Problems solved by technology

[0002] With the continuous improvement of people's packaging requirements, people also have higher requirements for the strength of packaging paper. A little damage will affect the damage of goods in the logistics process. Most of the current packaging paper is formed by multi-layer paper and then compounded. , due to the insufficient bonding force between the paper layers, the problem of delamination and cracking often occurs, which seriously affects the use of composite paper. Therefore, it is necessary to study the production process of composite paper that is resistant to damage and does not delaminate.

Embodiment 1

[0037] A method for producing burst-resistant and non-delaminated paper using amphoteric starch, comprising the following steps:

[0038] (1) Preparation of amphoteric starch glue: see figure 1 with figure 2 , first choose amphoteric starch, due to the packaging and storage problems of amphoteric starch, before use, the powder of amphoteric starch will gather into agglomerates, which will affect the mixing process. , in order to facilitate sufficient mixing and stirring, so it is necessary to powder the amphoteric starch through a powder-opening device and then pass it into the first dissolving tank 1, and then pass it into the first dissolving tank 1 while the amphoteric starch is passing into the first dissolving tank 1 Continuously pour in clean water and stir continuously to fully mix and dissolve the amphoteric starch and clear water to obtain amphoteric starch liquid, then heat the gelatinized amphoteric starch liquid to obtain amphoteric starch concentrated glue, and ...

Embodiment 2

[0049] A method for producing burst-resistant and non-delaminated paper using amphoteric starch, comprising the following steps:

[0050] (2) Preparation of amphoteric starch glue: see figure 1 with figure 2 , first choose amphoteric starch, due to the packaging and storage problems of amphoteric starch, before use, the powder of amphoteric starch will gather into agglomerates, which will affect the mixing process. , in order to facilitate sufficient mixing and stirring, so it is necessary to powder the amphoteric starch through a powder-opening device and then pass it into the first dissolving tank 1, and then pass it into the first dissolving tank 1 while the amphoteric starch is passing into the first dissolving tank 1 Continuously pour in clean water and stir continuously to fully mix and dissolve the amphoteric starch and clear water to obtain amphoteric starch liquid, then heat the gelatinized amphoteric starch liquid to obtain amphoteric starch concentrated glue, and ...

Abstract

The invention relates to a method for producing burst-resistant non-layering paper from amphoteric starch. The method comprises the following steps: fully dissolving the amphoteric starch in clear water, performing heating for gelatinizing, and performing dilution to obtain an amphoteric starch glue; fully mixing and stirring native starch and clear water to prepare a native starch liquid; addingthe prepared amphoteric starch glue into a paper pulp, and performing sufficient stirring to blend the paper pulp; papermaking the blended paper pulp in a fourdrinier machine to obtain wet paper webs;spraying the native starch liquid on the wet paper webs; attaching the sprayed wet paper webs to form a composite wet paper web, and heating and curing the composite wet paper web; and drying, calendaring, coiling and slitting the composite wet paper web to obtain the burst-resistant non-layering paper. The blended amphoteric starch glue is added into the paper pulp in order to improve the strength of short fibers, the native starch liquid is uniformly sprayed between paper layers, and the cured starch glue can improve the bonding strength between the paper layers, so the purpose of producingthe burst-resistant non-layering paper is achieved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a method for producing burst-resistant and non-delaminated paper using amphoteric starch. Background technique [0002] With the continuous improvement of people's packaging requirements, people also have higher requirements for the strength of packaging paper. A little damage will affect the damage of goods in the logistics process. Most of the current packaging paper is formed by multi-layer paper and then compounded. , due to the insufficient bonding force between the paper layers, the problem of delamination and cracking often occurs, which seriously affects the use of composite paper. Therefore, it is necessary to study the production process of composite paper that is resistant to damage and does not delaminate. Contents of the invention [0003] Therefore, the object of the present invention is to provide a method for applying amphoteric starch to produce...
