Coal spontaneous combustion inorganic inhibitor and using method thereof

Abstract

The invention discloses a coal spontaneous combustion inorganic inhibitor and a using method thereof. The coal spontaneous combustion inorganic inhibitor is composed of the following raw materials of, by weight, 80-100 parts of magnesium chloride, 5-10 parts of sarcosyl, 10-15 parts sodium gluconate, 2-6 parts of fatty acid soap, 1-5 parts of sulfate, 1-8 parts of stearic acid and 4-8 parts of sodium chloride. The coal spontaneous combustion inorganic inhibitor can form a liquid film on the surface of coal, is excellent in compactness, film forming performance and wall attachment performance, further has the oxygen insulation and inhibition effects, has the functions of cooling, heat insulation, oxygen insulation and air insulation and achieves the flame retardant effect and the fire preventing and extinguishing effects.

Description

technical field [0001] The invention relates to the field of thermoplastic materials, in particular to an inorganic inhibitor of spontaneous combustion of coal and a method for using the same. Background technique [0002] In chemistry, any substance that can reduce the speed of a chemical reaction is called an inhibitor. Sodium alginate, sodium silicate and high-absorbent resin as the main raw materials such as gel-type fire-preventing materials also have a certain inhibitory effect on coal spontaneous combustion. Colloids are used to wrap the coal body to isolate the coal body from oxygen in the air. achieve the goal of resistance. This type of inhibitor is expensive, and it also belongs to the type of physical inhibitor. However, due to the mine pressure and the physical and chemical changes of the coal itself, the effect of wrapping and insulating oxygen is often destroyed, and the purpose of preventing spontaneous combustion of coal cannot be achieved.
