Method.
Background technology
Paper products product indispensable in being people's production and living, especially food-grade packaging paper product and people's health
It is closely bound up.Since the dimensional stability, mechanical property and barrier property of body paper itself are poor, general paper product of packing all is body paper
By special process.Surface coating/sizing is highly developed sheet processing technology, is usually located at the baking of paper machine
Cadre end sprays one layer of glue, through follow-up drying process, in paper and paperboard surface when not being completely dried in page surface
One layer of glued membrane is formed, to achieve the purpose that improve Paper or cardboard surface property.
Currently, the natural polymer Cypres of paper grade (stock) mainly have starch, functional cellulose, animal glue and chitosan
And their modified product.For a long time, native starch due to cheap always in occupation of the head of domestic Cypres
Want status.Native starch is as a kind of high-molecular compound, cheap and enjoy great popularity because of rich reserves, still, gelatinization
Afterwards, mobility is poor, transparent also not satisfactory, and is easy gelation again after cooling down and is not therefore directly used as surface generally and applies
Jelly needs to be modified it.
Common starch Cypres and fiber affinity are relatively poor, and are covered in the starch film on page surface
In the drying process, it is easy to happen rupture, causes that surface strength of paper is low, hair and powder dropping phenomenon is serious in printing process.In recent years
Coming, application study of the nanotechnology in paper surface processing deepens continuously, by Application of micron in paper surface processing,
The performances such as the special optics of paper, mechanics can not only be assigned, the printing performance of paper can also be improved, therefore, by nano-particle
It is added to starch Cypres and has preferable application prospect.
