Anti-corrosion anti-permeability fire-retardant coating

Abstract

The invention discloses an anti-corrosion anti-permeability fire-retardant coating comprising the following raw materials by weight: 50-80 parts of Portland cement, 10-15 parts of polymer emulsion, 15-20 parts of expanded perlite, 10-20 parts of talcum powder, 3-6 parts of granite, 10-15 parts of graphite powder, 5-7 parts of magnesium hydroxide, 5-7 parts of aluminum hydroxide, 0.3-1.5 parts of silicon alkyl powder, 3-5 parts of pentaerythritol, 2-3 parts of a concrete expansion agent, 6-8 parts of mica powder, 1-3 parts of aluminum dihydrogen tripolyphosphate and 1-3 parts of zinc borate. The anti-corrosion anti-permeability fire-retardant coating is used for under coal mine well coal seams, has the advantages of excellent fire-retardant heat-insulating property, good coal adhesion, good anti-permeability waterproof property, good antistatic property, good water, acid and alkali and salt corrosion resistance, storage stability, no toxicity and environmental protection, and the like, and can meet the requirements of irregularity of the surface of the coal seams and self deformation of the coal seams, and crack phenomenon is not easy to cause.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to an anti-corrosion and anti-seepage type fireproof coating for underground coal seams of coal mines. Background technique [0002] Coal mine fire is one of the five major disasters in mines. In coal mines, coal itself is a large and ubiquitous combustible substance; secondly, a large amount of coal dust, gas, and electromechanical Substances such as explosives and oil are flammable. Once a fire breaks out in the mine, the speed of fire development is fast, it is inconvenient to control, and it is very easy to cause casualties. In order to improve the ability of coal mines to resist fire, it is one of the effective methods to spray fireproof coatings on coal bodies in coal mines. Due to the dampness of the underground coal wall in coal mines, water leakage is common, the coal wall is rough and uneven, the coal wall will slowly deform, and contains a large amount of gas...

AI Technical Summary

Problems solved by technology

Due to the dampness of the underground coal wall in coal mines, water leakage is common, the coal wall is rough and uneven, the coal wall will slowly deform, and contains a large amount of gas, which requires antistatic properties. Poor electrostatic performance, poor adhesion, no elasticity, easy to crack and fall off, poor water resistance, etc.
