| titleOfInvention | Preparation method of fluorine-containing thickening agent capable of thickening hydrochloric acid solution |
| abstract | The invention provides a preparation method of a fluorine-containing thickening agent capable of thickening a hydrochloric acid solution, which comprises the following steps: 1) dissolving acrylamide, a fluorine-containing monomer and a cationic monomer in water to obtain a first solution; 2) adding a complexing agent, an activating agent, an oxidizing agent and an initiator into the first solution, uniformly mixing, and then carrying out a first reaction to obtain a second solution; 3) heating and then carrying out a second reaction to obtain a polymer jelly; 4) and (3) granulating, drying, crushing and sieving the polymer jelly to obtain the thickening agent in a dry powder state. The acid liquor system containing the thickening agent solves the problems of low viscosity, large filtration loss, short action distance, difficult communication with remote reservoirs and the like of the conventional acid liquor at high temperature. |
