Description
Technical field
The present invention relates to a kind of paper grade (stock) composite modified starch, belong to pulp technology for making paper.
Background technology
Converted starch refers on the basis of the inherent characteristic that native starch has, to improve the performance of starch, expanding
Its range of application, using physics, chemistry or enzymatic treatment, new functional group is introduced on starch molecule or to change starch molecule big
Small and starch granular property, so as to change the natural characteristic of starch（Such as：Gelatinization point, thermoviscosity and its stability, freeze-thaw stability
Property, gel force, film forming, the transparency etc.）, make it more suitable for the requirement of certain application.It is this by secondary operation, change property
The starch of matter is referred to as converted starch.
The denaturation purpose of converted starch：One is to adapt to the requirement of various commercial Applications.Such as：High-temperature technology（Can is killed
Bacterium）It is required that starch high temperature viscosity good stability, frozen food requirement starch freeze thawing good stability, the fruit jelly food requirement transparency
Good, good film-forming property etc..Two is, in order to open up the new application of starch, to expand range of application.Such as：Starch is used in weaving；Ethoxy
Starch, hydroxypropul starch replace blood plasma；Crosslinked starch high replaces surgical glove talcum powder etc..
Converted starch is added in paper, paper strength can be significantly improved, there is preferable retention, filtrating aid function, improve paper
Locomotive speed, reduces white water consistency, reduces pollution, and reducing energy consumption breaks end in reduction paper-making process.Existing paper grade (stock) converted starch
With following weak point：1) converted starch its own charge influences the current potential of paper pulp, positive electricity phenomenon occurs, so that shadow
Ring using effect；2) fiber, filler carry negative charge, are mutually adsorbed by electrostatic attraction between yin, yang electric charge, produce flocculation,
Influence the evenness and intensity of page；3) can not with anionic additive (such as fluorescent whitening agent, Dispersed Anionic Rosin Size, it is cloudy from
Son etc.) while using；4）Some careless plasmoid, secondary stock, ground wood pulps, miscellaneous anion chemical substance are more, can disturb cationic starch
Application effect.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art part, there is provided a kind of paper grade (stock) composite modified starch.
Paper grade (stock) composite modified starch of the invention, is made by the following method：
1）A certain amount of cassava ative starch is added to the water, is stirred continuously to form starch suspension；
2）Regulation pH value adds POCl3 to 11, carries out cross-linking reaction；
3）Regulation pH value adds liquor natrii hypochloritis to carry out oxidation reaction to 9；
4）Regulation pH value adds 2,3- epoxypropyltrimethylchloride chlorides to carry out cationoid reaction to 11；
5）Hydrochloric acid is added dropwise, is neutralized；
6）Washing and drying obtains finished product.
Described step 2）In, the temperature of cross-linking reaction is 30 degree, and the reaction time is 1-1.5h.
Described step 3）In, the temperature of oxidation reaction is 37 degree, and the reaction time is 2-3h.
Described step 4）In, the temperature of cationoid reaction is 20 degree, and the reaction time is 14-16h.
Paper grade (stock) composite modified starch of the invention, by aoxidizing and being crosslinked, balances yin, yang electric charge, can be with each addition
Agent, such as fluorescent whitening agent, Dispersed Anionic Rosin Size are used simultaneously, and suitable for the paper production of various paper pulp.
