The invention discloses a paint containing petroleum asphalt and expanded perlite. The paint is prepared from the following raw materials in parts by weight: 100 to 120 parts of petroleum asphalt, 20 to 30 parts of expanded perlite, 11 to 14 parts of iron oxide red, 10 to 15 parts of tourmalinite powder, 10 to 20 parts of mica powder, 5 to 10 parts of titanium dioxide, 8 to 10 parts of lime putty, 6 to 9 parts of sodium citrate, 2 to 3 parts of barium chloride, 35 to 45 parts of clay, 30 to 40 parts of polyvinyl alcohol, and 1 to 3 parts of magnesium silicate. The paint has the advantages of excellent elongation percentage, extremely high compressive strength, and good anticorrosive performance, the thermal insulation and fireproof function are integrated, and the high temperature resistant performance is very good.
