JP6432757B2 - Pseudo-colored transparent plate and manufacturing method thereof - Google Patents

Description

  The present invention relates to a pseudo-colored transparent plate and a method for producing the same, and more particularly to a pseudo-colored transparent plate and a method for producing the same, in which colored particles are attached to the surface of a glass plate to perform pseudo-coloring.

  Glass is solidified without rapidly becoming a crystal by rapidly cooling various metal silicates, and constitutes a transparent body.

  Various glasses such as soda lime glass, potash lime glass, lead glass, borate glass, and quartz glass are known depending on the material. In order to color such glass, a metal oxide which becomes an impurity is added as disclosed in, for example, Japanese Patent Application Laid-Open No. 2012-193094. As such a metal oxide, manganese (purple), nickel (blue purple), neodymium (red purple), cobalt (blue), chromium (green), selenium (red), or the like is used. Since the glass is colored when the molten material is cooled, the glass is formed as one color and cannot be colored after being cooled and solidified. Moreover, in one glass body, it cannot color in a different color in each location.

  Another method for coloring the glass plate later is coloring with a thin film as disclosed in Japanese Patent Application Laid-Open No. 2007-297235, for example. That is, a thin film made of ceramic, metal or the like is formed on the surface of a glass plate by a method such as vapor deposition, sputtering, or ion plating. By adjusting the kind and thickness of the thin film as described above, it is possible to adjust the light transmittance or reflectivity, and in particular, it is possible to produce a light-functional translucent glass. However, coloring with such a thin film requires large-scale equipment and has the disadvantages that partial color adjustment cannot be performed.

Main invention of the present application, SQLDESC_BASE_TABLE_NAME This adhesive formed via the adhesive film two transparent glass plate, a glass faceplate that is used as a face plate of apartments handrail,
An optically transparent medium is formed by forming minute irregularities on the surface of one of the two glass plates in contact with the adhesive film to form a rough surface and attaching colored particles to the rough surface. The present invention relates to a pseudo-colored transparent plate in which the colored particles are enclosed with the adhesive film so as to cover the rough surface of the one glass plate.

  Here, the adhesive film may be a transparent PVB (polyvinyl butyral) resin film. The adhesive film may be a transparent EVA (ethylene-vinyl acetate copolymer) resin film. The colored fine particles may be pigment particles.

  Further, a predetermined pattern may be formed according to the properties of the rough surface or the shape of the processed region. Further, the gradation may gradually change as the pattern moves from one end of the glass plate to the other end. The pattern may be a pattern in which streaks extending in a predetermined direction are formed in parallel to each other. The pattern may be a pattern that is uniformly distributed over the entire surface of the glass plate.

The invention relating to the manufacturing method is a method of manufacturing a glass face plate in which two transparent glass plates are bonded via an adhesive film,
Forming a rough surface on the surface in contact with the adhesive film of one of the two glass plates to form a rough surface;
Attaching colored fine particles to the rough surface of the rough surface;

The colored particles are enclosed with the adhesive film so as to cover the rough surface of the one glass plate.

  Therefore, according to such a pseudo-colored transparent plate, a rough surface is formed by forming irregularities on the surface of the glass plate, and the transparent adhesive film constituting the optical transparent medium is adhered by attaching colored particles to such a rough surface. By doing so, it becomes possible to enclose the colored fine particles to obtain a pseudo-colored transparent plate. Therefore, the glass plate can be colored by a very simple method.

  Here, various colors can be colored by changing the color of the colored fine particles. Moreover, various patterns can be arbitrarily formed on the surface of the glass by changing the rough surface to a shape such as gradation, parallel streaks, or a uniform pattern.

  The present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows a glass plate 10 for coloring according to the present embodiment. As the glass plate 10, glass plates having various thicknesses can be freely selected according to the purpose. Moreover, various glass plates can be used for the types of glass plates.

  FIG. 2 shows an apparatus for roughing the surface of such a glass plate and a state in which roughening is performed. An injection gun 11 is disposed above the glass plate 10, and abrasive particles are injected while scanning the injection gun 11 along the surface of the glass plate 10 in the horizontal and vertical directions. Thus, the rough surface processing is performed on a predetermined region of the glass plate 10. The injection gun 11 supplies abrasive grains prepared in advance from a supply device (not shown) so as to be injected from the injection port at the tip of the injection gun 11. By controlling the state of injection at this time, it is possible to perform roughing so as to form various patterns on one surface of the glass plate 10.

  FIG. 3 shows a rough surface 13 having a gradation pattern formed by the apparatus shown in FIG. That is, while the rough end of the rough surface is severely formed on the right end side of the glass plate 10, the left end side is close to the initial transparent and smooth state of the glass plate 10, and the roughness gradually changes. It is like that.

  The gradation as described above may be changed sequentially in synchronization with the scanning of the spray gun 11 by the spray pressure of the abrasive grains by the spray gun 11. Alternatively, the spray time by the spray gun 11 may be sequentially changed according to the state of the surface of the glass plate 10. Alternatively, the gap between the nozzle at the tip of the spray gun 11 and the glass plate 10 may be changed sequentially when the glass plate 10 is scanned. The gradation roughening as shown in FIG. 3 is performed by any of these various methods.

  Pigment particles are applied to the surface of the roughened surface 13 and thus the surface of the roughened surface 13. Here, the pigment is a powder used for coloring, which is insoluble in water or oil. Particulate pigments selectively absorb light of a specific wavelength, thereby changing the reflected or transmitted color. The coloration process of almost all pigments excluding fluorescent pigments is a process physically different from luminescence such as fluorescence or phosphorescence that emits light. Pigments are classified into inorganic pigments, organic pigments, lake pigments, fluorescent pigments and the like based on their chemical classification. The organic pigments are further classified into polycyclic pigments and azo pigments. Here, the pigment applied to the glass plate 10 to be colored does not have to be a specific pigment, and may be arbitrarily selected as long as it is a material capable of expressing a target color.

  Then, after the pigment powder is applied, the excess pigment particles are wiped off, so that the pigment particles remain in the concave portions of the rough surface (see FIG. 6). In such a state, as shown in FIGS. 4 and 5, another glass plate 19 and the roughened glass plate 10 are bonded to each other via the adhesive film 18. In addition, about the glass plate 19 located in the upper side, both the upper surface and the lower surface are in a smooth state, and are smooth glass plates.

  And the pigment particle remains in the bottom part of the recessed part of the unevenness | corrugation 20 by which the roughened surface of the glass plate 10 was processed, and the excess pigment particle | grains 14 which float on the surface are wiped off and removed. After that, when the transparent adhesive film 18 is adhered, the adhesive film 18 constitutes a transparent medium, and this medium prevents the irregular reflection of the rough surface 13, and the pigment particles 14 are encapsulated inside the glass plate 10. An appearance like this is produced. As such a transparent adhesive film 18, PVB (polyvinyl butyral) is preferably used. Alternatively, EVA (ethylene-vinyl acetate copolymer) may be used. Such a transparent adhesive film 18 constitutes an adhesive means for the glass plates 10 and 19 on both sides and constitutes an optically transparent medium for the pigment particles 14. Thus, the appearance is as if the pigment particles 14 are embedded in the glass plates 10 and 19.

  The effect of the optical medium by the transparent adhesive film 18 is the same principle as that when a water droplet is dropped on the surface of the frosted glass, for example, the rough surface of the frosted glass appears transparent by the water droplet. The present invention is characterized in that the glass plates 10 and 19 on both sides are bonded to such pigment particles 14 via an adhesive film 18 constituting an optically transparent medium.

  As shown in FIG. 3, when the rough surface 13 of the glass plate 10 is gradation and the unevenness of the rough surface is gradually weakened from the right end to the left end, coloring is formed with gradation as shown in FIG. become. For example, when blue pigment particles are applied to the uneven portion 20 of the rough surface 14, as shown in FIG. 7, a gradation color is formed such that the blue color is dark at the lower end side and gradually becomes lighter as it goes upward. Is done.

  FIG. 8 shows a case where a colored portion 25 composed of diagonal stripes is formed in place of the gradation as described above. Such coloring is performed by applying a polyurethane mask to a portion of the surface of the glass plate 10 which is not a roughened region, and a spray gun 11 is applied to the glass plate 10 having such a mask. By performing the abrasive processing, a rough surface similar to the diagonal stripes of the colored portion 25 is formed. Accordingly, when the pigment particles 14 are applied later and placed in the concave portions of the rough surface unevenness 20, coloring of an oblique stripe pattern can be obtained.

  In FIG. 9, such a striped pattern is formed in the vertical direction, and the colored portion 25 forms a plurality of vertical stripes parallel to each other. Here again, in a portion other than the colored portion 25, a polyurethane mask is applied to the surface of the glass plate 10, and the rough surface processing by the abrasive grains is formed in a striped pattern.

  In FIG. 10, a circular pattern is distributed almost uniformly over the entire surface, instead of the colored portion composed of the above-described stripe pattern. Here, the circular patterns have various sizes, and large, medium, or small patterns coexist. Further, the various pattern portions of these large circle, medium circle, or small circle are uniformly distributed over the entire surface of the glass face plate 21. Such a colored portion 25 is also achieved by carrying out the abrasive grain processing while masking with polyurethane.

  FIG. 11 shows a state where the glass face plate 21 having a colored gradation as shown in FIG. 7 is assembled on the veranda of the apartment. The three glass face plates 21 are juxtaposed in the lateral direction, and a headboard 30 is attached along the upper surface of the three glass face plates 21. A vertical rod 31 is arranged in the vertical direction between the three glass face plates 21. Further, a lower rod 32 is attached to the lower ends of the three glass face plates 21. And the assembled handrail is connected with the support | pillar 33 attached to the back side, and this support | pillar 33 fixes to the front edge part of the veranda of an apartment. It should be noted that the number and size of the glass face plates 21 constituting the handrail of the veranda can be arbitrarily changed according to the size of the attached veranda.

  FIG. 12 is a handrail of a condominium veranda similar to FIG. 11 using a glass face plate 21 as shown in FIG. 9 in which a pattern composed of vertical stripes is formed. Here, a streak pattern is formed on each face plate 21 by colored portions 25 in the vertical direction, the headboard 30 is attached to the upper end, the vertical rod 31 is attached between the face plates 21, and the lower rod 32 is attached to the lower end of the face plate 21. . And it fixes to the front edge of a veranda by the support | pillar 33 of the back side.

Example 1
Two sheets of glass with a thickness of 4 mm made of soda glass are prepared, and one of the glass sheets 10 is sprayed with abrasive grains containing aluminum from a spray gun 11 using an apparatus as shown in FIG. As a result, a gradation rough surface 13 as shown in FIG. 3 was formed on the surface of the glass plate 10. For the rough surface of gradation, the spray pressure by the spray gun 11 was changed. The gun 11 is configured so that the injection pressure is adjusted to a maximum of 1.0 MPa, and at first, the abrasive particles are injected at an injection pressure of 0.5 MPa in the length direction of the glass plate 10. The gradation rough surface 13 was formed so as to reduce the injection pressure to 0.01 MPa when moving along. And after applying the powder of a blue inorganic pigment to the rough surface 13 of such a glass plate 10, it wiped with the cloth. Thereafter, as shown in FIG. 4 and FIG. 5, it was joined to a normal glass plate 19 that was not roughened through a PVB adhesive film 18 that was transparent and had a thickness of 0.38 mm. Since the adhesive film 18 is transparent and constitutes an optically transparent medium, a blue gradation glass face plate 21 is obtained.

  Such a glass face plate 21 was used as a handrail faceplate 21 for a condominium veranda as shown in FIG. 11, thereby assembling a handrail for a condominium veranda. This veranda has a blue gradation on the lower side of the glass face plate 21 and a transparent gradation on the upper side.

Example 2
The area | region except the area | region which forms the rough surface 13 in FIG. 8 was covered on the surface of the glass plate similar to the glass plate 10 used in Example 1 with the polyurethane mask. And the abrasive grain was sprayed to the whole surface with the spray gun 11 shown in FIG. The area without the mask was roughened by abrasive grains sprayed from the spray gun 11. After the rough surface processing, the mask was removed, and a blue pigment was applied to the entire surface of the glass plate 10 and then wiped with a cloth. Then, as shown in FIG. 4 and FIG. 5, a normal glass plate 19 that was not roughened was joined with the same PVB adhesive film as the adhesive film 18 shown in Example 1. As a result, a glass face plate colored diagonally as shown in FIG. 8 was obtained.

Example 3
In FIG. 9, a polyurethane mask is applied to a portion corresponding to the region other than the colored portion 25, and in this state, the same rough surface processing as in the embodiment is performed by the apparatus shown in FIG. 2, so that the polyurethane mask is not formed. In the region, colored stripes 25 in the vertical direction were formed. And using such a glass faceplate 21, it was used as the glass faceplate 21 of the veranda of an apartment as shown in FIG. The glass face plate 21 has a veranda with a unique appearance because a striped pattern made of coloration in the vertical direction is formed.

Example 4
Next, the thing of the form shown in FIG. This glass face plate 21 is a surface of the glass plate 10 and a polyurethane mask is applied to a region excluding the colored portion 25, thereby forming a rough surface on the surface of the glass plate 10 corresponding to the colored portion 25. . Then, after removing the polyurethane mask, a red pigment is applied and then wiped with a cloth. Then, as shown in FIG. 4 and FIG. 5, it is bonded to a normal glass plate 19 with a transparent PVB adhesive film. Thus, a glass face plate 21 was obtained. As shown in FIG. 21, in this glass face plate 21, red pigment remained in the roughened portion, and thereby, a glass face plate 21 pseudo-colored in red was obtained.

  While the present invention has been described with reference to the illustrated embodiment, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical idea of the present invention. For example, various changes can be made to the shape of the pattern formed by the rough surface 13 in the above embodiment. Further, the present invention can be applied not only to a condominium veranda, but also to a partition plate in a building.

  The present invention can be used as a handrail for a veranda in an apartment.
