Abstract

The invention discloses a magnetic super-hydrophobic polystyrene-based porous material preparation method, which comprises: carrying out a polymerization reaction on a styrene monomer, an epoxy group-containing alkene monomer, amino-modified Fe4O3 and a cross-linking agent at 40-80 DEG C for 4-24 h under the action of an initiator, water and an emulsifier to obtain the magnetic super-hydrophobic polystyrene-based porous material, wherein the cross-linking agent is one elected from ethylene glycol dimethacrylate, divinyl benzene, triallyl isocyanurate, pentaerythritol triacrylate and trimethylolpropane triacrylate, and the epoxy group-containing alkene monomer is one selected from glycidyl methacrylate, glycidyl acrylate and glycidyl stearate. According to the invention, the prepared magnetic super-hydrophobic polystyrene-based porous material has super-hydrophobic and magnetic response, can be used for oil-water separation in food industry, chemical industry and petroleum industry, andcan perform automatic oil-water separation under magnetic driving.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a magnetic superhydrophobic polystyrene-based porous material and a preparation method thereof. Background technique [0002] In today's world, mining, textile, food, petrochemical, metal / steel and other industries produce a large amount of oily wastewater, which has become the main pollutant in the world and has a serious impact on people's daily life and the ecological environment. However, oil removal from oily wastewater remains a challenge. Methods such as gravity separation, centrifugation, ultrasonic separation, air flotation, electric field, adsorption and biological treatment are widely used in the treatment of oily wastewater. Among these methods, the application of adsorption is considered to be one of the most promising technologies due to its convenience, low cost, high efficiency, and no secondary pollution. [0003] Therefore, researchers have develop...
