The invention discloses a self-adhesive intumescent fire stop tape, a preparation method and application thereof. The fire stop tape is composed of rubber, plastic, expandable graphite, flame retardant, tackifier, reinforcing agent and processing aids. With high-expansion graphite added, the flexible tape can be tightly wrapped around penetrating pipes or fixed at wall holes. In case of fire, it expands rapidly to seal gaps and pipelines, block flame spread and toxic gas diffusion, and gain rescue time. By optimizing the formula of plastic matrix, expandable graphite and tackifier, the product maintains high strength while possessing excellent flexibility.
