All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.
The invention relates to a method for manufacturing a 3D steel plate panel, which comprises the following steps:
the method comprises the following steps: preparing a silica gel mold; and engraving pattern textures on the surface of the silica gel sheet with the thickness of 20mm by using a photoetching machine to form the silica gel mold 2.
As shown in fig. 2, the pattern is composed of blind holes 3 of different sizes. The blind hole 3 can be a circular hole, or a hole with other shapes, such as a cross section with a triangular, rectangular or polygonal shape. The depth and the diameter of the blind holes 3 forming the pattern texture and the included angle between the inner bottom surface and the surface of the silica gel sheet are different, the integral depth range is 5-12 mu m, the diameter distribution range is 15-60 mm, and the included angle distribution range between the inner bottom surface of the blind holes 3 and the surface of the silica gel sheet is more than or equal to 0 degrees and less than 90 degrees. The surface of the silica gel sheet can be provided with textures in partial areas, and the partial areas are not provided with the textures; the engraving of the texture can also be carried out entirely.
Step two: pretreating a steel plate; the thickness of the steel plate is 0.45mm, and the steel plate is sequentially subjected to degreasing passivation, washing, primary coating and intermediate coating.
Step three: transferring textures; dipping the silica gel mold 2 with UV glue, filling UV glue into the blind holes 3 forming the pattern texture in an arranging mode, scraping redundant UV glue on the surface of the silica gel mold 2, impressing one side of the engraved pattern texture of the silica gel mold 2 on the surface of the steel plate 1 pretreated in the step two, moving out the silica gel mold 2, transferring the UV glue filled in the blind holes 3 on the surface of the steel plate 1 in a shape of a columnar structure, and forming the texture of the pattern through the columnar structure in an arranging mode.
As shown in fig. 1, the shape and size of the columnar structures constituting the texture are determined by the blind holes 3, and thus, the diameter and height of the columnar structures are different, for example, the diameter distribution range of the columnar structures is 15mm to 60mm, and the height distribution range of the columnar structures is 5 μm to 12 μm.
The included angle between the upper end surface of the columnar structure on the surface of the steel plate 1 and the surface of the steel plate 1 is different in size. Specifically, the distribution range of the included angle α between the upper end surface of the columnar structure and the surface of the steel plate 1 is greater than or equal to 0 ° and less than 90 °. If the upper end surface of the part of the columnar structure forming the texture is parallel to the surface of the steel plate 1, namely the included angle alpha is equal to 0 degree, and the upper end surface of the part of the columnar structure forming the texture and the surface of the steel plate 1 form an included angle alpha of 75 degrees.
Step four: preparing a texture layer; and conveying the steel plate 1 subjected to transfer printing with the UV glue to an ultraviolet curing chamber, and irradiating for 10-30 s by using an ultraviolet lamp at room temperature to cure the UV glue to form a pattern texture layer.
The shape and size of the columnar structure can be adjusted by adjusting the diameter, depth and angle of the blind holes, so that the pattern texture layer is adjusted, the texture has a 3D stereoscopic visual effect, and different visual experiences can be combined. Even under the premise that the size, the depth and the angle of the columnar structure are fixed, visual observers can still see different visual effects at different observation positions.
Step five: and coating transparent finish on the surface of the pattern texture layer in a roller coating mode, and curing the finish through a hot baking channel at 180 ℃ to form a transparent finish layer. The transparent topcoat layer protects the pattern texture layer from external impact and improves the weatherability of the coating.
Through fine texture design, the diameter, depth and angle of blind holes of the texture are controlled, UV glue is transferred to the surface of the steel plate 1 and is in a columnar structure, the texture of patterns is combined and arranged through the columnar structure, and therefore the 3D visual effect is achieved on a common steel plate. Thoroughly subvert the outward appearance of traditional steel sheet, promoted steel sheet grade by a wide margin. Meanwhile, the process flow is simple, efficient and stable in quality.
