Title:
BIODEGRADABLE MATERIAL, RAW MATERIAL COMPOSITION THEREOF, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/142240
Kind Code:
A1
Abstract:
A biodegradable material. A raw material composition of the biodegradable material comprises the following components in parts by weight: 20-80 parts of polybutylene adipate/terephthalate, 5-30 parts of polylactic acid, 10-50 parts of papermaking waste, 5-40 parts of cellulose and 2-15 parts of an auxiliary. Adding the papermaking waste and cellulose to a biodegradable resin significantly reduces the cost of the biodegradable material. Moreover, the use of the papermaking waste and cellulose is expanded, and the degree of utilization of the papermaking waste is increased, so that waste is turned into wealth.
