Abstract: Disclosed is a biodegradable resin composition containing an eco-friendly plasticizer, and a biodegradable resin product using same. The biodegradable resin composition according to the present invention contains a biodegradable resin and a plasticizer, and the plasticizer contains a benzoate-based plasticizer. The biodegradable resin composition according to the present invention is eco-friendly since a phthalate-based plasticizer is not used. Also, the present invention has excellent formability and workability at high temperatures by overcoming the disadvantage of the low plasticization rate of a citrate-based plasticizer.

Abstract: The present invention provides a biodegradable resin composition which is modified through a thermally initiated cross linking reaction and comprising a PLA resin, a thermal initiator, and a cross linked monomer. Also, the present invention provides an eco-friendly biodegradable sheet manufactured by extruding the biodegradable resin composition or by processing the biodegradable resin composition using a calendaring method.

Abstract: A custom mosaic flooring enabling customized construction of a flooring is disclosed. More specifically, according to the present invention, a sheet-type flooring printed with specific desired patterns or actual photograph printing images is constructed at a desired position in a partial mosaic form. According to the present invention, the custom mosaic flooring is constructed by printing various patterns including mosaic patterns, carpet patterns, pictures, and graphic patterns using a variety of printing methods including gravure printing, offset printing, transfer printing, dye diffusion thermal transfer printing, silkscreen printing, and actual photograph printing using a printer, thereby fabricating a sheet-type flooring, and fitting thus-fabricated flooring into a desired position. Therefore, construction of the flooring can be conveniently achieved.

Abstract: Disclosed herein is a method for producing a PVC-rubber flooring by a casting process utilizing the sol-gel principle using a rubber sol, which is prepared by milling a liquid or solid rubber in a plasticizer. The rubber sol can be mixed and reacted with a conventional PVC sol. Further disclosed is a PVC-rubber flooring produced by the method. The PVC-rubber flooring has physical properties superior to those of conventional rubber floorings while maintaining the inherent characteristics of the rubber.
