Title:
NANOSCALE PLANT FIBER MODIFIED BIODEGRADABLE COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/017031
Kind Code:
A1
Abstract:
A preparation method for a nanoscale plant fiber modified biodegradable composite material and an application. The preparation method comprises the following steps: (1) grinding a dried plant fiber to obtain a nanoscale plant fiber; (2) adding the nanoscale plant fiber from step (1), polylactic acid, biodegradable copolyester, a compatibilizer, a plasticizer, and a tackifier into a blender in proportion for uniformly mixing to obtain a mixed material; and (3) adding the mixed material that is uniformly mixed into a twin-screw extruder, and performing extrusion granulation to obtain the nanoscale plant fiber modified biodegradable composite material. By using the nanoscale plant fiber and collaborating with the synergetic effect of the biodegradable copolyester, the compatibilizer, the plasticizer, the tackifier, polylactic acid, and the like, a biodegradable plastic is modified and product costs are reduced, so that a plastic product is fully degraded after use, the plant fiber is recycled and product costs are reduced.
