Description

Description: TECHNICAL FIELD The present invention relates to a covering material that can be applied to inner and outer wall surfaces of buildings, floor surfaces, and the like, and a finishing method therefor, and the field of use thereof is the building field. .

(Prior Art) Conventionally, as a sheet-shaped surface covering material, there is a wallpaper for interior of a building, but this has not taken into consideration the durability when used outdoors.

As a sheet-like surface covering material which is considered to be applied to the outer surface, there are inventions disclosed in JP-A-59-106660 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 (flameproof member). Further, the invention described in JP-A-59-106660 discloses that the mesh base material is embedded in the base plate so that the base plate and the imitation tile surface are made of different or different color coating materials. Was formed.

(Problems to be Solved by the Invention) JP-A-59-106660 or JP-A-63-63 in the prior art.
In the invention described in the publication of -125332, although a material that can be applied to the exterior surface of the outer wall is selected, even if there is no problem if it can be covered with a single sheet, especially considering waterproofness and storage Since it is not, the joint between the seats has not been solved and it was not practical. An object of the present invention is to provide a seat in which joints between the seats are made easy in consideration of waterproofness and storage.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the covering material according to the present invention, the sheet is formed into a substantially rectangular shape, and the adjacent two sides have two overlapping portions also serving as joints. And the back surface of the other two sides is coated with an adhesive material.

The covering material of the present invention will be described with reference to the drawings. Figure 1 shows
It is a front view of an example cover material. In the figure, 1 represents a decorative material portion, and 2 represents a base material portion that supports the decorative material portion. FIG. 2 is a view in which a part of the surface material is cut away from the back surface, and the adhesive material 3 adhered to the back surface of the base material portion and the release paper portion 4 covering the adhesive material can be seen. FIG. 3 is a sectional view taken along the line AA ′ in FIG. As shown in the figure, a decorative material portion is formed on the base material portion 2 excluding the joint / overlap margin, and the adhesive material portion 3 and the release paper portion covering the adhesive material portion 3 are formed on the back surface of the side of the covering material having no overlap margin. 4 has been formed.

It is preferable that the base material portion 2 is sufficiently thinner than the decorative material portion 1 and has a thickness of 2 mm or less. Further, the width of the portion which serves as both the joint and the overlap margin is preferably 20 to 100 mm so that the overlap margin can be sufficiently secured and the adhesive area when secured on the outer surface of the outer wall is secured.

Suitable materials for the base material include non-woven fabric, glass cloth, ceramic paper, and synthetic paper.

The decorative material part 1 is preferably made by molding natural stone, crushed stone thereof, colored aggregate, colored plastic crushed particles with synthetic resin emulsion, solvent type synthetic resin, hot melt resin, etc. You can also use what you did. In addition, the building material can be made into a decorative material part by coating the material on the base material.

The composite of the decorative material portion on the base material portion can be performed by bonding to a portion excluding the joint / overlap portion or painting.

Next, the adhesive material portion on the back surface of the base material portion 2 needs to be narrower than the previous joint / cumulative margin portion, and the position to be adhered is the side where the previous joint / cumulative margin is provided in the covering material. It is the side opposite to the above, and as its material, acrylic rubber type or non-vulcanized butyl rubber type is particularly preferable, and silicone rubber type, styrene butadiene rubber type, polyisoprene type, polyvinyl ether type, etc. are also used. it can.

The release paper may be a known material that is usually used for adhesive tapes, labels, etc., and in particular, one coated with a fluororesin 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, etc., there is no up and down on the floor surface, so it suffices to start from any corner, but on the wall surface, there is usually no joint and overlap margin from below. With the same as the upper and lower sides shown in FIG. Various adhesives such as synthetic rubber, vinyl acetate, polymer cement and acrylic rubber can be used as the adhesive for adhering the surface material to the wall surface. In pasting, the adhesive is protected by a release paper while the joint width is opened or the joint is not taken, and the release paper is peeled off to adhere the overlapping portion. When considering the waterproof property, start sticking from the bottom of the wall surface and stick it upwards, so that the joint and overlap margin part of the lower sheet is
Prevent the entry of rainwater etc. by making it under the adhesive part of the upper sheet. FIG. 4 shows an external perspective view in the middle of construction in this way. In the example shown in this figure, first, allocation is performed according to the size of the covering material, and the parts are jointed in order from the bottom so that the joint / overlap margin portion appears in the table. FIG. 4 shows a state where the second step from the bottom is attached and the third step from the bottom is started.

(Example) In an example, a covering material according to the present invention was manufactured and a construction test was conducted. In the surface covering material in the examples, a sheet in which both surfaces of a polyester non-woven fabric were coated with acrylic resin paint by a knife coater was used as the base material portion 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 Working Formulation 1 by spraying. The dimensions of the cover material are 40 cm x 60 cm.
And the joint and stacking allowance is 5 cm with the coated non-woven fabric exposed.
Width Adhesive 3 and release paper are 0.2mm thick and 4.5 wide
A non-vulcanized butyl rubber sheet made into cm was used. We manufactured 600 sheets of such covering materials and constructed them on a concrete block structure with a height of 2 m, and confirmed the workability and fit. As the adhesive material at the time of construction, polymer cement shown in the following practical combination 2 was used. As a result of the construction test, it was possible to construct about 50 m ² per person, and the installation was good.

Working composition 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 100 parts by weight Working composition 2 Portland cement 20 parts by weight Mineral fiber 2 parts by weight Sand 50 parts by weight Acrylic synthetic resin emulsion 15 parts by weight Water 13 parts by weight Total 100 parts by weight (Effect of the invention) By applying the surface covering material of the present invention to the outer surface of the outer wall of a building, the waterproof property is good and Good construction is possible. 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 part, the adhesive applied to the base will stick out from between the sheets, resulting in a beautiful finish. There wasn't. Also,
In order to take waterproofness into consideration, a sealing treatment was required between the sheets.

However, by applying the cover material of the present invention, the adhesive material does not protrude from between the sheets, and the sealing treatment between the sheets becomes unnecessary. In addition, by exposing the overlap margin, which also functions as a joint and is colored in a desired joint color, with a constant width, it is effective in terms of design as a makeup joint.
Further, since the covering material of the present invention is completely waterproof immediately after construction, it is safe even against rainfall immediately after construction.
