preparation example Construction

[0018] The invention provides a kind of preparation method of antibacterial agent, comprising the following steps: dissolving cyanuric chloride in acetone, stirring, then dropwise adding the acetone solution of 4-amino-2,2,6,6-tetramethylpiperidine, Adjust the pH value to 7, stir to obtain a mixed solution; heat the mixed solution to 45°C, add dropwise an aqueous solution of N-(2-aminoethyl)pyridinium chloride, react for 1-3 hours, and adjust the pH value to 6. Filter to obtain the antibacterial agent.

[0019] As a preferred solution, the mass ratio of cyanuric chloride to 4-amino-2,2,6,6-tetramethylpiperidine is 90-100:7-8.

[0020] The N-(2-aminoethyl)pyridinium chloride was prepared according to the following method: 2-chloroethylamine hydrochloride, pyridine and water were mixed, stirred and refluxed for 1 hour, extracted with toluene; the aqueous layer was extracted with concentrated hydrochloric acid The pH value was adjusted to 3, then the solvent was evaporated, and ...

Embodiment 1

[0033] Preparation of antibacterial agent:

[0034] Step 1) Synthesis of N-(2-aminoethyl)pyridinium chloride

[0035] In a 25L round bottom flask, 1.16kg of 2-chloroethylamine hydrochloride and 2.77kg of pyridine were mixed, and then 1L of water was added. The mixture was stirred and heated to reflux for 1 hour, then the mixture was cooled to room temperature and extracted three times with 1 L of toluene. Among them, the molar ratio of 2-chloroethylamine hydrochloride:pyridine is 1:3.5. The pH of the aqueous layer was adjusted to 3 with concentrated hydrochloric acid, then the solvent was evaporated and the crude product was obtained using a rotary evaporator under vacuum. After purification with isopropanol, N-(2-aminoethyl)pyridinium chloride was collected by filtration in 92% yield.

[0036] Step 2) Synthesis of triazine-based quaternized N-halamines

[0037] 922.g of cyanuric chloride was dissolved in 1L of acetone and stirred at 10°C for 10 minutes. Then, 78 g of 4-a...

Embodiment 2

[0041] The fabric carpet is dipped into the final solution triazine-based quaternized N-halamine. After 10 minutes of treatment at 70°C, the temperature was raised to 80°C and a small amount of sodium hydroxide was added. The reaction was left for 1 hour, and the fabric was removed, rinsed thoroughly with tap water, and dried at 60°C.

Abstract

The invention provides a preparation method of a household antibacterial carpet and an antibacterial agent, which comprises the following steps: soaking carpet cloth into a triazinyl quaternized N-halamine solution for treating for 5-15 minutes at 50-70 DEG C; and heating to 80-90 DEG C, adding sodium hydroxide for reacting for 1-3 hours, cleaning and drying to obtain the household antibacterial carpet. Compared with the prior art, the invention has the advantage that triazinyl quaternized N-halamine is used as the antibacterial agent, quaternary ammonium salt and N-halamine can adsorb pathogenic microorganism with negative charge, destroy the cell wall structure of the microorganism so that dissoluble matter leaks out, and inhibit pathogen oxidase and dehydrogenase. Because the quaternaryammonium salt and the N-halamine coexist, the prepared antibacterial carpet performs excellent organism-killing activity on staphylococcus aureus and escherichia coli. An experiment result shows thatthe household antibacterial carpet prepared by the invention has good antibacterial effect.

Description

technical field [0001] The invention relates to the field of carpets, in particular to a method for preparing household antibacterial carpets. Background technique [0002] Carpet is a floor covering made of cotton, hemp, wool, silk, grass and other natural fibers or chemical synthetic fiber materials, which are braided, tufted or woven by hand or mechanical technology. One of the popular arts and crafts categories, it covers the ground of residences, hotels, gymnasiums, exhibition halls, vehicles, ships, aircraft, etc., and has the effects of noise reduction, heat insulation and decoration. At first, the carpet was only used for paving the floor, and it played the role of keeping out the cold and damp, and it was good for sitting and lying. , moisture-proof, comfortable, sound insulation and other functions, but also noble, gorgeous, beautiful, pleasing to the eye, thus becoming an essential product for high-end architectural decoration. [0003] However, carpets are easy...
