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