Description

Manufacturing method of preserved flower treated with paraline {Manufacturing method of preserved flower treated with parylene}

The present invention relates to a method of manufacturing a preserved flower treated with paralin, more specifically, a preserved flower that can be semi-permanently preserved by applying a sunscreen composition to the preserved flower and depositing paralin. It relates to a manufacturing method and a preserved flower produced thereby.

In general, fresh flowers are harvested from unflowered ecology, and are quickly supplied in an optimal preservation state to minimize moisture evaporation in the distribution stage, but they wither for a week or so and lose their productability. Also, depending on the type of flower, the flowering time and harvest time are different, so it is not easy to appreciate the flowers all year round regardless of the season.

Accordingly, so-called dry flowers made for ornamental use have been produced by natural drying of flowers or artificial drying using a drying agent such as silica gel. However, in this case, there is a problem that the drying time is long and the color or state is not well preserved in the drying process.

Recently, so-called Preserved Flower, which has been able to be stored for a long time through dehydration, decolorization, coloring, drying, and the like, has been distributed. For example, Korean Patent Registration No. 10-1396784 describes an example of a method of manufacturing such a preserved flower. However, even in this case, long-term exposure to natural environments such as ultraviolet light, high temperature, high humidity, and low temperature causes brittleness and discoloration due to the nature of the preserved flower, resulting in poor color clarity. That is, even in the case of such a preserved flower, there is a limit to preserving it semi-permanently.

Accordingly, the present invention provides a preserved flower prepared by the above method.

Hereinafter, the present invention will be described in detail.

The present invention relates to a method of manufacturing a preserved flower treated with paralin, more specifically, a preserved flower that can be semi-permanently preserved by applying a sunscreen composition to the preserved flower and depositing paralin. It relates to a manufacturing method and a preserved flower produced thereby.

In the manufacturing method of the preserved flower according to the present invention, the step of dehydrating and decoloring, coloring, washing, and drying the fresh flowers to be prepared as the preserved flower can be performed by a conventionally known method.

In the first step, fresh flowers to be prepared as preserved flowers may be dehydrated and decolored by immersion in a solution containing C1 to C4 alcohol or a mixed solution thereof. The C1 ~ C4 alcohol may be selected from the group consisting of methanol, ethanol, propanol, isopropanol, butanol and isobutanol. As the C1 to C4 alcohol or a mixed solution thereof, preferably, a mixture of methanol and ethanol in a weight ratio of 5:5 to 8:2 may be used.

The deposition time of the first step is 24 hours to 10 days, preferably 24 to 72 hours, and more preferably 24 to 36 hours. The composition and deposition time of the solution can be appropriately adjusted according to the type or condition of the flower arrangement.

At this time, various ornamental plants such as roses, chrysanthemums, gypsophila flowers, carnations, tulips, and sunflowers can be used as fresh flowers to be produced from the preserved flowers. In addition, if the plant is capable of long-term preservation according to the preparation method of the preserved flower of the present invention, it is not limited to flowers, but also houseplants such as egg, palm, oak, and rubber trees can be used.

In the second step, dehydration and decolorization can be colored by immersion in a solution containing a known natural dye or artificial dye commonly used. The solution is preferably the same as the solution containing the dye in the first step C1 ~ C4 alcohol or a mixed solution thereof. The coloring time is 12 to 72 hours, preferably 24 to 36 hours. By mixing and using various dyes, it is possible to enrich the color to be colored in fresh flowers. At this time, natural dyes are pigments or pigments obtained from natural plants and animals, minerals, etc., for example, gardenia, side, safflower, purple, rock, yellow lotus, rhubarb, yellow wall, quince, yellow and white, joiner, puppet, pomegranate, catechu, glycolysis, It is possible to select and use at least one of a mixture of at least one such as Nurijang tree, chicken coop, flood blood, cloves, acorn, chestnut, walnut, apricot tree, and cinnamon. In addition, artificial dyes are artificially synthesized dyes, and at least one of direct dyes, acid dyes, basic dyes, mordant dyes, emulsifying dyes, naphthol dyes, tendon dyes, oxidation dyes, disperse dyes, fluorescent dyes, etc. It is possible to select and use a mixture by selecting.

In the third step, the colored flowers can be washed with the solution used in the first and second steps. In addition, the solution may include polyols, such as propylene glycol and sorbitol, to give a moisturizing effect to tissues of fresh flowers. The polyols may be mixed in a weight ratio of 1:0.5 to 2 compared to the solutions used in the first and second steps. However, the cleaning time may be 5 to 40 minutes, preferably 5 to 15 minutes. If the cleaning time is too short, the cleaning may not be performed properly. On the contrary, if the cleaning time is too long, it may be discolored, which is undesirable.

In addition, the washed fresh flowers may be dried through natural drying or artificial drying using a dryer. In the case of natural drying, the drying temperature is 10 to 40° C., and the drying time is 1 to 5 days, and preferably 1 to 2 days. In the case of artificial drying using a dryer, the drying temperature is 30 to 70°C, and the drying time may be 12 to 24 hours. The drying time can be appropriately adjusted if it is in a state suitable for applying the composition for sunscreen according to the present invention. If the drying time is too short, the application of the sunscreen composition of the fourth step is not properly applied. On the contrary, if the drying time is too long, there is a fear that the flower may crack or crumble to change shape.

In the fourth step, a composition for blocking ultraviolet rays according to the present invention may be applied to fresh flowers that have undergone the first to third steps. In detail, it is possible to prevent the preserved flower from being discolored by ultraviolet rays by applying the sunscreen composition before the fifth step of depositing the paraline.

The sunscreen composition is characterized in that it contains an extract of yeokpoong, pogongyoung, lotus seeds and cypress leaves. Centella asiatica is a plant with green leaves and stems used for medicinal purposes. Pogongyeong refers to the herbaceous dried dandelion of the Asteraceae family ( Taraxacum platycarpum ). Yeonjayuk is a seed of the lotus of the water lily family ( Nelumbo nucifera Gaertner). And cypress ( Chamaecyparis obtusa ) refers to a plant belonging to the evergreen coniferous tree and belongs to the cypress family that is weak to cold and salt resistance, but resistant to pollution, and the composition according to the present invention may mainly include an extract of cypress leaf.

Preferably, the extract may be 50 to 100 parts by weight of pogongyeong, 50 to 100 parts by weight of soft stalk, and 100 to 200 parts by weight of cypress leaf, based on 100 parts by weight of Centella, extract. If less than 50 parts by weight of the pore pool based on 100 parts by weight of the bottle pool, the sunscreen effect may not appear, and even if it exceeds 100 parts by weight, the sunscreen effect may no longer be increased. If less than 50 parts by weight of soft grass based on 100 parts by weight of bottle grass, the sunscreen effect may not appear, and even if it exceeds 100 parts by weight, the sunscreen effect may no longer be increased. If less than 100 parts by weight of cypress leaf based on 100 parts by weight of Centella, the sunscreen effect may not appear, and even if it exceeds 200 parts by weight, the sunscreen effect may no longer be increased.

In addition, the extract may be extracted using dried cactus, pogongyoung, lotus leaf, and cypress leaves as a solvent of C1 to C4 alcohol or a mixture thereof, and the C1 to C4 alcohol is methanol, ethanol, propanol, isopropanol, butanol and isobutanol It can be selected from the group consisting of. Preferably it may be ethanol.

The C1~C4 alcohol used in the preparation of the extract may use 5 to 20 times the weight based on the weight of the plant mixture in which the herbaceous, pogongyoung, lotus, and cypress leaves are mixed, preferably 10 to 15 times the weight. . The extraction conditions may be 1 to 3 days at 20 to 90°C, and preferably 1 to 2 days. In addition, the above process can be repeated 1 to 4 times.

The extract may be used as it is by extracting a mixture of a plant mixture and a solvent, or it may be concentrated and used. The content of solids in the extract may be 1-20 mg/g. When an extract of less than 1mg/g is used, the sunscreen effect may not appear, and even if an extract of more than 20mg/g is used, the sunscreen effect may not be increased any more.

The sunscreen composition of the present invention, if necessary, known water repellents, oil repellents, fluorescent agents, drying rate modifiers, crosslinking agents, membrane preparation aids, compatibilizers, surfactants, antifreeze agents, viscosity modifiers, antioxidants, pH adjusters, Anti-foaming agents, anti-slip agents, antistatic agents, hydrophilic agents, antibacterial agents, preservatives, insect repellents, fragrances, flame retardants, and the like.

The method of applying the composition for sunscreen according to the present invention may use a spray method, a deposition method, a painting method, a plasma treatment method, etc., and preferably may be a spray method. The amount of the sunscreen composition applied to the preserved flower by the above method is preferably 0.1 to 20 g/m ² , more preferably 0.5 to 10 g/m ² . Application may be performed once, but may be carried out in multiple circuits.

In the fifth step of depositing the paraline, the paraline may be coated through chemical vapor deposition (CVD), for example, a paraline dimer is inserted into the evaporator in a powder form 120 ~ It is evaporated in the gas phase at 180℃. The evaporated dimer is converted into monomers through a pyrolysis furnace heated to 650 to 700°C. The thermally decomposed monomer collides with the surface of the preserved flower in the deposition chamber and undergoes a polymer polymerization reaction to form a thin film of paralin on the surface of the preserved flower. The paraline dimer used at this time may be one selected from the group consisting of paraline-C, paraline-N, and paraline-D of the following Chemical Formulas 1 to 3, and preferably, paraline-C is used.

In addition, when depositing a thin film of paralin, the composition pressure is 5 to 20 mTorr, and the deposition rate is preferably 1.0 to 2.0 μm/hr. If the composition pressure and the deposition rate are less than the above range, the parline thin film is not sufficiently coated, and if it exceeds, the parlin thin film may aggregate. However, the method of coating the thin film of paralin on the surface of the preserved flower is not limited thereto.

The present invention relates to a method of preparing a preserved flower treated with paralin and a preserved flower produced thereby. Preserved flowers prepared through the present invention, even when exposed to natural environments such as ultraviolet light, high temperature, high humidity, low temperature, have a unique color and shape for at least 3 years or more, preferably compared to the preserved flower prepared by the existing method. Since it can be maintained for more than 5 years, it is very effective in commercializing for ornamental purposes. In addition, even after the treatment with paralin as described above, it can be stored in a transparent sealed container or the like as needed to minimize the exposure to the external environment for a longer period of time.
