[0037] Further, the preparation method of described composite acrylic glue comprises the following steps:
[0038] S11, put acrylic glue, inorganic filler, anti-aging agent, antibacterial and antifungal agent, coupling agent and plasticizer into the temperature-controllable reaction kettle, raise the temperature to 75°C, start the stirrer to stir for 35min-40min, and the stirring speed is 155r / min~160r / min, the mixture A is prepared at this time;
[0039] S12, send the carbon nanotubes and lithium sulfate into the reaction kettle, adjust the stirring speed to 310r / min-350r / min, and obtain the composite acrylic glue after stirring evenly.
[0040] Further, the plasticizer is an epoxy plasticizer.
[0041]Further, the specific steps of defoaming casting technology in S2 are as follows: coating the polyamic acid added with nano aggregates on the carrier, sending it into a tunnel oven, raising the temperature in stages, at 345°C to 250°C , heated for 35min-40min, and then reacte...
