Abstract

The invention discloses an attapulgite clay / polyanion / polystyrene composite particle and a preparation method thereof. Polystyrene microspheres are used as a carrier, the polyanion modified by the attapulgite clay covers the surface of the polystyrene microsphere to obtain a core-shell structure of the polyanion-polystyrene microsphere, and then the composite particle integrating the conductivity and the heavy metal ion adsorbability is prepared. The prepared composite particle is high in heavy metal ion adsorbability, the application effect of the polystyrene microspheres in the field of water purification can be enhanced, and the water purification effect is remarkable; and meanwhile, the surface of the composite particle has conductivity, so that the problems of fire potential danger caused by the static electricity during the transportation and pre-processing process of the ordinary polystyrene microspheres can be solved, and the attapulgite clay / polyanion / polystyrene composite particle is safer when used as a building insulated material and a packing material.

Description

technical field

[0001] The invention belongs to the technical field of polymers, and in particular relates to attapulgite / polyaniline / polystyrene composite particles and a preparation method thereof. Background technique

[0002] At present, polystyrene microspheres are produced by domestic and foreign manufacturers, which can be used as building insulation materials, packaging materials and water purification and filtration materials, and are widely used. However, it is easy to generate static electricity during transportation and preprocessing, and excessive accumulation can easily cause fire, making it a potential safety hazard in use. Although many improvements have been made to polystyrene microspheres, most of them are to improve their flame retardant performance, which is not a cure for the symptoms.

[0003] Heavy metal adsorption materials are a new class of rapidly developing materials. It can highly selectively adsorb heavy metal ions. It is mainly divided into...
