[0014] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model relates to a moisture-proof corrugated cardboard, comprising a corrugated cardboard body 1, a waterproof rubber frame 2 fixedly connected to the outer edge of the corrugated cardboard body 1, a circular sticker 3 fixedly affixed to the top center of the corrugated cardboard body 1, a triangular indicator 4 marked at the top center of the circular sticker 3, the corrugated cardboard body 1 comprising a main layer 101, a moisture-proof bottom layer 102 fixedly connected to the bottom of the main layer 101, a reinforcing layer 103 fixedly connected to the top of the main layer 101, a moisture-proof protective layer 104 fixedly connected to the top of the reinforcing layer 103, an outer protective layer 105 fixedly connected to the top of the moisture-proof protective layer 104, and the circular sticker 3 fixedly affixed to the top center of the outer protective layer 105, wherein the moisture-proof bottom layer 102 is made of a waterproof film and the reinforcing layer 103 is made of kraft paper; The moisture-proof protective layer 104 includes a middle moisture-proof board layer 1041, a lower moisture-proof layer 1042 fixedly connected to the bottom of the middle moisture-proof board layer 1041, and the bottom of the lower moisture-proof layer 1042 fixedly connected to the top of the reinforcing layer 103. A higher moisture-proof layer 1043 is fixedly connected to the top of the middle moisture-proof board layer 1041, and the top of the higher moisture-proof layer 1043 is fixedly connected to the bottom of the outer protective layer 105. The middle moisture-proof board layer 1041 is made of moisture-proof fiberboard, the lower moisture-proof layer 1042 is made of PVC plastic waterproof cloth, and the upper moisture-proof layer 1043 is made of EPDM rubber waterproof cloth. The outer protective layer 105 includes a corrosion-resistant protective layer 1051, and the bottom of the corrosion-resistant protective layer 1051 is fixedly connected to the top of the moisture-proof upper layer 1043. The top of the corrosion-resistant protective layer 1051 is fixedly connected to a wear-resistant protective layer 1052, and a circular sticker 3 is fixedly affixed to the top center of the wear-resistant protective layer 1052. The corrosion-resistant protective layer 1051 is made of ceramic coating material, and the wear-resistant protective layer 1052 is made of wear-resistant and corrosion-resistant polymer material obtained by combining high-performance wear-resistant ceramic particles and modified toughening resin.

[0015] In use, the corrugated cardboard body 1, waterproof rubber border 2, circular sticker 3, triangular indicator 4, main body layer 101, moisture-proof bottom layer 102, reinforcing layer 103, moisture-proof protective layer 104, and outer protective layer 105 interact to achieve better moisture resistance during actual use, thus improving the service life of the corrugated cardboard and enhancing its practicality.

The wear-resistant protective layer 1051 and the wear-resistant and corrosion-resistant polymer material 1052, which is made of high-performance wear-resistant ceramic particles and modified toughening resin composite, can form corrosion-resistant and wear-resistant protection on the top of the moisture-proof protective layer 104, avoiding damage caused by external corrosive liquids and external friction, so as to further improve the moisture resistance of the corrugated cardboard body 1, and also enhance the corrosion resistance and wear resistance of the corrugated cardboard body 1. In this case, the waterproof rubber frame 2 can form moisture-proof protection on the four sides of the corrugated cardboard body 1, preventing moisture from affecting its interior. Through the cooperation of the above structures, the corrugated cardboard can achieve better moisture resistance in actual use, improve the service life of the corrugated cardboard, and thus achieve better practicality.
