PROBLEM TO BE SOLVED: To provide a heat-expandable fire-resistant paint which exhibits exceptionally remarkable fire resistance performance, is safe for the human body, and can easily perform coating coating on any part. . SOLUTION: The fire-resistant paint containing butyl rubber or isobutylene rubber and an inorganic filler, wherein the butyl rubber or isobutylene rubber has a Flory having a viscosity average molecular weight of 5,000 to 4,000,000, and the butyl rubber or isobutylene rubber 100 parts by weight of the neutralized heat-expandable graphite, metal carbonate, and an inorganic filler selected from the group consisting of hydrated inorganic substances in an amount of 200 to 200 parts by weight. 500 parts by weight, the inorganic filler contains at least 15 to 400 parts by weight of neutralized heat-expandable graphite, and the viscosity of the refractory paint is 1 as measured by a B-type viscometer. Fire resistant paint of ~ 1000ps. |
