Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the present embodiment provides a pressure-resistant corrugated cardboard, including an upper layer of paper 1, a lower layer of paper 2 and a corrugated medium of paper 3, the corrugated medium of paper 3 is fixedly connected to the upper surface of the lower layer of paper 2, the corrugated medium of paper 3 is fixedly connected to a middle layer of paper 4, the middle layer of paper 4 is fixedly connected to a plurality of outer paper tubes 5, the inner wall of the outer paper tube 5 is fixedly connected to a plurality of connecting plates 6, one end of the connecting plate 6 far away from the outer paper tube 5 is fixedly connected to an inner paper tube 7, a cavity 8 is formed between two adjacent connecting plates 6, a desiccant 9 is provided in the cavity 8, a through hole 10 is provided on the middle layer of paper 4, the desiccant 9 in the cavity 8 has a good moisture absorption effect, at this time, moisture on the upper layer of paper 1, the lower layer of paper 2 and the corrugated paper 3 is absorbed by the desiccant 9 through the air holes 301 and the through holes 10, thereby keeping the corrugated medium dry, and the upper layer of paper 1 is fixedly connected to the upper surface of the outer paper tube 5.

As shown in figures 1 and 2, the outer paper tubes 5 and the inner paper tubes 7 are both cylindrical structures, and the two adjacent outer paper tubes 5 are fixedly connected, so that the middle layer plate and the upper layer plate are fixed more firmly.
