Abstract

The invention discloses a wear-resistant high-strength corrugated cardboard and a preparation method thereof. The corrugated cardboard is composed of an upper paper, a V-shaped corrugated core and a lower paper; The protective layer on the side is composed of; the corrugated core base layer is composed of 100 parts of red pine wood pulp, 30-50 parts of bamboo wood pulp, 20-30 parts of fluff pulp, 40-60 parts of waste paper pulp, 1-5 parts of cyclodextrin, 10- 15 parts of oxidized tapioca starch, 4-8 parts of composite reinforcing fiber, 1-3 parts of cationic polyacrylamide, 0.01-0.1 part of sodium sorbate, 0.1-0.3 part of antimony trioxide, 0.1-0.5 part of polyvinyl alcohol, 5- 7 parts of polydimethylsiloxane; the protective layer is composed of 40-60% hydroxylated graphene modified polyacrylate emulsion, 5-10% sodium caseinate, 20-30% cationic rosin gum, 15-60% Composition of 20% microcrystalline kaolinite. The corrugated cardboard of the invention has high mechanical strength, excellent wear resistance, shock resistance, waterproof and moisture resistance, certain antibacterial and antifungal effects, simple preparation process, convenient operation and no need for repeated gluing.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a wear-resistant high-strength corrugated cardboard and a preparation method thereof. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated corrugated core paper and one layer of cardboard. It has good elasticity and extensibility, and can withstand collisions and falls during handling. It is mainly used for Outer packaging of fruits and vegetables, home appliances, and fragile goods. In the prior art, corrugated paper is mainly made of fiber raw materials. When used in a high-humidity environment for a long time, it is easy to absorb moisture and absorb moisture, resulting in a significant reduction in the mechanical strength and shock resistance of the paper. By coating the surface of the corrugated paper with a waterproof coating It can improve its waterproof and moisture r...
