Embodiment Construction

[0023] The best embodiment of the present invention will be further described in detail below.

[0024] In an embodiment of the present invention, the processing method of the high-strength corrugated paper includes the following steps:

[0025] Step 1, preparing raw paper pulp;

[0026] Step 2, adding a strengthening agent to the base paper pulp;

[0027] Step 3, heat-treating the base paper;

[0028] Step 4, gluing the surface of the base paper;

[0029] Step 5, compounding base paper by a corrugating machine to obtain corrugated paper;

[0030] Step 6, cooling after drying to obtain high-strength corrugated paper.

[0031] The base paper pulp includes the following components by mass: 8 parts of crop straw, 5 parts of hickory wood, 8 parts of birch wood, 3 parts of pear wood, and 2 parts of iron knife wood.

[0032] The reinforcing agent includes 8-10 parts of polyamideimide, 2-4 parts of polyhydroxy chemical coupling agent, 3-5 parts of phosphite, 2-5 parts of ethylen...

Abstract

The invention discloses a high-strength corrugated paper processing method comprising the following step I of preparing base paper pulp; the step II of adding reinforcing agents to the base paper pulp; the step III of performing heat treatment to base paper; the step IV of performing sizing treatment to the surface of the base paper; the step V of compounding the base paper through a corrugating machine to obtain corrugated paper; the step VI of performing cooling treatment after drying to obtain the high-strength corrugated paper. According to the processing method, the burst index and the ring crush index of the corrugated paper are improved, so that the corrugated paper is higher in strength, and the service life of a corrugated box is prolonged; and the market use requirements are met,and the promotion of products is benefited.

Description

technical field [0001] The invention belongs to the technical field of corrugated paper processing, and in particular relates to a processing method of high-strength corrugated paper. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. The existing corrugated paper has low strength and cannot meet the needs of use. Contents of the invention [0003] The purpose of the present invention is to propose a processing method for high-strength corrugated paper, which overcomes the above-mentioned shortcomings of the prior art, and enhances the burst resistance index and ring pressure index of the corrugated paper, so that the corrugated paper has higher strength and improves the quality of corrugated boxes. The service life is long, which meets the market demand and is conducive to product promotion. [0004] In order to achieve the above-mentioned...
