The fireproof sealing material is endowed with excellent expansion performance by adding fireproof expandable graphite powder combined with high-concentration cement foaming agent and cement foam stabilizer. After fire and heat, it expands and deforms to fill the hole of the electric shaft and move up and down the hole. The two ends overflow, thereby effectively inhibiting the spread of fire and playing a very good fire-blocking effect, which solves the problem that the structure of the construction project tank is not strong, easy to fall off, and easy to crack when it is made of fire-proof rock wool fire-proof mud and other materials

Embodiment 1
[0027] The fireproof sealing material of this embodiment is prepared from the following components in parts by mass: 310 parts of asbestos wool, 125 parts of gypsum, 62 parts of cement, 28 parts of perlite, 21 parts of fireproof expanded graphite powder, 78 parts of water, high Concentrated cement foaming agent 4.7 parts, cement foaming stabilizer 1.05 parts.
[0028] The preparation method of this example: mix asbestos wool, gypsum, cement, perlite and fireproof expanded graphite powder evenly to obtain a mixed dry material, then add highly concentrated cement foaming agent and cement foaming stabilizer to water to dissolve and dilute , to obtain a mixed solution, and then add the mixed solution to the mixed dry material and stir until it is in a semi-wet state, and the mixed material of the fireproof plugging material is obtained based on the fact that it does not disperse after being held by hand.
Embodiment 2
[0030] The fireproof sealing material of this embodiment is prepared from the following components in mass parts: 270 parts of asbestos wool, 110 parts of gypsum, 57 parts of cement, 27 parts of perlite, 18 parts of fireproof expanded graphite powder, 75 parts of water, high 4 parts of concentrated cement foaming agent, 0.9 part of cement foaming stabilizer.
[0031] The preparation method of this embodiment is the same as that of Example 1.
Embodiment 3
[0033] The fireproof sealing material of this embodiment is prepared from the following components in parts by mass: 330 parts of asbestos wool, 130 parts of gypsum, 63 parts of cement, 33 parts of perlite, 22 parts of fireproof expanded graphite powder, 85 parts of water, high Concentrated cement foaming agent 6 parts, cement foaming stabilizer 1.1 parts.
[0034] The preparation method of this embodiment is the same as that of Example 1.

Abstract
The invention discloses a fireproof sealing material, which is prepared from the following components in parts by mass: 270-330 parts of asbestos wool, 110-130 parts of gypsum, 57-63 parts of cement, 27-33 parts of perlite, and is fireproof 18-22 parts of expanded graphite powder, 75-85 parts of water, 4-6 parts of high-concentration cement foaming agent, 0.9-1.1 parts of cement foaming stabilizer; the invention also discloses a tank box of fireproof sealing material The construction method is to install the formwork after cleaning the opening of the electrical shaft and build a waterproof platform, and fill the mixture of fireproof sealing materials between the tank box and the formwork and between the tank box and the cable gap inside. The present invention endows the fire-proof sealing material with excellent expansion performance by adding fireproof expandable graphite powder combined with high-concentration cement foaming agent and cement foam stabilizer, and effectively inhibits the spread of fire; the present invention adopts semi-wet mixing method to improve the The structural stability and construction speed of the fireproof sealing material.
Description
technical field [0001] The invention belongs to the technical field of fire prevention construction, and in particular relates to a fire prevention sealing material and its application in a tank box construction method. Background technique [0002] The electrical lines in high-rise buildings are responsible for the power transmission and the energy supply of the entire building, while the cables of the power distribution system are generally laid in the slot box of the electrical shaft. Once a fire occurs in an electrical line, the flame will spread and expand along the cable. The fire is not easy to be controlled in a short time, and it is not easy to be extinguished in a local area, resulting in great losses. Therefore, it is necessary to carry out fire prevention and sealing. Usually, materials such as fireproof rock wool and fireproof mud are used for fireproof sealing of the tank box, but the structure is not firm, easy to move, easy to fall off, easy to crack, etc., a...
