Problems solved by technology

Although the pigment slurry in the prior art uses water as the diluent, which is environmentally friendly and hygienic, and is easy to adjust, there are still the following problems: after using acrylic paint for painting, the acrylic paint forms a layer of paint film on the surface of the paper, but due to the acrylic paint Water-soluble properties, when encountering a high humidity environment, the paint film is easy to moisture-proof and soften, and will fade, and the painting will last for a short time

Abstract

The invention discloses a moisture-regain-resistant drawing pigment in the technical field of pigments. The pigment is prepared from the following raw material components in parts by weight: 50-60 parts of acrylic emulsion, 5-10 parts of diatomite, 5-10 parts of talcum powder, 8-12 parts of toner, 5-10 parts of vegetable gum, 5-8 parts of thickener, 5-8 parts of humectant, 0.3-0.5 part of dispersing agent, 3-8 parts of film-forming agent, 0.03-0.06 part of preservative and 10-15 parts of water. The moisture-regain-resistant drawing pigment of the invention can absorb moisture in the air, so that the moisture regain resistance of the pigment is improved, and the fading time of the pigment is prolonged.

Description
