Abstract

The invention relates to a magnetic resin microsphere and a preparation method thereof, belonging to the technical field of polymer materials. The magnetic resin microspheres of the present invention include the following raw materials in parts by weight: 5-10 parts of acrylonitrile, 10-20 parts of styrene, 50-70 parts of divinylbenzene, and 20-parts of triallyl isocyanurate 30 parts, 10-19 parts of methyl acrylate, 50-60 parts of gasoline, 40-50 parts of toluene, 1-2 parts of diphenyl peroxide, 10-20 parts of nano Fe3O4, 400-600 parts of deionized water, calcium oxide 50‑60 parts, 20‑30 parts of sodium chloride, 1‑2 parts of polyvinyl alcohol. The present invention adopts suspension polymerization, the polymerization monomer is selected from styrene, acrylonitrile, etc., the crosslinking agent is selected from divinylbenzene and triallyl isocyanurate, and the magnetic particles are nano-Fe3O4 particles, which enhance the magnetic properties and facilitate separation. There will be no residue, and the magnetic resin microspheres have rich functions and are 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...
