Abstract

The invention discloses a fireproof blocking material for cables and belongs to the technical field of cable blocking materials. The fireproof blocking material is prepared from raw materials in partsby weight as follows: 43-55 parts of glycerol, 20-30 parts of methyl vinyl silicone rubber, 5-10 parts of zirconium oxide fiber, 18-25 parts of white carbon black, 5-10 parts of trioctyl phosphate, 20-28 parts of kaolin, 12-20 parts of asphalt, 6-12 parts of a flame retardant, 5-8 parts of a waterproof agent, 3-6 parts of a crosslinking agent and 6-10 parts of an adhesive. The fireproof blockingmaterial has good comprehensive properties; the vertical combustion level of the material reaches level V-1 and V-2, the fireproof level is level 2 and even level 3, and the material has excellent flame retardance and fire resistance and good fireproof effects; after a water resistance test, the material has a complete surface after being soaked for 3 days, does not swell or crack and has excellent waterproof performance; after a freezing and thawing resistance test, the surface of a specimen does not crack and is not pulverized. The material is long in service life, fireproof, water-resistantand resistant to freezing and thawing erosion, can be used in the low-temperature environment for a long time and has a blocking effect.

Description

technical field [0001] The invention relates to the technical field of cable plugging materials, in particular to a cable fireproof plugging material. Background technique [0002] Fireproof sealing materials are mainly used to seal various penetrations, such as various openings formed when cables, air pipes, oil pipes, air pipes, etc. pass through walls (warehouses) and floors (A) boards, as well as fire separation of cable bridges. To prevent the fire from spreading through these openings and gaps, it has excellent fire protection function and is easy to replace. Power plants, substations, and industrial and mining enterprises all use power cables in large quantities, and many cables will be laid to normal areas through an explosion and fire hazard area, and cables are flammable objects. Once the cables catch fire and explode, they will spread to other areas and cause fires. It is advisable to use flame-retardant cables for cables entering residential areas or for central...
