In together with PREFERRED EMBODIMENTS drawings, the face material of the present invention
An example will be described. FIG. 1 is a front view of an example of a facing material. In the figure, reference numeral 1 denotes a decorative material portion, and reference numeral 2 denotes a base material portion supporting the decorative material portion. FIG. 2 is a partial cutaway view from the back surface of the front cover material. The adhesive portion 3 adhered to the back surface of the base portion and the release paper portion 4 covering the adhesive portion 3 can be seen. FIG. 3 is a sectional view taken along line AA ′ in FIG. As shown in the figure, a decorative material portion 1 is formed on a base material portion 2 except for a joint and overlap allowance, and an adhesive material portion 3 and a release paper covering the adhesive material portion 3 are provided on the back surface of the side of the facing material having no overlap allowance. The part 4 is formed.

[0007] The base member 2 is preferably sufficiently thinner than the decorative material 1 and 2 mm or less. In addition, the width of the portion serving as the joint and overlap margin is 20 to 10 when the overlap margin is sufficiently removed and the bonding area when applied to the outer surface of the outer wall is ensured.
0 mm is appropriate. Suitable materials for the base 2 include nonwoven fabric, glass cloth, ceramic paper, synthetic paper, and the like.

[0008] The decorative material section 1 is made of natural stone, its crushed stone, colored aggregate, and colored plastic crushed granules.
Those molded with a solvent type synthetic resin, hot melt resin or the like are suitable, but stainless steel or aluminum thin plates or those coated thereon can also be used. In addition, a decorative material portion can be obtained by painting a spraying material for construction on a base material.

The composite of the decorative material portion 1 on the base material portion 2 can be achieved by bonding to a portion other than the joint and overlap margin portion, or by painting. Next, the adhesive material portion 3 on the back surface of the base material portion 2 needs to be narrower than the previous joint / overlap portion, and the position to be adhered is provided with the previous joint / overlap portion in the surface material. The side opposite to the side is preferably made of acrylic rubber or non-vulcanized butyl rubber. In addition, silicone rubber, styrene butadiene rubber, polyisoprene, polyvinyl ether, etc. Available.

The release paper constituting the release paper section 4 is:
A known material usually used for an adhesive tape, a label, or the like, in particular, a material coated with a fluorine resin or a silicone resin may be used. When attaching the surface covering material of the present invention to the inner and outer wall surfaces, the floor surface, and the like, the floor surface does not have any up and down, so it is sufficient to start attaching from an arbitrary corner. , And the adhesive is also used and attached together, for example, in the same manner as the top and bottom shown in FIG. Various kinds of adhesives such as synthetic rubber, vinyl acetate, polymer cement, and acrylic rubber can be used as the adhesive for bonding the surface material to the wall surface or the like.

[0011] At the time of sticking, the adhesive portion protected by release paper is adhered while laminating the joint width while opening the joint width or without the joint, and then the release paper is peeled off and the overlapped portion is adhered. . When considering waterproofness, start attaching from the lower part of the wall surface and attach it to the upper part, so that the joint and overlap margin of the lower sheet are under the adhesive part of the upper sheet, so that rainwater etc. Prevent intrusion.

FIG. 4 is a perspective view showing the appearance during the construction in this way. In the example shown in this figure, the layout is first performed in accordance with the size of the surface covering material, and the joints and overlapping allowance portions are sequentially applied from the bottom so that the joint and overlap margin portions appear in the table. FIG. 4 shows a state in which the second stage from the bottom is applied and the third stage from the bottom is started.

[0013]

EXAMPLES In Examples, a surface covering material according to the present invention was manufactured and a construction test was performed. In the surface material in the embodiment,
A sheet in which an acrylic resin paint was coated on both sides of a polyester nonwoven fabric with a knife coater was used as a base member 2.

The decorative material portion 1 was formed by curing a joint / overlap portion and the like on one surface of the base material portion 2 and applying a paint according to the following formulation 1 by spraying. The dimensions of the surface covering material were 40 cm × 60 cm, and the joint and overlap margin was 5 cm wide by exposing the coated nonwoven fabric. For the adhesive part 3 and the release paper part 4, a non-vulcanized butyl rubber sheet having a thickness of 0.2 mm and a width of 4.5 cm was used. 600 such surface materials
The pieces were manufactured and constructed on a 2 m high fence made of concrete blocks to confirm workability and fit. As an adhesive at the time of construction, a polymer cement shown in the following Example 2 was used.

The result of the construction test is about 50 per person.
Construction of m ² are possible, were better fit. (Example blend 1) Acrylic synthetic resin emulsion 25 parts by weight Colored fine aggregate 60 parts by weight Additives such as thickener 5 parts by weight Water 10 parts by weight Total 100 parts by weight (Example blend 2) Portland cement 20 parts by weight mineral fiber 2 parts by weight Silica sand 50 parts by weight Acrylic synthetic resin emulsion 15 parts by weight Water 13 parts by weight Total 100 parts by weight

[0016]

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 becomes unnecessary. In addition, by exposing the overlapping margin, which is also colored as a desired joint color and also serves as a joint, with a certain width, it is effective in design as a cosmetic joint.

Further, since the surface covering material of the present invention has complete waterproofness immediately after construction, it is safe against rainfall immediately after construction.
