Environmental-friendly plastic film and preparation method thereof

Abstract

The invention relates to an environmental-friendly plastic film and a preparation method thereof. The environmental-friendly plastic film comprises the following raw materials: polyethylene, natural mineral substance and binchotan powder, natural plant starch, Pulullan, biodegradable material, vinyl chloride resin, trifluoroacetic acid, inorganic mineral filler, curing agent, plasticizer, composite antibacterial agent, mineral oil, polybutylene hot sol, nanometer coal forming master batch, sodium hydrogen sulfite and hydroxyl polyphosphoester. The environmental-friendly plastic film is added with biological degrading material, and thus the film can be automatically degraded under the effect of enriched oxygen and microorganism; the waste film can be completely degraded and digested by microorganism in the nature cycle; the preparation method of the invention is simple in technique, convenient to operate, low in price of raw material applied, high in production efficiency, easy to practice industrialization and produce by an ordinary plastic film blowing machine. The environmental-friendly plastic film has anti-bacteria and germicidal functions; moreover, its intensity, toughness and heat resistance are excellent.

Description

technical field [0001] The invention relates to the field of plastic film materials, in particular to an environment-friendly plastic film and a preparation method thereof. Background technique [0002] Although traditional plastic products on the market have functional characteristics such as chemical resistance, impact resistance, and moisture resistance, they also have disadvantages such as poor environmental performance and low toughness and strength, which may easily lead to changes in the original functional characteristics of plastic products. , and greatly shorten the service life, increase the production cost and working hours, and increase the cost of the product from the side; heavy metals such as formaldehyde and benzene will be emitted during use, polluting the environment, affecting air quality and endangering people's health. There are many kinds of plastic products, and it is very difficult to classify them. It is not economically cost-effective to reali...

AI Technical Summary

Problems solved by technology

However, the existing degradable products only take into account one aspect of the degradation environment, and the physical and mechanical properties of the product, such as tensile properties and elongation at break, cannot meet the actual physical performance requirements of the final product.

The strength, toughness, and heat resistance of the current environmentally friendly plastics are not ideal and need to be improved. Therefore, it is imperative to study an environmentally friendly plastic product that is not only degradable but also has a variety of excellent properties.
