Wear-resistant degradable antistatic packaging material and preparation method thereof

Abstract

The invention discloses a wear-resistant degradable antistatic packaging material. The packaging material comprises the following raw materials by weight: 2-4 parts of a synergist, 45-55 parts of a degradable polymer, 2-4 parts of a coupling agent, 15-25 parts of starch, 0.8-1.4 parts of an antistatic agent, 1-3 parts of graphene, 6-8 parts of a wear-resistant additive, 4-8 parts of lignin, 0.4-0.6 part of sodium humate and 1-2 parts of a plasticizer. The packaging material provided by the invention has good antistatic, wear-resistant and scratch-resistant properties, superior mechanical strength and mechanical properties and good impact resistance and dimensional stability; moreover, the material has good degradation ability after being discarded and poses little pollution to environment; meanwhile, a preparation method for the material has the advantages of lower material cost, easy availability of the raw materials, simple process, high practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a wear-resistant and degradable antistatic packaging material and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people are paying more and more attention to the quality of life. While there are many requirements for product performance, the packaging and appearance of products are also getting higher and higher. When people choose products, product packaging The quality and appearance of the product have also become a very important consideration for people to choose products and judge product quality. [0003] At present, the outer packaging film materials on the market usually use vinyl as the raw material, the most common of which is polyvinyl chloride. [0004] alkene. Polyvinyl chloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride under the action of an in...

AI Technical Summary

Problems solved by technology

Polyvinyl chloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It has good mechanical properties and is widely used in the packaging of cooked food products, but the stability of PVC material is poor. It will decompose under the action of heat and light, and the mechanical strength will also decrease. As food packaging, long-term use will affect human health and cannot meet the requirements of sterility. These limit the scope of application of PVC material films

[0005] On the other hand, most of the raw materials of the plastic industry come from oil. With the gradual reduction or even exhaustion of oil and natural gas resources, the plastic industry will face a shortage of raw materials; "White pollution" destroys the ecological environment
