[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0020] Such as Figure 1 - Figure 2As shown in the figure, an environmentally friendly fold-resistant single-sided coated composite cardboard includes a lower bottom plate 1. A corrugated plate 2 is provided on the upper surface of the lower bottom plate 1, and the corners of the corrugated plate 2 are rounded. The advantage of this setting is that through the setting of the corrugated plate 2, while reducing the weight of the single-sided coated composite cardboard, the strength of the single-sided coated composite cardboard can be ensured. Also, when the single-sided coated composite cardboard is bent, the rounded corners at the edges of the corrugated plate 2 can reduce the wear on the corrugated plate 2 and improve the service life of the corrugated plate 2.
[0021] Furthermore, a thickened layer 201 is provided in the middle of the corrugated plate 2, and the thickness of the thickened layer 201 is greater than that of the corrugated plate 2. An upper cover plate 202 is provided above the corrugated plate 2. The advantage of this setting is that through the setting of the thickened layer 201, the anti-bending ability of the single-sided coated composite cardboard can be improved.
[0022] Furthermore, a bending groove 203 is opened in the middle of the surface of the upper cover plate 202, and the bending groove 203 is rectangular. The advantage of this setting is that through the setting of the bending groove 203, when the single-sided coated composite cardboard is bent, it can play a guiding role, thereby improving the service life of the single-sided coated composite cardboard.
[0023] As Figure 3 - Figure 4 shown in the figure, an adhesion layer 3 is provided on the surface of the upper cover plate 202, and the adhesion layer 3 is composed of transparent glue. A waterproof film 301 is provided on the surface of the adhesion layer 3, and the waterproof film 301 is composed of polytetrafluoroethylene. The advantage of this setting is that the setting of the waterproof film 301 can improve the waterproof ability of the single-sided coated composite cardboard, and at the same time ensure the dryness of the single-sided coated composite cardboard and the anti-bending ability of the single-sided coated composite cardboard.
[0024] Furthermore, anti-collision blocks 4 are provided at the four corners of the lower bottom plate 1, and the anti-collision blocks 4 are L-shaped. The anti-collision blocks 4 are composed of hollow cardboard, and the corners of the anti-collision blocks 4 are rounded. The advantage of this setting is that through the setting of the anti-collision blocks 4, the single-sided coated composite cardboard can be protected.
[0025] Working principle: When using this environmentally friendly fold-resistant single-sided coated composite cardboard, first, when the single-sided coated composite cardboard needs to be bent, the upper cover plate 202, the lower bottom plate 1, and the corrugated plate 2 can be bent along the bending groove 203. The thickened layer 201 increases the bending resistance of the single-sided coated composite cardboard. When the single-sided coated composite cardboard is collided, the hollow anti-collision blocks 4 at the four corners of the single-sided coated composite cardboard deform to absorb the impact received and protect the coated composite cardboard. This is the working principle of this environmentally friendly fold-resistant single-sided coated composite cardboard.
