DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
[0019]
“First Embodiment”
A first embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 designates a chopstick substrate 1, and in the present embodiment, a chopstick substrate 1 made of a natural material (such as reddish malus) such as wood or bamboo is employed.
[0020]
Therefore, the method of applying the chopsticks according to this embodiment will be described below. First, as shown in FIG. 1, the release plate A is stretched and fixed to the stretcher G, and an uncured coating P is uniformly applied to the upper surface of the release plate A to a required width and is decorated. A film 20 is formed. At this time, it is easy to apply the coating P uniformly on the upper surface of the release plate A by roller coating.
[0021]
Further, the release plate A employs a release liner made of nylon in which the surface of the plastic film is subjected to a release treatment with a silicon resin, so that the decorative coating film 20 can be easily peeled off.
[0022]
In addition, as the coating material P in the present embodiment, an epoxy resin whose viscosity is adjusted by mixing a curing agent such as polyamide at about 100: 80 is used. In this case, a synthetic resin such as an acrylic resin, a polystyrene resin, a polyurethane resin, or a melamine resin may be mixed with a curing agent.
[0023]
Then, the makeup target portion of the chopstick substrate 1 is brought into horizontal contact with the decorative coating film 20, and the chopstick substrate 1 is rolled along the longitudinal direction of the release plate A. Then, the decorative coating film 20 is peeled off from the release plate A, and is transferred onto the surface of the makeup target portion of the chopstick base 1 and can be wound up.
[0024]
At this time, the adhesiveness of the decorative coating film 20 can be improved by previously applying a primer to the entire surface of the chopstick substrate 1. Normally, only an epoxy resin is used for this primer, but in this embodiment, a better adhesive effect can be obtained by mixing with a polyurethane resin.
[0025]
Next, as shown in FIG. 2, the base end portion 11 of the chopstick substrate 1 is erected in the insertion hole opened on the upper surface of the support J. Then, the decorative coating film 20 is dried and cured while the support tool J is reversed alternately upside down depending on how the decorative coating film 20 hangs down.
[0026]
The inversion time for equalizing the degree of sag immediately after adhesion of the decorative coating 20 is shown below.
Elapsed time Number of inversions 0 minutes to 5 minutes 4 times per minute 5 minutes to 10 minutes 2 times per minute 10 minutes to 20 minutes 1 time per minute 20 minutes to 45 minutes 1 time per 5 minutes 45 minutes to 60 minutes 7 Once per minute 60 minutes to 90 minutes Once per 10 minutes 90 minutes to 120 minutes Once per 20 minutes 120 minutes to 240 minutes Once per 30 minutes [0027]
In this embodiment, after the drooping ends as described above, the decorative coating film 20 is prevented from foaming by being naturally dried for about 8 hours and forcibly dried at 70 ° C. for about 4 hours while adjusting the drying temperature. Thus, when the decorative coating film 20 is cured, a thick decorative layer 2 can be formed on the peripheral surface of the chopstick substrate 1 (see FIG. 3).
[0028]
In the present embodiment, after the decoration layer 2 is formed, the pattern decoration 21 can be applied to the surface of the decoration layer 2 by screen printing or gravure printing. Further, the protective layer 3 can be formed by covering the surface of the decoration layer 2 thus provided with the pattern decoration 21 with a transparent resin (for example, epoxy resin) (see FIG. 4).
[0029]
Therefore, in the present embodiment, the chopstick substrate 1 is rolled by using the fact that the bonding performance of the surface of the chopstick substrate 1 is stronger than the bonding force between the decorative coating film 20 and the release plate A. The decorative coating 20 can be transferred onto the surface and wound up.
[0030]
Further, once the decorative coating 20 having a uniform width is formed on the release plate A, it is possible to prevent uneven coating as in the case where the paint P is directly applied to the surface of the chopstick substrate 1, and necessary. The decorative layer 2 having a large thickness was formed to express a heavy appearance.
[0031]
“Second Embodiment”
Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, a coating material P is prepared by mixing a decorative material into a transparent adhesive synthetic resin (in this embodiment, an epoxy resin mixed with a polyamide curing agent), and the uncured coating material P thus prepared is prepared. Is applied to the upper surface of the release plate A to a required width and a uniform thickness to form a decorative coating film 20.
[0032]
Then, as in the first embodiment, this decorative coating film 20 is transferred from the release plate A to the surface of the makeup target portion of the chopstick substrate 1 and wound, and the decorative coating film 20 is dried and cured to thereby decorate the decorative layer. 2 is formed.
[0033]
Incidentally, gold powder is used for the decoration material of the present embodiment, and a three-dimensional pattern can be formed by the gold powder appearing on the surface through the transparent decoration layer 2. In addition, as a decorative material, plastic powder, pigments, natural leaves, rice grains, shells, and the like can be employed.
[0034]
“Third Embodiment”
A third embodiment of the present invention will be described with reference to FIG. In the present embodiment, a through-hole T is previously opened in the makeup target portion of the chopstick substrate 1, and the through-hole T is filled with a transparent resin (for example, acrylic resin).
[0035]
Then, in the same manner as in the above embodiment, by winding the transparent decorative coating film 20 so as to cover the hole, the other side of the chopstick substrate 1 can be seen through the transparent resin of the through hole T portion. The decorative layer 2 can be formed.
[0036]
In the first to third embodiments, as shown in FIG. 7, the base end portion 11 of the chopstick substrate 1 is cut, and the cut surface is coated with a paint P and dried and hardened, whereby a decorative ceiling portion is obtained. It is also possible to form 23.
[0037]
Further, the surface of the decorative layer 2 can be chopped to form the decorative engraving 22, and then the chopstick substrate 1 can be coated with a paint such as lacquer to be finished.
[0038]
The embodiments specifically shown in this specification and the drawings are generally as described above. However, the technical scope of the present invention is not limited to the embodiments described above, and is within the scope of the claims. Numerous design changes are possible.
[0039]
For example, the makeup target portion of the chopstick substrate 1 is not limited to one, and a plurality of portions may be provided. After winding the decorative coating on the release plate A around the surface of the chopstick substrate 1, the release plate A of the chopstick substrate 1 The decorative coating film 20 can be wound up by changing the position of contact with the film.
[0040]
Further, as shown in FIG. 8, after the plurality of decorative layers 2 and 2 are formed, the protective layer 3 may be covered by integrating them and attaching a transparent resin. Furthermore, if necessary, the thickness of the decorative layer 2 to be formed later can be adjusted to be easy to hold by cutting and forming the peripheral surface to be a makeup target site in advance.
[0041]
Furthermore, by mixing a material having a high specific gravity with the coating material P and forming the decorative layer 2 on the base end portion 11 side of the chopstick substrate 1, the center of gravity can be easily moved and can be easily used. Furthermore, it is also possible to add grip properties by mixing the anti-slip material into the paint P to form the decorative layer 2 or coating the surface with anti-slip. Belongs to a range.
[0042]
【The invention's effect】
As described above with reference to the embodiment, according to the coated chopsticks makeup method of the present invention, the adhesive performance of the surface of the chopstick base is skillfully utilized that is stronger than the bonding force between the decorative coating and the release plate. By rolling the chopstick substrate, the decorative coating film can be rolled up on the surface and wound, and once the uniform coating film of uniform width is formed on the release plate, It is possible to prevent uneven coating as in the case where a paint is applied to the surface of the substrate and to form a decorative layer having a necessary thickness to express a heavy appearance.
[0043]
In this way, although it is a simple process, it can be applied to the surface of the chopsticks substrate uniformly and thickly to give a heavy coating decoration, and a uniform product can be made, so it is very rational It is suitable for mass production and has a very high practical value in chopsticks decoration technology.
