Description

Technical Field

[0001] The invention relates to the technical field of hard decorative boards, and in particular to a manufacturing method of an imitation rattan decorative board and the imitation rattan decorative board. Background Art

[0002] As the decoration style close to nature has become more and more popular in recent years, consumers have also put forward the same demand for decorative materials. Solid wood furniture is favored by consumers for its closeness to nature, but the color of pure solid wood will appear monotonous. For this reason, imitation rattan decorative panels have appeared in the prior art. Adding imitation rattan decorative panels to solid wood furniture can achieve a more harmonious visual effect.

[0003] However, the mainstream imitation rattan decorative panels on the market currently have the following problems: in order to show the light-transmitting effect of imitation rattan, these imitation rattan decorative panels are all set as hollow structures. When the hollow structure is used on the cabinet door, mosquitoes and dust can easily enter the interior of the cabinet through the hollow holes, affecting the user experience. In addition, these decorative panels are all produced using the injection molding process. The size of the injection molded product is restricted by the size of the mold. If you want to make the imitation rattan decorative panel too large, you need to make the mold larger accordingly. However, the manufacturing cost of large-sized molds is extremely high, resulting in a high selling price for the product and low economic benefits. This makes the common imitation rattan decorative panels on the market currently have a length and width of less than half a meter, which cannot be used in large-sized decoration needs. The above problems limit the scope of use of existing imitation rattan decorative panels and make them difficult to promote widely. Summary of the invention

[0004] The purpose of the present invention is to provide a method for manufacturing an imitation rattan decorative board, aiming to solve the problem of limited use range of rattan boards in the prior art, and also provide an imitation rattan decorative board produced based on the manufacturing method.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a method for manufacturing an imitation rattan decorative board, which comprises the following steps: S1, selecting a plastic raw material that is hard, translucent and can be rolled at room temperature and feeding it into an extruder, wherein the extruder heats the plastic raw material and then extrude the melt; S2, the melt is rolled into a continuous plate by a rolling press, wherein the continuous plate obtained by rolling comprises a substrate and a rattan-like structure protruding from the surface of the substrate, the rattan-like structure surrounds a plurality of translucent areas, the thickness of the translucent areas is less than the thickness of the rattan-like structure, so that the light transmittance of the rattan-like structure is less than the light transmittance of the light transmittance of the translucent areas; S3, cooling the continuous plate and cutting it to obtain the imitation rattan decorative board.

[0006] Furthermore, the plastic raw material is PET, PC, PMMA, PP, PE, MMA, PS, ABS or PETG.

[0007] Furthermore, the plastic material is a colored plastic material, so that the thicker the imitation rattan decorative board is, the less light transmittance it has.

[0008] The present invention also provides an imitation rattan decorative board, which is made by the above-mentioned manufacturing method, and includes a substrate and a rattan-like structure protruding from the surface of the substrate. The rattan-like structure surrounds a plurality of light-transmitting areas, the thickness of the light-transmitting areas is less than the thickness of the rattan-like structure, and the light-transmitting areas are sealed structures.

[0009] Furthermore, the thickness of the substrate is 0.3-1 mm, the height of the rattan-like structure protruding from the substrate is 0.8-4 mm, and the thickness of the light-transmitting area is consistent with the thickness of the substrate.

[0010] Furthermore, the rattan-like structure forms a plurality of rattan-like nodes, each rattan-like node comprises two transverse bars, two vertical bars, two 45° oblique bars and two 135° oblique bars, and in the circumferential direction, the two 45° oblique bars and the two 135° oblique bars are evenly distributed around the circumference to form a windmill shape, and the end of each 45° oblique bar is connected to the middle of the transverse bar, and the end of each 135° oblique bar is connected to the middle of the vertical bar; the light-transmitting area is enclosed into an octagon; the rattan-like nodes and the light-transmitting area are spaced apart in the transverse and vertical directions of the imitation rattan decorative panel.

[0011] Furthermore, the 45° oblique bars and the 135° oblique bars are both arranged to be high at one end close to the center of the windmill and low at the end, and the transverse bars and the vertical bars are both arranged to be high in the middle and low at both ends, the end of the 45° oblique bar is lower than the middle of the transverse bar, and the end of the 135° oblique bar is lower than the middle of the vertical bar.

[0012] Furthermore, the widths of the transverse strips, the vertical strips, the 45° oblique strips and the 135° oblique strips are equal and are all 2.5-3.5 mm, and the length and width of the light-transmitting area are equal and are all 6-8 mm.

[0013] Furthermore, a plurality of conical grooves sunken downward from the surface of the substrate are arranged in the light-transmitting area.

[0014] Furthermore, the distance between the bottom of the conical groove and the bottom of the substrate is less than 0.15 mm, and 30-60 conical grooves are arranged in each light-transmitting area.

For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0026] The present invention provides a method for manufacturing a rattan-like decorative board, such as Figure 1 As shown, it includes the following steps: S1, selecting a plastic raw material that is hard, translucent and can be rolled at room temperature and putting it into an extruder, and the extruder heats the plastic raw material and then extrude the melt; S2, the melt is rolled into a continuous plate by a rolling press, wherein the continuous plate obtained by rolling includes a substrate and a rattan-like structure protruding from the surface of the substrate, the rattan-like structure surrounds a plurality of translucent areas, the thickness of the translucent area is less than the thickness of the rattan-like structure, so that the light transmittance of the rattan-like structure is less than the light transmittance of the translucent area; S3, the continuous plate is cooled and then cut to obtain an imitation rattan decorative plate.

[0027] Based on the above steps, the manufacturing method of the imitation rattan decorative board can manufacture large-sized imitation rattan decorative boards at a relatively low cost, and the length of the imitation rattan decorative board can be extended infinitely in theory, and can be applied in different scenes, broadening the use scope of the imitation rattan decorative board, and the production cost of the calendering method is much lower than that of the injection molding method, so that the selling price of the imitation rattan decorative board can be much lower than the same type of products produced by injection molding on the market; in addition, the imitation rattan decorative board produced by the calendering method has no holes and has the effect of dust and insect prevention; furthermore, when calendering, the imitation rattan decorative board is calendered into a rattan-like structure with a thicker thickness and a thinner thickness in the light-transmitting area, which can make different areas of the whole imitation rattan decorative board have different light transmittances, so that the whole imitation rattan decorative board shows a layered color difference, and the rattan texture can be highlighted in the absence of holes, which has a better visual effect and plays a good effect on furniture panels and home decoration.

[0028] In this embodiment, the plastic raw material is PET (polyethylene terephthalate), PC (polycarbonate), PMMA (polymethyl methacrylate), PP (polypropylene), PE (polyethylene), MMA (methyl methacrylate), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene copolymer) or PETG (ethylene glycol-modified polyethylene terephthalate), etc. In actual production, any plastic that can be rolled and produced and is hard at room temperature after rolling can be used. Therefore, different plastic raw materials can be selected according to different usage scenarios, price ranges, functions and other requirements to meet different needs.

[0029] In this embodiment, the plastic raw material is a colored plastic raw material, so that the thicker the thickness of the imitation rattan decorative board is, the less light transmittance it has. In actual production, in order to achieve a better simulation effect, the plastic raw material uses a colored plastic raw material, such as natural colors such as green, brown, and yellow, so that the imitation rattan decorative board is more realistic, and when a colored plastic raw material is used, the thickness of the plate will further affect the light transmittance, and the thicker thickness of the rattan-like structure and the thinner thickness of the light-transmitting area can further show the color difference of different areas and further highlight the rattan texture. Of course, the plastic raw material can also be a transparent plastic raw material to meet the use requirements in specific scenarios.

[0030] The present invention also provides a rattan-like decorative board, which is made by the above-mentioned manufacturing method. Figures 2 to 5 As shown, it includes a substrate and a rattan-like structure 1 protruding from the surface of the substrate, the rattan-like structure 1 surrounds a plurality of light-transmitting areas 2, the thickness of the light-transmitting areas 2 is less than the thickness of the rattan-like structure 1, and the light-transmitting areas 2 are sealed structures.

[0031] In this embodiment, the thickness of the substrate is 0.3-1mm, preferably 0.5mm; the height of the rattan-like structure 1 protruding from the substrate is 0.8-4mm, preferably 1mm; the thickness of the light-transmitting area 2 is consistent with the thickness of the substrate. That is, the total thickness of the whole imitation rattan decorative board is 1.5-2mm. After testing, the imitation rattan decorative board in this thickness range meets the decorative use requirements, and because of the thin thickness, small material consumption, low production cost, and high consumer acceptance. Of course, the thickness of the imitation rattan decorative board can also be 2-5mm to meet different use requirements.

[0032] In this embodiment, if Figure 4As shown, the rattan-like structure 1 forms a plurality of rattan-like nodes 11, each rattan-like node 11 includes two transverse strips 111, two vertical strips 112, two 45° oblique strips 113 and two 135° oblique strips 114, and the two 45° oblique strips 113 and the two 135° oblique strips 114 are evenly distributed around the circumference to form a windmill shape, and the ends of each 45° oblique strip 113 are connected to the middle of the transverse strip 111, and the ends of each 135° oblique strip 114 are connected to the middle of the vertical strip 112; the light-transmitting area 2 is surrounded into an octagon; the rattan-like nodes 11 and the light-transmitting area 2 are spaced apart in the transverse and vertical directions of the imitation rattan decorative board. The above-mentioned structure is arranged to form a rattan-like structure 1 that is mutually woven horizontally, vertically and obliquely on the surface of the substrate, and the simulation degree is high. Preferably, the 45° oblique strips 113 and the 135° oblique strips 114 are both set to be high at one end near the center of the windmill and low at the end, the transverse strips 111 and the vertical strips 112 are both set to be high in the middle and low at both ends, the end of the 45° oblique strips 113 is lower than the middle of the transverse strips 111, and the end of the 135° oblique strips 114 is lower than the middle of the vertical strips 112. The actual rattan-like structure 1 is formed by rattans interweaving up and down. For this reason, the present embodiment adopts the setting of the ups and downs of each structural strip, and the morphology of rattans interweaving up and down can be imitated through these ups and downs settings to improve the simulation. Further preferably, the widths of the transverse strips 111, the vertical strips 112, the 45° oblique strips 113 and the 135° oblique strips 114 are equal and are all 2.5-3.5mm, preferably 3mm, and the length and width of the light-transmitting area 2 are equal and are all 6-8mm, preferably 7mm. After testing, the imitation rattan decorative panels based on the above size range have the best simulation effect and excellent visual effect.

[0033] In this embodiment, if Figure 5 As shown, a plurality of conical grooves 21 recessed downward from the surface of the substrate are provided in the light-transmitting area 2. During the rolling production, it is difficult to hollow out the inside of the plate to roll out a hollow structure. Therefore, the light-transmitting area 2 of this kind of imitation rattan decorative board must have materials and needs to be set to be sealed in order to achieve product consistency, that is, the light-transmitting area 2 has material thickness. However, due to the existence of material thickness, it is inevitable to block light. For this reason, the present embodiment sets a conical groove 21 in the light-transmitting area 2. The existence of the conical groove 21 reduces the material contained in the light-transmitting area 2, increases the light transmission of the light-transmitting area 2, and the setting of the conical groove 21 can also improve the light transmission effect; at the same time, the existence of the conical groove 21 can also reduce the amount of plastic raw materials required for rolling the light-transmitting area 2, thereby reducing production costs. Preferably, the spacing between the bottom of the conical groove 21 and the bottom of the substrate is less than 0.15 mm, and 30-60 conical grooves 21 are provided in each light-transmitting area 2. The above structural parameters are the preferred structural parameters after comprehensively considering the light transmission and structural strength.

[0034] In summary, the manufacturing method of the imitation rattan decorative board provided by the present invention and the imitation rattan decorative board produced based on the manufacturing method can solve the problem of limited use scope of rattan boards in the prior art, and have a wide range of use, low production cost, better use effect and visual effect, and have a good effect on furniture panels and home decoration.

[0035] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the present invention.
