Problems solved by technology

But this has the following disadvantages: (1) To produce the floor, it is necessary to order the PVC color film first, which will cause the production cycle to be too long; (2) To solve the problem of the long production cycle, it is usually through the standing stock. Solved, but the standing inventory caused a large amount of unused color films to be piled up in the warehouse; (3) when ordering PVC color films, there is a minimum order quantity constraint for a single PVC color film of a certain pattern; (4) it is impossible to customize The PVC color film with the desired pattern can only be selected from the limited number of PVC color films provided by upstream suppliers
However, the method itself is relatively cumbersome to operate. Not only does it need to paint the primer or topcoat over and over again, but the primer or topcoat cannot be finished at one station, which seriously affects the production efficiency.

Embodiment 1

[0044] An SPC-based 3D printing board, the board comprising a stone plastic (SPC) substrate layer, a color layer presented on the stone plastic (SPC) substrate layer by 3D printing, and UV covering the color layer Protective layer; the stone plastic (SPC) substrate layer includes a stone plastic (SPC) core layer and a background film layer compounded with the stone plastic (SPC) core layer; the material of the background film layer is PVC; the The background film is also embossed with wood grain texture. The color of the background film layer is white with covering properties.

[0045] Reference figure 1 with figure 2 , A preparation method of SPC-based 3D printing plate, including the following steps:

[0046] a. Add the raw materials and additives that constitute the core layer of stone plastic (SPC) into the main extruder, and the raw materials and additives that constitute the core layer are melted through the main extruder and extruded into the main runner 10 of the mold , ...

Embodiment 2

[0052] The difference from the first embodiment is: change step b to: change the PVC film that constitutes the background film layer, through unwinding and the core layer of SPC stone plastic material obtained in step a, through on-line rolling composite, to obtain the SPC substrate The precursor structure of the layer. In this embodiment, the PVC film is a preformed film; and in the first embodiment, the PVC film is co-extruded with a core layer formed of a stone plastic (SPC) material through an extruder.

Embodiment 3

[0054] The difference from the first embodiment is: change step b to: change the PVC film that constitutes the background film layer, through unwinding and the core layer of SPC stone plastic material obtained in step a, through on-line rolling composite, to obtain the SPC substrate Floor;

[0055] Change step c to: input the SPC substrate layer obtained in step b into the pattern printing area of ​​the 3D online printing device, and print a flat wood grain, pattern or pattern on the SPC substrate layer to obtain intermediate product one;

[0056] Change step d to: input the intermediate product 1 obtained in step c into the concave-convex effect molding area of ​​the 3D online printing device, and print the concave-convex effect layer to obtain intermediate product two;

[0057] Change step e to: coat the second intermediate product obtained in step d with a UV primer and a UV topcoat, and light-cure them separately to form a UV protective layer.

[0058] According to GB / T17657-2013 ...

Abstract

The invention relates to an SPC-based 3D printing plate, and belongs to the technical field of plate manufacturing. The board comprises an SPC base material layer, a 3D printing color layer and a UV protection layer. Wherein 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; wood grains, decorative patterns or pattern textures are also embossed on the background film layer; or the SPC base material layer comprises an SPC core layer and a background film layer which is compounded with the SPC core layer through online pressing, and the SPC base material layer further comprises a resin concave-convex effect layer which is arranged between the color layer and the UV protective layer. According to the invention, the background film layer which can be made of a PVC material is compounded on the SPC base material layer, so that (1) the PVC board base material is effectively replaced; the method comprises the following steps of (1) preparing a PVC board base material, (2) coating UV primer on the upper surface of the PVC board base material, (3) drying and curing the UV primer, (4) coating whiteUV finish paint, and (5) curing and drying UV white paint, so that the production process is simplified, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to a printing plate, in particular to an SPC-based 3D printing plate and a preparation method thereof. It belongs to the technical field of SPC-based indoor flooring. Background technique [0002] The process of producing SPC-based indoor flooring in the prior art is: the extruder first extrudes the SPC substrate containing PVC, and then separately heat the PVC base film, PVC color film, PVC wear-resistant layer and SPC substrate through a four-roll calender. Compressed and compounded. Synchronize the flowers during the pressing process to achieve the effect of imitating wood texture. But this has the following disadvantages: (1) To produce the floor, you need to order the PVC color film first, and the PVC color film is scheduled first, which causes the production cycle to be too long; (2) To solve the problem of the production cycle is too long, usually through standing inventory. To solve the problem, but the standing inventory ca...
