摘要

An environment-friendly polyurethane blend material is provided to prepare an environment-friendly product due to a biodegradable polylatic acid and to control the property due to the content control of a polylatic acid. A polyurethane blend material comprises polyurethanes 70~90 parts by weight and polylatic acids 10~30 parts by weight. The polyurethane is synthesized from a reactant containing isocyanate and polyol. The polyol is obtained from beans. The polyurethane blend material further includes the recycle waste polyurethane powder.
