NOVELTY - Multi-purpose mattress comprises a graphene composite molded body having a three-dimensional structure formed to have elasticity, where graphene composite molded body includes graphene and a polymer resin. USE - Multi-purpose mattress for Staphylococcus aureus or Streptococcus pneumoniae (klebsiella pneumoniae) after 18 hours, where bacteriostatic reduction rate is 80% or more (claimed). ADVANTAGE - The multi-purpose mattress have excellent mechanical properties, excellent antibacterial, antibacterial, deodorizing rate for harmful gas, antistatic, far-infrared emission, tensile strength and elongation, and very excellent efficacy. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for manufacturing a graphene composite molded article, which involves mixing graphene and a polymer resin, extruding the mixture, and filtering the foreign substances contained in the extruded mixture by discharging to the outside; and (2) a method for manufacturing a multi-purpose mattress, which involves extruding the graphene composite molded body using an extrusion head, transforming the extruded graphene composite molded body into a spring shape, and cutting the deformed graphene composite compact.
