Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a preparation method of polystyrene plastic with ultrahigh toughness. Background technique [0002] Polystyrene is obtained by bulk polymerization of monomer styrene and is the third largest plastic variety in the world. Polystyrene is colorless, tasteless, odorless, smooth surface, high transparency, low water absorption, strong water resistance, low thermal conductivity and heat capacity. Polystyrene is one of the most widely used polymeric resins. Because of the above advantages, polystyrene films, sheets, and foamed plastics are widely used. Due to the hard and brittle texture of general-purpose polystyrene, low mechanical strength and poor toughness, its application range is limited. Contents of the invention [0003] The object of the present invention is to provide a method for preparing polystyrene plastic with super high toughness in view of the exi...
