NOVELTY - Elastic graphene expanded Polystyrene (EPS) comprises 0.05-0.5 wt.% elastomer, 0.1-1 wt.% graphene, 20-50 wt.% styrene, 0.5-1 wt.% calcium hydroxyphosphate, 0.02-0.05 wt.% surfactant, 0.02-0.05 wt.% stabilizer, 0.5-3 wt.% BPO (dibenzoyl peroxide), 1-5 wt.% foaming agent, and 30-75 wt.% deionized water. USE - Elastic graphene expanded Polystyrene. ADVANTAGE - The elastic graphene expanded Polystyrene has certain elastic deformation ability, is inexpensive, and by adding an elastomer and graphene, the EPS is given light weight, high strength and high elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an elastic graphene EPS, which involves: (A) weighing each raw material by weight percentage and reserving it; (B) taking the elastic body and grinding it by ball milling; (C) blending the elastomer treated with graphene; (D) extruding and granulating the mixture to prepare a graphene elastomer master batch; and (E) adding the graphene elastomer masterbatch to styrene, calcium hydroxyphosphate, surfactant, stabilizer, BPO (dibenzoyl peroxide), foaming agent, and deionization in the EPS system of the water combination, and carrying out polymerization reaction to prepare an elastic graphene EPS product.
