Abstract
The present invention provides a resin composition for flooring characterized in that it comprises a PLA resin, a plasticizer, and an acrylate oligomer. Also, the present invention provides a method for manufacturing flooring, comprising the step of processing flooring which includes a sheet-like molded body of the resin composition and manufacturing the sheet-like molded body by processing the resin composition through extrusion or calendaring methods.
Claims13
A resin composition for flooring materials, comprising:
- a PLA resin;
- a non-phthalate plasticizer;
- and an acrylate oligomer containing a metallic ion,
- wherein the metallic ion comprises at least one selected from the group consisting of zinc, lithium, aluminum, and potassium ion,
- wherein the metallic ion-containing acrylate oligomer has a weight average molecular weight ranging from 5,000 to 10,000,
- wherein the acrylate oligomer is present in an amount of 10 parts by weight to 80 parts by weight based on 100 parts by weight of the PLA resin, and
- wherein the metallic ion is present in an amount ranging from 0.6 to 1.0 part by weight based on 100 parts by weight of the acrylate oligomer.
