Description
Technical field
The invention belongs to the preparing technical field of ACID DYES printing gum, be specifically related to a kind of solvent method and prepare hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum.
Background technology
Require during ACID DYES stamp that thickener possesses good acid-proof alkaline, and conventional sodium alginate, carboxymethyl cellulose, carboxymethyl starch thickener all belong to anionic paste, its acid and alkali resistance is very poor, when pH value is lower, in molecule ,-COONa changes-COOH into, cause its viscosity to reduce, produce gelatin phenomenon.In addition the effect of the thickener such as sodium alginate not anticalcium magnesium ion, and the mordant that some acid mordant dyes use is mostly containing heavy metal ion.Convention acidic reactive dye printing paste, mainly based on guar gum and derivative thereof, in recent years, affects by supply-demand relationship, and the price of guar gum significantly rises, and researchers start to seek new ACID DYES printing gum.
Waxy corn starch is almost all made up of amylopectin, compared with other starch, and the expansive force of waxy corn starch, transparency, viscosity is large and filming performance is good, has shear shinning, and its stability of sticking with paste liquid is also fine, easy to digest, not easily aging, be the fabulous raw material of industry.But without processing modified waxy corn starch to pH value, all unstable in temperature and storage, its range of application is limited by very large.The character of modified waxy corn starches, increases its some functional character or introduces new characteristic, makes it more meet commercial Application requirement, and waxy corn starch is all fully utilized in each field.
In prior art, useful dry method and wet processing prepare hydroxypropul starch, the hydroxypropyl carboxy methyl starch of low degree of substitution, and dry method and solvent method prepare carboxymethyl starch.And the hydroxypropyl carboxy methyl starch substitution value of current most of researcher's synthesis is lower, the product hydroxypropyl substitution value of preparation is mostly lower than 0.1, and cold water is insoluble or water-soluble poor, is mainly used in spinning sizing agent, food additives etc.The hydroxypropyl carboxy methyl starch of dry process, impurity in products is more, and reaction efficiency is low, and product need carry out washing impurity-removing with a large amount of organic reagents, complex procedures, and dry process reaction requires higher to reaction condition, otherwise the danger of easily blasting.The hydroxypropyl carboxy methyl starch of Moist chemical synthesis, product substitution value is lower, with the addition of a large amount of salts as swelling inhibitor in reaction system.Wet production condition is also wayward, if it is improper that the conditions such as temperature, starch concentration, catalyst amount control, very easily make product generation gelatin phenomenon, for subsequent technique brings extreme difficulties, and this method reaction efficiency is low, water consumption, power consumption are greatly, simultaneously owing to adding a large amount of salt, also comparatively serious to the corrosion of equipment.
Summary of the invention
Technical problem to be solved by this invention be prepare that ACID DYES printing gum reaction efficiency is low for prior art, complex procedures and the high defect of cost, a kind of preparation method of hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum is provided, utilize solvent method, carry out composite modified to waxy corn starch, cold water-soluble, thickener mobility and saturating net are all better, transparency is higher, meets the requirement of ACID DYES printing gum.
For solving the problems of the technologies described above, the present invention by the following technical solutions: a kind of preparation method of hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum, step is as follows:
A kind of hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum, it is made up of the raw material of following portions by weight: waxy corn starch 95 ~ 105 parts, ethanol water 190 ~ 210 parts, 4 ~ 8 parts, NaOH, expoxy propane 20 ~ 25 parts, monoxone 14 ~ 21 parts; The hydroxypropyl substitution value (MS) of described hydroxypropyl carboxy methyl cornstarch ACID DYES printing gum is 0.30 ~ 0.40, and degree of substitution by carboxymethyl (DS) is 0.2 ~ 0.3.
A preparation method for hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum, step is as follows:
(1) waxy corn starch is joined in ethanol water, be stirred to waxy corn starch and be dispersed in ethanol water, then add NaOH, quaternization 25 ~ 35min under the condition of 20 ~ 30 DEG C;
(2) quaternization adds expoxy propane after terminating, and is warming up to 60 ~ 75 DEG C and carries out etherification reaction 8 ~ 10h after stirring;
(3) etherification reaction is cooled to 45 ~ 55 DEG C after terminating, and then adds monoxone, is warming up to 65 ~ 75 DEG C of reaction 2 ~ 3h after stirring;
(4) reaction is cooled to 25 ~ 35 DEG C after terminating, and regulates pH value of reaction system to neutral with hydrochloric acid, namely obtains hydroxypropyl carboxy methyl waxy corn starch and be applied to ACID DYES stamp after washing, suction filtration, 80 DEG C of oven dry, pulverizing.
In described step (1), the bath raio of waxy corn starch and ethanol water is 1:2.
In described step (1), the mass fraction of ethanol water is 70 ~ 95%.
NaOH distilled water in described step (1) dissolves and is cooled to room temperature.
Hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum is used for ACID DYES stamp.
Beneficial effect of the present invention: (1) raw material of the present invention waxy corn starch is full amylopectin, relative to common starch as: tapioca, wheaten starch and common corn starch etc., waxy corn starch viscosity is high, and anti-aging, transparency is good.Former waxy corn starch not cold water solubles, can not be used for printing gum, must pass through modification.(2) hydroxypropyl waxy corn starch belongs to non-ionic starch analog derivative, forms the ehter bond of strong stability between starch and the hydroxypropyl molar of nonionic, makes hydroxypropul starch have good acid-proof alkaline.And in the hydroxypropyl molar of high substituted degree, introduce more hydrophilic radical hydroxypropyl, reduce the internal hydrogen bond strength of starch granules structure, make it be easy to expand, gelatinization is easy, and cold water-soluble is good, thickener good fluidity, saturating net is also better, and transparency is higher, meets the requirement of printing gum.(3) hydroxypropyl carboxy methyl waxy corn starch is further modification on the basis of preparing hydroxypropyl waxy corn starch, and the carboxymethyl group introducing strong polarity can improve the de-paste of thickener.Product had both possessed the acid-proof alkaline of hydroxypropyl waxy corn starch, possessed again the key property of carboxymethyl waxy corn starch.Hydroxypropyl substitution value (MS) is between 0.30 ~ 0.40, and when degree of substitution by carboxymethyl (DS) is between 0.2 ~ 0.3, hydroxypropyl carboxy methyl waxy corn starch has good resistance to acids and bases, viscosity is high, dissolubility good, good fluidity.(4) when hydroxypropyl carboxy methyl waxy corn starch ACID DYES printing gum of the present invention is used for ACID DYES stamp, tinctorial yield is high, contour sharpness good, de-paste rate is high, feel is good, after stamp, overall target is excellent, may be used for ACID DYES stamp, and starch material is abundant, low price, easily biological-degradable, when environmental problem comes into one's own day by day, this invention meets the requirement of ecological, environmental protective, result of study has also expanded the novelty teabag of converted starch, and industrial value is high.
