Preparation method of biobased water-borne UV (ultraviolet) curing environment-friendly nail polish

The invention relates to a preparation method of biobased water-borne UV (ultraviolet) curing environment-friendly nail polish. The preparation method is characterized by comprising the following steps of weighing 30 to 50% of biobased water-borne UV curing environment-friendly nail polish resin, 5 to 10% of deionized water, 40 to 60% of pigment, 0.1 to 0.5% of wetting dispersant, 0.1 to 0.5% of flatting agent, 0.2 to 0.5% of defoaming agent, and 1.0 to 2.0% of thickener; adding the pigment, the wetting dispersant, the flatting agent, the defoaming agent and the deionized water into a ball mill to mill, so as to obtain a color paste a; adding the biobased water-borne UV curing environment-friendly nail polish resin into the color paste a, stirring at high speed, adding the thickener, and filtering by a 200-mesh filter net, so as to obtain the biobased water-borne UV curing environment-friendly nail polish. The prepared biobased water-borne UV curing environment-friendly nail polish has the characteristics tha
