Synthesis technology of water-emulsion fluorescent pigment

Abstract

The invention relates to the field of fluorescent pigment, in particular to a synthesis technology of a water-emulsion fluorescent pigment, which mainly comprises an emulsification process, a seed emulsion polymerization process, a dropping reaction process and a post-treatment process; the invention comprises the following steps: firstly preparing emulsified liquid through the emulsification process, getting 5 to 20 percent of the total prepared emulsified liquid to synthesize the seed emulsion, then performing the dropping reaction process and the post-treatment process, so that the stability of the synthesis technology of the integrated water-emulsion fluorescent pigment can be ensured, thereby reducing the viscosity of the product and improving the transparency of resin and fluorescence of the product. Therefore, the water-emulsion fluorescent pigment prepared by the synthesis technology of invention has the advantages of low viscosity and high fluorescence.

[0003] The traditional synthesis process of water-emulsion fluorescent pigments is to directly emulsify the reaction raw materials, and the emulsion obtained by emulsification is directly added to the initiator to continue the reaction to obtain the finished water-emulsion fluorescent pigments. However, the water-emulsion fluorescent pigments prepared by this synthesis process Fluorescent pigments have high viscosity and poor fluorescence
