Embodiment 1

[0044] Take 5g anatase nano TiO 2 , Nano TiO 2 The average particle size is 50nm. Nano TiO 2 Transfer to a beaker and add 200ml of distilled water to make a 50g / L suspension. First make the suspension stir and grind in a high-shear mixing emulsifier at 2500rpm for 45min, then heat the suspension and keep it at 80°C, add 20g of 3-(trimethoxysilyl)propyldodecyldimethyl chloride Ammonium, continue stirring and grinding at 3500 rpm for 3 hours. Then filtered, washed, dried at 100℃ for 4h, and crushed to obtain 1 # Anti-migration high-efficiency compound antibacterial agent.

Embodiment 2

[0046] Take 15g of rutile nano-TiO 2 , Nano TiO 2 The average particle size is 50nm. Nano TiO 2 Transfer to a beaker and add 200ml of distilled water to make a 50g / L suspension. First make the suspension stir and grind in a high-shear mixing emulsifier at 2500rpm for 45min, then heat the suspension and keep it at 80°C, add 20g of 3-(trimethoxysilyl)propyldodecyldimethyl chloride Ammonium, continue stirring and grinding at 3500 rpm for 3 hours. Then filter, wash, dry at 100℃ for 4h, and get 2 # Anti-migration high-efficiency compound antibacterial agent.

Embodiment 3

[0048] Take 5g Fe 3+ Doped nano TiO 2 , Where Fe 3+ Doping amount is 1.5% (mole fraction), doped with nano-TiO 2 The average particle size is 50nm. Will Fe 3+ Doped nano TiO 2 Transfer to a beaker and add 200ml of distilled water to make a 50g / L suspension. First make the suspension stir and grind in a high-shear mixing emulsifier at 2500rpm for 45min, then heat the suspension and keep it at 80°C, add 20g of 3-(trimethoxysilyl)propyldodecyldimethyl chloride Ammonium, continue stirring and grinding at 3500 rpm for 3 hours. Then filter, wash, dry at 100℃ for 4h, and get 3 # Anti-migration high-efficiency compound antibacterial agent.

Abstract

The invention discloses a composite antiseptic and a preparation method thereof. The antiseptic is composed of following raw materials in percentage by weight: 5 to 95% of photo-catalyzed inorganic antiseptic and 5 to 95% of reactive organic antiseptic. The preparation method comprises following steps: wetting photo-catalyzed inorganic antiseptic with the weight percentage mentioned above in distilled water to disperse to form a suspension fluid; stirring and grinding the suspension fluid for 0.5 to 1 hour, adding reactive organic antiseptic according to the weight percentage mentioned above, then stirring and grinding the mixture for another 2 to 3 hours at the constant temperature of 75 to 85 DEG C; filtering, washing, and then drying for 3.5 to 4.5 hours at the temperature of 95 to 105 DEG C, pulverizing the solid to obtain the composite antiseptic. The composite antiseptic has the advantages of excellent antiseptic performance, long effective time, and adaptability for various light intensities.

Description

Technical field [0001] The invention belongs to the technical field of antibacterial materials, and specifically relates to a composite antibacterial agent and a preparation method thereof. Background technique [0002] Due to the deterioration of the environment, the warming of the earth and the pollution of the atmosphere, various infectious diseases have increased, and human understanding of microorganisms (bacteria and viruses) has reached an unprecedented height. Most of the household appliances, tableware, water supply pipes, toys, building materials, OA equipment, communication equipment, and public transportation equipment that are closely connected with people's daily life are plastic products, which are likely to become the medium for the spread of harmful microorganisms in the crowd. Therefore, the development of antibacterial plastics has become a very urgent issue. [0003] Antibacterial material plastic can kill or inhibit the growth and reproduction of microorganism...
