Hydrophilic-type anti-oxidation stopping agent for mines and preparation method thereof

Abstract

The invention discloses a hydrophilic-type anti-oxidation stopping agent for mines and a preparation method thereof, and relates to the field of coal spontaneous combustion inhibition for preventing and extinguishing fire in coal mines. The hydrophilic-type anti-oxidation stopping agent for the mines is prepared from high molecular base materials, an organic antioxidant, a fire extinguishing agent, a coagulant and water as raw materials; the preparation raw materials of the high molecular base material are polyacrylic acid, sodium alginate and water; the organic antioxidant is melatonin; the fire extinguishing agent is ammonium dihydrogen phosphate; and the coagulant is ammonium bicarbonate. According to the hydrophilic-type antioxidant stopping agent, the melatonin is used as the main action component for inhibiting and blocking the chain reaction in the coal spontaneous combustion process, and water absorption and water retention performance are high, the hydrophilic-type anti-oxidation stopping agent is the first in the field of the coal spontaneous combustion stopping agent, the preparation raw materials are rich in source, the preparation cost and use cost are low, the preparation process and use process are green and environmentally friendly, the chemical blocking effect and the physical blocking effect are both achieved, the self-heating of coal can be effectively prevented, and spontaneous combustion fire areas of coal can be effectively and thoroughly controlled.

Description

technical field [0001] The invention relates to the field of spontaneous combustion and chemical resistance for fire prevention and extinguishing in coal mines, in particular to a hydrophilic anti-oxidation chemical inhibitor for mines and a preparation method thereof. Background technique [0002] Coal spontaneous combustion is one of the main disaster forms that affect the safe production, storage, transportation and application of coal. The self-combustion of coal destroys coal resources, produces a large amount of toxic and harmful gases, and may induce major and serious accidents such as gas and coal dust explosions. It is an urgent problem in the field of coal mine safety production. Inhibiting chemical fire prevention technology is one of the commonly used coal spontaneous combustion prevention and control methods. Inhibitors can be divided into physical inhibitors and chemical inhibitors. [0003] The physical inhibitors are mainly inorganic salts, including halogen...

AI Technical Summary

Problems solved by technology

[0006] Technical problem to be solved: Aiming at the problems of few physical and chemical synergistic inhibitors for coal spontaneous combustion in the prior art, high cost, easy pollution and lack of chemical inhibitors that consume lipid oxygen free radicals, the present invention Provides a method for preparing a hydrophilic anti-oxidation inhibitor for mines, which has both physical and chemical resistance effects, and can chemically block the development of coal self-heating process and Strengthening, so as to eliminate the possibility of coal spontaneous combustion or recombustion of coal spontaneous combustion in essence, and has the advantages of rich sources of raw materials, low preparation and use costs, green environmental protection, etc., and can achieve efficient and safe prevention and control of coal spontaneous combustion disasters
