Abstract
The invention relates to a polycondensation bead type macroporous resin extraction agent and a preparation method thereof, belonging to the technical field of high polymer materials. The polycondensation bead type macroporous resin extraction agent disclosed by the invention comprises the following raw materials in parts by weight: 15-25 parts of melamine, 35-50 parts of formaldehyde, 5-10 parts of polyphenol, 20-30 parts of solid extraction agent, 5-10 parts of pore-foaming agent, 5-10 parts of distilled water, 300-500 parts of dispersion medium, and 3-5 parts of Barafluro. A plurality of types of solid extraction agents can be embedded in polycondensation bead type macroporous resin disclosed by the invention; melamine is directly used as the synthesis raw material of the polycondensation bead type macroporous resin extraction agent disclosed by the invention; the mechanical strength of resin is effectively increased; the service life of the resin extraction agent is increased; in addition, due to application of the pore-foaming agent, the prepared resin extraction agent has macroporous property; and the extraction efficiency of the resin extraction agent is increased.
Description
technical field [0001] The invention relates to a resin extractant and a preparation method thereof. More specifically, the invention relates to a polycondensation bead-shaped macroporous resin extractant and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Polycondensation ion exchange resin is a kind of ion exchange functional polymer material that was developed earlier and has a wide range of applications. At present, it has been widely used in water treatment, pharmaceutical industry, food industry and other industries. [0003] This type of resin is prepared by polycondensation reaction process as the main preparation method. The earlier polycondensation resins were first made into block polymers by bulk polymerization, and then crushed and sieved to obtain amorphous particles. The resin obtained by this preparation method is not bead-like in shape and has poor hydraulic performance, so it is difficult ...
