Description

Corrugated cardboard with strong compression and roll resistance

technical field

The utility model relates to the technical field of corrugated cardboard, in particular to a corrugated cardboard with strong compression resistance and anti-roll.

Background technique

Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper and at least one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling. Corrugated core paper interlayer is also known as corrugated paper core. Corrugated paper core is divided into five types according to the size of corrugated: A, B, C, E, F. Each type of corrugated paper core has different characteristics, so different types of corrugated paper The core determines the strength and cushioning of corrugated board, but the strength and cushioning are inversely proportional. The greater the strength, the smaller the cushioning performance. It is difficult for traditional corrugated board to have both strong strength and strong cushioning, and Corrugated cardboard has poor anti-roll ability due to the wavy shape of the corrugated cardboard core, while the traditional anti-roll corrugated cardboard only overlaps two layers of corrugated cardboard cores, so that the corrugated cardboard has anti-curling in both horizontal and vertical directions, but the cardboard is only with the corrugated cardboard core. The frond peaks are pasted by glue, the contact area is small, and it is easy to open the glue when it is curled; when part of the frond peaks and the cardboard are glued, the frond peaks are displaced and deformed under strong pressure, resulting in local collapse of the corrugated board, so it is necessary to Improve.

The upper corrugated core layer includes the upper corrugated paper layer 13 and the upper cardboard layer 11 respectively pasted on the upper surface and the lower surface of the upper corrugated paper layer 13, and the lower corrugated core layer includes the lower corrugated paper layer 23 and is respectively pasted on the upper surface of the lower corrugated paper layer 23 and 11. The lower cardboard layer 21 on the lower surface, the upper corrugated cardboard layer 13 and the lower corrugated cardboard layer 23 are vertically arranged;

The opposite surfaces of the two upper cardboard layers 11 are provided with a plurality of upper corrugated fixing rib groups 12 at intervals along the length direction of the waves of the upper corrugated cardboard layer 13. The stunned peaks are embedded in the corresponding upper fixed gaps, respectively.

The opposite surfaces of the two lower cardboard layers 21 are provided with a plurality of lower corrugated fixing rib groups 22 at intervals along the length direction of the waves of the lower corrugated cardboard layer 23. The peaks are respectively embedded in the corresponding lower fixed gap;

The upper corrugated core layer and the lower corrugated core layer are respectively provided with a plurality of cylindrical airbags 3, and each cylindrical airbag 3 is arranged at the gap between the upper corrugated paper layer 13 and the upper cardboard layer 11 and the lower corrugated paper layer 23 and the lower cardboard. at the pores between layers 21 .

The traditional corrugated cardboard has poor anti-curling ability, and the connection area between the peak and the cardboard is small. And the lower corrugated cardboard layer 23 is anti-curling from both horizontal and vertical directions, and the upper corrugated fixing rib group 12 and the lower corrugated fixing rib group 22 fix the corrugated peaks of the upper corrugated cardboard layer 13 and the lower corrugated cardboard layer 23, increasing their connection area, and it is not easy when curling occurs. Degumming, the strength is greater; the cylindrical airbag 3 supports the gap between the upper corrugated cardboard layer 13 and the lower corrugated cardboard layer 23, has strong compressive capacity, has a certain buffering capacity, does not occupy the thickness of the corrugated cardboard alone, and prevents the collapse of the peak after degumming. Strong compressive ability, two shock absorption layers 6 enhance the buffering ability of corrugated cardboard; high strength, strong compressive ability, strong anti-curling ability and not easy to degumming.

Specifically, the connecting layer includes an upper connecting cardboard 72, a lower connecting cardboard 74, and a honeycomb cardboard 73 pasted between the upper connecting cardboard 72 and the lower connecting cardboard 74. The upper surface of the upper connecting cardboard 72 and the lower surface of the lower connecting cardboard 74 are respectively After being pasted with the two shock absorption layers 6 , the gaps between the upper connecting paperboard 72 and the lower connecting paperboard 74 and the honeycomb paperboard 73 are filled with flame retardant. The honeycomb paperboard 73 is located between the upper corrugated core layer and the lower corrugated core layer. The honeycomb paperboard 73 itself has a certain anti-curling ability and strong compressive ability. The honeycomb paperboard 73 connects the upper corrugated core layer and the lower corrugated core layer to further strengthen In order to improve the compressive resistance and anti-curling ability of corrugated cardboard, flame retardant is filled in the gap of honeycomb cardboard 73 to block the upper corrugated core layer and the lower corrugated core layer, and prevent high temperature or flame from burning through the corrugated cardboard.

Specifically, the upper and lower surfaces of the upper connecting paperboard 72 and the lower connecting paperboard 74 are respectively coated with a layer of flame retardant coating 71 . The flame retardant coating 71 further prevents the flame from igniting the corrugated cardboard, and further enhances the fire resistance of the corrugated cardboard.

Specifically, a graphite heat insulation layer 5 is pasted between the upper cardboard layer 11 located below the upper corrugated cardboard layer 13 and the shock-absorbing layer 6 , and the lower cardboard layer 21 located above the lower corrugated cardboard layer 23 and the shock-absorbing layer 6 are pasted between There is another graphite insulating layer 5 . The heat transfer is isolated by the graphite insulating layer 5. When one side of the upper corrugated core layer or the lower corrugated core layer is ignited by flame, the heat is blocked from transferring to the other side, thereby giving the corrugated cardboard thermal insulation properties.

Specifically, the cross-sectional shape of the upper corrugated cardboard layer 13 and the lower corrugated cardboard layer 23 is a continuous "V" shape. The "V"-shaped upper corrugated cardboard layer 13 and the lower corrugated cardboard layer 23 have the characteristics of high strength, and cooperate with the cylindrical air bag 3 to have both high compression resistance and high buffering ability.

Specifically, the cross-sectional shape of the upper corrugated paper layer 13 is a continuous "V" shape, and the cross-sectional shape of the lower corrugated paper layer 23 is a continuous "U" shape.

Specifically, the upper surface of the upper cardboard layer 11 above the upper corrugated cardboard layer 13 and the lower surface of the lower cardboard layer 21 below the lower corrugated cardboard layer 23 are respectively coated with a waterproof film layer 4 . When the corrugated cardboard is made into a packing box, the two waterproof film layers 4 are located on the inner side and the outer side of the packing box respectively, so that both the inside and the outside of the packing box are waterproof, so as to avoid the liquid invading the corrugated cardboard during transportation. Its strength decreases.

Specifically, the shock absorption layer 6 is a sponge layer. The sponge layer has strong buffering capacity and low cost, and the double-layer shock absorption layer 6 makes the buffering capacity of the corrugated cardboard better.

Specifically, the thickness of the upper cardboard layer 11 is greater than or equal to the thickness of the lower cardboard layer 21 . When the corrugated cardboard is made into a packing box, the thickness of the upper cardboard layer 11 on the outer side is relatively thick, so that it has strong wear resistance and prevents the upper cardboard layer 11 from being broken due to handling friction.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope, and the content of this description should not be construed as Limitations of the present invention.
