The invention discloses a heat-resistant coating composition which is prepared from the following components in parts by weight: 30-35 parts of fine aggregate, 2-10 parts of hexatitanate whisker, 30-40 parts of a film-forming agent and 1-5 parts of a curing agent, the film-forming agent is sodium silicate; the curing agent is potassium fluosilicate; the fine aggregate is prepared from the following components in percentage by weight: 35-45% of hollow glass beads, 5-20% of rock fibers, 2-10% of zircon sand and the balance of rutile type titanium dioxide. The heat-resistant coating composition has outstanding advantages in the aspects of stability, heat resistance, water resistance, film-forming property and the like. According to the preparation method of the heat-resistant composition provided by the invention, the prepared film is good in quality, and the thermal expansion coefficient can reach 1.0 * 10 <-6 >/DEG C. 本发明公开了一种耐热涂料组合物，包括按重量份计的以下组分制成：30-35份细骨料、2-10份六钛酸晶须、30-40份成膜剂和1-5份固化剂；所述成膜剂为硅酸钠；固化剂为氟硅酸钾；所述细骨
