Embodiment 1

[0024] A high-strength waterproof corrugated cardboard production process and its application in cartons, wherein the corrugated cardboard preparation process includes the following steps.

[0025] S1: Use a heater to heat the base paper. The base paper roll is placed on the feeder, and the paper is transported from the feeder to the heating roller. During the transportation, the heating roller is used to heat the paper to soften the paper and facilitate subsequent processing. The heating temperature is 55°C.

[0026] S2: embossing the heated base paper with corrugating rollers to form corrugated corrugated paper.

[0027] S3: Using modified corn starch glue to paste flat corrugated paper and corrugated corrugated paper to obtain two layers of corrugated paper. Modified cornstarch glue is ready-to-use glue. Take commercially available cornstarch glue and add 4% bis[3-diphenylphosphinomethyl-4-methoxy] to the cornstarch glue before use. Base-1-naphthyl]methane copper perchlo...

Embodiment 2

[0032] A high-strength waterproof corrugated cardboard production process and its application in cartons, wherein the corrugated cardboard preparation process includes the following steps.

[0033] S1: Use a heater to heat the base paper. The base paper roll is placed on the feeder, and the paper is transported from the feeder to the heating roller. During the transportation, the heating roller is used to heat the paper to soften the paper and facilitate subsequent processing. The heating temperature is 55°C.

[0034] S2: embossing the heated base paper with corrugating rollers to form corrugated corrugated paper.

[0035] S3: Using modified corn starch glue to paste flat corrugated paper and corrugated corrugated paper to obtain two layers of corrugated paper. The modified cornstarch glue is the glue that is ready to use. Take the commercially available cornstarch glue. The cornstarch glue is mixed with sodium hydroxide. Before use, add 3% bis[3-bis Phenylphosphinomethyl-4...

Abstract

The invention relates to the technical field of paper board processing, in particular to a production process for high-strength waterproof corrugated boards and application of the corrugated boards tocartons. The corrugated boards produced by the process have good waterproofness and high strength. The production process includes the steps that S1, raw paper is heated by a heater; S2, the heated raw paper is subjected to embossing treatment by utilizing corrugated rollers so as to form wavy corrugated paper; S3, modified corn starch glue is used for pasting flat corrugated paper to the wavy corrugated paper so as to obtain two-layer corrugated paper; S4, the modified corn starch glue is used for pasting two pieces of two-layer corrugated paper obtained in the step S3 so as to obtain four-layer corrugated boards; S4', the side walls of the corrugated boards are coated with the modified corn starch glue.

Description

technical field [0001] The invention belongs to the technical field of cardboard processing, in particular to a high-strength waterproof corrugated cardboard production process and its application in cartons. Background technique [0002] Packaging cartons are the most widely used products in the packaging industry. The production of corrugated cardboard used in my country is made by bonding corrugated paper processed into waves by corrugating rollers. In order to increase the value of packaging cartons, people have been researching and improving on packaging cartons to reduce costs, increase strength, facilitate production, and improve the efficiency of automated production, so that they can be used on the automatic production line of multi-layer corrugated cardboard forming machines with a high degree of automation. in production. [0003] In the prior art, in order to increase the strength of the packaging cardboard, generally by increasing the weight of the cardboard, t...
