specific Embodiment approach

[0012] The loess composite gel fire extinguishing material for mining of the present invention, its preferred embodiment is:

[0013] It includes a base material, a coagulant and aggregate, the base material is water glass, the coagulant is polyacrylamide, and the aggregate is loess.

[0014] The mass parts of the base material, coagulant and aggregate are respectively: 5-8 mass parts, 1-5 mass parts, 100-180 mass parts, and the remaining 100-120 mass parts are water.

[0015] The preparation method of the above-mentioned mine-used loess composite gel fire-proofing material of the present invention, its preferred embodiment is:

[0016] First mix the base material and the coagulant, mix the aggregate and water, and then mix the two slurries and stir at a rate of 90 rpm for 2 to 3 minutes to obtain the product. At this time, the viscosity of the slurry increases obviously, and continue to stir There will be no noticeable change.

[0017] The mine-used loess composite gel anti...

Abstract

The invention claims a mine loess composite gel fire preventing and extinguishing material and a preparation method of the material. The mine loess composite gel fire preventing and extinguishing material comprises a base material, a coagulation accelerator and an aggregate, wherein the base material is sodium silicate; the coagulation accelerator adopts polyacrylamide; and the aggregate is loess. The preparation method disclosed by the invention comprises the following steps of: firstly, mixing the base material and the coagulation accelerator and mixing the aggregate and water, and subsequently, mixing and stirring two slurry solutions to acquire the product. The mine loess composite gel fire preventing and extinguishing material is low in cost, great in viscosity and good in stability.

Description

technical field [0001] The invention relates to a fire-proofing material for coal mines, in particular to a loess composite gel fire-proofing material for mines and a preparation method thereof. Background technique [0002] At present, the coal mine safety situation has not been effectively curbed, and major disasters and accidents occur from time to time. Coal mine fires are mainly due to the natural ignition of coal. Due to air leakage into the loose coal body, the surface active structure of coal molecules contacts with oxygen in the air, physical adsorption, chemical adsorption and chemical reactions occur, and heat is released at the same time. Under a certain heat storage environment, coal When the temperature of the coal body exceeds its critical temperature, the temperature continues to rise until it reaches the ignition point, which eventually causes the coal body to burn and cause a coal mine fire. Spontaneous combustion of coal is the result of heat released by ...
