Abstract

The invention belongs to the technical field of bio-based degradation, in particular to an oxidative biodegradable high temperature resistant gas permeable film, comprising a surface layer, a middle layer and an inner layer. The surface layer comprises a surface resin layer and a surface additive layer. The surface resin layer is a modified polylactic acid (SHQ-MLA) resin. The surface additive layer is an environmental oxidative degradation (YJZJ) additive. The middle layer comprises an intermediate resin layer and a middle additive layer. The middle additive layer is located below the middle resin layer. The intermediate resin layer is a modified bio-based polyolefin bonding (SHQ-MTIE) resin. The middle additive layer is an oxidative compost degradation (DFJ) additive. The inner layer comprises an inner resin layer and an inner additive layer. The inner additive layer is located below the inner resin layer. The inner resin layer is an oxygen-containing resin controlled degradation (YZSZ) resin. The inner additive layer is an oxidative biodegradation (SJZJ) additive.

Description

technical field [0001] The invention belongs to the technical field of bio-based degradation, and in particular relates to an oxidative biodegradable high-temperature-resistant and breathable film. Background technique [0002] With the rapid development of the economy, people's damage to the environment is becoming more and more serious, especially non-degradable plastics, which are not easy to be degraded by soil microorganisms after being randomly thrown away by people, remain in the soil for a long time, causing serious pollution to the ecological environment . Disposable tableware, disposable plastic products and agricultural mulch are difficult to recycle, and the traditional treatment methods are mainly incineration and landfill. Incineration will produce a large amount of harmful gas, which pollutes the environment; burial means that the polymers in it cannot be decomposed by microorganisms in a short time, which also pollutes the environment. The residual plastic ...
