DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a transparent resin-coated dry flower in which the surface of a petal of a three-dimensional dry flower is hardened thinly.

[0002]

2. Description of the Related Art In a dry manic state in which a flower is embedded in a non-breathable transparent resin, its color changes and it can be stored for a long time in a very beautiful state. To realize this, the following methods have been proposed, and these techniques are described in the following publications.

JP-A-7-25703 JP-A-2-184602

[0004] In the official gazette of the publication, a dried plant is turned upside down inside a case, and a liquid transparent resin which is a 24-hour curing type epoxy resin for mixing and curing two liquids is injected and cured. The method of embedding with is described in the patent gazette.

[0005] Japanese Patent Application Publication No. 2000-139,056 discloses a method for preventing fading of pressed flowers in which a coating layer of an ultraviolet curable resin is provided on the entire surface of the pressed flowers stuck with an adhesive on a tile.

[0006]

The method of embedding an epoxy resin which mixes and cures two liquids can be embedded in the resin. However, in the case of a dry flower that requires a thin film for the petals, if a 24-hour curing type epoxy resin is used to mix and cure the two liquids, the heat radiation surface area is large and the reaction heat is not accumulated, making it difficult to cure. . In the case of the type that cures in a short time, the flower changes color due to the heat of reaction. When an organic amine is used as the curing agent, the discoloration of the flower occurs in a short period of time due to the organic amine after curing. When an acid anhydride is used as a curing agent, the surface area of contact with the air is significantly larger than that of embedding, so that moisture in the air may be absorbed to generate free acids and discolor flowers. It is very difficult to perform a hardening operation without discoloration of the dried flower that requires a thin film.

A method for preventing fading of a pressed flower in which an ultraviolet curable resin coating layer is provided on the entire surface of the pressed flower is a method of curing a pressed flower in a flat state, and can cure the pressed flower. However, there has been no study on a method of irradiating ultraviolet rays and a method of manufacturing a three-dimensional dry flower having a gap between petals, and the shape and color of the flower pattern are maintained, and the inclination of the flower and the flower pattern can be freely adjusted during decoration. No consideration has been given to ways that can be changed. Also, no study has been made on a manufacturing method using electron beam irradiation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has the beauty of the shape of a three-dimensional dried flower and the preservation of color for a long period of time. It is another object of the present invention to provide a method for producing a resin-coated interior article having a short length. The present invention also provides a method for producing a transparent resin-coated dry flower that can be freely bent while maintaining a floral pattern and color.

[0009]

Means for Solving the Problems In order to achieve the above object, the invention according to claim 1 is a method for applying a transparent ultraviolet curable resin liquid to a three-dimensional dry flower holding the shape of a fresh flower. After removing the excess resin liquid, it is a method of curing the petals evenly by irradiating ultraviolet rays from all directions,
The ultraviolet curable resin liquid is a transparent resin monomer or prepolymer containing an ultraviolet sensitizer, or a mixture thereof. When irradiated with ultraviolet rays, the sensitizer generates active radicals, and the resin liquid undergoes a polymerization reaction to be cured. The method of applying the ultraviolet curable resin liquid includes a method of dipping a dry flower in the ultraviolet curable resin liquid and a method of applying the ultraviolet curable resin liquid to the dry flower. The extra resin liquid is the amount of resin unnecessary for forming a three-dimensional dry flower coating. In order to remove the excess resin liquid, there are a method of allowing the resin to fall naturally, and a method of causing the resin to fall by applying a slight vibration. This is because a large force is not applied to the dried flower and the brittle dried flower is not damaged.

According to a second aspect of the present invention, a dry flower from which the excess resin liquid has been removed is disposed in an apparatus provided with at least one ultraviolet light source and a reflection plate over the entire periphery, and is cured by irradiating ultraviolet rays. 2. The manufacturing method according to claim 1, wherein a mirror, a metal plate or a metal foil, a metal deposition film, a metallic coating, or the like is used as the reflection plate. In order to arrange the dried flowers in the device provided with the reflection plate, there are a hanging method, a method of fixing a floral pattern, and the like. An ultraviolet fluorescent lamp or a high-pressure mercury lamp can be used as the ultraviolet light source. Even if one or more UV light sources are used, they can be radiated from all directions by the reflector on the entire surface and do not create shadows of petals, and can be cured to every corner, but use multiple UV light sources By doing so, curing can be performed in a shorter time.

The invention according to claim 3 is characterized in that a dry flower is made after inserting an optical fiber into the lower part of a petal from a flower pattern and sepals of a fresh flower. In the method, most of the fresh flowers insert optical fibers into the floral pattern when the flowers are fresh because the center of the floral pattern is hollow or spongy or soft. A flower having a wooden pattern at the center of a flower of a tree is dried after being inserted from a sepal, and is hardened in a short time through an optical fiber at the time of irradiation with ultraviolet rays according to claim 1 or 2. Can be.

[0012] The invention according to claim 4 is the method according to claim 1 or 2, wherein a dry flower is made after inserting a metal wire from a flower pattern of a fresh flower into a lower part of a petal. Inserting the metal wire from the flower pattern of the fresh flower to the lower part of the petal is easy because the center of the flower pattern of the flower and many tree flowers is hollow or spongy or soft, and the metal wire is easy to insert, This is because the flour is brittle and the transparent resin-coated dry flour becomes dense, making insertion difficult.

[0013] The invention according to claim 5 is to apply a transparent electron beam-curable resin liquid to a dry flower, and then apply a slight vibration to remove excess resin liquid in a short time, and then irradiate the electron beam for a short time. Method to obtain a transparent resin-coated dry flower,
The electron beam-curable resin liquid is a monomer or a prepolymer or a mixture thereof. Unsaturated polyester resin, acrylic resin, alkyd resin and the like can be used for the electron beam curing resin liquid. The electron beam is generated and irradiated by an electron beam accelerator. Active radicals are generated in the molecules of the resin liquid by irradiation with the electron beam and polymerized. The electron beam can penetrate through the thin petals and cure to every corner in a short time.
