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

Abstract

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.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to a process of making decorative flooring materials and a decorative flooring material made by the process. [0002]FIG. 7 is an illustration of a decorative flooring material 110 currently in used. The reference numeral 1 is a base material of plywood, MDF, or the like. A decorative sheet 2 is pasted on the base material 1 with an adhesive. V-shaped grooves 113 are made in the decorative sheet 2 and base material 1 to (i) make the joints between decorative flooring materials 110 inconspicuous, (ii) absorb the variation of dimensional accuracy of decorative flooring materials 110 and make the alignment of decorative flooring materials 110 easy, and (iii) give the decorative flooring material 110 a good appearance. If decorative flooring materials 110 are given V-shaped grooves 113 as narrow as 1 mm, the floor looks trim. If decorative flooring materials 110 are given V-shaped grooves 113 as wide as 3 or 4 mm, the floor looks s...

AI Technical Summary

Benefits of technology

[0013] (1) Because the pressing protrusions of the pressing die are wider than the temporary V-shaped grooves, strong pressure is applied to the grooves; accordingly, the close adhesion of the decorative sheet to the base material is accomplished. The decorative sheet does not easily peel off the base material. The good appearance of the decorative flooring material is kept long and the life of the decorative flooring material is long.

[0016] According to the second invention, the V-shaped grooves with curved slopes are finished by the V-shaped pressing protrusions of the pressing die and the slopes of each V-shaped pressing protrusion are paraboloidal; therefore, the slopes of the V-shaped grooves with curved slopes are paraboloidal, the grooves assuming a soft appearance. The edges of the decorative sheet do not peel easily. The good appearance of the decorative flooring material is kept long and the life of the decorative flooring material is long.

Problems solved by technology

The decorative sheet does not easily peel off the base material.
