Problems solved by technology

[0005] The disadvantages of the above-mentioned patents are: although the foam multiple of the fire extinguishing agent can reach 20 to 200 times, and the foam stability time is ≥ 2.5 hours, it can only make the "inert gas carbon dioxide foam spread in the fire zone and fill its space in a short time." , so that the oxygen concentration in the fire area drops rapidly, causing the fire area to suffocate due to lack of oxygen", it cannot really isolate the contact between the burning coal seam and the air, prevent the coal mine from continuing to burn, avoid the re-ignition of the coal seam, and achieve flame retardancy and fire prevention. Purpose
[0009] The deficiencies of the above-mentioned patents are: the sodiumization of bentonite simply adopts "rotary cultivator cutting and crushing", "turning shovel and mixing-aging" and "utilizing the moisture of bentonite itself to dissolve sodium carbonate and montmorillonite the constituent minerals of bentonite". Sodium carbonate undergoes a displacement reaction to carry out sodiumization”, and sodium carbonate cannot completely sodiumize with montmorillonite, and the effect of sodiumization is not good; At 0.5-2%", when the water content of bentonite after sodiumization is less than 2%, the quality of sodium bentonite will be directly affected, and the colloidal viscosity of bentonite will be greatly reduced, which is not conducive to improving the performance indicators of sodium bentonite

Embodiment Construction

[0065] Below in conjunction with embodiment the present invention will be further described:

[0066] 1. The batching of bentonite reticulated gel foam mud fire extinguishing agent consists of the following components by weight percentage: 26% of bentonite composite flame retardant foaming agent, 22% of inorganic fiber spray cotton mixture and 52% of water;

[0067] The production method of the bentonite reticulated gel foam mud fire extinguishing agent: input the ingredients of the bentonite reticulated gel foam mud fire extinguishing agent into the rake type mixer, and stir at a high speed to be the bentonite reticulated gel foam mud fire extinguishing agent, The speed of the rake mixer is controlled at 2400-2800 rpm, and the stirring time is controlled at 12 minutes.

[0068] 2. The ingredients of bentonite composite flame retardant foaming agent are composed of the following components by weight percentage: bentonite composite flame retardant foaming agent paste 38%, hydro...

Abstract

The invention discloses a bentonite reticular gel foam mud fire prevention and extinguishing agent, and the key point of the technical scheme is that the fire prevention and extinguishing agent is composed of a bentonite composite type flame-retardant foaming agent, an attapulgite clay powder with an air purifying function, inorganic fiber spraying cotton, a sodium-modified bentonite powder, a coal gangue powder, an expanded perlite powder, sodium alginate and water. The ingredients of the bentonite reticular gel foam mud fire prevention and extinguishing agent are inputted into a plow harrow type material mixing machine and are subjected to high speed mixing into the bentonite reticular gel foam mud fire prevention and extinguishing agent. Reticular gel foam mud is jetted to a burning coal layer by an inorganic fiber spraying machine, so as to be beneficial for generation of an integral reticular gel foam mud film in the fire prevention and extinguishing process, the integral reticular gel foam mud film covers and adheres to the surface of the ore layer all the time, contact of the burning coal layer with air is rapidly isolated, coal mines are prevented from continuing to burn, the coal layer is avoided from reburning, and the purposes of flame retardancy and fire prevention and extinguishing are reached; and the bentonite reticular gel foam mud fire prevention and extinguishing agent is applicable to coal mines, mine operating areas and forest fire prevention and extinguishing.

Description

technical field [0001] The invention relates to an anti-fire extinguishing agent, in particular to a bentonite reticulated gel foam mud anti-fire extinguishing agent. Background technique [0002] Fully mechanized top-coal caving mining has the advantages of high yield, high efficiency, and low consumption, and has been widely used in many coal production bases in my country. However, due to the high mining intensity of this coal mining method, there is a lot of residual coal left in the goaf, the height of the fall is large, and the air leakage is serious. A series of problems such as fire, gas, and dust that are difficult to solve often occur, especially fire. [0003] Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam. [0004] Chinese Patent Publication No. CN 102614615A, publication date: August 01, 2012, titled "a composite foam fire extinguishing agent for coal mine undergr...
