Embodiment 1

[0033] Add 128g of 5,5-dimethylhydantoin, 3840ml of epichlorohydrin and 0.5g of phenyltriethylammonium chloride into a 5000mL round bottom flask, heat at 120°C for 3 hours, then heat at 60-65°C Excess epichlorohydrin was distilled off under reduced pressure, and 1000 ml of 2% NaOH was added after cooling to obtain a hydantoin derivative solution. Take 50g of pure cotton cloth and soak it in the above liquid, let it stand for 45 minutes, and stir the intermediate space for 3 to 5 times. After taking it out, squeeze it until there is no obvious liquid dripping down, first bake it in an oven at 90°C for 45 minutes, and then bake it at 145°C for 30 minutes. Take it out and wash it with tap water, then soak the washed cloth in 0.1% sodium hypochlorite for 45 minutes, rinse it once with tap water, and dry it in the air or at no more than 55°C. Measured by iodometric method, the chlorine content on the cloth is 0.18% (that is, 0.18 g of active chlorine is contained on 100 g of cloth...

Embodiment 2

[0035] Replace the pure cotton cloth in Example 1 with 100% polyester fiber soaked in 2% NaOH solution for 12 hours in advance, and the other processes are the same as in Example 1. The chlorine content is 0.14%.

Embodiment 3

[0037] After the finishing solution prepared by Example 1 was placed for 30 days, the antibacterial cloth was prepared according to the method of Example 1, and the active chlorine content was recorded to be 0.19%.

Abstract

The invention discloses a method for preparing N-halamine antibiotic material, which comprises the following steps: (a) soaking a to-be-treated material in the solution which contains hydantoin derivant or sprinkling / daubing the solution which contains hydantoin derivant on the to-be-treated material to entables the to-be-treated material to adsorb hydantoin derivant, (b) enabling hydantoin derivant to combine on the material by raising temperature, (c) soaking the material after (b) process in the solution which contains active halogen solution or sprinkling / daubing the solution which contains active halogen on the material to make the material activate and be provided with antibiotic activity.

Description

Technical field: [0001] The invention relates to the preparation of amine (N-halamine) antibacterial materials and belongs to the field of new materials. Background technique: [0002] Antibacterial materials, especially antibacterial fiber materials, have a wide range of applications. Bed sheets, quilt covers and medical staff's overalls made of antibacterial fibers in hospitals can reduce the chance of infection and disease transmission, and shoes and socks made of antibacterial cotton fibers can prevent athlete's foot and foot odor. The door handles of public places, computer keyboards, and washers of toilets are made of antibacterial materials, which is conducive to reducing the prevalence of infectious diseases. [0003] Although there are a variety of products claiming to have antibacterial effects on the market, the N-halmine antibacterial materials developed in recent years based on the antibacterial activity of halogen atoms are better than other familiar types (su...
