Description

Technical Field

[0001] The utility model relates to the technical field of white cardboard, in particular to a long-life composite white cardboard. Background Art

[0002] White cardboard is a common paperboard, usually used to make packaging boxes, food boxes, cards and other products. Its name comes from its white surface and single-layer card texture. This type of paperboard usually has a certain thickness and strength, suitable for applications that require a certain amount of support.

[0003] At present, some existing white cardboards have relatively simple internal and external structures, so the protective effect is poor. They are easily affected by the external environment when in use, which causes great damage to the service life of the cardboard itself after use, and is not conducive to continuous use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a long-life composite white card paper, which improves the protective effect of the card paper base layer, thereby increasing the overall service life of the white card paper and facilitating continuous use.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A long-life composite white cardboard comprises a cardboard base layer, the inner wall of the cardboard base layer is fixedly connected to a tough layer, the outer wall of the cardboard base layer is fixedly connected to a moisture-proof layer, the upper and lower ends of the moisture-proof layer are fixedly connected to wear-resistant and anti-fouling layers, an antibacterial layer is filled between the outer wall of the cardboard base layer and the inner wall of the moisture-proof layer, and a flame-retardant layer is filled between the inner wall of the cardboard base layer and the outer wall of the tough layer.

[0007] Furthermore, the thickness of the cardboard base layer is 1.2 mm, and the thickness of the flame retardant layer is 0.1 mm.

[0008] Furthermore, the thickness of the moisture-proof layer is 1.34 mm, and the thickness of the antibacterial layer is 0.3 mm.

[0009] Furthermore, the thickness of the wear-resistant and anti-fouling layer is 0.83 mm.

[0010] The utility model has the following beneficial effects:

[0011] In the utility model, a flame retardant layer and a toughness layer are arranged on the inner wall of the cardboard base layer, and an antibacterial layer, a moisture-proof layer, and a wear-resistant and anti-fouling layer are arranged on the outer wall thereof, so that the flame retardant, toughness, antibacterial, moisture-proof, wear-resistant and anti-fouling effects of the cardboard base layer can be improved, thereby enhancing the protective effect of the cardboard base layer, and further increasing the overall service life of the white cardboard, which is conducive to continuous use.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Reference Figure 1 The utility model provides an embodiment: a long-life composite white cardboard, including a cardboard base layer 1, a toughness layer 3 is fixedly connected to the inner wall of the cardboard base layer 1, a moisture-proof layer 5 is fixedly connected to the outer wall of the cardboard base layer 1, and wear-resistant and anti-fouling layers 6 are fixedly connected to the upper and lower ends of the moisture-proof layer 5. An antibacterial layer 4 is filled between the outer wall of the cardboard base layer 1 and the inner wall of the moisture-proof layer 5, and a flame-retardant layer 2 is filled between the inner wall of the cardboard base layer 1 and the outer wall of the toughness layer 3.

[0017] To further explain, the toughness layer 3 is made of glass fiber, so that the toughness layer 3 has good toughness, thereby improving the overall toughness of the cardboard base layer 1; the flame retardant layer 2 is made of aluminum hydroxide, which can improve the flame retardant effect of the cardboard base layer 1; the moisture-proof layer 5 is mixed with montmorillonite powder, which can make the outside of the cardboard base layer 1 have good moisture resistance; the antibacterial layer 4 is mixed with copper ion antibacterial agent, which can effectively inhibit the reproduction of bacteria outside the cardboard base layer 1; the wear-resistant and anti-fouling layer 6 is a film layer made of polypropylene and covers the two ends of the outermost layer of the cardboard base layer 1, which can increase the wear resistance and oil resistance of the white cardboard.

[0018] Specifically, the thickness of the cardboard base layer 1 is 1.2 mm, the thickness of the flame retardant layer 2 is 0.1 mm, the thickness of the moisture-proof layer 5 is 1.34 mm, the thickness of the antibacterial layer 4 is 0.3 mm, and the thickness of the wear-resistant and anti-fouling layer 6 is 0.83 mm.

[0019] Working principle: First, the toughness layer 3 is made of glass fiber, so that the toughness layer 3 has good toughness, which can improve the overall toughness of the cardboard base layer 1 and is not easy to be bent and deformed. Secondly, a flame retardant layer 2 is filled between the cardboard base layer 1 and the toughness layer 3. The flame retardant layer 2 is made of aluminum hydroxide, which can improve the flame retardant effect of the cardboard base layer 1. Then, the moisture-proof layer 5 is mixed with montmorillonite powder, which can make the outside of the cardboard base layer 1 have good moisture resistance. An antibacterial layer 4 is filled between the cardboard base layer 1 and the moisture-proof layer 5. The antibacterial layer 4 is mixed with copper ion antibacterial agent, which can effectively inhibit the reproduction of bacteria outside the cardboard base layer 1 and keep the paper hygienic. The wear-resistant and anti-fouling layer 6 is a film layer made of polypropylene and covers the two ends of the outermost layer of the cardboard base layer 1, which can increase the wear resistance and oil resistance of the white cardboard.

[0020] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
