Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a decorative material having a penetrating pattern made of colored granules, and a method for producing the same.

Flooring materials with a penetrating pattern (so-called inlaid flooring materials) are conventionally known as shown in Japanese Patent Publication No. 58-111569. However, conventional inlaid flooring has patterns that are too bright, unnatural and deep, making the design unsatisfactory for consumers, and often resulting in patterns with a natural image similar to gradation patterns. .

Several proposals have been made to obtain inlaid seams with gradation patterns, but these include a method in which the pattern is formed using multiple plates while gradually changing the shape of the stencil opening, and a method in which the color of the underlying colored layer is hidden. There is a method in which colored granules are stacked in a pattern so thinly as to be less than t+.

The former method is not preferable because there are so many plates that the equipment becomes expensive and still occupies a large space.

However, in the latter case, the gradation pattern is limited to only a very thin part of the surface, and is not good over the entire thickness, and the durability of the gradation pattern part is weak.

The first object of the present invention is to provide a decorative mold that can impart a suitable blurred pattern to an inlaid pattern over the entire thickness and has a harmonious and improved design, and a method for manufacturing the same. A second object of the present invention is to provide a decorative material in which a pattern is formed over the entire thickness within a small unit pattern surrounded by a ground portion, and a method for manufacturing the same.

The first invention of the present application has a plurality of printed pattern areas made of colored granules formed continuously, and the colored granules at the boundaries of the printed pattern areas are mixed with different colored granules in the adjacent printed pattern areas. The gist of this is a decorative pattern with a blurred pattern.

This will be explained below based on the drawings.

The printed pattern area of the obtained colored granules is continuously formed except for the joint areas. This sheet is then covered with a shielding material 23 at the edge of the wire mesh cylinder 24 and guide roll 26, and the shielding side 28 is masked to prevent colored particles from entering the joints, causing the pattern at the joints to be distorted. prevent. A brush 25 is provided in the shielding area of the wire mesh cylinder 24, and the brush is exposed from the shielding area, and by rotating the brush, the printed pattern area is brushed and colored granules are produced! 7. The colored granules of a different color in the adjacent printed pattern area are mixed with the colored particles.

A brush device 25 is used to brush the boundary portions of the pattern areas to mix colored particles of different colors in the mutually adjacent printed pattern areas 14, 15, 15, 16, 16, and 17. A rotating brush may be used.

After the shielding material is removed, a joint portion 22 is formed by a printing device J that is synchronized with the joint pattern. Note that in the present invention, the shielding side and the brush may be provided on a flat plate stencil.

Preferably, the brush contacts the entire thickness of the granulate.

Subsequently, heating and pressure molding is performed using a heater 27 and a press device 28°28'. When applying pressure, it is desirable to use an embossing roll that is aligned with the joint area.
