Abstract

A matte solid watercolor pigment is characterized by comprising a dispersant, syrup, dextrin, starch, glue, a bactericidal mildew inhibitor, polyethylene glycol, a filler, toner and a functional aid, the components are uniformly mixed and stirred, and finally matte solid watercolors in different shapes are obtained under the condition that the extrusion temperature of an extruder is 18-25 DEG C. The invention also discloses a preparation method of the matte solid watercolor pigment, which comprises the following steps of stirring, milling, and then extruding and molding. The obtained matte solid watercolor pigment has the advantages of being free of damp, even in pigment diffusion, fine and smooth, free of granular sensation and free of water marks, and meanwhile the preparation method is simple and easy to implement.

Description

technical field [0001] The invention relates to a watercolor paint, and also relates to a preparation method of the paint. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for watercolor painting creation has also been greatly improved. Watercolor painting is created by mixing paint with water to create a unique picture effect, and different watercolor paints have different painting effects. Watercolor paints are divided into matte solid watercolor paints and liquid watercolor paints, and matte solid watercolor paints are a very popular pigment product in the professional and technical field at present. Solid watercolor paints are pure in color in terms of their watercolors, and have a unique color in the painting process. Good transparency and water flow. Compared with liquid watercolor paints and other types of watercolor paints, it has the advantages of high storage stability and portability, so it is widely we...
