Abstract

The invention discloses an environment-friendly PE plastic particle and a preparation method thereof, and the environment-friendly PE plastic particle comprises the following raw materials by weight: 50-80 parts of polyethylene, 20-30 parts of modified starch, 3-8 parts of calcium stearate, 1-3 parts of a lubricant, 1-3 parts of a plasticizer, 2-4 parts of a dispersant, 2-4 parts of an antifoaming agent, 20-25 parts of ethyl acetate, 1-3 parts of an antioxidant, and 3-5 parts of a degradation agent. The PE plastic particle is prepared by mixing, banburying, extruding and the like. The modified starch is added on the basis of polyethylene, so that the prepared polyethylene plastic particles can be metabolized and utilized by microorganisms in the surrounding environment, and meanwhile, the photodegradation agent is added, so that the photodegradation agent can react under the irradiation of sunlight, polyolefin macromolecules are broken, and thus the PE plastic is easier to degrade, and the problem that the PE plastic is difficult to degrade by microorganisms or natural environment in a natural state and causes great harm to the environment is effectively solved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly PE plastics, in particular to an environment-friendly PE plastic particle and a preparation method thereof. Background technique [0002] PE is polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene resin is a non-toxic, odorless white powder or granule, milky white in appearance, waxy in hand, and low in water absorption, less than 0.01%. Polyethylene film is transparent and decreases with increasing crystallinity. Polyethylene film has low water permeability but high air permeability, so it is not suitable for fresh-keeping packaging but suitable for moisture-proof packaging. Flammable, the oxygen index is 17.4, low smoke when burning, a small amount of molten dripping, the flame is yellow at the top and blue at the bottom, and has the smell of paraffin. Polyethylene has better water resistance. The surface of the product has no polarit...
