| titleOfInvention | Preparation method of water-absorbing and oil-absorbing bifunctional resin |
| abstract | The invention relates to a preparation method of water-absorbing and oil-absorbing bifunctional resin. The method comprises the following steps: 1) first adding an emulsifier and an oil-soluble cross-linker into an oil phase monomer, stirring evenly, and introducing nitrogen gas for a few minutes to obtain an oil phase; 2) weighing an aqueous phase monomer, and preparing an aqueous solution to obtain a water phase; 3) dropwise adding the water phase to the oil phase to obtain an emulsion; and 4 ) dropwise adding an solution prepared from an initiator to the emulsion, continuing to stir for 20-60 min until a stable state of the emulsion, placing the emulsion in an environment at 20-50 DEG C for polymerization, reacting for 24 h, and treating the products by vacuum drying to a constant weight, so as to obtain the water-absorbing and oil-absorbing bifunctional resin. The preparation method provided by the invention has simple process, safe operation and mild reaction conditions; and the obtained resin has water-absorbing and oil-absorbing double functions and strong repeated water absorption ability, can meet needs in a variety of areas, and has broad market prospects and potential use value. |
