The preparation method comprises stepsas follows: step one, nitrile rubber is added to a stirrer and stirred uniformly, and is mixed and stirred uniformly with vinyltriisopropenyloxysilane, phenyltrimethoxysilane, octadecyl acrylate and ethylene glycol dimethacrylate; step two, nano-silica, polyvinyl alcohol, vinyl phenyl silicone oil, an emulsifier and a vulcanizing agent are added to an extruder for extrusion; step three, an extrudate and deionized water are added to the stirrer for continuous mixing and stirring; step four, a stirred substance is subjected to high-temperature desulfurization for a period of time, and plastic rubber is obtained; step five, the desulfurized plastic rubber passes through an open mill and a refining mill in sequence, and the anti-seismic and high-temperature-resistant glue is obtained. With theadoption of the technical scheme, the anti-seismic and high-temperature-resistant glue has good binding property, is not prone to falling off, has temperature resistance up to 200-300 DEG C, can be used for a long time and has certain anti-seismic capacity.
