Abstract
Description
Technical Field
[0001] This utility model relates to the field of flooring technology, and specifically to a mixed-color composite flooring. Background Technology
[0002] Mixed-color flooring is a type of flooring with multiple composite colors on its surface, mainly made of wood-plastic composite material. During the production process, wood-plastic composite material and color masterbatch material are mixed and fed into an extruder. Utilizing the differences in melting point, viscosity, etc., between the wood-plastic composite material and the color masterbatch material, the wood-plastic composite material and the color masterbatch material exhibit different flow states, thereby creating a textured effect in the flooring. For example, patent document with application number CN201821880636.X discloses a wood-look embossed mixed-color wood-plastic composite flooring, including a wood-plastic layer and a mixed-color layer. The mixed-color layer is evenly distributed in the wood-plastic layer and forms intermittent black stripes along the length of the board in the embossed surface. The mixed-color layer is a dispersion layer of black masterbatch formed by the melt flow gradient of PE-based wood-plastic composite material in the wood-plastic layer. The intermittent black stripes are formed by the mixed-color layer on the surface of the wood-plastic layer due to flow differences. However, this type of mixed-color flooring often faces the problem of color masterbatch blending and staining with wood-plastic composite matrix. In addition, usually only one color masterbatch can be used to form a single-color texture effect. If multiple color texture effects are to be formed, further mixing between colors is likely to occur, resulting in unstable product quality. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a mixed-color composite flooring that features a multi-colored texture effect without blending the texture colors with the flooring's matrix, resulting in a clearer color pattern.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A mixed-color composite flooring includes a substrate, on at least one side of which a mixed-color composite layer is formed. The mixed-color composite layer includes a textured layer of a first color, a first adhesive layer of a second color, and a second adhesive layer of a third color. The textured layer includes a base and a plurality of protrusions connected to the base, with grooves formed between adjacent protrusions. Each protrusion includes a first exposed surface formed at an end and a transition surface connected to the first exposed surface and extending toward the groove. The first exposed surfaces of the plurality of protrusions are coplanar with each other. The first adhesive layer covers the transition surface and is connected to the edge of the first exposed surface. A concave curved surface is formed on the outer side of the first adhesive layer. The second adhesive layer covers the middle region of the concave curved surface. The edge region of the concave curved surface not covered by the second adhesive layer forms a second exposed surface. A third exposed surface is formed on the outer side of the second adhesive layer.
[0006] Furthermore, the mixed-color composite flooring also includes a protective lacquer layer, which covers the outside of the mixed-color composite layer and is connected to the first exposed surface, the second exposed surface, and the third exposed surface.
[0007] Furthermore, the thickness of the protective paint layer relative to the first exposed surface is 0.2~0.4 mm.
[0008] Furthermore, the thickness of the first adhesion layer is 0.2~0.5mm.
[0009] Furthermore, the maximum depth of the gully is 0.6~1.0 mm.
[0010] It should be noted that, in this application, the maximum depth of the trench is defined as follows: take any point on the inner wall of the trench, calculate the point-to-plane distance between the point and the plane where the first exposed surface is located, and there exists a point such that the point-to-plane distance is the maximum value, which is the depth of the trench.
[0011] Furthermore, the depth of the trench is at least 1.5 times the thickness of the first adhesion layer.
[0012] Furthermore, the ratio of the maximum depth to the maximum width of the gully is 1:(1~3).
[0013] It should be noted that, in this application, the maximum width of the groove is defined as the distance between the first exposed surfaces of two adjacent protrusions forming the groove. The grooves of this invention are typically formed by embossing, and the actual width of the groove gradually decreases in the depth direction; therefore, the width at its opening is the maximum width.
[0014] In this invention, the groove is formed by embossing, therefore the width of the groove in the depth direction should gradually decrease.
[0015] Furthermore, the texture layer is integrally formed with the substrate.
[0016] Furthermore, the height of the third exposed surface is lower than that of the first exposed surface.
[0017] Furthermore, a height difference of 0.1~0.2mm is formed between the third exposed surface and the first exposed surface.
[0018] The following beneficial effects can be achieved by applying this utility model:
[0019] 1. This utility model achieves a multi-color texture effect by setting texture layers of different colors, a first attachment layer and a second attachment layer. The different colors are independent of each other and there will be no problem of color blending. Moreover, the texture shape is formed by the texture layer, and the first attachment layer and the second attachment layer are colored according to the shape of the texture layer, so there will be no texture deviation between the colors.
[0020] 2. In some embodiments of this utility model, a height difference is formed between the third exposed surface and the first exposed surface, so that there is a change in height between the first exposed surface, the second exposed surface and the third exposed surface, so that different colors present different layered structures, thereby improving the visual effect.

Detailed Implementation
[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example
[0026] Reference Figures 1-3 One embodiment of the present invention provides a color-mixed composite floor, which includes a substrate 1 and a color-mixed composite layer 2 formed on one side of the substrate 1;
[0027] The color-mixed composite layer 2 includes a textured layer 21 with a first color, a first adhesion layer 22 with a second color, and a second adhesion layer 3 with a third color;
[0028] The textured layer includes a base 211 and a plurality of protrusions 212 connected to the base 211. A groove 213 is formed between adjacent protrusions 212. Each protrusion includes a first exposed surface 2121 formed at its end and a transition surface 2122 connected to the first exposed surface 2121 and extending toward the groove 213. Two first exposed surfaces 2121 on adjacent protrusions are connected to each other through the transition surface 2122, and the first exposed surfaces on different protrusions are coplanar with each other. The textured layer and the substrate are an integral structure, formed by physical processing of the surface of the substrate.
[0029] The first adhesion layer 22 covers the transition surface 2122 and is connected to the edge of the first exposed surface 2121. The outer side of the first adhesion layer 22 forms a concave curved surface 221. The second adhesion layer 23 covers the middle region of the concave curved surface 221. The edge region of the concave curved surface 221 that is not covered by the second adhesion layer 23 forms a second exposed surface 222. The outer side of the second adhesion layer forms a third exposed surface 231.
[0030] There is a height difference between the third exposed surface and the first exposed surface, so that the heights of the first exposed surface, the second exposed surface and the third exposed surface decrease sequentially.
[0031] The mixed-color composite flooring provided in this embodiment has a multi-colored texture. This texture is formed by protrusions 212 and grooves 231. The central area of the grooves displays the third color of the second attachment layer 3, while the edge area of the grooves connecting with the protrusions displays the second color of the first attachment layer. The protrusions themselves display the first color of the texture layer. In this structure, the first exposed surface is positioned higher, the third exposed surface is positioned lower, and the second exposed surface extends obliquely between the first and second exposed surfaces. This creates different light and shadow effects in the different color areas of the texture, enhancing the sense of layering in the texture structure. In a preferred embodiment, to protect the texture structure from wear, a protective paint layer 24 can be added to the outside of the mixed-color composite layer, connecting the protective paint layer to the first, second, and third exposed surfaces.
[0032] To better understand this utility model, a molding method of this utility model is also provided, which specifically includes the following steps:
[0033] First, prepare a first material and a second material. The first material is extruded through a main extruder to form a substrate precursor. The second material is applied to one side surface of the substrate precursor through a side extruder to form a first adhesion layer precursor. The substrate precursor and the first adhesion layer precursor together constitute a prototype board. An embossing device is used to emboss the side of the prototype board with the first adhesion layer precursor. At this point, the substrate precursor and the first adhesion layer precursor together form a concave-convex structure. Then, a first grinding device is used to process the concave-convex structure of the prototype board, grinding away the first adhesion layer precursor from the raised portion, exposing the substrate precursor from the raised portion to form the first exposed surface. The first adhesion layer precursor located in the recessed portion is then... The first adhesion layer, formed by the embossing process, is retained and forms a discontinuous first adhesion layer. The outer side of the first adhesion layer forms a concave curved surface. A third material is prepared and applied to the polished surface of the prototype board, filling the concave curved surface. Inevitably, some third material also adheres to the first exposed surface. A second polishing device is then used to remove the third material adhering to the first exposed surface, as well as the portion of the third material filling the concave curved surface that has sufficient contact force with the polishing device. At this point, the third material is only retained in the central region of the concave curved surface. The edge region of the first adhesion layer forms the second exposed surface, and the outer side of the third material forms the third exposed surface. In the above steps, the hardness of the second adhesion layer formed by the third material is lower than that of the substrate formed by the first material and the first adhesion layer formed by the second material. By selecting specific parameters of the polishing device, the substrate and the first adhesion layer can be removed simultaneously.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
