NOVELTY - Toughened polystyrene material comprises 10-20 pts. wt. polystyrene foam particles, 200-300 pts. wt. cement, 100-150 pts. wt. water, 15-20 pts. wt. fly ash, 10-20 pts. wt. kaolin, 2-4 pts. wt. surfactant, 3-8 pts. wt. hydrophobic agent, 5-10 pts. wt. carbon dioxide and 3-8 pts. wt. organically modified graphene oxide. USE - As toughened polystyrene material. ADVANTAGE - The toughened polystyrene material has excellent performance, and improves thermal stability of the polystyrene material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the toughened polystyrene material, which involves adding polystyrene foam particles, cement, fly ash and kaolin to water, stirring and uniformly mixing, adding hydrophobic agent, surfactant and organic modified graphene oxide, stirring and uniformly mixing to obtain a mixture, pouring the mixture to a closed mold, evacuating the air in the mold, introducing carbon dioxide, after 30 minutes, molding by a hydraulic press, and demolding to obtain the toughened polystyrene material.
