Embodiment 1

[0037] Embodiment 1 The zirconium phosphate type inorganic antimicrobial agent that the weight 6g silver content is 3.5%, primary particle diameter average value is 35nm, aggregate apparent average particle diameter is 1.6 μ m, moves into the 150ml of the lining polyurethane resin of sand mill Stainless steel body barrel. 100g of zirconia beads of Φ0.5mm are placed in the barrel in advance. After adding 0.003g of sodium thiosulfate, add 100ml of distilled water and grind at 2000rpm for 5min. Add 0.05g of N-aminoethylaminopropyltrimethylsilane, increase the rotational speed to 3000rpm, and grind for 5min. Add 10g of 1,1'-hexamethylenebis[5-(4-chlorophenyl)biguanide] digluconate, and grind at 3000rpm for 5min. The zirconia beads were separated using a 325 mesh sieve. Then, add 0.5g TWEEN-80 to the sieved mixed liquid, and disperse at 4000rpm for 5min. Add 10 g of polyacrylate emulsion HB959 (Beijing Huyi Chemical Factory), and stir at 100 rpm for 10 min to become a milky whi...

Embodiment 2

[0038] Embodiment 2 The silica gel type inorganic antibacterial agent that the weight 6g silver content is 3.0%, zinc content is 8.0%, average particle diameter is 1.2 μ m, maximum particle diameter is less than 5 μ m, moves into the 150ml of the liner polyurethane resin of sand mill Stainless steel body barrel. 100g of zirconia beads of Φ0.5mm are placed in the barrel in advance. After adding 0.003g of sodium thiosulfate, add 100ml of distilled water and grind at 2000rpm for 5min. Add 0.05g of N-aminoethylaminopropyltrimethylsilane, increase the rotational speed to 3000rpm, and grind for 5min. Add 10g of 1,1'-hexamethylenebis[5-(4-chlorophenyl)biguanide] digluconate, and grind at 3000rpm for 5min. The zirconia beads were separated using a 325 mesh sieve. Then, 0.5 g of TWEEN-80 was added to the ground mixed liquid, and dispersed at 4000 rpm for 5 min. Add 10 g of polyacrylate emulsion HB959 (Beijing Huyi Chemical Factory), and stir at 100 rpm for 10 min to form a milky wh...

Embodiment 3

[0039] Example 3 The soluble glass-type inorganic antibacterial agent with a silver content of 3.1%, an average particle size of 3 μm, and a maximum particle size of less than 10 μm with a weight of 6 g was moved into a 150 ml stainless steel inner barrel of a sand mill lined with polyurethane resin. 100g of zirconia beads of Φ1mm are placed in the barrel in advance. After adding 0.003g of sodium thiosulfate, add 100ml of distilled water and grind at 2000rpm for 5min. Add 0.05g of N-aminoethylaminopropyltrimethylsilane, increase the rotational speed to 3000rpm, and grind for 5min. Add 10g of 1,1'-hexamethylenebis[5-(4-chlorophenyl)biguanide] digluconate, and grind at 3000rpm for 5min. The zirconia beads were separated using a 325 mesh sieve. Then, 0.5 g of TWEEN-80 was added to the ground mixed liquid, and dispersed at 4000 rpm for 5 min. Add 10 g of polyacrylate emulsion HB959 (Beijing Huyi Chemical Factory), and stir at 100 rpm for 10 min to form a milky white suspension ...

Abstract

The invention relates to an inorganic / organic nano-composite antibacterial and application of fiber product thereof. 0.01-20 proportions of inorganic antibacterial, 0.01-35 proportions of organic antibacterial, 0.0001-0.4 proportion of inorganic / organic antibacterial compatibility finishing agent, 0.05-40 proportions of macromolecule bond, 0.0001-0.4 proportion of stabilizer that prevents color change of the inorganic antibacterial, 0.1-30 proportions of high efficiency emulsifying agent and 100 proportions of distilled water are added in sequence by weight proportion, wetted, dispersed, ground, dispersed at high-speed, stirred, etc., so as to acquire the nano-composite antibacterial. The antibacterial can process the fiber product by a dip-dye method, a roll-dye method, a spray method, etc. Dresses, socks and socks, blankets, beddings, gowns, patient wears, masks, medicinal gauzes, air filtering nettings, etc., made from the inorganic / organic nano-composite antibacterial of the invention are characterized by high antibacterial efficiency, rapid antibacterial function, long lasting antibacterial performance, laundering durability, etc., and the inorganic / organic nano-composite antibacterial of the invention is applicable to life, medical care, etc., and has the functions of preventing the occurrence and transmission of diseases, protecting the health of people and improving life quality.

Description

Technical field: [0001] The invention relates to an inorganic / organic nano composite antibacterial agent, in particular to an inorganic / organic nano composite antibacterial agent with rapid antibacterial effect and long-lasting antibacterial performance and its application in fiber products. Background technique: [0002] Antibacterial refers to the effect of inhibiting and killing bacteria and other microorganisms, including bactericidal, bacteriostatic, sterilizing, disinfecting, mildew-proof, and anti-corrosion effects (New Functional Plastic Additives, Chapter 2, Antibacterial Agents, 2003: 25). Antimicrobial agents are substances that are extremely sensitive to microorganisms, and a very small amount can inhibit the growth of microorganisms and kill microorganisms. Antibacterial agents are applied to fiber products and can be processed to produce antibacterial fiber products. The antibacterial fiber product has the ability to kill microorganisms such as bacteria that i...
