Abstract

The invention discloses an environmentally-friendly plastic material, which comprises the following raw materials by weight: 30-40 parts of degradable plastic masterbatch, 15-30 parts of modified starch, 8-12 parts of copolymerized 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 an antioxidant. According to the present invention, the plastic packaging material prepared by using the degradable plastic masterbatch as the raw material has degradability, maintains the impact resistance, the oxidation resistance and the corrosion resistance of the existing packaging material, and can be consumed by the environment by composting the used plastic packaging material of the present invention so as to greatly alleviate the pollution to the environment; and the packaging material has characteristics of wide use range and broad application prospects.

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 ...
