Abstract

PROBLEM TO BE SOLVED: To easily produce a plant product such as a flower or a leaf enabling the appreciation of natural shape and color for a long time in a mass scale by substituting the water in the plant with an organic solvent, then optionally applying a resin on it and thereafter evaporating the organic solvent. SOLUTION: The shape and the color of a plant are fixed by immersing the plant in a volatile organic solvent without damaging the shape even in a soft plant owing to the buoyant force of the liquids or by spraying or coating the organic solvent on a plant to substitute the water in the plant with the solvent and to harden the plant. Subsequently, the solvent is evaporated. Further, a resin is optionally applied on the plant whose inside water has been substituted with an organic solvent and the solvent is evaporated after the resin impregnates into cells. Furthermore, a resin-impregnated plant is coated with a nitrile rubber- modified resin and dried. This can prevent the collapse of a plant attributable to its brittleness. This method requires less expensive installation cost and the product is obtained in a short time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for allowing ornamentation or observation for a long period of time by retaining the shape and pigment of plants, especially ornamental flowers and leaves, for a long period of time.

[0002]

2. Description of the Related Art Conventionally, there is a dry flower method for holding plants. This method evaporates water by drying. Therefore, the shape contracted and was different from the natural body. However, as another method of forming dried flowers in a natural shape, it was possible to make a shape close to a natural body by immersing the plant in a desiccant such as silk gel and drying. Further, as another method, there is a freeze-drying method in which the shape and pigment are retained by freezing the plant and raising the water content in a vacuum. Further, there is a method in which an aqueous resin such as glycerin is sucked up from the root of the plant and replaced with water of cells of the plant to maintain the shape.

[0003]

However, these conventional methods have some problems. One is that when it is buried in a desiccant such as silica gel, it takes a lot of work and time to fill the desiccant to the edges of the flower due to the complicated flower shape and the softness of the petals. 2 at room temperature
It takes one day to three days. Even after drying, the plants are fragile when taken out from the desiccant, so they are easily damaged. Further, the powder of the desiccant adheres to the surface of the petals, and it takes time and labor to remove them. On the other hand, in the freeze-drying method, since it takes a long time of 7 to 10 days to dry the raw plants and remove water, there is a problem that mass production is affected. Also, absorb hygroscopic agents such as glycerin from the root of the plant.
Regarding the method of maintaining the shape, in a hot and humid climate such as Japan, the hygroscopicity of the drug causes it to flow out from the inside of the plant to the extent of shrinkage. In addition, there is a problem that the natural color of the pigment is discolored or faded.

Here, organic solvents (alcohols, polyhydric alcohols and their derivatives, petroleum-based hydrocarbons, ethers, acetals, ketones, esters) are useful for retaining plant shapes and pigments. Of the plant shape by making it easy to work, drying it in a short time, and impregnating it with a resin (melamine urea resin, melamine resin, 2-liquid ester epoxy resin, acrylic resin, 2-liquid urethane resin) The inventors have completed the invention of a method of holding a dye and a pigment for a long period of time and preventing fragile plants from being damaged by a nitrile rubber-modified resin.

[0005]

[Means for Solving the Problems] That is, the present invention relates to a plant in which volatile organic solvents (alcohols, polyhydric alcohols and derivatives thereof, petroleum-based hydrocarbons, ethers, acetals, ketones, esters) are used. By immersing it in a liquid, it does not lose its shape even if it is a soft plant using its liquid buoyancy, or an organic solvent (alcohols, polyhydric alcohol and its derivatives, petroleum-based hydrocarbons,
Water and organic solvents (alcohols, polyhydric alcohols and their derivatives), petroleum-based hydrocarbons, ethers inside the plant by spraying and applying ethers, acetals, ketones, esters) to plants , Acetals, ketones, esters) to harden the plant and fix its shape and pigment. And the dried plant will lose its shape by evaporating the substituted organic solvents (alcohols, polyhydric alcohols and their derivatives, petroleum-based hydrocarbons, ethers, acetals, ketones, esters). It is dried without retaining the dye. The time required for these steps is from 1 hour 30 minutes to 2 hours, and the time required depends on the water content in the plant. In addition, there is no residue on the surface of plants because organic solvents (alcohols, polyhydric alcohols and their derivatives, petroleum-based coal hydrocarbons, ethers, acetals, ketones, esters) are volatilized. .

[0006] First, the water content of the plant cells is replaced with a water-soluble organic solvent (alcohols, polyhydric alcohols and their derivatives, ethers, acetals) to harden the plants, and then the plant surface has a texture. In order to obtain smoothness or to adjust the density of the pigment, the solvent of petroleum-based coal-based hydrocarbons and esters is impregnated and adjusted.

[0007] However, the water-removed and dried plant immediately absorbs water in the air and becomes soft and loses its shape, and the pigment quickly fades due to the water. The present invention dilutes a melamine urea resin, a melamine resin, a two-component ester-based epoxy resin, an acrylic resin, and a two-component urethane resin with a solvent in order to prevent the softening of plants due to the moisture in the air. Resin, melamine resin,
In order to infiltrate the two-part ester epoxy resin, acrylic resin, and two-part urethane resin into the plant body, organic solvents (alcohols, polyhydric alcohols and their derivatives, petroleum-based hydrocarbons, ethers, The resin is applied to and penetrated into plants impregnated with acetals, ketones, and esters. Then, the resin that has permeated by drying is hardened to prevent softening due to moisture in the air for a long time.

Further, the permeated and hardened resin (melamine urea resin, melamine resin, two-component ester type epoxy resin, acrylic resin, two-component urethane resin) is shaped so as to cover around the plant pigment. This is a method of suppressing fading by blocking moisture in the air to some extent.

However, even if the plant is impregnated with a resin (melamine urea resin, melamine resin, two-component ester epoxy resin, acrylic resin, two-component urethane resin) and dried, the plant is still fragile. A nitrile rubber-modified resin (synthetic rubber resin) diluted with a solvent is applied to the tough coating to prevent the fragile plants from being damaged.

[00010]

[Function] In addition to water in plants, water-soluble organic solvents (alcohols, polyhydric alcohols and their derivatives, ethers,
Substitute with acetals by dipping or spraying, then other organic solvents (petroleum-based hydrocarbons, ketones,
(Esters). And the substituted organic solvents (alcohols, polyhydric alcohols and their derivatives, petroleum-based hydrocarbons, ethers, acetals, ketones, esters) harden the cells and do not shrink even when evaporated. . Also, since cells and pigments in the plant are easily dissolved in lower alcohol (methanol) and flow out to the outside, a combination of large molecular weight ethanol and isopropyl alcohol or ethanol and other organic solvents (petroleum-based hydrocarbons,
Use of an organic solvent in combination with ethers, acetals, ketones, esters) prevents outflow during dipping or spraying. When the dehydration of flowers and stems is completed, the surface of the plant is finely smoothed by impregnating or dipping it with a solvent of petroleum-based coal-based hydrocarbons or esters by dipping or spraying. Then, the organic solvent (alcohols, polyhydric alcohols and their derivatives, petroleum-based coal hydrocarbons, ethers, acetals, ketones, esters) is impregnated into the plant body by heating or the organic solvent (alcohol). , Polyhydric alcohols and their derivatives, petroleum-based hydrocarbons, ethers, acetals, ketones,
The time can be shortened by exposing it to the vapor of the ester. As a result, the equipment cost is lower and production is quicker and easier than the conventional dry flower method or freeze-dried flower method using silica gel.

However, hot-air-dried or heat-dried plants absorb moisture (moisture) in the air and soon become soft and lose their shape or discolor pigments. Therefore, when the plant contains organic solvents (alcohols, polyhydric alcohols and their derivatives, petroleum-based hydrocarbons, ethers, acetals, ketones, esters), the resin (melamine urea) Resin, melamine resin, two-component ester-based epoxy resin, acrylic resin, two-component urethane resin) diluted with a solvent (so as to have a nonvolatile content of 10 to 15%) is applied, and these resins are intracellularly applied. Impregnate (in addition,
It is difficult to impregnate dried plants), and by drying this, these resins harden,
Prevents plants from softening due to moisture and prevents fading of pigments.

However, even if the resin (melamine urea resin, melamine resin, two-component ester epoxy resin, acrylic resin, two-component urethane resin) is impregnated into the cells and cured, the dried plants are fragile. A nitrile rubber modified resin with a strong coating film is applied to the surface of the plant to prevent damage to the fragile plant.

[00013]

EFFECTS OF THE INVENTION According to the production method of the present invention, the natural shape and color of ornamental flowers and leaves among plants can be enjoyed for a long time (about 4 to 6 months). It can be mass-produced more easily than the above method.

[00014]

[Example] A flower whose stem is cut short is placed in a tank containing an organic solvent (isopropyl alcohol: ethanol = 2: 1) and immersed. After about 10 to 15 minutes, the water in the flower and the stem is dehydrated, and the buoyancy in the liquid causes the shape to be natural and hard. For further dehydration (if water remains, it shrinks as much, so water must be removed as much as possible), soak for about 1 to 1.5 hours. After that, the organic solvent in the tank (isopropyl alcohol: ethanol =
2: 1) is taken out, the flower is impregnated with an organic solvent (isopropyl alcohol: ethanol = 2: 1), and the melamine resin diluted with xylol is applied by dipping or spraying with an air gun. Then, it is dried with warm air (to allow the resin to penetrate into the plant). Next, the dried flower is coated with a diluted nitrile rubber-modified resin and dried.

Hanging leaves and flowers with stems, first spray ethanol with airless spray or air gun spray, and when application, flowers and leaves become hard due to dehydration, then use isopropyl alcohol in the same manner. It is applied for 2 to 3 seconds, and is left standing for 30 seconds to 40 seconds for about 1.5 hours.
After applying for 2 hours, apply melamine resin (diluted),
A nitrile rubber-modified resin is diluted with xylol on flowers, stems, and leaves that have been dried with warm air and then dried, and this is applied and dried by spraying or dipping with an air gun or an airless gun.
