<p>PURPOSE:To provide a softening sheet for a flame propagation-preventing material, capable of softening easily and in a short period of time the flame propagation-preventing materials that have already been laid, without being restricted by the kind of materials and laying faces, and useful in the case of removing a cable from a laid line in which such application of flame propagation-preventing materials has been carried out. CONSTITUTION:The sheet is formed of a softening material layer 2 composed of a slurry-like intimate mixture in which 100 pts.wt. of ethyl acetate, 200 pts.wt. of clay and 20 pts.wt. of NBR are mixed together, a fire-resistant fiber cloth 3, and a composite airtight film 4 having a high-density polyethylene film 4b laminated on an aluminum film 4a, wherein each of the layer 2, the cloth 3 and the film 4 is laminated on the surface of an airtight film 1 in order named. Further, an adhesive tape 5 is stuck on both side faces of the sheet thus formed.</p> |
