JPS599674B2 - Colored sheet for fiber walls - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a colored sheet for expressing a colored pattern on a fiber wall.

Conventionally, patterns on fiber walls have only been irregularly shaped by adding coloring additives to a fibrous top coating material, and there have been no patterns that have clearly defined shapes.

Therefore, the colored sheet of the present invention was developed.

In other words, by cutting this sheet into a desired shape and pasting it on a wall, and then applying a fibrous topcoat over it, the shape and color of the sheet will stand out on the surface, creating a clear shape. As shown in the figure, the colored sheet of the present invention is made by adhering a water-soluble colorant and fine solid matter 1 onto a sheet 2 with a water-soluble adhesive.

In the figure, 3 is a mixture of a water-soluble colorant and a water-soluble adhesive, 4 is a wall, 5 is an adhesive, and 6 is a fibrous top coat material. Because the colorant is fibrous, it dissolves when the coating material is applied.
Since it only needs to be colored, anything is acceptable as long as it is water-soluble. Dyes are usually used, and direct dyes are particularly preferred.
The purpose of the fine solids is to prevent the colorant from eluting too quickly, spreading the color and making the shape unclear, and also to make the sheet surface rough so that it is easier to work with when applying the core coating material. This is to do so.

Therefore, there are almost no restrictions on the materials and shapes, including rubber powder, wood flour, perlite grains, millet powder, metal powder, powder powder,
It may be granular material such as resin powder, fibers such as cotton, flakes such as cloth pieces, paper pieces, or a mixture thereof. When using powder or granules, there are no restrictions on the particle size, which is 16 to 3.
00 mesh can be used, preferably 16 to 90 mesh.
It is a mesh one, and one of about 20 mesh is optimal. When using fibers, the length of the fibers is preferably 157,727 or less. When flakes are used, their diameter is preferably 15 mm or less. The adhesive not only adheres the fine solid matter/colorant onto the sheet, but also controls the elution time of the colorant.

Adhesives include those that allow colorants to pass through;
That is, it is sufficient if it is water-soluble. Therefore, funori and starch glue can also be used, but CMC (carboxy methyl cellulose) is superior in terms of reliability and stability. Also, the sheet is made of paper, cloth, etc. This colored sheet is used as follows.

This colored sheet is cut into a desired shape and pasted on the wall with adhesive. A fibrous topcoat material is applied thereon by spraying or core coating in accordance with conventional methods. As the top coat dries, the colorant dissolves and the shape and color of the sheet stand out on the surface. Using this sheet, it is possible to draw a pattern with a clear shape on the fiber wall, which was previously impossible.

Next, in order to explain the present invention in more detail, manufacturing examples of colored sheets of the present invention will be shown. Production Example 20 Mesh rubber particles 15, O (weight ratio), 5
Dye, CMC, and water are kneaded in the proportions (weight ratio) shown in the table below.

Spray this onto the paper and let it dry.

If you use this colored sheet to apply the topcoat material with a trowel, it will be approximately 30%
The above color stands out in minutes.
