Problems solved by technology

Since the main raw materials of plastics are high-molecular polyolefin resins such as PVC, PS, PP, PE, PET, etc., their products are difficult to degrade or have a long degradation cycle. With the demand for low-carbon life, the development of environmentally friendly plastic materials with agricultural product starch as filler With the gradual rise of applications, however, this material has a fast decomposition rate, weak oxidation resistance and impact resistance

Abstract

The invention provides an environment-friendly polyethylene plastic. The polyethylene plastic is prepared from the following components in parts by weight: 80-100 parts of low-density polyethylene, 15-20 parts of starch, 8-10 parts of dicumyl peroxide, 7-10 parts of glycerol, 8-10 parts of maleic anhydride, 5-8 parts of calcium carbonate, 6-8 parts of glycerol, 2-3 parts of a coupling agent, 0.3-0.5 parts of a antioxidant, 0.5-2 parts of a solubilizing agent and 2-3 parts of water. The environment-friendly polyethylene plastic provided by the invention has the advantages of wide raw material source, short degradation time of products, good environmental protection, high tensile strength and elongation at break, good thermal stability and the like. The invention also provides a preparationmethod of the environment-friendly polyethylene plastic; the process route is simple; and industrial production is easy to realize.

Description

Technical field [0001] The invention belongs to the technical field of packaging materials, and particularly relates to an environmentally friendly polyethylene plastic and a preparation method thereof. Background technique [0002] Most plastics have the advantages of light weight, chemical stability, no corrosion, good impact resistance, and good insulation. Therefore, plastics are widely used in stationery products, catering supplies, packaging supplies and other fields. Since the main raw materials of plastics are high-molecular polyolefin resins such as PVC, PS, PP, PE, and PET, their products are difficult to degrade or have a long degradation cycle. With the demand for low-carbon life, the development of environmentally friendly plastic materials using agricultural product starch as a filler With the application gradually emerging, however, this material has a fast decomposition rate, weak oxidation resistance and impact resistance. Summary of the invention [0003] In vie...
