| titleOfInvention | A branched cationic polyacrylamide flocculant and its preparation method and application |
| abstract | The invention provides a branched cationic polyacrylamide flocculant and a preparation method and application thereof. The flocculant of the invention uses tetramethylol glycoluril as branching agent, acrylamide and methacryloyloxyethyltrimethylammonium chloride as comonomers, and is prepared by graft copolymerization. The preparation method of the invention is simple, the prepared flocculant has a specific branched structure, the chain length and chain entanglement are reduced, and the flocculant has lower viscosity, better solubility and higher utilization rate of cations, and a large amount of internal empty space. The cavity is conducive to the adsorption and sweeping of suspended particles in oily sewage, which can overcome many defects of linear flocculants, and show excellent flocculation performance and oil removal effect. |
