Description

Technical Field

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

[0002] Cardboard has a light weight and good protection for the packaged goods, and is mostly used in the packaging field. Compared with wooden boards, cardboard has a lower cost, which is beneficial to reducing the costs of product packaging and logistics.

[0003] In the field of cardboard for packaging, corrugated cardboard is often used. The corrugated cardboard has good air permeability in the plane direction inside, which is beneficial to avoiding the problem of internal mildew, but it has almost no mildew-proof and antibacterial effects on the surface. In addition, in places with high humidity, the inside of the corrugated cardboard is likely to introduce moisture due to air permeability, which not only easily reduces the structural strength, but also breeds bacteria and causes mildew, and thus needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mildew-proof and antibacterial composite cardboard, which improves the internal and external mildew-proof and antibacterial effects and ensures the structural strength.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A mildew-proof and antibacterial composite cardboard, comprising: a surface layer paper, a bottom layer paper, corrugated paper and a mildew-proof filling member. The surface layer paper is arranged above the corrugated paper, the bottom layer paper is arranged below the corrugated paper. A first waterproof film layer is arranged on the top surface of the surface layer paper, and an antibacterial coating is arranged on the top surface of the first waterproof film layer. Arc-shaped grooves are arranged at intervals on the top surface of the corrugated paper. The mildew-proof filling member is arranged in some of the arc-shaped grooves. The mildew-proof filling member includes a fixing strip, a support sheet and moisture-absorbing particles. The fixing strip is located at the top of the corresponding arc-shaped groove. The support sheets are arranged at intervals at the bottom of the fixing strip. An isolation chamber is formed between two adjacent support sheets. The moisture-absorbing particles are arranged in the isolation chamber. A plurality of ventilation holes are arranged on the support sheet.

[0007] Wherein, a second waterproof film layer is arranged on the bottom surface of the bottom layer paper.

[0008] Wherein, the surface layer paper and the bottom layer paper are respectively made of kraft paper.

[0009] Wherein, the fixing strip and the support sheet adopt an integrated plastic structure.

[0010] Wherein, the moisture-absorbing particles adopt calcium chloride moisture-absorbing particles, and the particle size of the moisture-absorbing particles is larger than the diameter of the ventilation holes.

[0011] Wherein, a first waterproof adhesive layer for bonding with the top of the corrugated paper and the fixing strip is arranged on the bottom surface of the surface layer paper.

[0012] Wherein, a second waterproof adhesive layer for bonding with the bottom of the corrugated paper is provided on the top surface of the bottom paper.

[0013] The beneficial effects of the present utility model: A mildew-proof and antibacterial composite cardboard uses the first waterproof film layer to waterproof the surface paper, strengthens the surface antibacterial performance through the antibacterial coating, and fills the arc-shaped grooves through the mildew-proof filler. It can not only improve the compressive performance of the corrugated paper, but also conduct internal moisture absorption and mildew prevention, reducing the growth of bacteria. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a schematic structural diagram of the present utility model;

[0015] Figure 2 is Figure 1 the left view of the fixing strip and the support piece in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following combines Figures 1 to 2 and further illustrates the technical solutions of the present utility model through specific embodiments.

[0017] As Figure 1 shown, the mildew-proof and antibacterial composite cardboard includes: a surface paper 1, a bottom paper 2, a corrugated paper 3 and a mildew-proof filler. The surface paper 1 is arranged above the corrugated paper 3, the bottom paper 2 is arranged below the corrugated paper 3, and a first waterproof film layer 8 is provided on the top surface of the surface paper 1. The first waterproof film layer 8 is used to waterproof the surface paper 1 and improve the structural strength of the surface paper 1.

[0018] An antibacterial coating 9 is provided on the top surface of the first waterproof film layer 8. The antibacterial coating 9 can adopt a silver ion antibacterial coating to improve the antibacterial effect of the surface layer. In addition, a second waterproof film layer 11 is provided on the bottom surface of the bottom paper 2. The second waterproof film layer 11 is used to waterproof the bottom surface of the bottom paper 2 to avoid the mildew problem of the bottom paper 2.

[0019] Arc-shaped grooves 12 are arranged at intervals on the top surface of the corrugated paper 3, which can improve the overall elastic buffering effect of the composite cardboard and increase the protection of the packaged object. The mildew-proof filler is arranged in some of the arc-shaped grooves for structural enhancement and moisture absorption and mildew prevention protection.

[0020] In this embodiment, the mildew-proof filler includes a fixing strip 4, a support piece 5 and moisture-absorbing particles. The fixing strip 4 is located at the top of the corresponding arc-shaped groove 12 to cover the corresponding arc-shaped groove 12. The support pieces 5 are arranged at intervals at the bottom of the fixing strip 4. As Figure 2 shown, the support piece 5 is perpendicular to the fixing strip 4, and an isolation chamber is formed between two adjacent support pieces 5. The moisture-absorbing particles are arranged in the isolation chamber, which can absorb the moisture entering the corrugated paper 3, improve the mildew-proof effect and reduce the growth of bacteria.

[0021] As Figure 1 shown, a plurality of ventilation holes 6 are provided on the support sheet 5 to increase the air circulation inside and outside the composite cardboard. In this embodiment, the moisture-absorbing particles are calcium chloride moisture-absorbing particles, which have good moisture-absorbing effect, and the particle size of the moisture-absorbing particles is larger than the diameter of the ventilation holes 6, which can not only allow air circulation but also prevent the escape of the moisture-absorbing particles.

[0022] In this embodiment, the fixing strip 4 and the support sheet 5 adopt an integrated plastic structure, which is convenient for injection molding production and has a stable structure. The shape of the support sheet 5 corresponds to the cross-section of the arc-shaped groove 12, which improves the compressive performance of the corrugated paper 3 and the overall structural strength, and can rebound after being compressed and deformed.

[0023] As Figure 1 shown, a first waterproof adhesive layer 7 for bonding with the top of the corrugated paper 3 and the fixing strip 4 is provided on the bottom surface of the surface paper 1 to prevent detachment. In this embodiment, the surface paper 1 and the bottom paper 2 are respectively made of kraft paper, which has high tear resistance and a stable structure. A second waterproof adhesive layer 10 for bonding with the bottom of the corrugated paper 3 is provided on the top surface of the bottom paper 2 to achieve multi-layer lamination.

[0024] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
