Multipurpose water-based high-speed packaging adhesive and preparation method thereof

The invention discloses a multipurpose water-based high-speed packaging adhesive and a preparation method thereof, and belongs to the technical field of adhesives for cigarettes. The invention relates to a modified VAE (Vinyl Acetate Ethylene) emulsion, which is prepared from the following components in parts by weight: 72 to 88 parts of modified VAE emulsion, 10 to 15 parts of modified polyvinyl alcohol aqueous solution, 0.3 to 0.5 part of defoaming agent, 0.3 to 0.9 part of tackifying resin, 1 to 5 parts of plasticizer, 0.4 to 1 part of humectant and 0.2 to 0.4 part of preservative. Polyvinyl alcohol is modified to increase the dissolving property and shear resistance, and is compounded with commercially available modified VAE emulsion, defoaming agent, tackifier, plasticizer, humectant and preservative, so that the viscosity of the modified VAE emulsion is increased; by means of the synergistic effect of all the components, the initial viscosity, the moisturizing capacity, the redissolving performance and
