Abstract

The invention provides a preparation method of a coated antibacterial nano-material. The preparation method of the coated antibacterial nano-material is implemented by the following steps: 6-18 partsby weight of nanometer cerium are dispersed into 200 parts by weight of polyethylene glycol, 1-2 parts of 5-allyl tetrahydrofuran-2-ol, 0.001-0.01 parts of copper(II) methacryloxyethylacetoacetate, 0.1-0.5 parts of calcium peroxide, 0.1-0.5 parts of sodium dodecyl benzene sulfonate and the like are added, heating is performed, a reaction is performed for 5-12 hours at 65-85 DEG C, and the coated antibacterial nano-material is obtained.

Description

technical field [0001] The invention relates to a preparation method of a bacteriostatic agent, in particular to a coated nano-antibacterial agent with strong antibacterial ability, good resistance to ultraviolet light irradiation, low toxicity and stability. Background technique [0002] With the improvement of people's living standards and awareness of healthy environment, the development of long-acting, low-toxic, broad-spectrum antibacterial materials has attracted more and more attention. Antibacterial home appliances, antibacterial fibers, antibacterial coatings, antibacterial plastics, antibacterial ceramics, and related health care products Came into being. Rare earth elements have unique chemical and physical properties due to their special electronic structures. In the biological field, rare earths have good anti-inflammatory, bactericidal, anti-cancer, anti-coagulant, analgesic and other effects. When different rare earth elements are combined, they will also pro...
