Abstract

The invention belongs to the technical field of bio-based degradation, and particularly relates to a novel bio-based controllable degradation freezing film 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, wherein the surface layer resin layer is environment-controllable degradation (HJSZ)resin, and the surface layer additive layer is an oxidative photodegradation (GJZJ) additive; the middle layer comprises a middle resin layer and a middle additive layer, wherein the middle additivelayer is located below the middle resin layer, the middle resin layer is modified polycaprolactone (SHQ-MCL) resin, and the middle additive layer is an oxidative thermal degradation (RJZJ) additive; the inner layer comprises an inner layer resin layer and an inner layer additive layer, the inner layer additive layer is located below the inner layer resin layer, the inner layer resin layer is triple controllable degradation (SKSZ) resin, and the inner layer 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 a novel frozen film with controllable bio-based degradation. 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...
