The invention discloses a function prepolymer and a preparation method and application thereof. The function prepolymer is a butyl acrylate polymer and prepared from a monomer, modified matter and an emulsifying agent through emulsion polymerization. A synthetic thickener, liquid disperse dye and the function prepolymer are mixed with water and evenly stirred to obtain printing paste; printing and drying of a polyester fabric are achieved through the obtained printing paste on a rotary screen printing machine or a mobile screen printing machine, then high-temperature processing is carried out on a tentering heat setting machine, and a printed polyester fabric is obtained. According to the technical scheme, the printing process is short, the hand feeling of the fabric is soft, postprocessing is not needed, a large amount of water and energy are saved, almost no wastewater is drained, processing equipment is conventional, and the printing processing technology is environmentally friendly.
