The invention discloses a preparation method of a block copolymer modified acrylic emulsion for denim pulp. The water-based adhesive comprises deionized water, a preservative, a defoaming agent, a buffering agent, an emulsifier, an initiator, a block copolymer, methyl methacrylate, butyl acrylate, hydroxyethyl acrylate, itaconic acid, diacetone acrylamide, adipic acid dihydrazide, methacrylamide ethyl ethylene urea, a preservative and the like. The milk white liquid with blue fluorescence is prepared through a pre-emulsification technology, the viscosity is 200-500 mPa.s, the solid content is 48%-52%, a film forming matter is colorless and transparent, the pH is 7-8, the emulsion has the advantages of being high in adhesive force, good in water resistance and good in toughness, the preparation method is convenient to operate, water serves as a dispersion medium, harm to human bodies and the environment is avoided, and the production environment is safe. 本发明公开了一种牛仔浆用嵌段共聚物改性丙烯酸乳液的制备方法，其由去离子水、防腐剂、消泡剂、缓冲剂、乳化剂、引发剂
