Process of making decorative flooring materials and decorative flooring material made by the process

摘要

The present invention provides (i) a process of making decorative flooring materials, which have elegantly designed V-shaped grooves with curved slopes and of which the decorative sheets hardly peel off the base materials, and (ii) a decorative flooring material made by the process, which has elegantly designed V-shaped grooves with curved slopes and of which the decorative sheet hardly peels off the base material. The process of making decorative flooring materials comprises the steps of (i) pasting a decorative sheet 2 on a base material 1 to make a decorative flooring material 10, (ii) cutting temporary V-shaped grooves in the surface of the decorative flooring material 10 which are narrower than finished V-shaped grooves with curved slopes, (iii) positioning V-shaped pressing protrusions of a pressing die 6 above the temporary V-shaped grooves, the slopes of each V-shaped pressing protrusion being paraboloidal and symmetrical, (iv) pressing the V-shaped pressing protrusions into the temporary V-shaped grooves to form the V-shaped grooves with curved slopes 3, the edges of the decorative sheet along the temporary V-shaped grooves covering the curved slopes partially, (v) painting the curved slopes in the same color as the decorative sheet 2, and (vi) painting the entire surface of the decorative flooring material 10.
