Abstract

The high-stability fluorescent color paste is prepared from the following main raw materials in parts by weight: 40 to 50 parts of fluorescent pigment, 4 to 6 parts of macromolecular dispersing agent, 0.1 to 1 part of anti-settling agent, 4 to 10 parts of polyalcohol, 1 to 5 parts of micromolecular wetting agent, 0.1 to 0.3 part of preservative and 30 to 50 parts of water. Accroding to the invention, the product has the advantages of good stability, uniform dyeing, high production efficiency, no harm to the environment and human bodies and the like.

Description

technical field [0001] The invention belongs to the technical field of color, and in particular relates to a highly stable fluorescent color paste and a preparation method thereof. Background technique [0002] Fluorescent pigments have the incomparable vividness and brightness of ordinary pigments. Under ordinary light, their brightness is three times that of traditional pigments, and they still have very good effects under low light conditions. Because of the above characteristics, fluorescent pigments can be Widely used in coatings, varnishes, inks, plastics, printing, textiles and other industries to give products bright and bright colors. Existing fluorescent pigments can be divided into powdery pigments and paste pigments according to their state; powdery fluorescent pigments have disadvantages such as weak tinting power, difficulty in dispersing, dust floating into the environment and causing damage to the human respiratory system, while existing Although paste pigme...
