Embodiment 1

[0025] Example 1 Preparation of high-strength corrugated base paper

[0026] Raw materials: 90% of national waste, 10% of pulp residue

[0027] Put the waste paper into the hydraulic pulper to disintegrate. After the disintegration, the slag is removed by the high-concentration desander and then enters the classifying screen. It is classified into two kinds of fibers: long fiber and short fiber. The classification ratio of long fiber and short fiber is 5 :5. The long fibers are processed by four-stage heavy desander, three-stage fine screen, and two-stage light desander. After being concentrated by multiple discs, they are sent to double disc mills for beating to make long fiber slurry with a beating degree of 35°SR; After being treated by three-stage heavy desander and light desander, short fiber slurry is made after multi-disk concentration;

Embodiment 2

[0030] Example 2 Preparation of high-strength corrugated base paper

[0031] Raw materials: 40% of national waste, 60% of pulp residue

[0032] Put the waste paper into the hydraulic pulper to disintegrate. After the disintegration, the slag is removed by the high-concentration desander and then enters the classifying screen. It is classified into two kinds of fibers: long fiber and short fiber. The classification ratio of long fiber and short fiber is 5 :5. Long fibers are processed by four-stage heavy desander, three-stage fine screen, and two-stage light desander. After being concentrated by multiple discs, they are sent to double disc mills for beating to make long fiber slurry with a beating degree of 32°SR; After being treated by three-stage heavy desander and light desander, short fiber slurry is made after multi-disk concentration;

Abstract

The invention relates to a renewable high-strength corrugated medium and its manufacturing method. The raw paper is prepared from 40-90% of old paper stock and 10-60% of dreg paper pulp. The invention also provides a high-strength corrugated paper and its production method. The right side and back side of the corrugated medium are respectively provided with sizing layers. According to the renewable high-strength corrugated medium, waste paper and dregs are used as raw materials. Therefore, the renewable high-strength corrugated medium has good environmental protection property and requires low papermaking cost. According to the renewable high-strength corrugated paper, the raw paper layer is prepared from waste paper and dregs which are used as raw materials. The right side and the back side are both provided with the sizing layers. The production method requires low papermaking cost and is beneficial to environmental protection. Key technical indexes of the production method all reach national standard (GB / T13023-2008) superior product AA grade.

Description

technical field [0001] The invention relates to a recycled high-strength corrugated base paper and a production method thereof, belonging to the technical field of pulping and papermaking. Background technique [0002] The high-strength corrugated base paper currently produced in the market mainly uses waste paper pulp as the main raw material, with a part of wheat straw pulp or cotton straw pulp or chemical mechanical thermal refining (CTMP) as auxiliary raw materials. At the present stage, straw pulp pulping not only causes serious pollution, but also easily pollutes the environment, and the cost of wastewater treatment is high, so its use is limited; cotton straw pulp and chemical mechanical thermal refining, due to their high cost, are generally used to make high-quality pulp. High-strength paper, such as banknote paper, coated paper, etc.; in the actual situation of low domestic forest coverage, wood pulp generally relies on imports. If it is used to make high-strength ...
