Technical Field
The invention relates to the technical field of fire-resistant waterproof plugging materials, in particular to a low-corrosion pouring type cable fire-resistant sealing filler and application thereof in cabin gap and cabin water vapor sealing.
Background
When the cable is laid on the ship, a cable channel or a perforated hole is often arranged to penetrate through the bulkhead and the deck of the ship, so that the integrity, water tightness and fire resistance of the original ship structure are damaged, and the ship is threatened by fire and water at all times when sailing or berthing. The "fuse effect" constituted by cabling also directly threatens the safety of the boat. In consideration of the safety factor of cable laying, the channel additional structure of cable laying and the through hole thereof must be sealed by fireproof sealing materials. Glass wool felt, slag wool felt, glass fiber cloth or lightweight foam glass bricks are generally used as the plugging material. Perlite powder, diatomite powder, silica powder and the like are also used as plugging materials. However, these plugging materials are not good in water-tightness and air-tightness, and also poor in weather resistance, vibration resistance and corrosion resistance, and insufficient in mechanical strength.
