Abstract

The invention discloses a preparation method of a high-elasticity super-hydrophobic polystyrene-based porous material, which is prepared by in-situ polymerization of styrene, a cross-linking agent A, a cross-linking agent B and an amino compound under the action of an initiator, water and a lipophilic emulsifier. The amino compound is one of 1, 12-diaminododecane, 1, 18-octadecane diamine, polyether amine, polyethyleneimine, aminopropyl terminated polydimethylsiloxane and ethidene diamine, and the amino compound is one of 1, 12-diaminododecane, 1, 18-octadecane diamine, polyether amine, polyethyleneimine, aminopropyl terminated polydimethylsiloxane and ethidene diamine; the cross-linking agent A is one of divinyl benzene, N, N-methylene bisacrylamide, glycidyl methacrylate, glycidyl acrylate and glycidyl ether; and the cross-linking agent B is one of triallyl isocyanurate, pentaerythritol triacrylate, trimethylolpropane triacrylate, ethylene glycol dimethacrylate and dipentaerythritol pentaacrylate. The porous material prepared by the preparation method disclosed by the invention has excellent hydrophobic/oleophylic performance and compression recoverable performance, and oil stain recovery and cyclic utilization of the porous material can be realized in an extrusion mode.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a method for preparing a highly elastic superhydrophobic polystyrene-based porous material. Background technique [0002] With the development of science and technology and the improvement of living standards, the discharge of industrial and domestic sewage is increasing, which poses a huge threat to the ecological environment and human health; Oil spill pollution has become one of the major threats to the marine environment. 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. Compared with immiscible oil / water mixtures, the separation of ...
