description The invention provides a preparation method of a vibration isolator with a microporous structure for rail transit, which is characterized by comprising the following steps: S1, rubber mixing: mixing raw rubber with small materials, a filler, a plasticizer, an auxiliary with a microporous structure and a vulcanization system in an internal mixer to obtain mixed rubber; step S2, rubber compound preforming: calendaring the rubber compound obtained in the step S1 to form a preformed rubber sheet with a preset thickness; and S3, pressing and vulcanization are conducted, specifically, the preformed rubber sheet obtained in the step S2 is cut into a preset size, then a plate vulcanizing machine is adopted for forming and vulcanization, and holes in a preset shape are distributed in one surface of a plate mold used in the step S3. Compared with the prior art, the vibration isolator prepared through the method has the effect of being lower in static rigidity and small in specific gravity, has the advantages of being l
