Description

DETAILED DESCRIPTION OF THE INVENTION This invention 1d provides a first synthetic resin coating using a synthetic resin coating in which 40 to 300 parts by weight of a filler is added to 100 parts by weight of the resin content of the synthetic resin on the surface of a base material. After forming the layer, and while it is still uncured, a second synthetic resin paint layer is applied onto the first synthetic resin paint layer using a synthetic resin paint that is relatively incompatible with the synthetic resin paint used when first applied or printed. A decorative material characterized in that a synthetic resin paint layer is formed, dried and cured, and a mottled convex pattern is formed on the surface of the first synthetic resin paint layer by the synthetic resin paint containing a filler. The purpose is to provide a decorative material having a very natural mottled convex pattern using a simple manufacturing method.

One important aspect of this invention is that the two types of paints are relatively incompatible with each other.

This relatively incompatible paint may be, for example, the following combination of paints containing resin as a main component.

■ Organic solvent type resin - emulsion type resin ■ Organic solvent type resin - water soluble resin ■ Water soluble resin - emulsion type resin In addition to the above, even in combinations of water soluble resins, one is a cationically modified water soluble resin and the other is a cationically modified water soluble resin. Any anionic water-soluble resin may be sufficient, and even in the case of a combination of emulsion-type resins, it is sufficient to achieve the object of the present invention if one is an emulsion stable in methanol and the other is an emulsion that gels in methanol. I can do it.

Another important point in this invention is to add a filler to the synthetic resin paint used during initial coating or printing.

As the filler, quartz powder, α-alumina, talc powder, magnesium carbonate powder, glass peas, kaolin, calcium carbonate powder, talc, zinc white, etc. can be used.

The size of this filler is preferably about 5 to 200μ,
It is not limited to this.

Further, the amount of filler added is required to be 40 to 300 parts by weight per 100 parts by weight of the resin content of the synthetic resin coating.

If the amount of filler added is less than 40 parts by weight, no mottled convex pattern will be produced, and if it exceeds 300 parts by weight, not only will it be difficult to form a mottled convex pattern, but the workability will be poor.

In addition, in this invention, the base material refers to board materials such as plywood, particle board, bird board, steel plate, pipe cement board, calcium silicate board, etc., or these board materials are coated with filler,
Items with a base coating, items with a base coat attached by pasting thin paper or resin sheets, items with a colored sheet pasted that has been painted in advance or colored during papermaking, or sheets of paper, synthetic resin film, cloth, etc. This refers to all types of sheets with base coating and decorative printing.

In addition, in this invention, paint includes printing ink,
The synthetic resin paint layer is formed by painting or printing.

In this invention, a coloring agent such as a pigment or dye may be added to the synthetic resin paint.

Furthermore, if a dye is used as a coloring agent, and the dye has a property that it does not dissolve or is difficult to dissolve in the synthetic resin to which it is added, but it dissolves easily in the other synthetic resin paint, the dye can be used as a coloring agent. An extremely beautiful decorative material can be obtained by diffusing from one synthetic resin paint to another synthetic resin paint.

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

There are two types of dyes: oil-soluble dyes and water-based dyes.In the case of oil-soluble dyes, they are dissolved in organic solvent-type synthetic resin paints.In the case of water-soluble dyes, they are dissolved in water-soluble synthetic resin paints and water-alcohol type synthetic resin paints. , dissolves in emulsion-type resin paints, etc.

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; Examples include reactive dyes such as Active Red and Reactive Blue, and basic dyes such as Paysic Yellow, Paysic Red and Paysic Blue.

In addition, organic solvent type synthetic resin paints used in combination with these dyes include polyester resins, amino resins, urethane resins, acrylic resins, etc.
Examples of water-based synthetic resin paints include amino resins, acrylic resins, and urethane resins that can be diluted with water.

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 cross-sectional view taken along line A-A' in FIG. A synthetic resin paint 3 in which 40 to 300 parts by weight of filler 4 is added to 100 parts by weight of the resin content of the synthetic resin is applied to the surface of the film layer in a pattern.

While this synthetic resin paint 4 is not cured, the synthetic resin paint 3
When the synthetic resin paint 5, which has relatively poor compatibility with the first synthetic resin paint layer, is applied to the entire surface using an appropriate coating machine such as a roll coater, curtain coater, or spray paint machine, and then dried, the surface of the first synthetic resin paint layer is coated. A decorative plywood is obtained in which a mottled convex pattern is formed using a synthetic resin paint containing a filler.

The exact reason why this mottled convex pattern is formed is not known, but the two plywood resin paints are relatively incompatible, and the synthetic resin paint that is first applied or printed contains a certain percentage of filler. The addition of , and the difference in surface tension between synthetic resin paints work subtly, and when the synthetic resin paint that is later applied or printed displaces some of the synthetic resin paint underneath and dries and hardens, its volume shrinks. It seems possible.

Since the present invention is constructed as described above, it has the advantage that an elegant decorative material having a very natural mottled convex pattern can be manufactured by simply painting or printing.
