Description

Technical Field

[0001] The invention relates to the technical field of flower color changing, and in particular to a flower color changing composition and a preparation method and a spray thereof. Background Art

[0002] Flowers are so attractive because of their bright colors, but ordinary flowers can only bloom in one color. If you want to change the color of fresh flowers, the usual method is that the flowers absorb dyes (sterile water dissolves various pigments) through the flower stems to make the flowers meet the color changes required by a certain color, thereby achieving color beautification.

[0003] If ordinary flowers are dyed into colorful colors, certain professional knowledge is required, which increases the price of flowers and takes a long time to dye. In today's fast-paced life, the waiting time cost increases. With the improvement of people's living standards and the individual needs of artistic life, if ordinary flowers can be changed to change color at any time and DIY at will, it will undoubtedly meet market demand. Aerosols are widely used because of their convenient construction and simple operation. Using aerosol technology, combined with the characteristics of aerosol products and design requirements, a flower color-changing spray has been developed, which can realize DIY flowers at any time. Once sprayed, the flowers will not be damaged or faded. The colors are natural and diverse, which instantly improves the appearance of flowers, and the cost is low.

[0004] Yang Rong, Fan Shumiao, Lu Yuanxue and others published a paper titled "Study on the Dyeing Technology of Rose Everlasting Flowers with Lithospermum Plant Dye" in Western Forestry Science. The paper mixed lithospermum powder with ethanol solution to prepare lithospermum dye solution, which was then freeze-dried to obtain natural lithospermum plant dye powder. The dehydrated and decolorized rose everlasting flowers were then placed in the natural lithospermum dye solution and sealed with a sealing film for dyeing. At the same time, the authors conducted single-factor experiments on the concentration, temperature, pH value, and dyeing time of the dye and analyzed the effects of the above factors on the dyeing effect.

[0005] This document has conducted a single factor experiment on the dyeing conditions (dye concentration, dyeing time, dyeing temperature, pH) of natural comfrey dye, preliminarily screened out the appropriate experimental level, and then optimized its dyeing conditions through orthogonal experiments. When dyeing for 7 hours, the dye concentration is 0.2%, the temperature is 40°C, and the pH value is 3, the dyeing performance of the dyed rose is better. However, it should be noted that although the scheme does not specify which process of suction dyeing and spray dyeing is used, combined with the above methods, at least the dyeing technology used in this document is not spray dyeing technology, and the requirements for dyes for spray dyeing and washing dyeing technology are also different to a certain extent. Therefore, the dye disclosed in this scheme may not be able to be used in spray dyeing technology.

[0006] Chinese patent application 202110707447.2 discloses a method for sucking and dyeing fresh cut peony flowers, comprising the following steps: selection of flower materials, selection of ripeness, selection of dyes, selection of containers, selection of fresh cut peony flowers, and a method for sucking and dyeing fresh cut peony flowers of different ripeness; this scheme selects food additive grade pigment dyes, and during the sucking and dyeing process, the coloring is uniform, and the mixed colors can be freely blended and blended. In the later period of the vase period, the phenomenon of petals wilting is only three to five percent, and the effect has reached the conditions for commercial application. In terms of market application, it fills the market gap of dyed fresh cut peony flowers; the sucking and dyed fresh cut peony flowers are packaged in a box for 24 hours through a normal cold chain or air transport route, and the vase test is carried out after taking out, which shows that they can open normally and the coloring is stable; at the same time, it can be seen that this scheme also uses the sucking and dyeing process to dye fresh flowers.

[0007] Chinese patent application 200980140237.7 discloses a composition for dyeing plant petals, a dyeing method thereof, and a plant having petals dyed thereby. In this scheme, the composition for functional dyeing of plant petals is as follows: 10 to 100 grams of functional pigments are mixed with every 1 to 2 liters of a dissolved substance selected from ethanol and acetone, and the functional pigments contain 5 to 20 grams of one or more of oil-soluble dyes, komari crystal color pigments, primer pigments, temperature-indicating pigments, and light-indicating pigments selected from general pigments other than edible pigments. For every 100 weight of the solution mixed with the oil-soluble dye, the functional pigment, and the dissolved substance, one or more adhesives selected from polyvinyl acetate solution, enamel, or polyurethane resin adhesives are further mixed at a ratio of 10 to 20.

[0008] At the same time, the scheme also discloses a method for functional dyeing of plant petals, including:

[0009] Material preparation stage, preparing materials for dyeing;

[0010] In the dyeing liquid manufacturing stage, the prepared materials are mixed to manufacture the dyeing liquid;

[0011] During the dyeing liquid spraying stage, the manufactured dyeing liquid is placed in a barrel with a water pump or air pump installed inside, and the water pump or air pump is started to provide 50kg / m 2 The air pressure is about 100%, and the petals are sprayed with the sprayer; and the dyeing liquid is dried in the drying stage,

[0012] Among them, the dyeing liquid manufacturing stage is: 10 to 100 grams of functional pigments are mixed with every 1 to 2 liters of dissolved substances selected from ethanol and acetone, and the functional pigments contain 5 to 20 grams of one or more of oil-soluble dyes, komari crystal color pigments, primer pigments, temperature-indicating pigments, and light-indicating pigments selected from general pigments other than edible pigments, and one or more adhesives selected from polyvinyl acetate solution, enamel or polyurethane resin adhesives are further mixed at a ratio of 10 to 20 for every 100 weight of the solution mixed with the oil-soluble dye, the functional pigment and the dissolved substances.

[0013] From the above method, the flower dyeing method adopted in the scheme is spray dyeing, and the dye used in the scheme is at least one of oil-soluble dyes, komari crystal color pigments, primer pigments, temperature-indicating pigments, and light-indicating pigments other than food coloring, and it is dissolved in an organic solvent such as ethanol or acetone. In addition, the ethanol and acetone in which the pigment or dye is dissolved need to be mixed with one or more adhesives selected from polyvinyl acetate solution, enamel or polyurethane resin adhesives to obtain a dye;

[0014] This solution uses the above-mentioned dyeing method and composition to apply luminous or phosphorescent treatment to the original color of flowers, thereby providing a new aesthetic feeling and an opportunity to appreciate them even in the dark, thereby further increasing the added value of the product. The petals are not easy to wither and can be preserved for a long time. Anyone can dye the petals easily and quickly anytime and anywhere without being restricted by conditions and environment, or maintain the original color of the flowers for luminous or phosphorescent dyeing treatment. However, this solution does not conduct too many tests on the coloring time of the flowers and the retention time of the color after dyeing.

However, it should be noted that although the above-mentioned coating is more suitable for spraying the exterior wall of a building, flowers have higher requirements on the particle size, raw materials and other components of the spray relative to the exterior wall of a building.

[0097] Performance Testing:

[0098] Viscosity test: Tu-4 cup viscosity test, designed according to GB / T 1723-93, is suitable for measuring the viscosity of coatings (flow time is not more than 150 seconds); under certain temperature conditions, it measures the time for a quantitative sample to flow out of a hole of a specified diameter, expressed in S;

[0099] Specifically in this application, the temperature during the test is 25°C. It should be noted that the shorter the outflow time, the lower the viscosity, and the longer the outflow time, the higher the viscosity;

[0100] Drying time test: the flower color-changing composition prepared in the embodiment and the comparative example is put into an aerosol sealed can, a stirring bead is put in, and the universal valve and the aerosol sealed can are sealed with a sealing machine; then dimethyl ether is poured in, and a pressing head is installed to prepare a flower color-changing spray, wherein the mass ratio of the flower color-changing composition to dimethyl ether is 2:1;

[0101] Then, the flower color-changing spray was sprayed onto the surface of the rose, and the drying time of each embodiment and comparative example was measured. The specific results are shown in Table 7:

[0102] Table 7

[0103]

[0104] Result analysis:

[0105] Combination Figure 1-10 And Table 1 for the results analysis, we can find that:

[0106] 1. It can be seen from Examples 1-4 that when the addition amount of each raw material in the formula is controllably adjusted, there is a certain difference in viscosity and drying time between Examples 1-4, but the difference is not obvious; however, in actual use, since the alcohol-soluble acrylic resin in Examples 2 and 3 is added twice, the particle size of the titanium dioxide during the sanding process is more uniform, so that after the composition is used to change the color of the flowers, the coating on the surface of the flowers presents a more delicate visual effect.

[0107] 2. It can be seen from Examples 1 and 5-9 that when the alcohol-soluble propylene resin and the leveling agent in the formula are compounded separately, the viscosity of the obtained flower color-changing composition is not much different from that of Example 1, but it can be seen that the drying time has an obvious downward trend. After the alcohol-soluble propylene resin and the leveling agent are compounded separately, the flower color-changing composition is easier to dry. We believe that the reason for this phenomenon is that the glass transition temperatures of different alcohol-soluble propylene resins are different, which leads to the difference in drying time between multiple compositions;

[0108] Simultaneous observation Figure 1-3 It can be seen that the uniformity of Example 5 and Example 7 is improved relative to that of Example 1, indicating that compounding the alcohol-soluble acrylic resin and the leveling agent respectively can improve the uniformity of distribution of the color-changing agent prepared later on the surface of the flower to a certain extent;

[0109] At the same time, it can be seen from Examples 8-9 that after further compounding the alcohol-soluble propylene resin, leveling agent, and defoaming agent, the drying time is further shortened. Figure 4-5 It can be seen that the distribution uniformity of the color-changing agent on the surface of the flowers is further improved. We believe that the reason for this phenomenon is the synergistic effect of compounding the alcohol-soluble acrylic resin, leveling agent and defoaming agent.

[0110] 3. It can be seen from Example 1 and Comparative Examples 1-2 that when other commonly used resins in the art are used instead of the resin used in Example 1, although the viscosity and drying time of the flower color-changing composition do not change significantly, the observed Figure 6-7 It can be seen that the uniformity of the distribution of the color-changing agent prepared subsequently on the surface of the flowers is significantly reduced, which further proves that improving the uniformity of the distribution of the color-changing agent on the surface of the flowers is the result of the combined effect of the resin and the leveling agent;

[0111] 4. It can be seen from Example 1 and Comparative Examples 3-4 that when the amount of ethanol added in the formula is reduced or increased, the viscosity and drying time of the flower color-changing composition change significantly. Figure 8-9 It can be seen that after the color-changing agent prepared from the composition obtained in Comparative Examples 3 and 4 is sprayed on the surface of the flower, its uniformity is significantly reduced; therefore, we believe that the uniformity of the color-changing agent on the surface of the flower is not only affected by the resin and the leveling agent, but also by the drying time and viscosity caused by the selection of the solvent and the change in the addition amount. Figure 8 More intuitive, Figure 8 The left side is a color-changing agent obtained from the composition prepared in Example 1. Figure 8 The right side shows the color-changing agent made from the composition prepared in Comparative Example 3. It can be seen that the uniformity of the color-changing agent made from the composition prepared in Comparative Example 3 on the surface of the flower is significantly lower than that in Example 1.
