Abstract

The invention discloses a modified waste polyethylene having good impact strength. The polyethylene is prepared from, by weight, 25-28 parts of oxidized sodium alginate modified rosin resin, 18-22 parts of an inorganic filling material, 3-6 parts of polydiethylene terephthalate, 0.3-0.6 part of a lubricant, 1.0-1.3 parts of a plasticizer, 1.6-2.2 parts of a coupling agent, and 88-95 parts of wastepolyethylene. The polyethylene has good impact strength and good wear resistance.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a modified waste polyethylene with good impact strength. Background technique [0002] With the rapid development of the plastics industry, polyethylene, as a general-purpose plastic, is widely used in daily necessities, construction, automobile manufacturing and other fields. However, with the expansion of polyethylene application fields and the increase in usage, waste polyethylene is also increasing day by day. Due to the aging and degradation of waste polyethylene, its physical properties are far inferior to that of virgin polyethylene, and its application is also greatly limited, and can only be used to make low-performance products. If it is not applied, it will waste resources and cause great pollution to the environment. The recycling of waste polyethylene is conducive to the sustainable development of the plastics industry. To sum up, the regeneratio...
