The invention provides glue for a drying-free paper tube, a preparation method of the glue and the drying-free paper tube, and belongs to the technical field of papermaking. The glue for the drying-free paper tube is prepared from the following components in parts by weight: 50-60 parts of deionized water, 3-7 parts of polyvinyl alcohol, 0.1-0.3 parts of an external cross-linking agent, 0.3-0.4 parts of a pH (Potential of Hydrogen) regulator, 0.1-0.15 parts of an initiator, 30-40 parts of vinyl acetate, 2-4 parts of vinyl versatate, 0.3-0.45 parts of an internal cross-linking agent, 5-10 parts of filler and 0.45-2.3 parts of an auxiliary agent. The glue provided by the invention has the characteristics of good flowability, high bonding strength, high and low temperature resistance, excellent waterproof performance, high initial bonding speed and the like, a drying step can be omitted for a paper tube prepared by coating paper tube raw paper with the glue, and full-automatic production is realized. 本发明提供了一种用于免
