[0003] At present, the adhesives for corrugated cardboard mainly used in my country usually use starch as raw material. Although starch adhesives have a wide range of sources, rich content, non-toxic, non-polluting, and low cost, they are greatly affected by temperature and composition. Unstable, and the drying temperature is too high during use, which cannot meet the needs of high-speed production. It is prone to precipitation, poor permeability, and sometimes false sticking, foaming, and degumming, resulting in low productivity, high production costs, and poor product quality. Stability and other issues

Abstract
The invention provides a corrugated board with high stability and high strength and a production process of the corrugated board. The production process comprises the following steps: a, selecting paper-plastic waste paper as a raw material for manufacturing the corrugated board; b, pulping the paper-plastic waste paper, and screening, purifying and pulping the pulp, so that the ash content of the pulp is less than 5%, and the fiber beating degree is 30-45 degrees SR; c, adding cationic rosin size, aluminum sulfate and a wet strength agent into the slurry, and uniformly mixing; d, forming, dehydrating, squeezing and drying to obtain a semi-finished corrugated board; e, carrying out surface sizing treatment on the semi-finished product paper, wherein a glue solution for sizing is low-temperature corrugated board glue; and f, drying to obtain a finished product corrugated board. According to the corrugated board disclosed by the invention, the use amount of heating steam can be reduced in the processing and bonding process, when the corrugated boards in one batch are bonded, the amount of steam is reduced from 8-9 kilograms to 5 kilograms or below, the heating procedure is reduced, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of packaging materials, in particular to a corrugated cardboard with good stability and high strength and a production process thereof. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated cardboard and one layer of cardboard paper, which has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. [0003] At present, the adhesives for corrugated cardboard mainly used in my country usually use starch as raw material. Although starch adhesives are widely sourced, rich in content, non-toxic, non-polluting, and low in cost, they are greatly affected by temperature and composition. Unstable, and the drying temperature is too high during use, which cannot meet the needs of high-speed production. It is prone to precipitation, poor permea...
