Zusammenfassung:The invention relates to a paper surface conditioning agent, and provides an environmentally-friendly cationic polyacrylate, and a preparation method and an application thereof to solve the problems of poor product storage stability, poor stability of a prepared coating liquid, bad impurity ion interference resistance, insufficient foamability of the coating liquid, and environmental pollution due to the use of aluminum sulfate during surface sizing of present sizing agents. The environmentally-friendly cationic polyacrylate is prepared by using 5-100 parts of a natural polymer emulsifier, 1-55 parts of a hard monomer, 5-55 parts of a soft monomer, 0.1-15 parts of a cationic monomer, 0.1-10 parts of a stabilizer, 0.01-10 parts of an initiator, 0.01-10 parts of an initiator B, 0.01-10 parts of a molecular weight regulator, 0.01-20 parts of an antifoaming agent, and water, wherein water is added to make the solid content reach 25-30%. The above sizing agent produced in the invention has the advantages of low co
