Description

technical field

[0001] The invention relates to a biodegradable material and a preparation method thereof. Background technique

[0002] Traditional films mainly use polyethylene as raw material, but polyethylene is a non-degradable material, which cannot be biodegraded after use and discarded, which will cause white pollution. In today's increasingly serious environmental problems, non-degradable materials are not the future development trend. Environmentally friendly biodegradable materials will be the first choice to solve white pollution and the key materials for future development.

[0003] Polybutylene adipate-terephthalate (PBAT) is a biodegradable material whose final decomposition products are water and carbon dioxide. In addition, PBAT also has excellent tear resistance and impact performance, and is the material of choice for the production of high-performance film materials. The film produced with PBAT as raw material not only has excellent mechanical properti...
