Problems solved by technology

[0002] Biodegradable plastics are the main development objects in the fields of packaging bags and garbage bags. The existing degradable plastic bags still have the problem of long degradation time and incomplete degradation. PBAT is a thermoplastic biodegradable plastic, which is butylene adipate The copolymer with butylene terephthalate has the characteristics of both PBA and PBT, and has good ductility and elongation at break, as well as good heat resistance and impact performance; in addition, it also has excellent biodegradability

Abstract

The invention relates to a full-biodegradable garbage bag material. The full-biodegradable garbage bag material is prepared from components in parts by weight as follows: 60-79 parts of PBAT (polybutylene adipate terephthalate), 10-15 parts of modified starch, 1-5 parts of a photosensitizer, 2-4 parts of a compatilizer, 10-15 parts of an anti-fake component and 2-5 parts of a surface treatment component. A common film needs 2-300 years or even longer time for degradation, while the full-biodegradable garbage bag material only needs several months.

Description

technical field [0001] The invention relates to a degradable garbage bag, in particular to a fully biodegradable garbage bag material. Background technique [0002] Biodegradable plastics are the main development objects in the fields of packaging bags and garbage bags. The existing degradable plastic bags still have the problem of long degradation time and incomplete degradation. PBAT is a thermoplastic biodegradable plastic, which is butylene adipate The copolymer with butylene terephthalate has the characteristics of both PBA and PBT, and has good ductility and elongation at break, as well as good heat resistance and impact performance; in addition, it also has excellent biodegradability. Contents of the invention [0003] In order to provide a fully biodegradable garbage bag with fast degradation speed and thorough degradation, the present invention adopts the following technical solution in order to achieve the above object: a fully biodegradable garbage bag material...
