Embodiment A1
[0050] The preparation method of silver nanowire composite auxiliary agent sample A1 is as follows:
[0051] (1) Add 50 parts of distilled water into the reaction kettle, then add 20 parts of neopentyl glycol, heat to 40°C, add 0.6 parts of hexamethylenetetramine to adjust the pH value to 8.5±0.1, and obtain buffered neopentyl glycol coupling agent solution;
[0052] (2) Keep the reactor at 40°C, add 10 parts of silver nanowires and 10 parts of active nano-zinc oxide into the buffered neopentyl glycol solution, control the temperature of the material at 45°C, stir for 25 minutes, and cool to room temperature through the jacketed water of the reactor , through infiltration and coupling to prepare silver nanowire composite antibacterial additives.
Embodiment A2
