Description

Technical Field

[0001] The present invention belongs to the technical field of boards such as floors, and particularly relates to a wear-resistant and scratch-resistant board and a manufacturing method thereof. Background Art

[0002] The wear resistance of existing floors such as plastic floors is usually improved by coating a substrate with an ultraviolet curable coating (UV coating) containing alumina powder. However, this method has the following problems: since a certain amount of alumina affects the fluidity and coating uniformity of the UV coating, the amount of alumina added at one time should not be too much; in order to obtain sufficient wear resistance, the general method is to coat in small amounts multiple times, which has a long coating time, a large amount of UV coating used, and high production costs.

[0003] Chinese Patent CN 111644360 A discloses a forming method of a wear-resistant floor, including the following steps: coating an adhesive layer on the printed layer pattern of a substrate; when the adhesive layer is not dry, spreading transparent powder on the surface of the adhesive layer; coating a UV adhesive layer; and embossing when the UV adhesive layer is dry or semi-dry. This process overcomes the above problems of uniformity and repeated coating, but still has some disadvantages. Since the UV adhesive layer is coated after the transparent powder is spread, this treatment method makes the powder unable to be embedded inside the coating layer and mostly exposed on the surface of the coating layer, resulting in a rough surface of the product. Even if the UV adhesive layer is coated again, the problem of surface roughness cannot be completely overcome. In addition, the rough surface also affects the subsequent surface treatment to a certain extent, which limits the use of the board. Summary of the Invention

[0004] The present disclosure aims to solve at least one of the above technical problems in the prior art. Therefore, the present disclosure provides a wear-resistant and scratch-resistant board and a manufacturing method thereof. Through the manufacturing method of the present invention, a wear-resistant layer with a smoother surface can be obtained.

[0005] According to a first aspect of the present disclosure, there is provided a wear-resistant and scratch-resistant board, such as a floor, which sequentially includes a substrate, a printed pattern layer, and a UV wear-resistant layer from bottom to top, wherein wear-resistant and scratch-resistant powder is embedded in the upper surface of the UV wear-resistant layer, and the UV wear-resistant layer preferably has a flat upper surface. It should be understood that the wear-resistant and scratch-resistant powder is preferably concentrated near the upper surface of the UV wear-resistant layer, but preferably does not protrude or expose on the surface of the UV wear-resistant layer and may be located below the surface. Preferably, the upper surface is flat such that the surface has no raised parts and recessed parts, such as micropores, and thus the surface is substantially smooth.

[0006] In some embodiments of the present disclosure, the wear-resistant and scratch-resistant powder is pressed into the UV wear-resistant layer by a thin pressing process such as a diaphragm pressing process.

[0007] In some embodiments of the present disclosure, a transparent wear-resistant layer is further disposed between the printed pattern layer and the UV wear-resistant layer. The transparent wear-resistant layer may be a transparent film, and the material of the transparent wear-resistant layer may be determined according to the material of the substrate. For example, when the substrate comprises polyvinyl chloride (PVC) or is made of polyvinyl chloride (PVC), the transparent wear-resistant layer may comprise PVC or be made of PVC; when the substrate comprises polypropylene (PP) or is made of PP, the transparent wear-resistant layer may comprise PP or be made of PP. However, other combinations are also conceivable, for example, the substrate comprises polyethylene terephthalate (PET), and the transparent wear-resistant layer comprises PET or polyethylene terephthalate glycol (PETG). The transparent wear-resistant layer can improve the scratch resistance of the board.

[0008] The substrate may be provided as a substrate layer. In some embodiments of the present disclosure, the substrate is a single-layer or multi-layer board formed by extrusion or hot pressing. Optionally, a backing layer, such as a balancing layer, may be attached to the substrate or may be part of the substrate. The substrate may comprise one or more of plastics, wood, or inorganic materials, or may be made of any combination thereof.

[0009] The method may include applying a primer to the substrate. In some embodiments of the present disclosure, the printed pattern layer is applied by a method comprising the steps of: applying a plastic white film or white coating to the substrate by printing, transfer printing, spray printing, or digital printing. The plastic white film may be applied to the substrate by lamination or adhesive bonding, or the patterned film may be directly laminated or bonded / combined to the substrate.

[0010] In some embodiments of the present disclosure, the wear-resistant and scratch-resistant powder comprises or is at least one of alumina powder, glass powder, silica powder, or nylon powder. The wear-resistant and scratch-resistant powder may be selected from organic materials or inorganic materials, and the inorganic materials may be selected from, for example, metal oxides or silicates.

[0011] In some embodiments of the present disclosure, the particle size of the wear-resistant and scratch-resistant powder is 500 nm to 20 μm. The size and type of the wear-resistant and scratch-resistant powder may be determined according to the performance requirements of the board. For example, the particle size of the wear-resistant and scratch-resistant powder may be 500 nm to 1 μm, 1 μm to 5 μm, 4 μm to 10 μm, 8 μm to 14 μm, 12 μm to 18 μm, or 15 μm to 20 μm.

[0012] In some embodiments of the present disclosure, the amount of the wear-resistant and scratch-resistant powder is 20 g / m 2 to 80 g / m 2 .

[0013] According to a second aspect of the present invention, there is provided a method for manufacturing a wear-resistant and scratch-resistant board such as a floor, comprising the following steps: applying a printed pattern layer on a substrate; coating a first UV coating on the printed pattern layer; then spreading wear-resistant and scratch-resistant powder on the UV coating; and then performing a film pressing process to press the wear-resistant and scratch-resistant powder into the UV coating to form a UV wear-resistant layer.

[0014] Through the film pressing process, the pressing operation can become more controllable. For example, because the film pressing device for implementing the film pressing process can more easily remove from the UV coating containing powder.

[0015] In some embodiments of the present disclosure, the manufacturing method further includes forming a transparent wear-resistant layer on the printed pattern layer before coating the first UV coating.

[0016] In some embodiments of the present disclosure, the coating amount of the first UV coating is 10 g / m 2 to 120 g / m 2 , for example 10 g / m 2 to 80 g / m 2 or 20 g / m 2 to 80 g / m 2 , preferably 40 g / m 2 to 90 g / m 2 .

[0017] In some embodiments of the present disclosure, the manufacturing method further includes performing a surface coating treatment on the UV wear-resistant layer.

[0018] In some embodiments of the present disclosure, the film pressing process is performed using a film pressing device. Preferably, during the film pressing process, the film pressing device may be internally provided with a release film. Alternatively or additionally, the release film may be fed through the film pressing device by means of a roller, for example. Preferably, the release film is ultraviolet transmissive. In addition, the release film may comprise PET or Teflon TM , for example made of PET or Teflon TM fabric. In some embodiments, the release film may include or may be release paper, or it may include or may be made of silicone / polysiloxane / silicone.

[0019] In some embodiments of the present disclosure, the surface coating treatment includes: coating a second UV coating on the UV wear-resistant layer formed after the film pressing process; and performing a surface matte treatment by an excimer lamp and a curing unit such as a UV lamp. Thus, a second UV coating can be obtained.

[0020] In some embodiments of the present disclosure, the film pressing process may include embossing / debossing.

[0021] According to a third aspect of the present disclosure, there is provided a method for manufacturing a wear-resistant and scratch-resistant plate such as a floor, which sequentially includes a substrate, a printed pattern layer, and a UV wear-resistant layer from bottom to top. The method includes the following steps: applying a printed pattern layer on the substrate; coating a first UV coating on the printed pattern layer, thereby obtaining a UV coating; then spreading wear-resistant and scratch-resistant powder on the UV coating; and then performing a film pressing process to press the wear-resistant and scratch-resistant powder into the UV coating to form a UV wear-resistant layer. Preferably, the film pressing process includes pressing a release film onto the UV coating containing the wear-resistant and scratch-resistant powder.

[0022] Embodiments of the third aspect are largely similar to those of the first and second aspects, and reference is made thereto. In addition, the following embodiments are possible:

[0023] The wear-resistant and scratch-resistant powder may be at least partially embedded, for example, completely embedded in the upper surface of the UV wear-resistant layer. By partially embedding in the upper surface, some powder particles may be partially surrounded by the UV wear-resistant layer and partially open upward. By completely embedding in the upper surface, the powder particles may be completely embedded by the UV wear-resistant layer so that no particles are open upward.

[0024] For example, at least 60%, preferably at least 80% of the powder particles may be completely embedded in the upper surface.

[0025] During the film pressing process, the release film may be arranged in the film pressing device.

[0026] Preferably, during the film pressing process, the release film may be internally arranged on the film pressing device. Alternatively or additionally, the release film may be fed through the film pressing device, for example, by means of a roller.

[0027] The printed pattern layer may be applied by printing, transfer printing, inkjet printing, or digital printing.

[0028] The film pressing process may include embossing so that the UV wear-resistant layer obtains an embossed upper surface. Therefore, the embossing may be performed simultaneously with the film pressing process.

[0029] In some embodiments, substantially the entire upper surface of the UV wear-resistant layer may be subjected to the film pressing process. Therefore, all or substantially all of the powder particles may be pressed into the UV coating.

[0030] The release film may be ultraviolet (UV)-transmissive / enable UV transmission. Throughout the present disclosure, the concept of a UV-transmissive release film includes a release film that is semi-transmissive to ultraviolet light.

[0031] The method may include at least partially curing the UV coating, for example, during a film pressing process. For example, the method may include at least partially curing the UV coating by irradiating the UV coating with UV light through a UV-transmissive release film during the film pressing process. By at least partially curing the UV coating, it is easier to remove the release film from the UV coating containing the powder.

[0032] The method may further include a step of curing the first UV coating. Preferably, when the first UV coating is not fully cured, for example, partially cured, the wear-resistant and scratch-resistant powder is dispersed on the UV coating. The method may further include a step of fully curing the UV coating after performing the film pressing process.

[0033] According to a preferred embodiment of the present disclosure, the present disclosure has at least the following beneficial effects.

[0034] According to the present invention, after applying the UV coating, the wear-resistant and scratch-resistant powder is dispersed or sprayed on the surface of the UV coating to ensure uniform distribution of the powder, and then the wear-resistant and scratch-resistant powder is pressed into the UV coating by a film pressing process. Preferably, thereby avoiding the exposure of the wear-resistant and scratch-resistant powder on the surface, forming a wear-resistant layer having a preferably flat and nearly smooth upper surface, and not affecting subsequent surface treatment. During this process, during the formation of the wear-resistant layer, the UV coating only needs to be applied once, which reduces the usage amount and coating time of the UV coating, thereby reducing the cost. In addition, the wear resistance grade of the manufactured board can reach above AC4, which preferably conforms to the EN 13329-2000 standard.

[0035] According to a fourth aspect of the present disclosure, and more generally, the first UV coating and the UV coating in any one of the first, second, or third aspects may be replaced by a first coating and a coating, such as a first reactive polyurethane (PUR) coating and a PUR coating, respectively. The embodiments of the fourth aspect are largely similar to the embodiments of the first, second, and third aspects, and thus reference is made thereto. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 5 Shows an alternative embodiment of a wear-resistant floor manufactured according to Embodiment 2 of the present invention. Detailed implementation mode

[0042] The concept and the resulting technical effects of the present disclosure are clearly and completely described below with reference to embodiments to fully understand the purpose, features, and effects of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, not all embodiments, and based on the embodiments of the present disclosure, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present disclosure.

[0043] Figure 1 Shows an embodiment of a method (block 20) for manufacturing a wear-resistant and scratch-resistant plate 1 (such as a floor). First, a printed pattern layer 3 is applied to a substrate 2 (block 21), for example, by printing, transfer printing, inkjet printing, or digital printing. Optionally, the application may include applying a primer on the substrate 2, such as a plastic white film 8a or a white coating 8b.

[0044] Thereafter, the printed pattern layer 3 is coated with a first UV coating (block 22). Optionally, before applying the first UV coating, a UV primer coating 6a is applied on the printed pattern layer 3, preferably in an amount of 2 - 15 g / m 2 , more preferably 6 - 10 g / m 2 . The UV primer coating 6a can provide improved adhesion between the first UV coating and the substrate 2. Optionally, the first UV coating is thereafter semi-cured, and one or more additional UV coatings are applied on the first UV coating. The coating amount of the first UV coating optionally including the one or more additional UV coatings can be 10 g / m 2 to 120 g / m 2 , for example 10 g / m 2 to 80 g / m 2 or 20 g / m 2 to 80 g / m 2 , preferably 40 g / m 2 to 90 g / m 2 . Thus, a UV coating 6 is obtained from the first UV coating optionally including the one or more additional UV coatings. Then, the wear-resistant and scratch-resistant powder 5 is scattered on the UV coating 6 (block 23), preferably evenly scattered, and thereafter a film pressing process is performed (block 24) such that the powder 5 is pressed into the UV coating 6 to form a UV wear-resistant layer 4. Therefore, the UV wear-resistant layer 4 includes the powder 5 and the UV coating 6, and optionally the UV primer coating 6a, wherein the UV coating 6 includes the first UV coating and optionally one or more additional UV coatings. In some embodiments, the film pressing process can be performed by Figure 2It is implemented by the film pressing device 10. The substrate 2 including the powder 5 scattered on the UV coating 6 can be fed by means of a roller, a conveyor belt or a similar device and passed through the film pressing device 10. Preferably, the powder 5 is scattered when the first UV coating, which optionally includes the one or more additional UV coatings, is not fully cured, preferably uncured. The powder 5 can include or can be at least one of alumina powder, glass powder, silica and nylon powder. Thus, the powder 5 becomes at least partially embedded, for example completely embedded, in the upper surface 4a of the UV wear-resistant layer, see Figure 3 , 4 and 5.

[0045] In some embodiments, the entire upper surface 4a is subjected to a film pressing process. Thus, substantially all the particles in the powder can be pressed into the UV coating 6. For example, at least 60%, preferably at least 80% of the particles of the powder 5, such as substantially all the particles, can be completely embedded in the upper surface.

[0046] In some embodiments, the film pressing device 10 includes at least one roller 18, 19, for example two rollers. For example, the distance between the rollers 18, 19 and the carrier 13 on which the substrate 2 is disposed can be fixed.

[0047] The substrate 2 containing the powder 5 scattered on the UV coating 6 can be pressed in the pressing area P during the film pressing process by at least one pressing operation (for example two pressing operations), for example by at least one roller 18, 19 (for example two rollers).

[0048] Preferably, the film pressing process includes pressing the release film 11 against the UV coating 6 containing the powder 5. In some embodiments, the release film 11 is UV transmissive, and during the film pressing process, the UV coating 6 can be at least partially cured by irradiating the UV coating 6 with UV light through the UV transmissive release film. For example, such curing can be achieved by Figure 2 the UV curing device 12 in

[0049] During the film pressing process, the release film 11 can be fed through the film pressing device 10, and / or it can be internally disposed in the film pressing device 10. The release film 11 can be fed by at least one roller 18, 19. In addition, during the use of the film pressing device 10, the release film 11 can be disposed between at least one roller 18, 19 and the carrier 13.

[0050] In some embodiments, the surface 17 of the release film 11 configured to face the substrate 2 during use can be substantially smooth, so that the UV wear-resistant layer 4 can obtain a substantially flat upper surface 4a.

[0051] In some embodiments, a transparent wear-resistant layer 7 can be formed on the printed pattern layer 3 before applying the first UV coating, seeFigure 4 .

[0052] The method may further include the step of fully curing the UV coating 6 after spreading the powder 5 and after performing the film pressing process, and the step of fully curing the UV coating 6 is carried out, for example, by the curing device 12 and / or by the curing unit 14 located downstream of the pressing zone P. Alternatively, the coating device 15 can be used to coat a second UV coating on the UV wear-resistant layer 4 formed after the film pressing process, thereby obtaining a second UV coating 6' (block 25), see Figure 2 and 5 . Preferably, the second UV coating 6' is applied in an amount of 5 - 15 g / m 2 , more preferably 8 - 12 g / m 2 . The second UV coating 6' can be cured by the curing unit 14, such as a UV lamp. In some embodiments, a surface coating treatment can be performed on the UV wear-resistant layer 4, for example, by performing a surface matte treatment by the excimer lamp 9 and / or the curing unit 14 (such as a UV lamp) to perform a surface coating treatment on the UV wear-resistant layer 4.

[0053] In the above, any one or all of the first and second UV coatings and the optional one or more additional UV coatings can be acrylic-based UV coatings.

[0054] In some embodiments, the film pressing process includes embossing, such that the UV wear-resistant layer 4 obtains an embossed upper surface 4a. For example, the release film 11 can include a textured surface 17 for providing an embossed surface.

[0055] Example 1

[0056] In this embodiment, a wear-resistant floor 1 was manufactured. See Figure 3 , the wear-resistant floor sequentially includes a substrate 2, a printed pattern layer 3, and a UV wear-resistant layer 4 from bottom to top. Alumina powder 5 is embedded in the upper surface 4a of the UV wear-resistant layer, and the alumina powder is pressed into the UV wear-resistant layer by the film pressing process.

[0057] The specific manufacturing method in this embodiment is as follows.

[0058] Attach / adhere the white film 8a to the PVC substrate 2, spray the pattern on the white film by digital printing to form the printed pattern layer 3, coat the first UV coating on the printed pattern layer with a coating amount of 60 g / m 2 , thereby obtaining the UV coating 6, and then coat it with a coating amount of 80 g / m 2An amount of alumina powder 5 is spread on the UV coating 6, and then it is subjected to a film pressing process by a film pressing device 10 including a PET release film 11. During the film pressing process, the UV coating is cured, and the alumina powder is pressed into the UV coating to obtain a UV wear-resistant layer 4. Finally, a second UV coating (see Figure 5 ) is applied on the upper surface 4a of the UV wear-resistant layer, thereby obtaining a second UV coating 6', and then it is subjected to a surface matting process by a curing unit 14 in the form of an excimer lamp 9 and a UV lamp, thereby obtaining a wear-resistant floor 1. According to the EN 13329-2000 standard, the wear resistance grade of the wear-resistant floor is AC5.

[0059] Example 2

[0060] In this example, a wear-resistant floor 1 is manufactured. See Figure 4 and Figure 5 , the wear-resistant floor sequentially includes a substrate 2, a printed pattern layer 3, a transparent wear-resistant layer 7, and a UV wear-resistant layer 4 from bottom to top. Wear-resistant and scratch-resistant powder 5 is embedded in the upper surface 4a of the UV wear-resistant layer, and the wear-resistant and scratch-resistant powder is pressed into the UV wear-resistant layer by a film pressing process.

[0061] The specific manufacturing method in this example is as follows.

[0062] A white film 8a is attached to the PVC substrate 2, a pattern is sprayed on the white film by digital printing to form a printed pattern layer 3, a PVC transparent wear-resistant layer 7 is first formed on the printed pattern layer, and then a first UV coating is applied on the PVC transparent wear-resistant layer at a coating amount of 40 g / m 2 to obtain a UV coating 6, and then alumina powder 5 is spread on the UV coating 6 at an amount of 20 g / m 2 , and then it is subjected to a film pressing process by a film pressing device 10 including a PET release film 11. During the film pressing process, the UV coating is cured, and the alumina powder is pressed into the UV coating to obtain a UV wear-resistant layer 4. Finally, a second UV coating (see Figure 5 ) is applied on the upper surface 4a of the UV wear-resistant layer, thereby obtaining a second UV coating 6', and then it is subjected to a surface matting process by a curing unit 14 in the form of an excimer lamp 9 and a UV lamp, thereby obtaining a wear-resistant floor 1. According to the EN 13329-2000 standard, the wear resistance grade of the wear-resistant floor is AC4.

[0063] Comparative Example 1

[0064] In this comparative example, a wear-resistant floor is manufactured, which is different from Example 2 in that a second UV coating is directly applied after spreading the alumina powder without the step of film pressing process.

[0065] The specific manufacturing method in this comparative example is as follows.

[0066] Attach the white film to the PVC substrate, spray the pattern on the white film by digital printing to form a printed pattern layer, apply the first UV coating on the printed pattern layer at a coating amount of 40 g / m 2 , then scatter alumina powder on the UV coating in an amount of 20 g / m 2 , then apply the second UV coating on the upper surface of the UV wear-resistant layer, and then perform surface matte treatment on it with an excimer lamp and a UV lamp to obtain a wear-resistant floor. The wear resistance grade of the wear-resistant floor is determined to be AC4, and the surface of the wear-resistant floor is rough, which cannot achieve the expected effect of surface matte treatment.

[0067] The embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the above embodiments, and various changes can also be made within the knowledge scope of those of ordinary skill in the art without departing from the purpose of the present disclosure. For example, it should be understood that the rollers 18 and 19 are exemplary, and the film pressing device 10 may include other types of pressing devices, such as a pressing plate or a conveyor belt. In addition, the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
