Description
Technical Field
The utility model relates to the technical field of packaging, in particular to a waterproof and mildewproof paperboard.
Background
The paperboard is also called board paper, and is a thick paper sheet formed by interweaving fibers and processed by various paper pulps, the distinction between the paperboard and the paper is usually distinguished by basis weight and thickness, and can be classified into packaging paperboards such as box paperboard, kraft box paperboard, yellow paperboard, white paperboard, impregnated liner paperboard and the like according to the application; industrial technical paperboards such as electrical insulation paperboards, asphalt waterproof paperboards, and the like. In order to ensure the safety of packaged articles, the existing paper board for packaging has extremely high requirements on waterproof and mildewproof performance, the currently adopted waterproof structure is generally that a layer of plastic film is covered and adhered on the outer side of the paper board, but the paper board is very easy to be soaked by moisture because the film is very easy to scratch, and organic matters of the paper board are easy to deteriorate and discolor due to the growth of mildew. In addition, to accompany corrugated paper layer's cardboard, in case moisture immerses corrugated paper layer, then can greatly reduced corrugated paper layer's structural strength, reduce the supporting role to inside and outside double-layered paper layer, the interval between the inside and outside double-layered paper layer will dwindle greatly for whole speed of being soaked then.
SUMMERY OF THE UTILITY MODEL
The present invention aims to provide a waterproof and mould-proof paperboard which alleviates the above problems.
In order to alleviate the above problems, the technical scheme adopted by the utility model is as follows:
the utility model provides a waterproof and mildewproof paperboard which comprises a first paper clamping layer, a second paper clamping layer and a corrugated paper layer clamped between the first paper clamping layer and the second paper clamping layer;
one side of the first paper clamping layer, which is back to the corrugated paper layer, is provided with a first waterproof coating, and one side of the first paper clamping layer, which is facing the corrugated paper layer, is sequentially provided with a second waterproof coating and a first dry water absorption layer which covers the second waterproof coating and is in contact with the corrugated paper layer;
a third waterproof coating is arranged on one side, back to the corrugated paper layer, of the second paper clamping layer, a fourth waterproof coating and a second dry water absorption layer which covers the fourth waterproof coating and is in contact with the corrugated paper layer are sequentially arranged on one side, facing the corrugated paper layer, of the second paper clamping layer;
the moisture absorption rates of the first dry water absorption layer and the second dry water absorption layer are respectively greater than the moisture absorption rates of the first paper-sandwiched layer, the second paper-sandwiched layer and the corrugated paper layer.
Compared with the prior art, the utility model has the beneficial effects that:
the front and back surfaces of the two paper-sandwiched layers are respectively provided with the waterproof coating, so that the overall waterproof performance of the paperboard is greatly improved, and the mildew possibility of the paperboard is reduced; corrugated paper layer is equivalent to for the braced frame of whole cardboard, and second waterproof coating and fourth waterproof coating are all not outwards, can not receive the direct destruction of foreign object, and corrugated paper layer presss from both sides between two dry layers that absorb water, have ensured corrugated paper layer not wet by the moisture, have ensured the structural high stability of cardboard.

Examples
Referring to fig. 1, the present embodiment provides a waterproof and mildewproof paperboard, which includes a first paper sandwiching layer 1, a second paper sandwiching layer 3, and a corrugated paper layer 2 sandwiched between the first paper sandwiching layer 1 and the second paper sandwiching layer 3;
a first waterproof coating 4 is arranged on one side of the first paper clamping layer 1 back to the corrugated paper layer 2, a second waterproof coating 5 and a first dry water absorption layer 6 which covers the second waterproof coating and is in contact with the corrugated paper layer 2 are sequentially arranged on one side of the first paper clamping layer 1 facing the corrugated paper layer 2;
a third waterproof coating 8 is arranged on one surface of the second paper-sandwiched layer 3, which is opposite to the corrugated paper layer 2, and a fourth waterproof coating 9 and a second dry water-absorbing layer 7 which is covered on the fourth waterproof coating 9 and is in contact with the corrugated paper layer 2 are sequentially arranged on one surface of the second paper-sandwiched layer 3, which is opposite to the corrugated paper layer 2;
the moisture absorption rates of the first dry water absorption layer 6 and the second dry water absorption layer 7 are respectively greater than the moisture absorption rates of the first paper-sandwiched layer 1, the second paper-sandwiched layer 3 and the corrugated paper layer 2.
In this embodiment, the processing technology of the paperboard can be various, and one of the technologies is briefly described here: firstly, coating a first waterproof coating 4 on one surface of the first paper clamping layer 1, which is opposite to the corrugated paper layer 2, turning to the other surface to coat a second waterproof coating 5 after drying, and bonding the first dry water-absorbing layer 6 to the second waterproof coating 5 after the second waterproof coating 5 is dried; the processing of the second paper-sandwiched layer 3 is similar to that of the first paper-sandwiched layer 1; finally, the corrugated paper layer 2 is bonded between the first dry water absorption layer 6 and the second dry water absorption layer 7.
In this embodiment, the desiccant water-absorbing layer can be made of a material with strong moisture-absorbing ability, or can be formed by combining a plurality of structures, for example, a film is covered on the waterproof coating layer facing the corrugated paper layer 2, then a layer of desiccant powder is covered on the film, and finally a layer of film is covered and compacted. For a combined desiccant absorbent layer, the structural stability is relatively not so high, perhaps a little down to the valleys of the corrugated paper layer 2, but this does not affect its dry protection of the corrugated paper layer 2.
This embodiment the cardboard when installing additional for the packing box, cardboard edge part need pass through the sticky tape banding, perhaps adopts other modes banding, as long as do not make the edge expose can the gap of intaking can.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
