Abstract

The invention discloses a production process for a high-strength corrugated paperboard. The production process comprises the following steps: selecting raw materials; crushing the raw materials so asto prepare a raw paper pulp; adding a reinforcing agent into the raw paper pulp; preparing raw paper through a papermaking machine; subjecting the raw paper to heat treatment; subjecting the surface of the raw paper to sizing treatment; compounding the raw paper through a corrugating machine so as to prepare a corrugated paperboard; and carrying out drying and cooling treatment so as to obtain thehigh-strength corrugated paperboard. The corrugated paperboard prepared by using the corrugated paperboard production process provided by the invention has high strength and long service life, meetsuse requirements, has reasonable process design, low material consumption and low production cost, and can be extensively applied to the field of production of corrugated paper packing boxes.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a production process of high-strength corrugated cardboard. Background technique [0002] The use of corrugated cardboard can be traced back to the end of the 18th century. In the 19th century, people discovered that corrugated cardboard is not only light in weight but strong in performance, but also cheaper than ordinary materials, and has a simple manufacturing process and a wider range of uses. Not only that, corrugated cardboard is not only a recyclable and environmentally friendly material composed of wood fibers that can be decomposed by natural functions, but also can be reused without affecting its performance. Therefore, it is favored by people. [0003] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand b...
