Description

Seal the cardboard of side
Technical field
The utility model be it is a kind of mixing hot melt adhesive and wax to seal the cardboard of side, espespecially in the clearance space of cardboard In, a bonding material and a sealing material are sequentially filled from inside to outside, to form an edge sealing structure of tool water proofing property, the bonding material Material and sealing material are all mixed by hot melt adhesive and wax, but the stickiness of the bonding material is more than the sealing material, can form tool The bonding coat of multiple holes, the sealing material can then fill up the hole on the bonding coat, to form water seal, prevent aqueous vapor from soaking The wet cardboard.
Background technology
Corrugated paper (Corrugated Fiberboard, also known as corrugated board, leatheroid) is a kind of using extremely wide paper Material, its structure are between two layer planes " plane materiel " (being mostly brown paper), one layer wavy " core " are set, due to overall knot The volume for having 60%~70% in structure is hollow, therefore has good damping performance, is very suitable for being applied to make carton.This Outside, corrugated case (Corrugated box) still have low cost, easy processing, easy to print, recyclable, empty weight it is gently etc. excellent Good feature, therefore, it has also become at present in shipping carton main material.
Although corrugated case has above-mentioned many merits, it also there are and applied the defects of upper, that is, lack " moisture resistance ", one Denier corrugated case is adsorbed onto aqueous vapor, its structural strength will be reduced quickly, and be easy to rupture.Due to transporting seafood or life During fresh food and other items, cargo surfaces can more or less have water stain or aqueous vapor, and general corrugated case heat insulating ability is not high, When shipping time is longer, seafood more can be because of gradually rising again, or because temperature difference inside and outside carton, and in the surfaces externally and internally of carton Condense out more water droplets, cause corrugated case after destination is sent to, shipping personnel one move the corrugated case, and corrugated case is Easily because structural strength has been greatly reduced, and rupture (collapse) in the handling process, cause goods inside be scattered and Go out.
In order to solve the problems, such as foregoing " moisture resistance ", traditional solution method, is coated with the medial surface of corrugated case Coating of wax liquid (wax), to form waterproof layer, increase moisture resistance, but this practice and imperfection, refering to Figure 1, being one watt (corrugated board 1 can pass through equivalent the structure diagram of corrugated paper board 1, form carton, therefore herein only with partial schematic diagram, illustrate watt The structure of corrugated paper board 1), which includes two plane materiels 11,12 and a core 13, wherein can on the lateral surface of a plane materiel 11 Be coated with wax liquor, form waterproof layer 14, with after the corrugated board 1 is folded into carton, the waterproof layer 14 can prevent it is water stain or Aqueous vapor soaks the corrugated board 1.
However, since the core 13 in the corrugated board 1 is not protected by wax liquor, it is located at one in the corrugated case When in high humidity environment (high moisture environments), aqueous vapor still can penetrate into core from the side of the corrugated board 1 The medial surface of material 13 or plane materiel 11,12, destroys the structural strength of the corrugated board 1.Refering to Figure 1, on the corrugated board 1 Parallel to its stupefied a side to (that is, 13 wavy extending direction of core) formed with (the also known as plane of structure of a side opening 101 Cross section), and on the corrugated board 1 perpendicular to its it is stupefied to another side then formed with one it is stupefied to opening 102 ( Claim vertical face longitudinal section), by schema it can be seen that, do not possess in the side openings 101 plane (and It is to be formed by the wavy gap separated of core 13), therefore, wax liquor may be coated with, to form waterproof layer 14.
Further, since the core 13 can still adsorb wax liquor, therefore, even if dealer is coated with the side openings 101 reluctantly Wax liquor, wax liquor can be also penetrated into the core 13, and waterproof layer can not be formed in side openings 101, this means, " side openings 101 can form waterproof loophole " the problem of, and the mode of " coating wax liquor " can not be merely passed through to solve.At present, if dealer has The demand of the corrugated case of high moisture-proof is produced, then dealer must immerse monoblock corrugated board 1 in (submerge) wax liquor, make The corrugated board 1 adsorbs enough wax liquors, and the beginning can ensure that aqueous vapor will not soak corrugated board 1 by side openings 101.However, such as This one, the production cost (at least increasing by twice) of corrugated case can not only be significantly increased, and weight can also be substantially increased and (about increase Add 50%), and do not meet the demand of dealer.
From preceding description, corrugated case at present, it is difficult to while " moisture resistance " and " material cost " is taken into account, if being intended to Kind forms waterproof layer on carton, then needs to use excessive wax, and can increase weight, not a suitable solution. In addition, the inventor of the utility model still has found, even if waterproof layer is formed through wax liquor, but since wax liquor does not have " heat insulating ability ", Therefore, when transporting cargo, still there is the problem of in insulation.Such as:In long-distance transport, seafood, fresh food are (such as:Meat, Dairy produce) can because temperature rises and corruption (that is, cold insulation deficiency) and if red wine, flowers or medicine and other items, either It is too high or too low for temperature, it can all have a negative impact and (that is, lack constant temperature effect).
Therefore, how to be improved for existing corrugated board 1, design it is a kind of easy to implement and can control raw material into This mode, closes the side openings 101 of the corrugated board 1, effectively to lift its moisture resistance, meanwhile, it can still be lifted at the same time The heat insulating ability of corrugated board 1, even improve the functions such as sound insulation, impact resistance, becomes the utility model and desires most ardently solution herein Important topic.
