A pattern printed layer is formed between the base material 1 and the polyvinyl chloride resin layer 3, onto the polyvinyl chloride resin layer 3 and onto at least one surface of the surface of the film 4 and embossing is executed onto the surfaces as required.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a matte interior material used for the interior of buildings such as wallpaper and floor materials.

[0002]

2. Description of the Related Art Generally, an interior material is a base material such as paper,
In many cases, a layer of polyvinyl chloride, which is an inexpensive material that is easy to process, is provided, and appropriate printing or embossing is performed.

[0003] Consumers' demands for interior materials are becoming more and more advanced, and at present, it is preferred that the interior materials have a matte and fluffy atmosphere and a soft feel.

As an interior material satisfying such requirements, it has been attempted to provide a coating film containing a matting material known as so-called bead pigment on the surface of an interior material using a commonly used polyvinyl chloride. However, this interior material has a problem of poor durability. The reason is as follows.

That is, it is suitable to use an aromatic solvent such as xylene, which is excellent in the dispersibility of the bead pigment, as a diluent solvent for the paint to which the bead pigment is added, which is used in the production of the interior material. However, xylene has relatively low volatility in the solvent, and requires high temperature and long time for drying the coating film. When the coating film is dried at high temperature for a long time, the solvent in the coating film deteriorates the polyvinyl chloride of the base material,
At the same time, the plasticizer in the polyvinyl chloride exudes and deteriorates the coating film.

[0006]

SUMMARY OF THE INVENTION In consideration of the above problems, an object of the present invention is to provide a matte interior material which can realize a high degree of design, has a good feel, and is also excellent in durability. It is in.

[0007]

As shown in FIG. 1, the matte interior material of the present invention basically comprises a base material (1) and a synthetic resin layer (2) containing a bead pigment added thereto. It will be provided.

Since it is easy to manufacture and it is possible to concentrate the bead pigment on the surface at a high density, 2-methoxyethanol, 2-ethoxyethanol and 2-butoxyethanol are used as diluent solvents. A preferred embodiment is one in which a polyvinyl chloride sol using a solvent is coated with a coating material formed by adding a bead pigment, and the polyvinyl chloride resin layer (2) gelled by heating is provided.

Another embodiment of the matte interior material of the present invention uses a polyvinyl chloride resin layer (3) on a substrate (1) and the above-mentioned solvent as a diluting solvent, as shown in FIG. Applied a paint containing a bead pigment,
A coating film (4) heated and dried at a temperature of 20 ° C. is sequentially provided. Since the bead pigment is expensive and its presence is significant on the surface, the latter mode of concentrating the bead pigment only on the surface of the interior material is advantageous in terms of cost.

The base material is appropriately selected according to the use of the interior material. If the interior material is used as wallpaper, various kinds of paper such as backing paper for wallpaper and cloth such as woven or non-woven fabric such as glass wool and rock wool are suitable, and used as floor material. If you do, polyvinyl chloride or bitumen with calcium carbonate added,
The one to which glass fiber is further added is suitable.
In addition, wood board, gypsum board, ceramics board, metal board, plastic sheet, etc. can be used.

The coating of the polyvinyl chloride sol and its gelation by heating may be carried out according to a known technique using a comma coater, a knife coater or the like.

The resin layer may be formed by coating a polyvinyl chloride sol on a base material, or by separately laminating a bead pigment kneading sheet formed by a calendar method or a casting method. The resin layer may be transparent, opaque, colorless or colored.
The thickness of the resin layer is 50 to 20 depending on the use of the interior material.
0 μm is suitable.

When a paint is used, the thickness is 20-100 μm.
m is suitable. The application may be performed by a known means using a flow coater or the like.

As the synthetic resin constituting the resin layer, polyurethane, polyethylene, polypropylene, polystyrene, cellulosic resin, rubber or the like may be used in addition to polyvinyl chloride. Generally, a soft and flexible material is preferable from the viewpoint of improving the scratch resistance of the surface containing the bead pigment.

The bead pigments are Fe ₂ O ₃ , TiO ₂ and Ca.
Fine powder of commonly used pigments such as CO ₃ and quinacridone is used as an elastic resin such as polyurethane, acrylic resin, epoxy, polyester, nylon, fluororesin, vinyl chloride-vinyl acetate copolymer, or a plasticizer if necessary. , Stabilizers,
It is a granulated product that is dispersed in a product to which a surface-active agent is added. The color of the bead pigment may be selected as desired. For example, if a substantially colorless and transparent bead pigment is used, a deep matte coating film can be formed, and even if two or more bead pigments are combined, a matte surface with a wide variety can be created. The particle size of the bead pigment has a particle size distribution of 5 to 80.
It is desirable that the maximum of distribution in μm is in the range of 10 to 35 μm.

As shown in FIG. 1, any of the interior materials of the present invention has a pattern printing layer (5) between the base material and the resin layer, on the resin layer, and on at least one surface of the coating film. May be provided, or embossing may be provided on the surface.

As a convenient embodiment for construction, adhesive processing (adhesive and release paper is laminated) is performed on the back surface of the base material, and the release paper is peeled off at the time of construction and adhered to the wall surface, or the back surface of the base material is reused. An example is a mode in which a moistening agent is applied and then moistened at the time of construction.

[0018]

By using a solvent selected from 2-methoxyethanol, 2-ethoxyethanol and 2-butoxyethanol as a solvent for diluting a paint or sol containing a bead pigment, the dispersibility of the pigment is good and the pigment volatilizes. It is quick, can be dried in a short time, and can prevent deterioration of the coating film and the resin layer at the time of manufacturing the decorative material, so that a matte interior material having excellent durability can be obtained.
