Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for producing a decorative material for surface finishing at a protruding corner.
[0002]
[Prior art]
In recent years, sheet-shaped decorative materials have been widely used as decorative materials for finishing the interior or exterior of a building or other structure or floor surface.
[0003]
When a decorative sheet for surface finishing is affixed to the interior and exterior of a structure such as a building, the projecting corner of the building or the like is schematically illustrated as a finishing method as disclosed in, for example, JP-A-6-264593. 3 (a) to (d) (all are cross-sectional views), two surface finish decorative sheets 100a and 100b to be attached to two surfaces constituting the projecting corner 120 of the building 110 will be described. Each (both consisting of the base material sheet 101 and the decorative material layer 102) has a taper of, for example, a half angle (45 ° in this case) of the angle of the protruding corner portion 120 (90 ° in this case). The edge of the decorative sheet for surface finishing 100a, 100b is scraped off with, for example, a sander 105 so that the two edges are aligned with each other (see FIG. 3 (a)), and the end is several mm Finish The decorative sheet is displaced in the thickness direction and attached to the protruding corner 120 (see FIGS. 3B and 3C), and the protruding portion is scraped off by, for example, the sander 105 (see FIG. 3D). The technique is shown.
[0004]
[Problems to be solved by the invention]
However, since this method forms a sharp tapered edge required for finishing the protruding corner, the sheet is cut or sanded on site, so that the cutting angle becomes a predetermined angle. It requires relatively skill, including problems such as the need to cut while adjusting at the site, and it takes a lot of time and work efficiency is low. After forming the taper part by cutting or sanding in advance at the factory It can be transported to the work site and installed, but even if it is cut or sanded at the factory to form the tapered part, the tapered surface will match well if it is not polished to the tapered shape as designed. Since it looks unpleasant, it needs to be carefully polished as before, it takes a lot of time, and the production efficiency is unchanged, Regardless of the misalignment, the joint where the tapered part after construction is overlapped is relatively thin and only adhesive is applied, so the adhesive strength of this part is relatively weak, and thermal expansion and contraction due to repeated sunshine for many years There are problems such as repeated peeling or peeling off from the part when exposed to wind and rain for many years, and water etc. easily invades, and when adhesive sticks out during bonding, Since the aggregate contained in the decorative material layer is not included, the color tone cannot be adjusted to the same as that of the decorative material layer, and there is a problem that the appearance is slightly deteriorated.
[0005]
Apart from this, the present inventor further examined a method as shown in FIG. FIG. 4 is a schematic cross-sectional view of a process for explaining a method for manufacturing a decorative material for finishing a corner surface that has been studied by the present inventors. As shown in FIG. 4 (a), a decorative sheet for surface finishing (hereinafter sometimes referred to as a laminated sheet) composed of a base sheet 101 and a decorative material layer 102 is formed from an arrow 130 by an appropriate cutter such as a cutter knife. The material sheet 101 is left and cut into the decorative material layer 102 in a substantially straight line, and as shown in FIG. 4 (b), the base sheet 101 is bent from the portion where the cut is made, As shown in FIG. 4 (c), the base sheet 101 side is in contact with the pad 11 on the pad 11 having a surface bent at substantially the same angle α as the shape of the cross-section of the target protruding corner. The material 3 for the cosmetic material having the same composition and the same color as the decorative material layer 102 is sprayed from the spray gun 4, for example, and applied from above the open cut 107. It is difficult to concentrate and spray only on the part of the cut 107 having an open coating area because the cosmetic material 3 blown out together with the compressed air from the nozzle of the spray gun is radially spread and ejected. The cosmetic material 3 is applied to the surface 109 of the decorative material layer 102 so as not to be contaminated, and the surface 109 of the decorative material layer 102 is preliminarily referred to as a curing tape or a curing sheet. Then, a sealing sheet 108 to which an adhesive material or the like is applied is attached to the back side, and the surface 109 of the decorative material layer 102 is covered. In this way, the raw material 3 for the cosmetic material is sprayed from the spray gun 4 to form a portion 102b that protrudes from the joint portion 102a and is applied (see FIG. 4D). For example, the protruding portion 102b shown obliquely below the dotted line 90 is removed together with the sealing sheet 108, and the angle of this portion is not shown but the joint portion 102a is dry. The surface of the joint portion 102a is ground by a method such as sanding so that the desired angle α of the protruding corner portion is obtained.
[0006]
However, this method requires a sticker sheet 108 to be attached or peeled off within a specific time (that is, 102b is semi-dry), which is very laborious and costly. And the problem that the raw material 3 for the cosmetic material of the portion 102b that has been applied is wasted.
[0007]
4A is the same process up to (b) in FIG. 4, and thereafter, as shown in FIG. 5 in another process cross-sectional view, as shown in FIG. Applying the joint 102c almost flat so that it does not bulge or dry on the surface of the surface 109 of the decorative material layer 102 with a spatula or a trowel so that it does not spill or sag. A method of forming a protruding corner is often employed.
[0008]
However, this method also has a problem that the strength of this portion is weak because the protruding corner portion is chamfered as illustrated. Moreover, the decorative material layer 102 is not one-color-blown, but two-color-blown or three-color-blown (two or three different types of cosmetic materials adjusted to different colors are sprayed separately or two heads) When using a spatula or a trowel, it is difficult to finish the same pattern as multi-color simultaneous spraying as described above. There is also.
[0009]
The present invention solves the above-mentioned problems of the method of manufacturing the decorative material for surface finishing of the protruding corners, the production process can be omitted, the production is simple, the production efficiency is good, the waste of the raw material for the cosmetic material to be used is small, and the production The cost can be kept low, there is no problem as described with reference to FIGS. 3, 4 and 5, and the amount of the cosmetic material applied to the joint can be relatively large. High-strength, durable, easy-to-adjust the color tone of the cosmetic raw material applied to the joint to a harmonious one that does not feel uncomfortable, and easy to apply to the corners on the spot. An object of the present invention is to provide a method for producing a surface finish decorative material.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, in order to facilitate understanding of the present invention, specific embodiments of the present invention will be described with reference to the drawings. However, the present invention is limited to only those specifically described in the embodiments. It is not something.
[0020]
FIG. 1 and FIG. 2 are process perspective views showing a preferred embodiment of a method for producing a decorative material for surface finishing of a corner of the present invention, and a process perspective view showing a manufacturing-construction process also showing its construction process. . 1 (a), (b), (c) and (d), (e), (f), (g) in FIG. 2 are a series of steps from FIG. It is drawn separately in FIG. 1 and FIG.
[0021]
As shown in FIG. 1 (a), for example, a decorative material 3 as a raw material of the decorative material layer 2 is formed on a non-woven fabric, a woven fabric or other foldable base sheet 1, for example, 4 in FIG. 1 (a). The laminated sheet 5 on which the decorative material layer 2 is formed is prepared by spraying from a spray gun as shown in FIG.
[0022]
Next, as shown in FIG. 1 (b), a substantially straight cut 7 is made in the thickness direction of the decorative material layer 2 of the laminated sheet 5. In FIG.1 (b), 6 has shown the cutter knife. The means for making the cut 7 is not limited to the cutter knife, as long as the purpose is achieved.
[0023]
Next, as shown in FIG. 1 (c), the laminated sheet 5 is folded into two substantially along the cut line 7 of the decorative material layer 2 so that the base sheet 1 is inside. Here, the cut surface of the decorative material layer that appears by folding in almost two is the surface indicated by reference numeral 8, and the surface of the decorative material layer is the surface indicated by reference numeral 9.
[0024]
Next, as shown in FIG. 2 (d), the plurality of laminated sheets 5 folded in two are brought into contact with each other so that the surfaces 9 of the decorative material layer 2 face each other while being folded in two. Arrangement is made so that the cut surfaces 8 of the decorative material layer appearing by folding in approximately two are substantially in the same plane.
[0025]
Then, on the cut surface 8 of the decorative material layer 2 of the laminated sheet 5 that is folded in half, the raw material 3 for the decorative material having the same composition and the same color as that shown in FIG. It sprays and applies from a spray gun (application layer 10). In this case, since the surfaces 9 of the decorative material layer 2 are arranged in contact with each other so as to face each other, the cosmetic material 3 is sprayed only on the cut surface 8 and applied. The cosmetic material 3 is not applied to the surface 9 of 2 and the surface 9 of the decorative material layer 2 is not soiled. There is a risk that the cosmetic material 3 is applied to the outermost surface 9 of the decorative material layer 2 positioned on the left and right outer sides of the laminated sheet 5 that is folded in two and the surface 9 of the decorative material layer 2 is soiled. In some cases, only the surface 9 of the decorative material layer 2 on both sides may be sealed with the curing sheet or the curing tape described above, and if the number of the laminated sheets 5 folded in two is considerably increased, for example, If one building, or the number of batches to be used for a building, or several times that number is used at one time, only two seals are required on both sides, so that it can be produced very efficiently. Moreover, if the method of spraying is good, since the cosmetic material raw material sprayed from the nozzle of the spray gun is radiated as described above, the surface 9 of the cosmetic material layer 2 on both sides can be applied without soiling without sealing. . On the other hand, when the method as shown in FIG. 4 is adopted, the surface 109 of the decorative material layer 120 must be sealed one by one and two by left and right, which is extremely inefficient.
[0026]
Next, as shown in FIG. 2 (e), the base sheet 1 side is a padding mold on a padding mold 11 having a surface bent at an angle α substantially equal to or slightly smaller than the angle formed by the cross section of the protruding corner. 11 so that the cut sheet 8 is coated with the cosmetic material 3 (coating layer 10) so that each of the laminated sheets 5 has an angle so that the folding angle thereof coincides with the angle α of the pad 11. Is spread, and the applied cosmetic material 3 (coating layer 10) is dried. The rough finished product thus obtained is bent at a desired angle on the inner surface side where the base sheet is present, but the formed coating layer 10 is slightly thicker, so this rises. The portion is polished by an appropriate means such as a sander, and is squared to a desired angle as shown in FIG. Then, if necessary, from the surface side, a synthetic resin emulsion or solution that becomes transparent after drying is thinly applied to the surface, dried, and a top coat layer is applied. The topcoat layer may be applied as necessary and is not always necessary. In particular, when a matte decorative material layer is desired, the top coat layer may not be applied. In addition, by applying a topcoat layer, the decorative material is given a surface gloss, or after polishing, the resin layer is shaved and suppressed from appearing whitish due to irregular reflections, weather resistance, water resistance, antifouling properties, etc. It is effective to give further.
[0027]
And the decorative material for surface finishing of the protruding corner portion of the present invention thus obtained has a protruding corner portion 12 of the building or structure on the base sheet side by an appropriate adhesive as shown in FIG. Adhered and fixed to.
[0028]
The foldable base material sheet used in the method for producing the decorative material for surface finishing of the projected corner of the present invention may be any sheet material that can reinforce the strength of the decorative material layer and can be folded. The base sheet made of is particularly preferable because it is light and has good adhesiveness. Specifically, for example, a woven fabric or a non-woven fabric made of synthetic fiber or inorganic fiber, for example, a cold chill or a non-woven fabric made of acrylic fiber or polyester fiber, or glass. Fabrics such as fiber woven fabric, glass wool nonwoven fabric, and synthetic paper are preferable. Non-water-absorbing or low-water-absorbing fabrics are preferred because those with high water absorption tend to expand due to moisture and tend to shrink during drying, and the product after drying may be warped and deformed. However, it is preferable to use a cloth-like material having no water absorption or low water absorption because such a problem does not occur.
[0029]
In addition, examples of the base sheet include aluminum sheets, galvanized steel sheets and other metal sheets, metal wire nets, expanded metals, rubber sheets, and synthetic resin sheets.
[0030]
In the present invention, the decorative material layer is preferably one in which an aggregate is dispersed in a synthetic resin component, but is not particularly limited thereto, and the decorative material for the surface finish decorative material at the protruding corner is used. Any material layer can be used as long as it does not impair the object of the present invention.
[0031]
As a raw material for the cosmetic material for forming the decorative material layer, a synthetic resin emulsion or a mixture of a synthetic resin solution and an aggregate (sometimes abbreviated as a coating material or a spraying material) is preferably used. As raw materials for the components, various synthetic resin emulsions and solutions conventionally used in the production of decorative materials having a natural stone pattern can be used. Synthetic resin emulsions are preferably used from the viewpoint that there is no need to take into consideration the recovery of organic solvents and environmental problems. In particular, a synthetic resin emulsion satisfying weather resistance, alkali resistance, water resistance, adhesiveness, flexibility, water absorption resistance, and the like is preferable. Specific examples thereof include acrylic resin emulsions (acrylic-styrene resin emulsions, acrylic resins). -Urethane resin emulsion, acrylic-silicon resin emulsion, acrylic-fluorine resin emulsion are also included), vinyl acetate resin emulsion such as ethylene-vinyl acetate resin, vinyl chloride resin emulsion, urethane resin emulsion, etc. . In any of these resins, the resin component after drying also has appropriate flexibility and is easy to be applied to the protruding corner. Above all, acrylic resin emulsions are relatively inexpensive, but they are superior in terms of weather resistance, so they have long-term durability, such as when used as a decorative material for surface finishing at the corners of buildings and structures. preferable.
[0032]
As described above, when an aggregate is blended with a synthetic resin raw material, the aggregate to be blended includes various known bones conventionally used in the production of decorative materials having a natural stone-like pattern. It can be used as marble powder, granite powder, cinnabar and other natural stone powder, ceramic powder, plastic aggregate, or so-called colored aggregate such as colored calcined cinnabar or colored ceramic powder. Among them, the aggregate made of an inorganic material is preferably used from the viewpoint of cost.
[0033]
It is preferable to use an aggregate mainly having a particle size of 0.05 to 1.5 mm. Here, when the aggregate is not spherical, the particle size is the largest of the particles in the state where the particles of the observed aggregate can be seen when observing with an appropriate instrument such as a microscope at the time of measurement. The diameter is the particle size of the aggregate particle.
[0034]
It should be noted that a desired color tone or wind can be obtained by appropriately using one or two or more kinds of artificially colored colored aggregates, or in particular, aggregates of uncolored raw materials. Can be adjusted.
[0035]
The blending ratio of the aggregate and the synthetic resin component is slightly different depending on the purpose, such as the texture layer of the decorative material, but the ratio of the synthetic resin emulsion or the solution is 100 parts by weight of the aggregate in the solid content. The amount is preferably about 5 to 20 parts by weight.
[0036]
By adopting a preferred embodiment within this range, the synthetic resin component is an amount sufficient to serve as a binder for the aggregate, and there is not too much synthetic resin component to cause shrinkage or cracking, and Natural stone-like textures and the like can be easily produced, and can be used as a decorative material layer that is durable and has an appropriate strength.
[0037]
In order to adjust the color tone of the decorative material layer, one or two or more compounding amounts of various aggregates and so-called colored aggregates obtained by artificially coloring them, and the type, particle size, and color of the aggregate to be added are appropriately selected. This is achieved by selecting and blending, or adding a colorant as necessary.
[0038]
The cosmetic material thus prepared is not particularly limited, but a multicolor pattern using two or more types of cosmetic materials having different color tones and using individual single-head guns for each color tone. It is often used to form a multi-colored makeup layer by using a multi-headed gun such as a two-headed gun or a three-headed gun to form a multi-colored cosmetic layer. A textured material is preferred because it is easy to obtain.
[0039]
Moreover, in order to give a unique texture as needed, a colored flaky synthetic resin flake of one color or two or more colors may be added to the cosmetic material as necessary.
Various known flaky synthetic resin flakes can be used. Among them, it is preferable to use irregular and flexible colored flaky resin flakes (hereinafter sometimes referred to as colored flaky irregularly shaped flexible resin flakes). Although not particularly limited, the colored flaky amorphous flexible resin flakes obtained by the following production method newly developed and proposed by the present applicant can be said to be one of the preferable ones. That is, a mixture composed of an aggregate and a synthetic resin emulsion or solution and, if necessary, a coloring material, a flat material having a peelable or smooth surface, such as a polypropylene film, a foam sheet, a silicone rubber sheet, Blow thinly on a fluororesin film or sheet using a spray gun, etc. and dry. When thinly sprayed, the thickness is usually non-uniform without intentionally non-uniformly spraying. However, in some cases, non-sprayed portions may be non-uniformly thinly sprayed to such an extent that non-sprayed portions are partially generated. This is dried, and a substantially continuous but flexible thin resin sheet obtained by peeling from the flat material having peelability is obtained, and this sheet is mixed in the raw material for the cosmetic material and stirred. The colored flake-shaped amorphous flexible resin flakes, which are divided into small pieces and made into irregularly shaped flakes, have high production efficiency and are thin and flexible. Even if it is applied by spraying, even slightly larger flakes can be easily passed through the nozzle of the spraying gun and applied, so there is no problem such as jumping of the end. In particular, flakes that are used when a slightly larger speckled pattern is imparted to the decorative material layer are preferably used.
[0040]
The thickness of the flaky amorphous flexible resin flakes is preferably 1 mm or less in average thickness, particularly about 0.2 to 0.9 mm, and has a flexibility, and is a raw material for cosmetics (referred to as a spraying material or a coating material). Even if it is added to the base sheet with a spray gun or the like, it easily passes through the nozzle of the spray gun and is extremely flexible. It is preferable without any phenomenon such as jumping from the surface.
[0041]
As the material of the aggregate used for obtaining a substantially continuous flexible thin resin sheet for the flaky amorphous flexible resin flakes, the same as the aggregate material mixed in the cosmetic material Aggregate of any material can be used. However, the aggregate has a slightly smaller particle size, and specifically, a particle size of 0.5 mm or less, more preferably about 0.01 mm to 0.5 mm is preferably used. Moreover, as a synthetic resin emulsion or solution for forming this flexible thin resin sheet, the same synthetic resin emulsion or solution used as a component of the above-mentioned cosmetic material can be used. In this case, as a mixing ratio of the aggregate and the synthetic resin emulsion or solution, the ratio of the synthetic resin emulsion or solution is preferably about 20 to 100 parts by weight, particularly 30 to 70 parts by weight based on 100 parts by weight of the aggregate. About parts by weight are preferred.
[0042]
Further, mica flakes typified by mica or colored mica may be added to the cosmetic material in order to give a unique texture as required.
In addition, a cosmetic material composition (coating material) in which an aggregate is blended with a synthetic resin emulsion or solution further includes a filler, a film-forming aid, a thickener, an antifoaming agent, and a pH adjuster as necessary. In order to adjust the viscosity, water or an appropriate solvent may be added.
[0043]
Application of the cosmetic material composition on the base sheet is most often performed by a spraying method using a spray gun or the like. In addition, although it may be applied using a scissors or other applicator, since the method using a spray gun is excellent in workability, the spray method using a spray gun is usually preferred. The coating thickness is not particularly limited because it varies depending on the materials and varieties to be used. Usually, about 2 to 10 mm is applied in one or two times, and is applied and dried.
[0044]
The synthetic resin emulsion or solution used for forming the topcoat layer may be any one that can form a transparent coating layer when dried, and the synthetic resin emulsion or solution described in the above-mentioned cosmetic material raw material. Similar synthetic resin emulsions or solutions can be used. In particular, acrylic-silicone resin-based or acrylic-fluorine resin-based emulsions or solutions are preferable because they are particularly excellent in weather resistance, water resistance, and antifouling properties.
[0045]
As the contact mold, a contact mold having a surface bent at an angle substantially equal to or slightly smaller than the angle formed by the cross section of the protruding corner is used, and it is made of a sheet-like material having a certain degree of rigidity, which is bent at the angle. For example, a substantially L-shaped cross section or a triangular prism having the above angle is used.
[0046]
In the case of a sheet-like material, it is a paperboard (for example, it is very convenient to use a thick paperboard already formed into an L shape such as “Fiber Angle” manufactured by Saga Paperboard Co., Ltd., and the cost is low). Examples include plastic plate moldings, wood plates, metal plates, ceramic plate moldings, glass plates, gypsum plate moldings, etc. In the case of triangular prisms, plastic moldings, wood, metal moldings, ceramic moldings, etc. There is no particular limitation as long as it does not impair the object of the present invention, such as an article, a glass molding, a gypsum molding, and a cement molding. Of these, paperboard is one of the preferred ones in terms of being able to reduce costs.
[0047]
As shown in FIG. 2 (e), the pad 11 is a pad having a surface bent at an angle α that is approximately equal to or slightly smaller than the angle formed by the intended cross section of the protruding corner. Of course, if the angle α is substantially equal to the angle formed by the cross section of the protruding corner, it can be easily adhered to the protruding corner using an adhesive, but this angle α is slightly smaller than the angle formed by the cross section of the protruding corner. If it is an angle, it will be slightly widened and fitted into the corner of the corner, so when trying to return to the original angle, a slight pressure will be applied to the building surface at the corner of the corner, resulting in better adhesion It is preferable. Further, in some cases, it is normal to support the decorative material that has been adhered before the adhesive is solidified. However, it is preferable that such a support may be omitted. The angle slightly smaller than the angle formed by the cross section of the protruding corner is not particularly limited, but it is preferable to make it smaller within the range of about 7% or less than the angle formed by the cross section of the protruding corner.
[0048]
