Water-reducing compound modified starch thickener and preparation method and application thereof
The invention provides a water-reducing compound modified starch thickener and a preparation method and application thereof. According to the water-reducing compound modified starch thickener provided by the invention, after maltodextrin molecules are subjected to etherifying modification, sulfonic acid groups are introduced. The water-reducing compound modified starch thickener provided by the invention has a good thickening effect on concrete so as to obviously improve workability of concrete, also has a certain water reducing effect and shows good adaptability to a water reducing agent, an air entraining admixture, a retarder and the like.
