Description

technical field

[0001] The invention relates to the technical field of fireproof mud, in particular to a fireproof mud for power cable installation and a preparation method thereof. Background technique

[0002] Fireproof mud is a kind of flexible flame-retardant material, which has the characteristics of high fire-resistant limit and low smoke emission. Reduce fire damage. To avoid the expansion of accidents, it has the functions of smoke resistance, fire prevention and dust prevention. Therefore, the plugging material is widely used in vertical and horizontal wire and cable penetration holes in power plants, industrial and mining enterprises, high-rise buildings, shipbuilding power, post and telecommunications, substations, metallurgy and other system engineering.

[0003] However, the current fireproof mud has poor service life and poor environmental protection during use. It has insufficient fire resistance, smoke blocking, oil resistance, water resistance, and corrosi...
