Abstract
The Starch Adhesive that the invention discloses the quick oxidation style of a kind of cold mixed starch and produce in this way.Starch is added water be made into and carry out gelatinization behind the suspension liquid handle under alkaline condition, carry out oxide treatment again under sufficient illumination condition, can finish oxidation of starch and handle in tens of minutes, reduce the production time and the cost of Starch Adhesive, quality product is also better.
Description
The present invention relates to a kind of cold tackiness agent of joining quick method for oxidation and making of starch with this method for oxidation.
At present, whether the method for oxidation of starch conversion divides by heating, and has heat to join method and cold two kinds of the methods of joining, and it is better that heat is joined the quality of method, but need consumption of calorie, production cost height.The cold method of joining generally is to carry out gelatinization processing and oxide treatment at acidic conditions, but its long reaction time (needs a few hours, even tens of hours) thus production efficiency low, if adopt potassium permanganate oxidation method, starch after the oxidation is had+color of 4 valency mn ions and influence its use range, and production cost is also higher, thereby causes adopting the cost of the Starch Adhesive that aforesaid method produces higher, and the production cycle is longer.
Task of the present invention will provide a kind of consumption heat energy seldom exactly, and the reaction times is short, the starch oxidation method that production cost is low, and the Starch Adhesive that utilizes this method to produce.
Task of the present invention is to solve like this: earlier starch is added water and be made into 40%～55% suspension liquid, carrying out gelatinization then under the alkaline condition of the solution that contains sodium hydroxide handles, after treating the complete gelatinization of starch, under competent illumination condition, add initiator ammonium persulfate solution or copperas solution and oxidants hydrogen peroxide or clorox more while stirring and carry out oxide treatment.The concentration of the sodium hydroxide solution that adds is preferably 6%～15%, and the concentration of the ammonium persulfate solution of adding is preferably 8%～20%, if add copperas solution, its concentration is preferably 10%～30%.Illumination condition shines the illumination setting that is obtained by the incandescent light that every usefulness 50 gram starch materials need obtain with 100 watts in the distance of 30cm, and various raw material consumptions are counted by % weight:
Starch 87～96, ammonium persulphate 0.5～3.5,
Sodium hydroxide 1.2～5.2, hydrogen peroxide 1.0～4.3.
