Abstract

The invention discloses a copper-doped plastic anti-microbial master batch and belongs to the technical field of the anti-microbial master batch. The copper-doped plastic anti-microbial master batch comprises the following components in parts by weight: 80-96 parts of polyethylene glycol terephthalate (PET), 0.3-20 parts of nanometer copper, 0.1-5 parts of nanometer zinc, 0.3-10 parts of nanometer silver and 0.01-3 parts of modifier. The bronze powder which is formed by mixing nanometer copper with the zinc powder has the characteristics of abundant layer, bright color and golden metallic luster; after the bronze powder is mixed with the nanometer silver at a certain ratio, the mixture has a toning function and can be used as a metal pigment with an anti-microbial effect; besides, the nanometer copper, zinc and silver have an anti-microbial characteristic; after the nanometer copper, zinc and silver are mixed, a synergistic effect is promoted and the anti-microbial effect is further enhanced.

Description

technical field [0001] The invention relates to a copper-doped plastic antibacterial masterbatch, which belongs to the technical field of antibacterial masterbatch. Background technique [0002] Antibacterial masterbatch is a concentrate made by uniformly dispersing various antibacterial agents in the matrix resin. After mixing a certain amount of antibacterial masterbatch and corresponding resin particles, according to the processing and molding methods of plastics and fibers, plastic parts, products and antibacterial fibers with antibacterial effects (bactericidal and antibacterial effects) on the surface can be obtained. [0003] Nano-silver, zinc, and copper are all materials with antibacterial properties. Among them, nano-silver has a very strong antibacterial ability, which is 1000 times that of nano-zinc. At present, nano-silver is mainly used to make antibacterial masterbatches in the market. However, nano-silver is white, and the color of antibacterial masterbatch ...
