Problems solved by technology

Packaging cardboard has the characteristics of light weight and convenience, but its strength is low, it is easy to crack, and its waterproof performance is poor
However, the existing starch-based cardboard bonding additive method is relatively simple, the time required for production is long, and the process is unreasonable, resulting in poor quality of the starch binder, and only 2-4 layers of corrugated cardboard can be produced, with low strength. , easy to crack

Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific examples.

[0026] A five-layer corrugated paper production process, comprising the following steps,

[0027] 1) Carry out heat treatment to face paper and core paper respectively, and carry out gluing treatment to the surface of corrugated base paper;

[0028] 2) Composite the surface paper and core paper with a layer of corrugated base paper coated with glue respectively to form two single-sided corrugated boards;

[0029] 3) The inner paper is added, the inner paper is located between two single-sided corrugated cardboards, and is glued by a gluing machine, and then compounded;

[0030] 4) cooling after drying.

[0031] The binding agent used for gluing comprises the following components by weight, starch: 200 parts, sodium hypochlorite: 22 parts, strong ca...

Abstract

The invention discloses a process for producing five layer corrugated paper, and relates to the technical field of packaging materials, and the process comprises the following steps, 1) respectively heating surface paper and core paper, and gluing the surface of raw corrugated paper; 2) respectively compounding the surface paper and the core paper with one layer of the glued raw corrugated paper to form two single-side corrugated paper plates; 3) adding inner paper between the two single-side corrugated paper plates, then using a gluing machine for gluing, and compounding; and 4) drying and cooling. The process is novel process, and the five layer corrugated paper has the advantages of high strength, no easy cracking, low raw material cost, short production time and high adhesive quality.

Description

[0001] Technical field: [0002] The invention relates to the technical field of packaging materials, in particular to a production process of five-layer corrugated paper. [0003] Background technique: [0004] Packaging cardboard is the general term for cardboard used for packaging. Including white cardboard, yellow cardboard, kraft cardboard, corrugated cardboard, etc. It is generally required to have strong folding resistance and good flexibility. It is made of wood, rice straw, etc., pulped by different methods, and copied on a cardboard machine. It is mainly used to make packaging cartons, and also used as packaging materials or printing materials. Packaging cardboard has the characteristics of light weight and convenience, but its strength is low, it is easy to crack, and its waterproof performance is poor. However, the existing starch-based cardboard bonding additive method is relatively simple, the time required for production is long, and the process is unreasonab...
