▎ 摘　　要

NOVELTY - Preparing graphene polystyrene foaming material comprises e.g. preparing mass fraction of graphene is 0.1-1% graphene dispersion of styrene, stirring, grinding the dispersion, adding water, dispersant, and stirring, adding low-temperature initiator, raising the temperature is to 40-75 degrees C, adding high temperature initiator, up to 80-95 degrees C, refilling dispersant, constant temperature reaction for 4-9 hours, adding the foaming agent, lifting the temperature to 100-140 degrees C, keeping the temperature for 1-7 hours, taking out the obtained material, filtering and drying. USE - The method is useful for preparing graphene polystyrene foaming material (claimed). DETAILED DESCRIPTION - Preparing graphene polystyrene foaming material comprises (a) preparing mass fraction of graphene is 0.1-1 % graphene dispersion of styrene, (b) stirring, grinding the dispersion, (c) adding water, dispersant, and stirring, (d) adding low-temperature initiator, raising the temperature is to 40-75 degrees C, adding high temperature initiator, up to 80-95 degrees C, refilling dispersant, constant temperature reaction for 4-9 hours, adding the foaming agent, lifting the temperature to 100-140 degrees C, keeping the temperature for 1-7 hours, (e) taking out the obtained material, filtering and drying to obtain the graphene polystyrene foaming material. An INDEPENDENT CLAIM is also included for graphene polystyrene foaming material.
