Reaction-type halogen amine antibacterial agent, and synthetic method and application thereof

Abstract

The invention relates to a reaction-type halogen amine antibacterial agent, and a synthetic method and application thereof. The antibacterial agent is a compound with a structure shown in a formula (I). The synthetic method is as follows: dropwise adding a sulfanilic acid solution into a cyanuric chloride or cyanuric fluoride solution, reacting at 0-20 DEG C for 1-4 h, then adding 2,2,6,6-tetramethyl-4-piperidine alcohol solution, reacting at 20-60 DEG C for 2-6 h, filtering, purifying and drying to obtain a precursor of the halogen amine antibacterial agent, and carrying out halogenation to obtain the finished product of the halogen amine antibacterial agent. Application of the halogen amine antibacterial agent to antibacterial finishing of textile is as below: dissolving the precursor of halogen amine antibacterial agent and a metal salt catalyst in the water to prepare a finishing liquid, immersing the textile in the finishing liquid, adding an alkali agent, impregnating at 40-60 DEG C for 2-6 h, taking out the textile, washing and drying the textile, and carrying out halogenation to obtain antibacterial textile. The antibacterial agent provided by the invention has superior antibacterial properties, and the precursor has good water solubility; textile subjected to finishing of gains superior bactericidal functions and high sterilization rate and efficiency; and the method has the advantages of simple process, no toxicity or pollution, and meets the processing requirements of ecological textiles.

Description

technical field [0001] The invention belongs to the field of antibacterial technology, and in particular relates to a synthesis method and application of a reactive haloamine antibacterial agent. Background technique [0002] There are a variety of pathogenic bacteria and molds in nature, which pose a serious threat to human normal life and health. Textiles, especially cotton fibers, are the materials that the human body comes into contact with the most. The sugars in the fibers, as well as the sweat, sebum and other human secretions that stick to them during wearing, will provide the necessary nutrients for the growth and reproduction of these harmful microorganisms, and textiles The porous structure itself is also conducive to the attachment of microorganisms. For the wearer, it is not only easy to cause cross-infection and become an important source of disease transmission, but also affects the performance of textiles to a certain extent, resulting in bad smell. Even fad...
