Description
Technical field
The present invention relates to field of papermaking, more particularly to a kind of preparation side with the biological size-press starch added in paper making pulps
Method.
Background technology
It is main that the water repelling property of page and superficiality are improved using plasm-glue-blending and top sizing in paper industry
Energy.The sizing agent of existing in the market is mainly oxidized starch, cationic starch, anionic starch and enzymatic starch etc..Enzymolysis forms sediment
Powder due to simple production process, production cost is low, easy to use etc. to be widely used.But because it reacts influence factor
More unmanageable enzyme digestion reaction makes the stable sizing material of property, and main influence factor is that enzymatic activity influences to cause mobility
(viscosity) changes, the unstable dextrin for causing to be formed after amylase shearing starch of reaction condition and the ion knot in production technology water
Conjunction has color reaction so as to influence sizing efficiency, and it is therefore necessary to develop a kind of enzymatic starch for producing stabilization to be glued as biology
Starch.
The content of the invention
The invention provides a kind of preparation method of biological size-press starch, a kind of preparation of biological size-press starch of the invention
Method, which can be reacted to rapidly after Expected Results, to be stopped reaction keeping mobility to stablize unchanged, and is passed through and adjusted stable surge combination
In two components ratio eliminate color reaction.
Technical scheme provided by the invention is：A kind of preparation method of biological size-press starch, is prepared by following methods：
Step 1：The alpha-amylase spraying of 0.05-0.07 parts by weight is added in the tapioca of 99 parts by weight；
Step 2：The copper sulphate of 0.005-0.015 parts by weight is added in the mixture that step 1 obtains；
Step 3：The stable surge combination adipic acid-sodium sulfite of the enzyme reaction of 0.5-0.8 parts by weight is added into step 2 to obtain
To mixture in, under conditions of 54-56 DEG C, stirring reaction produces for a period of time.
In the preparation method of above-mentioned biological size-press starch, the stable surge combination adipic acid-sulfurous of described enzyme reaction
Sour sodium is made up of 0.2mol/L solution of adipic acid and 0.2mol/L sodium sulfite solution, and solution of adipic acid and sodium sulfite are molten
The weight ratio of liquid is 1:2-3.
The present invention after being reacted to Expected Results rapidly after adopting the above technical scheme, compared with prior art, stop instead
Mobility should be kept to stablize unchanged, and the ratio by adjusting two components in stable surge combination eliminates color reaction.
