Problems solved by technology

[0006] However, in the prior art, a large amount of elastomer needs to be added for toughening, and the production cost is high due to its high price.
In addition, the selection of parameters such as the particle size of the calcium carbonate filler will also have a great impact on the performance of the modified material.

Abstract

The invention discloses a toughened regenerated modified material manufactured through polyolefin materials of a waste medical plastic transfusion container and a manufacturing method and purpose of the toughened regenerated modified material. The toughened regenerated modified material is good in tenacity, easy to process, low in cost and suitable for manufacturing cold-resistant and shock-resisting materials.

Description

technical field [0001] The invention belongs to the field of waste resources reuse, in particular to the field of resource reuse of medical waste plastics. Specifically, the invention relates to toughened, regenerated and modified pellets prepared from polypropylene materials from waste medical plastic infusion containers. The invention also relates to its preparation method and use. Background technique [0002] At present, a large number of disposable plastic products are used in medical infusion container products, and the number of disposable plastic infusion containers (including disposable plastic bottles and plastic soft bags) and disposable plastic syringes is very large. However, while its use brings convenience, it also produces a large amount of waste, and the production of these plastic products requires a large consumption of petroleum resources. If these discarded medical plastic infusion containers are only landfilled and incinerated, it will not only waste r...
