摘要

PROBLEM TO BE SOLVED: To provide a fire resistive rubber composition whose foamed body has sufficient flame retardancy and shape stability even when exposed to flame heat, which can provide excellent working efficiency to a fire resistive covering material obtained by forming the composition. SOLUTION: This unvulcanized fire resistive rubber composition at least contains 3-50 pts.mass of tackifier, 10-100 pts.mass of thermally expansive graphite, 30-180 pts.mass of flame retardant, 30-210 of inorganic filler, 0.1-10 pts.mass of vulcanizer and 0.1-10 pts.mass of vulcanization promoter, relative to 100 pts.mass of base rubber component consisting of 30-60 pts.mass of liquid rubber and 40-70 pts.mass of butyl rubber. The fire resistive covering material formed from the fire resistive rubber composition and a fire resistive covering method using the fire resistive coating material are also provided.
