Problems solved by technology

Due to its structural characteristics, this kind of cable has low fire resistance temperature and low fire resistance reliability.
There are also fillers made of glass filaments, but the fillers will ash and smoke when burned at high temperatures
In the event of a fire, ordinary fire control cables cannot guarantee that the line will continue to work, and it is difficult to fight for a longer time for escape and rescue

Abstract

The invention relates to a fireproof and flame retardant mineral compound filling material for cables. The filling material comprises a silicon-containing binder; an inorganic flame retardant compound; and a mineral compound. The filling material also can include a silicate modifier, a silicate curing agent and a pigment. Being free of any flammable substance, the fireproof and flame-retardant mineral compound filling material provided in the invention has an excellent fireproof effect, can lose moisture and absorb a lot of heat so as to achieve the flame retardant effect. With good flexibility, the fireproof and flame retardant mineral compound filling material has no hazard to the nature after it is abandoned.

Description

technical field [0001] The invention relates to a mineral compound filler, in particular, the invention relates to a fireproof and flame-retardant mineral compound filler for electric cables. The invention also relates to a cable containing the filler. Background technique [0002] With the acceleration of industrialization and urbanization, various types of fire accidents also occur frequently, causing huge losses of life and property. Moreover, with the improvement of fire protection awareness, some electrical distribution lines in developed countries must choose fireproof cables according to different purposes. The domestic power sector is also promoting the use of fire-resistant cables in high-rise buildings and entertainment venues in cities. [0003] The insulating layer containing mica tape and ceramic composite tape is the main fire-proof and flame-retardant structure of the cable. The fire resistance of the cable is achieved through the chemical reaction of cerami...
