furniture movement in the room, reduce the noise level in the room, and improve the comfort of the living or working environment. For example, in places where a quiet environment is required, such as a family bedroom or office, the sound-absorbing layer can effectively reduce noise interference. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1-5 As shown, the present invention provides a technical solution:

[0037] A PVC sound-absorbing self-adhesive floor sticker includes a floor sticker body 1, with an inner groove 2 on each of the four sides of the floor sticker body 1. A pull-out block 3 is movably installed inside the inner groove 2. An adjustment mechanism is provided between the pull-out block 3 and the inner groove 2. The adjustment mechanism includes a toothed groove 12. Several toothed grooves 12 are provided on both sides of the inner groove 2. Toothed blocks 13 that mesh with the toothed grooves 12 are provided on both sides of the pull-out block 3. Side grooves 14 are provided on all four sides of the floor sticker body 1 and at both ends of the inner groove 2. A rubber pad layer 15 is provided on the side wall of the inner groove 2 away from the toothed grooves 12.

[0038] In this embodiment, when the device is being laid, the pull-out blocks 3 in the inner grooves 2 on all four sides of the floor tile body 1 can be pulled out. When pulling them out, two fingers are inserted into the side groove 14 and pulled inward. At this time, the end of the pull-out block 3 deforms to one side of the rubber pad layer 15, and the toothed groove 12 disengages from the toothed block 13. Then the pull-out block 3 can be pulled out. When the floor tile body 1 is laid at the corner of the wall, the pull-out block 3 at the corresponding position can be locked back into the inner groove 2. This way, there will be no interference during the laying process.

[0039] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the first card plate 4 and the second card plate 5 are set on the outside of the floor sticker body 1. A positioning mechanism is set between the first card plate 4 and the second card plate 5. The positioning mechanism includes a rod 16 and a slot 17. The rod 16 and the slot 17 are respectively set on the same side of the first card plate 4 and the second card plate 5. The rod 16 and the slot 17 are matched. A locking mechanism is set between the first card plate 4, the second card plate 5 and the pull block 3. The locking mechanism includes a locking head 18. Several locking heads 18 are arranged side by side below the same side of the first card plate 4 and the second card plate 5. The pull block 3 has a slot 19 that matches the locking head 18 on both sides of its end.

[0040] In this embodiment, when the pull-out block 3 is pulled out from the inner groove 2 and released, the toothed groove 12 and the toothed block 13 re-engage, so that the pull-out block 3 is fixed inside the inner groove 2. Then, the first card plate 4 and the second card plate 5 are positioned and assembled. During assembly, the insert rod 16 and the slot 17 between the first card plate 4 and the second card plate 5 are connected. Then, the two floor tile bodies 1 are pressed down from the upper end connection point. The card heads 18 below the first card plate 4 and the second card plate 5 will be inserted into the card slot 19 at the end of the pull-out block 3 and locked. This makes the assembly more convenient.

[0041] like Figure 5 As shown, the flooring body 1 is composed of a substrate layer 6, an adhesive layer 7, a waterproof layer 8, a wear-resistant layer 9, and a sound-absorbing cotton layer 10. The adhesive layer 7 is disposed on the lower end face of the substrate layer 6, the waterproof layer 8 is disposed on the upper end face of the substrate layer 6, and the wear-resistant layer 9 is disposed on the upper end face of the waterproof layer 8. The sound-absorbing cotton layer 10 is disposed between the substrate layer 6 and the waterproof layer 8. The flooring body 1 is also provided with a backing paper 11 on the lower end face of the adhesive layer 7. The backing paper 11 is silicone paper with a thickness of 0.08-0.12mm. The substrate layer 6 is polyvinyl chloride with a thickness of 2-3mm. The waterproof layer 8 is a polyvinyl alcohol film with a thickness of 0.1-0.2mm. The wear-resistant layer 9 is an alumina ceramic coating with a thickness of 0.1-0.3mm. The sound-absorbing cotton layer 10 is cross-linked polyethylene foam with a thickness of 3-5mm.

[0042] In this embodiment, polyvinyl chloride (PVC) is used as the substrate layer 6. It has good chemical stability and can resist the erosion of various chemicals. Under different environmental conditions, such as humid indoor environments with certain chemical pollution, it can maintain its structural integrity and is not easily corroded or decomposed, thereby ensuring the overall stability and service life of the flooring.

[0043] The presence of adhesive layer 7 allows the floor sticker to be easily adhered to the floor or wall. It firmly adheres the floor sticker to the floor or wall, ensuring that it will not easily lift or shift during use. This is very important for interior decoration, as it can achieve good adhesion whether on a flat tile surface or a slightly uneven cement surface.

[0044] Polyvinyl alcohol film, as a waterproof layer 8, with a thickness of 0.1-0.2mm, can effectively prevent water penetration. In humid environments, such as bathroom entrances, near kitchen sinks, or basements, the waterproof layer can prevent water from seeping into the flooring, avoiding problems such as water absorption and mold growth in the sound-absorbing cotton layer and expansion and deformation of the substrate layer caused by moisture.

[0045] The alumina ceramic coating, as a wear-resistant layer, has high hardness and good wear resistance, with a Mohs hardness of about 9 and a thickness between 0.1 and 0.3 mm. It can withstand a lot of friction from people walking around and furniture being dragged. In high-traffic areas such as shopping malls and office corridors, it can effectively reduce wear on the surface of the flooring and extend the service life of the flooring.

[0046] Cross-linked polyethylene foam, used as the sound-absorbing layer 10, has a thickness of 3-5 mm and exhibits excellent sound absorption properties. It can absorb noise such as footsteps and furniture movement, reducing indoor noise levels and improving the comfort of the living or working environment. For example, in homes, bedrooms, or offices where a quiet environment is required, the sound-absorbing layer can effectively reduce noise interference.

[0047] Silicone paper, with a thickness of 0.08–0.12 mm, serves as the base paper and effectively protects the adhesive layer when the floor sticker is not in use. It prevents the adhesive layer from being contaminated by dust or debris or accidentally stuck during storage and transportation, ensuring that the adhesive layer can perform well when used.

[0048] A manufacturing process for a PVC sound-absorbing self-adhesive floor sticker includes the following steps:

[0049] Step 1: Place the cross-linked polyethylene foam on the polyvinyl chloride and bond the two together tightly through a hot-pressing process. The hot-pressing temperature is controlled at 120-150℃, the pressure is 0.5-1.5MPa, and the hot-pressing time is 1-3 minutes.

[0050] Step 2: On the upper surface of the substrate layer with the sound-absorbing cotton layer bonded together, a polyvinyl alcohol film is pasted on using an adhesive process, and a roller is used to press it firmly during the pasting process;

[0051] Step 3: Prepare an alumina ceramic coating on the upper surface of the waterproof layer using plasma spraying technology. First, the surface of the waterproof layer is sandblasted to achieve a surface roughness of 3-5 μm. Then, in the plasma spraying equipment, the alumina powder is heated to a molten state and sprayed onto the surface of the waterproof layer at high speed. The coating thickness is controlled at 0.1-0.3 mm.

[0052] Step 4: Apply glue evenly to the lower end of the substrate layer using a roller glue applicator to form an adhesive layer. The amount of glue applied should be uniform to avoid glue accumulation or insufficient application.

[0053] Step 5: Attach silicone paper to the lower end of the adhesive layer. The silicone paper should be 0.08-0.12mm thick. When attaching, ensure that the silicone paper completely covers the adhesive layer and that the edges are neat.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
