The invention relates to a solid water-powder stick which is prepared from the following components in percentage by weight:

10 to 20 percent of stearic acid;

7% -16% of glycerol;

0.1% -0.6% of polydimethylsiloxane;

MIT 0.1％-0.2％；

0.1 to 5 percent of pigment;

the balance being water.

Further, in the solid gouache stick, the pigment is any one of a blue pigment, a light blue pigment, a purple pigment, a green pigment, a white pigment, a black pigment, a red pigment, a pink pigment, an orange pigment, a yellow pigment, a light green pigment and a brown pigment.

The invention relates to a preparation method of a solid water-powder stick, which comprises the following steps: weighing the components according to the weight ratio, adding stearic acid, glycerol, polydimethylsiloxane, MIT and pigment into water, heating and stirring until the mixture is in a molten state, filling into a mold, and cooling and forming to obtain the solid gouache stick.

Further, the temperature of the mixture in a molten state is 60 to 80 ℃.

In the composition for manufacturing the solid gouache stick, stearic acid and polydimethylsiloxane have a smoothing effect on a final product, stearic acid has a softening and softening effect on the final product (the solid gouache stick), and polydimethylsiloxane has a lubricating effect on the final product (the solid gouache stick); stearic acid and polydimethylsiloxane act together to give the final product (solid water stick) a smooth character.

The glycerin has a plasticizing effect on the polydimethylsiloxane in the formula, and the glycerin and the polydimethylsiloxane jointly act to enable the final product (solid gouache stick) to have quick-drying characteristics, which is probably because the polydimethylsiloxane can permeate into the substrate under the modification of the glycerin, so that the substrate is easy to dry quickly on the surface and moisturizes the inside of the substrate.

And because of the permeability and moisture retention of the polydimethylsiloxane, the glycerol, the polydimethylsiloxane and the stearic acid enable the final product to have the characteristics of strong adhesion and compatibility of various painting materials.

Since each component is a water-soluble component, the final product (solid water powder stick) has the property of being water-soluble, and thus is easy to clean with water.

MIT is a bactericidal preservative that can make the final product sterile and prevent decay, ensuring the end product's life.
