Description

Preparation method and application of plant pigment for interior painting

Technical Field

The invention relates to a preparation method and application of a plant pigment for interior painting, belonging to the technical field of interior painting pigment research.

Background technique

After cigarettes became popular, snuff fell out of fashion. Craftsmen used their ingenuity and skills to shape transparent materials such as glass, agate, and crystal into pots. After hollowing out the cavity, they added small steel balls, quartz sand, and a small amount of water into the pots and shook them back and forth, grinding the smooth inner wall into a fine surface so that the pigment and ink could easily adhere. Then, bamboo, copper, and aluminum with curved hooks were used as materials, which were cut and ground into needle-like fineness and curved like the moon. Wolf and sheep hair were tied to make brushes. Based on the painting techniques, ink was used to reverse the painting with colors, which gradually became the amazing art of snuff bottle inner painting that has been passed down to this day.

Traditional inner painting pigments are generally directly selected from Chinese painting pigments and oil painting pigments; there is also the use of ceramic pigments for baked inner painting. These traditional inner painting pigments have low corrosion resistance and are not easy to preserve for a long time, which is a major technical bottleneck of inner painting techniques.

Summary of the invention

The object of the present invention is to provide a method for preparing a plant pigment for interior painting, which specifically comprises the following steps:

(1) Wash, dry, and mash fresh petals for later use.

(2) Add alum, apigenin or oxymatrine, and propylene to the crushed fresh petals, mix well, seal, and place for 25 to 30 days. For 100 g of crushed fresh petals, the amount of alum added is 8 to 12 g, the amount of apigenin or oxymatrine added is 10 to 15 g, and the amount of propylene added is 40 to 50 ml.

(3) The mixture obtained in step (2) is ground again and sealed for later use.

Preferably, the fresh petals of the present invention are fresh petals with antibacterial properties.

Preferably, the fresh petals of the present invention are petals of red roses, and the obtained plant pigment is red.

Preferably, the fresh petals of the present invention are petals of yellow roses, and the obtained plant pigment is yellow.

Preferably, the fresh petals of the present invention are lavender petals, and the obtained plant pigment is blue.

The present invention can also select other petals to prepare plant pigments, with red, yellow and blue being basic colors, which can be used in combination to obtain different colors.

The plant pigment of the present invention is mixed with one or more of gold powder, silver powder and tin powder and added to acrylic for coloring, and the amount of each pigment added is adjusted according to actual needs. The addition of gold powder, silver powder and tin powder can make the color more textured. For example, adding gold powder and silver powder to draw some mines, stones, etc. can make the picture sparkle, more realistic and three-dimensional.

Beneficial Effects of the Invention

(1) The plant pigment prepared by the method of the present invention uses fresh flower petals as raw materials and can be used alone as raw materials for painting flower petals. The colors are very bright and lifelike, and the colors are stable and will not fade. The prepared plant pigment can be stored in the air for a long time without discoloration. As the use time increases, the pigment changes from a paste to a block, and can return to the original color after adding some acrylic acid. It is very convenient to use and store.

(2) The reason why the plant pigment prepared by the method of the present invention can be stored in the air for a long time without fading may be that the fresh petals themselves have antibacterial properties, and at the same time react with alum to produce new preservative substances, and apigenin or oxymatrine has the effect of stabilizing the color.

(3) The plant pigment of the present invention is easy to use and can be combined with mineral raw materials, tin powder, and gold powder to produce different colors. Compared with conventional Chinese painting pigments and oil painting pigments, the pigment of the present invention has the advantages of strong corrosion resistance, large color changes, and good environmental performance. In terms of color, the color is more beautiful and bright, and very beautiful.

Detailed ways

The present invention is further described in detail below in conjunction with specific embodiments, but the protection scope of the present invention is not limited to the described contents.

Example

A method for preparing a plant pigment for interior painting, specifically comprising the following steps:

(1) Wash, dry, and crush fresh red rose petals for later use.

(2) Add alum, apigenin and propylene to the crushed fresh red rose petals, mix well, seal and place for 25 days. For 100 g of crushed fresh petals, the amount of alum added is 10 g, the amount of apigenin added is 15 g and the amount of propylene added is 45 ml.

(3) The mixture obtained in step (2) is ground again and sealed for later use.

Example

A method for preparing a plant pigment for interior painting, specifically comprising the following steps:

(1) Wash, dry, and crush fresh yellow rose petals for later use.

(2) Add alum, oxymatrine and propylene to the crushed fresh yellow rose petals, mix well, seal and place for 28 days. For 100 g of crushed fresh petals, the amount of alum added is 12 g, the amount of oxymatrine added is 10 g and the amount of propylene added is 50 ml.

(3) The mixture obtained in step (2) is ground again and sealed for later use.

Example

A method for preparing a plant pigment for interior painting, specifically comprising the following steps:

(1) Wash, dry, and crush fresh lavender petals for later use.

(2) Add alum, oxymatrine and propylene to the crushed fresh lavender petals, mix well, seal and place for 30 days. For 100 g of crushed fresh petals, the amount of alum added is 8 g, the amount of oxymatrine added is 13 g and the amount of propylene added is 40 ml.

(3) The mixture obtained in step (2) is ground again and sealed for later use.

Comparative Example 1

The conditions of this embodiment are the same as those of embodiment 1, except that apigenin or oxymatrine is not added.

Comparative Example 2

The conditions of the present embodiment are the same as those of Example 1, except that no alum is added.

Both Examples 1 and 3 can obtain plant pigments, Example 1 obtains a red pigment, Example 2 obtains a yellow pigment, and Example 3 obtains a blue pigment, and the pigments are all very bright and can be stored in the air for a long time without changing color for 2 to 3 years.

The plant pigment described in the embodiment of the present invention can be used in combination with gold powder, silver powder, and tin powder for color adjustment during use. For example, camellia can be mixed with red plant pigment plus tin powder and acrylic, and the color of the mine can be mixed with yellow pigment, gold powder, and silver powder. After adding gold powder, silver powder or tin powder, the texture of the picture will be better.

The corrosion resistance, fluidity, uniformity, color difference and antibacterial property of the pigments obtained in Examples 1 to 3 were tested by conventional methods. The corrosion resistance test method was as follows: the inner painting drawn with the pigment was placed in salt spray and the color change was observed. The experimental results are shown in Table 1.

Table 1

It can be seen from Table 1 that the pigments prepared in Examples 1 to 3 have good uniformity, antibacterial properties, corrosion resistance and stability, and the addition of alum and matrine is beneficial to improving the performance of the pigments.
