Problems solved by technology

Organic antibacterial agents have poor toxicological safety and poor chemical stability, which will lead to drug resistance of microorganisms; they are easy to migrate and have poor durability, especially poor heat resistance. Many antibacterial plastics are easy to decompose when processed at high temperatures.
Natural antibacterial agents are easy to carbonize and decompose at high temperature, so the application range is narrow and the antibacterial effect is poor

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a polypropylene plastic master batch with magnetic properties. Background technique [0002] At present, plastic products play a very important role in people's daily life and industrial and agricultural production. In order to make plastic products more widely used, people often add antibacterial agents to the plastic masterbatches used to prepare plastic products to obtain antibacterial plastic products. The antibacterial agents used in antibacterial plastics can be classified into inorganic, organic and natural. Organic antibacterial agents have poor toxicological safety and poor chemical stability, which will lead to drug resistance of microorganisms; they are easy to migrate and have poor durability, especially poor heat resistance. Many antibacterial plastics are easy to decompose when processed at high temperatures. Natural antibacterial agents are easy to carb...
