Nano-copper antibacterial plastic masterbatch

Abstract

The invention discloses a nano-copperantibacterial plastic masterbatch, which is prepared from the following components in parts by mass: 50 to 65 parts of nanometer-sized neodymium oxide, 8 to 15 parts of polypropylene, 1 to 5 parts of nano-copper powder antibacterial agent, 0.1 to 5 parts of coupling agent, 0.1 to 5 parts of dispersing agent, 2 to 8 parts of polypropylene 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 antioxygen, and 0.5 to 9 parts of dispersing agent. The antibacterial plastic masterbatch disclosed by the invention has the advantages of simple production process, high universality, good processability, capability of continuous large-scale production and the like; a plastic product obtained through plastic processing methods such as injection molding and extruding has a favorable antibacterial effect; the adding of the antibacterial master batch cannot influence the mechanical performance of the plastic product.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a nano-copper antibacterial plastic masterbatch. Background technique [0002] With the development and progress of industry and the improvement of people's material living standards, people have higher and higher requirements for product safety, living and working environment hygiene. Due to the advantages of light weight, no rust, easy molding, good insulation, and no water absorption, plastics have become raw materials for the manufacture of various daily necessities, especially in the fields of kitchen and bathroom products that have been in humid environments for a long time. Since most of the plastic products we come into contact with daily, such as telephones, computers, washing machines, refrigerators, power switches, bus handrails, cutting boards, toilets, etc., do not have antibacterial functions, bacteria can easily adhere to the surface of plasti...

Problems solved by technology

[0004] At present, the commonly used inorganic antibacterial agents on the market are silver-based and zinc-based antibacterial agents. Although silver-based antibacterial agents have high bactericidal ability, their chemical stability is relatively high due to their high chemical potential of 0.798 volts (25°C). Poor, under ultraviolet radiation or after heating to a certain temperature, silver ions are reduced to metallic silver and immediately converted to silver oxide, making the product gray and black, which not only reduces its commercial value, but also weakens its antibacterial properties

In addition, the price of silver-based antibacterial agents is relatively high, and their antifungal ability is relatively weak

Although the zinc-based antibacterial agent has no discoloration problem and is cheap, its antibacterial performance is low and cannot meet the antibacterial requirements
