The invention discloses a method for preparing cross-linked acrylic resin polymer-wrapped pigment yellow fluorescent nanoparticles: uniformly mix the prepared water phase and the prepared organic phase, the mass of the organic phase is 1-20% of the mass of the water phase, Form a uniform emulsion; under the protection of nitrogen, add the aqueous solution of the configured initiator to the uniform emulsion, raise the temperature to 40-100°C, keep warm for 3-12h, and obtain the emulsion; add hydrazine hydrate to the emulsion, 40-100°C Insulate for 1-5 hours to obtain an aqueous dispersion, high-speed centrifugation, Soxhlet extraction, washing with water, and drying to obtain the cross-linked acrylic resin polymer-wrapped pigment yellow fluorescent nanoparticles. The preparation method of cross-linked acrylic resin polymer-wrapped pigment yellow fluorescent nanoparticles of the present invention does not require the process of mechanically dispersing pigments, reduces the difficulty of controlling the particle size of pigment microcapsules, and has controllable nanometer particle size, simple preparation, short process flow, and post-processing. Handling is simple. |
