Description
Technical field
The present invention relates to a kind of production technology of Type of High Retention Surface Sizing Starch.
Background technology
In order to give paper surface good smoothness and intensity are arranged, people often solve by the way of top sizing modified starch, usually adopt oxidized starch, but this starch and fiber compatibility are poor, when broken copies back, major part enters white-water system, BOD of system and COD value are increased, very harmful to environmental protection, influence system's Zeta potential simultaneously, and then influence paper machine making, and surface strength is also bad.Because cationic starch and anion fiber and filler have very strong suction-operated, can be well by fiber retention, and effectively reduce environmental pollution.Therefore fall over each other to develop the cationic starch that is applicable to paper for surface sizing both at home and abroad.But common cationic starch be because aspects such as its viscosity and stability can not be directly used in top sizing, must be by continuing modification, and to control its viscosity and to guarantee that it sticks with paste the stability of liquid.Reduce the viscosity of cationic starch, common way is that starch is carried out oxidation, and present common use clorox is as oxidant, but the reaction speed of clorox is slow, in oxidizing process, will cause the stripping of great amount of soluble glucide, and produce chloride carcinogen, production and environment are all caused very big influence.Chinese patent literature CN1275991A discloses a kind of " modified starch ", and it produces circuit is oxidation-esterification.Esterification is an anionic reactive, and it can improve characteristics such as gelatinized corn starch fluid viscosity stability, but poor to fiber affinity, and paper plant is formed contaminated wastewater.
Summary of the invention
The technical issues that need to address of the present invention are, overcome the existing deficiency of prior art, provide a kind of technology simple, and starch combines well with being with electronegative fiber, significantly reduces the production technology of the surface sizing starch of paper plant's contaminated wastewater.
The objective of the invention is in order to overcome the deficiency of above-mentioned prior art, adopt polynary sex change technology and unique peracid oxidation technology, shortened the reaction time greatly.Simultaneously can not generate harmful side product, reduce environmental hazard, the more important thing is viscosity stabilization, the surface property excellence makes paper color printing color more bright-coloured, and increases the affinity with paper greatly, almost 100% is retained on the fiber during broken reuse.
The production technology of Type of High Retention Surface Sizing Starch of the present invention, early stage, reaction had two lines: the A route: first CATION etherification reaction-rear oxidation reaction, perhaps B route initial oxidation reaction-back CATION etherification reaction.Two circuits respectively have characteristics, and wherein A route technological parameter on suitability for industrialized production is controlled easily, and the product purity of B route is better.Described CATION etherification reaction is, in starch or last reaction body, add base catalyst and cationic etherifying agent mixture, both mol ratios are 1: 1～3, make by stirring and fully to mix and to be warmed up to 30～90 ℃, reacted 0.5～4 hour, making CATION etherificate base substitution value is 0.010～0.025.Described oxidation reaction is that the mistake acid chemicals of adding starch oven-dry weight 0.1～1% is controlled pH value between 1～4 in last reaction body or starch, under 40～90 ℃, reacts 0.5～5 hour, makes the starch viscosity value of meeting the requirements of, stopped reaction;
2) viscosity stability reaction: add the viscosity stabiliser of starch oven-dry weight 1～5%, regulate pH value to 6～9 simultaneously, under 50～120 ℃, reacted 1～3 hour, make starch carry out crosslinked and esterification; Its series of products viscosity be 5～500mPas (10% solid content, 50 ℃, Brookfield LV, 100rpm).
3) post processing gets product, is about to the product washing, filters, and pneumatic conveying drying, sieving obtains the Type of High Retention Surface Sizing Starch finished product.
Described base catalyst is a kind of in potassium hydroxide, calcium hydroxide, the NaOH or two kinds mixture wherein;
Described cationic etherifying agent is a kind of in 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride, epoxypropyl trimethylammonium chloride ammonium, 2-diethylin ethyl chloride, 4-chloro-2-cyclobutenyl trimethyl ammonium chloride, the Ethylenimine;
The described acid chemicals of crossing is one or both a mixture in Peracetic acid, peroxosulphuric, the peroxide phosphoric acid;
Described viscosity stabiliser is one or both the mixture in vinylacetate, succinyl oxide, the sodium phosphate trimer.
Basic principle of the present invention is the positive electricity substituting group absorption paper pulp fiber that utilizes in the starch molecule, makes that starch still is adsorbed on the fiber when the reuse of papermaking broken, thereby increases paper strength, eliminates the influence of surface sizing starch to wastewater treatment.Utilize super-acid oxidant that starch molecule amount and viscosity are controlled, make starch under higher concentration, all can use, thereby further improve indexs such as the surface strength of paper and smoothness.This positive electricity adsorptivity matches with the high efficiency oxidisability, is innovation part of the present invention.
Product of the present invention can improve surface strength of paper effectively, reduce the consumption of retention, filter aid and waste water flocculant in the slurry simultaneously, have cationic substituent, anion substituent and stable group in the products molecule of the present invention simultaneously, application process is consistent with conventional oxidized starch, and is easy to use.Product of the present invention is particularly useful for the production of paper kinds such as high-grade wood-free paper, electro-photographic paper, art paper, Alhue paper.
Product of the present invention both can adopt wet method, can adopt the preparation of semidry method combined producing tech again.
It is that main raw material carries out derivation process that product of the present invention adopts starch, and starch can be the product that corn, potato, cassava, wheat, rice etc. are made.
Product of the present invention reduces beyond the consumption of retention, filter aid and waste water flocculant in the slurry except improving surface strength of paper, printability and vividness effectively, and it is simple also to have production technology, characteristics such as retention height.
