Problems solved by technology

For example, Chinese patent CN2018214649514 discloses a new type of paper honeycomb. This technical solution is fixedly installed with a rib plate on the top of the honeycomb cardboard. The top of the rib plate is fixedly connected with the bottom end of the anti-penetration layer. Layer penetration can effectively improve the folding resistance of honeycomb paperboard, thereby avoiding the problem that the paper honeycomb is easily deformed by local extrusion during the packaging and transportatio

Embodiment 1

[0016] A production process for improving the insufficient folding resistance of honeycomb paperboard, the specific production process is as follows:

[0017] 1) Weigh an appropriate amount of sodium hydroxide and dissolve it in deionized water, then add a small amount of urea to prepare a solution with a mass fraction of sodium hydroxide of 5% and a mass fraction of urea of ​​15%, and then use acrylic acid to adjust the pH of the solution to 10.0, Add bamboo fiber powder with 10% of the total mass of the solution, 300W ultrasonic dispersion for 20 minutes, and place it at -10°C for 8 hours to obtain a bamboo fiber suspension, then adjust the pH value of the suspension to 6.0 with acrylic acid, and add acrylic acid to the suspension in turn N, N-methylenebisacrylamide and ammonium persulfate with a mass fraction of 0.25% and 0.2% were heated in a water bath at 75°C for 2 hours, and cooled to room temperature to obtain a pretreated bamboo fiber dispersion;

Abstract

The invention discloses a production process for improving insufficient folding resistance of a honeycomb paperboard, and relates to the technical field of paper processing. The specific production process comprises the following steps: 1) treating bamboo fiber powder to obtain a pretreated bamboo fiber dispersion; 2) preparing pulp; (3) adding the pulp into fiber paper pulp, carrying out papermaking forming to obtain body paper, and then soaking the body paper into the pulp to obtain pretreated body paper; 4) carrying out copper plating treatment on the pretreated body paper to obtain folding-resistant raw paper; and 5) processing the folding-resistant body paper to prepare the honeycomb paperboard. The paper load energy can be cooperatively dissipated by constructing in the paper, and the structure generated by a stress concentrating phenomenon in paper is inhibited, so the paper has good folding resistance; and meanwhile, a composite coating with excellent folding resistance is formed on the surface of the paper, so the folding resistance of the paper is further improved, the prepared honeycomb paper is not prone to deformation under the extrusion effect of external force, and the honeycomb paperboard can be better applied to the field of packaging and transportation.

Description

technical field [0001] The invention belongs to the technical field of paper processing, and in particular relates to a production process for improving the insufficient folding resistance of honeycomb paperboard. Background technique [0002] Honeycomb paper is made according to the principle of honeycomb structure in nature. It connects corrugated base paper into countless hollow three-dimensional regular hexagons by glue bonding method to form a whole force-bearing part-paper core, and glues face paper on both sides. A new type of sandwich structure environmental protection and energy saving material. Honeycomb paper has the advantages of light weight, high flat compression strength and good cushioning performance, and is widely used in construction, packaging and transportation, and agriculture. [0003] In the field of packaging and transportation, honeycomb paper has good cushioning performance, so that it can be used as a cushioning liner or isolation board for packa...
