Description
Technical Field
The invention relates to a preparation method of high-strength corrugated paper, and belongs to the technical field of preparation of packaging paper.
Background
Corrugated paper, also known as kraft paper and leatheroid, is a common material for paper packing boxes, is lighter than wood boxes, has hardness, is easy to cut in size, and is used for protecting other packaged products from being damaged. The corrugated paper can be printed with patterns and characters of different colors or written with characters and symbols on the outside, and the cost is relatively low. Medium and small corrugated paper boxes (without any printing and mud yellow) can be purchased in daily product stores. However, the corrugated paper is not soaked in water, moist, moldy, soaked in water, hooked by hands, etc. Corrugated paper is sometimes used as handicraft material, corrugated paper specially used for handicraft has various color choices, and people also manufacture paper furniture with the corrugated paper. At present, the most commonly used corrugated board is formed by gluing brown paper, boxboard paper, white board paper and other corn starch glue, and is a full-paper corrugated board; the calcium plastic corrugated board is also formed by bonding calcium plastic paper in a hot melting mode. Both have respective advantages and disadvantages, and are widely applied in the field of packaging. Corrugated paper is generally made from broad-leaved semi-fibrous wood pulp or wheat straw pulp, etc., and its basis weight is generally low, but corrugated paper functions as a skeleton in corrugated board after being formed at a certain temperature and pressure. In the process of making corrugated paper, it is common to employ: the process design of pulping → pressure pump sending to stable pulp pool → water pressure difference water spraying and pulp hanging → felt penetrating and absorbing → vacuum pump dewatering and drying → drying by heating dryer → finished product shaping and rolling and cutting, the process defect is that the surface is sometimes for saving cost, pulping is carried out after waste paper is crushed by water wetting, but the water resistance and puncture resistance are reduced, and the strength and moisture content of the corrugated paper finished product are influenced because the drying and curing process on the preparation process is shorter.
Corrugated paper is a plate-like object formed by bonding liner paper and corrugated paper formed by processing with a corrugated roller, and is generally divided into single corrugated paper board and double corrugated paper board, and the corrugated paper has the advantages of low cost, light weight, easy processing, excellent printing adaptability, convenient storage and transportation, and the like. At present, the corrugated paper on the market can not carry out effectual fire-retardant and fire prevention, and in the external environment, the corrugated paper is very easy to take place phenomenons such as fire or spontaneous combustion because of the unexpected condition again, especially in the environment that the corrugated paper is in the high temperature, has very big corrugated paper burning phenomenon that probably appears, the safety in utilization of great increase corrugated paper, is unfavorable for the user to the use of corrugated paper.
The corrugated case can be folded, so that the occupied space is small during storage and transportation, and the corrugated case is convenient to store and transport and cannot be used for wood packaging and metal packaging. The single-layer corrugated board has certain strength, but if the single-layer corrugated board is used as a bookcase, a chair, a sofa and the like, the supporting force is insufficient, the strength of the double-layer corrugated board and the three-layer corrugated board is increased, and the occupied space is increased greatly. In addition, most of the core boards of the corrugated boards in the prior art are V-shaped or U-shaped, and the strength is relatively common due to the defects of the structures.
The existing corrugated paper soybean has the problems of low mechanical strength and tear resistance, so the invention of the high-strength corrugated paper has positive significance in the technical field of packaging paper products.
