The disclosure provides a low-density PVC plastics flooring and a preparation method thereof, which belongs to the technical field of films for floor. The disclosure provides a low-density PVC plastics flooring, which is prepared from components including, in parts by mass, 100 parts of PVC, 300-380 parts of calcium carbonate, 7-12 parts of a stabilizer, 2-8 parts of processing aid ACR, 12-16 parts of a foaming regulator, 0.1-0.5 parts of a foaming agent, 2-4 parts of G60 lubricant, and 2-4 parts of PE wax. In the disclosure, the density of the PVC plastics flooring is reduced to 1.4-1.6 g/cm.sup.3 even increasing the amount of calcium carbon, thereby greatly reducing the production cost and improving the economic efficiency.
