The present invention relates to the technical field of adhesive resins, in particular to an adhesive resin used for multilayer barrier sheets, a preparation method thereof, and a barrier structure. Adhesive resin for multilayer barrier sheet, including the following components in parts by weight: 0-40 parts of polystyrene, 20-40 parts of polyethylene, 5-40 parts of graft-modified polyethylene and benzene 15-50 parts of the ethylene-based block copolymer; the melt index of the styrene-based block copolymer is 1-40 g/10min; the melt index of the polyethylene is 0.1-5 g/10min. The adhesive resin of the present invention can have good compatibility and wettability for two layers of resins such as nylon layer and polystyrene layer, and at the same time, the adhesive resin can have excellent toughness through the combination of various components. |
