Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In the drawings, the same reference sign indicates the same or equivalent. Embodiment 1.

FIG. 1 is a cross-sectional view of a main part showing the configuration of a decorative member (for example, a decorative panel for an elevator) manufactured by the decorative member manufacturing method according to Embodiment 1 of the present invention.

In the figure, reference numeral 11 denotes a base material that is bent and molded into a desired panel shape. The base material 11 is formed of, for example, metals such as copper, iron, titanium, aluminum alloy, and stainless steel, and inorganic materials such as glass, alone or in combination.

As shown in the figure, the surface of the base material 11 is roughened by forming minute irregularities by plastic deformation. For example, by sand shot processing, hairline force, non-directional sanding force, vertical and horizontal sanding, or a combination of these

The surface of the substrate 11 is roughened.

As a result, a coating film is formed on the surface of the base material 11 as in the prior art (that is, the decorative member disclosed in Japanese Patent Application Laid-Open No. 2001-130196 or a manufacturing method thereof), and the surface of the coating film is roughened. There is no need. That is, it is not necessary to form a coating film.

[0017] 13 is a resin sheet made of a transparent thermoplastic resin, and on one surface of this resin sheet 13, a colored pattern 16 is formed by a colorant by a method described later.

Reference numeral 18 denotes a pattern sheet, and the pattern sheet 18 includes a resin sheet 13 made of a transparent thermoplastic resin and a colored pattern 16 formed on the surface of the resin sheet 13. FIG. 2 is a cross-sectional view of the main part showing the configuration of the pattern sheet 18.

FIG. 3 is a diagram for explaining a method of manufacturing the pattern sheet 18.

In FIG. 3, reference numeral 20 denotes a roll in which a resin sheet 13 made of a transparent thermoplastic resin is previously scraped into a cylindrical shape.

Reference numeral 21 denotes a microcomputer, and 22 denotes an ink jet printer connected to the microcomputer 21.

In order to form the colored pattern 16 on the surface of the resin sheet 13, first, the resin sheet 13 is pulled out from the roll 20 and attached to the inkjet printer 22. The ink jet printer 22 is controlled by the microcomputer 21 and feeds the colorant so that the predetermined colored pattern 16 is formed on the surface of the resin sheet 13 while feeding the resin sheet 13 in the direction of the arrow. Spray on the surface of the grease sheet 13.

In this manner, a pattern sheet 18 in which a predetermined colored pattern 16 is formed on the surface of the resin sheet 13 is manufactured.

The reason why a colored pattern can be formed by directly spraying a colorant on the surface of a resin sheet (for example, an acrylic resin sheet) is due to recent advances in printing technology using the ink jet method.

Due to this advancement in printing technology, it is no longer necessary to form an ink receiving layer as in the prior art (that is, a decorative member or a manufacturing method thereof disclosed in Japanese Patent Laid-Open No. 2001-130196) when a pattern sheet is manufactured.

This makes it possible to produce a pattern sheet 18 in which the colored pattern 16 is directly formed on the surface of the resin sheet 13, and it is not necessary to form an ink receiving layer and print the colored pattern on the ink receiving layer as in the conventional case. .

FIG. 4 is a diagram for explaining a state when the pattern sheet 18 is overlaid on the roughened surface of the substrate 11.

As shown in FIG. 4, the pattern sheet 18 is overlaid so that the colored pattern 16 is in direct contact with the roughened surface of the substrate 11.

In addition, what the pattern sheet | seat 18 was piled up on the surface of the base material 11 shall be called the panel body mentioned later.

Next, the step of vacuum-bonding the pattern sheet 18 to the substrate 11 will be specifically described.

First, FIG. 5 is a perspective view showing an evacuation table used for manufacturing the decorative member shown in FIG.

In the figure, a flat vacuum evacuation table 31 includes a flat portion 31a on which the base material 11 is placed, a plurality of recesses 31b provided on the flat surface portion 31a, and a plurality of evacuations for exhausting the inside of the recesses 31b. And an exhaust passage 31c.

A packing 32 for keeping the air tightness of the flat surface portion 31a is provided continuously around the entire circumference at the peripheral portion of the flat surface portion 31a. FIG. 6 is an exploded perspective view showing a main part of the decorative member manufacturing apparatus (ie, vacuum pressing apparatus) having the vacuum evacuation table 31 shown in FIG.

In the figure, reference numeral 31 denotes a vacuum exhaust stand, and a plurality of exhaust pipes 33 for connecting an exhaust passage 31c to an exhaust pump (not shown) are connected to the side surface of the vacuum exhaust stand 31. On the flat surface portion 31a of 31, a panel body 34 formed by stacking the pattern sheet 18 on the base material 11 is placed.

FIG. 7 is a cross-sectional view showing the structure of the panel body 34. As shown in FIG. 7, the panel body 34 has the pattern sheet 18 on the surface of the substrate 11 roughened to a predetermined surface roughness. Superimposed

[0023] On the panel body 34, a sheet-like elastic body 35 having air permeability is covered.

Examples of the material of the elastic body 35 include silicone rubber caponji, Teflon (registered trademark) sponge, polyamide sponge, silicon fiber sheet, Teflon (registered trademark) fiber sheet, polyamide fiber sheet, glass fiber sheet, and glass fiber cotton. Stainless steel wool, titanium wool, or aluminum wool, such as resin, glass, metal, etc., having heat resistance and flexibility are used.

[0024] On the elastic body 35, a sheet-like cover 36 that covers the packing 32 over the entire circumference and keeps airtight between the flat surface portion 31a is covered.

As the cover 36, for example, a rubber sheet, a polyethylene sheet, or a silicon sheet is used. The peripheral edge of the cover 36 is sandwiched between the holding frame 37 and the packing 32.

As the material of the presser frame 37, for example, a material having sufficient rigidity and heat resistance such as metal, FRP, polyamide resin, or cement is used.

FIG. 8 is a perspective view showing a state when the vacuum pressure bonding apparatus shown in FIG. 6 is assembled.

A plurality of pressers 38 for pressing the presser frame 37 against the packing 32 are attached to the side of the assembly of the vacuum exhaust table 31 and the presser frame 37.

Each presser bar 38 is provided with a pressure adjusting mechanism 39 such as a spring.

For example, as shown in FIG. 9, one side of the holding frame 37 and one side of the vacuum exhaust table 31 are connected to each other. As a result, the press frame 37 can be easily aligned with the vacuum evacuation table 31, and the workability can be improved.

Next, FIG. 10 is a cross-sectional view showing an assembled state of the vacuum pressure bonding apparatus shown in FIG. 6. In this state, evacuation has not yet started.

This state force exhaust pump is driven, and the inside of the recess 31b is evacuated through the exhaust passage 31c.

As a result, the air between the cover 36 and the vacuum evacuation table 31 is discharged, and as shown in FIG. The elastic body 35 is compressed.

[0027] Thereafter, the vacuum pressure bonding apparatus is placed in a drying furnace (not shown) while being evacuated, and the panel body 34 is heated together with the vacuum pressure bonding apparatus.

Such heating increases the flexibility of the cover 36, and the cover 36 is pressed against the panel body 34 at atmospheric pressure to a finer portion.

Thus, the pattern sheet 18 on which the colored pattern 16 is formed on the surface of the resin sheet 13 allows the colored pattern 16 to be in direct contact with the roughened surface of the substrate 11 via the elastic body 35. The entire surface of the roughened surface of the base material 11 is uniformly pressed and welded over the entire surface.

[0028] Accordingly, the conventional coating layer or adhesive layer (that is, the decorative member disclosed in Japanese Patent Laid-Open No. 2001-130196 or a method for manufacturing the decorative member) is unnecessary.

In addition, since the surface of the base material 11 is roughened with minute unevenness, the surface of the base material 11 side of the resin sheet 13 softened by heating is the surface of the base material 11. The resin sheet 13 and the base material 11 are firmly welded by entering the recess.

[0029] As described above, the decorative member according to the present embodiment includes the resin sheet 13 made of transparent thermoplastic resin and the colored pattern 16 formed on the surface of the resin sheet 13. Pattern sheet 18 and base material 11 made of an inorganic material having a roughened surface, and pattern sheet 18 is arranged so that colored pattern 16 is in direct contact with the roughened surface of base material 11. Arranged and welded to substrate 11! RU

In addition, the method for producing a decorative member according to the present embodiment includes a pattern sheet 18 in which a colored pattern 16 is formed by printing a colorant on the surface of a resin sheet 13 made of a transparent thermoplastic resin. The pattern sheet manufacturing process to be manufactured, the substrate surface roughening process to roughen the surface of the base material 11 made of an inorganic material, and the colored pattern 16 of the pattern sheet 18 are roughened to the base material 11 A pattern sheet placement step of placing the pattern sheet 18 on the base material 11 so as to be in contact with the surface, and a panel body 34 constituted by placing the pattern sheet 18 on the surface of the base material 11 in a vacuum A heating step in which the substrate 11 and the pattern sheet 18 are welded by heating in a pressure-bonded state.

Therefore, according to the decorative member or the manufacturing method thereof according to the present embodiment, the pattern sheet 18 can be applied to the entire surface of the base material 11 without using an adhesive (that is, without forming an adhesive layer). It can be welded (fixed) uniformly and firmly.

That is, the pattern sheet 18 on which the colored pattern is formed can be directly and firmly welded (fixed) to the surface of the base material 11 uniformly and firmly.

Further, since the colored pattern 16 is sandwiched between the surface of the base sheet 11 and the resin sheet 13 which is a transparent thermoplastic resin, the resin sheet 13 functions as a protective film for the colored pattern 16. Therefore, the colored pattern 16 can be maintained for a long period of time as a decorative member without being peeled off or scratched by scratching or cleaning work that is not easily affected by external forces.

Furthermore, the structure is very simple compared to the conventional one (that is, the decorative member disclosed in Japanese Patent Laid-Open No. 2001-130196 or a method for manufacturing the decorative member), and vacuum crimping that requires no adhesive application process is performed only once. Therefore, the manufacturing process is simplified and the manufacturing time can be greatly reduced.

[0031] Embodiment 2.

The decorative member according to the present embodiment is characterized in that, in the decorative member according to the first embodiment, a coating layer containing organosilane is further formed on the roughened surface of the base material.

Further, the decorative member manufacturing method according to the present embodiment is the same as the decorative member manufacturing method according to the first embodiment, in which the coating layer containing organosilane on the roughened surface of the substrate is provided before the pattern sheet arranging step. And a coating layer forming step for forming the film. Since the decorative member or the manufacturing method thereof according to the present embodiment is the same as that of the first embodiment except that the coating layer is formed, the method for forming the coating layer will be mainly described.

That is, since it is the same as the first embodiment except that a coating layer is formed,

In the present embodiment, the method for forming the coating layer will be described in detail.

[0032] FIG. 12 is a cross-sectional view of a principal part showing the configuration of a decorative member (for example, an decorative panel for an elevator) manufactured by the decorative member manufacturing method according to the second embodiment.

In the figure, reference numeral 12 denotes a coating layer, and the coating layer 12 is a base material of an inorganic material (metal such as copper, iron, titanium, aluminum alloy, stainless steel, or glass) that is bent and bent into a desired panel shape. 11 is formed on the surface.

Note that, as in the case of the first embodiment, the surface of the base material 11 is roughened by forming minute concaves and convexes by plastic deformation.

Further, as in the case of Embodiment 1, 18 is a pattern sheet, and the pattern sheet 18 is formed on the surface of the resin sheet 13 made of a transparent thermoplastic resin and the resin sheet 13. It consists of a colored pattern 16.

The coating layer 12 is obtained by applying a coating agent called organosilane to the surface of the base material 11, and the film thickness of the coating layer 12 is sufficiently thin with respect to the unevenness of the surface of the base material 11. .

[0033] Examples of the organosilane used as the material of the coating layer 12 include butyltrimethoxysilane, bi-triethoxysilane, burtris (j8 methoxyethoxy) silane, 13- (3,4 epoquine, γ-glycid. Xylpropylmethyl jetoxysilane, γ-glycidoxypropyltriethoxysilane, γ-glycidoxypropylmethyldimethoxysilane, γ-methacryloxypropyltrimethoxysilane, γ-methacryloxypropyltriethoxysilane, γ-methacryloxy pill _{Methyljetoxysilane} , Ν-β (aminoethyl) _{Ί -aminopropylmethyljetoxysilane} , Ν-β (aminoethyl) γ -aminopropyltriethoxysilane, Ν-β (aminoethyl) γ -aminopropyltri Methoxysilane, γ-aminopropyltrimethoxysila Γ-aminopropyltriethoxysilane or γ-mercaptopropyltrimethoxysilane It is.

[0034] A coating layer forming process for forming the coating layer 12 will be described.

First, the substrate 11 whose surface is roughened is immersed in a bath of acetone, surfactant, alcohol, or the like, which is set to room temperature to a boiling point, for about several minutes to ten and several minutes. Degrease.

Next, the degreased substrate 11 is washed with water by spraying tap water or immersing it in tap water. In addition, the temperature of the tap water at this time is about room temperature.

Subsequently, the substrate 11 is washed with water by a method such as spraying with pure water or immersion in pure water. In addition, the temperature of the pure water at this time is also about room temperature.

After rinsing with pure water! / Soaking, the substrate 11 is dried for a few minutes to a few dozen minutes.

[0035] After the base material 11 is dried, the base material is sprayed, for example, by dipping liquid organosilane diluted to about 1 to 10% using a low boiling point material such as alcohol or ether. 11 roughened coating on the surface.

Thereafter, the drying process is started, and the substrate 11 coated with the organosilane is dried in a drying chamber at room temperature of about 50 to 100 degrees for several minutes for several tens of minutes. By the above method, the coating layer 12 is formed on the roughened surface of the substrate 11.

Here, FIG. 13 is a diagram for explaining the action of the organosilane contained in the coating layer 12.

Organosilane has a structure having an inorganic silyl group and an organic functional group. The organic functional group is, for example, an amino group, a methacryloxy group, or a vinyl group. For example, when a steel plate is used as the base material 11, the molecular arrangement on the base material 11 side is such that Fe and O are alternately arranged (acid iron iron), and a hydroxyl group is bonded to the surface. .

Further, for example, a carboxyl group or an ester carboxylic group is present on the end surface on the side of the resin sheet 13 made of thermoplastic resin.

FIG. 14 is a view showing a state in which the base material 11, the coating layer 12, and the resin sheet 13 made of thermoplastic resin shown in FIG. 13 are combined.

The organic functional group of the organosilane reacts with the carboxyl group or ester carbonyl group of the resin sheet 13 made of thermoplastic resin to discharge alcohol and moisture, For example, a chemical bond is formed in a form that produces an amide.

Further, the inorganic silyl group reacts with the hydroxyl group on the surface of the substrate 11 to discharge the alcohol and form an organic bond, for example, in the form of oxygen sharing.

By these chemical bonds, the resin sheet 13 made of an organic thermoplastic resin is firmly bonded to the base material 11 of the inorganic material via the coating layer 12.

[0038] In addition, unlike general adhesives and coating films, organosilane works effectively to the extent that a monomolecular layer covers the surface of the substrate 11, so that the physical shape of the surface of the substrate 11 is reduced. It has become a substantial influence.

As described above, in the method for producing a decorative member, the coating layer 12 containing organosilane is used, so that the pattern sheet 18 is further strengthened on the inorganic base material 11 through the resin sheet 13 and the coating layer 12. And evenly combined.

Further, since the surface of the base material 11 is roughened, the surface area of the base material 11 is increased, and the pattern sheet 18 can be bonded more firmly.

As described above, in the decorative member according to the present embodiment, in the decorative member according to the first embodiment, the coating layer 12 further containing organosilane is formed on the roughened surface of the base material 11. It is characterized by that.

The decorative member manufacturing method according to the present embodiment is the same as the decorative member manufacturing method according to the first embodiment, except that the roughened surface of the substrate 11 contains organosilane before the pattern sheet arranging step. It has a coating layer forming process for forming a single layer! /.

Accordingly, the resin sheet 13 made of organic thermoplastic resin is uniformly and firmly bonded to the inorganic base material 11 via the coating layer 12, so that the effect of the first embodiment is achieved. In addition, the large-area pattern sheet 18 can be bonded to the base material 11 more firmly.

Industrial applicability

[0040] According to the present invention, a pattern sheet having a large area can be firmly bonded to a substrate made of an inorganic material without using an adhesive, and the manufacturing process can be simplified and the manufacturing time can be reduced. This is useful for providing a decorative member that can be significantly shortened or a method for manufacturing the decorative member. Brief Description of Drawings
