Embodiment 1

[0038] 1) Preparation of acrylic acid-sodium acrylate-acrylamide solution:

[0039] Prepare a NaOH solution with a concentration of 35%. Under normal temperature and electromagnetic stirring, use a dropper to slowly drop the prepared NaOH solution into 10% acrylic acid. Then, according to (acrylic acid + sodium acrylate): acrylamide = 4: The mass ratio of 1 weighs a certain amount of acrylamide and adds it to the above acrylic acid (sodium) solution, stirring continuously until the acrylamide is completely dissolved.

[0040] 2) Preparation of konjac glucomannan-(acrylic acid+sodium acrylate)-acrylamide composite humidity-conditioning material:

[0041] Weigh 0.1g of konjac glucomannan, add it to the above mixed solution, stir for 10 min to make the konjac glucomannan evenly mixed in the solution, add 0.05g of N, N-methylenebisacrylamide as cross-linking agent, continue stirring for 10 min. Add 0.1 g of Span-60 as a dispersant and 0.1 g of potassium persulfate as an initiato...

[0052] 1) Preparation of acrylic acid-sodium acrylate-acrylamide solution:

[0053] Prepare a NaOH solution with a concentration of 35%. Under normal temperature and electromagnetic stirring, use a dropper to slowly drop the prepared NaOH solution into 20% acrylic acid. Then, according to (acrylic acid + sodium acrylate): acrylamide = 4:1 Weigh a certain amount of acrylamide and add it to the above-mentioned acrylic acid (sodium) solution, and keep stirring until the acrylamide is completely dissolved.

[0054] 2) Preparation of konjac glucomannan-(acrylic acid+sodium acrylate)-acrylamide composite humidity-conditioning material:

[0055] Weigh 0.2g of konjac glucomannan, add it to the above mixed solution, stir for 10 min to make the konjac glucomannan evenly mixed in the solution, add 0.3g of N, N-methylenebisacrylamide as cross-linking agent, and continued to stir for 10 min. 0.5 g of Span-60 was added as a dispersant and 0.4 g of potassium persulfate as an initiator.

Abstract

The invention discloses a honeycomb paperboard with the function of regulating humidity. Including: upper paper, composite honeycomb core and lower paper; the composite honeycomb core is composed of a plurality of columnar honeycomb holes, each columnar honeycomb hole is filled with foaming and humidity-regulating materials, the upper end of the composite honeycomb core is glued with the upper paper, the composite honeycomb The lower end surface of the core is glued with the lower paper, and the central hole of each columnar honeycomb hole is perpendicular to the upper paper and the lower paper. In the present invention, the composite humidity-regulating material is filled in the honeycomb paperboard by in-situ foaming, and has a humidity-regulating function, so that the honeycomb paperboard can adjust the humidity of the inner space of the package to a suitable equilibrium humidity. The prepared composite honeycomb paperboard can actively adjust the humidity of the internal environment, and can maintain the humidity of the internal environment at (50±5)%. improve.

Description

technical field [0001] The invention relates to a honeycomb paperboard, in particular to a honeycomb paperboard with the function of regulating humidity. Background technique [0002] As a green packaging material with novel structure, light weight and low price, and excellent load-bearing and cushioning properties, honeycomb paperboard has attracted widespread attention and has been used in many fields such as packaging, construction, and agriculture. During the manufacture, storage and use of honeycomb paperboard, it may experience complex and changeable temperature and humidity environments. Due to the inherent hygroscopicity of paper packaging materials, the performance of honeycomb paperboard is quite sensitive to environmental conditions, especially changes in ambient humidity, and changes in humidity will cause changes in the performance of honeycomb paperboard. The one-way adjustment of the water content of the cardboard, that is, the use of methods such as coating ...
