Abstract

The invention discloses a degradable environment-friendly plastic material which consists of the following raw materials in parts by weight: 30-40 parts of degradable plastic masterbatch, 15-30 parts of modified starch, 8-12 parts of copolymerization 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 part of ethylene glycol terephthalate, 2-4 parts of stearic acid and 0.3-0.5 part of antioxidant. The degradable environment-friendly plastic material disclosed by the invention has the following beneficial effects: a plastic packaging material prepared by taking the degradable plastic masterbatch as a raw material has degradability and maintains the impact resistance, oxidation resistance and corrosion resistance of existing packaging material; the used plastic packaging material can be digested by the environment through composting, thereby greatly relieving environmental pollution; and the packaging material has the advantages of wide application range and broad application prospect.

Description

technical field [0001] The invention relates to a degradable and 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...
