Problems solved by technology

[0003] However, most of the existing mosquito net bags are made of plastic braided ropes, so the time required for the waste degradation process is extremely long, which greatly increases environmental pollution and resource consumption, and increases the burden of self-regulation of the ecological environment. thereby greatly affecting the ecological environment

Abstract

The present invention relates to the technical field of degradable materials, and discloses a degradable mosquito net bag, the mosquito net bag preparation raw materials are degradable materials, and the raw materials comprise a base material, an antioxidant and a reinforcing agent; wherein the base material is prepared from the following raw materials in parts by weight: 10-50 parts of synthetic fiber, 10-50 parts of copolyester and 0-50 parts of starch, and the antioxidant is prepared from the following raw materials in parts by weight: 1-2 parts of an anti-free radical agent and 1-2 parts of a toughening agent. The reinforcing agent is prepared from the following raw materials in parts by weight: 0-3 parts of a lubricating agent, 1-50 parts of filler and 0.04-2.5 parts of polycaprolactone, through a melting and mixing process of copolyester and starch, the weaving limit degradation rate of synthetic production is remarkably improved compared with that of a traditional plastic weaving process, and in the degradation process, the degradation rate of the plastic weaving process is greatly improved. The self-regulation burden of the ecological environment is greatly reduced, so that the environmental protection is obviously improved, and meanwhile, the toughness of the first-class copolyester is greatly improved.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a degradable mosquito net bag. Background technique [0002] Biodegradable plastics refer to a class of plastics that are degraded by the action of naturally occurring microorganisms such as bacteria, molds (fungi) and algae. The ideal biodegradable plastic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and is finally inorganicized to become an integral part of the carbon cycle in nature. "Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable plastics are polymer materials that have the properties of both "paper" and "synthetic plastics", and the degradation of polymers refers to the process of breaking polymerized macromolecular chains caused by chemical and physical factors. The degradation process of m...
