Abstract

<P>PROBLEM TO BE SOLVED: To provide a grain-patterned structural material giving a feel of an woody atmosphere. <P>SOLUTION: A grain-patterned coating film 1 is formed on the surface of a structural material A, and a protective coating film 2 is formed on the upper surface of the grain-patterned film 1. The grain-patterned film 1 is formed by scratching a coating film in a half-dried state after coating with a brush-like implement to draw a large number of streaks. The grain-patterned structural material is produced by applying a coating to the surface of the structural material A, scratching the coating in a half-dried state with a brush-like implement, applying a protective coating on the upper surface of the resultant product and drying. Since the grain pattern on the surface of the structural material makes the structural material appear like a woody material, a warm atmosphere characteristic of woody materials can be produced. Since the grain pattern is retained well by the protective coating, the woody atmosphere can be kept over a long period. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a structural material with a wood grain pattern. Metal materials such as steel and aluminum, resin, wood plywood, and the like are used as structural materials such as columns, beams, and frames. The present invention relates to such structural materials.

  The metal material as the structural material is usually used as it is in the ground color or is usually painted in a single color (Non-Patent Document 1). Therefore, it is suitable for producing the functional beauty of metal, but it cannot produce the warmth of wood. Therefore, the architectural design can only be the same design as the metal products that are commonly used.

  In addition, if the resin material is only painted in a single color, it just feels inorganic. Furthermore, even if it is a woody material, in the case of plywood, the grain has disappeared, so it is not possible to experience the sense that exists with the nature created by the grain pattern.

  However, even with the above metal materials, resin materials, plywood, etc., if you can feel the naturalness of the wood grain and produce the warmth like wood, designs with changes will be possible, including buildings This is advantageous because the design of the structure is improved.

  In view of the above circumstances, an object of the present invention is to provide a structural material with a wood grain pattern that can feel a woody atmosphere. It is another object of the present invention to provide a wood grain pattern painting method and painting apparatus.

The structural material with a wood grain pattern according to the first invention is characterized in that a wood grain pattern coating film is formed on the surface of the structural material, and a protective coating film is formed on the upper surface thereof.
The structural material with a wood grain pattern of the second invention is characterized in that the wood grain pattern coating film is obtained by scraping with a brush-like material in a semi-dry state of the painted coating film and attaching a plurality of lines. To do.
The method of painting a wood grain pattern on the structural material of the third invention is to apply a paint to the surface of the structural material, scrape with a brush-like material in a semi-dry state, apply a protective coating on the upper surface, and dry the paint. Features.
According to a fourth aspect of the present invention, there is provided a grain pattern coating apparatus comprising a table for holding a structural material and a moving mechanism for moving a brush-like object along the structural material on the table.

According to the first aspect of the invention, the wood grain pattern formed on the surface of the structural material makes the structural material appear as if it is a wooden material, so that a warm atmosphere of the wooden material can be produced. Moreover, since the wood grain pattern is held by the protective paint, the atmosphere of the wood material can be felt for a long time.
According to the second invention, since the coating film has an appropriate viscosity when it is in a semi-dry state, many fine lines are clearly attached when scraped with a brush-like material. Moreover, since this line has a design similar to a natural grain, the degree of completion as a grain pattern increases.
According to the third aspect of the present invention, when the paint applied to the surface of the structural material is scraped off with a brush-like material in a semi-dry viscosity state, the traces become a large number of lines and become a natural grain pattern. Next, when the protective coating is applied and dried, the wood grain pattern is fixed, so a high quality wood grain pattern can be easily formed.
According to the fourth aspect of the invention, the structural material is held by the table and the brush-like object is moved by the moving mechanism, so that the wood grain pattern can be efficiently painted.

Next, an embodiment of the present invention will be described with reference to the drawings.
1A is a perspective view of a structural material according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view.
Although the structural material A in FIG. 1 is columnar, the structural material to which the present invention is applied is not limited to such a shape, and can be applied to any shape. As a material of the structural material, it can be applied to a metal material such as aluminum or stainless steel, a resin material, or a plywood having lost grain.
In the figure, the wood grain coating film 1 is applied only to one surface of the structural material A, but it may be formed on two or three surfaces, or on the entire surface.

The wood grain pattern coating film 1 looks like a wood grain pattern by a large number of streaks attached to the general coating film formed on the surface of the structural material A. As the paint for forming this general coating film, any kind of paint can be used without particular limitation. A protective coating film 2 is formed on the surface of the wood grain pattern 1.
It is preferable to form the base coating film 3 on the lower surface of the wood grain coating film 1 (that is, the direct surface of the structural material A). When the base coating film 3 is formed, when the wood grain pattern coating film 1 is scraped off, it is possible to form a grain composed of two different patterns, the base coating film 3 and the wood grain pattern coating film 1. And there exists an advantage that a color tone can be increased infinitely by changing the color of the ground coating film 3 and the wood grain pattern coating film 1 mutually. Moreover, when the protective coating film 2 is formed, there exists an advantage that the wood grain pattern coating film 1 is protected and a weather resistance increases.

Next, the coating method of the present invention will be described with reference to FIG.
(1) As a pretreatment of the structural material A, oil or the like is removed (101).
(2) Base coating is performed by hand or electrodeposition (102).
This undercoating is not essential and may be omitted depending on the material and use of the structural material. Reference numeral 3 shown in FIG. 1B is a base coating film formed by this base coating.
(3) Apply general paint (103).
The coating method can be any method such as hand-painting, air gun, or dob pickling.
There are no particular restrictions on the type of coating material, and any type of coating material may be used, as long as a suitable viscosity appears in a semi-dry state. Reference numeral 2 shown in FIG. 1B is a coating film formed by this general coating, and streaks described later are formed in this coating film.

(4) The paint film is scraped off with a brush-like material (104).
This step is performed in a state where the coating film coated in (3) is semi-dry.
The semi-dry state refers to a state where the coating film has a viscosity that allows a large number of streaks to adhere to the coating film when scraped with a brush. When fluidity is high at the start of painting, the paint will flow later and the streaks will disappear even if you sweep with a brush. Moreover, when the curing progresses after a long time after the application is finished, even if the brush is swept away, the streaks are not attached. Therefore, the streaks after sweeping with a brush must not disappear and must be scraped off with a brush in a semi-dry state meaning that the streaks are attached, that is, with a moderate viscosity.

The brush used for scraping the paint film is most suitable for general paint. The hardness of the brush hand is soft and hard, but it is only necessary to have a streak on the paint film. How hard the brush is used depends on the type of paint and the size of the streak of the wood grain pattern you want to attach. What is necessary is just to select suitably. Moreover, even if it is a thing other than the brush used for painting, if a streak can be attached to a coating film, it can be used for this invention. For example, a brush, a scrubbing brush, a brush, and a metal object having a saw-tooth can be exemplified as such a thing. In the present specification, such a thing other than the brush is referred to as a brush-like object.
When a sticky paint film is scraped off with a brush-like material, a large number of fine lines are clearly attached, and the lines are designed to have a pattern close to natural grain, so the degree of completion as a grain pattern increases. .

(5) Apply protective coating (105).
In this step, a protective coating is applied on the lines of the wood grain coating film 1 formed in (4). In addition to transparent clear coating, colored coating may be used for this protective coating.
Since the protective coating film 2 formed in this way retains the wood grain pattern, it can produce an atmosphere of wood material over a long period of time.
(6) Dry (106).
All coatings are fixed by drying after applying general and protective coatings.
When this drying process is finished, the wood grain pattern is fixed, so a high quality wood grain pattern can be easily formed.

  According to the above coating method, the wood grain pattern on the surface of the structural material A shows the metal resistance A as if it were a natural woody material, so that a warm atmosphere of the woody material can be produced.

Next, a specific method for forming a wood grain pattern will be described.
The method shown in FIG. 3 is a method of scraping the coating film 1 by holding the brush 10 by hand. In this method, it is possible to give a wood grain pattern of any design by freely changing the degree of pushing of the brush 10 and the degree of blurring to the left and right.

FIG. 4 shows a screw rod type coating apparatus according to the first embodiment.
Reference numeral 11 denotes a screw rod which is driven to rotate by a motor 12. A slider 13 having a nut is attached to the screw rod 11, and the brush 10 is held by the slider 13. The structural material A is placed on the table 15.
When the general coating is applied on the structural material A, the pressing force of the brush 10 is appropriately adjusted, and the slider 13 is moved, the wood grain pattern coating film 1 with a large number of streaks can be formed on the coating film. .

FIG. 5 shows a Narai type coating apparatus according to the second embodiment.
The table 15, slider 13, and brush 10 are the same as in FIG. Reference numeral 21 denotes a narai cam that guides the left and right movement of the slider 13, and the slider 13 is urged by a tension spring 23 so as to always contact the narai cam 21. Reference numeral 22 denotes a narai cam that guides the vertical movement of the slider 13, and the ladder 13 always abuts against the narai cam 22 by its own weight. The slider 13 is moved manually or by an appropriate push-pull mechanism.
When this apparatus is used, since a change in the horizontal direction can be given to the streaks on the coating film, or the depth of the groove of the streaks can be varied, a more natural woodgrain coating film 1 can be applied. .

FIG. 6 shows a numerical control type coating apparatus according to the third embodiment.
The table 15, slider 13, and brush 10 are substantially the same as in FIG. Moreover, although the moving mechanism in the longitudinal direction is a screw rod type consisting of a screw rod 11 and a motor 12, it is not limited to this.
In addition, a screw rod 31 and a motor 32 constituting the left and right fine movement mechanisms 30 and a screw rod 41 and a motor 42 constituting the upper and lower fine movement mechanisms 40 are provided. Each of these motors 12, 32, 42 rotates in the direction and amount controlled by the numerical controller. For this reason, since the brush 10 can be changed in the left-right direction, or the depth of the groove of the muscle can be varied, a more natural woodgrain coating film 1 can be applied.

  According to each of the above-described apparatuses, the formation of the wood grain pattern can be automated, so that efficient work can be performed.
