Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

Embodiment 1, as shown in fig. 1-2, a heavy waterproof corrugated cardboard for an elevator comprises an inner paper 1, a middle corrugated support layer 2 and a surface paper 3 which are bonded in sequence from inside to outside, wherein the grammage of the inner paper 1 is greater than that of the surface paper 3, and the grammage of the surface paper 3 is more than 200 g/square meter. The grammage of the individual sheets of paper involved in the intermediate corrugated support layer 2 should each exceed 100 grams per square meter.

The inner paper 1 and the surface paper 3 can both adopt beautiful cardboard and preferably adopt flat and solid structures, the middle corrugated supporting layer 2 is a supporting layer structure with corrugated paper, the inner paper 1 can better protect an elevator and related equipment at the inner side, and the inner side and the outer side refer to the directions of the inner side and the outer side of a packaging body, such as a packaging box, a packaging box and the like, after the corrugated board is manufactured into the packaging body, namely the directions of the inner side and the outer side when the corrugated board is used for packaging articles. By increasing the compactness of the inner side, under the conditions of shaking, collision, impact or sudden stop of the truck and the like, the packing body has better buffering and protection to heavy objects with a plurality of rigid edges and corners such as elevators and the like, ensures that the objects are not easy to damage the inner side structure of the paper board in the process of turnover, ensures the stability of the structure of the packing body, the outer part of the paperboard is in the bad condition, the main contact is the parts between the surfaces of the box body, on the ground or on the ground of the cargo compartment, so that the grammage thereof can be reduced, and the face paper 3 is also attached to the intermediate corrugated support layer 2 to support the inner liner paper 1, so the thickness can be properly reduced, and then the strength required by the design is achieved through gram weight, the whole structure design is very suitable for the transportation of the elevator and the related equipment, the packaging box made of the paperboard is very suitable for packaging elevators and related equipment and transporting. The waterproof film f is designed to achieve a better waterproof effect, particularly, a box body like an elevator package needs to be stacked in the open air sometimes, a better waterproof structure is particularly needed to protect the box body in case of heavy rain and the like, and otherwise, excessive moisture seeps into the box body to damage the corrugated board and the structure of the packaged elevator and other objects. Therefore, although the corrugated board has a certain water-resisting capacity, all the structural layers are always paper, moisture can permeate, the turnover and transportation process still lasts for a period of time, and the waterproof performance needs to be better guaranteed, so that a waterproof film f is further designed to be bonded on the outer side of the surface paper 3. The waterproof film f can be a film made of a polymer material such as a PE film. In order to improve the waterproof performance of the corrugated board, the outer side of the surface paper 3, namely the outermost part of the whole paper board after being made into a package body, is protected in the peripheral waterproof performance, and the internal structure can be well protected.

Further, the face paper weight of 3 g is more preferably between 300-400 g/m, and the back paper weight of 1 g is more preferably between 400-500 g/m.

The middle corrugated support layer 2 comprises at least one core paper 21 and two corrugated papers 22, the number of the corrugated papers 22 is 1 more than that of the core paper 21, and the core paper 21 is bonded between the two adjacent corrugated papers 22. The core paper 21 may be made of kraft paper and preferably has a flat solid structure. The corrugated paper 22 can be in a wavy structure or a U-shaped structure, the corrugated paper 22 is usually high corrugated paper, and can be made into wavy shape directly by the existing process when the paper is made, or can be formed by bending and molding the original flat high corrugated paper or forming the corrugated shape by other processes, the high corrugated paper is the most popular plate produced by the existing corrugated paper board, and the wave crests and the wave troughs of all the corrugations of the corrugated paper 22 are arranged in the inward and outward directions and are supported by the inward and outward directions. The grammage of the core paper 21 is preferably controlled to be between 190 and 220 grams per square meter, and the grammage of the corrugated paper 22 is preferably controlled to be between 100 and 190 grams per square meter.

Further preferably, the grammage of each piece of the corrugated paper 22 gradually decreases from inside to outside. That is, the grammage of the innermost sheet of the corrugated paper 22 is the largest, and the grammage of the outermost sheet of the corrugated paper 22 is the smallest, and gradually decreases from the middle. The grammage of each sheet of the core paper 21 is the same as much as possible. In addition, as can be seen from the foregoing, the grammage of the core paper 21 is preferably larger than that of the corrugated paper 22. The grammage of the face paper 3 is preferably greater than that of the core paper 21, so that the core paper 21 is in the middle position, and not only can the corrugated paper 22 be better supported, so that the stability of the middle structure is ensured, but also the buffer performance cannot be influenced by too hard.

The overall thickness of the liner paper 1, the middle corrugated support layer 2 and the face paper 3 is more than 8 mm. The thickness of the corrugated paper 22 is more than 3 mm, and the distance between the inside and the outside of the wave crest and the wave trough is controlled to be more than 3 mm, and more preferably about 5 mm. In addition, the distance between the nearest wave crest and wave trough of the corrugation of the corrugated paper 22 perpendicular to the inner and outer directions should be controlled within 8 mm as much as possible, and further preferably within 5-7mm, and this distance can also be regarded as the length of one corrugation, and mainly ensures that the corrugated paper has enough number of corrugations per unit length to ensure the supporting capability between the inner and outer sides.

In another embodiment of the outer side protection, a temporary waterproof protection film f0 is attached to the outer side of the waterproof film f, and a film structure of the waterproof film f may be adopted, but it is further preferable that the bonding strength between the inner side of the waterproof film f and the face paper 3 is greater than the bonding strength between the outer side of the waterproof film f and the temporary waterproof protection film f0, and the difference of the bonding strengths may be realized by glue amount of glue or different glue types, or the temporary waterproof protection film f0 may be a preservative film, such as a current household preservative film, which may be directly attached to the outermost side 7 of the cardboard, that is, further to the outside than the waterproof film f, because after the packing box wraps the object, the packing box is usually further wrapped with strong adhesive tape to increase the peripheral wrapping strength or the packing box is wrapped by a binding band to make the structure more compact and firm, when the objects are transported and unpacked, the waterproof film f and the outer side surface of the face paper can be torn, and under the condition that the temporary waterproof protective film f0 exists, only the temporary waterproof protective film f0 can be torn, the waterproof film f cannot be damaged, so that the recycling rate of the paperboard is higher, and the waterproof performance and the protective performance can be further improved.

Two examples are provided below, which the applicant has well realized, and the experimental results are better, the first is the two-sheet corrugated paper-one-core paper paperboard, and the second is the three-sheet corrugated paper-two-core paper paperboard, specifically as follows:

Of course, the above-mentioned preferred mode can be further adopted to improve the performance of the paperboard and the performance of the packing box.

Further, more improvement schemes are provided for the two structures, namely, the two structures can be free from the outer waterproof film f according to requirements, for example, the waterproof effect of short-distance transportation is not high, and the like, so that the waterproof film f is not required to be placed in the hot pressing process. On the other hand, in the two structures, if the temporary waterproof protective film f0 on the outer side of the waterproof film f needs to be added, the temporary waterproof protective film f0 can be attached after the hot pressing process of the two structures is finished, because the adhesive force is large when the temporary waterproof protective film f0 is manufactured together by hot pressing, the temporary waterproof protective film f0 is preferably attached to the outer side of the waterproof film f after the corrugated boards of the two structures with the same foundation are hot-pressed, even glue is not needed, because for example, the temporary waterproof protective film f0 is made of some preservative films with viscosity, and the temporary waterproof protective film f0 only needs to be attached and flattened.
