[0002] Black cardboard refers to black cardboard paper, which is mainly divided into all-wood-pulp black cardboard and environmentally friendly black cardboard. Due to its special texture and feel, it is widely used in life.

[0003] Traditional black cardboard usually obtains black by dyeing, but this method often leads to problems such as rough surface and low gloss of the cardboard, and it is easy to fade during the printing process, affecting the printing quality and visual effect; to solve the above problems, a high-brightness black cardboard is proposed in this application. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a high-brightness black cardboard is proposed. By setting a base layer, a filler layer, a super-black curing layer, a calendering layer and a coating layer, the surface of the cardboard can be smooth and shiny, and the black color is not easy to fade, and the printing quality and visual effect are good.

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

[0006] A high-brightness black cardboard, including a black cardboard body, through holes are penetrated on the black cardboard body, text areas are provided on both the front and back of the black cardboard body, and the material of the black cardboard body is sequentially set as a base layer, a filler layer, a super-black curing layer, a calendering layer and a coating layer from the inside to the outside.

[0007] Preferably, the material of the base layer is a wood pulp paper layer.

[0008] Preferably, the material of the filler layer is a titanium dioxide layer.

[0009] Preferably, the material of the super-black curing layer is carbon black pigment.

[0010] Preferably, the material of the calendering layer is a polyurethane layer.

[0011] Preferably, the material of the coating layer is a dirt-proofing agent coating.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting a base layer, a filler layer, a super-black curing layer, a calendering layer and a coating layer, the surface of the cardboard can be smooth and shiny, and the black color is not easy to fade, and the printing quality and visual effect are good.

[0014] In summary, by setting the base layer, the filler layer, the super black curing layer, the calendering layer and the coating layer, the surface of the cardboard can be made smooth and shiny, and the black color is not easy to fade, with good printing quality and visual effect. Description of the Drawings

[0015] Figure 1 It is a schematic structural diagram of a high-brightness black cardboard proposed by the present utility model;

[0016] Figure 2 It is a cross-sectional view of a high-brightness black cardboard proposed by the present utility model.

[0017] In the figure: 1 black cardboard body, 2 through holes, 3 text area, 4 base layer, 5 filler layer, 6 super black curing layer, 7 calendering layer, 8 coating layer. Detailed Embodiment

[0018] 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 of the embodiments.

[0019] Refer to Figure 1 - Figure 2 , a high-brightness black cardboard, including a black cardboard body 1, through holes 2 are penetrated on the black cardboard body 1, and the black cardboard body 1 can be carried around by threading a rope through it. Text areas 3 are provided on both the front and back of the black cardboard body 1, and relevant information can be engraved on it.

[0020] The material of the black cardboard body 1 is sequentially set as a base layer 4, a filler layer 5, a super black curing layer 6, a calendering layer 7 and a coating layer 8 from the inside to the outside. The material of the base layer 4 is a wood pulp paper layer, and the wood pulp paper layer has the characteristics of environmental protection and recyclability, and at the same time has the characteristics of perfect smoothness, flatness and strong tensile strength; the material of the filler layer 5 is a titanium dioxide layer, and the titanium dioxide layer can improve the covering power and light reflectivity of the paper, making the black color of the black cardboard look deeper and more shiny; the material of the super black curing layer 6 is carbon black pigment, and the carbon black pigment has good coloring power and covering power, and low cost, and the carbon black pigment is quickly dried and cured by ultraviolet rays; the material of the calendering layer 7 is a polyurethane layer, and the polyurethane layer can form an isolation layer to prevent direct contact between water and the paper, and the surface is flattened by a calender; the material of the coating layer 8 is a dirt-proof coating, which can prevent the paper surface from getting dirty.

[0021] The production and processing steps of the black cardboard are as follows:

[0022] S1: Pulping, using equipment such as a disk refiner to mechanically process the pulp to improve the dispersion of fibers and the uniformity of the paper;

[0023] S2: Pressing, using a variety of press rolls to press the paper step by step to ensure uniform distribution of moisture and tension;

[0024] S3: Drying, using the technology that combines microwave heating and hot air to quickly evaporate the moisture in the paper while maintaining the flatness of the paper;

[0025] S4: Winding and rewinding, preliminarily collecting the dried paper through a winder to form large rolls of paper, and performing re-rewinding as needed to ensure the neatness of the paper and facilitate subsequent processing;

[0026] S5: Automatic paper cutting, using a numerically controlled automatic paper cutter to accurately cut according to the dimensions required by the customer to ensure the consistency of the paper specifications;

[0027] S6: Quality inspection, strictly inspecting the quality of the finished products, including multiple indicators such as blackness, smoothness, and physical strength, to ensure that each piece of black cardboard meets the predetermined standards.
