BIODEGRADABLE RESIN COMPOSITION CONTAINING POLYLACTIC ACID FOR MANUFACTURING CELLULAR PHONE CASE AND MANUFACTURING METHOD OF CELLULAR PHONE CASE USING THE SAME

摘要

The present invention relates to a biodegradable resin composition for a mobile phone case containing polylactic acid and a method for producing a mobile phone case using the same.;The present invention is a biodegradable resin composition containing a reinforcing agent selected from the group consisting of talc, glass fiber and carbon fiber in polylactic acid, wherein the polylactic acid is used in a chain extender and / or in polycaprolactone or polyhydroxyalkanoate. Further containing the selected additional components to improve the tensile strength, flexural strength, impact strength of the biodegradable polylactic acid, to provide a biodegradable resin composition suitable for the mobile phone case, melt kneading the biodegradable resin composition, cooling After that, it is possible to provide a method for producing a biodegradable mobile phone case made by injection. Furthermore, the manufacturing method of the present invention can be applied to the production of PMP or MP3 cases.;Polylactic acid, talc, glass fiber, carbon fiber, mobile phone case
