Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, and in particular to a high-toughness double-corrugated paper core corrugated paper for the preservation of cultural relics. Background Technology

[0002] Corrugated cardboard is a multi-layered bonded structure, consisting of at least one layer of corrugated core paper and one layer of cardboard. It possesses high mechanical strength, enabling it to withstand impacts and drops during handling. The actual performance of a corrugated box depends on three factors: the properties of the core paper and cardboard, and the box's inherent structure.

[0003] The existing single-layer corrugated core is insufficient for cushioning. When used for packaging fragile items such as ceramics and calligraphy and paintings, they are easily damaged by collisions during transportation. Therefore, this application provides a high-toughness double-walled corrugated paper core for the preservation of cultural relics to meet the needs. Utility Model Content

[0007] The top of the buffer layer is bonded with an insulation layer, and the top of the insulation layer is bonded with a fireproof layer.

[0008] The reinforcing ribs are arranged in a grid pattern, and the inner part of the reinforcing ribs is filled with EPE pearl cotton cushioning material.

[0009] The top of the fireproof layer is bonded with a moisture-proof layer, which is made of polyethylene waterproof membrane.

[0010] The top of the moisture-proof layer is bonded with a reinforcing layer, and the surface of the reinforcing layer is coated with a nano-ceramic wear-resistant coating.

[0011] The first and second corrugated cores are made of symmetrically arranged corrugated cardboard and filled with a high-elasticity polyester fiber mesh.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] 1. In the above solution, the reinforcing ribs are set in a grid pattern and filled with EPE pearl cotton cushioning material to achieve multi-directional pressure resistance and energy absorption. Combined with the buffer layer, it effectively disperses the impact of external forces, making it suitable for long-distance transportation of fragile cultural relics and reducing transportation damage.

[0014] 2. In the above scheme, the top of the buffer layer is bonded with an insulation layer, and the top of the insulation layer is bonded with a fireproof layer.
