Description
Technical Field
The invention relates to the technical field of floors, in particular to a processing method of a simulation seam beautifying, a simulation plate and a simulation plate group.
Background
Artificial boards are used in more and more applications in the field of decoration, such as floors and walls. The PVC board has the advantages of light weight, simple and convenient installation, water resistance, moisture resistance, moth resistance, various patterns on the surface, good performances of pollution resistance, flame retardance, sound insulation, heat insulation and the like, and the SPC (soft composite board) board is a short form of a hard multilayer composite PVC board and is a product formed by laminating and compounding a PVC color film, a PVC wear-resistant layer and a PVC bottom film at one time, the process is simple, the lamination is completed by heat, and no glue is contained.
However, when the existing PVC plate is installed, no gap or a small gap is left between the connected plates, and for the convenience of welding, the gaps of the existing plates are all in the shape of V-shaped grooves, so that the visual effect of seam beautifying does not exist between the plates, and in actual life, if the welding seams are not performed, the left small gaps bring great inconvenience to cleaning, and liquid easily seeps from the gaps, so that the service life of the PVC plate is influenced.
Moreover, a series of operations such as paying-off, paving and welding are needed during construction of the simple PVC plate, and construction is time-consuming. But the lock catch type PVC plate can directly lock the plates together, and the construction is very convenient. However, the seam beautifying visual effect of the existing lock catch type PVC plate is not ideal, and especially when the SPC plate for preventing the ceramic tiles such as marble is installed, if the seam beautifying visual effect of the ceramic tiles is not adhered, the SPC plate cannot be consistent with the ceramic tiles in visual perception.
Disclosure of Invention

Moreover, when the wood board is used, barbs are easy to be formed on the chamfer, so that the appearance is influenced and the adhesive force of the coloring layer is influenced.
The colors colored in the coloring step in the present invention include, but are not limited to, gray, black, white, and light gray, and the colors of the coloring are selected according to actual needs, wherein the gray is close to the color of the cement material.

The measurement methods of the simulated beautiful seams prepared in the embodiments and the comparative embodiments are classified into visual observation of color overflow condition, visual observation of glossiness, visual observation of wrinkle condition and adhesion evaluation.
The adhesion evaluation test can be roughly classified into the following three grades:
the method has the advantages that: the adhesive tape is stuck on the simulated beautiful seam, and is pressed and drawn once by fingers, after the adhesive tape is quickly torn off, the coloring layer does not obviously drop (the dropping area accounts for less than 1 percent of the total sticking area, namely the coloring layer does not drop basically).
Good: the adhesive tape is stuck on the simulated beautiful seam, and is pressed and drawn once by fingers, after the adhesive tape is slowly torn off, the coloring layer does not obviously drop (the dropping area accounts for less than 30 percent of the total sticking area).
Poor: the surface of the simulated beautiful seam is scratched by fingers, the coating obviously drops or the adhesive tape is stuck on the simulated beautiful seam, and the coloring layer obviously drops (the dropping area is more than 30 percent of the total sticking area) after the adhesive tape is slowly torn off after the coating is scratched once by fingers.
The simulated beauty seams obtained in all the embodiments have luster, and the transferred coloring layer has no obvious wrinkles and no obvious color overflow phenomenon.
