PURPOSE: A resin composition for flooring materials is provided to ensure excellent melting efficiency, melting strength, viscosity, shock resistance, heat resistance, mechanical strength and processability even if polylactic acids obtained from raw materials extracted from recycling plant resources are used. CONSTITUTION: A resin composition for flooring materials comprises 100 parts by weight of polylactic acid, 5-60 parts by weight of plasticizer, 0.001-30 parts by weight of lubricant, and 1-60 parts by weight of a processing aid including a copolymer containing methyl methacrylate as a polymerization unit. The polylactic acid is a polymer including, as a polymerization unit, one or more selected from the group consisting of L-lactic acid, D-lactic acid, L,D-lactic acid, L-lactide D-lactide and L,D-lactide. |
