Description

The present invention relates to a method for producing a flower that changes color depending on temperature and light intensity.

The present invention relates to a flower that changes color, and currently, flowers having various patterns and colors have been developed for each type. In particular, roses are called the Queen of Flowers, among which a variety of species have been developed and the market value is quite high. A lot of forms, patterns and fragrances have been developed in addition to the color of flowers, but there are few cases where one kind of flower has all colors, for example, roses and carnations are not purple to blue varieties, and are buds and dragons There is no bright red variety.
Roses that did not have yellow varieties have been developed as yellow roses that are commercially available through mating, but there are limits to the color of flowers that can be achieved by breeding by mating, where the available genetic resources are limited.
Although it can be said that there is a blue rose at present, its color is lighter purple than blue, and several more advanced forms of blue rose have been developed, but such flowers are also completely blue It is hard to say.
Conventionally, there have been methods of adding colors to flowers using dyes in addition to making flowers of a desired color through mating. This is to use the capillarity of plants. If fresh flowers are prepared, warm water of about 40 ° C. and a promotion liquid are mixed with each color liquid and left for about 30 minutes to 2 hours. The water rose up into the capillaries and reached the leaves, changing the color of the flowers to the desired color.
However, this method simply changed the color of the flower and resulted in shortening the flower life by allowing the flower to absorb chemicals.
In addition, to change the color of the flower, the thermochromic pigment and the photochromic pigment are directly colored on the petals. However, the thermochromic pigment and the photochromic pigment are not easily colored on the petals. In many cases, the thicker the pigment layer, the more difficult it is to dry the pigment and the more the pigment layer is not colored.

The present invention provides a method for processing a flower that does not affect the life of a flower while not only applying to a desired color by overcoming the disadvantages described above, but also changing color due to external conditions such as temperature and sunlight. With the goal.

In order to achieve the above object, a method for producing a flower that changes color, comprising:
30 to 60 parts by weight of oil paint with respect to the total weight;
A step of producing a mixture by mixing 20 to 40 parts by weight of any one or more pigments selected from a temperature pigment and a light pigment;
Spraying the mixture directly into the petals in a sprayer;
Drying the sprayed flowers of the mixture in the shade;
Can be included.
The method may further include mixing at least one selected from thinner and lacquer with 30 to 40 parts by weight of the mixture based on the total weight.
The nozzle of the sprayer may be 0.1 mm to 1.0 mm.
The step of drying the flowers may be within 30 minutes.

According to the above-described invention, not only the petal is applied to a desired color, but also the effect of producing various flowers by changing the petal color depending on the light amount and temperature.

In order to achieve the above-described effects, the present invention provides a method for producing a flower that changes color due to temperature and sunlight.
1 shows a method for processing flowers according to the present invention.

In the present invention, paint and dye are applied to the petals using a sprayer. At this time, the paint used is an oil paint.
In the case of water-based paint, the petals may become moldy and rot due to moisture remaining after coloring.
In addition, since the enamel paint has a slow setting speed even in the case of oil paint, paint that contains a thinner or rocker component and vaporizes quickly is used.
A dye is mixed and applied to the paint. At this time, a light-indicating dye containing a light-indicating pigment or a temperature-indicating dye containing a temperature-indicating pigment is used.
The light-indicating pigment (PLASOL PHOTOCHROMIC COLORS) is a pigment that changes its color by sunlight or ultraviolet rays. When exposed to ultraviolet rays, the color appears, and when the ultraviolet rays are blocked, the hue disappears. Such photopigments have various solvent properties, and can be used with toluene, xylene, methyl ethyl ketone, ethyl acetate, etc., and other color effects can be obtained by combining the photopigments. It is possible to produce other colors by mixing the light-indicating pigment and the general pigment, and it is possible to express other colors by mixing the light-indicating pigment and the general pigment.
A temperature indicating pigment refers to a pigment whose hue changes with temperature. When the temperature increases, the color gradually disappears, and when the temperature decreases, the original color returns. For example, in the case of a blue thermochromic pigment that changes color at 20 ° C., it appears blue at 20 ° C. or less, but the color disappears at 22 ° C. In the case of an orange thermochromic pigment that changes color at 31 ° C., the hue disappears completely at 35 ° C. when heat at 31 ° C. is applied. Since such a pigment is a pigment that varies depending on human body temperature, it is applied to products that vary depending on body temperature. Such temperature indicating pigments and light indicating pigments can obtain other effects by combining two or more pigments and combining other colors.
Thus, the mixture which combined the oil-based paint, the display pigment, the temperature pigment, etc. is apply | coated to a petal like a rose. At this time, a thinner that is not paint may be mixed separately in order to increase volatility.
In this case, it is preferable that 30 to 60 parts by weight of the oil-based lacquer series paint to be mixed is mixed with 30 to 40 parts by weight of the total amount of the oil-based thinner. It is preferable that the mixture of other temperature pigments and light pigments is contained in an amount of 20 to 40 parts by weight based on the total weight.
In the case of 7 cc of the mixture thus mixed, about 70 can be applied by applying using a nozzle having a diameter of 0.2 mm. A nozzle having a smaller diameter may be used, and since it is applied by a spray method using a sprayer, it is applied in a thin layer as much as possible while having a desired color, and within a short time. The volatile components are volatilized and applied.
The diameter of the nozzle is suitably 1.0 mm to 0, 1 mm. If the thickness is 1.0 mm or more, there is a possibility that the droplets of the mixture become large and the drying process and the thickness of the coating layer may be problematic. The resulting mixture volatilizes and is not sufficiently applied.
When applying to the petals, rather than applying to the whole petals, after coloring a part of the petals (about 30%), and drying in the shade for about 30 minutes, all the volatile components are volatilized. Only the light pigment and paint should remain on the petals. The conventional method cannot be applied to a part of the flower.
Conventionally, petals often rot before or after being colored with water-based paint, and there is a problem that they are not colored because volatile substances are not mixed. After application, it can be applied only by drying in the shade.
According to the above method, it is possible to express almost all hues such as red, orange, yellow, green, blue, indigo, and purple depending on the type and color of the paint and pigment used. It is possible to change the color to purple when exposed to light. In particular, when applied only to the end of the petal, the color of the petal varies depending on the amount of light.
When using a blue thermochromic pigment whose color disappears at 25 ° C. for red paint, it turns red at 25 ° C. or higher, but becomes deep purple at 15 ° C. or lower. If you look at the degree of change from a low temperature, the color will change to dark purple-purple-pink-red as the temperature rises.
A yellow thermochromic pigment that changes color at 31 ° C. is used for the blue paint, and the color is green below 20 ° C., but as the temperature rises, only the blue paint remains at about 31 ° C. while yellow disappears. When a change from a low temperature is observed, the color changes in the order of green, light green, sky blue, and blue.
In addition, since this method is simply applied to petals, it can be applied not only to fresh flowers but also to express a free hue without affecting the life of flowers. Conventionally, the method of allowing a petal to absorb a dye has a disadvantage in that the lifetime is shortened compared to a general rose because a flower absorbs a chemical dye.
It is also possible to change the color depending on the temperature and light quantity by mixing the indicator pigment and the indicator pigment together, and by changing the temperature by changing the indicator pigment together, Manufacturing is possible. Therefore, not only the difference in temperature between day and night, but also the life of the flower is not affected, so it is possible to produce a flower that changes color depending on the season.
