Examples
Embodiment 1
[0042] According to the data of Example 1 shown in Table 1, the elastic ionomer and nano-state airgel were weighed and mixed uniformly to obtain a mixed raw material. ;
[0043] Put the dried mixed raw materials into a closed reaction kettle, vacuumize the reaction kettle and fill it with inert nitrogen to protect it to normal pressure, then heat it to 190°C and keep it at a constant temperature, and stir at a constant speed of 120 rpm for 30 minutes , then add the silver ion antibacterial agent in proportion, continue to stir for 10 minutes, fill with nitrogen and pressurize, export the molten blend from the bottom outlet of the closed reactor, cool, and pelletize to obtain functionalized masterbatch.
Embodiment 2
[0045] According to the data of Example 2 shown in Table 1, the elastic ionomer and nano-state airgel were weighed and mixed uniformly to obtain a mixed raw material. ;
[0046] Put the dried mixed raw materials into a closed reaction kettle, vacuumize the reaction kettle and fill it with inert nitrogen to protect it to normal pressure, then heat it to 190°C and keep it at a constant temperature, and stir at a constant speed of 120 rpm for 30 minutes , then add the silver ion antibacterial agent in proportion, continue to stir for 10 minutes, fill with nitrogen and pressurize, export the molten blend from the bottom outlet of the closed reactor, cool, and pelletize to obtain functionalized masterbatch.
