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

Abstract

The invention discloses nano-antibacterial composite plastic masterbatch which is prepared from the following ingredients in parts by weight: 50 to 65 parts of nano-silver, 8 to 15 parts of polyethylene, 1 to 5 parts of polymethyl phenolic aldehyde, 0.1 to 5 parts of coupling agent, 0.1 to 5 parts of dispersing agent, 2 to 8 parts of polyethylene wax, 50 to 65 parts of nanometer titania antibacterial agent, 20 to 40 parts of plastic resin, 20 to 70 parts of carrier resin, 15 to 40 parts of pigment, 15 to 40 parts of filler, 0.5 to 2 parts of antioxidant and 0.5 to 5 parts of dispersing agent. The plastic masterbatch is wide in antibacterial bacterial spectrum, lasting in antibacterial action, good in antibacterial performance, good in thermal stability, good in high temperature resistance, not prone to color change, good in compatibility and dispersibility and free of changing an original plastic processing technology.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a nanometer antibacterial composite plastic masterbatch. 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 t...
