Description
Technical field
The present invention relates to paper industry, and in particular to a kind of ative starch endures adhesive process.
Background technology
Starch is a kind of cheap reproducible natural macromolecular material, nontoxic, easily biological-degradable, in recent years by extensive
Pay attention to, how from depth and range development and application starch resource, it has also become the problem of domestic and foreign scholars common concern.Starch is with it
Wide material sources, cheap, reproducibility is strong, and the advantages that reducing environmental pollution is paid attention to by people.But it is as adhesive stream
Dynamic property and permeability are poor, and directly as adhesive then its performance extreme difference.If by the method pair of physics, chemistry or biology
Starch carries out limited modification, changes its molecular structure and performance, can control the solubility and viscosity of starch, starch molecule
In containing glycosidic bond and be prone to chemical reaction hydroxyl, so starch can and many materials chemically react, this property
Matter is the theoretical foundation of the excellent adhesive of processability.
The application of amylan is very extensive in paper making process, if the cationic starch glue used in slurry is as drying strengthening agent
The dry strength into paper can be improved, the oxidized starch glue or enzyme converted starch glue of top sizing can improve into the water-resistance and print of paper
Brush adaptability, it is coated with the important component that coating starch glue used is coating adhesive.Above-mentioned amylan is by right
Starch milk is boiled to obtain, final to be made as the rise of glue temperature, starch granules are gelatinized during boiling
The starch glue of stable homogeneous.The maximum temperature of glue can reach more than 95 DEG C in amylan preparation process, significantly larger than form sediment
The temperature in use of arogel, therefore in amylan using preceding needing to cool down the glue that high temperature has boiled, generally use it is cold
But mode is that clear water is added into glue, but this mode can destroy the homogeneity of glue so that the bad stability of glue, sternly
The using effect of glue is have impact on again, and during starch boils, starch granules is also easy to produce caking phenomenon when being gelatinized, and influences to form sediment
Arogel quality.
The content of the invention
It is proposed that a kind of ative starch endures colloid system device for the present invention that solves the above problems, reasonable in design, finished product glue meets skill
