Abstract: An environmenta friendly fire resistant coatings for tunnel linings has been developed, which can be used In damp surroundings.The paper presented the main raw materials of intumescent fire resistant coating for tunnel linings and compared its main properties to traditional non-intumescent fire resistant coatings for tunnel linings, and drew a conclusion that the intumescent fire resistant coating for tunnel linings is featured by its thin film, longer fire resistant rating, less application time, short maintaining period and fe-wer waste.

Key words: fire resistant coating; tunnel fire; fire protection
