A plurality of equally spaced lower grooves are formed between the corrugated core paper layer and the lower support paper layer. Lower pressure-resistant blocks are arranged in each of the plurality of lower grooves. The cross sections of the upper pressure-resistant blocks and the lower pressure-resistant blocks are both triangular.
[0007] Preferably, the upper support paper layer and the upper pressure-resistant blocks are connected by an adhesive. The lower support paper layer and the lower pressure-resistant blocks are also connected by the adhesive.

DETAILED DESCRIPTION
[0016] See also Figures 1 to 2 A pressure-resistant and mildew-proof paperboard is shown, comprising an upper supporting paper layer 1, a corrugated core paper layer 2 and a lower supporting paper layer 3 are sequentially arranged at the bottom of the upper supporting paper layer 1, a mildew-proof layer 4 and an anti-permeability layer 5 are sequentially arranged at the top of the upper supporting paper layer 1, a plurality of equally distributed upper grooves 6 are formed between the corrugated core paper layer 2 and the upper supporting paper layer 1, and upper pressure-resistant blocks 7 are arranged in each of the upper grooves 6, a plurality of equally distributed lower grooves 8 are formed between the corrugated core paper layer 2 and the lower supporting paper layer 3, and lower pressure-resistant blocks 9 are arranged in each of the lower grooves 8, and the cross-sections of the upper pressure-resistant blocks 7 and the lower pressure-resistant blocks 9 are both triangular.
[0017] Furthermore, the upper supporting paper layer 1 and the upper pressure-resistant block 7 are connected by adhesive, and the lower supporting paper layer 3 and the lower pressure-resistant block 9 are also connected by the adhesive.
[0018] The adhesive is provided to ensure the stability of the positions of the upper pressure-resistant block 7 and the lower pressure-resistant block 9.
[0019] Further, the adjacent upper pressure-resistant blocks 7 and lower pressure-resistant blocks 9 are staggered.
[0020] Through the position distribution of the upper pressure-resistant blocks 7 and the lower pressure-resistant blocks 9, when the corrugated core paper layer 2 is squeezed, the upper pressure-resistant blocks 7 and the lower pressure-resistant blocks 9 can approach each other better.
[0021] Further, a wear-resistant layer 10 is provided at the bottom of the lower support paper layer 3.
[0022] The wear-resistant layer 10 is set as a wear-resistant paper layer to provide wear-resistant protection for the inner layer of the cardboard.
[0023] Further, a waterproof layer 11 is provided on the top of the anti-permeation layer 5.
[0024] The waterproof layer 11 is set as a waterproof film, such as a polymer film, to ensure the waterproof effect of the outer layer of the cardboard.
[0025] Further, the anti-permeation layer 5 is set as an asphalt coating layer.
[0026] Through the asphalt coating layer, the anti-permeation effect of the outer surface of the cardboard can be ensured.
[0027] Further, the mold-proof layer 4 is set as a plant fiber coating layer.
[0028] Through the good mold-proof effect of the plant fiber coating layer, the mold-proof effect of the outer part of the cardboard can be ensured.
[0029] When the present utility model is in use, through the upper support paper layer 1, the corrugated core paper layer 2 and the lower support paper layer 3, the three-layer structure of the cardboard is realized, and the pressure resistance performance of the cardboard is initially improved. Upper pressure-resistant blocks 7 are arranged in a plurality of upper grooves 6, and lower pressure-resistant blocks 9 are arranged in a plurality of lower grooves 8. When the upper support paper layer 1 or the lower support paper layer 3 is squeezed, the adjacent upper pressure-resistant blocks 7 and lower pressure-resistant blocks 9 approach each other. Through the contact force after the upper pressure-resistant blocks 7 and the lower pressure-resistant blocks 9 approach each other and the stability of the triangular cross-section of the pressure-resistant blocks, the stability of the corrugated core paper layer 2 is better, and it is not easy to be deformed under pressure, further improving the pressure resistance performance of the cardboard. Through the waterproof layer 11, the anti-permeation layer 5 and the mold-proof layer 4, the moisture in the environment can be protected layer by layer, ensuring the mold-proof effect of the cardboard.
[0030] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
