Production process of waterproof corrugated paperboard

Abstract

The invention relates to the technical field of paperboard processing, in particular to a production process of a double-faced waterproof corrugated paperboard. The production process comprises the steps that firstly, glue is prepared; secondly, body paper is preheated, and the preheated body paper is attached to a single facer for production after passing through a paper guide roller from a paper support; thirdly, single-faced paperboards produced through the single facer in the second step are conveyed to cross a bridge, and then preheated; fourthly, the single-faced paperboards in the third step are sequentially pasted with glue A and glue B, and bonded to form the corrugated paperboard; and fifthly, the corrugated paperboard bonded in the fourth step is heated and dried, and then the surfaces of the two sides of the heated and dried corrugated paperboard are coated with super hydrophobic and oileophobic interface coating. The bonding degree of the glue used in the production process of the double-faced waterproof corrugated paperboard is high, the waterproof and impact-proof performance is good, and the excellent-performance glue is adopted in cooperation of the super hydrophobic and oileophobic interface coating, so that the corrugated paperboard produced through the process is good in waterproof performance and high in bonding strength.

Description

technical field

[0001] The invention relates to the technical field of cardboard processing, in particular to a double-sided waterproof corrugated cardboard production process. Background technique

[0002] Packaging boxes made of corrugated cardboard are widely used in various fields of life and industry. Corrugated boxes are made of corrugated cardboard, and the quality of corrugated cardboard directly affects the quality of corrugated boxes. With the development of the corrugated box packaging market, the demand for waterproof corrugated boxes is increasing. The water resistance and moisture resistance of ordinary corrugated boxes are relatively poor, which cannot meet the needs of waterproof packaging. Contents of the invention

[0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a double-sided waterproof corrugated cardboard production process, so that the produced corrugated cardboard has good waterproof performance and high st...

[0022] 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.

[0023] A double-sided waterproof corrugated cardboard production process, the specific steps are as follows:

[0024] Step 1, glue making, glue includes A glue and B glue, (1) A glue is made according to the ratio of raw materials in parts by weight, the specific steps for making A glue are as follows: a. Add 90-100 parts of water and 6-8 parts of caustic soda, keep the temperature between 28°C -30°C, and stir at the same time for 1-2 minutes; then add 50-60 parts of edible starch, stir for 2-4 minutes; b, then add caustic soda 0.5 -0.7 parts, stir for 30-60 seconds; c, repeat step b, repeat 8-12 times; d, add 0.3-0.5 parts of stabilizer and 1-1.5 parts of additives, and then stir for 3-4 minutes; f, add 0.1-0.2 parts of borax, add onc...
