Abstract

The invention discloses fireproof mud used for installation of a power cable, and belongs to the technical field of fireproof mud. The fireproof mud is composed of, by weight, the raw materials of 25-28 parts of condensed polycyclic aromatic hydrocarbon resin, 15-20 parts of epoxy resin, 8-10 parts of chlorinated paraffin, 14-18 parts of clay, 11-13 parts of porcelain clay powder, 7-9 parts of perlite, 6-9 parts of quartz sand, 5-7 parts of bauxite chamotte, 2-4 parts of magnesium hydroxide, 6-8 parts of tributyl citrate, 4-6 parts of ethylene glycol, 7-9 parts of ammonium phosphate, 2-4 parts of antioxidant, 1-2 parts of anti-corrosion agent and 1-3 parts of antistatic agent. The invention further discloses a preparation method of the fireproof mud used for installation of the power cable. The fireproof mud is easy to prepare, environmentally friendly, low in pollution and good in durability, and has the effects of good fire resistance, corrosion resistance, water resistance and static resistance.

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...
