Description

A kind of waterproof and dampproof corrugated paper and preparation method thereof
Technical field
The present invention relates to field of papermaking, a kind of waterproof and dampproof corrugated paper and preparation method thereof is specifically disclosed.
Background technology
Packaging material is to one of the major function that the protectiveness of built-in amount of substance is packaging, and inner packing is even more to be protected to commodity Shield property plays the role of vital.
Corrugated board is the adherend of a multilayer, it is at least made of one layer of waveform refill layer and a layer paperboard.Corrugation Cardboard has very high mechanical strength, can fall to the collision and falling in by cargo handling process, mainly for the manufacture of carton and The outer packing of delicate articles.
Currently, corrugated board is mainly made of fibrous web, it is easy the shadow by external environmental factors such as humidity, temperature It rings.In the higher environment of some humidity, corrugated board is easy to conduct the moisture of absorption to packaging article, indirectly Reduce the quality of article；And when corrugated board directly meets with water, then it is easy directly to soak packaging article, gives people Bring economic loss.
Invention content
In order to overcome shortcoming and defect existing in the prior art, the purpose of the present invention is to provide waterproof and dampproof watt a kind of Stupefied paper and preparation method thereof.
To achieve the above object, the present invention uses following scheme.
There is a kind of waterproof and dampproof corrugated paper lamination layer structure, composite layer to be followed successively by waterproof layer, high intensity cardboard, fill Layer, waterproof layer are filled with drier in the filled layer.Drier is calcium chloride.
Wherein, waterproof layer is formed by top sizing.Waterproof layer is by 24-31 parts by weight epoxy-polyurethane adhesive, 6-13 weight Part melamine, 13-17 parts by weight of lemon acid sodium, 3-5 parts by weight dimethylethanolamine, 2-5 parts by weight magnesium hydroxide, 6-8 weights Measure part alundum (Al2O3), 3-10 parts by weight of silica, 15-22 parts by weight hydroxypropyls PASELLI EASYGEL, 6-11 parts by weight silicon Sour calcium composition.
Waterproof and dampproof corrugated paper can be by waterproof layer, high intensity cardboard, filled layer and waterproof layer is compound successively forms, specifically For by wood pulp, starch and sugarcane fasciated fiber by weight 10:4:2:1 is mixed, and passes through size degradation, purification, flotation and defibrination Gained slurry is manufactured paper with pulp after processing, obtains high intensity cardboard；By two high intensity cardboards and drier therein is placed through overvoltage It closes, forms filled layer；After high intensity cardboard and filled layer pressing, waterproof layer is formed in top sizing, it is anti-to obtain waterproof Damp corrugated paper.
Wherein, the sugarcane fasciated fiber in high intensity cardboard can improve the tearing toughness of cardboard, with filled with drying After the filled layer of agent is compound, paper can be prevented to be torn because of external stress in all directions.
Surface sizing method is：
(1) melamine, sodium citrate, dimethylethanolamine are mixed first, are added in reaction kettle, deionized water is added, Then magnesium hydroxide and alundum (Al2O3), silica are added, is heated to 160-180 DEG C, soaking time 1-1.5 hours；
(2) hydroxypropyl PASELLI EASYGEL, calcium silicates, 65-85 DEG C of temperature, reaction time 2-3 hour is secondly added；It is eventually adding Epoxy-polyurethane glue stirs, and forms glue；
(3) it is stirred evenly after water repellent agent being added in glue, mixed glue solution is then transported to holding vessel, then will be in holding vessel Glue is delivered directly in sizing applicator, is carried out top sizing, is then dried, and top sizing layer is formed.
The spray pressure of the sizing agent of the sizing applicator is 0.2-0.24Mpa, spraying rate 130-150m/min.
Beneficial effects of the present invention：It is anti-that the waterproof and dampproof corrugated paper and preparation method thereof of the present invention has been obviously improved corrugated paper The moisture-proof ability of water, to improve the safety of corrugation paper wrapper.
Description of the drawings
Fig. 1 is the structural schematic diagram of size applicator of the present invention.
Specific implementation mode
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and attached drawing Bright, the content that embodiment refers to not is limitation of the invention.
The preparation method of waterproof and dampproof corrugated paper is：It is compound successively by waterproof layer, high intensity cardboard, filled layer and waterproof layer Composition, specifically, the high intensity cardboard, by wood pulp, starch and sugarcane fasciated fiber and by weight 10:4:2:1 mixing system At；It is manufactured paper with pulp as the slurry by obtained by after size degradation, purification, flotation and defibrination process, obtains high intensity cardboard；By two high intensity Cardboard and placement drier therein pass through high pressure, form filled layer；After high intensity cardboard and filled layer pressing, applied on surface Glue forms corrugated paper.
Surface sizing method is：
Embodiment one：
(1) 6 parts of melamines, 13 parts of sodium citrates, 5 parts of dimethylethanolamines are mixed by weight first, is added to reaction In kettle, deionized water is added, then adds the 2 parts of magnesium hydroxides, 6 parts of alundum (Al2O3)s, 10 parts of silica of proportional quantity, adds Heat is to 180 DEG C, soaking time 1.5 hours；
