Description

DETAILED DESCRIPTION OF THE INVENTION As a conventional method for manufacturing decorative materials by applying different coats, a method has been proposed in which two types of paints that are more compatible 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. Another method is to apply organic solvent-based resin paints whose resin components are incompatible with each other one after another before the previously applied coating has substantially dried, and then dry to obtain a fine mosaic uneven pattern or a leather-like uneven pattern. There is. However, since both of these methods use organic solvents as solvents, even though the resin components are not compatible with each other, both solvents mix independently of the resin components, resulting in stability of the pattern. There was a drawback that it was difficult to obtain a pattern of a certain shape and size.

This invention eliminates the above-mentioned drawbacks,
In other words, two or more relatively incompatible paints, one of which has a solvent-free resin or an organic solvent-type resin as its main component, and the other paint with a water-soluble resin or an emulsion-type resin as its main component. After adding a coloring agent to at least one of them, a paint whose main component is a solvent-free resin or an organic solvent-type resin is applied to the surface of the base material, and a water-soluble resin or an emulsion-type resin is applied while the paint is not cured. This relates to a method for manufacturing a decorative material characterized by applying a paint as a main component, and the object is to provide a decorative material having a very natural net-like pattern at a low cost.

In this invention, both dyes and pigments can be used as the coloring material, 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, hardboard, steel plate, pulp cement board, calcium silicate board, etc., or those board materials that have been coated with a filler or undercoat, or those that have been previously painted. It refers to all kinds of things, such as paper, paper, synthetic resin film, cloth sheets, etc., or sheets with base coatings or decorative printing 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 a partially enlarged sectional view taken along line A-A in FIG. In the coating layer, a paint 3 whose main component is a solvent-free resin or an organic solvent-type resin with a colorant added is applied to the surface, and while it is not cured, a water-soluble resin or an emulsion-type resin is applied as the main component. After applying the paint 4 to the entire surface using an appropriate coating machine such as a roll coater, flow coater, or spray coating machine, and drying, the synthetic resin paint 4 applied later on the surface forms a net-like convex pattern. You will get plywood. I don't know the exact reason why this net-like convex pattern is formed, but I do not know the exact reason why this net-like convex pattern is formed. When used, the solvents do not mix with each other, or the resin content of solvent-free resins or organic solvent-type resins and the solvent of emulsion-type resins or water-soluble resins do not mix. During the final curing of the applied synthetic resin paint layer, when the next synthetic resin paint layer is formed on the surface, the difference in surface tension acts subtly and the paints repel each other on the contact surface, resulting in a uniform shape and size. This results in a stable net-like pattern.

With the above-described structure, the present invention makes it possible to produce an elegant decorative material that forms a very natural net-like pattern with a constant shape and size, without requiring any special means, by simply painting. , Moreover, first a paint mainly composed of a solvent-free resin or an organic solvent-type resin is applied or printed on the surface of the substrate, and then a paint mainly composed of a water-soluble resin or an emulsion-type resin that is difficult to dry is applied. Because of this, it dries easily and prevents the buildup that occurs when paints containing water-soluble resins or emulsion-type resins as their main components are applied before paints containing solvent-free resins or organic solvent-type resins as their main components. It has the advantage of being able to reliably dry and harden without the disadvantage that the surface is hardened but the inside is not.

Example 1 A thermosetting unsaturated polyester resin was colored with Pigment Yellow 5, and this was applied to the surface of a white base-coated steel plate using a 70 g/m ² flow coater, and a water-soluble epoxy resin clear was immediately applied.
After applying with 50g/ ^m2 flow coater, 30% at 80℃
The desired decorative material was obtained by oven drying for a minute.

Example 2 Clear lacquer was applied by spray at a rate of 30 g/m ² to the surface of an asbestos cement board coated with a red base coat, and immediately colored with Pigment Blue 15 and Butt Yellow 10 with a particle size of about 2 to 3 mm. An epoxy emulsion (viscosity: 50 CPS) was applied by spraying and dried at 50°C for 2 hours to obtain the desired decorative material.

Example 3 Heat-curable unsaturated polyester paint (viscosity
300CPS) was colored with Pigment Red 55 and applied discontinuously with a particle size of 2 to 3 mm by spray on the hardboard surface with a white base coat, and then immediately colored with Pigment Yellow 3, a water-soluble acrylic. Modified alkyd paint with curtain coater
A desired decorative material was obtained by applying 70 g/m ² and drying at 60° C. for 40 minutes.
