Description
Technical field
The present invention relates to packing boards, it relates in particular to a kind of preparation method of bond for corrugated board, corrugated paper
The dry solution of plate adhesive, and use corrugated board made from the binder and preparation method thereof.
Background technique
In general, corrugated board is a kind of packaging material that dosage is very big in packaging industry, it by least one layer of corrugated paper and
One layer of boxboard is bonded using adhesive, and common adhesive has sodium silicate, high molecular emulsion and starch.Sodium silicate bonding
Carton moisture-proof made from agent, pressure-resistant performance is poor and has corrosion.High molecular emulsion binder performance is preferable, but cost is too high, and not
It is degradable.Starch is a kind of natural carbohydrate, and amylum adhesive is with resourceful, manufacture craft is easy, to environment
Friendly, the advantages that cost is relatively low, the adhesive of corrugated paper gluing at present is mostly amylum adhesive.
The water content of amylum adhesive is very high, in adhering and solidifying, needs the moisture evaporation by the overwhelming majority to fall, using steaming
Each group of heating plate of the dryer of vapour heating is designed with pressure regulator valve, for being adjusted into the steam pressure of heating plate, makes to dry
Machine reaches suitable temperature, has not only guaranteed to paste liquid solidification, but also guarantee that the corrugated board water content of final molding is moderate.This just need compared with
High drying temperature and longer drying time, consume a large amount of energy.However, this adhesive made from conventional method
Rate of drying is excessively slow, so that the corrugated board production period is longer.

Specific embodiment
Hereinafter, by conjunction with exemplary embodiment come the corrugated board that the present invention will be described in detail and preparation method thereof, watt
The preparation method of corrugated paper board adhesive and the dry solution of bond for corrugated board.
In an exemplary embodiment of the present invention, the preparation method of bond for corrugated board can be real by lower step
It is existing:
Firstly, preparing carrier starch paste.
Specifically, the first cornstarch is added in 30~40 DEG C of the first water body, stirs and be added soda bath, with
Afterwards, clipped processing obtains carrier starch paste.Wherein, the mass ratio of the first water body, the first cornstarch and soda bath can be with
For 12~18:1~1.5:1~1.5.Further, the first water body, the first cornstarch, soda bath mass ratio can be 14
~16:1.2~1.4:1.1~1.3.Soda bath can be water-soluble for sodium hydroxide of the mass fraction in 25~40% ranges
Liquid.Caustic soda plays the role of reduction starch gelatinization temperature, adjusts adhesive viscosities.If amount of caustic soda is very few, gelatinization is insufficient, viscosity
It is too big；If amount of caustic soda is excessive, excessively, viscosity is too small for gelatinization.Therefore, caustic soda and the first cornstarch should be in said ratio ranges
It is interior.First water body can be pure water, and the temperature of the first water body can further be 32~38 DEG C.
Then, it is pasted using carrier starch, forms bond for corrugated board.
Specifically, it is gradually added into the second cornstarch in 30~40 DEG C of the second water body, then is gradually added into the load
Body gelatinized corn starch and dry solution, are sufficiently stirred.Then, borax is added, carries out shear treatment, obtains bond for corrugated board.Its
In, the second water body, the second cornstarch, carrier starch paste, dry solution and borax mass ratio can be 25~35:10~15:
20~25:0.5~3:0.1~0.3.Further, the second water body, the second cornstarch, carrier starch paste, dry solution and borax
Mass ratio can be 28~32:12~14:22~24:0.8~2.5:0.15~0.25.Borax plays crosslinking, tackifying effect, increases
The robustness for adding binder film promotes the bonding force of adhesive, if borax dosage is very few, crosslinking degree is inadequate, and cohesive force is poor, if
Borax dosage is excessive, cause crosslinking excessively, the easy hanging wire of gluing, in addition can lose flowability and viscosity.Second water body can be pure
Water purification, the temperature of the second water body can further be 32~38 DEG C.
Wherein, dry solution in parts by mass can by 25~35 parts cyanurotriamide modified urea resin, 25~35 parts
Zeolite powder and 35~45 parts of sodium bentonite are constituted.Further, dry solution can be by 28~32 parts of melamine modified urea
Urea formaldehyde, 27~33 parts of zeolite powder and 38~42 parts of sodium bentonite are constituted.The effect of dry solution includes accelerating adhesive
Rate of drying.In the ingredient of dry solution, cyanurotriamide modified urea resin film forming speed is fast, can the rapidly shape on paper
At a tunic, prevent water to paper internal penetration.Zeolite is a kind of with connected pore channel, the hydrous alumino silicates mine constructed in rack-like
Object is a kind of porous material, is conducive to form a large amount of microcellular structure inside adhesive, has the function of promoting water evaporation.Sodium base
Bentonitic water absorption is big, can increase the solid content of adhesive, meanwhile, the positive charge of adsorption and negatively charged paper
Fiber forms bridge linking effect, can effectively block the hole on paper fiber surface, hinders water in adhesive to paper internal penetration.This
Three kinds of ingredients can effectively improve the evaporation rate of water in adhesive, and synergy can be played when being used in conjunction with.If rapid-curing cutback
Agent dosage is very few, cannot play the role of due raising rate of drying, if dry solution dosage is excessive, will cause the viscous of adhesive
Degree is significantly increased, is glued the defects of uneven and Poor cohesion, and therefore, the dosage of dry solution should compare range in above-mentioned quality
It is interior.

Device, then it is gradually added into the soda bath of 35kg, it carries out (10000 revs/min) of high speed shear and handles 12 minutes, obtain carrier shallow lake
Paste mixing.
(2) water of 705kg is added in main body tank, is heated to 35 DEG C, is subsequently added into the cornstarch of 285kg, starting is stirred
Mix device, then be gradually added into the 520kg carrier starch paste, dry solution 45kg of step (1) preparation, be sufficiently stirred 8 minutes, finally plus
Enter borax 5kg, carries out (12000 revs/min) of high speed shear and handle 15 minutes, obtain adhesive.
In another exemplary embodiment of the invention, corrugated board can be by least one layer of corrugated paper and at least one layer
Boxboard use as it is above it is each it is exemplary described in bond for corrugated board bond.
In another exemplary embodiment of the invention, the preparation method of corrugated board can be with are as follows: using as each above
It is a it is exemplary described in bond for corrugated board at least one layer of corrugated paper and at least one layer of boxboard are bonded；So
Afterwards, it is dried at 120~140 DEG C.The time of drying can be 5~20 seconds.
Corrugated board is prepared using the adhesive of conventional corrugated board amylum adhesive and three parts of examples 2 respectively.Through
Detection, respective drying temperature and time are as follows: respectively
| Number | Drying temperature/DEG C | Drying time/second |
| Comparative example | 160 | 18 |
| 1 | 140 | 12 |
| 2 | 130 | 15 |
| 3 | 120 | 17 |
Through analyzing, the present invention reduces moisture, and can have from increase solid content is conducive to by improving the formula of adhesive
