Abstract
The application belongs to the field of water and mud treatment agents, and discloses a hydrophobic modified soybean globulin-based flocculant and a preparation method and application thereof. The preparation method comprises the following steps: dissociating soybean protein subunits under alkaline conditions and nitrogen protection; adding pre-emulsified octenyl succinic anhydride or dodecyl glycidyl ether to perform grafting reaction; adjusting pH to terminate the reaction and aging; and washing and drying to obtain the product. The flocculant has a hydrophobic association three-dimensional network structure, can efficiently capture particles in water, and can produce self-extrusion drainage effect in mud dewatering, so that the dewatering efficiency is high and the environment is friendly, and the flocculant is suitable for high-turbidity water purification and building mud dewatering.
