Abstract

The invention relates to a preparation method of high color fastness water-based acrylate resin color paste, resin color paste and its application and use method. The water-based acrylate resin color paste is a core-shell structure polymer, and the core polymer is acrylate The composition of polymer and pigment, the shell polymer is a water-based acrylate polymer synthesized by emulsion polymerization. In the present invention, by adding pigments during the reaction process, the molecular chains and pigments in the polymer solution synthesized by solution polymerization are more uniformly dispersed and combined more closely, and the pigments are evenly dispersed and wrapped in the latex particles after the polymer self-emulsifies to form latex particles. It reduces the uneven dispersion of pigments and the phase separation caused by aggregation during the film-forming process of the slurry, and greatly improves the color fastness of the water-based acrylic resin colorant.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a water-based acrylate resin color paste with high color fastness, a preparation method and its use as a coating composition and a coating and using method. Background technique [0002] The color paste is a coating paste that disperses various types of pigments into the textile adhesive, and the pigments are fully mixed evenly, so that the resin has a certain coloring power and hiding power. In the textile industry, the color paste is coated on the base fabric, and after drying to form a film, the pigment is fixed on the surface of the fabric fiber by the adhesive, which not only makes the fabric present a variety of colors, but also gives the fabric fastness, wear resistance, and hand feeling. and other quality improvements. With the development of social economy and people's pursuit of a higher quality of life, the application of color paste is becoming more and...
