Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Example:
[0021] like Figures 1 to 3 As shown, a high-resilience multi-layer corrugated cardboard includes: a main body 1, an intermediate layer 103 inside the main body 1, a first corrugated layer 102 and a second corrugated layer 104 fixedly connected to the inside of the main body 1 and on both sides of the intermediate layer 103, an upper paper surface 101 fixedly connected to the side of the first corrugated layer 102 away from the intermediate layer 103, and a lower paper surface 105 fixedly connected to the side of the second corrugated layer 104 away from the intermediate layer 103. Multiple sets of equally spaced cylindrical columns 4 are fixedly connected inside the intermediate layer 103. Hard corrugated layers 2 are provided inside both the first corrugated layer 102 and the second corrugated layer 104. Spacer layers 3 are provided on both sides of the cylindrical columns 4, between the first corrugated layer 102 and the upper paper surface 101, and between the second corrugated layer 104 and the lower paper surface 105. Spacer layers 3 are provided inside the first corrugated layer 102 and the second corrugated layer 104 and on both sides of the hard corrugated layer 2. Thickened layers 201 are fixedly connected to each side. When this high-resilience multi-layer corrugated cardboard is put into use, the layers within the main body 1 are bonded together with environmentally friendly high-viscosity adhesive. The multi-layer structure increases the strength of the main body 1, reduces the possibility of damage to the main body 1, improves practicality, and extends service life. The cylindrical column 4, the first wave layer 102, and the second wave layer 104 are all smooth non-linear structures. When subjected to external impact, the cardboard can have good cushioning performance and rebound the external force. The multi-layer design improves the rebound performance and reduces the possibility of damage to the main body 1. The hard wave layer 2 and the two sets of thickened layers 201 improve the strength of the first wave layer 102 and the second wave layer 104, thereby improving the strength and resilience of the main body 1, and further improving the overall stability and durability of the cardboard, improving practicality, and extending service life.

[0023] In the embodiment, the inner sides of the upper paper face 101 and the lower paper face 105 away from each other are fixedly connected with the resilience enhancement layer 501, which is a honeycomb-shaped paper core paperboard. When the high-resilience multilayer paper core corrugated paperboard is put into use, the honeycomb layer can quickly recover the deformation after being pressed, the resilience is improved, the practicability is improved, and the service life is prolonged.
[0024] In the embodiment, the inner sides of the upper paper face 101 and the lower paper face 105 away from each other are fixedly connected with the elastic layer 502, which is a V-shaped paper core paperboard. When the high-resilience multilayer paper core corrugated paperboard is put into use, the V-shaped paper core paperboard forms a three-dimensional grid buffer structure with multiple V-shaped angles, so that the external force can be rebounded, the practicability is improved, and the service life is prolonged.
[0025] In the embodiment, the sides of the upper paper face 101 and the lower paper face 105 away from each other are provided with the waterproof layer 6, which is an acrylic-based paint. The acrylic-based paint is a high-resilience waterproof paint, has high tensile ductility, can cover fine cracks, adapt to temperature difference deformation, has high elastic resistance to cracking, and can reduce the possibility of deformation of the corrugated paper due to extrusion during transportation when the high-resilience multilayer paper core corrugated paperboard is put into use. It can also prevent water, prolong the service life.
