Triazine quaternary ammonium salt halamine antibacterial agent and preparation method thereof, and salt-free antibacterial finishing method

Abstract

The invention provides a triazine quaternary ammonium salt halamine antibacterial agent. The triazine quaternary ammonium salt halamine antibacterial agent is a compound with a structure as shown in a formula (I) in the specification. The preparation method comprises the following steps: (1) dropwise adding an organic solution of 2,2,6,6-tetramethyl-4-piperidylamine into an aqueous or organic solution of cyanuric chloride or cyanuric fluoride, and carrying out a reaction for 1 to 4 h; (2) pouring an aqueous solution of chlorinated N-(2-ethylamino)-pyridine into the reaction solution, carrying out a reaction for 2 to 6 h, dropwise adding an acid-binding agent in the whole process of the reaction, and allowing the pH value of the reaction solution to be 5.0 to 8.0; (3) after the reaction is completed, carrying out filtering, purifying and drying so as to obtain a triazine quaternary ammonium salt halamine antibacterial precursor; and (4) placing the triazine quaternary ammonium salt halamine antibacterial precursor into a halogenated solution, carrying out standing at room temperature for 0.5 to 1.5 h, and after completion of standing, carrying out filtering and drying so as to obtain a quaternary ammonium salt halamine antibacterial agent product. The triazine quaternary ammonium salt halamine antibacterial agent provided by the invention is a salt-free reaction-type halamine antibacterial agent with excellent antibacterial properties and good precursor water-solubility.

Description

technical field [0001] The invention relates to the technical field of antibacterial textiles, in particular to a synthesis method of a triazine quaternary ammonium halide antibacterial agent and a finishing technology in textiles. Background technique [0002] With the rapid development of my country's industry and the remarkable improvement of people's living standards, people's awareness of environmental sanitation and health and safety is increasing day by day. People will inevitably come into contact with various bacteria, fungi and other microorganisms in their life and work. These microorganisms will multiply rapidly and in large numbers under suitable external conditions, and spread diseases through contact and indirect ways, such as in hospitals and hotels. Public places such as bathrooms, nursing homes, etc. will cause cross-infection, and will also affect the wearability of textiles to a certain extent, resulting in bad smell, even fading and deterioration, and re...

Problems solved by technology

People will inevitably come into contact with various bacteria, fungi and other microorganisms in their life and work. These microorganisms will multiply rapidly and in large numbers under suitable external conditions, and spread diseases through contact and indirect ways, such as in hospitals and hotels. Cross-infection in public places such as bathrooms, nursing homes, etc. will also affect the performance of textiles to a certain extent, resulting in bad smell, even fading and deterioration, and reduced mechanical strength.
