Description

  The present invention relates to a functional material, and more particularly to a functional material in which functionality is imparted to a surface portion of a substrate having an uneven shape.

Conventionally, as a base material used indoors and outdoors, many base materials which have an uneven | corrugated shape are used.
For example, natural wood having a grain such as a conduit or an annual ring, or a woody base material such as a decorative material in which a concavo-convex shape is formed by embossing or the like to express a grain pattern.
In addition, some water-circulating members such as bathroom floor pans and bathtubs molded from a resin material such as FRP have a concavo-convex shape formed to impart hydrophilicity and anti-slip properties (for example, the following patent documents) 1).
In addition, there are some water-carrying members such as kitchen sinks and counters that are molded of a metal material such as stainless steel, in which a concavo-convex shape is formed in order to impart scratch resistance (for example, see Patent Document 2 below).

By the way, functional materials to which antibacterial properties, antifungal properties, antifouling properties, and the like are imparted are often used as base materials used indoors and outdoors.
For such a functional material, a resin material or the like is molded by mixing a functional agent such as an antibacterial agent or an antifungal agent into the material itself. Thus, in the process of mixing the functional agent with the material itself, the functional agent is exposed only to a part of the surface portion, the performance of the functional agent mixed in the material is not exhibited, and the mixed functional agent is wasted. As a result, there was a problem that the cost was high.

Moreover, functional materials to which functionality is imparted by applying a paint containing a functional agent to form a coating layer as a surface treatment on various base materials and building materials are known.
For example, Patent Document 3 below proposes a cosmetic member in which a photocatalytic functional film is formed on the surface of a metal substrate having an uneven portion on the surface.
In this case, the photocatalytic semiconductor metal particles are filled in the concave portions by spraying or dipping and held in a thin layer on the convex portions, whereby the photocatalytic function is imparted to the surface of the metal substrate.
JP 2006-224347 A JP 2007-38626 A JP 2001-105525 A

However, in the cosmetic member described in Patent Document 3, a photocatalytic functional film is formed over the entire surface of the metal substrate, and the photocatalytic functional film is formed only at a location or part where functionality is desired. Was difficult.
In particular, the uneven shape as described above is often formed due to its texture, touch, anti-slip property, and scratch resistance. In such a case, the cosmetic member described in Patent Document 3 is applied. Then, since the photocatalytic functional film is formed in the concave and convex portions, the uneven shape is leveled by the formation of the photocatalytic functional film, and various performances (texture, touch, anti-slip, scratch resistance, etc.) There is also a problem of inhibiting the performance of).

  The present invention has been proposed in order to solve the above problems, and its purpose is to provide functionality at a low cost to the concave portion of the surface portion of the substrate having a concavo-convex shape and to exhibit the functionality for a long time. It is to provide a functional material that can be sustained.

  In order to achieve the above object, the functional material according to claim 1 specifies a concave portion of a base material having a concavo-convex shape on a surface portion, and jets a functional agent-containing solution into the concave portion by an ink jet coating injection device. Thus, a functional coating film is formed in the recess.

  In Claim 2, in Claim 1, the said recessed part images the surface of the said base material with an imaging means, and is specified by image processing.

  In Claim 3, in Claim 1 or 2, the said base material is a woody base material.

  According to a fourth aspect of the present invention, in the first or second aspect, the substrate is a watering member that has been embossed.

  In Claim 5, in any one of Claim 1 thru | or 4, the functional agent contained in the said functional agent containing solution is antiseptic | preservative, antibacterial agent, deodorant, insect repellent, water repellent, hydrophilic agent, At least one of the photocatalysts.

According to this invention of Claim 1 thru | or 5, a functional material specifies the recessed part of the base material which has an uneven | corrugated shape in the surface part, and injects a functional agent containing solution into this recessed part with an inkjet coating injection apparatus. Since the functional coating film is formed in the recess, the functional agent is mixed with the material itself, or compared with the conventional one in which the coating material containing the functional agent is applied to the entire surface of the substrate. And low cost. That is, since the functional agent-containing solution is sprayed only to the concave portion, the functional agent-containing solution is not wasted and the cost is reduced.
Furthermore, since it is set as the structure which injects a functional agent containing solution with an inkjet coating injection apparatus, control is easy and functionality can be provided to the desired site | part of a base material. That is, since the functional agent-containing solution can be sprayed only in the concave portion of the portion where functionality is desired, functionality can be imparted only to locations where functionality needs to be imparted, and low cost. It will be something.
In particular, since the functional agent-containing solution is jetted by the ink jet coating jetting device, the jetting amount of the functional agent-containing solution into the concave portion (filling amount into the concave portion) can be easily controlled. Therefore, by setting the amount so as not to block all the recesses, the various functions (texture, tactile sensation, anti-slip property, scratch resistance, etc.) of the uneven shape as described above are not hindered. Is a functional material to which is added.
Furthermore, since it is set as the structure which forms a functional coating film in the recessed part of the surface part of a base material, each performance which a various functional agent has can be maintained over a long term.

  According to the second aspect of the present invention, since the concave portion is specified based on the data imaged by the imaging means, the present invention can be applied to, for example, natural wood without molding data or mold data.

  In claim 3, since the base material is a wood-based base material, the conventional material that imparts functionality by coating the entire surface of the base material impairs the texture specific to wood. Since the functional material has a structure in which a functional coating film is formed in the concave portion of the surface portion of the wood-based base material, the functionality of the surface portion of the wood-based base material is reduced without losing all of the wood-specific texture. Can be granted. That is, the texture peculiar to wood remains on at least the convex part of the surface of the woody base material.

In Claim 4, since the said base material is made into the water surrounding member to which the embossing was given, by forming a functional coating film in a recessed part, it is antibacterial property in the recessed part of the water surrounding member which a stain | pollution | contamination tends to adhere. Water repellency can be imparted. Moreover, in order to improve drainage property, hydrophilicity can also be provided to a recessed part.
In particular, when the base material is a watering member, the surface portion is often cleaned with a cleaning tool such as a brush, but it is dried and solidified by forming a functional coating film in a minute recess. Thus, the functional agent held in the recess is difficult to peel off, and thus the functionality can be maintained for a long time.

In claim 5, the functional agent contained in the functional agent-containing solution is at least one of antiseptics, antibacterial agents, deodorants, insect repellents, water repellents, hydrophilic agents, and photocatalysts. By selectively containing a functional agent according to the construction site where the material is used, a functional material with high marketability is obtained.
In particular, as described above, the functional agent-containing solution is jetted by the inkjet coating jetting device to form a functional coating film in the recess, so that the spraying location of the functional agent-containing solution can be finely controlled. is there. For example, a functional agent-containing solution containing functional agents having different performances can be sprayed into the recesses, and a functional material having a plurality of functionalities can be provided depending on the construction location.

According to the above, a known one can be selected as appropriate, and any one such as a drop-on-demand piezo method, a drop-on-demand valve method, or a continuous charging deflection method can be applied.

The functional agent-containing solution 14a is a solution in which, for example, a resin, a solvent, a curing agent, an additive, or the like is mixed with a functional agent described later, and a known inkjet ink, for example, methyl ethyl ketone, ethanol, acetone, or the like is used as a solvent. Quick-drying inks, oil-based oil-based inks, UV curable inks that are cured by irradiating ultraviolet rays, water-based inks, and the like are applicable, but are configured so as not to impair the performance of the functional agents contained, and at least weather resistance and water resistance It is preferable to have it.
In addition, the functional agent-containing solution 14a is appropriately selected from the adjustment of viscosity and each of the above-described constituent materials according to the above-described inkjet nozzle driving method and the physical properties of the surface portion 11a of the water-circulating member 11, such as permeability. In particular, when a woody base material is applied as the base material, it is preferably fixed to the concave portion 13 when impregnated in the concave portion 13 without being impregnated, and acrylic, methacrylic, It is preferable that a urethane type resin or a fluorine type resin is contained.
As a mode for imparting quick drying property or fast curing property to the functional agent-containing solution 14a, a UV curable resin (for example, a radical polymerization type UV curable resin, a cationic polymerization type UV curable resin, or the like) is added. You may make it do.

  Examples of the functional agent contained in the functional agent-containing solution 14a include preservatives, antibacterial agents, deodorants, insect repellents, water repellents, hydrophilic agents, and photocatalysts.

Such a functional agent may be dissolved in the above-described solvent to become a liquid or particles dispersed in the solvent depending on the physical properties. Moreover, although the compounding quantity changes with functional agents, what is necessary is just to be 0.1 weight%-20 weight%.
In addition, when dispersing particles in a solvent, those having a particle diameter of several nm to several μm are preferable as the particles to be used, and it is preferable to appropriately mix a known dispersion medium so that precipitation or the like does not occur.
In addition, the mixing ratio of each constituent material of the functional agent-containing solution 14a can be selected as appropriate according to the physical properties of the water-circulating member 11, construction locations, resins, solvents, and functional agents.
Furthermore, when the functional agent-containing solution 14a is sprayed onto the water-circulating member 11 as in the present embodiment, it is preferable to use a transparent color, but it may have a colorant such as a pigment or dye added thereto. .

  The control unit 30 includes a CPU 31 that constitutes a control calculation means, a storage means 32 that stores a control program 32a, a memory 33 that stores captured image data 33a and recess data 33b obtained by imaging, and the like. Concave data generating means is configured.

Next, a process of manufacturing the functional material 10 using the functional material manufacturing apparatus A having the above-described configuration will be described.
First, the CCD line sensor unit 21 is driven to image the surface of the water-surrounding member 11 placed on the base 20.
At this time, as described above, the imaging unit 24 moves and scans the water circulating member 11 in the Y direction, and sequentially captures images line by line to capture the entire surface of the water circulating member 11. The captured image is converted to a digital image by the A / D converter 22b and stored in the memory 33 as captured image data 33a.

Next, the recessed portion 13 is specified by the image processing program from the stored captured image data 33a.
Here, as a method of specifying the recess 13 from the captured image data 33a, a known image processing technique can be applied. For example, the light from the light source 24b is photographed so as to be irradiated obliquely with respect to the surface of the water-circulating member 11, and a portion where a shadow (dark portion) is formed is specified as the concave portion 13. Good. That is, the brightness distribution may be detected and specified.
As such a method, the difference between the brightness value corresponding to the convex portion 12 in the captured image data 33a represented by the brightness value of 256 gradations for each pixel by the shading process is a certain value (threshold value) or more. The portion corresponding to the lost data may be specified as the recess 13. At this time, filter processing such as expansion and contraction may be performed so as not to detect minute noise. Such a method for detecting irregularities is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2-242108 and 3-295408.

When the water circulating member 11 is applied as a base material as in the present embodiment, since it is often monochromatic, it is possible to easily identify the concave portion 13 according to light and dark as described above.
Alternatively, when the image is picked up by a color sensor, the concave portion 13 may be specified by color shading processing based on RGB color data, or the concave portion 13 can be specified by applying a known image processing technique. .
In addition, for example, when embossing is performed based on pre-stored molding data or mold data, the storage unit 32 stores the data based on those data, as indicated by a two-dot chain line in FIG. The recess 13 may be specified based on the stored molding data 32b. In this case, imaging by the imaging means 21 is not necessary, and the inkjet coating injection unit 25 is driven and controlled as described later by positioning based on the size and position information of the recess 13 obtained from the molding data 32b. Thus, the functional coating film 14 can be easily formed in the recess 13.

The concave portion 13 specified as described above is stored in the memory 33 as concave portion data 33b including size and position information.
Next, based on the stored recess data 33b, the inkjet coating injection unit 25 is driven, and the nozzle head 29 is driven and controlled by the nozzle head driving means 26a to the specified recess 13, and the functional agent-containing solution 14a is supplied from each injection nozzle 29a. Is injected (see FIG. 2B).
At this time, in order to improve the quick drying property and the fast curing property of the functional agent-containing solution 14a injected from the injection nozzle 29a, the solid resin added to the functional agent-containing solution 14a is heated and melted immediately before the injection, It is good also as an aspect which forms the functional coating film 14 by thermally radiating and hardening | curing the functional agent containing solution 14a, when it injects with respect to the surrounding member 11, and it lands in the recessed part 13. FIG.
Further, an adhesive layer or a receiving layer for easily fixing the functional agent to the recess 13 may be formed before the functional agent-containing solution 14a is sprayed.
Further, when different functionalities are provided for each part of the water-circulating member 11, a plurality of functional agent-containing solutions 14a containing different functional agents are selectively injected from different injection nozzles 29a depending on the part. It may be.

As described above, the functional agent-containing solution 14a sprayed and filled in the concave portion 13 is dried and solidified, and the functional coating film 14 is formed in the concave portion 13 of the surface portion 11a of the water circulating member 11 as shown in FIG. It is formed. Thereby, the water-circulating member 11 becomes the functional material 10 to which functionality is imparted.
Note that the number of droplets of the functional agent-containing solution 14a ejected from the ejection nozzle 29a is preferably set as appropriate according to the size of the recess 13 and the size of the droplets. When the coating film 14 is formed, the amount is preferably set so as not to close the recess 13.
That is, in this embodiment, the number of droplets is controlled so that the filling amount of the functional coating film 14 filled in the recess 13 and dried and solidified becomes a depth D2 that is half or less of the depth D1 of the recess 13. Yes.
As a result, functionality is imparted without impairing the performance of the uneven shape (emboss) formed to give various performances to the water-circulating member 11 (texture, touch, anti-slip property, scratch resistance, etc.). can do.

Such a control of the number of droplets is easy on the basis of the data of the depth D1 because the depth D1 of the recess 13 is set in advance in the water turnaround member 11 of the present embodiment as described above. Can be done.
In particular, since the functional agent-containing solution 14a is jetted by the ink jet coating jet unit 25, the jet amount of the functional agent-containing solution 14a into the concave portion 13 (filling amount into the concave portion) can be easily controlled.
In addition, the depth of the functional coating film 14 formed in the recessed part 13 is not restricted to what was mentioned above, What is necessary is just to make it the quantity which does not inhibit the above performance which an uneven | corrugated shape has. That is, the depth D3 from the surface of the convex part 12 to the surface of the functional coating film 14 should just be made into the depth D3 which does not inhibit each said performance which an uneven | corrugated shape has. Or as a base material, you may make it block | close all the recessed parts 13 about the base material which has the uneven | corrugated shape in which the above performance is not calculated | required especially.

Moreover, when forming the functional coating film 14 as mentioned above, it is preferable to apply the functional agent containing solution 14a according to the construction location of the functional material 10. FIG. As in the present embodiment, when the water circulating member 11 is applied as a base material to which functionality is imparted, for example, the functional material is imparted to the water circulating member 11 such as a bathroom floor pan or a bathtub. In the case of 10, it is preferable that a hydrophilic agent is contained. According to this, the hydrophilic performance of the concavo-convex shape can be enhanced more effectively.
In addition, when the functional material 10 is provided by imparting functionality to the water circulation member 11 such as a kitchen sink or counter, it is preferable that an antibacterial agent or a water repellent is contained. According to this, antibacterial properties and antifouling properties can be imparted together with the scratch resistance of the uneven shape.
Further, when a plurality of functionalities are desired to be imparted to the surface portion 11a of the water turnaround member 11, the plurality of recesses 13 may be filled with a functional agent-containing solution 14a containing functional agents having different performances. .

Furthermore, it is good also as a structure which forms the functional coating film 14 only in the recessed part 13 of the site | part which wants to provide functionality, for example, only the skirt part near the outer peripheral edge part of a front door, the floor surface of a kitchen cabinet or a pillar, etc. It is good also as a structure which forms the functional coating film 14 in which the insect repellent was contained.
In particular, in this embodiment, since the functional agent-containing solution 14a is jetted by the inkjet coating jet unit 25, the control is easy, and functionality can be imparted to the concave portion 13 at a desired portion of the base material 11. . That is, since the functional agent-containing solution 14a can be filled in the concave portion 13 where the functionality is to be imparted, the functionality can be imparted only to the concave portion 13 in the vicinity of the location where the functionality needs to be imparted. And low cost.

As described above, in the present embodiment, the functional material 10 specifies the concave portion 13 of the water-circulating member 11 having the concave and convex shape on the surface portion 11a, and the functional agent-containing solution is formed in the concave portion 13 by the inkjet coating jet unit 25. Since the functional coating film 14 is formed in the recess 13 by spraying 14a, the functional agent is mixed with the material itself, or the coating material containing the functional agent is applied to the entire surface of the substrate. Compared to the product, the cost is low. That is, since the functional agent-containing solution 14a is sprayed only to the concave portion 13, the functional agent-containing solution 14a is not wasted and the cost is reduced.
Furthermore, since the functional agent-containing solution 14a is sprayed on the concave portion 13 of the surface portion 11a of the base material 11 to form the functional coating film 14 in the concave portion 13, each performance of various functional agents is provided. Can be maintained over a long period of time.
In particular, when the water turnaround member 11 is applied as a base material as in the present embodiment, the surface portion 11a is often cleaned with a cleaning tool such as a brush, but the functional coating film is formed on the minute recess 13. By forming 14, the functional coating film 14 is difficult to peel off, and thus the functionality can be maintained for a long time.

In addition, as the base material 11 applicable to this embodiment, what kind of thing may be sufficient as long as it has an uneven | corrugated shape in the surface part, and the magnitude | size of an uneven | corrugated shape is according to the kind of the base material 11 to which it applies. This embodiment can also be selected as appropriate and has been conventionally used as an interior building material and exterior building material for buildings, for example, other resin materials, metal materials, wood base materials, ceramic materials, etc. Is possible.

In addition, as other resin materials, at least the surface layer may be resin-based, and a decorative layer of a resin sheet is attached to a synthetic resin such as plastic or a laminated material, plywood, particle board, wood fiber board, etc. It can also be applied to those with a decorative coating made of resin.

Furthermore, as ceramic materials, it can be applied to bricks, tiles, ceramics, cement-based ceramic materials that contain cement as a main component and include reinforcing fibers and inorganic fillers, which are used for outer walls and roofs. .
Furthermore, as the wood base material, it is sufficient that at least the surface layer is wood base, and it can be applied to natural wood, laminated wood, plywood, particle board, wood fiber board and the like. Alternatively, these can be applied to a base material or a resin base material to which a decorative layer such as a wood veneer is attached.

When a woody base material is applied as the base material, the conventional texture that imparts functionality by painting the entire surface of the base material impairs the texture specific to wood, but according to this embodiment, wood Functionality can be imparted to the surface portion of the woody base material without impairing all of the unique texture. That is, a texture specific to wood remains on at least the convex portion of the surface of the wooden substrate.
When the conduit of the woody base material is specified as the recess 13 and the functional coating film 14 is formed, the functional agent-containing solution 14a is sprayed after the sealing, or also as the sealing agent, The functional coating film 14 may be formed.

Further, the shape is not limited to a plate shape as shown in the figure, and the present invention can be applied to various shapes of base materials such as a prismatic shape, a cylindrical shape, and a conical shape.
Furthermore, as construction sites where the functional material 10 is used, it can be used for interior and exterior, for example, in addition to the above, vanity, toilet room, door, floor, stairs, fence, pillar, handrail, shelf, It is suitable for kitchen panels, ceilings, cabinets and top plates for various furniture, inner walls, outer walls, roofs, and the like.
