Problems solved by technology

[0003] The traditional agricultural mulch film is difficult to degrade, and the residual mulch film blocks water transmission in the soil and hinders the growth of the root system. It is not good for the growth of crops and produces a large amount of soil environmental pollution. The degradable mulch film can solve these problems well, but the current degradable mulch film The degradation is not complete, so it is necessary to develop a biodegradant that can completely degrade the plastic film for the production of plastic film

Abstract

The invention provides a biodegradation agent. The biodegradation agent comprises 2%-6% of manganese stearate, 0.4%-1.2% of iron stearate, 5%-10% of copper stearate, 0.04%-0.4% of a silane coupling agent, 90%-70% of low-density polyethylene or polypropylene and 0.06%-0.5% of a fertility increasing agent. After the biodegradable additive disclosed by the invention is added, various performance indexes of non-degradable conventional plastic meet requirements during use, and the plastic can be quickly decomposed after the service life is ended, so that a mulching film can be completely degraded, thereby avoiding white pollution; meanwhile, due to the addition of the fertility increasing agent, the mulching film has a certain fertility increasing effect on the land after being degraded.

Description

technical field [0001] The invention mainly relates to the technical field of biodegradation, in particular to a biodegradation agent and a preparation method thereof. Background technique [0002] Mulch film is the ground cover film, usually transparent or black polyethylene film, but also green or silver film, used for ground cover to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms etc., to promote the function of plant growth. [0003] The traditional agricultural mulch film is difficult to degrade, and the residual mulch film blocks water transmission in the soil and hinders the growth of the root system. It is not good for the growth of crops and produces a large amount of soil environmental pollution. The degradable mulch film can solve these problems well, but the current degradable mulch film The degradation is not complete, so it is necessary to develop a biode...
