Abstract

The invention discloses a composite paperboard structure with excellent impact resistance. The composite paperboard structure comprises a honeycomb paperboard I, wherein a honeycomb paperboard II is arranged on the honeycomb paperboard I; strip-type elastic pads which are arrayed in parallel are arranged between the honeycomb paperboard I and the honeycomb paperboard II; a plastic air bag is arranged in a clearance between every two adjacent elastic pads; an enhanced fiber layer is arranged on the upper surface of the honeycomb paperboard II; a stop membrane is arranged on the enhanced fiber layer; a thermoplastic elastomer layer is arranged on the stop membrane; PE (polyethylene) membrane layers are arranged in honeycombs of the honeycomb paperboard II in a covering manner, and PE membranes are filled with nano particle suspensions. The composite paperboard structure is excellent in impact resistance and rebound resilience; the impact resistance is greatly improved in the unit thickness; furthermore, the composite paperboard structure is easy to prepare and low in cost and can be widely applied to the field of paperboards needing to be subjected to impact resistance and resilience.

Description

technical field [0001] The invention relates to the field of composite paperboard, in particular to a composite paperboard structure with excellent impact resistance. Background technique [0002] In the field of packaging boards, higher requirements are placed on the mechanical properties of the boards, especially the impact resistance. And due to the cheap nature of paper products, cardboard has been widely used. The cardboard with a special structure strengthens the mechanical properties of the cardboard. For example, corrugated cardboard with a wave structure has good strength, and the corrugated cardboard with a peak and nest structure has excellent cushioning properties. Multi-layered cardboard is required to improve its performance, and this will make the cardboard thicker, greatly increasing the weight of the package, and after reaching a certain thickness, increasing the number of cardboard layers will not improve the performance. . Therefore, finding other ways...
