| titleOfInvention | The preparation method of porous magnetic polystyrene microsphere |
| abstract | The invention discloses a kind of preparation method of porous magnetic polystyrene microsphere, (1) is by dry Fe 3 O 4 Magnetic nano-particle joins in ethanol water, after ultrasonic processing, adds VTES, then proceeds in the lump in reactor, under nitrogen protection, constant temperature stir ageing, product through washing, vacuum drying, pulverize; (2) get powder and the benzoyl peroxide mixing that step (1) obtains, add in the styrene that contains pore-foaming agent and crosslinking agent ultrasonic processing; (3) by polyvinylpyrrolidone and lauryl sodium sulfate ultrasonic dissolution in water; (4) liquid step (2) being obtained joins in the liquid that step (3) obtains, ultrasonic processing, the mixture obtaining is poured in reactor, and the reaction of intensification condensing reflux, obtains suspension, wash through magnet magnetic separating alcohol, magnetic separates pure water washing again, and brown color powdered product is ground to obtain in vacuum drying, then Soxhlet extracting, last vacuum drying, to obtain final product. |
