1. A method for preparing a multi-phase structured UV-curable powder coating resin, comprising:
(1) obtaining an emulsion of a liquid UV resin by heating the liquid UV resin and an emulsifier, dispersing and adding deionized water for emulsification;
(2) melting and dispersing a solid UV resin, a phase change agent, an emulsifier, and the deionized water until fully molten and homogeneously dispersed; adding the emulsion of the liquid UV resin with stirring to thoroughly mix; temperature is lowered during the stirring to obtain a suspension of the multi-phase structured UV-curable powder coating resin;
(3) press filtering the suspension of the UV-curable powder coating resin to obtain a filter cake;
(4) drying and classifying the filter cake to obtain the multi-phase structured UV-curable powder coating resin.
