Environment-friendly plastic material

Abstract

The invention discloses an environment-friendly plastic material. The plastic material comprises the following components in parts by weight: 30-40 parts of degradable plastic master batches, 15-30 parts of modified starch, 8-12 parts of copolymerization type polypropylene, 2-4 parts of glycidyl methacrylate, 3-5 parts of carbon black, 1-3 parts of glass fiber, 1-3 parts of plant fiber, 0.6-0.8 parts of ethylene terephthalate, 2-4 parts of stearic acid and 0.3-0.5 parts of an anti-oxidant. The environment-friendly plastic material has the beneficial effects that the plastic package material which is prepared by degradable plastic master batches as raw materials has degradability, and shock resistance, oxidation resistance and corrosion resistance of the package material in prior art are kept; after usage, the plastic material is composted and degraded in the environment, so that environment pollution is substantially alleviated; the packaging material has a wide usage range and a wide application prospect.

Description

technical field [0001] The invention relates to an environment-friendly plastic material. Background technique [0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Beverage bottles are mostly made of plastic products. The two materials, polyethylene and polypropylene, are non-toxic and tasteless, and are safe for the human body when used to fill beverages. However, once polyethylene is subjected to high temperature or acid corrosion, it will slowly dissolve and release organic solvents, which will cause harm to the human body. There are three types of plastic products widely used in food packaging: polyvinyl chloride, polyethylene, and polystyrene. It is not harmful to human health if it is used to hold cooking oil in a short period of time. But, use them to hold edible oil for a long time, can pollute food, cause the harm to human body. [0003] The element vinyl chloride in polyvinyl ...
