Abstract

The invention belongs to the technical field of color fixing agents, and particularly relates to a color fixing agent for artificial colored sand, a preparation method of the color fixing agent and the artificial colored sand. The color fixing agent is prepared from 20 to 40 parts of nano acrylic emulsion, 10 to 20 parts of waterborne polyurethane, 20 to 40 parts of anionic-cationic silicone acrylic emulsion, 30 to 40 parts of nano silicon, 15 to 50 parts of organic silicon waterproof agent, 1 to 5 parts of alkaline substance, 1 to 10 parts of quick drying agent and 1 to 5 parts of anti-aging agent. The preparation method of the color fixing agent comprises the following steps: mixing the nano acrylic emulsion, the waterborne polyurethane, the anionic-cationic silicone acrylic emulsion, the nano silicon, the organosilicon waterproofing agent and the anti-aging agent, then adding the alkaline substance, uniformly stirring, and finally adding the quick-drying agent to prepare the color fixing agent for the artificial colored sand. When being applied to a coating for artificial colored sand, the pigment can effectively improve the coloring effect of a dye coating on the surface of the colored sand, so that the colored sand coating is not easy to fade.

Description

technical field

[0001] The invention belongs to the technical field of color-fixing agents, and particularly relates to a color-fixing agent for artificial colored sand, a preparation method of the color-fixing agent, and artificial colored sand. Background technique

[0002] Natural colored sand is pulverized from natural ore. It does not fade but has many impurity colors, few colors and limited production. It is mainly used in building decoration, terrazzo aggregate, real stone paint, colored sand paint, etc. In recent years, due to the development of the construction industry, the market demand for colored sand is increasing, and the limited colored sand can no longer meet the market demand.

[0003] The existing artificial colored sand is prepared by coating the sand with a coating containing pigments. Compared with the natural colored sand, the artificial colored sand has a complete range of colors, good color stability between batches, and easy adjustment. The color i...
