| titleOfInvention | A kind of micro-crosslinked cationic polyacrylamide flocculant and its preparation method and application |
| abstract | The invention relates to a micro-crosslinked cationic polyacrylamide flocculant and its preparation method and application. The micro-crosslinked cationic polyacrylamide flocculant in the present invention is composed of acrylamide and methacryloyloxyethyldimethylbenzyl ammonium chloride as the main comonomers, and vinylalkoxysilane as the copolymerized cross-linking monomers. Linked monomers are prepared by inverse emulsion free radical polymerization. Among them, vinyl alkoxysilane is used as a copolymerization cross-linking monomer, which can make the polymer molecular chain micro-crosslink during the inverse emulsion polymerization process, and promote the chemical oil displacement agent, crude oil, suspended solids and inorganic salts in the oil recovery sewage. Flocculation and sedimentation of the polymer, etc.; using the method of inverse emulsion free radical polymerization to control the polymerization reaction conditions and the amount of cross-linking monomers added, the molecular weight of the polymer is increased without affecting its water solubility, and the adsorption and bridging of the polymer are achieved. , electric neutralization and hydrophobic association are stronger, and the flocculation separation effect of oily sewage is better. |
