▎ 摘 要
NOVELTY - A nanomaterial modified flame retardant toughening regeneration polystyrene composite material comprises regenerated polystyrene particle and nanomaterial comprising attapulgite adsorption graphene. The regenerated polystyrene particle is waste polystyrene foamed material obtained by limonene steam treatment and plasma activation treatment. USE - Nanomaterial modified flame retardant toughening regeneration polystyrene composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nanomaterial modified flame retardant toughening regeneration polystyrene composite material comprising removing waste polystyrene foamed material surface impurity, cutting to size of 0.2-0.5 cm3, transferring into sealed environment, plasma treating to obtain plasma pre-treated waste polystyrene foamed material, placing into steam chamber, introducing limonene steam containing auxiliary agent at room temperature to obtain transparent polystyrene solution, regenerating and modifying with concentrated sulfuric acid to obtain sulfonated polystyrene particles, adding to calcium chloride solution nanomaterial, adding styrene monomer, uniformly stirring, adding initiator, heating to 130-140 degrees C, stirring, taking out, and drying.
