Abstract
The invention is suitable for the technical field of resource recycling, and provides a modified recyclable recycled high-impact-resistant PE (Polyethylene) and a preparation method thereof. The modified recyclable recycled high-impact-resistant PE is characterized in that: PE waste plastic is prepared by adopting multipathobtained by recycling through multiple ways, wherein the total proportion of the recyclable recycled plastic and the stuffing is 90 percent or more, ethylenecopolymer and ionic polymer are added, and rigid inorganic particles are added, so that a material is enhanced, meanwhile, the toughness and abrasion resistance of the material can be improved greatly; the impaction resistance of the prepared modified recyclable recycled particles is increased by 1 to 2 times compared withhigher than the conventional recyclable particles; moreover, the inorganic stuffing can be added, thereby improving the rigidity of the material is improved, meanwhile, the material is taken asthe stuffing, so thatand reducing the cost of the material is lowered; the plastic tray has the advantages of low preparation cost and high plastic tray performance.
Description
technical field [0001] The invention belongs to the technical field of resource regeneration, and in particular relates to a modified recycled high-impact PE used for plastic pallets and a preparation method thereof. Background technique [0002] With the development of my country's plastic industry, a large amount of plastic waste is produced. The amount of waste plastics produced in my country every year is about 14 million tons. They cannot be decomposed naturally and do not rot, which has become an eye-catching social problem. The recycling and utilization of waste plastics can turn industrial waste into extremely valuable industrial production raw materials and realize the recycling of resources, which has potential significance that cannot be ignored. At present, all countries in the world pay attention to and support the recycling and recycling methods of waste plastics. In the solid waste of industrialized countries, waste plastics account for about 4%-10% or 10%-20...
