Title:
COFFEE GROUNDS MODIFIED BIODEGRADABLE COMPOSITE MATERIAL, AND PREPARATION METHOD AND APPLICATION THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/017030
Kind Code:
A1
Abstract:
A preparation method and an application for a coffee grounds modified biodegradable composite material and a coffee grounds modified biodegradable composite material, made by mixing the following raw materials in proportion, the proportion being the weight ratio: 5-30% polylactic acid 5-30%, 20-70% biodegradable copolyester, 5-20% compatibilising agent, 5-15% plasticising agent, 5-15% tackifying agent, and 10-50% nano coffee grounds. Using the nano coffee grounds together with the synergistic effects of the polylactic acid, the biodegradable copolyester, the compatibilising agent, the plasticising agent, and the tackifying agent, the biodegradable plastic can be modified and product costs reduced, facilitating the full degradation of plastic products after use, and also reusing coffee grounds to reduce product costs.
