Referring to fig. 1 and 4, a corrugated paper includes an upper face sheet 110, a lower face sheet 120, and a support layer 200; the supporting layer 200 comprises a plurality of first ribs 210 and a plurality of second ribs 220, an included angle is formed between a single first rib 210 and a single second rib 220, the plurality of first ribs 210 are arranged in parallel, and the plurality of second ribs 220 are arranged in parallel; the support layer 200 is disposed between the upper sheet 110 and the lower sheet 120.

Set up crisscross first protruding muscle 210 and second protruding muscle 220 between last surface paper 110 and lower surface paper 120, when the corrugated paper received the impact, first protruding muscle 210 and second protruding muscle 220 absorbed the energy of impact, and the shock resistance who has greatly increased the corrugated paper improves the intensity of corrugated paper.

The utility model discloses an in the embodiment, under the condition that does not increase corrugated paper thickness, can strengthen the intensity of whole corrugated paper through first protruding muscle 210 and the protruding muscle 220 of second. Therefore, besides prolonging the service life of the corrugated paper, the material consumption can be saved, the weight can be reduced, and the cost can be reduced.

In the above embodiment, in order to ensure that the first ribs 210 and the second ribs 220 effectively prevent the corrugated paper from deforming when the product of the corrugated paper receives an impact, specifically, the strength of the material of the first ribs 210 and the second ribs 220 should be higher than that of the upper sheet 110 and the lower sheet 120.

In some embodiments, referring to fig. 1, the first rib 210 is provided with a groove, the second rib 220 is embedded in the groove, and referring to fig. 3, the first rib 210 and the second rib 220 are fixed to the lower surface paper 120120 in an adhesion manner, and the first rib 210 and the upper surface paper 110110 are fixed in an adhesion manner. In this embodiment, listen to and set up the recess on first protruding muscle 210, make second protruding muscle 220 imbed in the recess, make first protruding muscle 210 set up one of them plane smooth transition of grooved one side and second protruding muscle 220, make first protruding muscle 210 and second protruding muscle 220 can be fixed with last surface paper 110 or lower surface paper 120 simultaneously, improve the stability of the structure of whole corrugated paper.

In some embodiments, the corrugated paper further comprises a buffer layer, the buffer layer is a wave structure, and the buffer layer is disposed between the upper surface paper 110 and the support layer 200, and between the lower surface paper 120 and the support layer 200. The anti-buckling is controlled with the main of first protruding muscle 210 to second protruding muscle 220, specifically absorb the impact energy that can arouse the corrugated paper is crooked, in order to further improve the load intensity of corrugated paper, still include the buffer layer in the structure of corrugated paper, when receiving external impact, the energy is at first in transmitting the buffer layer through last surface paper 110 or lower surface paper 120, the buffer layer that is wave structure can absorb most impact, avoid the corrugated paper sunken, when the atress of corrugated paper can lead to the corrugated paper to take place to bend, first protruding muscle 210 and second protruding muscle 220 will undertake the effect of anti-buckling, make the corrugated paper keep original structure, avoid taking place to bend and warp.

In some embodiments, the supporting layer 200 further includes two layers of paper 230, the first rib 210 and the second rib 220 are disposed between the two layers of paper 230, and the first rib 210 and the second rib 220 are adhered to the paper 230. Specifically, referring to fig. 1, the buffer layer is directly adhered to the paper separating sheet 230, so that the adhesion area between the buffer layer and the supporting layer 200 is increased, the adhesion is more stable, the buffer layer is prevented from being directly adhered to the first convex rib 210 or the second convex rib 220, the adhesion area is too small, and the buffer layer is easily separated and dispersed in the using process.

In some embodiments, the upper and lower surfaces of the top sheet 110 are covered with a water repellent film. Corrugated paper belongs to paper products, then second protruding muscle 220, first protruding muscle 210 all belong to paper products, and paper products meet the water and can wet and lead to hardness reduction, through the waterproofing agent membrane, can keep out the part and remain the surface moisture at the corrugated paper, has guaranteed the intensity of corrugated paper to a certain extent.

In some embodiments, referring to fig. 2, the first rib 210 is disposed perpendicular to the second rib 220. The angle between the first rib 210 and the second rib 220 may be any angle, and preferably, the 90 degree arrangement is most effective.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
