Description

SPC-based 3D printing plate and preparation method thereof
Technical Field
The invention relates to a printing plate, in particular to an SPC-based 3D printing plate and a preparation method thereof. Belongs to the technical field of SPC-based indoor floors.
Background
The process for producing SPC-based indoor floors in the prior art comprises the following steps: the extruder firstly extrudes the PVC-containing SPC base material, and then the PVC base film, the PVC color film, the PVC wear-resistant layer and the SPC base material are compounded through hot pressing by a four-roll calender. And the patterns are synchronously aligned in the pressing and pasting process, so that the effect of imitating wood textures is realized. However, this has the following disadvantages: (1) the production of the floor needs to reserve a PVC color film firstly, and the production period is too long due to the reservation of the PVC color film firstly; (2) the problem of overlong production cycle is solved by stock preparation usually, but the stock preparation leads to a large amount of color films which are not used up being accumulated in a warehouse; (3) when a PVC color film is preset, the PVC color film with a single certain pattern is restrained by the minimum amount of orders; (4) PVC color films having the customer's actual desired pattern cannot be customized and can only be selected from a limited number of PVC color films provided by upstream vendors.
The Chinese patent application with the application number of 201811628557.4 discloses a 3D effect PVC decorative plate and a 3D printing production method thereof. The manufacturing process of the plate is as follows: 1) cleaning a PVC board base material; 2) coating UV (ultraviolet) primer on the upper surface of the PVC board substrate; 3) drying and curing the UV primer; 4) coating white UV finish paint; 5) curing and drying the UV white paint; 6) printing patterns by a flat plate ink-jet printer; 7) coating UV wear-resistant paint; 8) curing and drying the UV wear-resistant paint; 9) printing a concave-convex effect layer by a flat ink-jet printer; then UV lamp irradiation curing; 10) coating UV finish paint; 11) and (5) curing and drying. The scheme subverts the traditional production mode that the color film needs to be ordered first, solves the problems of inventory, long production period, least order limitation and individual requirement at a stroke, and has remarkable effect on the production and management of SPC indoor floor production enterprises. However, the method is complicated in operation, not only the primer or the finish paint needs to be coated one time and another time, but also the coated primer or finish paint cannot be finished on one station, and the production efficiency is seriously influenced.
Disclosure of Invention
The invention aims to solve the technical problems and provides an SPC-based 3D printing plate. The plate has a hierarchical structure different from any plate in the prior art, and the specific hierarchical structure ensures that the plate of the invention has the characteristic of high production efficiency on the basis of keeping the performance characteristics of the original plate.
The technical scheme for solving the problems is as follows:
an SPC based 3D printed panel, the panel comprising an SPC substrate layer, a colour layer presented on the SPC substrate layer by 3D printing and a UV protective layer overlying the colour layer; the base material layer comprises an SPC core layer and a background film layer which is compounded with the SPC core layer through co-extrusion; the background film layer is also imprinted with textures in the form of wood grains, patterns or patterns;
or the SPC base material layer comprises an SPC core layer and a background film layer which is compounded with the SPC core layer together through online laminating, and further comprises a resin concave-convex effect layer, wherein the resin concave-convex effect layer is arranged between the color layer and the UV protective layer.
In the technical scheme of the invention, the background film layer which can be made of PVC is compounded on the SPC substrate layer, so that the prior art that 1) the PVC board substrate is cleaned is effectively replaced; 2) coating UV (ultraviolet) primer on the upper surface of the PVC board substrate; 3) drying and curing the UV primer; 4) coating white UV finish paint; 5) curing and drying the UV white paint; ' A series of operations simplifies the production process, thereby improving the production efficiency.
In the technical scheme of the invention, the operation of firstly engraving and then printing the concave-convex effect layer is also subversively provided; based on the idea, a background film layer can be attached to the core layer, which is equivalent to the integration effect of steps 2) to 5) in 201811628557.4 Chinese invention patent, and the background film can be directly engraved through a printing roller, which is equivalent to the completion of steps 7) to 9), and then the concave-convex effect layer is printed through a flat ink-jet printer, which is equivalent to the completion of step 6); and finally, a UV protective layer is coated to effectively protect the printed concave-convex effect layer.
In the technical scheme of the invention, as the order of engraving and printing is inverted compared with the prior art, the UV protective layer is equivalent to simultaneously completing the steps 7) -8) and the steps 10) -11). Thus, the invention greatly shortens the process and greatly improves the operability of the process. In the prior art, since the pattern is printed firstly and then the pattern is patterned (the flat ink-jet printer prints the concave-convex effect layer), the pattern needs to be provided with a carrier, and the carrier can be a PVC white film or a paint layer, such as the integrated effect of step 2) to step 5) in the Chinese invention patent of 201811628557.4; however, in the present invention, the background film layer corresponds to the above-mentioned carrier, and in order to improve the production efficiency, the carrier is not attached by gluing or painted by painting; the PVC material is extruded on the surface of the SPC core layer through a co-extrusion technology, so that the controllability is good, the production efficiency is high, and the defects that the surface of a background film layer made of the PVC material extruded through co-extrusion is very smooth, the effect of directly printing patterns is not good, and even double images and other problems can occur; in the prior art, when the problem of poor effect of printing patterns (in the form of wood grains, patterns or textures of patterns) is solved, a layer of compatilizer is usually coated on the surface of a carrier in a rolling way, so that the problem can be relieved to a certain extent, but the problem cannot be solved effectively.
When the problems are solved, the method of exchanging the sequence of the printing pattern layer and the printing concave-convex effect layer is adopted, and the printing concave-convex effect layer is replaced by the rolling concave-convex effect layer on the background film layer made of PVC material; by doing so, on one hand, the problem of poor effect of directly printing the patterns is solved, because the roller engraving of the concave-convex effect layer (displaying the wood grains or the textures of patterns or other patterns) is firstly carried out, so that the surface of the background film layer made of the PVC material is not smooth any more; on the other hand, the method effectively shortens the working procedure, directly converts the operation required to be carried out on the flat ink-jet printer into the operation of carrying out on-line roll engraving after being extruded from the extruder, so that the process becomes simple and the controllability is improved; moreover, the 'inversion' mode also has obvious influence on the subsequent process steps, so that the process is further simplified, as disclosed in the Chinese invention patent of the prior art 201811628557.4, steps 2-5 and steps 10-11 are both coated with UV paint and then cured, namely, the prior art needs to process on two stations, and the 'inversion' mode of the invention omits the operation equivalent to steps 2-5 because the concave-convex effect layer is directly engraved on the background film layer, so that the painting and curing process only needs to be carried out on one station, which is equivalent to combining the original steps 7) -8) and steps 10) -11) into a whole, thereby forming the wear-resistant layer, namely the UV protective layer, of the invention together; also, with the method of the present invention, a simple roll-engraving machine can be used to replace expensive high-precision flat ink-jet printers for "printing a relief effect layer", significantly reducing production costs.
In order to achieve better wear-resisting and protecting effects, the wear-resisting layer is upgraded on the basis of one surface of one bottom in the prior art, for example, two surfaces of five bottoms, so that a remarkable protecting effect is achieved.
However, the 3D visual effect of the invention is slightly different from the prior art, the principle of the 3D visual effect of the invention is as same as that of watching small insects in amber, the surface of the product is flat and smooth, but the stereoscopic visual effect of the product can be intuitively felt; however, in the product produced by the prior art through a complex process, the surface of the product is concave-convex because the process of printing the concave-convex effect layer is carried out later, and the 3D stereoscopic effect is more direct, but the overall 3D visual effect is slightly uncoordinated because the pattern layer in the product is planar.
More importantly, in order to achieve the effect of synchronous registration, the requirement for printing a concave-convex effect layer by a flat ink-jet printer in the prior art is very strict, when the concave-convex effect is generated by impact, the original pattern needs to be strictly contrasted, the left-right deviation and/or the front-back deviation which are 1mm or smaller cannot be generated, and once the concave-convex effect and the pattern are not matched, the 3D visual effect is seriously responded; therefore, special equipment is needed, and tens of millions of investment is needed. In the invention, because the carving is carried out firstly and then the color deposition (printing) is carried out, at the moment, because the carving is carried out firstly, the effects of depth, brightness and the like are firstly generated, and the stereoscopic vision effect can be shown even if the same color is adopted; the principle of the snow is that generally, different places in the same area have different ground surfaces, after the snow falls indifferently, due to the reasons of angle light and the like, the snow in some places looks bright, and the snow in some places looks dark, and even gray. Similarly, when the invention performs the printing based on this principle after the engraving, it is not necessary to perform the high-precision registration of the flower (different colors are printed on different portions), and the 3D visual effect unique to the invention can be realized only by performing the printing without distinction. Of course, different colors are printed on different parts accurately by adopting a plurality of colors, so that a better 3D visual effect of the invention can be embodied.
Preferably, the color of the background film layer is white or light color with covering property.
Preferably, the material of the background film layer is PVC.
Another object of the present invention is to provide a method for preparing an SPC-based 3D printing plate as described above.
