Description
Technical Field
The utility model relates to the technical field of packaging paperboards, in particular to a composite paperboard with high buffering capacity.
Background
Corrugated cardboard is the main material of packing carton, but for some heavier products, the cardboard in its bottom is pressed excessively for the corrugated paper of cardboard collapses, loses the cushion effect, and the cardboard is easily torn, and intensity is not enough.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the present invention is to provide a composite paperboard with high buffering capacity, so as to solve the technical problems in the background art.
The technical scheme of the utility model is as follows:
a composite paperboard with high buffering capacity comprises a fiber layer, wherein a core layer, a panel layer and a waterproof layer are respectively arranged on two sides of the fiber layer; the core layer main body is supported by continuous wavy corrugated paper, and columnar paper tubes are inserted into upper and lower side recesses of the corrugated paper; the core layer is filled with foaming filler except the interior of the columnar paper tube.
Furthermore, the cross section of the columnar paper tube is circular or elliptical, and the columnar paper tube is transversely placed when the cylindrical paper tube is elliptical.
Further, the waterproof layer is a UV glazing layer, a wax coating layer, a polyethylene spray coating layer or a polypropylene spray coating layer.
Furthermore, the columnar paper cylinder and the corrugated paper are adhered into a whole by glue in advance, then the columnar paper cylinder and the corrugated paper are co-extruded with the foaming filler to form a core layer, and then the core layer, the fiber layer and the panel layer are subjected to hot press molding.
Further, the foaming filler is foaming polyurethane or foaming polyvinyl chloride.
The utility model has the advantages that:
the composite paperboard has the advantages that the fiber layer is added, so that the composite paperboard has strong tear resistance, the composite core layers on two sides and the continuous wavy corrugated paper in the core layers not only provide supporting capacity, but also provide the function of a framework for attaching the foaming filler, so that the foaming filler in the composite paperboard can not be easily cracked when the composite paperboard is subjected to bending moment, the rigidity is further improved when the columnar paper tube enters, the composite paperboard can play a good buffering role by matching with the foaming filler and the corrugated paper, the composite paperboard is used as the packaging bottom of large-scale equipment or a separation plate of a fragile product, and the composite paperboard is not easily torn or collapsed and has stronger protection capacity.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic front view of the present invention.
In the figure: 1-fiber layer, 2-core layer, 21-cylindrical paper tube, 22-corrugated paper, 23-foaming filler, 3-panel layer and 4-waterproof layer.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-2:
a composite paperboard with high buffering capacity comprises a fiber layer 1, wherein a core layer 2, a panel layer 3 and a waterproof layer 4 are respectively arranged on two sides of the fiber layer 1; the main body of the core layer 2 is supported by continuous wave-shaped corrugated paper 22, and columnar paper cylinders 21 are inserted into the upper and lower side recesses of the corrugated paper 22; the core layer 2 is filled with a foaming filler 23 except the inside of the cylindrical paper tube 21.
The utility model has the advantages that: the composite paperboard has strong tear resistance, the composite core layers 2 on two sides and the continuous wavy corrugated paper 22 in the core layer 2 not only provide supporting capacity but also provide the function of a framework, so that the foamed filler 23 (the foamed filler 23 can be foamed polyurethane or foamed polyvinyl chloride and the like) can be attached to the composite paperboard, the foamed filler 23 in the composite paperboard can not be easily cracked when the composite paperboard is subjected to bending moment, the columnar paper tube 21 can enter the composite paperboard to further improve the rigidity and can play a good buffering role by matching with the foamed filler 23 and the corrugated paper 22, the cross section of the columnar paper tube 21 can be circular or elliptical and can be transversely placed when the columnar paper tube 21 is elliptical, the circular or elliptical composite paperboard has better deformation stress and supporting capacity, the composite paperboard is used as the packaging bottom of large-scale equipment or as a separation board of fragile products and the like and is not easy to tear or collapse, and the protection capability is stronger.
The waterproof layer 4 is the last process of composite paperboard processing, and a UV glazing layer, a wax coating layer, a polyethylene spray coating layer or a polypropylene spray coating layer and the like can be selected according to actual requirements.
In consideration of the actual production requirement, the columnar paper tube 21 and the corrugated paper 22 are adhered into a whole by glue in advance, then the columnar paper tube and the corrugated paper are co-extruded with the core layer 2 together with the foaming filler 23, and then the core layer, the fiber layer 1 and the panel layer 3 are subjected to hot press molding, so that the production difficulty can be reduced.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
