[0020] The present invention is now further described in detail. The embodiments described below are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0021] In order to solve the problem of high preparation cost of skin-feel matte decorative plates in the prior art, the present invention provides a method for preparing a skin-feel matte decorative plate, and the preparation method comprises the following steps: S1: Using UV glue and substrate film as raw materials, UV nanoimprinting technology is used to prepare a film plate a with a matte skin-feel texture; Specifically, through this step, a coating with a matte skin-feel texture is prepared on the surface of the substrate film, wherein the matte skin-feel texture is specifically determined according to the requirements of the decorative board; that is, the film plate a includes a substrate film, and a UV coating arranged on the surface of the substrate film; the UV coating has a matte skin-feel texture.

[0022] S2: Apply a hardening liquid on the surface of the film plate a, and after UV curing, obtain the film plate b; Through this step, a hardening layer is prepared on the surface of the film plate a, specifically, on the UV coating side of the film plate a; that is, the film plate b includes a substrate film, a UV coating, and a hardening layer arranged in sequence.

[0023] This step can be performed as follows: the UV coating side of the film plate a is coated by a coating machine, the required coating liquid is a hardening liquid, and the coating dry thickness is preferably 3-5 μm. After drying in a hot oven, UV curing is performed, and after UV curing, the film plate b is rolled up to obtain the coated surface, and the coated surface is the front side of the film plate b; the UV lamp is a mercury lamp, and the curing energy is greater than 800 mj to ensure the coating appearance quality without stripes and dotted line defects.

[0024] S3: After applying hot-melt pressure-sensitive adhesive on the surface of the decorative plate, the decorative plate and the film plate b are pressed together to obtain a pressed body; In this step, the side of the decorative plate coated with the hot-melt pressure-sensitive adhesive is attached to the side of the hardened layer of the film plate b and then pressed.

[0025] This step can be completed on the corresponding device, see Figure 1 As shown, the film sheet b coil is placed on the unwinding shaft 8, and the film is passed to the reel 11 according to the film passing method shown in the figure. After the machine is running, the decorative board 1 is put in. The decorative surface of the decorative board 1 faces upward, and enters the coating anilox roller 3 along with the conveying roller 4. The glue is applied by the glue roller 2, the anilox roller 3, the gap roller 5 and the backing roller 7. A layer of glue is applied on the decorative surface of the decorative board 1. After the coating, the board enters the infrared box 6. Under the action of infrared radiation, the glue is evenly leveled, the solvent evaporates completely, and enters the bonding section. At this time, the speed of the film sheet b unwound by the unwinding roller 8 is consistent with the speed of the decorative board 1. Under the action of the bonding roller 9, the film sheet b and the decorative board are pressed together, and the glue is bonded to form a whole and move forward.

[0026] The plate can be coated with glue by a coating roller or an anilox roller, with a coating thickness of 10-30 μm. The coating glue is a hot melt pressure sensitive adhesive, which has good adhesion to the hardening liquid, with a 100-grid test of 5B or more. The present invention preferably purchases the hot melt pressure sensitive adhesive from Changzhou Xuntu Chemical Industry, with a grade of UY-151.

[0027] S4: peeling the film plate a from the pressed body to obtain a skin-feel matte decorative plate.

[0028] Specifically, after the pressed body formed by pressing in step S3 enters the next set of laminating rollers, the film sheet a is peeled off from the surface of the sheet under the tension of winding, and the film sheet a is obtained and enters the winding shaft for winding. The film sheet a can be reused; at the same time, see Figure 2 As shown, the hardened layer in the film plate b adheres to the decorative plate under the action of the hot-melt pressure-sensitive adhesive on the decorative plate, and continues to move forward into the collecting plate; due to the peeling process, the hardened layer will replicate the matte skin-feel texture on the UV coating in the film plate a, thereby forming a layer of microstructure on the surface of the decorative plate. These microstructures give the decorative plate super-matte and skin-feel functions, thereby obtaining a super-matte skin-feel plate, that is, a skin-feel matte decorative plate.

[0029] The preparation method of the skin-feel matte decorative plate provided by the present invention has no special performance requirements for the equipment. Mass production can be carried out according to the process route with low equipment investment, which helps to expand production capacity; the film plate a used can be reused 20 to 50 times under normal production conditions, which helps to significantly reduce costs.

[0030] Furthermore, the present invention does not require changes to the original decorative board production line or the original processing parameters, and is very easy to implement.

[0031] Specifically, step S1 in the present invention includes the following steps: S11: coating UV glue on the surface of the substrate film to obtain a glue-coated substrate; The preferred material of the substrate film of the present invention is selected from at least one of PET, PC, and PMMA, and the preferred thickness of the substrate film is in the range of 30 μm-250 μm, and the specific preferred substrate film grade is SH86 (SKC, South Korea) 50 μm, and the width is determined according to the size of the plate.

[0032] S12: using a matte skin-feel mold to roll the surface of the substrate coated with glue, and irradiating it with a UV lamp to obtain a substrate with a matte skin-feel texture; Specifically, the matte skin-feel mold of the present invention is preferably made by engraving with a precision engraving machine and subjected to chemical plating treatment. It is further preferred that a matte additive is added to the chemical plating to achieve an ultra-matte effect on the surface of the plating.

[0033] S13: performing secondary curing on the substrate having a matte skin-feel texture by means of a UV lamp to obtain a film plate a having a matte skin-feel texture; preferably, the UV lamp is a mercury lamp, and the curing energy is greater than 800 mj.

[0034] In order to realize the reuse of the film plate a, the present invention preferably comprises the following components in parts by weight: Initiator A 0.5-2 parts; Active diluent A 20-40 parts; Defoamer A 0.5-1 part; Leveling agent A 0.5-1 part; Acrylate resin A 20-50 parts; 10-15 parts of silicone modified acrylate oligomer.

[0035] The UV glue is a 100% full solid coating, which can be cured instantly under UV light; when used, it can be cured quickly after the first UV irradiation. During the second irradiation, under the action of the high-pressure mercury lamp, the cured paint film will precipitate small silicone molecules, forming a coating with low surface energy on the surface of the paint film, achieving good demolding properties for the hardened layer, so that the hardened layer can be separated from the UV coating under the action of a slight external force, and there is no adhesion between the two coatings. After the hardened layer is separated from the UV coating, there is almost no residue of the hardened layer material on the surface of the UV coating, which is convenient for the reuse of the film plate a.

[0036] Specifically, the preferred initiator A of the present invention is at least one selected from BP, TPOL, 184, 651, 907, and BAPO; the preferred active diluent A is at least one selected from TPGDA, NPGDA, HDDA, TMPTA, DITMPTA, and IBOA; the preferred defoamer A is BYK 1791; the preferred leveling agent A is DOWSIL 204SL; the preferred acrylate resin A is at least one selected from polyurethane acrylate resin and bisphenol A type epoxy acrylate resin; the organosilicon-modified acrylate oligomer is an organosilicon-modified polyurethane acrylate oligomer; the preferred organosilicon-modified acrylate oligomer of the present invention is homemade, and the preferred raw materials thereof include the following components in parts by weight: Polyethylene glycol: 3-6 parts, silicone oil: 10-20 parts, diisocyanate: 5-10 parts, PETA: 1-5 parts, dibutyltin dilaurate: 0.1-0.6 parts.

[0037] In order to facilitate the control of the hardened layer, the present invention preferably includes the following components in parts by weight: 50-60 parts of solvent; 20-30 parts of bisphenol A epoxy acrylate resin; Defoaming agent B 0.5-1 part; Leveling agent B 0.5-1 part; 5-10 parts of monomer; Initiator B 0.5-1 part.

[0038] When the hardening liquid is used, the thickness of the paint film is easy to control and relatively thin due to the addition of solvents, so that during UV curing, ultraviolet rays can penetrate and cure more easily.

[0039] Specifically, the preferred solvent of the present invention is ethyl acetate; the preferred defoamer B is BYK 1791; the preferred leveling agent B is DOWSIL 204SL; the preferred initiator B is selected from at least one of BP, TPOL, 184, 651, 907, and BAPO; and the preferred monomer is selected from at least one of dipentaerythritol pentaacrylate, pentaerythritol triacrylate, and butanediol diacrylate.

[0040] The hardening liquid provided by the present invention, with the addition of a large amount of multifunctional monomers, can cause the paint film to shrink to a certain extent during curing. This shrinkage stress can reduce the adhesion between the hardened layer and the UV coating, making subsequent film stripping easier.

[0041] In specific applications, through the combination of the UV glue and the hardening liquid provided by the present invention, the UV glue has the function of replicating the surface texture of the roller mold. It is a 100% full-solid coating and can be instantly cured under UV light. During use, the hardening liquid is applied to the surface of the cured UV glue by coating. After heating, the solvent in the coating will evaporate, and then it will be thoroughly cured after being irradiated by a UV lamp. After curing, the hardening liquid can be separated from the UV glue under the action of a slight external force, and there is no adhesion between the two coatings. After the hardening liquid is separated from the UV glue, there is almost no residue of hardening liquid on the surface of the UV coating. This facilitates the reuse of the membrane plate a. The hardened layer formed by the hardening liquid remains on the surface of the decorative board, providing special effects for the decorative board, such as super matte, skin feel, fingerprint resistance, acid and alkali resistance, etc. In summary, the preparation method of the skin-feel matte decorative plate provided by the present invention is based on new materials and processes, and realizes the preparation of the skin-feel matte decorative plate under the premise of greatly reducing the preparation cost; and the present invention uses a matte skin-feel mold to prepare a matte film, and uses a UV nano-transfer process, which can achieve gloss control, and is more controllable than excimer. Excimer lamps have a short life and are expensive, while the present invention uses UV mercury lamps, which have a long life and are cheap. Since the present invention uses a hardening liquid as the surface coating of the decorative plate, the surface of the decorative plate can reach a pencil hardness of more than 4H. In the present invention, the application range of the membrane plate b is relatively wide, and different colors and different plates can be modified on the surface to improve their skin feel and super matte properties.

[0042] The decorative board prepared by the preparation method provided by the present invention can achieve a super matte effect, and the minimum gloss can reach 0 degrees; the decorative board of the present invention has a skin feel close to that of real skin, the surface hardness can reach more than 4H, and the surface of the decorative board has other functional characteristics such as anti-pollution, antibacterial and self-cleaning; the preparation method of the decorative board of the present invention has high production efficiency and can be produced continuously; the fixed investment in equipment is small, which is conducive to the rapid realization of mass production and capacity increase (relative to EB, excimer and other curing equipment).

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0082] The decorative panels prepared in the above embodiments and comparative examples were tested for performance, and the testing method was as follows: The peeling condition of film plate a is detected by visual inspection; the number of times that film plate a can be reused is based on the number of times when the hardened layer cannot be peeled off smoothly, or although the hardened layer can be peeled off smoothly, the matte effect of the decorative plate does not meet the requirements; the pencil hardness is tested in accordance with GB / T-17657; the gloss is tested in accordance with GB / T-9754; the skin feel is tested by touch; and the bending cracking is tested by manual bending.

[0083] The test results are shown in Table 1: Table 1 As can be seen from the above table, the preparation method of the skin-feel matte decorative plate provided by each embodiment of the present invention has a simple process, the film plate a can be reused many times, and the cost is low; and the prepared skin-feel matte decorative plate has high hardness and has super matte and skin-feel effects.

[0084] The difference between Comparative Example 1 and Example 1 is that no silicone-modified acrylate oligomer is added to the UV glue, and during the preparation of the skin-feel matte decorative board, the film plate a is not easy to peel off and has poor reusability.

[0085] The difference between Comparative Example 2 and Example 1 is that the amount of silicone-modified acrylate oligomer added to the UV glue is increased, and the appearance of the prepared skin-feel matte decorative board meets the requirements, but the adhesion of the UV coating to the substrate is poor, resulting in a reduced number of reuses of the film plate a.

[0086] The difference between Comparative Example 3 and Example 1 is that the polyurethane acrylate resin in the UV glue is replaced by polyester acrylate resin, and the number of times the film plate a is reused is reduced during the preparation of the skin-feel matte decorative plate.

[0087] The difference between Comparative Example 4 and Example 1 is that the monofunctional monomer IBOA is used to replace the dipentaerythritol pentaacrylate in the hardening solution, and the hardness of the prepared skin-feel matte decorative plate is insufficient and cannot meet the use requirements.

[0088] The difference between Comparative Example 5 and Example 1 is that the amount of dipentaerythritol pentaacrylate added to the hardening solution is increased, and the coating on the curved surface of the prepared skin-feel matte decorative plate is prone to cracking.

[0089] The difference between Comparative Example 6 and Example 1 is that polyester acrylate resin is used instead of bisphenol A epoxy acrylate resin in the hardening liquid, and the hardness of the prepared skin-feel matte decorative plate is insufficient.
