SPC-based 3D printing plate and preparation method thereof

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...

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.
