The invention relates to a hot-melt pressure-sensitive adhesive, a preparation method thereof and a waterproof coiled material. The hot-melt pressure-sensitive adhesive comprises the following components: a styrene-isoprene-styrene block copolymer; butyl rubber/graphene composite rubber; a plasticizer; a tackifying resin; an anti-aging agent; a silane coupling agent; a cross-linking agent; and a cross-linking promoting auxiliary agent. The hot-melt pressure-sensitive adhesive provided by the embodiment of the invention contains the butyl rubber/graphene composite rubber and the styrene-isoprene-styrene block copolymer (SIS block copolymer), graphene is of a lamellar structure, large in specific surface area and good in hydrophobicity, butyl rubber is non-polar rubber and good in water tightness, and the hot-melt pressure-sensitive adhesive has the advantages that the hot-melt pressure-sensitive adhesive can be used for hot-melt pressure-sensitive adhesive bonding; after graphene and butyl rubber are compounde
