Description

Technical Field

[0001] This utility model relates to the field of PVC decorative sheet technology, and in particular to a PVC decorative sheet with high scratch resistance. Background Technology

[0002] PVC decorative sheets are made of polyvinyl chloride as the main raw material and are sheet-like panels mainly used for decoration. They are a very versatile panel decoration material, and PVC decorative sheets are often used on the side walls of public corridors with high traffic.

[0003] The basic installation method for PVC decorative panels used on the side walls of high-traffic public corridors involves first applying putty and sanding the surface of the corridor side wall smooth. Next, the frame is fixed to the corridor side wall using expansion bolts. Then, a decorative panel is taken, and a special environmentally friendly strong adhesive is evenly applied to its back. It is then attached to the frame and left to stand for five minutes to allow the internal solvent of the adhesive to evaporate properly, achieving optimal adhesion. Next, it is gently tapped with a rubber mallet to further ensure a firm bond. Finally, rust-proof nails are used to secure the panel, further reinforcing the installation and preventing it from falling off. The rust-proof nails pass through pre-drilled holes on the decorative panel and are then hammered into place to secure them to the frame.

[0004] Currently, existing PVC decorative panels used on the side walls of public corridors with high pedestrian traffic are prone to scratches due to the high volume of people, which greatly reduces their surface scratch resistance.

[0005] Furthermore, existing PVC decorative panels used on the side walls of high-traffic public corridors have pre-drilled nail holes on their panels for later installation of rust-proof nails. When the rust-proof nails are hammered, they pass through the pre-drilled nail holes. Since the rust-proof nails are generally made of stainless steel, they can scratch and abrade the nail holes in the PVC material, greatly reducing the scratch and wear resistance of the decorative panel during installation.

[0006] In addition, the existing PVC decorative panels used on the side walls of public corridors with high pedestrian traffic have a problem where the nail heads protrude after the rust-proof nails are nailed to the panels, which greatly reduces the aesthetic appeal.

[0007] Therefore, we designed a highly scratch-resistant PVC decorative panel for use on the side walls of public corridors with high pedestrian traffic to meet the needs of practical applications. Summary of the Invention

[0008] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a PVC decorative sheet with high scratch resistance.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: Design a PVC decorative sheet with high scratch resistance, including a decorative sheet body, a scratch-resistant and wear-resistant layer and a scratch-resistant column sleeve assembly disposed thereon, wherein the decorative sheet body is provided with a groove countersunk hole assembly, a rust-proof nail body is inserted into the scratch-proof column sleeve assembly, and a protective nail sleeve assembly is fitted onto the rust-proof nail body. The decorative piece body is composed of a plate-shaped decorative piece, and the rust-proof nail body is composed of a nail post and a nail head. The back end face of the nail head is provided with a nail body adhesive layer. The back end of the decorative panel is provided with a horizontal groove and a vertical groove, and the inner wall of the horizontal groove and the vertical groove are provided with a decorative panel adhesive layer.

[0010] In detail, the groove countersunk hole assembly consists of a column sleeve hole and a top cap countersunk groove, and the top cap countersunk groove is an integral hexagonal inner groove.

[0011] In detail, the top cap groove is provided with positioning grooves, and there are two positioning grooves that are symmetrical from left to right.

[0012] In detail, the scratch-resistant and wear-resistant layer is uniformly distributed along the surface of the decorative panel.

[0013] In detail, the scratch-resistant column sleeve assembly consists of a top cap and a protective column sleeve. The top cap is a regular hexagonal structure with countersunk nail holes. The back end face of the top cap and the outer wall of the protective column sleeve are both provided with a column sleeve adhesive layer.

[0014] In detail, the top cap has positioning blocks on its left and right end faces, the protective column sleeve is a cylindrical structure, and the grooved nail hole passes through the protective column sleeve.

[0015] In detail, the protective nail sleeve assembly consists of a nail sleeve and a nail head sleeve groove, and the nail sleeve as a whole has a circular shape.

[0016] In detail, the nail sleeve has a buckle groove, which is a rectangular groove and consists of two symmetrical grooves.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model greatly improves the scratch resistance of the decorative panel surface by setting a scratch-resistant and wear-resistant layer structure on the surface of the decorative panel body, thereby avoiding the situation where the surface of the decorative panel is scratched by objects for a long time due to dense traffic, and improving the scratch resistance and wear resistance of the PVC decorative panel surface used on the side wall of a public corridor with high traffic.

[0018] This utility model improves the scratch and wear resistance of the decorative panel by creating a groove and countersunk hole structure with a scratch-resistant column sleeve on the main body of the decorative panel. When the decorative panel is nailed with rust-proof nails, the metal rust-proof nails are prevented from directly rubbing against the PVC decorative panel, thus avoiding wear.

[0019] This utility model provides a protective nail sleeve structure inside the recessed nail hole. When the rust-proof nail body is nailed onto the decorative panel, the nail sleeve can be squeezed and inserted into the recessed nail hole, thus providing full protection for the nail head and ensuring the flatness of the decorative panel surface, thereby improving the overall aesthetics of the decorative panel surface.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-7 A PVC decorative sheet with high scratch resistance includes a decorative sheet body 1, a scratch-resistant and wear-resistant layer 12 and a scratch-resistant column sleeve 3 disposed thereon, the decorative sheet body 1 is provided with a groove countersunk hole group 2, the scratch-resistant column sleeve 3 is provided with a rust-proof nail body 4, and the rust-proof nail body 4 is provided with a protective nail sleeve group 5. The decorative panel body 1 is composed of a panel decorative panel 11, and the anti-rust nail body 4 is composed of a nail post 41 and a nail head 42. The back end face of the nail head 42 is provided with a nail body adhesive layer 43. The back end of the decorative panel 11 is provided with a horizontal groove 13 and a vertical groove 14. The inner wall of the horizontal groove 13 and the vertical groove 14 are provided with a decorative panel adhesive layer 15. The scratch-resistant column sleeve 3 and the protective nail sleeve 5 described in this patent are both made of aluminum alloy, which is wear-resistant and durable.

[0024] The rust-proof nail body 4 is made entirely of stainless steel, while the decorative piece body 1 is a commonly used PVC decorative piece, which is existing technology.

[0025] The horizontal groove 13 and the vertical groove 14, combined with the decorative piece adhesive layer 15, further improve the bonding stability of the decorative piece body 1.

[0026] It should be further noted that the groove countersunk hole group 2 consists of a column sleeve hole 21 and a top cap countersunk groove 22, and the top cap countersunk groove 22 is an inner groove in the shape of a regular hexagon.

[0027] It should be further explained that the top cap recess 22 is provided with positioning grooves 23. There are two positioning grooves 23 that are symmetrical from left to right. When the top cap 31 is inserted into the top cap recess 22, the positioning block 32 will also be inserted into the positioning groove 23, thus realizing the insertion positioning of the top cap 31.

[0028] It should be further explained that the scratch-resistant and wear-resistant layer 12 is uniformly arranged along the surface of the decorative panel 11. The scratch-resistant and wear-resistant layer 12 is an acrylic hardening coating with high hardness. When the decorative panel 11 is completed, the grease and dust on the surface of the decorative panel 11 are first removed. Then, a special acrylic resin liquid coating is uniformly applied to the surface of the decorative panel 11 through a coating roller. Next, the decorative panel 11 is placed into a curing chamber and fully irradiated by a UV lamp preset in the curing chamber. This activates the photoinitiator in the coating, causing it to decompose and generate highly active free radicals. These free radicals quickly initiate a "chain polymerization reaction" of acrylic resin monomers and oligomers, which are interconnected to form a huge three-dimensional network cross-linked polymer. The coating itself has become a strong network whole, and its molecular chains are entangled and chemically bonded with the pretreated PVC surface molecules, resulting in high hardness, high wear resistance, and scratch resistance.

[0029] It should be further noted that the scratch-resistant column sleeve assembly 3 consists of a top cap 31 and a protective column sleeve 33. The top cap 31 has an overall hexagonal shape and a countersunk nail hole 34. The back end face of the top cap 31 and the outer wall of the protective column sleeve 33 are both provided with a column sleeve adhesive layer 35. The decorative piece adhesive layer 15, the column sleeve adhesive layer 35, and the nail body adhesive layer 43 are all made of special environmentally friendly high-strength neoprene rubber adhesive, which has strong bonding stability and durability.

[0030] It should be further noted that the top cap 31 has positioning blocks 32 on its left and right end faces, the protective column sleeve 33 is a cylindrical structure, the groove nail hole 34 passes through the protective column sleeve 33, so that the nail 41 can pass smoothly through the groove nail hole 34 and be nailed to the keel frame pre-set at the back end (nailing to the keel frame is the existing technology).

[0031] It should be further explained that the protective nail sleeve assembly 5 consists of a nail sleeve 51 and a nail head groove 52. The nail sleeve 51 has a circular shape. The protective nail sleeve assembly 5 is made of highly elastic polyurethane rubber. It is squeezed into the recessed nail hole 34 to achieve a sealing and waterproof effect on the nail head 42. At the same time, the color of the nail sleeve 51 is the same as the surface color of the decorative piece 11 of the board, ensuring aesthetics.

[0032] It should be further explained that the nail sleeve 51 has a retaining groove 53. The retaining groove 53 is a rectangular groove and there are two symmetrical ones. If the protective nail sleeve assembly 5 ages and needs to be replaced, you can take a flathead screwdriver and insert it into the retaining groove 53 to pry the protective nail sleeve assembly 5 out. A new protective nail sleeve assembly 5 can be replaced later, which is very convenient.

[0033] Working method: By setting a scratch-resistant and wear-resistant layer 12 on the surface of the decorative panel 11 of the main body 1, the scratch resistance of the surface of the decorative panel 11 is greatly improved, thereby avoiding the situation where the surface of the decorative panel 11 is scratched by objects for a long time due to dense crowds, and improving the scratch resistance and wear resistance of the PVC decorative panel surface used on the side wall of a public corridor with high crowds.

[0034] The basic installation method is as follows: First, the surface of the side wall of the corridor is plastered and sanded smooth. Then, the keel frame is fixed to the side wall of the corridor with expansion bolts. Next, a decorative panel 11 is taken and an adhesive layer 15 is evenly applied to its back. Then, it is attached to the keel frame and left to stand for five minutes to allow the internal solvent of the adhesive to evaporate properly and achieve the best adhesion. A rubber mallet is then used to gently tap the panel to further ensure a firm bond (this is the existing technology). Next, align the top cap 31 and insert it into the top cap recess 22. At this time, the protective post sleeve 33 will also be inserted into the post sleeve hole 21. Through the preset post sleeve adhesive layer 35, the top cap 31 and the protective post sleeve 33 are firmly bonded to the recessed hole group 2. Then, take a rust-proof nail body 4 and insert it into the recessed nail hole 34. Then, use the preset hammer to strike the nail head 42. After the nail head 42 is completely sunk into the recessed nail hole 34, at the same time, the nail post 41 will also be driven into the preset keel frame, realizing the stable installation of the panel decorative piece 11. In addition, the preset nail body adhesive layer 43 also realizes the firm bonding of the nail head 42 to the inner wall of the recessed nail hole 34, further strengthening the installation stability and preventing it from falling off.

[0035] The above installation process allows the metal nail post 41 to be installed in direct contact with the metal scratch-resistant post sleeve 3, avoiding direct friction between the metal rust-proof nail body 4 and the PVC decorative panel body 1, which would cause abrasions and improve the scratch and wear resistance of the decorative panel body 1 during nailing.

[0036] In addition, after the anti-rust nail body 4 is nailed onto the decorative panel 11, the nail sleeve 51 can be squeezed and inserted into the countersunk nail hole 34 to fully protect the nail head 42, and ensure the flatness of the surface of the decorative panel 11, thereby improving the overall aesthetics of the surface of the decorative panel 11.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
