Abstract

The invention provides a method for preparing high-strength corrugated base paper, comprising: mixing 30-50 parts by weight of national waste paper, 10-30 parts by weight of Japanese OCC waste paper, and 40-60 parts by weight of European waste OCC and / or British OCC waste paper mixed pulping to obtain OCC waste paper mixed pulp; the national waste paper is grade A and / or B grade; the OCC waste paper mixed pulp is mixed with broke pulp, after slag removal, Papermaking and sizing are carried out to obtain high-strength corrugated base paper; the mass ratio of the mixed OCC waste paper to broke pulp is (80-90): (10-20). Compared with the prior art, the present invention uses Japanese OCC waste paper, European OCC waste paper and British OCC waste paper as raw materials. These waste papers are paper produced from primary wood pulp, and the fiber length and strength are retained. The fibers in the waste paper pulp are miscellaneous. The content of cells and impurities is low, which is beneficial to avoid shrinkage of fiber paper and improve the bonding strength of paper.

Description

technical field

[0001] The invention belongs to the technical field of papermaking, in particular to a method for preparing high-strength corrugated base paper. Background technique

[0002] Corrugated base paper is one of the important constituent materials for the production of corrugated cardboard. Corrugated base paper requires good fiber bonding strength, smooth paper surface, good tightness and stiffness, and requires a certain degree of elasticity to ensure that the made carton has shock resistance and pressure resistance.

[0003] In the current paper industry, most enterprises use secondary fibers to produce corrugated base paper, which not only has low raw material and production costs, but also is environmentally friendly. However, domestic secondary fiber corrugated base paper manufacturers mainly using waste paper raw materials are unable to provide products with low shrinkage, good paper strength and stable performance to packaging and printing companies due t...
