Description

Technical Field

[0001] The invention belongs to the field of corrugated paperboard, and in particular relates to a corrugated paperboard and a processing system for producing and processing the corrugated paperboard. Background Art

[0002] As a common packaging material, corrugated cardboard is widely used in the packaging, transportation and storage of various products due to its advantages such as light weight, low cost, high structural strength and easy processing. Especially in the context of the rapid development of logistics and e-commerce, the demand for corrugated cardboard continues to grow. However, the physical properties and structural stability of traditional corrugated cardboard will be significantly affected when facing a humid environment or liquid contact. The penetration of water will cause the strength of the corrugated cardboard to decrease, deform or even disintegrate, thus affecting its packaging and protection functions. In order to overcome the above problems, the market demand for corrugated cardboard with waterproof properties is increasing. Waterproof corrugated cardboard can not only effectively prevent moisture penetration, but also maintain its original physical properties and structural stability, thereby providing more reliable packaging and protection in a humid environment.

[0003] The existing method of applying the waterproof layer of corrugated cardboard generally adopts the coating method to apply the single-sided coating on the corrugated cardboard. This traditional waterproof method can only protect the corrugated cardboard from one side, and there is no redundant waterproof structure inside the corrugated cardboard, which is very easy to wet the base paper, thereby causing the entire corrugated cardboard to deform. At the same time, during the coating process, the waterproof material is easy to solidify due to temperature changes or long-term exposure to the air, resulting in reduced material fluidity and affecting the continuity and uniformity of the coating; and because the waterproof material may precipitate or stratify during storage and transportation, the material concentration is uneven during coating, which in turn affects the stability of the waterproof effect. Summary of the invention

[0004] The purpose of the present invention is to provide a corrugated paperboard. Through the effect of a desiccant, the desiccant is pasted and fixed in the gap of the vertical corrugated paper core. This protective film can effectively prevent moisture from penetrating through the gap of the corrugated paperboard, thereby providing more comprehensive waterproof protection. Filling the desiccant in the gap of the vertical corrugated paper core can seal the tiny gap inside it, prevent moisture from entering the inside of the paperboard through these weak links and wetting the base paper, and solve the problem that the existing waterproof layer coating method of the corrugated paperboard generally adopts a coating method to coat the corrugated paperboard on one side. This traditional waterproof method can only protect the corrugated paperboard from one side, and there is no redundant waterproof structure inside the corrugated paperboard, which is very easy to wet the base paper, thereby causing the entire corrugated paperboard to deform.

[0037] The present invention has the following beneficial effects:

[0038] 1. The present invention uses the effect of desiccant to fix desiccant in the gap of vertical corrugated paper core by sticking it. Silicone emulsion, emulsified paraffin, emulsified polyethylene wax desiccant can absorb moisture to prevent moisture from penetrating into the vertical corrugated paper core. At the same time, silicone emulsion and other materials will form a hydrophobic protective film after drying. This protective film can effectively prevent moisture from penetrating through the gap of vertical corrugated paper core, thereby providing more comprehensive waterproof protection. Filling it in the gap of vertical corrugated paper core can seal the tiny gap inside it, preventing moisture from entering the inside of the paperboard through these weak links and wetting the base paper.

[0039] 2. The present invention uses the function of the stirring box to keep the material in a dynamic flow state through stirring, thereby reducing the risk of solidification and ensuring the continuity of coating. If the waterproof material solidifies, the coating will be interrupted, affecting the production efficiency. The stirring function of the stirring box can effectively avoid such a situation. The waterproof coating evenly stirred by the stirring box can be more evenly covered on the surface of the corrugated cardboard during coating. The material has stable fluidity and uniform concentration, so that the quality of the waterproof layer after coating is better, which can effectively prevent moisture penetration, maintain the physical properties and structural stability of the corrugated cardboard, and enhance the packaging and protection functions of the product.

[0040] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
