Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a decorative material for finishing a building surface, which is used for decorating the interior or exterior wall surface or floor surface of a building. In particular, it relates to a decorative material for finishing the surface of a building, the surface of which is covered with a release sheet.

[0002]

[Prior art]

 Spraying materials such as synthetic resin emulsions and aggregates such as marble powder, silica sand, ceramic powder and other aggregates and colored aggregates such as colored silica sand and colored ceramic powders with a chilled gauze and other suitable relatively coarse synthetic fibers A natural stone-like product obtained by applying it to a woven fabric or an appropriate solid substrate by an appropriate method such as spraying, drying, and optionally applying a transparent synthetic resin top coat layer and cutting it to an appropriate size. The decorative material with the pattern is used as a sheet for finishing the surface of a building, such as for decorating interior and exterior walls or floors of a building. (JP-A-4-76151, JP-A-3-279561).

As a decorative material for a building surface finish, a split skin pattern, a yuzu skin pattern (rippled pattern), a jelly pattern, a wood grain pattern, and Japanese Patent Laid-Open No. 57-27177 are used depending on the uneven shape and pattern of the surface state. Sheets for finishing surfaces of buildings such as cast-like patterns, travertine-like patterns, natural sandstone patterns, natural granite patterns, tiles, etc. As a sheet-shaped decorative material, a surface pattern very similar to natural stone or other appropriate artificial surface irregularity pattern is used.

Natural stones such as marble, sandstone with a split skin pattern, and sedimentary rocks such as slate have a deeper and more profound feeling than before, and have been used as wall materials and floor materials for high-grade buildings. . In addition, various types of natural stones have been processed into various patterned surface states as described above, and have been used as wall materials and floor materials for high-grade buildings.

However, natural stone materials are extremely expensive, very heavy, and extremely costly to carry. Moreover, since they are heavy, it is difficult to work at high places, for example. Depending on how it is handled, there are various problems such as dropping and impact, and damage such as inadvertent impact when the load is unloaded from the truck to the work site.

On the other hand, a spray material containing the above-mentioned synthetic resin emulsion and an appropriate aggregate such as marble powder, silica sand, ceramic powder or colored silica sand, colored ceramic powder, etc. is sprayed onto a cloth such as a sardine cloth or other suitable cloth-like sheet base material. Decorative materials that have been applied by an appropriate method such as attachment, or that have been given a natural stone-like pattern obtained by molding or other artificial patterns have a profound and deep appearance that is indistinguishable from natural stone. Or, it can be used as a decorative material for building surface finish, which is heavy, deep and high-quality with a desired unique pattern that is not natural, and is relatively inexpensive compared to natural rock. It is light in weight and advantageous in terms of transportation cost, and has the advantage of being easy to perform construction work even in high places, etc. It is often used as a sheet for business.

[0007] These are generally acrylic resin or other synthetic resin emulsions or solutions and application materials containing appropriate aggregates such as pearl stone powder, silica sand, ceramic powder or colored silica sand, colored ceramic powder, etc. The mainstream method was to spray it on or apply it with a trowel and then apply a transparent topcoat on top of it, if necessary. In order to express it, spraying materials of several kinds of colors are used with each spraying gun, or spraying materials of each color are sprayed onto the building while adjusting the spraying materials of each color from each nozzle of the two-headed gun or the three-headed gun. It is necessary to put it on and finish it to the texture of the desired pattern on site, and it is necessary to ripen it. In recent years, so that skilled workers do not have to go to the site and perform spraying while mixing, in the production plant, such coating materials can be sprayed with guns, trowels, etc. By applying it on a substrate such as synthetic fiber fabric with a relatively coarse mesh, drying it, and then applying a transparent top coat on it if necessary, and cutting it with a cutter to an appropriate size. After manufacturing the building surface finishing sheet in advance, it is then transported to the construction site and attached to the wall or floor surface of the building with an adhesive, etc., and the adjacent building surface finishing sheet and the sheet. It is becoming more and more common to apply a joint material to the gaps between the toes and finish the building more like a natural stone by applying a clean joint pattern.

[0008]

[Problems to be solved by the device]

 However, in order to apply a building surface finishing sheet that has been cut to a predetermined size to a building, such as when installing tiles, use a large number of building surface finishing sheets as described above. For example, it is necessary to provide a gap having an appropriate width of 5 to 20 mm and bond it to the surface of the building, and then apply a joint material to the elongated gap to give a joint pattern.

When such a joint material is applied to the joint, if the joint material is applied to the surface side of the building surface finishing sheet, the finish will be messy and the protruding joint material will be removed later. This is a problem because it requires removal work and repair. So, if there is no problem even if the jointing material squeezes out and is applied, an elongated paper adhesive tape is attached on site at the four edges on the surface side of the building surface finishing sheet (usually rectangular). Another method is to mask the area near the front side of the building surface finishing sheet, apply joint material, and then remove the adhesive tape. However, the work of sticking the adhesive tape to the four edges of the building surface finishing sheet exactly is very difficult because it is a lot of work, and since the adhesive tape made of paper is used, The work efficiency was not very good because it was difficult to stick along. In addition, since the building surface finishing sheet is transported by being carried to a construction site, a large number of building surface finishing sheets are stacked and transported by being placed on a truck, etc. There was also the problem of getting dirty.

The present invention solves the problems of these conventional products, makes it possible to efficiently apply a clean joint pattern at the construction site, and also has releasability that also protects the surface of the decorative material for building surface finish. The purpose is to provide a decorative material for finishing the surface of a building with a sheet.

[0025]

[Embodiment of device]

 Synthetic resin matrix, which is one of the constituent components of the decorative material for building surface finish of the present invention, usually uses a synthetic resin emulsion or a synthetic resin solution as a raw material. Various synthetic resin emulsions and solutions that have been conventionally used in the production of the decorative material for building surface finish can be used. Synthetic resin emulsions are preferably used because it is not necessary to consider the recovery of organic solvents and environmental problems. In particular, synthetic resin emulsions satisfying weather resistance, alkali resistance, water resistance, adhesiveness, flexibility, water absorption resistance, etc. are preferable. Specific examples include acrylic resin emulsions (acrylic resin emulsion, acrylic resin emulsion). -Styrene resin emulsion, acrylic-urethane resin emulsion, acrylic-silicone resin emulsion, acrylic-fluorine resin emulsion), vinyl acetate resin emulsion such as ethylene-vinyl acetate resin, vinyl chloride resin emulsion , Urethane resin emulsions and the like. The resin matrix after drying of any of these resins has suitable flexibility, and can be applied to a curved surface. Among them, acrylic resin emulsion is relatively inexpensive, and is particularly superior in terms of weather resistance, so it is used as a sheet for finishing building surfaces such as interior and exterior wall surfaces or floor surfaces of buildings. It is preferable because it has relatively long-term durability.

In addition, a transparent coat layer (usually a transparent coat layer) is usually provided on the surface side of the decorative material for the purpose of imparting functions such as providing gloss to the surface of the decorative material, preventing stains on the surface after construction, and enhancing waterproofness as necessary. (Referred to as "up coat"), any of the transparent top coat resins that are commonly used for decorative materials for building surface finishes of this type is used as the resin for the top coat. be able to. Among them, acrylic resin is one of the relatively inexpensive ones, which can satisfy various properties such as weather resistance, water resistance, and antifouling property, and therefore, it is necessary to form a top coat with relatively good durability on the surface of the decorative material. Is preferable because it can

Acrylic-silicone resins and acrylic-urethane resins are typical examples of acrylic resins for the top coat, and they are used in the form of their emulsions or organic solvent solutions.

[0028] Of course, it is not essential that the top coat is applied to all kinds of decorative materials for surface finishing of buildings, and in the case of finishing on the surface pattern of decorative materials that do not want to have too much surface gloss, Not used For example, topcoat may not be applied when a decorative material with a sandstone-like cracked surface unevenness is required due to the request of the contractor.

Although the thickness of the top coat layer is not particularly limited, it is usually preferably about 0.01 to 0.2 mm, more preferably about 0.05 to 0.15 mm. As the aggregate used as a constituent component of the decorative material for building surface finish of the present invention, various known aggregates used in manufacturing the decorative material containing the aggregate of this type can be used. Natural stones such as marble powder, granite powder, silica sand and other natural stone powders, ceramic powders, or artificially colored these, for example, so-called colored aggregates such as colored fired silica sand and colored ceramic powders. Fine particles, ceramic fine particles, or an inorganic material typified by an aggregate composed of at least one of these coloring matters is preferably used. Of course, aggregates made of organic materials such as plastics may be used, but aggregates made of inorganic materials such as those mentioned above may be more faded or discolored than aggregates made of organic materials such as plastics. It is preferably used because of its excellent durability and low cost.

As for the size of the aggregate, it is preferable to mainly use the aggregate having a size of 6 to 300 mesh. It is to be noted that the desired color tone can be obtained by appropriately combining one or two or more of artificially colored colored aggregates or aggregates of the same color as the raw material that is not artificially colored. The texture can be adjusted to make various decorative materials. It should be noted that the natural stone material does not actually mean only the same pattern and surface condition as the natural rock architectural decoration material, and it does not actually exist in nature, but it looks like It also means that it includes patterns, colors, and surface conditions as if they were natural stone.

In addition, synthetic resin colored flakes, other scale-like solid additives, and other additives may be added separately in order to give a unique texture if necessary. For example, as such a scale-like additive, one having a size of about 200 mesh to 1 cm ² is preferably used.

The blending ratio of the aggregate and the synthetic resin matrix varies depending on the kind and the texture of the decorative material, but the synthetic resin emulsion or solution is the resin solid content and the aggregate is the aggregate. About 5 to 20 parts by weight is preferable with respect to 100 parts by weight.

By adopting a preferred embodiment in this range, the aggregate can be firmly held by the synthetic resin matrix, and therefore, it is not too brittle, and is durable while maintaining a heavy and deep texture. A decorative material having strength can be obtained. If the amount of aggregate is too large, the proportion of the synthetic resin that also functions as a binder will be small, and the flexibility of the obtained decorative material will tend to decrease.On the other hand, if the amount of aggregate will be too small, it will be heavy. The deep texture tends to deteriorate.

The composition for forming a decorative material (coating material) in which an aggregate is mixed with a synthetic resin emulsion or solution may further include a filler, a film-forming aid, a thickener, a defoaming agent, if necessary. A pH adjuster or the like may be added, or water or an appropriate solvent may be added to reduce the viscosity.

For example, the filler is calcium carbonate, titanium oxide or the like, and the thickener is, for example, a methyl cellulose-based one (for example, “High Metroses 90SH-3000”, manufactured by Shin-Etsu Chemical Co., Ltd.), a film-forming aid. For example, butyl carbitol acetate and the like, as the defoaming agent, for example, “Nopcosanto NXZ” (manufactured by San Nopcosan Co., Ltd.), and as the pH adjusting agent, concentrated ammonia water and the like are preferably used. It is not limited.

In the decorative material of the present invention, the fact that a reinforcing base material is further laminated on the back side of the decorative material can increase the strength of the decorative material, and thus can provide a decorative material that is easier to handle. However, such a reinforcing base material is, for example, a reinforcing base material used in the production of a decorative material such as this kind of building surface finishing sheet which has been conventionally used. Can be used as well. Specifically, for example, a synthetic fiber woven fabric, more preferably a synthetic fiber woven fabric having a relatively coarse mesh, for example, a gauze coarsely woven fabric made of acrylic fiber or polyester fiber having no or little water absorption. Is preferred, and a gauze cloth made of acrylic fiber or polyester fiber is particularly preferred. It is preferable to use a non-absorbent or low-absorbent woven fabric because a highly absorbent fabric tends to expand due to water and contract easily during drying, which may cause warped or deformed products after drying. However, such a problem does not occur when a fabric having no water absorption or a small water absorption is used, which is preferable. In addition, plastic sheets, rubber sheets, metal sheets such as aluminum sheets and zinc-coated steel sheets are also used.

In the case of a soft decorative material, a cloth-like material is used as a reinforcement in that it does not impair its flexibility, and that it is easy to dry when the decorative material of the present invention has good air permeability and is dried. Knitted fabrics, non-woven fabrics, and the like can be applied as the cloth-like reinforcing substrate other than the woven fabric, which is useful as the base material. When a plastic sheet, a rubber sheet, or an expanded metal with many small holes is used, it is more advantageous in terms of drying, similar to the cloth-like material.

When laminating the reinforcing base material on the back side of the decorative material as described above, a spraying material for the decorative material for building surface finishing is sprayed or troweled on the reinforcing base material. Method is used. As one method to make uneven patterns for decorative materials for building surface finish appear, spray the spray material on the mold or plastic film or the female mold made of foam and fill the spray material with the trowel. In this case, it goes without saying that a method of laminating a base material on the spray material filled in a mold or the like and drying and solidifying the spray material may be employed before the spray material is dried and solidified.

When the reinforcing base material is laminated, it is also preferable that a spraying material or the like is thinly sprayed or applied from the back side of the reinforcing base material, because the reinforcing base material can be more firmly adhered. . Moreover, it is preferable to spray a spraying material thinly on at least the surface of the reinforcing base material, preferably both the front and back surfaces, and dry it beforehand, because the adhesiveness with the spraying material will be good. In some cases, the reinforcing material may be adhered to the back surface of the decorative material using an appropriate adhesive or the like after the spray material is dried and solidified to form the decorative material.

As the release sheet covering the surface of the decorative sheet for building surface finish used in the present invention, a flexible plastic film or plastic foam sheet having an adhesive coated on the back side is used. To be If a relatively rigid sheet is used instead of a flexible plastic film or a plastic foam sheet, and if the decorative sheet for building surface finish has an uneven pattern, the uneven pattern on the decorative sheet surface The release sheet is too easy to peel off and fall off because there are too many gaps to open along the edges, and the adhesion to the decorative sheet for building surface finish is too poor and the edges are When the joint material is applied and the gap is too open, the joint material that protrudes enters the gap between the decorative sheet for building surface finish and the releasable sheet, and the decorative material for building surface finish. It is not preferable because it may stain the surface of the sheet.

From such a point of view, it is preferable to use a relatively flexible release sheet, and it is applicable to a case where the decorative sheet for surface finishing of a building is a sheet having an uneven pattern. Select a material that has flexibility, and if the thickness is thick, use it with a thickness that provides flexibility. It is preferable to use a release sheet.

From this point of view, as the material of the plastic film, polypropylene film, polyethylene film, polyester film, polyvinyl chloride film, polyvinylidene chloride film, polystyrene film and the like are preferably used. Although different, the thickness of the plastic film is preferably 0.03 mm to 0.5 mm. If it is too thick, it will be difficult to follow the uneven pattern of the decorative material, and if it is too thin, the strength will be weak and the protective function will be low in terms of surface protection. In particular, the use of unstretched film is preferable because it does not have a relatively high rigidity and easily follows the uneven pattern of the decorative material.

When using a plastic foam sheet, a polypropylene foam sheet, a polyethylene foam sheet, a polyester foam sheet, a polyvinyl chloride foam sheet, a polyvinylidene chloride foam sheet, or a polystyrene foam sheet. And the like, and the thickness of the plastic foam sheet is preferably 0.5 mm to 2 mm, though it depends on the type of the material. If it is too thick, it will be difficult to conform to the uneven pattern of the decorative material, and if it is too thin, the strength will be weak and the protective function will be low in terms of surface protection. In particular, when a plastic foam sheet having a bulk density of 0.07 to 0.2 g / cm ³ is used, the rigidity is not relatively high, and it is preferable because it easily follows the uneven pattern of the decorative material.

Particularly, a polyethylene film or a polyethylene foam sheet is preferable from the viewpoint of being relatively inexpensive and having excellent flexibility and easily conforming to the surface uneven pattern of the decorative material.

An adhesive material is applied to the back side of a release sheet made of these flexible plastic films or plastic foam sheets. Any adhesive may be used as long as it does not deteriorate the decorative sheet for building surface finish, and various adhesives used for ordinary adhesive tapes can be used. The most popular adhesive is an acrylic pressure-sensitive adhesive, but other rubber-based pressure-sensitive adhesives, silicone-based pressure-sensitive adhesives, and the like are also included, but are not limited thereto.

The coating thickness of the pressure-sensitive adhesive to be applied is not particularly limited, and may be a thickness generally used for ordinary pressure-sensitive adhesive sheets, adhesive tapes and the like. If numerical values are dared, it is generally about 30 to 500 g / 25 mm according to the JIS Z0237 test method.

The decorative material for building surface finish with a release sheet according to the present invention can be used as a decorative material for building surface finish of a size smaller than a predetermined size or, for example, a very long length. A decorative sheet for building surface finishing was prepared, and a releasable sheet consisting of a plastic film or plastic foam sheet coated with an adhesive on the back side was placed on the surface of the building finishing material. Adhere with a size that completely covers the side, create a decorative material for building surface finish with release sheet, then cut this with a cutter to a predetermined size (usually a square shape) Although it is cut, it is particularly preferable that it is cut by inserting cutting teeth in the thickness direction from the plastic film or plastic foam sheet side. This is because when the flexible plastic film or plastic foam sheet is cut, it is stretched and cut slightly at the edge surface, so the edge of the edge of the cut plastic film or plastic foam sheet is cut. Wraps around the edge surface side of the decorative material for building surface, and the release sheet firmly adheres to the decorative material for building surface at the edge part. There is a gap between the formability sheet and the surface of the decorative material for building surface finish, and when the joint material is applied, it is more likely that the joint material will enter through this gap and stain the surface of the decorative material for building surface finish. It is estimated that it can be surely prevented. Also, compared to the case where the release sheet and the decorative material for building surface finish are not attached to each other and are cut to the required size in advance and then the both are attached, the release sheet is used. It is not necessary to align and bond the surface of the decorative material for building surface finish with each other, and it is very efficient in terms of work and is preferable. Also, when cutting with such a flexible plastic film or plastic foam sheet side with a cutter, as described above, when the flexible plastic film or plastic foam sheet is cut, the edge surface may be slightly cut. The cut edge of the stretched and cut plastic film or plastic foam sheet slightly wraps around the edge side of the decorative material for building surface finish, and the release sheet is firmly constructed at the edge. Since it adheres closely to the decorative material for surface finishing, the plastic film or foam sheet can be fixed on the surface of the decorative material for building surface without applying adhesive to the back side of the plastic film or plastic foam sheet. You can also do it. However, if the adhesive is applied, the plastic film or plastic foam sheet may be peeled off from the building surface finishing decoration material once if necessary, and then the building surface finishing decoration material may be removed. When it is desired to adhere to the surface of, it is possible to re-adhesive, which is preferable. In addition, it is more preferable to apply an adhesive in that the release sheet is not likely to peel off when it is not intended.

The manufacturing method by cutting described above is a preferable method, but of course the present invention is not limited to the one obtained by this method, and the release sheet and the decorative material for building surface finish can be used. It is also possible to cut each to a required size in advance without pasting and then to attach both.

The decorative material for building surface finish with a releasable sheet cover thus obtained is transported to a construction site where the releasable sheet is attached to the construction site, and then the wall or floor of the building For example, by applying the joint material to a predetermined place with a gap between the joints and applying the joint material to the joint portion, which is the gap between the adjoining decorative materials for building surface, as described above, peel off the release sheet. As a result, it is possible to easily apply a decorative material for the surface finish of a beautiful building that is free from dirt due to the joint material protruding.

Next, in order to facilitate understanding of the present invention, FIG. 1 is a schematic cross-sectional view showing an example of a manufacturing process of a decorative material for surface finishing of a building with a release sheet of the present invention, and FIG. An example of a process for constructing a building using the decorative material for finishing the surface of the building with a release sheet according to the present invention will be shown and described. Of course, the present invention is not limited to the illustrated one.

As shown in FIG. 1 (a), the main part of the decorative material for building surface finish of the present invention is placed on an appropriate reinforcing base material 1 such as a garment cloth made of acrylic fiber or polyester fiber. The synthetic resin emulsion or synthetic resin solution that is the raw material for the constituents that make up the parts By drying, a sheet 4 having an aggregate 2 dispersed in a synthetic resin matrix 3 and having an uneven pattern on the surface was prepared, and further, a top coat layer 5 made of a transparent synthetic resin was applied to the surface, if necessary. A sheet of the decorative material 6 for building surface finish is created.

Next, as shown in FIG. 1 (b), a flexible plastic film or plastic foam in which an adhesive 8 is applied to the upper surface of the sheet of the building surface finishing material 6 on the back side. A releasable sheet 9 composed of the sheet 7 is attached to form a decorative material 6 for building surface finish with the releasable sheet. At this time, if the surface of the decorative material 6 for building surface finish has unevenness, it is preferable that the release sheet is adhered along the unevenness of the surface as much as possible, but there is a part that is not adhered. Also, there is no problem as long as the object of the present invention can be achieved.

Next, as shown in FIG. 1C, the release sheet 9 is cut into a predetermined size with a cutter 10 from above. When the releasable sheet 9 made of the flexible plastic film or the plastic foam sheet 7 is cut, the edge surface is slightly stretched and cut, so that as shown in FIG. Since the edge of the cut film or foam sheet slightly wraps around the edge side of the decorative material sheet (the part slightly wrapping around the edge side of the release sheet 9 is shown as 11). ) At the edge part, the release sheet firmly adheres to the decorative material for finishing the building surface, and at the edge, between the edge of the releasing sheet and the edge of the decorative material for finishing the building surface. (EN) A decorative material for finishing a building surface in which no gap is generated.

Next, as shown in FIG. 2A, the decorative material 6 for building surface finish with the releasable sheet 9 having a desired size obtained in FIG. The space 12 necessary for providing an appropriate joint pattern on the surface of the building 12 to be formed is opened and an adhesive 15 is applied.
