2. Description of the Related Art Conventionally, as a sheet-like covering material, there is a wallpaper for interior of a building, but this does not take into account the durability when used outdoors. Japanese Patent Application Laid-Open No. Sho 59-1066 discloses a sheet-like surface covering material intended for application to an external surface.
No. 60 and JP-A-63-125332. The invention described in JP-A-63-125332 is simply a combination of a waterproof layer using a water-based elastic paint and a decorative layer using a cosmetic paint on a fibrous sheet (flame-resistant member). Further, the invention described in Japanese Patent Application Laid-Open No. 59-106660 discloses a method of embedding a mesh base material in a base plate so that the base plate and the imitated tile surface are coated with different types or different colors of coating material in order to form a dummy tile shape. Formed.

Prior to this application, the present applicant proposed a surface covering material applicable to the outer wall surface of a building in Japanese Patent Application No. 2-199456. However, the type of decorative material that forms a pattern on the surface, depending on the shape, there is no sense of depth, or partial vermicular patterns such as when polishing the stone was sometimes difficult to form.

[0004]

SUMMARY OF THE INVENTION The present invention proposes, in addition to the above-mentioned invention, a method for easily producing a deep finish feeling and a finish of a natural stone polished finish pattern for a surface material.

[0005]

Means for Solving the Problems The surface covering material of the present invention basically has a decorative material portion, a base material portion, an adhesive material portion, and a release paper portion according to the invention of the prior application, and further includes a decorative material portion. It consists of a skin layer made of synthetic resin film to cover. However,
The main parts are three layers of a skin layer, a decorative material part and a base material part. Hereinafter, the covering material of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an external appearance of a covering material according to an embodiment of the present invention. In the figure, a skin layer, 2 is a decorative material portion, 3 is a base material portion, 4 is an adhesive material portion, and 5 is a release paper portion. 3, 4, and 5 are front views, rear views, and FIG.
This is shown by a sectional view taken along the line A '. FIG. 2 shows an example of a method of forming the base portion, the decorative material portion, and the skin layer, which are main portions. 2A is a sectional view showing a state in which the decorative material portion 2 is obtained by spray-coating three-colored multi-color paints 10a, 10b, and 10c on the base material portion 3 at the same time. FIG. 2B is a cross-sectional view showing a state in which the cosmetic material portion of FIG. 2A is partially flattened by pressing or polishing when it is not cured. Further, (c) in FIG. 2 is a cross-sectional view showing a state in which a skin layer made of a synthetic resin film is integrated on the decorative material portion while making use of the unevenness in the state (b). In addition, about the formation method of the decorative material part 2 on the base material part 3, it can produce by means of spraying and dripping other than spray coating. Further, in the example of FIG.
The skin layer 1 is formed while making use of the irregularities. However, it is desired to apply various paints so as to be flat and to use a press die having an irregular pattern in a stage of integration with the skin layer. It can also be uneven or flat.

In order to use the base material, the decorative material, and the skin layer prepared as described above to form a surface covering material, one joint / overlap portion is formed in the base material. This can be achieved by curing when applying a colorful paint or the like for forming a decorative material portion on the base material portion. Further, in order to form the adhesive portion 4 and the release paper portion 5 on the back surface of the facing material, a double-sided adhesive sheet in which the adhesive and the release paper are combined may be cut and adhered, or the adhesive material may be applied and separated therefrom. It is also possible by attaching a pattern.

[0007] Respective members constituting the facing material of the present invention will be described below. As the material of the base member 3, there are nonwoven fabric, glass cloth, ceramic paper synthetic paper and the like. A flexible paint may be applied to the surface or both surfaces of these materials for coloring. The decorative material section 2 is made by molding natural stone or its crushed stone, colored aggregate, colored plastic particles, and plastic crushed particles with a synthetic resin emulsion, a solvent-type synthetic resin, a hot-melt resin, or the like, or spraying for construction. In this way, a paint film can be formed and used as a decorative material portion. Regarding the composite of the decorative material part on the base material part,
Alternatively, it can be done by painting.

The first material of the synthetic resin film forming the skin layer 1 is transparent and thermoplastic, but in consideration of practical use, it has other dimensions such as dimensional stability, elongation, weather resistance, and ultraviolet shielding. It is necessary to have heat resistance, heat resistance, scratch resistance, water resistance, alkali resistance, and acid resistance.
As a usable material, an acrylic resin, a vinyl chloride resin, a polyester resin (a typical example is polyethylene terephthalate) or the like can be used. The thickness of this film can be about 10 μm to 1 mm, but 100 to 200 μ is appropriate in consideration of bending.

Next, the adhesive part 4 on the back surface of the base part 3
It is necessary to be narrower than the previous joint and margin part,
The position to be adhered is the side opposite to the side where the joint and overlap allowance are provided in the surface material, and as the material, an acrylic rubber-based or non-vulcanized butyl rubber-based material is particularly good. Silicone rubber, styrene butadiene rubber, polyisoprene, polyvinyl ether and the like can be used. The release paper part 5 is made of a known material that is generally used for an adhesive tape, a label, or the like.
What is necessary is just to use a material coated with a silicone resin. In order to easily form the adhesive portion and the release paper portion, a commercially available double-sided adhesive tape can be cut and attached.

EXAMPLES In the examples, first, a decorative material portion was formed with various paints on a base material which was cured around the decorative material portion, and a skin layer was integrated therefrom. In the base part 3 of Example 1, a sheet was prepared by coating a dark gray acrylic resin paint on both sides of a polyester nonwoven fabric with a knife coater. Cosmetic material part 2 is a paint 1, a paint 2, a paint 3, which is a combination of a combination paint composition 1 in Table 1 below and an aggregate composition 1, 2 and 3 in Table 2 on one surface of base material 3. At the same time by spraying.
The average thickness of the base material and the decorative material was 4 m.
m. After this was dried, an MMA film, which is a kind of acrylic resin, having a thickness of 200 μm was used for the skin layer, and the skin layer was pressed in a painted shape without air.

[Table 2]

In the second embodiment, after applying the three colors of the paint in the first embodiment, the roller is pressed immediately after the application by a roller so that a part of the recess remains. Then, the MMA film having a thickness of 20 m
0 μm was pressed.

In the third embodiment, the three colors of the paint of the first embodiment are prepared by the paint formulation 2 having improved leveling properties shown in Table 3 below with the same aggregate formulation, and the base material of the first embodiment is used. Then, it was painted on this. At this time, the average thickness of the base and the decorative material was 3.5 mm. Next, a 150 μm-thick MMA film serving as a skin layer was pressed and pressed while applying porcelain tile-shaped irregularities to a press mold.

[0015]

[Table 3]

In preparing the facing material, the size of the decorative material portion was set to 40 × 60 cm, and the joint / overlap portion was provided on two adjacent sides of the decorative material portion in a width of 5 cm.
Then, on the back surface of the base material portion, an adhesive material portion and a release paper portion were provided on two sides facing the joint / overlapping portion. The adhesive portion and the release paper portion were formed by laminating a non-vulcanized butyl rubber sheet having a thickness of 0.2 cm and a width of 4.5 cm.

To confirm the workability, 600 pieces of surface covering materials prepared by the method of Example 3 were manufactured and constructed on a 2 m-high wall made of concrete block, and the workability and fit were confirmed. As an adhesive at the time of construction, a polymer cement shown in the adhesive composition in Table 4 below was used. As a result of the construction test, it was possible to construct about 50 m ² per person per day, and the settlement was good. In particular, the surface covering material stretched to the corners of the block had a beautiful natural stone-like finish with no cracks and no gloss problem.

[0019]

By applying the surface covering material of the present invention to the outer surface of the outer wall of a building, it is possible to achieve a waterproof construction with good fit. That is, conventionally, when a sheet-like surface covering material is applied to the outer surface of the outer wall of a building, since there is no overlapping portion, the adhesive applied to the base material protrudes from between the sheets, so that a beautiful finish is obtained. Did not. Further, in order to consider waterproofness, a sealing treatment between the sheets was required. However, by applying the surface covering material of the present invention, the adhesive does not protrude from between the sheets, and the sealing treatment between the sheets is not required. In addition, the overlap which is colored to a desired joint color and also serves as a joint is provided. By exposing the allowance with a certain width, it is effective in design as a cosmetic joint. Further, the surface covering material of the present invention is safe even against rainfall immediately after construction.

Further, in the surface covering material of the present invention, by providing the skin layer on the molded product or the coating film, the resistance to scratches can be increased, and the appearance can be given depth. In addition, conventionally, a transparent paint was sometimes applied in order to give a luster, but this step was also replaced.
