Problems solved by technology

With the continuous expansion of the papermaking industry and the continuous expansion of the application of pulp, the supply of wood, which was originally the main raw material for papermaking, is gradually in short supply, resulting in excessive deforestation and affecting the ecological environment. Therefore, it is necessary to seek new substitutes for raw materials. At the same time, corrugated cardboard In the application process, there is also the problem of poor compressive strength

Embodiment 1

[0016] A high-strength corrugated cardboard is characterized in that it consists of three layers, the middle layer is a high-strength pulp layer, the inner layer is an active carbon layer, and the outer layer is a foam layer.

[0017] Further, the middle layer includes the following raw materials in parts by weight: 2 parts of glass fiber, 30 parts of cumin stalk, 0.2 parts of sodium lauryl sulfate, 5 parts of polypropylene fiber, and 4 parts of starch.

[0018] Further, the preparation method of the intermediate layer is as follows:

[0019] (1) Put glass fiber, polypropylene fiber, and diatomaceous earth in an oven at 120°C, dry for 5 hours, and then place them in a ball mill for 1 hour;

[0020] (2) Cut the fennel stems into small pieces with a length of 1 cm, put them in a freeze dryer, freeze-dry them for 60 minutes, take them out, put them in boiling water 10 times their volume, add sodium lauryl sulfate, boil for 30 minutes, take them out ;

[0021] (3) Mix and refine...

Abstract

The invention discloses a high-strength corrugated board. The high-strength corrugated board has a multilayer structure; glass fiber, polypropylene fiber and fennel stems have a synergistic effect ona middle layer; due to the combination of the three fibers, the structural strength of the high-strength corrugated board is obviously higher than the structural strength of a single fiber, so that the promotion of the compressive strength of the corrugated board is benefited; wastes are effectively utilized, wastes are turned into wealth, energy is saved and environmental pollution can be avoided; an inner layer is made from activated carbon and nanometer titania, is capable of purifying air in a box and preventing odor and is suitable for the packaging of garden stuff and food; an outer layer is made of polylactic acid foam, has a buffering function and is capable of reducing the damage possibility during a transportation process.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high-strength corrugated cardboard. Background technique [0002] Corrugated cardboard is a corrugated board formed by liner board and corrugated sticks. It is generally divided into two types: single corrugated cardboard and double corrugated cardboard. It is simple and versatile, so it is favored by people. With the continuous expansion of the papermaking industry and the continuous expansion of the application of pulp, the supply of wood, which was originally the main raw material for papermaking, is gradually in short supply, resulting in excessive deforestation and affecting the ecological environment. Therefore, it is necessary to seek new substitutes for raw materials. At the same time, corrugated cardboard In the application process, there is also the problem of poor compressive strength. Contents of the invention [0003] In view of the above proble...
