The invention relates to water-based peelable paint. A manufacturing process of the water-based peelable paint comprises the following steps of A, a reaction kettle process, B, an emulsification cylinder process, C, a reaction part and D, a post processing part. Through the steps of a method, the finally made water-based peelable paint can be finally made into 100 to 120 parts by weight of crylic acid emulsion with the solid content being 40 to 45 percent. The water-based peelable paint has the innovation point that any auxiliary agents do not need to be added; a self created special polymerization process and raw materials are used for realizing the characteristics of high self inner cohesion force and low attaching force of resin, in addition, the water-resistant acid-resistant and alkali-resistant performance is excellent, certain toughness and elasticity are realized, and the self peelable performance is realized.
