Oxidized biodegradable vest bag

Abstract

The invention belongs to the technical field of bio-based degradation, and particularly relates to an oxidized biodegradable vest bag. The vest bag 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, wherein the surface-layer resin layer is modified polylactic acid (SHQ-MLA) resin, and the surface-layer additive layer is an oxidation bio-based controllable degradation (YSZJ) additive; the middle layer comprises a middle-layer resin layer and a middle-layer additive layer, wherein the middle-layer additive layer is located under the middle-layer resin layer, the middle-layer resin layer is modified poly(butylene succinate) (SHQ-MBS) resin, and the middle-layer additive layer is a water-retention controllable degradation (BSZJ) additive; and the inner layer comprises an inner-resin layer and an inner-layer additive layer, wherein the inner-layer additive layer is positioned under the inner-layer resin layer, the inner-layer resin layer is modified bio-based polyester bonding (SHQ-GTIE) resin, and the inner-layer additive layer is an oxygen-containing polyolefin controllable degradation (HYZJ) additive.

Description

technical field

[0001] The invention belongs to the technical field of bio-based degradation, in particular to an oxo-biodegradable vest bag. 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 soil, which hinders the development o...
