Description
Technical field
The present invention relates to corrugated board technical field, specifically a kind of hot melt composite water-proof corrugated board and its preparation
Method.
Background technique
Corrugated case has that light weight, cost performance are high, structural behaviour is good, foldable, printing adaptability is strong, environmental protection is recyclable
And the advantages that suitable automatic packaging operation, becomes common so far and does not wane, sends out in the field of circulation using more and more extensive
Swift and violent paper packaging container is opened up, most important a kind of packaged form in modern packaging is become.
In traditional handicraft corrugated board processing mainly using each layer body paper of water soluble starch glue laminating (facial tissue, watt paper,
In paper), amylan is easy mouldy there are non-watertight, and needs the moisture in a large amount of thermal energy drying water soluble starch glue, that is, needs
High temperature hot plate dries it, leads to the problem of a large amount of energy consumptions.Often occur causing to produce because moisture control is not in place simultaneously
There are various quality problems in the cardboard come.Using the corrugated board of starch glue laminating, do not have waterproof performance, fitting part is once
Dampness, it is easy to be layered degumming, the structure of carton caused thoroughly to be destroyed, there is be collapsed, collapse case phenomena such as, greatly influence paper
Every physical strength index of case；Even if later period paperboard surface carries out water-proofing treatment, water entrance is still suffered from edge notches
Cause to be layered.If carrying out edge sealing by carton waxdip, low efficiency and at high cost, wax can have pollution to food.
There are many method of the water-proofing treatment of corrugated board surface progress at present, for example, 1. on corrugated board process line,
It installs a painting liquid bath additional, directly applies one layer using wax and rosin as " the water-sprinkling agent " of main material on the surface of cardboard；2. using coating machine
Coating, on entire volume body paper surface, applies the acrylic type water-proof coating (food-grade) of upper inlet, but after coating waterproofing agent, maximum
Problem is the water-based printing and patch adhesive label in later period；Fixed can the using of high-volume, shipping mark applies again after preprinting in this way,
But small batch or printing shipping mark change more waterproof carton and just do not have this condition.At present through the corrugated paper of water-proofing treatment
The waterproof effect of case is limited, and inner and outer surfaces have the corrugated case application of waterproof effect even more less and few, often by some lifes
The limitation of production condition and requirement, can not widespread adoption.
Chinese patent CN102975458A discloses the corrugated board and its manufacturing method of a kind of dry adhered, comprising: one
A sandwich layer is shaped to wavy；One surface layer, one of surface lamination are coated with a film layer；One bottom, one of them
Surface lamination is coated with another film layer；Processing program through pressing again makes surface layer and bottom be pressed on the two sides of sandwich layer respectively,
To complete the manufactured goods of corrugated board.The invention is bonded although without using adhesive agent using surface layer, bottom, sandwich layer simultaneously
Mode, bonding effect is limited, and quality is difficult to control, using the modes such as high frequency or ultrasonic wave replace conventional high-temperature drying stream
Journey, and film layer is PE material (polyethylene polyethylene), non-refractory is not suitable for existing corrugated paper board production line, no
It is suitable for that volume facility metaplasia produces.
Therefore, a kind of waterproof corrugated board and preparation method thereof how is provided, to realize that corrugated board is with higher anti-
It is aqueous can, surface and the equal waterproof of adhesive layer, and printable surface do not need that starch glue is added in process of manufacture, be not necessarily to
The drying of hot plate high temperature, reduces energy waste, is current those skilled in the art technical problem urgently to be resolved.
Summary of the invention
In view of this, the application's is designed to provide a kind of hot melt composite water-proof corrugated board and preparation method thereof, with
Corrugated board waterproof performance with higher, surface and the equal waterproof of adhesive layer, and printable surface are realized, in process of manufacture
It does not need that starch glue is added, is dried without hot plate high temperature, reduce energy waste.
In order to achieve the above object, the application provides the following technical solutions.
A kind of hot melt composite water-proof corrugated board, including facial tissue, watt paper and inner paper, the inner surface of the facial tissue and inner paper
One layer of polymeric membrane of lamination is distinguished in outer surface, and the polymeric membrane is between facial tissue and watt paper, between inner paper and watt paper；Its
Described in the inner surface of facial tissue be the face that be bonded with described watt of paper, what the outer surface of the inner paper was as bonded with described watt of paper
Face.
Preferably, the polymeric membrane have low-temperature heat-sealing performance, the polymeric membrane with a thickness of 15~20g/m2。
Preferably, the polymeric membrane is ethene copolymer.
Preferably, the polymeric membrane is LDPE-g-MAH (grafted low density polyethylene maleic anhydride), POE-g-MAH
(ethylene octene hydrocarbon copolymer grafted maleic anhydride), EVA (ethylene-vinyl acetate copolymer), EMA (ethylene maleic acid acid anhydride copolymerization
Object) and EAA (ethylene acrylic acid co polymer) in one or more of any combination.
Preferably, described watt of paper is extrusion coating paper, and the extrusion coating paper includes original paper layer, waterproof layer, and the waterproof layer is PET film
Or PP film.
Preferably, the corrugated board further includes middle paper, and described watt of paper includes first watt of paper and second watt of paper, and described first
Watt paper is between the facial tissue and middle paper, and for second watt of paper between the inner paper and middle paper, the middle paper is located at the
Between one watt of paper and second watt of paper.
Preferably, the waterproof layer includes the first waterproof layer and the second waterproof layer, first waterproof layer and the second waterproof
Layer is located at the original paper layer two sides.
Preferably, the compound one layer of appearance facial mask in the outer surface of the facial tissue, the appearance facial mask are PET film or PP film, institute
