Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color code table for re-coloring wood,

[0001] The present invention relates to a color code table for re-coloring wood and a method for producing the same, and more particularly, to a method for producing a color code for a wood, which can supply a desired color wood product by selecting color and chromaticity And a method for producing a colorless wood using the same.

Wood uses vary. The inherent natural patterns of wood (such as wood grain) can be seen as the greatest strength of wood, which in particular increases the natural sense and aesthetic value. Accordingly, wood is mainly used for building materials such as flooring and wall finishing materials, ornaments, and furniture.

In general, wood products are processed so that the natural pattern of the wood, especially the natural wood grain pattern, can stand out. For example, in the case of plate products, natural veneer sheets are bonded to wood plywood to realize the natural wood grain of the wood. However, this requires a large amount of working water due to the bonding process of the natural veneer sheet and durability is degraded by aging or peeling of the natural veneer sheet.

As another example, in order to stand out the natural wood grain pattern of the wood, the surface of the wood is burnt through the heat treatment using a torch or the like to highlight the grain pattern of the wood itself, and then the wood surface is subjected to brushing, Thereby attaching the grain pattern three-dimensionally. For example, Korean Patent Laid-Open No. 10-2003-0076535 (Prior Art 1) discloses a technique related to this. However, this results in a difference in pattern depending on the degree of carbonization, for example, and there is a problem that the natural feeling is deteriorated due to carbonization.

In order to solve the problems of carbonization as described above, in Korean Patent No. 10-1385434 (Prior Art 2), a surface treatment agent containing soybean oil, sesame oil, cedar liquid, corn oil and charcoal powder is applied and dried, A technique capable of imparting natural feeling and stereoscopic feeling by brushing is proposed.

However, it is difficult to implement various colors in the prior art including the above-mentioned prior art documents. For example, when carbonizing with a torch or the like and applying a surface treatment agent containing charcoal powder as in the prior art document 2 as in the prior art document 1, the color is limited to a black color, It is difficult to do.

Also, as a method of implementing color on wood, there is a method of applying color paint on the surface of wood. However, painting of color paints can achieve various colors depending on the choice of paints, but it drops the natural texture of wood. Above all, the painting of color paints is problematic in that the natural pattern (wood grain pattern, etc.) of the wood is lost due to the lamination of the paint layer, resulting in deterioration of natural feeling and aesthetic value.

On the other hand, consumers and processors of wood products generally have preferred colors. For example, processors such as wooden furniture and ornaments need to supply wood products with the color desired by the consumer (buyer). However, the color of wood is supplied arbitrarily predetermined regardless of the color (color) preferred by a specific consumer or a processing company, and thus the color satisfying degree is not satisfied to the utmost.

At this time, the cup brush 215 installed on the cup-shaped first brush unit 210 first bristles the surface of the wood 100, and is mainly responsible for the etching process. The roll brush 225 installed on the second brush-type brush unit 220 brushes the surface of the wood 100 to form a second brush, which is responsible for uniform etching.

The wood 100 passes through the brushing units 210 and 220 while being carried on the conveying means 110, for example, continuously conveyed in the rightward direction of FIG. At this time, the wood 100 passes by, for example, the brush units 210 and 220 by the conveying means 110 at a speed of 0.1 to 1.0 m / sec. The brush units 210 and 220 are spaced apart from the re-color processor 130 by a distance of 5 to 30 m. At this time, it may be different according to the conveyance speed of the wood 100. However, if the separation distance of the brush units 210 and 220 from the re-color processor 130 is less than 5 m, the penetration time of the hue solution 30 ' (Absorption) amount and / or penetration (absorption) depth (T ₁ ) (T ₂ ) can be lowered. If the separation distance of the brushing units 210 and 220 exceeds 30 m, for example, the process line may be long and may not be preferable in terms of space utilization. In consideration of this point, it is preferable that the brushing units 210 and 220 are spaced apart from the re-coloring processor 130 by a distance of 8 to 20 m.

The distance may also be applied to the dryer 150. Specifically, the dryer 150 described above may be installed between the re-coloring processor 130 and the brushing units 210 and 220 and / or the rear ends of the brushing units 210 and 220. In this case, In the case of being installed between the processor 130 and the brush units 210 and 220, the spacing distance may be applied. That is, when the dryer 150 is installed between the re-coloring processor 130 and the brushing units 210 and 220, the dryer 150 is spaced from the re-coloring processor 130 by 5 to 30 m And may be spaced apart from each other by a distance of preferably 8 to 20 m. The reason is as above. In particular, if the distance between the dryer (150) is too short, the drying time is shortened and the penetration time of the coloring liquid (30 ') is shortened. And if the spacing of the dryer 150 is too long, for example, the process line may be long and undesirable in terms of space utilization.

The spacing distance may refer to the distance from the end (or the center) of the re-coloring processor 130 to the entrance (or center) of the brushing unit 210, 220 or the dryer 150. Further, according to one embodiment, the coloring liquid 30 'can be infiltrated (absorbed) for about 10 seconds to 5 minutes (infiltration time) by controlling the feeding speed of the wood 100 and the spacing distance have.

Meanwhile, according to another embodiment, the manufacturing method of the present invention may further include a sanding process for sanding the surface of the wood 100. The sanding process may be performed using, for example, a sand paper. At this time, the sanding process may be performed before the color remover process and / or after the brushing process. To this end, one or more sanders 120 may be installed at the tip of the re-color processor 130 and / or at the rear end of the brush units 210 and 220. 11 illustrates a state in which one sanding machine 120 is installed at the tip of the re-color processor 130. In FIG. The sanding machine 120 may have a structure in which sandpaper is attached to the surface of a rotating roller, for example.

 The sanding process before the re-coloring step smoothes the surface of the wood 100 (surface homogenization), for example, uniformly applying and penetrating the coloring liquid 30 'during the red coloring step. In addition, the sanding process after the brushing process smoothes the surface of the wood 100, and improves the surface and the beauty of the red-colored wood, for example.

Further, in the present invention, each of the processes is at least one time. That is, the re-coloring step, the brushing step, the drying step and / or the sanding step may be performed only once, or may be repeated several times, if necessary. Further, according to another embodiment of the present invention, the brushing process may be performed before the color re-coloring process. For example, the manufacturing method according to the present invention may sequentially include a brushing process, a colorizing process, and a brushing process.

Hereinafter, the second to fourth embodiments of the method (and apparatus for producing color) of a colorless wood according to the present invention will be described. In describing the second to fourth embodiments of the present invention, terms and reference numerals used in the same manner as in the first embodiment denote the same functions, and a detailed description thereof will be omitted.

At this time, as described in the first embodiment, the grain pattern portion 10 and the ground pattern portion 20 show a difference in penetration depth (T ₁ ) (T ₂ ) due to a difference in inherent property. Specifically, when the coloring liquid 30 'is applied, the grain pattern 10 is hard and has a high density so that the penetration depth T ₁ of the coloring liquid 30' is small and the ground pattern 20 The penetration depth (T ₂ ) of the color liquid 30 'is large because of its smoothness and low density. That is, in Fig. 13B, T ₁ < T ₂ .

The coloring liquid 30 'is infiltrated (absorbed) in the grain pattern portion 10 and the ground pattern portion 20 and the surface of the colorized wood 100 is polished. At this time, in the polishing step, the penetrated portion of the coloring liquid 30 'of the grain pattern portion 10 is etched and removed. 13 (b) and 13 (c), the surface of the grain pattern portion 10 and the ground pattern portion 20 are polished, and the coloring liquid 30 'of the grain pattern portion 10 is polished The penetrated part is etched and removed by polishing.

By this polishing process, the grain pattern portion 10 and the ground pattern portion 20 are etched (sanded) to the same thickness, and the wood 100 has a flat surface. In this case, the penetration depth penetrated by the coloring liquid 30 'of the grain pattern portion 10, that is, the portion indicated by T ₁ in FIG. 13 is etched and removed, but the coloring liquid 30' This penetrated depth of penetration, that is, the portion indicated by T ₂ in FIG. 13, is deep enough to remain at a predetermined depth T ₃ without being completely etched and removed.

According to the third embodiment, a brushing process of first brushing the surface of the wood 100 is carried out. The brushing process may be as long as it allows the hard wood grain pattern 10 to be slightly etched and the soft ground pattern 20 to be relatively etched so as to have a concavo-convex structure on the surface of the wood 100 . That is, the grain pattern 10 may protrude from the ground pattern 20. Specific examples of such a brushing process include those described in the first embodiment. To this end, one or more brushing units 210 and 220 may be provided at the tip of the re-coloring processor 130, and the brushing units 210 and 220 may be disposed at the tip of the re- Same as.

The coloring liquid 30 'is applied on the surface of the brushed wood 100 to penetrate and absorb the coloring liquid 30' from the surface of the wood 100 to a predetermined depth T ₁ (T ₂ ) . At this time, as described in the first embodiment, the grain pattern portion 10 and the ground pattern portion 20 show a difference in penetration depth (T ₁ ) (T ₂ ) due to a difference in inherent property. Specifically, when the coloring liquid 30 'is applied, the grain pattern 10 is hard and has a high density so that the penetration depth T ₁ of the coloring liquid 30' is small and the ground pattern 20 The penetration depth (T ₂ ) of the color liquid 30 'is large because of its smoothness and low density.

 The coloring liquid 30 'is infiltrated (absorbed) in the grain pattern portion 10 and the ground pattern portion 20 and the surface of the colorized wood 100 is polished. At this time, in the polishing step, the penetrated portion of the coloring liquid 30 'of the grain pattern portion 10 is etched and removed. Specifically, the surface of the grain pattern portion 10 and the ground pattern portion 20 are polished, and the portion of the grain pattern portion 10 in which the coloring liquid 30 'is penetrated is etched and removed through polishing. This polishing process is as described in the second embodiment. That is, the polishing process is a process of etching the surface of the wood 100 to a predetermined thickness, which can at least etch away the penetrated portion of the second coloring liquid 30 'of the grain pattern 10 And is not particularly limited.

In the polishing step of the third embodiment, the grain pattern 10 and the ground pattern 20 are etched (sanded) to the same thickness so that the surface irregularity structure is maintained. That is, the portion of the wood grain 10 which is penetrated by the hue 30 'is etched and removed so that the concave-convex structure protruding from the ground pattern 20 is maintained. The portion of the ground tinted portion 20 in which the hue 30 'is penetrated is not deeply etched and removed, but remains at a predetermined depth.

Therefore, the reddish-colored part 30 of the reddish-colored wood according to the third embodiment protrudes from the ground-tinted portion 20 and only the ground tinted portion 20 has a predetermined depth T ₃ . The grain pattern portion 10 has a natural color (natural color) of the wood. In other words, the ground tinted portion 20 realizes color due to the penetration of the coloring liquid 30 ', and the grain pattern portion 10 has a natural color (natural color) ) 20 is prominent and has a three-dimensional effect. At the same time, the grain pattern portion 10 is substantially protruded, and has an excellent three-dimensional embossing feeling.

The brushing process, the red coloring process, and the polishing process may be performed, for example, through the brush units 210 and 220, the color re-coloring processor 130, and the polishing machine 160, respectively. Specific configurations of the brushing units 210 and 220, the color re-coloring processor 130, and the polishing machine 160 are the same as those described in the first and second embodiments.

The wood 100 sequentially passes through the brushing units 210 and 220, the re-coloring processor 130 and the abrasive machine 160 while being carried on the conveying means 110, for example, continuously. At this time, the conveying means 110 conveys the wood 100 at a speed of 0.1 to 1.0 m / sec. The grinding machine 160 is spaced apart from the re-coloring processor 130 by a distance of 5 to 30 m. However, if the separation distance is less than 5 m, the penetration time of the hue solution 30 'may be shortened so that the penetration (absorption) amount and / or the penetration (absorption) depth may be lowered. If the separation distance exceeds 30 m, for example, the process line may be long and may not be preferable in terms of space utilization. In consideration of this point, it is preferable that the abrasive machine 160 is spaced apart from the re-color processor 130 by a distance of 8 to 20 m.

As described above, the dryer 150 may be installed between the re-color processor 130 and the polisher 160 and / or the rear end of the polisher 160.

The reason is as described above. In particular, if the distance between the dryer (150) is too short, the drying time is shortened and the penetration time of the coloring liquid (30 ') is shortened. And if the spacing of the dryer 150 is too long, for example, the process line may be long and undesirable in terms of space utilization.

On the other hand, in the third embodiment, as described in the first embodiment, it is possible to further include a sanding process in which the surface of the wood 100 is sanded and smoothed. The sanding process may be performed using, for example, a sand paper. At this time, the sanding process may be performed before the color remover process and / or after the polishing process. To this end, one or more sanders 120 may be installed at the tip of the re-color processor 130 and / or the rear end of the grinder 160.

The sanding process before the re-coloring step smoothes the surface of the wood 100 (surface homogenization), for example, uniformly applying and penetrating the coloring liquid 30 'during the red coloring step. In addition, the sanding process performed after the polishing process smoothes the surface of the wood 100, for example, can further improve the surface and beauty of the red-colored wood.

The brushing process causes the hard grain pattern 10 to be etched a little and the soft ground pattern 20 to be relatively etched so that the second color liquid 40 ' The penetrated portion may be completely etched and removed, and the first red colored portion 30 formed on the ground tinted portion 20 may be formed so as to be left to a predetermined thickness. This can be implemented, for example, by adjusting the pressing force of the brush units 210 and 220.

As shown in FIG. 15E, after the brushing process, the first re-coloring portion 30, which has been re-colored by the penetration of the first coloring liquid 30 ', is formed in the ground tinted portion 20 to a predetermined depth And the second red colored portion 40 is formed in the grain pattern portion 10 to a predetermined depth by the penetration of the second color liquid 40 '. In addition, a concavo-convex structure is formed on the surface of the wood 100 by the brushing process. 15 (e), the grain pattern portion 10 is etched relatively to the ground pattern portion 20, so that the soft ground pattern portion 20 is etched relatively more than the hard wood pattern portion 10, The surface of the protruding concavo-convex structure (convexo-concave) is formed. Accordingly, the color of the ground tinted portion 20 is realized by the penetration of the first coloring liquid 30 ', and the color of the grain patterned portion 10 is realized by the penetration of the second colored liquid 40' , And the natural patterns (10) and (20) are prominent due to the difference in color upon visual observation, thereby having a three-dimensional effect. At the same time, the grain pattern portion 10 is substantially protruded, and has an excellent three-dimensional embossing feeling.

The first and second re-color processes may be performed through the first and second re-color processors 130, respectively. The polishing process and the brushing process may be performed through the polishing machine 160 and the brushing units 210 and 220, respectively. The specific configurations of the first and second re-color processors 130, the grinder 160, and the brush units 210 and 220 are the same as those described in the first and second embodiments.

The wood 100 is transferred from the first re-color processor 130, the grinder 160, the second re-color processor 130, and the brush unit 210 while being loaded on the transfer means 110, for example, (220). At this time, the conveying means 110 conveys the wood 100 at a speed of 0.1 to 1.0 m / sec. The abrasive machine 160 is spaced apart from the first re-color processor 130 by a distance of 5 to 30 m. The brush units 210 and 220 are spaced apart from the second re-color processor 130 by a distance of 5 to 30 m. The penetration time of the first coloring liquid 30 'and the second coloring liquid 40' is shortened so that the amount of penetration (absorption) and / or the amount of penetration (absorption) of the first coloring liquid 30 ' Or penetration (absorption) depth may be lowered. If the separation distance exceeds 30 m, for example, the process line may be long and may not be preferable in terms of space utilization. The grinding machine 160 and the brushing units 210 and 220 may be spaced apart from the first and second re-coloring processors 130 by a distance of 8 to 20 m, respectively.

As described above, it is preferable that the distance between the first re-color processor 130 and the grinder 160, between the grinder 160 and the second re-color processor 130, between the second re-color processor 130 and the brush unit 210 A dryer 150 may be installed between the first re-color processor 130 and the abrasive machine 160 and / or between the first re-color processor 130 and the abrasive machine 160, and / Or in the case of the dryer 150 installed between the second re-color processor 130 and the brush units 210 and 220, the spacing distance may be applied. That is, when the dryer 150 is installed between the first re-color processor 130 and the grinder 160, and / or between the second re-color processor 130 and the brush units 210 and 220, 150 may be spaced apart from the first and second re-color processors 130 by a distance of 5 to 30 m, preferably spaced apart by a distance of 8 to 20 m. The reason is as described above. Specifically, if the distance between the dryer 150 and the first coloring liquid 30 'is too short, the drying time is shortened and the penetration time of the first coloring liquid 30' and the second coloring liquid 40 'is shortened. And if the spacing of the dryer 150 is too long, for example, the process line may be long and undesirable in terms of space utilization.

On the other hand, in the fourth embodiment, as described in the first embodiment, it is possible to further include a sanding process in which the surface of the wood 100 is sanded and smoothed. The sanding process may be performed using, for example, a sand paper. At this time, the sanding process may be performed before the first colorizing process and / or after the brushing process. To this end, one or more sanders 120 may be installed at the front end of the first re-color processor 130 and / or at the rear end of the brush units 210 and 220.

 The surface of the wood 100 is planarized (surface uniformized) by, for example, uniformly applying and penetrating the first coloring liquid 30 'during the first reding step, . In addition, the sanding process performed after the brushing process smoothes the surface of the wood 100, thereby further improving the surface and beauty of the red-colored wood.

In addition, the manufacturing method according to the fourth embodiment may further include a brushing step optionally performed before the first colorizing step. For example, in the manufacturing method according to the fourth embodiment, the first brushing process-> the first reding process-> the polishing process-> the second reding process-> the second brushing process are sequentially included . At this time, the first brushing step brushes the surface of the wood 100 to make the hard wood grain pattern 10 etched a little and the soft ground pattern 20 a relatively large etched, Any material that can have a concave-convex structure in the wood 100 may be used. That is, the grain pattern 10 may protrude from the ground pattern 20 before the first re-color process. The specific embodiment of the first brushing process includes the portion described in the first embodiment.

According to the present invention described above, an improved coloring wood can be provided. In particular, according to the present invention, as described above, the wood pattern 100 and / or the ground pattern 20 of the wood 100 are colored, and the wood pattern 10 and the ground pattern 20 Have different colors, and the natural patterns 10 and 20 of the wood 100 are prominent and have a three-dimensional appearance. In addition, when the grain pattern 10 protrudes, the natural patterns 10 and 20 become more conspicuous, and the three-dimensional emboss feeling is remarkably improved. In addition, various colors can be implemented in the natural pattern 10 (20). That is, a desired color can be variously implemented according to the selection of the coloring liquids 30 'and 40' on at least one selected from the grain pattern portion 10 and the ground pattern portion 20.
