Production process of lightweight high-strength corrugated paper

Abstract

The invention discloses a production process of a light-weight high-strength corrugated paper, relates to the related field of corrugated paper production, and aims to solve the problems that the existing corrugated paper is insufficient in strength, and the strength of the corrugated paper is increased by adding a corrugated base paper layer, so that the light weight of the corrugated paper is influenced. The production process comprises the following steps: S1, soaking treatment, and then heating and cooking, S2, draining after cooling, crushing, primarily screening, grinding in a pulping machine, and screening again, S3, dividing of slurry into slurry A and slurry B, S4, preparation of mixed pulp A, papermaking, dehydrating and drying to prepare inner paper and surface paper, S5, preparation of mixed pulp B, papermaking, dehydrating and drying to prepare raw paper, S6, corrugating for forming a corrugated base paper, S7, cutting of an inner paper, two surface papers and two corrugated base papers, S8, preparation of an environment-friendly colloid, S9, sizing for fixing the corrugated base paper and the inner paper, S10, sizing for fixing the surface paper, S11, drying and thencooling, and S12, reinforcing agent spraying, and then drying.

Description

technical field [0001] The invention relates to the related field of corrugated paper production, in particular to a production process of lightweight high-strength corrugated paper. Background technique [0002] Corrugated cardboard began at the end of the 18th century, and its application increased significantly in the early 19th century because of its light weight, low price, wide range of uses, easy production, and the ability to be recycled or even reused. By the beginning of the 20th century, it had been fully popularized, promoted and applied for the production of packaging for various commodities. Since the packaging container made of corrugated cardboard has its unique properties and advantages for beautifying and protecting the goods inside, it has achieved great success in the competition with various packaging materials. It has become one of the main materials for making packaging containers that has been used for a long time and is developing rapidly. Corrugat...
