Environment-friendly easily-decomposed corrugated paper and processing technology thereof

Abstract

The invention discloses environment-friendly easily-decomposed corrugated paper and a processing technology thereof.The environment-friendly easily-decomposed corrugated paper is prepared from 30-40 parts of straw pulp board, 100-120 parts of waste paper, 0.5-0.7 part of deinking agent, 0.12-0.2 part of retention aid, 1-3 parts of polyurethane, 4-7 parts of flame retardant and 5-10 parts of corn starch glue.The processing technology of the environment-friendly easily-decomposed corrugated paper comprises the following steps: 1, ingredient weighing; 2, deinking and crushing; 3, slurry desanding; 4, screening and deslagging; 5, residual slurry refluxing; 6, mixing and stirring; 7, slurry flowing treatment; 8, dehydrating to form paper; and 9, wet paper squeezing. According to the method, pulp residues are recycled into a high-concentration hydraulic crusher to be crushed and filtered to form accepted pulp, so that recycling of waste pulp residues is achieved; corrugated paper is bonded through corn starch glue, so that decomposition of the corrugated paper is facilitated; the corrugated paper is rapidly dried through a carton drying machine, so that the solidification time of the corn starch glue is shortened; and by adding a flame retardant agent, the flame retardant property of the corrugated paper is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated paper processing, in particular to an environmentally friendly and easily decomposable corrugated paper and a processing technology thereof. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board. [0003] Corrugated paper has the advantages of high structural strength, easy handling and low cost, so the application prospect of corrugated paper is very broad. At the same time, many companies are manufacturing corrugated paper. The rate is only about 40%, and a large amount of cellulose is discarded with the discharge of pulp residue and waste water, causing pollution and greatly increasing the cost. Moreover, the corrugated paper currently on the market has poor flame retardancy, and it is not suitable to extin...

Problems solved by technology

[0003] Corrugated paper has the advantages of high structural strength, easy handling and low cost, so the application prospect of corrugated paper is very broad. At the same time, many companies are manufacturing corrugated paper. The rate is only about 40%, and a large amount of cellulose is discarded along with the discharge of pulp residue and waste water, causing pollution and greatly increasing the cost. Moreover, the corrugated paper currently on the market has poor flame retardancy, and it is not suitable to extinguish when a fire occurs. It is very dangerous, and the corrugated paper solidifies slowly after being glued, which greatly reduces the work efficiency. At the same time, it is not easy to decompose after being discarded, causing a certain burden on the environment.
