Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paperboards, and in particular relates to an environmentally friendly corrugated paperboard with a heat-insulating structure. Background Art

[0002] With the continuous innovation of modern packaging technology, the requirements for packaging materials are becoming more and more stringent. As an advanced packaging material, aluminum foil insulation corrugated cardboard has aroused enthusiastic response in the market with its excellent performance and wide application fields. This material cleverly combines the characteristics of aluminum foil and corrugated cardboard. It not only inherits the excellent properties of aluminum foil such as moisture resistance, oxidation resistance and UV radiation resistance, but also has the physical properties of corrugated cardboard such as buffering, shock resistance, heat preservation and insulation.

[0003] However, the current structural design of aluminum foil corrugated cardboard still has some limitations. It is usually composed of an aluminum foil layer, an insulation cotton layer, a face paper, a corrugated core and a bottom paper. The aluminum foil layer and the insulation cotton layer are the key insulation structural layers, which are often directly attached to the outer layer of the face paper or bottom paper of the corrugated cardboard by composite bonding. Although this design achieves the insulation effect, it also leads to an increase in the overall thickness of the corrugated cardboard, thereby reducing its plasticity, making it more difficult to fold into a carton. In addition, this simple stacking design fails to fully explore and maximize the potential performance of the corrugated cardboard.

[0004] Therefore, it is very necessary to invent an environment-friendly corrugated paperboard with a heat-insulating structure. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an environmentally friendly corrugated paperboard with a thermal insulation structure, comprising face paper, bottom paper, an interlocking thermal insulation board, aluminum foil and a corrugated core, wherein the inner sides of the face paper and the bottom paper are both compositely bonded with the interlocking thermal insulation board; the outer surface of the face paper is compositely bonded with the aluminum foil; and the corrugated core is compositely bonded between two interlocking thermal insulation boards.

[0006] Preferably, the thickness of the face paper and the bottom paper are the same, the thickness of the aluminum foil is less than or equal to the thickness of the face paper and the bottom paper, and the surface of the corrugated cardboard where the aluminum foil is located is the heat-insulating surface.

[0007] Preferably, there are two interlocking insulation boards in total, and the two interlocking insulation boards have the same structure, both consisting of an aluminum foil base and an insulation body. The insulation body of the interlocking insulation board is an equilateral trapezoidal structure made of insulation cotton, and there is a spacing between the insulation bodies that allows them to have the same size.

[0008] Preferably, the corrugated core is an equilateral trapezoidal corrugated structure, and the thermal insulation body of the interlocking thermal insulation board is located inside the equilateral trapezoidal spacing formed by the corrugated core itself.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model abandons the method of simply compounding the entire insulation structure on the outside of the cardboard body in the traditional aluminum foil corrugated cardboard design, and instead adopts a design in which the insulation structure is cleverly set inside the cardboard. This design not only greatly improves the safety of the insulation structure, but also effectively controls the overall thickness of the cardboard, thereby significantly improving the plasticity of the aluminum foil corrugated cardboard. In addition, the adopted bite insulation board design is unique. Its equilateral trapezoidal insulation body structure not only minimizes the increase in overall thickness, but also enhances the bite effect with the corrugated core through its special shape design, thereby improving the bonding strength. This design cleverly makes full use of the gap area of ​​the corrugated core, realizes the close combination of the insulation structure and the cardboard body, and further enhances the overall performance and stability of the cardboard.

[0017] As attached Figure 1 To Attachment Figure 2 As shown:

[0018] The utility model provides an environmentally friendly corrugated paperboard with a heat preservation structure, comprising a face paper 1, a bottom paper 2, an interlocking heat preservation board 3, an aluminum foil 4 and a corrugated core 5. The inner sides of the face paper 1 and the bottom paper 2 are both compositely bonded with the interlocking heat preservation board 3; the outer surface of the face paper 1 is compositely bonded with the aluminum foil 4; and the corrugated core 5 is compositely bonded between the two interlocking heat preservation boards 3. The method of simply composite the entire heat preservation structure on the outside of the paperboard body in the traditional aluminum foil corrugated paperboard design is abandoned, and the design of cleverly setting the heat preservation structure inside the paperboard is adopted. This design not only greatly improves the safety of the heat preservation structure, but also effectively controls the overall thickness of the paperboard, thereby significantly improving the plasticity of the aluminum foil corrugated paperboard. Embodiment 1:

[0019] Specifically, the thickness of the face paper 1 and the bottom paper 2 are designed to be the same to ensure the structural stability of the paperboard in the longitudinal and transverse directions. In addition, the thickness of the aluminum foil 4 is carefully controlled to be less than or equal to the thickness of the face paper 1 and the bottom paper 2. Such a design not only ensures that the aluminum foil 4 can be closely attached to the outer surface of the face paper 1, but also ensures that the thickness of the entire paperboard is within an acceptable range and will not be significantly increased due to the addition of the aluminum foil 4.

[0020] Furthermore, the surface of the corrugated paperboard where the aluminum foil 4 is located is designed as a heat-insulating surface. This means that the aluminum foil 4 can effectively reflect and block external heat, providing an additional heat-insulating barrier for the inside of the paperboard. This design enables the corrugated paperboard to have excellent heat-insulating properties while maintaining lightness and plasticity, and is particularly suitable for packaging occasions that require heat-insulating effects. Embodiment 2:

[0021] Specifically, there are two interlocking insulation boards 3, and the structures of the two interlocking insulation boards 3 are exactly the same. Each interlocking insulation board 3 is composed of an aluminum foil base and an insulation body, achieving a perfect combination of function and structure. The insulation body of the interlocking insulation board 3 adopts an equilateral trapezoidal structure made of insulation cotton material. This equilateral trapezoidal design not only optimizes the layout of the insulation material, but also provides a good interlocking space for the corrugated core 5 through the gaps between the trapezoidal structures. The insulation bodies have a spacing that allows them to be of the same size. This design not only ensures the close connection between the insulation materials, but also provides sufficient space for the embedding of the corrugated core 5.

[0022] Furthermore, by arranging the interlocking insulation board 3 of the equilateral trapezoidal structure on the inner side of the face paper 1 and the bottom paper 2, and bonding them with the corrugated core 5, a close combination of the insulation structure and the paperboard body is achieved. This design not only enhances the insulation performance of the paperboard, but also improves its structural stability. At the same time, due to the spacing design between the insulation bodies, the corrugated core 5 can make full use of these gaps, further improving the compression resistance and buffering performance of the paperboard.

[0023] Specifically, the corrugated core 5 is an equilateral trapezoidal corrugated structure, and the heat-insulating body of the interlocking heat-insulating board 3 is located inside the equilateral trapezoidal spacing formed by the corrugated core 5. This layout enables the heat-insulating body to fully utilize the gap area of ​​the corrugated core 5, which not only realizes the effective use of the heat-insulating material, but also enhances the overall connection strength between the heat-insulating structure and the paperboard body.

[0024] Through this design, the utility model optimizes the overall structure of the paperboard while ensuring the thermal insulation performance of the paperboard. The corrugated core 5 of the equilateral trapezoidal flute structure and the equilateral trapezoidal thermal insulation body of the interlocking thermal insulation board 3 interlock with each other to form a stable and tight thermal insulation layer. This thermal insulation layer can not only effectively isolate the heat transfer from the outside, but also provide additional protection for the packaged items.

[0025] In addition, this design also makes the cardboard easier to operate when folding and forming, improving production efficiency and product quality. At the same time, due to the rational use of insulation materials and the optimization of cardboard structure.

[0026] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
