Embodiment 1
[0027] Dilute 10 parts to a concentration of 1×10 -4 g / ml of benzalkonium bromide solution was added dropwise to 10 parts with a concentration of 1.5×10 -3 g / ml AgNO 3 solution, stir evenly to obtain mixed system A. Dilute 50 parts to a concentration of 1 x 10 -5 g / ml sodium borohydride and 50 parts at a concentration of 1 x 10 - 4 The benzalkonium bromide solution of g / ml was stirred and mixed to obtain the mixed system B. Add the mixed system B to the mixed system A dropwise, and control the addition within 1.5h, stir evenly to obtain the nano-silver solution. Get 10 parts of nano-silver solution, add 1 part of 1 μg / ml butylparaben, stir at room temperature and use concentration as 0.1mol / L NaOH solution or 0.1mol / L HCl solution to adjust the pH value to 4.5 to obtain Nano silver composite antibacterial agent.
Embodiment 2
[0029] Dilute 50 parts to a concentration of 2 x 10 -4 g / ml of benzalkonium bromide solution was added dropwise to 20 parts with a concentration of 1.5×10 -3 g / ml AgNO 3 solution, stir evenly to obtain mixed system A. Dilute 50 parts to a concentration of 1 x 10 -5 g / ml of hydrazine hydrate and 50 parts at a concentration of 2 x 10 - 4 The benzalkonium bromide solution of g / ml was stirred and mixed to obtain the mixed system B. Add the mixed system B to the mixed system A dropwise, and control the addition within 1.5h, stir evenly to obtain the nano-silver solution. Get 10 parts of nano-silver solution, add 1 part of 1 μg / ml butylparaben, stir at room temperature and use concentration as 0.1mol / L NaOH solution or 0.1mol / L HCl solution to adjust the pH value to 4.5 to obtain Nano silver composite antibacterial agent.
Embodiment 3
[0031] The concentration of 50 parts is 3×10 -4 g / ml of benzalkonium bromide solution was added dropwise to 50 parts with a concentration of 1.5×10 -3 g / ml AgNO 3 solution, stir evenly to obtain mixed system A. Dilute 100 parts to a concentration of 1 x 10 -5 g / ml sodium borohydride and 50 parts at a concentration of 3 x 10 - 4 The benzalkonium bromide solution of g / ml was stirred and mixed to obtain the mixed system B. Add the mixed system B to the mixed system A dropwise, and control the addition within 1.5h, stir evenly to obtain the nano-silver solution. Take 20 parts of nano-silver solution, add 5 parts of 2 μg / ml butylparaben and 2 parts of 2 μg / ml isothiazolinone, stir well at room temperature and use a concentration of 0.1mol / L NaOH solution or a concentration of 0.1mol / L HCl solution to adjust the pH value to 4.5 to obtain a nano-silver composite antibacterial agent.
