Description

DETAILED DESCRIPTION OF THE INVENTION As a conventional method for producing decorative materials by applying different coats, a method has been proposed in which two types of paints with good compatibility are used to form a flowing pattern. Furthermore, paints in which several types of colored particles are mixed are commercially available as multicolored paints, but all of these tend to have poor aesthetic appearance.

This invention eliminates the above-mentioned drawbacks,
That is, after adding a coloring agent to at least one of two relatively poorly compatible paints, one of the paints is applied or printed on the surface of the substrate, and while the paint is uncured, the other paint is mixed with the other paint. When forming a network pattern on the surface by applying or printing another paint with relatively poor compatibility, an appropriate pattern is applied to the surface while the paint forming the network pattern is not cured. This relates to a method for manufacturing a decorative material characterized by inhibiting the formation of a mesh pattern by printing, and the object is to provide at a low cost a decorative material having a very natural mesh pattern.

In the present invention, relatively incompatible paints include, for example, the following combinations of paints containing resin as a main component.

Solvent-free resin - water-soluble resin Solvent-free resin - organic solvent-type resin Solvent-free resin - emulsion-type resin Organic solvent-type resin - emulsion-type resin Organic solvent-type resin - water-soluble resin Water-soluble resin - emulsion-type resin In addition, even in combinations of water-soluble resins,
It is sufficient that one is a cationic modified water-soluble resin and the other is an anionic water-soluble resin.Also, even in the case of a combination of emulsion-type resins, one is an emulsion stable in methanol and the other is gelled in methanol. With such an emulsion, a mesh pattern can be formed.

In addition, as a method of printing a pattern to prevent a mesh pattern from forming in that area, one method is to print the mesh pattern by flexographic printing or textile printing before the mesh pattern area is completely cured. Methods that break the mesh pattern, or substances that inhibit the formation of the network pattern before it is formed, such as silicone resin, mineral oil, and solvents with relatively low surface tension (toluene, butanol, isopropyl alcohol, ethyl acetate, etc.) An example of this is a method of printing using a paint containing a liquid-producing agent such as methyl ethyl Kent, etc.).

In this invention, either a dye or a pigment can be used as a coloring agent, but for example, a dye that does not dissolve in the synthetic resin paint is added to the synthetic resin paint that is first applied, and this dye is applied later. If the dye has the property of being soluble in the synthetic resin paint that is applied, the dye will diffuse into the synthetic resin paint that is applied later, making it possible to obtain an extremely beautiful decorative material.

Conversely, if a dye added to a synthetic resin paint that is applied later does not dissolve in this synthetic resin paint, but has the property of dissolving in the synthetic resin paint that is applied first, the dye may A beautiful decorative material can be obtained by diffusing into the synthetic resin paint applied to the surface.

The relationship between the above dye and synthetic resin paint is as follows:
It is as follows.

There are two types of dyes: oil-soluble dyes and water-based dyes. Oil-soluble dyes dissolve in organic solvent-type synthetic resin paints, while water-based dyes dissolve in water-soluble synthetic resin paints, emulsion-type resin paints, or water-based dyes. -Dissolves in alcohol-based synthetic resin paints.

Examples of oil-soluble dyes include solvent yellow, solvent red, and solvent blue. Examples of water-based dyes include direct dyes such as direct yellow, direct red, and direct blue; acid dyes such as acid yellow, acid red, and acid blue; Reactive dyes such as active red and reactive blue, basic yellow,
Examples include basic dyes such as Basic Cret and Basic Blue. In addition, organic solvent-based synthetic resin paints used in combination with these dyes include polyester resins, amino resins, urethane resins, acrylic resins, etc. Water-soluble synthetic resin paints can be diluted with water. Examples include amino resins, acrylic resins, urethane resins, and the like.

In addition, in this invention, the base material refers to board materials such as plywood, particle board, steel plate, pulp cement board, calcium silicate board, etc., or these board materials coated with filler coating, base coating, or pasted with a resin sheet. Those that have been coated with a base coat, those that have been painted in advance or have a colored sheet attached during paper making,
It also refers to anything such as sheets of paper, synthetic resin film, cloth, etc., or those with base coatings or decorative prints on these sheets.

Further, in this invention, the paint includes ink.

This invention will be explained in detail below with reference to the drawings.

FIG. 1 is a plan view of a decorative material manufactured according to the present invention, and FIG. 2 is an enlarged sectional view taken along line A-A' in FIG. The transparent synthetic resin paint 3, which has relatively poor compatibility with the synthetic resin paint 2, is coated on the entire surface with a roll coater while it is still uncured.
When it is applied using a suitable coating machine such as a flow coater or a spray coating machine and then dried, a decorative material with a mesh pattern formed on the surface is obtained. Although we do not know the exact reason why this mesh-like pattern is formed, it is thought that because the two synthetic resin paints are relatively incompatible, the difference in surface tension may be at work. While the paint forming this network pattern is not cured, another synthetic resin paint 4 is applied to its surface.
After that, the top coat 5 is applied to the surface.
Paint. An anti-friction agent such as silica powder or alumina powder may be added to this top coat 5 to improve the abrasion resistance of the surface.

With the above structure, a natural mesh pattern is formed on the surface of the base material, and a slightly raised pattern with no mesh is formed on top of this mesh pattern, giving it a very elegant appearance. There is an effect that certain decorative materials can be manufactured by simply painting or printing without requiring any special means.

FIG. 3 is an enlarged sectional view taken along the line A-A' in FIG. 1 manufactured by another manufacturing method, and shows a synthetic resin paint 2,
A transparent synthetic resin paint 3, which has relatively poor compatibility with the synthetic resin paint 2, was applied in the same manner as in the embodiment shown in FIG.
During the formation, flexographic printing is performed in a pattern with another synthetic resin paint 4, water, or paint containing a liquid developer to prevent the formation of a mesh pattern in that part. When the paint contains a coloring agent, a colored concave pattern is formed as shown in the drawing. Further, if the paint is colorless and transparent, a simple concave pattern without a mesh pattern is formed.

When constructed as described above, a natural mesh pattern is formed on the surface of the base material, and within this mesh pattern, a concave pattern with no mesh is formed, creating a very elegant decorative material. It has the advantage that it can be manufactured by simple painting or printing without requiring any special means.
