Description

Technical Field

[0001] The utility model relates to the technical field of white cardboard, in particular to a long-lasting antibacterial and mildew-proof white cardboard. Background Art

[0002] White cardboard is a kind of white cardboard made of thick and firm pure high-quality wood pulp. It is calendered or embossed and is mainly used for printing substrates for packaging and decoration. According to the purpose, there are special special papers, such as single-sided coated white cardboard for cigarette packaging called cigarette card, uncoated base paper for liquid food packaging called liquid food packaging paper, various anti-counterfeiting label papers, etc. Others are coated white cardboard used to package various commodities, such as packaging wine bottles, cosmetics, medicines, health products, chocolate or desserts, dry foods, solidified or frozen foods, tea, coffee, clothing, toys, calligraphy and painting, game supplies, photography products, etc. However, no matter what kind of product is used for printing, there is a characteristic of frequent direct contact with people.

[0003] For example, a Chinese patent with publication (announcement) number CN215518164U discloses a long-lasting antibacterial and mildew-proof white cardboard, including a base paper layer, characterized in that a starch layer is provided at the lower end of the base paper layer, a lower antibacterial layer is provided at the lower end of the starch layer, a first core paper layer and a second core paper layer are provided at the upper end of the base paper layer, a surface paper layer is provided at the upper end of the second core paper layer, an upper antibacterial layer is provided at the upper end of the surface paper layer, and an upper coating layer is provided at the upper end of the upper antibacterial layer.

[0004] The long-lasting antibacterial and mildew-proof white cardboard of the above technical solution has poor structural strength and durability, thereby reducing the practicality of the white cardboard. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a long-lasting antibacterial and mildew-proof white cardboard. The antibacterial and antibacterial effects of the white cardboard of the utility model are increased by setting an antibacterial layer, the corrosion resistance of the white cardboard of the utility model is increased by setting a corrosion-resistant layer, the flexibility of the white cardboard of the utility model is increased by setting a flexible layer, the elastic performance of the white cardboard of the utility model is increased by setting an elastic layer, the wear resistance of the white cardboard of the utility model is increased by setting a wear-resistant layer, and the waterproof effect of the white cardboard of the utility model is increased by setting a waterproof layer.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A long-lasting antibacterial and mildew-proof white cardboard, comprising:

[0008] The white cardboard body is composed of a bottom paper layer, a middle layer and a top paper layer. The bottom paper layer is arranged on one side of the middle layer, and the top paper layer is arranged on the other side of the middle layer.

[0009] The bottom paper layer is composed of an antibacterial layer and a corrosion-resistant layer; the middle layer is composed of a flexible layer and an elastic layer; and the top paper layer is composed of a wear-resistant layer and a waterproof layer.

[0010] As a further solution of the utility model, the antibacterial layer is made of natural bamboo fiber.

[0011] As a further solution of the utility model, the corrosion-resistant layer is made of polyurethane thermal insulation cotton.

[0012] As a further solution of the utility model, the flexible layer is made of ceramic fiber cotton.

[0013] As a further solution of the utility model, the elastic layer is made of low-density fibers.

[0014] As a further solution of the utility model, the wear-resistant layer is made of high-density fibers.

[0015] As a further solution of the utility model, the waterproof layer is made of polyethylene waterproof board.

[0016] Compared with the prior art, the long-lasting antibacterial and mildew-proof white cardboard of the utility model has the following beneficial effects:

[0017] 1. The utility model increases the antibacterial and antibacterial effects of the white cardboard of the utility model by providing an antibacterial layer, increases the corrosion resistance of the white cardboard of the utility model by providing a corrosion-resistant layer, increases the flexibility of the white cardboard of the utility model by providing a flexible layer, increases the elasticity of the white cardboard of the utility model by providing an elastic layer, increases the wear resistance of the white cardboard of the utility model by providing a wear-resistant layer, and increases the waterproof effect of the white cardboard of the utility model by providing a waterproof layer.

[0018] 2. The antibacterial layer in the utility model is made of natural bamboo fiber. Since the natural bamboo fiber retains the original antibacterial and antimicrobial effects of bamboo, and also has the characteristics of good moisture absorption and air permeability, wear resistance, etc., it increases the antibacterial and antimicrobial properties of the white cardboard of the utility model, thereby effectively preventing the white cardboard from mildewing.

[0019] 3. The corrosion-resistant layer in the utility model is made of polyurethane thermal insulation cotton. Since the polyurethane thermal insulation cotton not only has excellent properties such as heat insulation, sound insulation, and earthquake resistance, but also has excellent properties such as oil resistance, wear resistance, low temperature resistance, and aging resistance, it can maximize the corrosion resistance of the white cardboard of the utility model.

[0020] 4. The flexible layer of the utility model is made of ceramic fiber cotton. Since the ceramic fiber loose cotton has the characteristics of light weight, high strength, low thermal conductivity, good softness, corrosion resistance and small heat capacity, the flexibility, structural strength and corrosion resistance of the white cardboard of the utility model are greatly increased.

[0021] 5. The elastic layer of the utility model is made of low-density fiber. Since low-density fiber has the excellent characteristics of low weight, good elastic effect, reciprocating folding, and not easy to break, the elastic performance of the white cardboard of the utility model is increased. At the same time, since low-density fiber is a renewable resource, it can be recycled, which is more energy-saving and environmentally friendly.

[0022] 6. The wear-resistant layer of the utility model is made of high-density fiber. Since high-density fiber is a fiber material with high density and high strength, it is usually mixed with multiple synthetic fibers. It has good structural strength, wear resistance and corrosion resistance, thereby increasing the wear resistance, corrosion resistance and other excellent properties of the white cardboard of the utility model.

[0023] 7. The waterproof layer in the utility model is made of polyethylene waterproof board. By setting the polyethylene waterproof board, the waterproof performance of the white cardboard of the utility model is greatly increased. When the white cardboard is pressed, it is only necessary to place the polyethylene waterproof board between the white cardboards. Thus, the polyethylene waterproof board is heated to a molten state during hot pressing, which not only ensures the waterproof effect, but also increases the tightness of the pressed white cardboard.
