Abstract

The relates to a fireproof seal filler for ship cable transfixion channel and opening and preparing method thereof, which belongs to flame-proof sealing material technique field. Components and weight percent of raw materials employed by the invention are that: kaolin of 10-20%, talcum powder of 5-10 % and silicon micro-powder of 30-50% are used as base-material; aluminum hydroxide of 10-20%, hydrated zinc borate of 5-10% and magnesium hydroxide of 10-20% are used as flame retardant; wherein proportion of the base-material and the flame retardant is 1:1-2.3:1; in addition, coagulants of calcium sulfate, calcium chloride, magnesium chloride and sodium carbonate are added, weight percents of the four coagulants are separately 20-40% based on total weight of the base-material and the flame retardant as 100%. Firstly the coagulant is mixed with water to prepare serum, when actually using, the serum is added in mixed powder material of the base-material and the flame retardant, and the pasty fireproof seal filler is obtained by sufficiently stirring of highly effective stirring machine.

Description

technical field [0001] The invention relates to a fireproof sealing packing used for ship cable penetration channels and openings and a preparation method thereof, belonging to the technical field of fireproof sealing materials. Background technique [0002] When the cable is laid on the ship, it is often necessary to lay cable trenches or punch holes to penetrate the bulkhead and deck of the ship, which destroys the integrity, watertightness and fire resistance of the original hull structure, and makes the ship sailing or mooring. Always facing the threat of "fire" and "water". The "fuse effect" formed by cable laying also directly threatens the safety of ships. Considering the safety factor of cable laying, the additional structures in the cable laying trench and the openings through which they pass must be sealed with fireproof sealing materials. Usually, glass wool felt, slag wool felt, glass fiber cloth or lightweight foam glass bricks are used as plugging materials. ...
