Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is capable of forming a multicolored and colorful pattern on a glass substrate, and is therefore capable of forming a marble pattern or the like by a simple operation. The present invention relates to a method for patterning a glass substrate from which an exterior material can be obtained.

[Prior art] Conventionally, as an interior or exterior material for a building having a marble pattern or the like, a marble pattern is formed on paper or a plastic sheet by printing, and this is heated and compressed by a normal method of forming a laminate. Laminated molding. The marble pattern has been obtained by drawing an original image and printing it, or photographing a real marble and printing it.

[Problems to be Solved by the Invention] However, these conventional building interior materials or exterior materials having a marble pattern or the like are printed on a paper or plastic sheet, so that they are planar and There is a disadvantage that the marble pattern becomes uniform. Further, since it is necessary to go through printing and lamination molding steps, it is suitable for mass production, but has a drawback that it is not suitable for easily obtaining a desired pattern.

[Means for Solving the Problem] Therefore, the method of patterning a glass substrate according to the present invention uses a glass substrate as a substrate and attempts to solve the above-mentioned drawbacks by firmly fixing a paint to the glass substrate. is there.

That is, the method for patterning a glass substrate according to the present invention comprises a combination roller in which a surface modifier containing a silane-based compound is undercoated on a glass substrate, and one end of each of a number of small pieces of an elastic sheet is planted. Use,
By rotating the tip of the elastic sheet at a speed that can be beaten by centrifugal force, various patterns are drawn on the glass substrate with a paint, and then coated with an epoxy resin-based protective film.

[Operation] According to the method of patterning a glass substrate of the present invention, a pattern can be formed on a glass substrate by various methods, and not only a marble pattern but also various patterns can be formed.

And, by attaching the patterned glass substrate to the wall surface with the patterned side as the back surface, the sense of rigidity of the glass substrate can be utilized as it is, and an atmosphere closer to marble can be obtained, and the surface It is possible to obtain an interior or exterior material for a building that is not easily scratched.

Example Next, an example of a method for patterning a glass substrate according to the present invention will be described with reference to the drawings.

1 and 2, reference numeral 1 denotes a glass substrate, on which a surface modifier containing a silane compound (Nippe primer modifier A, trade name of Nippon Paint Co., Ltd.) is undercoated. Have been. It is desirable that the transparent underlayer 2 made of the surface modifier be obtained by brush or roller coating at a coating amount of 0.05 to 0.10 kg / m2 per application. After application, it is necessary to dry it so that the water content becomes 10% or less.

As the glass substrate 1, it is desirable to use frosted glass in which the back surface on which the underlayer 2 is formed is frosted by spraying with gold sand or chemical treatment. The opacity of the matte surface 5 disappears when the underlayer 2 is formed.

Various patterns can be drawn on the transparent base layer 2 with paint. As a material for forming the pattern layer 3, a paint (Terapel Color or Terapar Enamel, trade name of Nippon Paint Co., Ltd.) mainly containing an isocyanate-curable non-yellowing urethane resin is desirable. The pattern layer 3 is desirably obtained at a coating amount of about 0.13 to 0.15 kg / m2 per one time. After application, it is necessary to dry it so that the water content becomes 10% or less. When the pattern layer 3 is formed in this manner, the pattern layer 3 can be seen through from the surface of the glass substrate 1 through the transparent underlayer 2 which has become transparent as described above. As the pattern of the pattern layer 3, natural patterns such as a marble pattern, a pattern similar to other stone materials, and a flowing pattern can be obtained.

It is necessary to cover the obtained pattern layer 3 with an epoxy resin-based protective film 4.

The present invention is also characterized in that the pattern layer 3 is obtained by a combination roller. The combination roller 11 shown in FIGS. 3 and 4 has a shaft 16 and a roller body 12 that rotates around the shaft 16 from the center thereof.
And the cardboard 13 attached around the roller body 12
And cold gauze 14 stuck on the surface of cardboard 13 and cold gauze
14 and an elastic sheet 15 implanted on the surface. Note that, instead of the cold gauze 14, a microglass-treated cloth can be used.

Reference numeral 17 denotes an arm extending from one end of the shaft 16 in a direction perpendicular to the roller body 12, and a handle 18 for manual work is provided at the end.

As the material of the elastic sheet 15, a rubber sheet, a flexible plastic sheet, or a fiber having a diameter of about 0.5 mm or more can be suitably used. In order to implant the elastic sheet 15 on the surface of the cold gauze 14, means such as sewing, hooking, bonding with an adhesive, and binding with a octopus thread or tex can be employed.

By appropriately selecting the shape, size, planting position, and interval of the elastic sheet 15, the pattern repetition mode can be adjusted. 21 is a hook.

The shape of the elastic sheet 15 is shown in FIGS.
Various shapes such as those shown in (p) can be employed, and a repetitive pattern with a taste can be obtained.

When applying the pattern layer 13 using the combination roller, the combination roller 11 is pressed against a paint tank in which the paint is spread to a certain thickness, and the roller is pressed.
It is only necessary to apply the paint to the surface of the substrate 11 and rotate the combination roller 11 on the coated surface subjected to the base treatment. At that time, the combination roller 11 needs to be rotated on the coating surface at a speed at which the tip of the elastic sheet 15 is beaten by centrifugal force. When a predetermined pattern is formed in a certain rotation direction, the combination roller 11 is rotated in a direction different from the above rotation direction, for example, a right angle direction. By doing so, an even and repeated pattern can be obtained.

When a multicolor pattern is to be obtained, a different paint may be overcoated on the coated surface using another combination roller 11.

A more luxurious coated surface can be obtained by holding metal powder, mica powder, other reflective materials, and the like on the base layer 2 and performing the coating treatment after the base is cured.

Further, while supplying the substrate to be continuously combined, the combination roller 11 is rotated at a speed at which the tip of the elastic sheet 15 is beaten by centrifugal force on the substrate, thereby performing combination painting on the substrate. Exterior and interior boards of various sizes can be manufactured.

At this time, it is also possible to apply a suitable combination of patterning means such as brushing, spraying, and patterning with a patterning roller.

[Effects of the Invention] According to the method for patterning a glass substrate of the present invention, it is possible to pattern a glass substrate by various methods, and it is possible to form not only a marble pattern but also various patterns.

And, by attaching the patterned glass substrate to the wall surface with the patterned side as the back surface, the sense of rigidity of the glass substrate can be utilized as it is, and an atmosphere closer to marble can be obtained, and the surface It is possible to obtain an interior material or an exterior material for a building that is not easily damaged.
