[0008] Preferably, the moisture-proof layer is a silica gel layer.

[0009] Preferably, the load-bearing layer is a trapezoidal corrugated layer.

[0010] Preferably, the pressure-resistant layer is a honeycomb board layer.

[0011] Furthermore, the antistatic layer is an antistatic nylon layer.

[0012] Preferably, the waterproof layer is a polyethylene film layer.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The utility model, when carrying heavy objects, is supported by the upper and lower load-bearing layers, and the weight is evenly distributed to the pressure-resistant layer to increase the force-bearing area, and then supported by multiple support columns to share the weight, so that the load-bearing capacity of the cardboard is greatly increased, and the heavy objects are prevented from crushing the cardboard, and the safety of the items on the cardboard is protected.

[0015] 2. According to the utility model, when rain falls on the cardboard, it will be blocked by the waterproof layer, which can effectively improve the waterproofness of the cardboard, and prevent the cardboard from getting damp and softening when it comes into contact with water, thereby damaging the goods inside and affecting the quality of the goods inside.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a load-bearing waterproof paperboard.

[0024] The utility model provides Figure 1-3The load-bearing waterproof cardboard shown includes a cardboard box 1, the upper and lower inner walls of the cardboard box 1 are respectively fixedly connected with a moisture-proof layer 2, the sides of the two moisture-proof layers 2 close to each other are respectively fixedly connected with a load-bearing layer 3, and a pressure-resistant layer 4 is fixedly connected between the two load-bearing layers 3. A plurality of load-bearing columns 5 are arranged inside the cardboard box 1, and the two ends of the plurality of load-bearing columns 5 respectively penetrate the two moisture-proof layers 2, the two load-bearing layers 3 and the pressure-resistant layer 4 and are fixedly connected to the upper and lower inner walls of the cardboard box 1, the outer wall of the cardboard box 1 is fixedly connected with an antistatic layer, and the outer wall of the antistatic layer is fixedly connected with a waterproof layer 6.

[0025] When carrying heavy objects, the upper and lower load-bearing layers 3 bear the gravity, and the weight is evenly distributed to the pressure-resistant layer to increase the force-bearing area. The weight is then supported by multiple support columns to share the weight, which greatly increases the load-bearing capacity of the cardboard, avoids heavy objects from crushing the cardboard, and protects the safety of items on the cardboard.

[0026] In order to make the cardboard moisture-proof, Figure 1 As shown, the moisture-proof layer 2 is a silicone layer.

[0027] When the cardboard is placed in a cold and humid place, the silica gel layer will absorb moisture in the air to prevent damage to the cardboard due to moisture.

[0028] In order to make the cardboard more load-bearing, Figure 1 As shown, the load-bearing layer 3 is a trapezoidal corrugated layer, and the pressure-resistant layer 4 is a honeycomb board layer.

[0029] When bearing heavy objects, the honeycomb board layer is sandwiched between two trapezoidal corrugated layers, which has the advantages of high strength, strong load-bearing performance, good structural stability and not easy to deform.

[0030] To protect the cardboard from static electricity, Figure 1 As shown, the antistatic layer 6 is an antistatic nylon layer.

[0031] An anti-static nylon layer is provided to prevent damage to electrical appliances and other items caused by static electricity generated by a dry external environment or during transportation.

[0032] Finally, in order to make the cardboard waterproof, such as Figure 1 As shown, the waterproof layer 7 is a polyethylene film layer.

[0033] When rain falls on the cardboard, it will be blocked by the polyethylene film layer, which can effectively improve the waterproofness of the cardboard, prevent the cardboard from getting damp and softening when it comes into contact with water, and damage the products inside, affecting the quality of the products inside.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
