PURPOSE: A synthetic resin composition is provided to maintain high tensile strength and impact resistance by using a silicon dioxide impact reinforcing agent while increasing the content of calcium carbonate filler. CONSTITUTION: A polyvinyl chloride resin composition comprises 2-5.0 parts by weight of a stabilizer as an additive, 16-40 parts by weight of a calcium carbonate filler, 0.1-2.0 parts by weight of a titanium dioxide, 0.1-3.0 parts by weight of a processing aid, 0.01-5.0 parts by weight of an impact reinforcing agent, and 0.01-3.0 parts by weight of a lubricant. The impact reinforcing agent is one or more of a CPE-based impact reinforcing agent, a MBS-based thermal impact reinforcing agent, and a silicon dioxide impact reinforcing agent.
