Description

Technical Field

[0001] This application relates to the field of architectural decoration technology, and in particular to a processing method for simulated wood grain, simulated wood grain boards, and intelligent equipment. Background Technology

[0002] As living standards improve, people's demand for aesthetic decoration is increasing. Traditional wood products are loved for their exquisite patterns, but due to the characteristics of wood materials, their performance is difficult to meet the requirements of actual use. Wood products are difficult to be widely used in various decorative modules. Therefore, the simulated wood grain process for materials such as plastic, metal, and glass is becoming increasingly important. However, the traditional simulated wood grain process has a rough effect, is not realistic enough, has low production efficiency, and the pattern is irregular in mass production, making it difficult to quantify.

[0003] For example, the technical solution in patent document CN201910138341.8 involves first heating a thermoplastic skin to its softening point; then obtaining a textured thermoplastic skin through roll forming; finally, obtaining an automotive interior trim skin through vacuum forming; and then sequentially adding the skin, fiberglass, and PU foam material into a mold for composite reinforcement molding to obtain an automotive interior trim with textured grooves; finally, transferring the wood grain pattern onto the surface of the automotive interior trim using water transfer printing. This process has low construction efficiency, many steps, high water transfer printing operation costs, and the final product exhibits an irregular pattern, making mass production impossible.

[0004] For example, the technical solution in the patent document with patent application number CN201511007734.3 and patent name "A Manufacturing Method of Imitation Wood Grain Composite Board" uses a PVC foam layer as the substrate, uses a steel roller engraved with imitation wood grain to imprint the imitation wood grain onto the PVC foam layer, and then sprays a protective paint layer; the simulated wood grain texture obtained by this process is monotonous, the materials are relatively limited, and the actual construction effect is relatively rough.

[0005] For example, the technical solution in patent document CN202210871166.5, entitled "A Processing Technology for Imitation Wood Grain Aluminum Panels for Decoration," achieves the simulated wood grain effect by spraying a primer and topcoat, then applying a film, coloring the film layer, and manually brushing on imitation wood grain paint. This process is complex, involves many steps, and relies on manual brushing of the wood grain pattern, resulting in low simulation accuracy and low product mass production efficiency.

Detailed Implementation

[0029] As used in this article: "Prepared from" is synonymous with "comprising". The terms "comprising", "including", "having", "containing", or any other variations thereof as used herein are intended to cover non-exclusive inclusion. For example, a composition, step, method, article, or apparatus that includes the listed elements is not necessarily limited to those elements, but may include other elements not expressly listed or elements inherent to such composition, step, method, article, or apparatus.

[0030] The conjunction "composed of..." excludes any unspecified elements, steps, or components. If used in a claim, this phrase makes the claim closed, excluding materials other than those described, except for associated conventional impurities. When the phrase "composed of..." appears in a clause of the body of a claim rather than immediately following it, it limits only the elements described in that clause; other elements are not excluded from the claim as a whole.

[0031] When a quantity, concentration, or other value or parameter is expressed as a range, a preferred range, or a range defined by a series of upper and lower preferred values, this should be understood as specifically disclosing all ranges formed by any pair of any upper or preferred value with any lower or preferred value, regardless of whether the range is disclosed individually. For example, when the range “1–5” is disclosed, the described range should be interpreted as including ranges “1–4”, “1–3”, “1–2”, “1–2 and 4–5”, “1–3 and 5”, etc. When numerical ranges are described herein, unless otherwise stated, the range is intended to include its endpoints and all integers and fractions within that range.

[0032] In these embodiments, unless otherwise specified, the portions and percentages are all by weight.

[0033] "Parts by mass" refers to the basic unit of measurement that expresses the mass ratio of multiple components. One part can represent any unit mass, such as 1g or 2.689g. If we say that component A has "a" parts by mass and component B has "b" parts by mass, it means the ratio of the mass of component A to the mass of component B is a:b. Alternatively, it can mean that the mass of component A is aK and the mass of component B is bK (where K is any number representing a multiplier). It is important to understand that, unlike parts by mass, the sum of the mass parts of all components is not limited to 100 parts.

[0034] "And / or" is used to indicate that one or both of the described situations may occur, for example, A and / or B includes (A and B) and (A or B).

[0035] The implementation schemes of this application will be described in detail below with reference to specific embodiments. However, those skilled in the art will understand that the following embodiments are only for illustrating this application and should not be regarded as limiting the scope of this application. Unless otherwise specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments used without specified manufacturers are all conventional products that can be purchased commercially.

[0036] Example 1 Place the ceramic slab that needs to be simulated wood grain on a fixed hanger with the flat surface facing outwards and kept at the same level. Put the ceramic slab into an ultrasonic cleaning tank containing 15% ethylenediamine oleate, 12% C13 isopropanol amide, 2% emulsifier and the balance water. Ultrasonic cleaning is performed at 55℃ for 5 minutes. After ultrasonic cleaning, rinse with pure water 4 times.

[0037] Place the ceramic slab in the laser engraving machine's work area. The machine uses a 100W power setting and a 1500mm / s engraving speed to laser-engrave irregular wood grain texture lines with a depth of 0.01~1mm on the surface, making the wood grain texture more refined and producing a distinct tactile feel. Clean the ceramic slab surface 3~5 times with 75% industrial alcohol, following the engraving direction, to remove stains. Apply air spray to the ceramic slab surface using a 0.8mm nozzle; the air pressure supplied to the spray gun is 0.5Mpa; the distance between the nozzle and the surface being sprayed is 25cm. Spray an adhesion promoter (8% organosilane, balance isopropanol), and let it stand for 15 minutes to prevent poor adhesion during subsequent coloring.

[0038] After applying the adhesion promoter, the ceramic plate is laid flat on the UV 3D printing machine platform. Once positioned, the 3D UV printing equipment is started to print the 3D wood grain pattern and color, which has been processed by the image software, in layers. White ink is pre-printed to a height of 0.01~0.5mm to create a three-dimensional wood grain effect. Then, 1~7 layers of colored paint are printed on the pattern to form a three-dimensional and layered wood grain texture.

[0039] Finally, a layer of UV coating is applied by air spraying to protect against wear during long-term use. The nozzle diameter is 1.2mm; the air pressure supplied to the spray gun is 0.5MPa; the distance between the nozzle and the surface being sprayed is 25cm. A layer of semi-matte UV coating is then applied for protection. This UV coating formulation consists of 40% UV resin, 10% TPGDA, 0.8% additives (0.5% BYK333 + 0.3% BYK016), 6% photoinitiator Esacure kip 100f, and the balance ethyl acetate. After spraying, the coating is baked in a UV lamp box for 15 minutes.

[0040] The actual photos of the ceramic slab before (left) and after (right) construction in Example 1 are shown below. Figure 1 As shown, it can be seen that after adopting the simulated wood grain preparation method of this application, a three-dimensional simulated wood grain can be generated on a white ceramic plate, and the simulation effect is almost the same as that of real wood.

[0041] Example 2 Place the metal plate that needs to be simulated wood grain on the fixed hanger with the flat surface facing outwards and kept on the same horizontal plane. Put the metal plate into an ultrasonic cleaning tank containing 15% ethylenediamine oleate, 12% C13 isopropanol amide, 2% emulsifier and the balance water. Ultrasonic cleaning is performed at 65℃ for 10 minutes. After ultrasonic cleaning, rinse with pure water 5 times.

[0042] Place the metal plate in the laser engraving machine's work area. The machine uses a 120W power setting and an engraving speed of 1800mm / s to laser engrave irregular wood grain texture lines with a depth of 0.01~1mm on the material surface, making the wood grain texture more refined and producing a distinct tactile feel. Clean the metal plate surface 3~5 times with 75% industrial alcohol in the engraving direction to remove stains. Apply air spray to the metal plate surface using a 1.0mm nozzle; the air pressure supplied to the spray gun is 0.6Mpa; the distance between the nozzle and the sprayed surface is 30cm. Spray an adhesion promoter (6% organosilane, balance isopropanol), and let it stand for 15 minutes to prevent poor adhesion for subsequent coloring.

[0043] After the adhesion promoter is sprayed, the metal plate is laid flat on the UV 3D printing machine platform, positioned, and the 3D UV printing equipment is started to print the 3D wood grain pattern and color processed by the image software in layers. White ink texture is pre-printed and deposited to a height of 0.01~0.5mm to create a three-dimensional wood grain texture effect. Then, 1~7 layers of color paint are printed on the pattern to form a three-dimensional and layered wood grain texture appearance.

[0044] Finally, a layer of UV coating is applied by air spraying to protect against wear during long-term use. The nozzle diameter is 1.4mm; the air pressure supplied to the spray gun is 0.6MPa; the distance between the nozzle and the surface being sprayed is 30cm. A layer of semi-matte UV coating is then applied for protection. This UV coating formulation consists of 45% UV resin, 12% TPGDA, 1% additives (0.6% BYK333 + 0.4% BYK016), 8% photoinitiator Esacure kip 100f, and the balance being ethyl acetate and isopropanol. After spraying, the coating is baked in a UV lamp box for 20 minutes.

[0045] The actual photos of the metal plate before (left) and after (right) construction in Example 2 are shown below. Figure 2 As shown, it can be seen that after adopting the simulated wood grain preparation method of this application, a three-dimensional simulated wood grain can be generated on a black metal plate, and the simulation effect is almost the same as that of real wood.

[0046] Example 3 Place the plastic board to be produced with simulated wood grain on a fixed hanger with the flat outer surface facing outwards and kept at the same level. Put the plastic board into an ultrasonic cleaning tank containing 15% ethylenediamine oleate, 12% C13 isopropanol amide, 2% emulsifier and the balance water. Ultrasonic cleaning is performed at 50℃ for 3 minutes. After ultrasonic cleaning, rinse with pure water 3 times.

[0047] Place the plastic sheet in the laser engraving machine's work area. The machine uses a 60W power setting and a 1000mm / s engraving speed to laser-engrave irregular wood grain texture lines with a depth of 0.01~1mm on the surface, making the wood grain texture more refined and producing a distinct tactile feel. Clean the plastic sheet surface 3~5 times with 75% industrial alcohol, following the engraving direction, to remove stains. Apply an adhesion promoter (5% organosilane, balance isopropanol) to the plastic sheet surface using air spraying at a nozzle diameter of 0.8mm and an air pressure of 0.5Mpa. Maintain a nozzle distance of 25cm from the surface. Let it stand for 15 minutes to prevent poor adhesion during subsequent coloring.

[0048] After applying the adhesion promoter, the plastic board is laid flat on the UV 3D printing machine platform and positioned. The 3D UV printing equipment is then started to print the 3D wood grain pattern and color, which has been processed by the image software, in layers. White ink is pre-printed to a height of 0.01~0.5mm to create a three-dimensional wood grain effect. Then, 1~7 layers of colored paint are printed on the pattern to form a three-dimensional and layered wood grain texture.

[0049] Finally, a layer of UV coating is applied by air spraying to protect against wear during long-term use. The nozzle diameter is 1.2mm; the air pressure supplied to the spray gun is 0.5MPa; the distance between the nozzle and the surface being sprayed is 25cm.

[0051] Example 4 Place the glass plate for simulated wood grain production on a fixed hanger with the flat outer surface facing outwards and kept at the same level. Put the glass plate into an ultrasonic cleaning tank containing 15% ethylenediamine oleate, 12% C13 isopropanol amide, 2% emulsifier and the balance water. Ultrasonic cleaning is performed at 55℃ for 5 minutes. After ultrasonic cleaning, rinse with pure water 4 times.

[0052] Place the glass plate in the laser engraving machine's work area. The machine uses a 100W power setting and a 1500mm / s engraving speed to laser-engrave irregular wood grain texture lines with a depth of 0.01~1mm on the surface, making the wood grain texture more refined and producing a distinct tactile feel. Clean the glass plate surface 3~5 times with 75% industrial alcohol, following the engraving direction, to remove stains. Apply air spray to the glass plate surface using a 0.8mm nozzle; the air pressure supplied to the spray gun is 0.5Mpa; the distance between the nozzle and the surface being sprayed is 25cm. Spray an adhesion promoter (8% organosilane, balance isopropanol), and let it stand for 15 minutes to prevent poor adhesion for subsequent coloring.

[0060] The scheme in Comparative Example 1, unlike the scheme in Example 4, did not undergo laser engraving but was directly UV 3D printed. A comparison of the glass plate obtained from Comparative Example 1 (left) and the glass plate obtained from Example 4 (right) is shown below. Figure 5 As shown, the simulated wood grain texture of the glass plate without laser engraving is not refined enough, lacks a 3D effect, and has no obvious tactile feel.

[0061] Comparative Example 2 Place the plastic board to be produced with simulated wood grain on a fixed hanger with the flat outer surface facing outwards and kept at the same level. Put the plastic board into an ultrasonic cleaning tank containing 15% ethylenediamine oleate, 12% C13 isopropanol amide, 2% emulsifier and the balance water. Ultrasonic cleaning is performed at 50℃ for 3 minutes. After ultrasonic cleaning, rinse with pure water 3 times.

[0062] Place the ceramic plate in the laser engraving machine's work area. The machine uses a 60W power setting and a 1000mm / s engraving speed to laser-engrave irregular wood grain texture lines with a depth of 0.01~1mm on the surface of the material, making the wood grain texture more refined and producing a distinct tactile feel. Clean the plastic plate surface 3~5 times with 75% industrial alcohol, following the engraving direction, to remove stains. Apply air spray to the plastic plate surface using a 0.8mm nozzle; the air pressure supplied to the spray gun is 0.5Mpa; the distance between the nozzle and the surface being sprayed is 25cm. Spray an adhesion promoter (5% organosilane, balance isopropanol), and let it stand for 15 minutes to prevent poor adhesion during subsequent coloring.

[0063] After applying the adhesion promoter, the plastic board is laid flat on the UV 3D printing machine platform and positioned. The 3D UV printing equipment is then started to print the 3D wood grain pattern and color, which has been processed by the image software, in layers. White ink is pre-printed to a height of 0.01~0.5mm to create a three-dimensional wood grain effect. Then, 1~7 layers of colored paint are printed on the pattern to form a three-dimensional and layered wood grain texture.

[0064] Compared to Example 3, Comparative Example 2 did not perform an air-spraying UV coating after forming the three-dimensional, layered wood grain; the simulated wood grain was completed after UV 3D printing. A comparison of the plastic sheet obtained by the preparation method of Comparative Example 2 (left) and the plastic sheet obtained by the preparation method of Example 3 (right) is shown in the figure. Figure 6 As shown, the surface of the material with simulated wood grain obtained without a UV coating is easily damaged and scratched.
