Fire-resistant paint and coated material thereof

摘要

The present invention is a fire-resistant paint containing butyl rubber or isobutylene rubber and an inorganic filler wherein 1 &cir& Flory's viscosity-average molecular weight of the butyl rubber or isobutylene rubber is 5,000-4,000,000; and 2 &cir& for 100 weight parts of the butyl rubber or isobutylene rubber, 3 &cir& 200-500 weight parts of the inorganic filler, chosen from a group consisting of neutralized thermally expandable graphite, metal carbonate, and a hydrated inorganic compound is contained; 4 &cir& for the inorganic filler, at least 15-400 weight parts of neutralized thermally expandable graphite is contained; and 5 &cir& the viscosity of the fire-resistant paint is 1-1,000 ps as measured by a B-type viscometer. The fire-resistant paint of the present invention has particularly remarkable fire resistance, and can be used in a wide range of applications.
