Abstract

The invention relates to a preparation method of high-color-fastness water-based acrylate resin color paste, the resin color paste, and application and the use method of the resin color paste. The water-based acrylate resin color paste is a polymer with a core-shell structure, wherein an inner core polymer is a composition of an acrylate polymer and a pigment, and a shell polymer is a water-basedacrylate polymer synthesized in an emulsion polymerization manner. According to the invention, the pigment is added in a reaction process, a molecular chain in a polymer solution synthesized by solution polymerization and the pigment are dispersed more uniformly and combined more tightly, and after the polymer is self-emulsified to form emulsion particles, the pigment is uniformly dispersed and wrapped in the emulsion particles; and thus, the situation of phase separation caused by nonuniform pigment dispersion and pigment aggregation in the film forming process of the paste is reduced, and the color fastness of the water-based acrylate resin color paste is greatly improved.

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...
