Abstract

The invention belongs to the technical field of carton manufacturing, and in particular relates to a moisture-proof and pressure-resistant carton and a preparation method thereof. The moisture-proof and pressure-resistant carton provided by the present invention is made of moisture-proof and pressure-resistant cardboard, and the moisture-proof and pressure-resistant cardboard is made by alternately pasting n layers of corrugated core paper and n+1 layers of flat sheet paper. The moisture-proof and pressure-resistant carton provided by the invention has a hydrophobic solid paraffin film layer on the surface of the cardboard, which can effectively prevent the intrusion of water vapor on the carton in a humid environment, thereby maintaining high rigidity and strong compression resistance in a humid environment . When making cardboard, the present invention adds pre-supported nano-composite particles into the pulp and cooperates with the method of pulling the coating film, and realizes that the corrugated cardboard is pasted first and then coated with a waterproof film, thereby skillfully avoiding the occurrence of the waterproof coating on the adhesion strength of the corrugated cardboard adverse effects. In addition, the present invention also found that dispersing the pre-supported nanocomposite particles in the pulp can effectively inhibit the bending deformation of the paperboard.

Description

technical field [0001] The invention belongs to the technical field of carton manufacturing, and in particular relates to a moisture-proof and pressure-resistant carton and a preparation method thereof. Background technique [0002] Corrugated box is the most widely used packaging product, and its consumption has always been the first among all kinds of packaging products. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting goods and facilitating storage and transportation, corrugated boxes also play a role in beautifying and promoting goods. [0003] However, corrugated boxes are paper products, and paper products contain a large amount of chain molecules with hydrophilic hydroxyl groups on the surface, such as cellulose and lignin, which makes c...
