In addition, the static eliminator of the static eliminator 210 may electrically neutralize the reflecting plate 70 by decomposing molecules in the air using X-rays to generate air ions.

Of course, it is not limited to this, Any means can be used as long as it can electrically neutralize the reflecting plate 70. For example, a static eliminator using corona discharge can be used.

Alternatively, the static eliminator of the static eliminator 210 may generate static electricity to remove foreign substances on the reflective plate 70.

The undercoat coating part 220 forms a undercoat coating layer by applying a primer to a surface of the reflecting plate 70 electrically neutralized by the antistatic agent 210.

As shown in FIG. 3, the undercoat coating part 220 includes a first chamber 222, a first pedestal 224 spaced a predetermined height from an inner bottom surface of the first chamber 222, and A first transfer table 226 provided on the inner side of the first chamber 222 and transported in the horizontal (X) and vertical (Y) directions, and provided on one side of the first transfer table 226. The first nozzle 228 is sprayed with a primer so that the primer coating layer is formed on the reflecting plate 70 by receiving the primer provided from.

The first chamber 222 is hermetically closed and provided to open and close a door (not shown) on one side thereof, and the door is closed during the process of forming the undercoat layer.

When the primer is sprayed by the first nozzle 228 by mounting the reflector 70 on the first support 224, a part of the first support 224 is applied to the surface of the reflector 70, and a part of the first chamber 224. 222 is meshed to be collected on the bottom surface.

The first transfer table 226 transfers the first nozzle 218 fixed to one side in the horizontal (X) and vertical (Y) directions to form a bottom coating layer by applying a primer to the reflecting plate 70. .

The primer is preferably an ultraviolet paint. Of course, the present invention is not limited thereto, and primers may be appropriately selected and used depending on the material of the reflecting plate.

The ultraviolet paint not only improves the adhesion strength with the reflector, but also shortens the curing time, thereby reducing defect rate and improving productivity.

In addition, the thickness of the undercoat layer of the undercoat portion 220 is preferably 20 ~ 30㎛.

When the thickness of the undercoat layer is less than 20 μm, a part of the undercoat layer may be dropped during the pretreatment of the pretreatment unit 240, which will be described later. do. Therefore, the thickness of the undercoat portion 220 is preferably 20 ~ 30㎛.

As shown in FIG. 4, the first drying unit 230 dries the undercoat layer coated on the reflective plate 70 at a predetermined thickness.

In addition, the first drying unit 230 includes a second chamber 231, a first infrared drying chamber 232, an ultraviolet irradiation chamber 234, and a second infrared drying chamber inside the second chamber 231. A second transport table (236) is arranged to be sequentially partitioned, and provided below the second chamber (231) and for conveying the reflecting plate 70 to the respective drying chambers (232, 234, 236) ( 238).

The second chamber 231 is hermetically sealed, and has an entrance port through which the reflection plate 70 enters and an exit port through which the reflection plate 70 is discharged at the other end, and a door is opened and closed at each entrance port and the discharge port.

In addition, a partition wall 239 is provided inside the second chamber 231 to partition each of the first and second infrared ray drying chambers 232 and 236 and the ultraviolet irradiation chamber 234. In some cases, the partition wall 239 may be omitted.

The first and second infrared ray drying chambers 232 and 236 use infrared rays as a heat source, and the infrared rays penetrate the bottom coating layer to penetrate the reflecting plate 70 by a predetermined depth, and thus, the first and second infrared ray drying chambers 232 and 236 are formed from the inner surface of the reflecting plate 70. Dry secondly. Accordingly, the adhesion strength between the reflective plate 70 and the undercoat layer can be improved.

In addition, the ultraviolet irradiation chamber 234 irradiates ultraviolet rays to quickly cure the ultraviolet coating, which is a undercoat coating layer.

The present invention is not limited thereto, and any means may be used as long as the reflective plate 70 can be easily transferred to the respective drying chambers 232, 234, 236.

The pretreatment unit 240 may form fine irregularities on the hard coat layer to improve adhesion of the coating layer.

That is, the pretreatment unit 240 sprays tin chloride (SnCl 2 ), which is a surface modifier, forms a fine concavo-convex surface on the undercoat layer, and then removes the residue by washing with pure water (H 2 O).

In some cases, a removal operation for removing residue or water remaining in the reflector 70 may be performed. In this case, it is preferable to use compressed air.

The film treatment unit 250 forms a silver or black film on the surface of the pre-treated reflective plate 70.

The film treatment unit 250 simultaneously sprays each of the silver solution and the reducing agent onto the surface of the reflector 70 to form a silver or black film by chemical reaction.

The silver liquid undergoes the following chemical reaction.

AgNO 3 (silver nitrate) + 3 NH 3 (ammonia) + H 2 O (water) = Ag (NH 3 ) 2 OH + NH 4 NO 3

That is, the coating treatment liquid applied to the reflecting plate 70 through the fourth and fifth nozzles 328 and 329, respectively, by chemical reaction.

2Ag (NH 3 ) 2 OH + 2NH 4 NO 3 + RCHO = 2Ag (precipitation) + RCOOHNH 4 (discharge) + 3NH 4 (discharge) + H 2 O (discharge), the precipitated 2Ag of the reflector 70 To form a film.

At this time, black electrons are formed when electrons are obtained (+), and silver mirrors are formed when electrons are lost (−). The molding of the black diameter or silver diameter is determined by the concentration of silver nitrate contained in the silver liquid.

Since the black diameter or the silver diameter has gloss, which is a property of reflecting light, it is preferable to determine the color according to the color brightness of the intermediate coating layer described later. For example, a black mirror is formed when a dark intermediate coating layer is to be formed, and a silver mirror is formed when a bright intermediate coating layer is to be formed.

Moreover, it is preferable that the thickness of the said coating layer is 20-70 nm.

That is, when the coating layer is less than 20 nm, the flatness of the coating layer may not be maintained as the coating layer is formed in a state recessed in the fine uneven surface formed by the pretreatment process.

In addition, exceeding 70 nm results in the addition of a material cost for forming an excessive thickness, thereby increasing the production cost.

The washing unit 60 removes the incomplete reactants and by-products generated when the black or silver film is formed on the surface of the reflecting plate through the coating unit 50.

That is, the washing unit 60 cleans the surface of the reflecting plate using pure water (H 2 O) as washing water.

The second drying unit 70 removes the remaining water after washing through the washing unit 60.

That is, the second drying unit 70 removes moisture remaining on the surface of the reflecting plate 70 by compressed air obtained through a blower or a compressor. Of course, it is not limited to this, Any means can be used as long as it can remove the water | moisture content remaining on the surface of the reflecting plate 70 easily.

The intermediate coating part 80 forms a intermediate coating layer on the coating layer on which the black diameter or silver diameter coating is formed.

In addition, it is preferable that the intermediate coating liquid of the intermediate coating part 80 is a thermosetting urethane coating. In addition, the intermediate coating liquid is preferably having a variety of colors.

That is, when the black coating film is formed on the reflecting plate 70, the middle coating color of the middle coating part 80 is preferably coated with a dark series, and in the case of the silver coating, the bright coating is preferably included. For this reason, the reflecting plate 70 improves the gloss effect of the coating layer and the color brightness of the intermediate coating layer.

In addition, the intermediate coating layer thickness of the intermediate coating unit 80 is preferably 6 ~ 15㎛.

In some cases, the intermediate coating unit 80 may be omitted.

The top coat part 90 forms a top coat layer as a protective coating on the surface of the reflector plate 70 on which the mid coat layer is formed.

In addition, the top coat portion 90 is preferably any one of a transparent UV paint or urethane paint. Of course, it is not limited to this, Any coating material which can protect the intermediate coating layer or the coating layer formed in the reflecting plate 70 can be used.
