BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a decorative sheet for surface finishing of a projected corner.

[0002]

2. Description of the Related Art In recent years, a sheet-like decorative material has been widely used as a decorative material for finishing the interior or exterior of a structure such as a building or the surface of a floor.

When a decorative sheet for surface finishing is attached to the interior or exterior of a building or the like, the projected corner of the building or the like is used as a finishing method as shown in, for example, JP-A-6-264593. The outline is shown in FIG.
Explaining with reference to (d) (all are sectional views),
Attached to the two surfaces that make up the projected corner 2 of the building 1 2
For example, each of the sheets of surface-finishing decorative sheets 100a and 100b (both consisting of the base material 101 and the decorative material 102) has a half angle (90 ° in this case) of the projected corner 2 (in this case, 90 °). The end portions of the surface-finishing decorative sheets 100a and 100b are scraped off by, for example, a sander 105 so as to form a taper of 45 °) so that they are along the projected corner when the two are abutted (see (a) of FIG. 15). The end portion is offset by several mm in the thickness direction of the surface finishing decorative sheet and attached to the projected corner portion (see (b) and (c) of FIG. 15), and the protruding portion is scraped off with, for example, the sander 105 ( Figure 1
5 (see (d)) method is shown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a process diagram showing a preferred embodiment of a method for producing a decorative sheet for surface finishing of a projected corner portion of the present invention, and a schematic cross-sectional view showing the production-construction process also showing the construction process thereof.

As shown in FIG. 1 (a), the base portion 4 coated with the adhesive 3 and the inclined flat surfaces 8a and 8b which protrude from the middle of the base portion 4 and spread to the left and right, An angle α formed between the left and right inclined planes is approximately (180 degrees-angle of the projected corner), and a partition member 6 including a partitioning bar 5 for forming a taper portion having releasability (this partitioning member is shown in FIG. 2). 6 is shown in a perspective view of FIG. 6) on both sides of the base portion 4 of the decorative sheet for surface finishing 11a, 11 respectively.
b is placed so that its end portion is almost in contact with the hem ends 7a and 7b of the partition rod 5, and the vicinity of the end portions of the base materials 11a and 11b are adhesively fixed on the base portion 4 (see FIG. )), And then the cosmetic material is sprayed from above with a spraying gun or the like, or is applied using a trowel or the like and dried and solidified to form the cosmetic material 12 (see FIG. 1 (c)),
The decorative material 12a formed near the tip of the partition rod 5 is scraped off with a sander or the like (see FIG. 1 (d)), and the decorative sheet 13 for surface finishing of the projected corner portion (however, with the partition member 6) is obtained. . Depending on the material (releasing property) of the partition bar 5 and the angle formed by the left and right inclined planes, a part such as a raised decorative material 12a may not be formed near the tip of the partition bar 5, or the decorative material 12a may be formed. When the coating is applied so that such a portion is not formed, the work of scraping off the portion such as the decorative material 12a can be omitted. Although not particularly shown, except for the edges 14a and 14b of the tapered portion,
The other three sides are cut into a required size by a cutter as needed. In addition, at least the inclined planes indicated by 8a and 8b of the partition rod 5 and the surface in contact with other decorative materials need to have releasability from the applied and dried and solidified decorative material. . Usually, it is preferable to ship the product at this stage or transport it to the construction site. This is because if the partition member 6 is removed as shown in FIG. 1E, the edge portions 14a and 14b of the sharp taper portion may be damaged during transportation work such as loading, transportation, and unloading. However, in the state shown in FIG. 1D, since the edge portions 14a and 14b are not exposed, there is no possibility of being damaged during normal carrying work. Then, it is transported to the construction site and the partition member 6 is removed immediately before the construction as shown in FIG. As described above, the partition bar 5 has releasability from the applied and dried and solidified material, and the base materials 11a and 11b are adhered to the base portion 4 of the partition member 6 by the adhesive material 3. Since it is only temporarily fixed, the operator can easily remove it at the construction site immediately before construction. Then, an appropriate adhesive is applied to the exposed tapered surfaces 15a and 15b and the back surfaces of the base materials 11a and 11b, and as shown in FIG. Decorative sheet 13 for surface finishing on the wall,
13 is bonded and the construction is completed.

In the method of manufacturing a decorative sheet for surface finish of the present invention, the taper portion can be accurately and uniformly formed by the partition rod 5, so that the edge of the projected corner portion (projected corner line) is finished sharply and beautifully. be able to.

In the above example, the base portion 4 coated with the adhesive and the partition rod 5 are used together (these are collectively referred to as partition member 6). 4 is not always necessary, the partition bar 5 is used alone, the partition bar is placed on a workbench having releasability, and the base materials 11a and 11b are brought into contact with both hems of the partition bar.
Alternatively, a simple method of arranging and applying a cosmetic material raw material on it by an appropriate means such as spraying may be employed.

The partition rod may be made of any material as long as it can withstand coating and drying and solidification of the cosmetic raw material, and is not particularly limited. For example, various plastics and metals are generally used. When it does not have releasability for the decorative material (for example, vinyl chloride resin, polystyrene resin, steel, etc.), the above-mentioned 8a, 8
A release agent may be coated on the b-side, and if it is made of a polyolefin resin such as polyethylene or polypropylene, polyester resin, fluororesin, silicone resin, or other synthetic resin having good release properties. Since the material itself has releasability, it is not necessary to apply a release agent to the surface, which is preferable. Among them, polyethylene and polypropylene are preferable materials because they are relatively inexpensive and have necessary strength and water resistance. Further, the partition rod may be a rod-shaped one in which the material is filled up to the inside, may be hollow, may be a foamed material in some cases, and may be molded using a plate-shaped material.

The partition bar shown in FIG. 1 (a) is
The cross section is a normal triangular shape, but the cross sectional shape is not limited to a triangular shape, and if it has at least sloping flat surfaces 8a and 8b extending to the left and right, for example, the trapezoidal shape shown in FIG. Other shapes, such as a mountain shape with rounded vertices shown in FIG. In this case, the left and right inclined planes 8a, 8
The angle at which b intersects is "the angle formed by the left and right inclined planes", and it must be approximately (180 degrees-the angle of the projected corner).

Further, as the sectional shape of the partition rod, it is more preferable to use, for example, a partition rod having a widened portion in which the vicinity of both hem portions thereof further spreads outward. A few specific examples of the partition bar having a widened portion in which the vicinity of both hem portions further spreads outward are shown in the sectional views in FIGS. 5 to 10. The partition bar shown in FIGS. 5, 7 and 9 has a widened portion 20 in which the vicinity of both hem portions is further linearly expanded outward.
It is sectional drawing of the partition rod which has a, 20b. The partition rod shown to FIG. 6, FIG. 8, and FIG.
It is sectional drawing of the partition bar which has b. In the manufacturing process shown in FIG. 1, the partition bar 5 shown in FIG. 1 is replaced with a partition bar 5 as shown in FIG. When the sheet is manufactured, as shown in FIG. 11, when the obtained decorative sheet for surface finish is applied to the projecting corner portion 2 of the building 1, an excessively accumulated pool 21 of the adhesive is applied. It is preferable that the extra adhesive agent is accumulated in the area and the adhesive agent does not stick out to the outside, and the projected corner line can be finished neatly. The shape of the spread portion is not limited to the shapes shown in FIGS. 5 to 10 as long as the object of the present invention is not impaired. Further, the partition bar having the two spread portions 20a and 20b near both hem portions is illustrated, but only one spread portion is provided at one hem (the other hem has no spread portion). Of course, partition bars may be used and are included in the method of the present invention.

The material of the base portion 4 in the case of adopting a partition member that uses both a partition rod and a base portion is not particularly limited, and a sheet-shaped or film-shaped material is used,
There is no particular limitation as long as a pressure sensitive adhesive such as a plastic sheet, a plastic film, a metal sheet, a metal plate, a knitted fabric, a woven fabric, a non-woven fabric, paper, or a glass cloth can be applied thereon. For convenience, a wide range of commercially available adhesive tapes is usually cheap.

The partition member may be a combination of the partition rod 5 and the base portion 4 coated with the adhesive 3 as described above, which may be used in combination, but the partition rod 5 and the base portion may be used. It is also possible to use a partition member in which 4 and 4 are integrally molded, and the adhesive 3 is applied on the base portion 4.
Cross-sectional views of specific examples of such integrally formed partition members are shown in FIGS. 12, 13 and 14. The example shown in FIG.
When the partition rod 5 has a cross-sectional shape of an isosceles right triangle, the example shown in FIG. 13 shows that the cross-sectional shape of the partition rod 5 is further outward in the vicinity of both hem portions as shown in FIG. This is an integrally-molded product of a type corresponding to a partition bar having linearly expanded spreading portions 20a and 20b, and FIG. 14 shows that the vicinity of both hem portions as shown in FIG. It is an integrally molded product of a type corresponding to a partition bar having expanded portions 20a and 20b. In both cases, the pressure-sensitive adhesive 3 is applied on the base portion 4 for use. The cross-sectional shape of the integrally molded partition member is not limited to these, and the cross-sectional shape of the partition rod portion may be, for example, another shape of the type shown in FIG. 3, FIG. 4, FIG. 7 to FIG. You may

As the material, the same material as described above for the partition rod 5 is used, and when the material itself has no releasability, at least both inclined surfaces 8 of the partition rod 5 are used.
As described above, the release agent is coated on the surface a, 8b and other surfaces that come into contact with the decorative material, if necessary. And as a material, especially polyolefin resins such as polyethylene and polypropylene are relatively inexpensive and have the required strength,
It is also the case that it is a preferable material because it also has water resistance, and the portion corresponding to the partition rod 5 may be a rod-shaped one in which the material is filled up to the inside, or may be hollow. In some cases, a foam may be used as in the case described above.

The pressure-sensitive adhesive to be applied is not particularly limited, and typical examples thereof include an acrylic pressure-sensitive adhesive and a rubber-based pressure-sensitive adhesive. Further, when the partition rod is coated with a release agent and used, the release agent used is not particularly limited as long as it can impart releasability to the formed cosmetic material. However, a few representative examples include silicone oils, stearates, and the like.

As the decorative material, usually, a decorative material in which an aggregate is dispersed in a synthetic resin matrix is preferably used. Among these raw materials for the decorative material, the synthetic resin raw material forming the synthetic resin matrix is , Synthetic resin emulsions or synthetic resin solutions are used, and various synthetic resin emulsions and solutions conventionally used for manufacturing decorative sheets for building surface finishes of this kind are used, including natural stone patterns. be able to. Synthetic resin emulsions are preferably used from the viewpoint that it is not necessary to consider the recovery of organic solvents and environmental problems. In particular, a synthetic resin emulsion that satisfies weather resistance, alkali resistance, water resistance, adhesiveness, flexibility, water absorption resistance, and the like is preferable. Specific examples thereof include, for example, an acrylic resin emulsion (an acrylic resin emulsion, an acrylic-styrene-based emulsion). 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 emulsion And the like. The resin matrix after drying of any of these resins has appropriate flexibility, and can be applied to a curved surface. Among them, acrylic resin emulsions are comparatively cheaper than other acrylic resin emulsions because they are particularly superior in terms of weather resistance. Therefore, when used as a sheet for finishing building surfaces such as interior / exterior wall surfaces or floor surfaces, It is preferable because it has long-term durability.

As the aggregate, various known aggregates used in the production of such type of decorative sheet containing aggregate can be used, and marble powder, granite powder, silica sand and other natural stones can be used. Powder, ceramic powder, or artificial coloring of these, such as so-called colored aggregates such as colored calcined silica sand and colored ceramic powder, natural stone fine particles, ceramic fine particles, or colored products thereof An inorganic material typified by an aggregate of at least one of the above is preferably used. Of course, an aggregate made of an organic material such as plastic may be used. However, an aggregate made of an inorganic material as described above is less durable and less discolored than an aggregate made of an organic material such as plastic. It is preferably used because of its good properties and low price.

It is preferable to use an aggregate mainly having a size of 6 to 300 mesh. It is to be noted that a desired color tone or wind can be obtained by appropriately combining one or two or more of artificially colored colored aggregates or particularly aggregates of the same color as the raw material that is not artificially colored. It is possible to manufacture various kinds of decorative materials by adjusting the combination.

If desired, mica, synthetic resin colored flakes, other scale-like solid additives, and other additives may be added separately to give a unique texture. For example, the scale-like additive is usually 200 mesh to
Those having a size of about 1 cm ² are preferably used.

The mixing ratio of the aggregate and the synthetic resin matrix varies depending on the kind and the texture of the decorative material, but the ratio of the synthetic resin emulsion or solution is the resin solid content and the aggregate is 100. 5 to 2 parts by weight
About 0 parts by weight is preferable, and about 10 to 20 parts by weight is particularly preferable.

By adopting a preferred embodiment in this range, the aggregate can be firmly held by the synthetic resin matrix,
Therefore, it is possible to obtain a decorative material which is not so brittle and has durability and strength while maintaining a heavy and deep texture. When the aggregate is too much, the flexibility of the obtained decorative material tends to decrease because the proportion of the synthetic resin that also functions as a binder decreases.
On the other hand, if the proportion of the aggregate is too small, the texture with depth and depth tends to deteriorate, and when the coating material containing the synthetic resin emulsion or solution and the aggregate is applied to the substrate and then dried and solidified. , Shrinkage and the like tend to occur, and cracks tend to occur.

A cosmetic material raw material composition (coating material) in which an aggregate is mixed with a synthetic resin emulsion or solution may further contain a filler, a film-forming aid, a thickener, a defoaming agent, and a pH adjuster, if necessary. You may add a chemical | medical agent etc., and you may add water etc. and an appropriate solvent etc. in order to make viscosity low.

The base material to which the cosmetic material composition is applied is, for example, the base material used in the manufacture of conventionally used decorative sheets for surface finishing of this kind. It can be used similarly. 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 water absorption or having low water absorption is used. A gauze cloth made of acrylic fiber or polyester fiber is particularly preferable. Non-absorbent or low-absorbent woven fabrics are preferred because those with high water absorption tend to expand due to moisture and tend to shrink during drying, and the dried product may warp and deform. It is preferable to use a woven fabric having no or low water absorption since such a problem does not occur.
In addition, many glass cloths, synthetic fiber non-woven fabrics, synthetic papers and the like which have little water absorption are preferably used. Further, in some cases, a plastic sheet, a rubber sheet, an aluminum sheet, a metal thin plate such as a zinc-coated steel sheet, or the like is also used.

The application of the cosmetic material composition onto the substrate is most commonly performed by a spraying method using a spraying gun or the like. In addition, you may apply using a trowel or other application device. The coating thickness is not particularly limited as it varies depending on the material and type used, but it is usually from 2 to 10
Approximately mm is divided into one or two or more times and is applied repeatedly.

After the applied cosmetic material composition is dried and solidified, the excess cosmetic material formed near the tip of the partition bar is scraped off with a sander or a cutter. A transparent coat layer (usually called a top coat) is provided on the surface of the decorative material for the purpose of imparting functions such as giving gloss to the surface of the decorative material, preventing stains on the surface after construction, and enhancing waterproofness as necessary. Have been formed). In the case of forming the top coat layer, as the resin used for the top coat, any of the transparent top coat resins usually used for this kind of decorative sheet for building surface finish can be used. 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. Therefore, it is possible to form a topcoat having relatively good durability on the surface of the decorative material. It is preferable because it is possible.

Typical acrylic resins for the top coat are acrylic-silicone resins and acrylic-urethane resins, which are used in the form of their emulsions or organic solvent solutions.

Of course, it is not essential that the top coat is applied to all kinds of decorative sheets for finishing the surface of buildings, and it is not used for finishing decorative sheets which do not want to have a surface gloss.

As the adhesive for adhering the obtained decorative sheet for surface finishing for the projected corners to the wall surface of a building, any of those usually used as these adhesives can be used, and there is no particular limitation. Although it is not a thing, synthetic rubber type, vinyl acetate resin type, polymer cement type, acrylic resin type,
Appropriate materials such as acrylic rubber, silicone rubber, and epoxy resin may be used.

On the both sides of the partition member 6 consisting of a taper portion forming partition bar 5 made of a polyethylene resin having a releasability at 90 degrees, and base materials 11a and 11b made of polyester woven fabric (brass cloth) respectively. The end portions of the base materials 11a and 11b are temporarily adhered onto the base portion 4 by placing them so that their end portions are substantially in contact with the hem ends 7a and 7b of the partition rod 5 (see FIG. 1 (b)). ), And then commercially available cosmetic raw material "Cera Granny" (manufactured by Yamamoto Ceramic Co., Ltd .: raw material for cosmetics in which aggregate is dispersed in acrylic resin emulsion) with a spray gun of 8 mm in diameter. After spraying (thickness: about 6 mm) and drying and solidifying to form the decorative material 12 (see FIG. 1C), the decorative material 12a formed near the tip of the partition bar 5 is scraped off with a sander (FIG. 1). See (d) Further Acrylic on it - about the thickness of Topputo layer made of silicone resin 0.03mm
A transparent topcoat layer was formed by coating and drying (the portion of the topcoat layer is not shown).

A set of 50 decorative sheets 13 for surface finishing of the projected corners (provided with partitioning member 6) thus obtained was stacked and packed into a set of 10 sheets, and placed on the bed of a truck for 20 km. After transporting, unloading, unpacking, and investigating damage, the edge parts 14a, 14
For b, no damage was observed on any of the sheets.

Next, as shown in FIG. 1 (e), the partition member 6 was manually removed, but the base materials 11a and 11b were temporarily fixed to the base portion 4 of the partition member 6 with the adhesive material 3. As it is only, it could be easily removed at the construction site. Then, an acrylic adhesive is applied to the exposed tapered surfaces 15a and 15b, and an epoxy modified acrylic resin adhesive is applied to the wall surface of the projected corner 2 at about 1000 g / m ^2.
After applying and making a comb with a comb spatula, as shown in FIG. 1 (f), the decorative sheets for surface finishing 13, 13 were adhered to both wall surfaces of the projecting corner 2 of the building 1, and the construction was performed. We were able to carry out construction in which the edge of the part (exposed line) appeared neatly.

Example 20 was carried out in the same manner as in Example 1 except that a partition member of the type having 20b was coated with the acrylic adhesive 3 on the base portion 4. However, the cross-sectional view of the construction state is shown in Figure 1.
It becomes as shown in 1.

When the partition member was removed during the construction, the partition rod and the base were never separated from each other, the removal operation was simple, and the working efficiency could be improved.
In addition, the adhesive was not squeezed out, and the construction was performed in which the edge of the projected corner appeared neatly.
