Embodiment 1

[0038] Weigh 27.56g of 70-80% 3-acrylamidopropyltrimethylammonium chloride into a three-necked flask, add 150mL of water, then add 0.12g of sodium persulfate, and pass nitrogen gas for 30min, then heat up to 80°C, and react 8h; after the reaction, the water in the product solution was removed by distillation under reduced pressure, and the obtained solute was purified with ethanol, and the obtained product was dried in a vacuum drying oven at 60°C and 0.2MPa for 12h to obtain the haloamine compound Precursor poly 3-acrylamidopropyltrimethylammonium chloride; dissolve the precursor in a sodium hypochlorite solution with a concentration of 1% by mass, and leave it to react at room temperature for 1 hour. After the reaction is completed, proceed according to the conventional operation method Filtrate and dry to obtain the finished product poly-3-acryloyl chloride propyl trimethyl ammonium chloride of haloamine polymer antibacterial agent.

Embodiment 2

[0040] Weigh 27.56g of 70-80% 3-acrylamidopropyltrimethylammonium chloride into a three-necked flask, add 150mL of water, then add 0.12g of sodium persulfate, and pass through nitrogen for 30min, then heat up to 60°C, and react 12h; After the reaction, the water in the product solution was removed by distillation under reduced pressure, and the obtained solute was purified with ethanol, and the obtained product was dried in a vacuum oven at 60°C and 0.2MPa for 12h to obtain the haloamine compound Precursor poly 3-acrylamidopropyltrimethylammonium chloride; dissolve the precursor in a sodium hypochlorite solution with a concentration of 5% by mass, and leave it to react at room temperature for 1 hour. After the reaction is completed, proceed according to the conventional operation method Filtrate and dry to obtain the finished product 3-acryloyl chloride propyl trimethyl ammonium chloride of the haloamine polymer antibacterial agent.

Abstract

The invention discloses a quaternary ammonium salt group-containing halide amine polymer antibacterial agent, and a preparation method and an application thereof. The compound has a structure represented by the formula (I). The preparation method comprises the steps: with (3-acrylamidopropyl)trimethylammonium chloride as a monomer reaction raw material, sodium persulfate as an initiator and water as a solvent, carrying out a reaction, removing the solvent in the product solution, purifying, drying to obtain a precursor, then carrying out halogenation, filtration and drying to obtain the antibacterial agent finished product. The application in textile antibacterial finishing comprises placing a textile in deionized water for soaking, then placing in an antibacterial agent precursor solution, next soaking in an polymerization anionic solution having the same concentration, washing, drying, and thus completing one time assembly; repeating the above methods, totally assembling for 5-20 times, and halogenating to obtain an antibacterial fabric. The antibacterial agent has excellent antimicrobial performance, has no release of formaldehyde, and is safe and non-toxic; when the antibacterial agent is applied in the textile antibacterial finishing, the prepared antibacterial cotton fabric has good antibacterial property and high antibacterial efficiency.

Description

technical field [0001] The invention belongs to the technical field of synthesis of halide amine antibacterial agents, and in particular relates to a halide amine polymer antibacterial agent containing quaternary ammonium salt groups, a preparation method and its application in textile antibacterial coating finishing. Background technique [0002] There are a large number of pathogenic and mold-causing microorganisms in the human living environment, and textiles such as cotton and hemp can provide nutrients for the growth and reproduction of these harmful microorganisms. Therefore, antibacterial finishing of textile materials makes them have good antibacterial and antibacterial functions appears to be particularly important. [0003] At present, the common fabric antibacterial agents mainly include inorganic antibacterial agents, organic antibacterial agents, natural antibacterial agents and polymer antibacterial agents, etc., but these antibacterial agents have certain shor...
