Title:
防煙テープ
Document Type and Number:
Japanese Patent JP5628580
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a smoke-tight tape capable of effectively preventing origin smoke from being diffused through a building even in an initial time of fire breakout.SOLUTION: A smoke-tight tape 11A, which is attached to the partition wall clearance of an opening/closing door, etc. in a building, and is thermally expanded in the direction of the clearance in case of fire breakout to close the partition wall clearance, consists of a powdery or pasty thermal expansion agent 12 filled in a substantially flat cross-sectional band-like bag 13A. The thermal expansion agent 12 contains a microcapsule aggregate encapsulating a volatile liquid, and the microcapsule aggregate can be thermally expanded by evaporation of the volatile liquid. The band-like bag 13A bulges in the thickness direction due to thermal expansion of the microcapsules to close the partition wall clearance.
