Preparation method of printing gloss oil taking amino-terminated hyperbranched self-assembled polyamide as main component

The invention belongs to the technical field of high polymer materials, and relates to a preparation method of printing gloss oil taking amino-terminated hyperbranched self-assembled polyamide as a main component, which comprises the following steps: firstly, preparing halogenated tert-butyl dimethyl ester; then, hexamethylenetetramine/NaHCO3 is added into the prepared halogenated tert-butyl dimethyl ester, and amino tert-butyl dimethyl ester is obtained; then adding carboxylic acid or adding a K2CO3/methanol solution to obtain a hyperbranched prepolymerized monomer ABn; adding a catalyst to obtain amino-terminated hyperbranched polyamide; the preparation method comprises the following steps: adding the polyol, the polyisocyanate and the chain extender into the solvent, stirring and dissolving, and continuously adding the acrylic diluent, the photoinitiator, the flatting agent and the wax slurry to obtain the printing gloss oil. The prepared printing gloss oil shows excellent drying and curing efficiency, and
