Abstract

The invention relates to magnetic resin microspheres and a preparation method thereof, belonging to the technical field of high molecular materials. The magnetic resin microspheres comprise the following raw materials by weight parts: 5-10 parts of acrylonitrile, 10-20 parts of styrene, 50-70 parts of divinyl benzene, 20-30 parts of triallyl isocyanurate, 10-19 parts of methyl acrylate, 50-60 parts of gasoline, 40-50 parts of methylbenzene, 1-2 parts of dibenzoyl peroxide, 10-20 parts of nano Fe3O4, 400-600 parts of de-ionized water, 50-60 parts of calcium oxide, 20-30 parts of sodium chloride and 1-2 parts of polyvinyl alcohol. According to the preparation method, a suspension polymerization process is adopted, polymerization monomers are selected from styrene, acrylonitrile and the like, a cross-linking agent is selected from divinyl benzene and triallyl isocyanurate, and magnetic particles are nano Fe3O4 particles, so that the magnetic property is improved, separation is facilitated, and no residues are generated; the magnetic resin microspheres are rich in function and suitable for various fields.

Description

technical field [0001] The invention relates to a resin and a preparation method thereof, more specifically, the invention relates to a magnetic resin microsphere and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Magnetic polymer microspheres are composed of magnetic inorganic particles (iron, cobalt, nickel or their oxides, generally Fe 3 o 4 Mostly) is a kind of high molecular polymer with special structure compounded with high molecular substances. Magnetic polymer microspheres are easily separated under an external magnetic field, and specific functional groups (such as —COOH, —NH 2 ,—SH,—OH, etc.). Therefore, magnetic polymer microspheres are used in many aspects such as enzyme immobilization, DNA separation, drug carrier and so on. According to the formation structure of magnetic polymer microspheres, we can divide them into core-shell structure polymer microspheres and sandwich structure polymer...
