Abstract: A scald-resistant synthetic leather includes a silicone layer and a high-temperature resistant substrate disposed in sequence from top to bottom. A preparing method includes coating and vulcanizating a silicone slurry on the high-temperature resistant substrate, after coating the silicone slurry, sending the high-temperature resistant substrate and the silicone slurry to a drying tunnel for vulcanization to allow attachment of the silicone layer and the high-temperature resistant substrate; after the vulcanization, peeling the silicone layer and the high-temperature resistant substrate apart to obtain the scald-resistant synthetic leather; the number of processes of coating and vulcanizating is more than one, and a thickness for a single coating is 0.02-3 mm; a total thickness for coating is 0.2-0.5 mm. The silicone slurry and the high-temperature resistant substrate used in the disclosure both are environmentally friendly and harmless materials. The high-temperature resistant substrate provides a fundamental framework, and the silicone slurry is the cover.
