Embodiment 1

[0018] Embodiment 1: the preparation of antibacterial fabric

[0019] 1. (a) Preparation of nano-zinc oxide: the concentration of zinc sulfate is 1.0mol L -1 , the concentration of ammonium bicarbonate is 2.0mol L -1 , Stir the reaction at 80°C for 2h.

[0020] (b)TiO 2 Preparation of sol: butyl titanate: ethanol: water: glacial acetic acid = 1:9:3:10.

[0021] 2. Using titanate coupling agent to modify the surface of silver-based antibacterial agent, nano-zinc oxide and high-adsorption material respectively, the mass dosage of titanate is 3%.

[0022] 3. Add the modified antibacterial materials with different antibacterial mechanisms to TiO 2 In the sol, the combined antibacterial material sol is obtained, and the molar ratio of the components of the combined antibacterial material is: Ti: Ag: Zn: high-adsorption nanomaterials = 1: 0.01: 0.01: 0.01, and then the sol is evenly applied to the fabric. After drying an antibacterial product is obtained.

Embodiment 2

[0024] Embodiment 2: the preparation of antibacterial plastic

[0025] The method is the same as in Example 1, the difference is that instead of directly applying the obtained combined nano-antibacterial material sol to the substrate, the sol is gelled, vacuum-dried, and the nano-powder obtained after ball milling is evenly added to the plastic , the mass content of nanometer powder is 2%.

[0026] The antibacterial test results are shown in Table 1.

Embodiment 3

[0027] Embodiment 3: the preparation of antibacterial latex product

[0028] The method is the same as in Example 2, the difference is that the composite antibacterial material nano-powder is added to the latex product, and the mass content of the nano-powder is 2%.

[0029] The antibacterial test results are shown in Table 1.

Abstract

A combined nano antiseptic material and its preparation method and products are disclosed. The advantages of the invention lie in 1.combining different antiseptic material and preparing combined nano antiseptic material, taking advantage of synergism and coupling effect of between nano particle, promoting the antiseptic ability 2.The combined antiseptic material has wide spectrum antiseptic function and killing effect to staphylococcus aureus etc. 3.The method can be used in producing sorts of bacteria and virus killing antiseptic material ,such as antiseptic fabric, latex etc.

Description

(1) Technical field: [0001] The invention belongs to the field of chemical industry, in particular to a composite nano antibacterial material and its preparation method and product. (two) background technology: [0002] Nano antibacterial agent is a new type of antibacterial material based on nanotechnology newly developed in recent years. Because of its quantum effect, small size effect and large specific surface area, it has excellent properties that traditional inorganic antibacterial agents cannot match. Antibacterial effect, with the advantages of persistence, heat resistance and resistance to drug resistance. Researchers have used nano-antibacterial technology to develop antibacterial products such as new protective masks, new isolation protective clothing, and medical protective equipment. At present, most antibacterial agents use a single antibacterial mechanism (such as nano-metal or metal ion antibacterial, biological antibacterial, inorganic nano-adsorption antib...
