Problems solved by technology

[0003] However, the existing haloamine antibacterial agents still have the following problems in practical application: the price of synthetic raw materials is relatively expensive; the reaction conditions are harsh (such as high temperature and long reaction time), the production process is complicated, and the cost is high; the yield is low; Synthetic products have poor water solubility, and a large amount of co-solvents must be added to help dissolve them, which increases the cost of finishing and wastewater treatment, and these flammable organic co-solvents also have potential safety hazards; some chloramine antibacterial agents are based on N-hydroxymethyl As an active group, there is still the problem of formaldehyde release during use

Abstract

The invention provides a halide amine antibacterial agent based on cyanuric acid and a synthesis method and an application thereof. The antibacterial agent is a compound of the structure of formula (I) or formula (II). The synthesis method comprises the steps of taking chlorohydrins or cyanuric acid (or derivative thereof) as raw material, reacting for 8-10 hours at 10-40DEG C, removing purities through filtration, obtaining a precursor of halide amine antibacterial agent of the structure of formula (III) or formula (IV), and finally obtaining the product of halide amine antibacterial agent through halogenation reaction. The application of the halide amine antibacterial agent in the preparation of antibacterial material is as follows: working solution prepared by the precursor of the halide amine antibacterial agent and cross-linking agent is used for trimming the material to be treated, then the material is taken out for drying and treating for 3-30 minutes at a high temperature of 100-180DEG C, and the antibacterial material is processed after halogenation. The reaction condition is mild, the technology is simple, the material is cheap and easy to obtain, the halide amine antibacterial agent synthesized by the method and the precursor thereof have a good water solubility and high yield, is environment friendly, and can be used for manufacturing antibacterial material with an excellent antibacterial performance.

Description

technical field [0001] The invention belongs to the technical field of synthesis and antibacterial of haloamine compounds, and in particular relates to a cyanuric acid-based haloamine heterocyclic antibacterial agent, a synthesis method thereof, and an application of the antibacterial agent in preparing antibacterial materials. Background technique [0002] There are a large number of pathogenic and mold-causing harmful microorganisms in the human living environment. They can spread through various materials and product surfaces such as fibers, plastics, rubber, and paper, threatening human health. The use of long-lasting antibacterial materials is the simplest, safest and most effective way to effectively prevent the growth, reproduction, spread and spread of harmful microorganisms, and the core of antibacterial materials is the antibacterial agent loaded on them. Common antibacterial agents currently on the market include heavy metals, benzene chlorides, quaternary ammoniu...
