Abstract

The invention belongs to the technical field of bio-based degradation, and particularly relates to a bio-based fully-degradable insect-resistant mulch which comprises a surface layer, a middle layer and an inner layer. The surface layer comprises a surface-layer resin layer and a surface-layer additive layer positioned below the surface-layer resin layer which is modified polyvinyl alcohol resin,and the surface-layer additive layer is an oxidative photodegradation additive; the middle layer comprises a middle-layer resin layer and the middle-layer additive layer positioned below the middle-layer resin layer which is modified polylactic acid resin, and the middle-layer additive layer is an oxidative thermal degradation additive; the inner layer comprises an inner-layer resin layer and an inner-layer additive layer positioned below the inner-layer resin layer which is modified polyhydroxyalkanoate resin, and the inner-layer additive layer is an oxidative biodegradation additive.

Description

technical field [0001] The invention belongs to the technical field of bio-based degradation, and in particular relates to a bio-based fully degradable insect-proof mulch 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 film exists in the so...
