The mosaic three-dimensional PVC flooring of the present invention is produced by a process similar to that of a conventional flooring, but unlike the conventional PVC mosaic flooring, the flooring has the same effect as the three-dimensional pattern of the mosaic without using mosaic pieces. The layer structure constituting the flooring material is formed from the top in the order of a UV coating layer, a transparent upper layer, a base layer having a three-layer structure consisting of a center layer, a base layer, and a balance layer. The transparent upper layer may be a single layer structure, a two-layer structure, or a three layer structure by adjusting the number of layers of the upper layer as necessary, and the material of the transparent upper layer and the underlying layer is PVC, and in the case of the underlying layer, Mainly use recycled PVC. In addition, the underlying layer may be a two-layer structure consisting of a single layer and a balance layer, in which a center layer and a base layer are formed in one unitary structure as needed.

Among the manufacturing methods of the mosaic three-dimensional pattern PVC flooring of the present invention, the manufacturing process of the mosaic pattern is as follows.

First, when the mosaic pattern and the shape of the design are determined, the size (dimension) and the color of the mosaic shape are selected, and the mosaic shape design is divided into the mosaic protrusion pattern and the background background pattern, and the bottom surface of the transparent upper layer layer ( The back side) is a mosaic projecting pattern that can emphasize the mosaic three-dimensional pattern, the upper surface (surface) of the underlying layer is transferred by the background background pattern, respectively, and then bonded to each other is produced by a conventional flooring manufacturing process. At this time, the printing paper used is a thermal transfer paper, and the method of transferring the pattern is transferred using a flat plate heat press in the case of producing a small amount of small articles, and using a roll type heat press in the case of mass production of small species.

The main purpose of the mosaic three-dimensional pattern PVC flooring of the present invention is used as an interior decoration for the interior of the elevator, interior floor decoration for the building or interior decoration.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
