The invention provides gold print paste and a preparation method thereof. The gold print paste is prepared from, by weight, acrylic emulsion, hot melting powder, a curing agent, a thickening agent and a defoaming agent; the acrylic emulsion is mainly prepared from, by weight, 0.8-1.8 parts of emulsifying agent, 60-70 parts of soft monomer, 20-35 parts of hard monomer, 0.5-3 parts of cross-linking monomer, 3-5 parts of functional monomer, 0.15-0.4 part of initiating agent, 0.3-1.4 part of neutralizing agent, 0.3-0.5 part of pH buffering agent, 0-2.4 parts of adipic acid dihydrazide and 88-115 parts of deionized water. The gold print paste can serve as an adhesive between gold print foil and any cloth, the print making process is easy to implement, prints are not tacky, printing temperature is low, printed textile made through the gold print paste has super-high washable performance, achieves a mirror surface effect and is soft in hand feeling, and the gold print paste has good application prospects in the field of textile and paper products.
