Abstract

The invention relates to an organic deoxygenated composite retardant for preventing spontaneous combustion of coal and a preparation method of the organic deoxygenated composite retardant. The composite retardant is prepared from a mixed solution of glucose and sodium hydroxide and a retardant, wherein the weight ratio of glucose to sodium hydroxide to the retardant is (8 to 10): 1: (0.1 to 0.3).The preparation method comprises the following steps: collecting glucose and sodium hydroxide according to the ratio, preparing a glucose solution and a sodium hydroxide solution of a corresponding mass fraction, and mixing to obtain a deoxidant solution; and adding the retardant into the deoxidant solution, and uniformly stirring to obtain the organic deoxygenated composite retardant for preventing the spontaneous combustion of coal. The preparation method is simple, and a product for preventing the spontaneous combustion of the coal can play a role in preventing the oxidation of active groups of the coal and preventing the coal from absorbing oxygen surrounding the residual coal; and the product has the characteristic similar to the traditional retardant that can be prepared into a solution, so that the organic deoxygenated composite retardant can be applied to the places of underground opening and closed gobs and coal walls with two-lane two-line crack development and the like in the aspect of preventing the spontaneous combustion of underground coal in coal mines and is wide in application range.

Description

Technical field: [0001] The invention belongs to the technical field of fire prevention and extinguishing materials for coal mines, and in particular relates to an organic deoxidation type composite inhibitor for preventing coal spontaneous combustion and a preparation method thereof. Background technique: [0002] Coal spontaneous combustion disasters cause serious safety accidents and environmental pollution. In order to promote the continuous development of coal spontaneous combustion prevention and control technology, adapt to the complexity of coal mine production conditions and the diversity of coal spontaneous combustion in my country, further curb the occurrence of disasters, reduce economic losses and casualties , Inhibitor (generally use inorganic salt MgCl 2 , NaCl, CaCl 2 etc.) Fire prevention is an important technical means. However, the inhibitor can only reduce the chance of coal contacting with oxygen, but cannot reduce the surrounding oxygen concentration, ...
