Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with specific examples. The following examples and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0020] A high-strength corrugated cardboard production process, comprising the following steps, step 1: glue making, the glue making process is as follows: a, first add 350kg water and 35kg starch successively in the glue making bucket A barrel, fully stir with 400 rpm / min for 30 Minutes, then dilute the weighed 10kg of alkali with 15kg of water and add it to barrel A, and stir it fully for 30 minutes at 400 rpm; Stir fully for 30 minutes, then add 10kg of resin adhesive, stir fully at 450 rpm for 30 minutes, and finally pour the glue in barrel A into barrel B and stir to form a slurry; c. Put it into the glue making barrel B barrel Add 5.5kg of borax, and fully stir it into glue at 450 rpm; step 2, the corrugated base paper is passed t...

Abstract

The invention specifically relates to a production process for a high-strength corrugated board, belonging to the field of processing of paperboards. The production process comprises the following steps: preparing glue, allowing a corrugated medium to pass through a fixed guide roller and a swinging guide roller, gluing the corrugated medium with a glue spreader so as to obtain a first corrugated layer and bonding the first corrugated layer with a first surface paper layer so as to obtain a first single-side single-arch corrugated board; allowing the corrugated medium to pass through the fixed guide roller and the swinging guide roller, gluing the corrugated medium with the glue spreader so as to obtain a second corrugated layer and bonding the second corrugated layer with a second surface paper layer so as to obtain a second single-side single-arch corrugated board; allowing the corrugated medium to pass through the fixed guide roller and the swinging guide roller, gluing the corrugated medium with the glue spreader so as to obtain a third corrugated layer and bonding the third corrugated layer with a third surface paper layer and a fourth surface paper layer so as to obtain a third double-side single-arch corrugated board; and bonding the first single-side single-arch corrugated board, the second single-side single-arch corrugated board and the third double-side single-arch corrugated board and then carrying out heating and curing on the bonded corrugated boards in a vacuum curing channel. The production process improves product quality and reduces energy consumption and environmental pollution.

Description

technical field [0001] The invention relates to the field of cardboard processing, in particular to a high-strength corrugated cardboard production process. Background technique [0002] At present, packaging cartons are the most widely used products in the packaging industry. The production of corrugated cardboard used in my country is made of corrugated paper that is processed into waves by corrugating rollers. In order to improve the value of packaging cartons, people have been researching and Improve, reduce cost, increase strength, facilitate production, improve the efficiency of automatic production, so that it can be produced on the automatic production line of multi-layer corrugated cardboard forming machine with a high degree of automation. [0003] In the prior art, in order to increase the strength of the packaging cardboard, generally by increasing the weight of the cardboard, that is, increasing the quality of the raw paper, or increasing the number of layers of ...
