Problems solved by technology

[0003] However, in the process of using corrugated cardboard, it is very easy to appear: the skin on the corrugated cardboard is not well bonded, the fibers on the corrugated cardboard are easily damaged, the stress resistance is greatly reduced, the quality is not guaranteed, and the amount of glue is large. The heat energy consumption of steam is large, and the production speed is slow. In order to solve the above problems, the amount of sizing needs to be increased, the amount of waste products increases, and the production efficiency is reduced.

Abstract

The invention provides a low-pressure paste additive, belongs to the technical field of paperboard production, and specifically relates to a low-pressure paste additive. The low-pressure paste additive comprises starch, an antifoaming agent, sodium metasilicate pentahydrate, polyvinyl alcohol, sodium carboxymethylcellulose, ethoxylated dipentaerythritol, acrylic acid, maleic anhydride, ethynyl diol, a filling material and dioctyl pyrophosphate. According to the invention, a mixed paste has excellent shear-force resistance and heat resistance, and the stable viscosity of the paste is maintainedin the process of recycling, so the paste has great stability; a molecule in an additive can replace a hydroxyl group in a starch molecule, so stable crosslinking is formed; the starch molecule is encircled by an additive molecule, and capacities of resisting heat and shear force are reinforced, so the viscosity stability of the paste is maintained in the process of recycling; thus, the situationthat continuous size decrease and sharp viscosity decrease of the starch molecule due to shearing and heating during recycling causes poor bonding is reduced or avoided.

Description

technical field [0001] The invention belongs to the technical field of cardboard production, and in particular relates to a low-pressure paste additive. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "pit sheet" or "corrugated paper") and a layer of cardboard (commonly known as "kraft card"). It has high mechanical strength, can withstand bumps and falls during handling, and is a necessary material for modern packaging. Paste will be used in the process of preparing corrugated cardboard, and the quality such as flatness of corrugated cardboard can be improved through paste. [0003] However, in the process of using corrugated cardboard, it is very easy to appear: the skin on the corrugated cardboard is not well bonded, the fibers on the corrugated cardboard are easily damaged, the stress resistance is greatly reduced, the quality is not guaranteed, and the am...
