Description

Technical Field

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

[0002] PVC decorative sheets, with their excellent wear resistance, corrosion resistance, rich and diverse colors, and relatively low cost, have been widely used in architectural decoration, furniture manufacturing, and interior decoration. They can simulate the textures and appearances of various natural materials such as wood, stone, and metal, providing a wealth of choices for various decorative scenarios and greatly satisfying people's dual needs for aesthetics and practicality. However, in actual decoration construction, when decorating a large surface area, it is inevitable to splice multiple PVC decorative sheets. Currently, one common splicing method is to overlap the edges of two adjacent decorative sheets. However, this overlapping area often results in noticeable seams, making it difficult to perfectly conceal them. This is because PVC decorative sheets themselves have a certain thickness and hardness; after the edges of two materials overlap, a small step or protrusion will form at the overlapping area. Even after subsequent pressing and trimming, it is difficult to completely eliminate this physical difference. Meanwhile, slight dimensional deviations and texture alignment errors that may exist during the production of different sheets, as well as differences in the skill levels of operators during construction, further exacerbate the noticeability of seams. These exposed seams not only damage the integrity and aesthetics of the overall decorative surface, creating visual flaws and affecting the presentation of the decorative effect, but also, over long-term use, dust and dirt easily accumulate at the seams, making them difficult to clean. They may even warp or crack due to external friction or impact, reducing the lifespan and performance of the PVC decorative sheets and causing considerable inconvenience to users. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a PVC decorative sheet that effectively solves the seam problem during splicing.

[0004] In view of this, the present invention provides a PVC decorative sheet, comprising: The first decorative piece consists of multiple pieces that are spliced ​​together. There is a gap between the two first decorative pieces that are spliced ​​together; The longitudinal inner groove has multiple grooves, which are evenly distributed on the first decorative piece; The second decorative piece is placed in the gap between two adjacent first decorative pieces; The guide is fixed to the rear side of the second decorative piece, and the guide corresponds to and is slidably connected to the longitudinal inner groove.

[0005] In the above technical solution, furthermore, the guide member has an adhesive layer on the surface located in the longitudinal inner groove.

[0006] In any of the above technical solutions, furthermore, both the outer sides of the first decorative piece and the second decorative piece are provided with grooves for splicing the decorative pieces.

[0007] In any of the above technical solutions, the first decorative piece and the second decorative piece further include a base layer, an adhesive layer, a color layer and a coating layer stacked sequentially.

[0008] In any of the above technical solutions, a wear-resistant layer is further provided on the top of the coating layer.

[0009] In any of the above technical solutions, the wear-resistant layer is further made of transparent PVC material and frosted material.

[0010] In any of the above technical solutions, furthermore, the guide is provided with sealing elements on the left and right sides, the sealing elements are located inside the longitudinal inner groove, and the sealing elements are in contact with the inner wall of the longitudinal inner groove.

[0011] The beneficial effects of this utility model are: 1.

[0013] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0014] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0015] Example 1: like Figures 1-3 As shown, this embodiment provides a PVC decorative sheet, including: The first decorative piece 1 has multiple pieces that are spliced ​​together. Gap 2: There is a gap 2 between the two first decorative pieces 1 that are spliced ​​together; The longitudinal inner groove 3 has multiple grooves, which are evenly opened on the first decorative piece 1; The second decorative piece 4 is disposed at the gap 2 between two adjacent first decorative pieces 1; The guide 5 is fixed to the rear side of the second decorative piece 4. The guide 5 corresponds to the longitudinal inner groove 3 and is slidably connected to it.

[0016] In this technical solution, the PVC decorative sheet design primarily addresses the issue of noticeable seams at the overlapping edges of adjacent PVC decorative sheets during splicing. By incorporating a first decorative sheet 1, a gap 2, a longitudinal inner groove 3, a second decorative sheet 4, and a guide 5, the design aims to eliminate visual imperfections caused by physical differences at the splicing points, ensuring the integrity and aesthetics of the overall decorative surface. Simultaneously, it prevents the accumulation of dust and dirt at the seams, reducing edge warping and cracking caused by external forces. This, in turn, improves the service life, performance, and decorative quality of the PVC decorative sheet, enhancing its market competitiveness.

[0017] Working principle: Multiple first decorative pieces 1 are spliced ​​together, creating gaps 2 between adjacent pieces. Second decorative pieces 4 are positioned at these gaps 2 to fill them and conceal the previously noticeable seams. A guide 5 is fixed to the rear of the second decorative piece 4 and corresponds to a longitudinal groove 3 on the first decorative piece 1, forming a sliding connection. This sliding connection allows the second decorative piece 4 to move and adjust along the longitudinal groove 3. During installation or maintenance, the second decorative piece 4 can be slid to better fit the size and shape of the gaps 2, ensuring a tight fit between the second decorative piece 4 and the first decorative pieces 1 on both sides, thus more effectively concealing the gaps 2 and preventing steps or protrusions that affect aesthetics. Furthermore, the filling effect of the second decorative piece 4 on the gaps 2 reduces the possibility of dust and dirt entering the gaps, lowering the difficulty of cleaning. At the same time, the close cooperation between the second decorative piece 4 and the first decorative piece 1 also enhances the structural stability of the splicing point, which can resist the impact of external friction and collision to a certain extent, reduce the occurrence of problems such as warping and cracking, and thus extend the service life of the PVC decorative piece.

[0018] like Figure 2 and Figure 3 As shown, in this embodiment, the guide 5 is provided with an adhesive layer 6 on the surface of the longitudinal inner groove 3.

[0019] In this technical solution, the adhesive layer 6 is provided on the surface of the guide 5 located in the longitudinal inner groove 3, which is a further optimization of the original PVC decorative sheet structure. Its core purpose is to enhance the connection stability and tightness between the second decorative sheet 4 and the first decorative sheet 1. Through the bonding effect of the adhesive layer 6, the second decorative sheet 4 can be prevented from shifting or loosening due to external forces (such as collision, friction, vibration, etc.) during use, ensuring that it always stably fills the gap 2 of the adjacent first decorative sheet 1, thereby maintaining the covering effect of the gap 2 for a long time and maintaining the integrity and aesthetics of the overall decorative surface. At the same time, the adhesive layer 6 can make the second decorative sheet 4 and the longitudinal inner groove 3 of the first decorative sheet 1 fit more tightly, reduce the gap between them, further reduce the possibility of dust and dirt entering, improve the convenience of cleaning, and enhance the structural strength of the splice, delay the occurrence of problems such as edge warping and cracking, and extend the service life of the decorative sheet.

[0020] Working Principle: When installing the second decorative piece 4, the guide 5 is first slidably connected to the longitudinal inner groove 3 on the first decorative piece 1. The position of the second decorative piece 4 is adjusted to precisely align with the gap 2 between adjacent first decorative pieces 1, ensuring complete coverage of the gap 2. Once the second decorative piece 4 is in place, the adhesive layer 6 on the guide 5 will come into close contact with the inner wall of the longitudinal inner groove 3 and undergo a bonding reaction, firmly fixing the guide 5 in the longitudinal inner groove 3, thus ensuring the second decorative piece 4 is stably positioned at the gap 2. The adhesive force of the adhesive layer 6 will counteract any external forces that might cause the second decorative piece 4 to shift, ensuring that the second decorative piece 4 remains tightly fitted to both sides of the first decorative pieces 1, preventing the gap 2 from being exposed again due to the second decorative piece 4 loosening. In addition, the adhesive layer 6 fills the tiny gap between the guide 5 and the longitudinal inner groove 3, forming a sealing barrier, reducing the channels for dust, moisture, etc., to enter the gap 2 and the internal structure. This facilitates daily cleaning and prevents damage to the internal structure due to contamination or corrosion, further improving the overall performance and durability of the PVC decorative piece.

[0021] Example 2: This embodiment provides a PVC decorative sheet, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0022] like Figures 1-3 As shown, in this embodiment, the optimized first decorative piece 1 and the second decorative piece 4 are both provided with grooves 7 on their outer sides for splicing the decorative pieces.

[0023] In this technical solution, grooves 7 are provided on the outer sides of the first decorative piece 1 and the second decorative piece 4 for splicing decorative pieces. This is mainly to further optimize the splicing structure of the PVC decorative pieces, improve the convenience, stability, and overall decorative effect of splicing. The grooves 7 allow for more precise splicing between different decorative pieces, reducing misalignment and deviation during the splicing process, thereby enhancing the overall structural strength and avoiding problems such as warping and loosening caused by unstable splicing. Simultaneously, this groove 7 splicing method allows for a more natural transition at the splicing point, further weakening the visual presence of the seam, maintaining the integrity and aesthetics of the decorative surface, and better meeting the needs of actual decorative scenarios.

[0024] Working Principle: When splicing decorative pieces, the grooves 7 on the outer sides of the first decorative piece 1 and the second decorative piece 4 can interlock with the protruding structures (or other structures matching the grooves 7) on other decorative pieces to be spliced ​​(which may be the first decorative piece 1 or the second decorative piece 4 with the same structure, or other compatible auxiliary decorative pieces). During the splicing process, the grooves 7 serve a positioning and guiding function, allowing operators to quickly align the decorative pieces to be spliced ​​based on the position of the grooves 7, reducing adjustment time and improving construction efficiency. Once splicing is complete, the tight interlocking of the grooves 7 with the matching structures forms a mechanical lock, increasing the connection strength between the decorative pieces and making the overall structure more stable and less prone to relative displacement due to external forces. In addition, this tight interlocking reduces gaps at the splicing points, further reducing the possibility of dust and dirt entering, while making the transition at the splicing points smoother and reducing visual abruptness, thereby improving the overall decorative quality.

[0025] like Figure 4 As shown, in this embodiment, the optimized first decorative piece 1 and the second decorative piece 4 include a base layer 8, an adhesive layer 9, a color layer 10 and a coating layer 11 stacked sequentially.

[0026] In this technical solution, the first decorative piece 1 and the second decorative piece 4 adopt a structural design of sequentially stacked base layer 8, adhesive layer 9, color layer 10, and coating layer 11. The main purpose is to improve the overall performance of the PVC decorative piece from multiple aspects, while taking into account both decorative effect and practical value. Through the synergistic effect of each layer, the structural strength and stability of the decorative piece are enhanced, ensuring that it is not easily deformed or damaged during splicing, installation, and long-term use; the decorative effect is optimized, making the color more uniform and durable, and the coating layer 11 can give the surface a richer texture (such as gloss adjustment, wear-resistant and scratch-resistant properties, etc.); in addition, the adhesive layer 9 can strengthen the bonding force between the layers, avoid delamination, extend the service life of the decorative piece, and better meet the decorative needs in different scenarios.

[0027] Working Principle: The base layer 8 serves as the fundamental support structure for the entire decorative panel. Typically made of PVC, it possesses a certain degree of hardness and toughness, providing a stable adhesion carrier for other layers. It also determines the basic shape and dimensional stability of the decorative panel, ensuring good structural integrity during splicing and reducing gaps caused by deformation. The adhesive layer 9, located between the base layer 8 and the color layer 10, primarily functions to tightly bond the base layer 8 and color layer 10 through its adhesive properties, preventing separation and peeling during use. The bonding strength of the adhesive layer 9 directly affects the overall firmness of the decorative panel, ensuring the synergistic effect of each layer. The color layer 10 is responsible for the decorative appearance of the panel. By adding specific pigments or masterbatches, it gives the panel the desired color and texture (e.g., simulating wood or stone). The uniformity and stability of the color layer 10 determine the aesthetics and durability of the decorative effect, preventing fading and color differences, and ensuring a consistent color across the overall decorative surface after splicing. The coating layer 11 covers the outside of the color layer 10 and is typically made of transparent or semi-transparent materials (e.g., wear-resistant resin, metallic coating). Its working principle mainly utilizes its own physicochemical properties to provide protection for the surface of the decorative piece, such as enhancing the surface's wear resistance and scratch resistance, preventing damage to the color layer 10 caused by friction during daily use. Simultaneously, the coating layer 11 can adjust the surface gloss (matte, glossy, etc.), enhancing the texture, and also provides some waterproofing and stain resistance, reducing stain adhesion and making the surface easier to clean, further ensuring the aesthetics and lifespan of the decorative piece. The layers are tightly bonded together; the base layer 8 provides structural support, the adhesive layer 9 ensures interlayer adhesion, the color layer 10 achieves the decorative effect, and the coating layer 11 provides surface protection, collectively forming the high-performance first decorative piece 1 and second decorative piece 4, laying a solid foundation for the overall decorative quality after splicing. During splicing, because the layered structure of each decorative piece is consistent and its performance is stable, splicing problems caused by differences in material properties are reduced. Combined with the second decorative piece 4 at the gap 2 and the guide component 5, the practicality and aesthetics of the decorative piece are further enhanced.

[0028] like Figure 4 As shown, in this embodiment, the top of the coating layer 11 is provided with a wear-resistant layer 12.

[0029] In this technical solution, a wear-resistant layer 12 is set on top of the coating layer 11 to further enhance the surface protection performance of the PVC decorative sheet. Its core purpose is to improve the wear resistance and service life of the decorative sheet. Although the coating layer 11 itself already has a certain wear resistance, in some high-traffic, high-frequency use scenarios (such as shopping mall floors, furniture countertops, etc.), the surface of the decorative sheet is easily subjected to frequent friction and scratches. The coating layer 11 alone is insufficient to resist these damages in the long term. The addition of the wear-resistant layer 12 can effectively enhance the surface's resistance to friction and scratches, reduce scratches and wear on the surface, thereby maintaining the aesthetics and integrity of the decorative sheet for a long time, reducing maintenance costs, and broadening its application range.

[0030] Working Principle: The wear-resistant layer 12 is located on top of the coating layer 11 and is in direct contact with the external environment. Its working principle mainly relies on its excellent wear resistance. The wear-resistant layer 12 is usually made of high-hardness, high-wear-resistant materials (such as aluminum oxide, special wear-resistant resins, etc.). These materials have stable molecular structures and strong anti-friction capabilities. When the surface of the decorative piece is rubbed or scratched by an object, the wear-resistant layer 12 will bear these external forces first. Due to its high hardness, it can resist the shear force and impact force generated during friction, reducing the wear on the material surface. At the same time, the wear-resistant layer 12 is tightly bonded to the coating layer 11 below, forming a double protective barrier. The coating layer 11 provides a good adhesion base for the wear-resistant layer 12, ensuring that the wear-resistant layer 12 is not easy to fall off; while the wear-resistant layer 12 can protect the coating layer 11 and the underlying color layer 10, base layer 8, and other structures from direct wear, avoiding problems such as color exposure and structural damage caused by surface damage. Furthermore, the presence of the wear-resistant layer 12 does not affect the original gloss adjustment, waterproofing, and stain resistance functions of the coating layer 11. On the contrary, it further enhances the durability of the decorative piece on top of these functions. In daily use, even after long-term friction, the wear-resistant layer 12 can maintain a smooth and flat surface, reducing the formation of scratches and ensuring that the decorative piece always maintains a good appearance, extending its replacement cycle and better meeting the wear resistance requirements of the decorative piece in different scenarios.

[0031] like Figure 4 As shown, in this embodiment, the optimized wear-resistant layer 12 is made of transparent PVC material and frosted material.

[0032] In this technical solution, the wear-resistant layer 12 is made of transparent PVC and frosted material, which further optimizes the practicality and decorative effect of the decorative sheet while ensuring wear resistance. First, the transparent PVC material ensures that the wear-resistant layer 12 does not obscure the appearance of the underlying color layer 10 and coating layer 11, allowing the original color, texture, and gloss of the decorative sheet to be fully presented, maintaining the overall aesthetic appeal. Second, the frosted material increases the friction of the wear-resistant layer 12 surface, improving anti-slip performance, especially suitable for floors, countertops, and other surfaces requiring anti-slip properties, reducing the risk of slipping. Third, combining the advantages of both materials ensures good wear resistance while making the wear-resistant layer 12 more closely conform to the overall material characteristics of the PVC decorative sheet, enhancing the stability of the interlayer bond, avoiding problems such as peeling or delamination due to excessive material differences, and further extending the service life of the decorative sheet.

[0033] Working Principle: From a material properties perspective, transparent PVC itself possesses certain wear resistance and flexibility, along with good chemical stability. It exhibits high compatibility with PVC-related materials such as the base layer 8 and coating layer 11 of the decorative sheet, allowing it to bond tightly to the top of the coating layer 11, forming a transparent protective barrier. Its transparency allows the color and texture of the underlying color layer 10 to be clearly displayed without obscuring or altering the appearance of the decorative sheet, ensuring the integrity of the decorative effect. The frosted material is made by frosting or mixing frosted particles onto the surface of the transparent PVC. The resulting micro-uneven structure increases the friction between the material and the object it contacts. When an object slides on the surface of the wear-resistant layer 12, these uneven structures create resistance, reducing the sliding speed and thus providing an anti-slip effect. Simultaneously, the surface structure of the frosted material disperses the force of friction, resulting in more even wear and reducing localized excessive wear. Combined with the inherent wear resistance of PVC, this further enhances the overall wear resistance of the wear-resistant layer 12.

[0034] In practical use, the transparent PVC material serves as the base of the wear-resistant layer 12, providing primary structural support and wear-resistant protection to ensure that the underlying layers are not damaged. The frosted material, on the other hand, provides a non-slip surface, enhancing safety during use. The two materials work synergistically to ensure both the aesthetics and wear resistance of the decorative sheet, while also enhancing its practicality in various scenarios. This allows the PVC decorative sheet to maintain a good appearance while better adapting to various needs in daily use. Furthermore, because both materials share similar characteristics with the PVC decorative sheet, the shrinkage and expansion of each layer tend to be more consistent under conditions of temperature changes and external forces. This reduces stress concentration caused by material differences, thereby lowering the possibility of cracking or detachment of the wear-resistant layer 12 and ensuring the long-term stable use of the decorative sheet.

[0035] Example 3: This embodiment provides a PVC decorative sheet, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] like Figure 3 As shown, in this embodiment, the guide 5 is optimized with sealing elements 13 on both the left and right sides. The sealing elements 13 are located inside the longitudinal inner groove 3 and are in contact with the inner wall of the longitudinal inner groove 3.

[0037] In this technical solution, sealing elements 13 are provided on both sides of the guide 5, located inside the longitudinal inner groove 3 and fitting against the inner wall of the longitudinal inner groove 3. The main purpose is to further improve the sealing and stability of the PVC decorative piece splicing. The tight fit between the sealing elements 13 and the inner wall of the longitudinal inner groove 3 effectively prevents dust, moisture, and other impurities from entering the connection gap between the guide 5 and the longitudinal inner groove 3, as well as the gap 2 between adjacent first decorative pieces 1, avoiding cleaning difficulties and structural damage caused by impurity accumulation. Simultaneously, the sealing elements 13 enhance the friction and fit between the guide 5 and the longitudinal inner groove 3, preventing unnecessary sliding or shaking of the guide 5 within the longitudinal inner groove 3, ensuring that the second decorative piece 4 stably fills the gap 2, maintaining the stability and aesthetics of the overall decorative structure, and extending the service life of the decorative pieces.

[0038] As the guide 5, carrying the second decorative piece 4, slides and adjusts its position along the longitudinal inner groove 3, the seal 13 moves along with the guide 5, always maintaining tight contact with the inner wall of the longitudinal inner groove 3. From a sealing perspective, the seal 13 possesses a certain degree of elasticity or flexibility (e.g., using materials like rubber or silicone). When it adheres to the inner wall of the longitudinal inner groove 3, it can fill the tiny gaps between the guide 5 and the inner wall through its own deformation, forming a sealing barrier. This barrier can prevent external dust, moisture, and other impurities from entering the connecting structure, avoiding the accumulation of impurities in the gaps, thereby reducing the impact on the sliding performance of the guide 5, reducing cleaning difficulty, and preventing aging and damage to the guide 5 or the longitudinal inner groove 3 caused by moisture erosion. From a stability perspective, the tight fit between the seal 13 and the inner wall of the longitudinal inner groove 3 generates a certain amount of friction. This friction helps to fix the position of the guide 5, preventing it from accidentally sliding due to vibration, minor collisions, or other external forces during daily use. This, in turn, prevents the second decorative piece 4 from deviating from the gap 2, ensuring that the second decorative piece 4 always accurately fills the gap 2, maintaining the aesthetics and structural stability of the joint. Furthermore, the seal 13 also acts as a buffer, reducing direct collisions between the guide 5 and the longitudinal inner groove 3 when the guide 5 is subjected to external impacts, protecting the structural integrity of both and further enhancing the reliability of the PVC decorative piece splicing structure.

[0039] The synergistic effect of the seal 13, guide 5, and longitudinal inner groove 3 significantly enhances the sealing and stability of the connection part without affecting the normal sliding adjustment function of the guide 5, thereby further optimizing the overall performance of the PVC decorative sheet. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
