摘要

PPROBLEM TO BE SOLVED: To provide an automobile interior/exterior material having physical properties suited therefor by using an environmentally compatible bio-composite material composition. PSOLUTION: The bio-composite material composition comprises 65-85 wt.% of a polypropylene resin, 10-30 wt.% of a soybean protein and 2-10 wt.% of zinc sulfate, wherein the polypropylene resin has a melt flow index (MI value) of 0.5-30 g/10 min (ASTM D1238, 230°C) and the soybean protein has an average particle size of 5-50 μm. A sheet comprising the composition, the automobile interior/exterior material comprising the sheet, and a method of manufacturing the sheet are also provided. PCOPYRIGHT: (C)2010,JPO&INPIT
