| titleOfInvention | Method for preparing composite water-retaining agent by taking oil shale semi-coke and clay mineral as inorganic components |
| abstract | The invention provides a method for preparing a composite water-retaining agent by taking oil shale semi-coke and clay mineral as mixed inorganic components, which comprises the steps of mixing the semi-coke and the clay mineral, adding the mixture into a natural polymer solution, and fully stirring to obtain a uniform dispersion liquid; adding an initiator for activation for 1-15 min; then dropwise adding a mixed solution of a polymerizable monomer and a crosslinking agent, and carrying out nitrogen protection and 50-100% mixing o And C, performing heat preservation polymerization for 1-6 h, drying and crushing to obtain the composite water-retaining agent. According to the invention, the oil shale semi-coke and clay mineral are used as mixed inorganic components to prepare the composite water-retaining agent, so that the production cost of the water-retaining agent can be obviously reduced, and the water absorption performance of the composite water-retaining agent can be further improved; the water absorption rate of the prepared composite water-retaining agent is obviously higher than that of a water-retaining agent prepared from oil shale semi-coke and clay minerals, and in addition, the composite water-retaining agent has good salt resistance and can be widely applied to water-saving agriculture and ecological environment restoration. |
