The formula of the self-deposit adsorption PVC floor material was studied in this study. With the increasing of the super-fine CaCO3Subscript text powder and substituting of epoxy soybean oil, the properties of the product were improved. The study revealed that when the addition of super-fine CaCO3 powder was 30phr, ESO 10phr, the general properties of the product was good. 1phr ACR was used to improve the processing performance. This study provided improvement method and base data for modification of PVC composited floor material.
