Abstract

The invention relates to a preparation method of fluorescent coloring particles, and aims to provide high-weather-resistance fluorescent coloring particles and a preparation method thereof. Compared with domestic and foreign products prepared by the prior art, the fluorescent coloring particles prepared by the method have high weather resistance, and can be taken as fluorescent pigments to be applied to the fields of plastics, plastic cement, coatings, ink and the like. According to the technical scheme, the preparation method of the high-weather-resistance fluorescent coloring particles comprises the following steps in sequence: (1) preparing high-weather-resistance nanoscale polyacrylic resin particles; (2) preparing a fluorescent coloring particle carrier resin prepolymer; (3) coloring and emulsifying the carrier resin; (4) curing fluorescent coloring resin particles.

Description

technical field [0001] The invention relates to a method for preparing fluorescent colored particles, in particular to a method for preparing highly weather-resistant fluorescent colored particles by using nano-scale highly weather-resistant polyacrylic resin modified amino resin particles. Background technique [0002] Fluorescent colored particles are widely used in the fields of plastics, plastics, coatings, inks and the like because of their bright colors. Compared with ordinary colorants, the products prepared by it are more eye-catching and favored by the market. Therefore, there are many literatures at home and abroad about the research on the preparation technology of this type of product; the basic preparation technology is obtained by dissolving organic fluorescent dyes in the carrier resin to form a solid solution, and the carrier resin is mainly polyester, polyamide , amino resins, polyacrylates or their composites. The technical methods mainly include polyconde...
