Technical Field

The invention relates to a plate seam imitating method based on an embossing technology and an seam imitating plate, and belongs to the field of building decoration materials.

Background

The edge joint is commonly used in tile pavement, and putty powder, filler or glue substances and the like are filled in the gap after the tile pavement, so that the edge joint, also called as a beautiful joint, is formed. The seam-beautifying floor is regular in splicing and attractive in appearance, and the visual effect of the ceramic tiles can be improved. With the development of the market, people adopt plastic floors and the like to replace part of tiles, but still hope that the plastic floors are provided with beautiful seams at the joint of units to achieve the effect of imitating the tiles. The traditional method for making the seam beautifying of the plastic floor is to cut the edge of a plate, so that the bottom color of the plate can be exposed, different colors need to be printed on the cut part, or a color film is pressed to cover the bottom color, and the effect of imitating the seam beautifying is achieved. However, this method has the following problems: firstly, one more seam beautifying process is adopted for the plates, so that time and labor are wasted, and the cost is increased; secondly, the pattern position is difficult to control in the printing or film pressing process, and the pattern position of the seam beautifying is not matched when the plate is paved, so that the seam beautifying effect is influenced.
