Problems solved by technology

Among the existing antibacterial agent systems, organic antibacterial agents and silver-based antibacterial agents have high antibacterial efficiency and broad-spectrum antibacterial spectrum, but their safety has been questioned more. On the basis of ensuring antibacterial effect, how to minimize The use of organic antibacterial agents and silver-based antibacterial agents with low safety performance has become a trend
In addition, organic antibacterial agents and silver-based antibacterial agents also have the disadvantage of easy discoloration
At the same time, the use of zinc-based antibacterial agents is safer and has better discoloration resistance, but it is an indisputable fact that its antibacterial efficiency and broad-spectrum are lower than those of organic antibacterial agents and silver-based antibacterial agents.

Abstract

The invention relates to a metal ion-enhanced antibacterial polymer and a preparation method thereof. The metal ion-enhanced antibacterial polymer is mainly prepared from, by weight, 0.1-28 parts of ametal ion-enhanced antibacterial composition, 0-30 parts of a functional assistant, 0-5 parts of a dispersant and 100 parts of a polymer material; and the metal ion-enhanced antibacterial compositionis composed of 100 parts of at least one metal inorganic compound, 0.1-50000 parts of an antibacterial and mildew-proof agent and 0-4000 parts of a carrier. The metal ion-enhanced antibacterial composition is introduced into the antibacterial polymer of metal ion-enhanced antibacterial polymer, and metal ions are combined with an antibacterial and mildew-proof agent, so the amount of the antibacterial agent added to the polymer is reduced, the antibacterial polymer has a broad antibacterial effect, is safe, and achieves good balance between fast sterilization and long-lasting slow release, and the raw material cost of the antibacterial polymer is reduced.

Description

technical field [0001] The invention relates to the field of antibacterial agents, in particular to a metal ion-enhanced antibacterial polymer and a preparation method thereof. Background technique [0002] With the improvement of human living standards, the application of polymer materials with antibacterial function is becoming more and more extensive. In general, polymers with antibacterial function can be obtained by adding antibacterial agents to polymers. Among the existing antibacterial agent systems, organic antibacterial agents and silver-based antibacterial agents have high antibacterial efficiency and broad-spectrum antibacterial spectrum, but their safety has been questioned more. On the basis of ensuring antibacterial effect, how to minimize The use of organic antibacterial agents and silver-based antibacterial agents with low safety performance has become a trend. In addition, organic antibacterial agents and silver-based antibacterial agents also have the di...
