In order to achieve the above object, the coloring process of the present invention will be described in detail by Examples.

Example 1

1. Coloring process

As shown in FIG. 2, the urethane coating layer 200a, which is a screen-printed shape, is colored on the surface of the lamp cover glass 100 using various urethane paints.

Of course, before the coloring process to clean the lamp cover glass to dry and then perform the following coloring process.

As shown in FIG. 2, the coating layer 200a of the urethane paint is applied to the surface of the cover glass 100 with a thickness of 0.2 mm to 0.5 mm, and the urethane paint has a low shrinkage during coating, which is excellent in moldability and buffered. In the process of polishing the surface of the cover glass 100, the urethane is also used in the process of spraying the sand 400 for 15 to 20 seconds with the air pressure of the 30 hp (HP) to 60 hp (HP) air compressor 300 during the process of polishing the surface of the cover glass 100. Since the coating layer 200a does not peel, a urethane paint is used.

In addition, by using an inorganic ceramic paint instead of the urethane paint to implement in order to block the harmful components emitted from the fluorescent lamp in advance to create a comfortable living environment, in the embodiment of the present invention by adjusting the molar ratio of silicic acid and alkali Using the prepared silicate as a binder, it is proposed a composition coating having improved functionality by adding a powder which can improve acid resistance, corrosion resistance, chemical resistance, antibacterial property, nonflammability, light resistance, etc. have.

That is, in the present invention, the molar ratio (MR) of silicic acid and alkali (nSiO 2 / K 2 O) is 2.5 to 7.0, and 5 to 40 parts by weight of a substance that emits far infrared rays and an anion are emitted based on 100 parts by weight of a silicate which functions as a binder. It is characterized in that the inorganic ceramic paint prepared by using a paint containing at least one functional material selected from 1 to 30 parts by weight of the material, 0.5 to 10 parts by weight of the photocatalyst powder and 0.1 to 5 parts by weight of the antibacterial powder is used.

Herein, when the molar ratio of the carbo silicate is 2.5 or less, the degree of bonding is inferior in molecular water and there is little water resistance. In addition, when the molar ratio is more than 7.0, intermolecular bonding is increased, so that the water resistance can be greatly improved. Since it takes too large, there is a problem without economics.

Among the functional materials added to the carry silicate binder as described above, the far-infrared radiating material is ceramic powder such as chorionic wool having a far-infrared emissivity of 85% or more at room temperature of 40 ° C, such as quartz-monzonite, gneiss and pyloric tuff. It consists of a ceramic powder containing one or more selected from the group of natural minerals.

In addition, the anion-releasing material is, for example, tourmaline, loess, amethyst, raw ore, bamboo charcoal, Uwang wang, guinea stone, obsidian, ganban stone, light mineral stone, lava, precious stone selected from one or more natural stone material or algae coal, It consists of a powder of at least one charcoal material selected.

The particle size of these far-infrared powders or anion powders is 1-50 탆, and in particular, in the case of anionic powder, the addition ratio is determined within 1-30 parts by weight so as to release 300-2000 Ion / cc. At this time, substances with a small amount of anion released, such as tourmaline, are injected to the maximum within the allowable range, while high anions, such as heat, are expensive, while expensive materials mix only a minimum amount with the anion mineral. Determine and add.

2. Drying process

The colored cover glass 100 is naturally dried at room temperature for 50 to 60 minutes to completely dry the urethane coating layer 200a.

3. Sanding process

As shown in FIG. 3, the urethane coating layer was sprayed on the surface of the lamp cover glass 100 by spraying sand 400 for 20 seconds to 30 seconds with an air pressure of 30 hp (HP) to 60 hp (HP). Sanding treatment is performed so that minute scratches appear on the surface of the cover glass 100 except for 200a.

In the sanding processing process, since the glass is transparent, the shape of the lighting light emitting body (fluorescent lamp, etc.) installed in the lighting fixture is passed through the transparent glass as it is, and the light is emitted directly, thereby directly contacting the eyes of the person, which increases eye fatigue. The shape of the inside of the light and the shape of the light emitting body (fluorescent lamp) are reflected as it is, the beauty of the lighting fixtures fall, so to prevent this, by sanding processing by using sand to have an opaque glass, which causes the light emitting body (fluorescent lamp, etc.) The light from the light is scattered through the opaque glass, giving off a soft glow, adding to the beauty of the lighting fixtures.

4. Assemble the cover glass 100 of the finished product, as shown in FIG.

In the method of coating the printed matter, screen printing through a roller and screen printing through a transfer paper may be performed.

In addition, instead of performing the processes of 2. and 3., the surface of the cover glass 100 may be colored by screen printing using a urethane paint having an opaque color.

At this time, the paint used may be a urethane, epoxy, PE, PP, PVC, and the like.

Therefore, a method of coloring the surface of the cover glass 100 through screen printing using the opaque urethane paint, which will be described in detail, will be described below.

[Example 2]

As a transfer paper 200b having a color or pattern, a protective layer for protecting the printing layer with a UV curable paint was used, and a fast-drying acrylic urethane material was used as an adhesive for bonding the transfer paper 200b to the cover glass 100 surface. The pearl was mixed in consideration of the beautifulness of the appearance, and a super fast drying type acrylic urethane material was used as the finishing coating material for the backside treatment after the transfer paper was bonded.

Glass has the advantages of flame resistance, scratch resistance, and abrasion resistance, and has another advantage of not only being easily contaminated but also easy to clean.However, glass can be broken by impact, so it is used as an external finishing material for home appliances or furniture. It is not easy to do.

As the transfer paper 200b having a color or pattern in the present invention, a UV-curable paint coated with a so-called UV varnish on the market was used, which is a UV-curable paint having excellent abrasion resistance, scratch resistance, chemical resistance, and the like. This is because it has advantages as a layer.

The transfer paper 200b is formed by applying a UV varnish as a protective layer on one surface of a polyester film used as a release paper to be peeled off after transfer and printing a desired color or pattern thereon to form a printing layer, and the cover glass 100 surface. After being transferred to the release paper, the release paper is peeled off, leaving only the print layer and the UV varnish protective layer.

As an adhesive for bonding the transfer paper 200b to the surface of the cover glass 100, a mixture of pearl and a transparent quick-drying acrylic urethane material was used. This is because it should be transparent so that the pattern can be seen, and here, pearl was mixed in consideration of the beauty of the appearance.

The adhesive actually used in the present invention is already commercialized and commercially used, and pearl is mixed with what is sold under the name of Christian transparent (GL).

On the other hand, in the present invention, as a finish coating material for forming a protective layer of the transferred color or pattern by backside treatment using the transfer paper (200b) after the transfer paint, a non-transparent colored paint of opaque general paint or opaque super fast-drying acrylic urethane material may be used. In the case of acrylic urethane, like the protective layer of the transfer paper 200b, it is a UV-curable material, and has a high heat resistance, chemical resistance, abrasion resistance, and corrosion resistance. The purpose is to prevent light from being transmitted and affecting the beautifulness of the printed layer color or pattern due to the nature of being used on the rear surface.

The method of coloring the surface of the cover glass 100 of the present invention, as shown in Figures 5, 6 and 7, washing step to clean the glass surface to be colored, and heating maintained at a temperature of 110-180 ℃ The transfer paper 200b is pressed and transferred onto the upper surface of the cover glass 100 by using the roller 500, and is sequentially formed in a drying step through a transfer step of transferring a color or pattern.

In addition, in order to prevent the coating layer coated with the transfer paper 200b on the surface of the cover glass 100 from being peeled off, an adhesive may be coated on the surface of the cover glass 100 to be used.

As the adhesive, pearl was mixed with Kristen Transparent (GL) (Construction Chemicals, Inc., Korea).

The transfer step of forming a color or pattern by transferring the transfer paper 200b to the upper surface of the adhesive layer formed in this way, such a transfer step is performed by using a heating roller 500 maintained at a temperature of 110-180 ℃ Pressing and transferring the transfer paper 200b to the upper surface of the painting.

In the present invention, the transfer paper 200b having a color or pattern is coated with a UV curable paint, called UV varnish, as a protective layer in the market, thereby providing wear resistance, scratch resistance, chemical resistance, and the like.

The transfer paper 200b is formed by applying a UV varnish as a protective layer on one surface of a polyester film used as a release paper to be peeled off after transfer and printing a desired color or pattern thereon to form a printing layer.

The completed lamp cover glass 100 of the present invention, by being able to apply a variety of colors or patterns basically can not only have a beautiful appearance, but also a protective layer consisting of a UV curable material and the upper coating double printed layer By protecting the, it is possible to maximize the effect of preventing the print layer from being damaged by heat, chemicals, abrasion, and the like.

The lamp cover glass 100 of the present invention manufactured through the coloring process as described above is to produce a cover material 100, a sanding process on the surface except the shape of the urethane paint is colored, the lamp (10) Even if you use it for a long time, it is possible to provide a lighting that always gives an elegant and beautiful feeling without discoloring or erasing.
