Pure natural soybean crayon and preparation method thereof
Technical Field
The invention relates to the technical field of crayon production, in particular to a purely natural soybean crayon and a preparation method thereof.
Background
The crayon is made up by mixing pigment in wax, and can be used for drawing pictures with tens of colours. The crayon has no permeability, is fixed on a picture by adhesive force, is not suitable for being made of too smooth paper and board, and cannot obtain the composite color by repeated superposition of colors. But the crayon can also achieve the artistic effects of rich and bright color and thick pigmentation through the contrast of hue between light or thick coating and color. In addition, the crayon can be directly shaped by freely mastering the thick and thin strokes, so that a highly generalized artistic image is generated, and the crayon has special clumsy aesthetic feeling. It is an ideal tool for children to learn color and painting, and some paintings are used for painting from life and color recording. Under the condition of careful protection, the freshness and the preservation time of the color crayon are longer than those of oil painting or water color painting. They do not fade as oil painting does nor get damp as watercolor painting does. The beauty of the colored crayon is mainly characterized by the soft velvet-like surface, which endows the painting with color harmony depth and atmosphere which cannot be achieved by other methods. Color crayons are particularly useful for drawing portraits, still images, and certain landscapes.
Along with the continuous development of art education industry, people are to the demand of fine arts drawing, and more art supplies trend market, because infant's education demand also has more and more art supplies to need the safety guarantee.

table 1 is a table of test data for examples 1-11 with an inserted natural soy crayon
From the data, we can see that the pure natural soybean crayon provided by the invention has better structural stability, wherein the dehydrated soybean dregs have main structural effects, the integral stability of the crayon can be further improved by matching with vegetable powder, and the vegetable powder can be complementary with edible natural pigment, so that the color rendering degree of the crayon is improved. The beeswax and the rice oil have certain viscosity and serve as main adhesives of the crayon, so that the effect of adhering the dehydrated soybean dregs and the vegetable powder into a whole is achieved, if purified water is added, the structural stability of the crayon is reduced, the fracture resistance is greatly reduced, and the coloring function is lost. Meanwhile, the proportion of the dehydrated soybean dregs to the beeswax and the rice oil is moderate, and the addition of the beeswax and the rice oil is too small, so that the adhesiveness of the crayon is insufficient, the dehydrated soybean dregs are easy to fall off, and the folding resistance and the coloring effect are influenced.
The present invention has been described in detail with reference to the embodiments, and it should be noted that the specific features described in the above embodiments may be modified in combination by any suitable means without contradiction, and the present invention will not be described in any way. Further, other modifications and combinations of the features of the invention, as well as other variations and combinations of the features of the invention, are also contemplated as being within the scope of the invention.
