JP 2007-231586 A

  By the way, on the surface of the base material in the decorative building board as described above, for example, a stone or a brick may be printed to express a material such as wood. However, when only one material is printed on the surface of the base material, it is difficult to have a varied appearance. Further, even if two or more materials are printed on the surface of the base material, it is difficult to express the difference in texture between the materials only by printing expression, and the difference in the materials is difficult to be clarified.

  This indication is made | formed in view of the said reason, and it aims at providing the makeup | decoration building material in which the 2 or more raw material was printed and the difference of a raw material was expressed clearly.

  A decorative building material according to an aspect of the present disclosure is a decorative building material on which printing is performed on a surface of a base material, and the surface has a plurality of print regions having different surface roughnesses, and each of the print regions Different materials are printed at the same time.

  In the decorative building material according to one aspect of the present disclosure, two or more materials are printed, and the difference between the materials is clearly expressed.

FIG. 1 is a perspective view of a decorative building material according to an embodiment. FIG. 2A is a cross-sectional view orthogonal to the longitudinal direction of the above-described decorative building material. FIG. 2B is an enlarged view of a portion A in FIG. 2A. FIG. 3 is a horizontal sectional view of the above-described decorative building material.

(1) Outline Hereinafter, the decorative building material 1 of the present embodiment will be described with reference to FIGS. The decorative building material 1 of the present embodiment is a decorative building material on which printing is performed on the surface 20 of the base material 2.

  The surface 20 of the present embodiment has a plurality of print areas having different surface roughness. A different material is printed for each printing area. For this reason, the makeup | decoration building material 1 of this embodiment has the appearance which was rich in change which was formed with the 2 or more raw material, and the difference of a raw material is expressed clearly.

(2) Configuration Hereinafter, the configuration of the decorative building material 1 of the present embodiment will be described in detail. The decorative building material 1 according to the present embodiment shown in FIG. 1 is an outer wall material for horizontal stretching, and is constructed so that the surface 20 of the base material 2 faces the outdoor side.

  The decorative building material 1 is applied in a state where the back surface 21 (surface opposite to the front surface 20) of the base material 2 is along the wall base. In addition, in this indication, each composition of makeup building material 1 is explained using a direction in the state where it was constructed. Specifically, the direction from the substrate 2 toward the side opposite to the wall substrate is defined as the front, and the direction from the substrate 2 toward the wall substrate is defined as the rear.

  The main body of the decorative building material 1 is composed of a base material 2. The base material 2 is formed by, for example, extrusion molding, and the whole is formed from the same material. The base material 2 of the present embodiment is a ceramic siding material, for example, and is made of a hardened cement material.

  The base material 2 is formed in a rectangular plate shape that is long in the horizontal direction. The shape of the cross section orthogonal to the horizontal direction of the base material 2 is substantially uniform over the longitudinal direction of the base material 2.

  As shown in FIG. 2A, an upper solid portion 22 is formed at the upper end portion of the base material 2, and a lower solid portion 23 is formed at the lower end portion of the base material 2. In the state in which the decorative building material 1 is constructed, the upper solid portion 22 is opposed to the lower solid portion 23 of the other decorative building material 1 adjacent to the upper side, and the lower solid portion 23 is adjacent to the lower side of the other decorative building material 1 that is adjacent to the lower side. Opposite the upper solid portion 22.

  As shown in FIGS. 1 and 2A, a plurality of horizontal joints 3 are formed on the surface 20 of the base material 2 so as to be arranged at intervals in the vertical direction.

  Each horizontal joint 3 is a groove extending linearly in the longitudinal direction of the substrate 2. Each horizontal joint 3 is formed over the entire length of the base material 2 in the longitudinal direction.

  A plurality of protrusions 4 arranged in the upward direction are formed on the surface 20 of the substrate 2. Each protrusion 4 is constituted by a portion between adjacent horizontal joints 3 on the surface 20 of the base material 2.

  Each protrusion 4 is formed in a rectangular shape extending in the horizontal direction when viewed from the front. The front surface of each protrusion 4 is a substantially vertical surface.

  On the front surface of each protrusion 4, for example, a three-dimensional pattern representing the surface of the piece material is formed so that the protrusion 4 looks like a piece material corresponding to the motif of the decorative building material 1. Examples of the motif of the decorative building material 1 include an earthen wall pattern, a concrete wall pattern, a masonry pattern, a brickwork pattern, or a board pattern. For example, when the motif of the decorative building material 1 is an earthen wall pattern, a three-dimensional pattern representing the surface of the earth is formed on the front surface of each protrusion 4.

  Each horizontal joint 3 of the present embodiment is a box joint having a bottom surface 32, and has an upper surface 30, a lower surface 31, a bottom surface 32, and a plurality of ridges 33 as shown in FIG. 2B.

  The upper surface 30 constitutes the lower surface of the protrusion 4 above it, and the lower surface 31 constitutes the upper surface of the protrusion 4 below it. The plurality of ridges 33 are formed in a portion between the upper surface 30 and the lower surface 31 in each horizontal joint 3. The bottom surface 32 connects the top surface 30 and the surfaces of the plurality of ridges 33.

  The upper surface 30 extends rearward and obliquely downward from the lower edge of the front surface of the protrusion 4 thereon. That is, the upper surface 30 is inclined so that the portion closer to the back surface 21 of the base material 2 is positioned downward. For this reason, the upper surface 30 is not easily hit by light from obliquely upward, such as sunlight or illumination light, and a shadow is easily formed. In the upper surface 30 of the present embodiment, the inclination angle θ1 with respect to the vertical surface is 45 ° or more.

  The lower surface 31 is located below the upper surface 30. The lower surface 31 extends rearward and obliquely upward from the upper edge of the front surface of the protrusion 4 below. That is, the lower surface 31 is inclined so that the portion closer to the back surface 21 of the base material 2 is positioned upward. For this reason, when light, such as sunlight or illumination light, hits the makeup | decoration building material 1 from the front diagonally upper direction, the lower surface 31 is easy to be illuminated brightly.

  The lower surface 31 has a gentler slope than the upper surface 30. That is, the inclination angle θ2 of the lower surface 31 with respect to the vertical surface is smaller than the inclination angle θ1 of the upper surface 30 with respect to the vertical surface. In the present embodiment, when the decorative building material 1 is exposed to light such as sunlight or illumination light, the inclination angle θ2 is set to be less than 45 ° so that the lower surface 31 is illuminated brighter than the front surface of the protrusion 4. Yes.

  The bottom surface 32 extends downward from the rear edge (lower end) of the top surface 30. The bottom surface 32 of the present embodiment is a substantially vertical surface parallel to the front surface of the protrusion 4. When light such as sunlight or illuminating light hits the decorative building material 1 from obliquely upward from the front, a shadow of the protrusion 4 positioned above is easily formed on the bottom surface 32.

  Between the bottom surface 32 and the bottom surface 31, a plurality of ridges 33 arranged in the up-down direction are formed. The rear edge (upper end) of the lower surface 31 and the lower edge of the bottom surface 32 are connected to the surfaces of the plurality of ridges 33. That is, in the present embodiment, the bottom surface 32 and the bottom surface 31 are connected via the surfaces of the plurality of ridges 33.

  Each ridge 33 extends linearly in the longitudinal direction of the horizontal joint 3, and extends over the entire longitudinal direction of the lateral joint 3.

  In each horizontal joint 3, the plurality of ridges 33 protrude forward from the bottom surface 32. For this reason, the plurality of ridges 33 are easily illuminated brightly by the light as compared with the bottom surface 32. On the other hand, a shadow is formed in the portion 34 above the ridge 33 in the horizontal joint 3. In this case, the person who looks at the makeup building material 1 is given an impression that the portion 34 where the shadow is formed is located in the back of the horizontal joint 3 with respect to the ridge 33 rather than the actual position. For this reason, the makeup | decoration building material 1 becomes the external appearance in which the deep horizontal joint 3 was formed.

  The plurality of ridges 33 are located behind the front surface of the protrusion 4. Further, the lower ridge 33 is positioned forward, and all the ridges 33 are positioned behind the entire surface of the protrusion 4 as described above.

  Printing is applied to the entire surface 20 of the substrate 2 of the present embodiment. Specifically, the surface 20 of the substrate 2 has a plurality of print areas having different surface roughnesses, and each print area is subjected to different printing.

  The surface 20 of the present embodiment has a plurality of first print areas PA1, a plurality of second print areas PA2, and a plurality of third print areas PA3 as a plurality of print areas.

  Each first printing area PA1 is composed of a front surface of the protrusion 4 and a lower surface 31 of the horizontal joint 3 continuous thereto. Each first print area PA1 is printed to express one material selected from various materials such as soil, concrete, stone, brick, wood, and glass.

  The material printed in the first print area PA1 is the same material as the material expressed by the shape of the protrusion 4. For example, when the protrusion 4 has a shape representing a part of the earth wall, the first printing area PA1 is printed with a color and a pattern representing the surface of the earth.

  Each first print area PA1 has a surface roughness corresponding to the material printed in the first print area PA1. For the surface roughness in the present disclosure, for example, arithmetic average roughness Ra defined by JISB 0601: 2013 is used.

  Each second print area PA <b> 2 is configured by the surfaces of the plurality of ridges 33. Each second printing area PA2 is printed, for example, representing one material selected from the various materials.

  However, the material printed in the second print area PA2 is different from the material printed in the first print area PA1. For example, when the above-described soil material is printed in the first print area PA1, the second print area PA2 is printed with a color and a pattern representing the surface of the glass.

  Each second print area PA2 has a surface roughness corresponding to the material printed in the second print area PA2. In the present embodiment, the second printing area PA2 is formed so that the surface roughness is smaller than that of the first printing area PA1. For this reason, the difference in texture between the first printing area PA1 and the second printing area PA2 is clearly expressed.

  Each third print area PA <b> 3 includes an upper surface 30 and a bottom surface 32 of the horizontal joint 3. For example, each third print area PA3 is printed with the same material as the first print area PA1 and in a darker color than the first print area PA1. That is, the upper surface 30 and the bottom surface 32 are darker than the front surface and the lower surface 31 of the protrusion 4. For this reason, the third print area PA3 looks darker due to the influence of the shadow formed in the third print area PA3.

  The surface roughness of the third printing area PA3 is smaller than the surface roughness of the first printing area PA1. For this reason, the third printing area PA3 is likely to be seen as being located on the back surface 21 side of the substrate 2 from the actual position.

  Further, the surface roughness of the third printing area PA3 is larger than the surface roughness of the second printing area PA2. For this reason, the difference in texture between the third printing area PA3 and the second printing area PA2 is clearly expressed.

  The decorative building material 1 of this embodiment is provided with the coating film 5 formed over the whole surface 20 of the base material 2, as shown in FIG. The coating film 5 has a printing layer 52 formed by the printing described above.

  The coating film 5 of the present embodiment has, for example, an ink receiving layer 51, a printing layer 52, and a clear layer 53 in this order from the substrate 2 side.

  An ink receiving layer (ink receiving layer) 51 formed on the surface 20 of the substrate 2 makes it easy to fix the print layer 52 to the surface 20 of the substrate 2. The ink receiving layer 51 is formed by a technique such as spray coating, curtain coating, or roll coating. As a paint for forming the ink receiving layer 51, for example, a water-based paint is used. This paint is, for example, an acrylic resin paint or an acrylic silicon resin paint.

  The printing layer (ink layer) 52 formed on the surface (front surface) of the ink receiving layer 51 is formed by inkjet printing (inkjet coating). That is, the print layer 52 is an aggregate of a large number of ink dots (ink knobs) bonded to the ink receiving layer 51.

  The ink jet printing is performed using, for example, an ink jet printer that ejects a plurality of colors of ink. For example, water-based ink is used as the ink for forming the print layer 52.

  The print layer 52 in the present embodiment has a different dot density for each print region, and the dot density in each print region is higher in a print region with a smaller surface roughness. The difference in the dot density can be added by, for example, making one or both of the ink dot pitch and the ink dot diameter different for each print region.

  The dot density in the second print area PA2 shown in FIG. 2B is larger than the dot density in the first print area PA1. For this reason, the second print area PA2 is likely to appear smoother than the first print area PA1. Therefore, coupled with the influence of the difference in surface roughness between the first print area PA1 and the second print area PA2, the difference in texture between the first print area PA1 and the second print area PA2 is expressed more clearly.

  Further, the dot density of the third print area PA3 is larger than the dot density of the first print area PA1. For this reason, the third printing area PA3 looks darker than the first printing area PA1.

  Further, the dot density of the third print area PA3 is smaller than the dot density of the second print area PA1. For this reason, the second print area PA2 tends to appear smoother than the third print area PA3.

  As shown in FIG. 3, a clear layer 53 is formed on the surface (front surface) of the print layer 52. The clear layer 53 is a layer that transmits visible light, protects the print layer 52, and imparts clearness to enhance design.

  The clear layer 53 is formed by spray coating or the like, for example. As the clear paint for forming the clear layer 53, for example, an aqueous clear paint is used. The water-based clear paint is, for example, a paint such as acrylic, acrylic silicon, or acrylic urethane.

  The clear paint in the clear layer 53 is easily applied to the surface of the ink dots in the print layer 52, and is difficult to apply in the ink receiving layer 51 where the ink dots in the print layer 52 are not applied. For this reason, the clear layer 53 has a higher density of the clear paint as the dot density of the print layer 52 printed in the corresponding print region is higher. That is, in this case, the density of the clear paint in the second print area PA2 is larger than the density of the clear paint in the first print area PA1. For this reason, the second print area PA2 is likely to appear smoother than the first print area PA1.

(4) Supplement The design of the decorative building material 1 of the embodiment can be changed as appropriate.

  For example, the surface 20 of the substrate 2 may be printed with three or more different materials.

  Further, the dot density of each print region may be the same. In the above-described embodiment, the dot density of each printing area is decreased as the printing area has a larger surface roughness, but may be increased as the printing area has a larger surface roughness.

  Further, the range of each print area is not limited to the range of the embodiment. For example, the surface roughness of the front surface of the protrusion 4 and the surface roughness of the entire horizontal joint 3 may be made different, and different materials may be printed on them.

  Further, the front surface of the protrusion 4 may have a plurality of print areas, the surface roughness may be different for each print area, and different materials may be printed for each print area.

  In the horizontal joint 3 of the above embodiment, only one ridge 33 may be formed, or three or more ridges may be formed. Further, the ridge 33 can be omitted.

  Further, only one horizontal joint 3 may be formed on the base material 2. Further, the horizontal joint 3 may be formed only on a part of the base material 2 in the longitudinal direction.

  In addition, the coating film 5 is not limited to those directly formed on the surface 20 of the substrate 2, and may be formed via an underlayer such as a sealer, a primer, or an enamel paint. Further, the coating film 5 may not have at least one of the ink receiving layer 51 and the clear layer 53. Further, other layers such as an inorganic coating layer or a photocatalytic coating layer may be further formed on the surface of the coating film 5 as necessary.

  Moreover, the coating material of the ink receiving layer 51 is not limited, For example, you may form from an ultraviolet curable resin coating material. Moreover, the ink which forms the printing layer 52 is not limited, For example, an oil-based ink or an ultraviolet curable ink etc. may be sufficient. Moreover, the clear coating material which forms the clear layer 53 is not limited, For example, a solvent clear coating material, an ultraviolet curing clear coating material, etc. may be sufficient.

  Moreover, the base material 2 may be formed by methods other than extrusion molding, such as papermaking molding, cast molding, or press molding.

  The base material 2 is not limited to a ceramic base material, and may be a wood base material, a plastic base material, a metal base material, or the like. Further, the decorative building material 1 may be an outer wall material for vertical stretching in which the longitudinal direction of the base material 2 is parallel to the vertical direction. The technology of the present disclosure can also be applied to other exterior materials such as roofing materials, or interior materials such as inner wall materials and ceiling materials.

(5) Summary The decorative building material 1 according to the embodiment described above is a decorative building material that is printed on the surface 20 of the base material 2 and has the following configuration. The surface 20 has a plurality of print areas PA1, PA2 having different surface roughness. Different materials are printed for each of the print areas PA1 and PA2. Hereinafter, the makeup building material 1 having this configuration is referred to as a makeup building material 1 of a first aspect.

  Since the decorative building material 1 of the first aspect has a plurality of print areas PA1 and PA2 on which different materials are printed for each print area, the appearance is as if different materials are embedded in part. Further, since the plurality of print areas PA1 and PA2 have different surface roughness, the texture can be different for each of the print areas PA1 and PA2 on which printing is performed using different materials. For this reason, it can be set as the makeup | decoration building material 1 excellent in the design property by which the difference of the raw material was expressed clearly.

  Moreover, the makeup | decoration building material 1 of the said embodiment has the structure shown below in the makeup | decoration building material 1 of a 1st aspect. The printing is inkjet printing. The dot density is larger as the printing area has a smaller surface roughness. Hereinafter, this makeup building material 1 is referred to as the makeup building material 1 of the second aspect.

  The decorative building material 1 according to the second aspect is subjected to printing in which the dot density of the ink jet printing is larger and the printing area is more easily visible as the printing area has a smaller surface roughness. For this reason, each printing area PA1, PA2 can be made to have an appearance having a texture according to the printed material, and the difference in the material is expressed more clearly.

  Moreover, the makeup | decoration building material 1 of the said embodiment has the structure shown below in the makeup | decoration building material 1 of a 2nd aspect. A clear layer 53 is formed on the surface of the print layer 52 formed by the printing.
