Description

Dampproofing corrugated container board

Technical Field

The utility model relates to a corrugated container board, especially a dampproofing corrugated container board.

Background

Corrugated board is also called corrugated board. Is formed by bonding at least one layer of corrugated paper and one layer of boxboard (also called boxboard), and has better elasticity and extensibility. The method is mainly used for manufacturing cartons, the sandwich of the cartons and other packaging materials of fragile commodities. The raw paper board similar to yellow paper board is made up by using straw pulp of earth method and waste paper through pulping, then mechanically processing and rolling into corrugated form, then using sodium silicate as adhesive on its surface and sticking it with cardboard paper. The existing corrugated boards are generally not subjected to moisture-proof treatment, the corrugated paper therein is easy to be affected with moisture to cause the reduction of mechanical strength, and the supporting effect of the corrugated boards is greatly reduced.

SUMMERY OF THE UTILITY MODEL

In view of the above insufficiency, the present invention aims to provide a moisture-proof corrugated board to solve the technical problems mentioned in the background art.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a moisture-proof corrugated cardboard comprises

A corrugated paper layer;

the box board is fixedly arranged on the inner side surface and the outer side surface of the corrugated board;

corrugated paper layer includes corrugated container board, be provided with the one deck and half permeate the rete on corrugated container board's the lateral surface, it absorbs water the layer to be provided with the one deck on half permeating the surface of rete, it is provided with the first sealing layer of one deck on the surface on layer to absorb water, be provided with the one deck second sealing layer on corrugated paper layer's the medial surface.

Further, the water absorption layer is arranged in a grid shape.

Furthermore, a plurality of reinforcing nails are uniformly distributed on the corrugated paper layer, and the frame reinforcing nails are clamped on the inner side and the outer side of the corrugated paper layer in an I shape.

Furthermore, the surfaces of the first sealing layer and the second sealing layer, which face away from the corrugated board, are rough surfaces, and the box board is provided with a plurality of reinforcing glue points which are fixedly connected between the box board and the corrugated paper layer.

Furtherly, the boxboard all establishes a plurality of support pegs towards corrugated paper layer on the surface, the one end fixed connection of support peg is in the trough of corrugated paper, set up on the support peg and have the ball that holds the chamber, hold and fill the drier in the ball, it all establishes the bleeder vent on the surface to hold the ball.

The working principle and the beneficial effects are as follows: when the corrugated paper is damp because of the external environment, the moisture in the corrugated board can enter the water absorbing layer with stronger water absorbing capacity through the semi-permeable film layer and is locked in the water absorbing layer, so that the moisture content in the corrugated board is effectively reduced, the corrugated board can effectively keep the self-drying in the damp environment, and the mechanical strength of the corrugated paper layer is also ensured. In addition, the existence of the first sealing layer and the second sealing layer can effectively reduce the contact between the corrugated paper layer and the water absorption layer and external water vapor, thereby greatly reducing the probability of moisture regain of the corrugated board.

Reference numerals: 100. the corrugated paper layer 110, the corrugated board 120, the semi-permeable film layer 130, the water absorbing layer 140, the first sealing layer 150, the second sealing layer 160, the frame fixing nail 200, the boxboard 300, the reinforcing glue point 400, the support nail 410, the accommodating ball 420, the vent hole 500 and the desiccant.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The moisture-proof corrugated cardboard shown in fig. 1 and 2 includes a corrugated paper layer 100 for ensuring mechanical properties of the corrugated cardboard, and a linerboard 200 fixedly connected to the corrugated paper layer is respectively disposed on an inner side and an outer side of the corrugated cardboard. Specifically, the corrugated paper layer includes a corrugated cardboard 110, a semi-permeable film layer 120 is disposed on an outer side surface of the corrugated cardboard, the semi-permeable film layer has a water molecule passing ability, a water absorbing layer 130 is disposed on an outer surface of the semi-permeable film layer, the water absorbing layer is made of a material having a strong water absorbing ability, and a first sealing layer 140 is disposed on an outer surface of the water absorbing layer. Meanwhile, a second sealing layer 150 is arranged on the inner side surface of the corrugated paper. In the scheme, the side of the corrugated board facing outwards after being made into the carton is called as the outer side, and the side is called as the inner side on the contrary.

As a further improvement of the above embodiment, the water absorbent paper is provided in a lattice shape. Through this kind of form make and to pass the space that absorbs water the layer between semi-permeable membrane layer and the first sealing layer and carry out firm connection, guaranteed that the layer that absorbs water semi-permeable membrane and first seal membrane people can be inseparable combine together.

As a further improvement of the above embodiment, in order to further improve the stability of the corrugated cardboard, a plurality of reinforcing nails 160 are uniformly distributed on the corrugated paper layer. Specifically, the reinforcing nail is I-shaped, and two ends of the reinforcing nail are clamped on the inner side and the outer side of the corrugated paper layer.

As a further improvement of the above embodiment, in order to improve the bonding strength between the corrugated cardboard layer and the linerboard, the surfaces of the first sealing layer and the second sealing layer facing away from the corrugated cardboard are rough surfaces, and a plurality of reinforcing glue points 300 are provided on each linerboard, and the reinforcing glue points are fixedly connected between the linerboard and the corrugated cardboard layer.

As a further improvement of the above embodiment, in order to increase the compressive strength of the corrugated cardboard, a plurality of support pins 400 are provided on the surface of the linerboard facing the corrugated paper layer. Specifically, one end of the supporting nail is fixedly connected in the corrugation of the corrugated paper. In addition, in order to improve the moisture resistance, a hollow accommodating ball 410 is further arranged on the support nail, a drying agent 500 is filled in the accommodating ball, and a plurality of through vent holes 420 are formed in the surface of the accommodating ball.
