Abstract

The invention provides an adhesion agent, a preparation method thereof and a corrugated board. The adhesion agent is made of raw materials including, by weight, 1000 parts of water, 220-350 parts of starch, 6-12 parts of sodium hydroxide, 1-6 parts of moisture-resistant agent red glue, 1-4 parts of moisture-resistant agent white glue, 7-15 parts of bridging agents and 1-4 parts of sodium borate. The invention further provides a preparation method of the adhesion agent and a corrugated board prepared by the aid of the adhesion agent. The formula of the adhesion agent is improved, the moisture-resistant agent red glue and the moisture-resistant agent white glue are added into the starch, glue bodies of the moisture-resistant agent red glue and the moisture-resistant agent white glue has a lot of active groups, the active groups and starch hydroxide radical can three-dimensionally crosslink, so that a solidified glue layer is further hardened, and the performances such as hardness, bursting and edge pressing of the corrugated board are remarkably improved. In addition, the moisture-resistant agent red glue and the moisture-resistant agent white glue has high permeability, the active groups of the moisture-resistant agent red glue and the moisture-resistant agent white glue can instantaneously penetrates paper fiber gaps, contact angles among the adhesive layers and fibers are reduced, the permeability of glue is improved, and adhesive strength is improved.

Description

technical field [0001] The invention relates to the technical field of adhesives for packaging materials, in particular to an adhesive for corrugated cardboard, a preparation method thereof, and a corrugated cardboard produced by using the adhesive. Background technique [0002] Corrugated cartons are currently commonly used packaging and transportation containers, which are rigid paper containers made of corrugated cardboard. Corrugated cardboard is usually made by bonding carton board (or called face paper) and corrugated base paper (or called corrugated paper) with adhesive. The base material of container board and corrugated base paper is base paper. Due to the characteristics of the fiber structure of the base paper itself, corrugated cardboard is very sensitive to moisture, and it is easy to absorb water and get wet in complex environments such as rainy days, humidity, and high temperature. Once the corrugated box is damp, its strength will be greatly reduced (general...
